Nortel Nortel techniques
Detroit, MI--the long run has arrived. thanks to the efforts of design teams from regular Motors (GM), Daimler-Chrysler, and Ford, thought vehicles are exploring new roads. SUVs, minivans, sports vehicles, coupes, and sedans are crossing paths, growing a brand new entry of cars, a metamorphosis in case you will.
among the conception introductions at the North American overseas Auto display:
visual interest. universal Motors (GM) introduced five vehicles at the exhibit, they include the Pontiac Aztek, Buick Cielo, Oldsmobile Recon, Cadillac Evoq, and Chevrolet Nomad. To design these cars, engineers are using Alias utility's 2nd digital sketching, paintbox, 3D digital modeling, and 3D visualization tools.
every company has its personal design core that properties displays to inspire new vehicle ideas. Kate Zak, a developer of manufacturer center characters, comments that GM desires its engineers to grasp what the center of attention is, what it seems like.
Such reveals include Speedforms, a standard sculpture of the particular person manufacturers' shape that helps engineers maintain the conception's focal point and the mannequin's theme. a tumbler case houses the brightest, boldest items, such as the existing Nike sneaker, which affect automobile design and hold engineers privy to buyer wishes and desires.
Tom Peters, one member of the Pontiac Aztek design team, recalls going looking together with his youngsters and being captivated with the aid of a yellow/grey jacket. products such as this equipment, says Peters, stimulate a visual activity and contain substances to entice the consumers. He comments that sports bikes are a further eye-catcher, particularly people that feature exposed structural points.
or not it's items and designs corresponding to these that the design groups adopted for Pontiac Aztek, which combines the fundamental aspects of an SUV, sedan, and van into one automobile. The Aztek, says design crew member Phil Kuchera, is "in the hunk appear, with a twin-port exhaust. Its profile is most dominant, a whole new animal, not a Clint Eastwood however rather an Arnold Schwarzenegger."
This 4-door hatchback seats 4 passengers and contours a 3.4l V6 200-hp engine with 225 lb feet of torque mated to a four-speed computerized transmission. This aggregate makes it viable to tow as much as three,500 lb--adequate vigour to trailer not one, but two SeaDoo very own watercraft.
The automobile offers front-wheel drive with traction manage and rack-and-pinion guidance. different aspects include MacPherson totally impartial entrance struts, open-section twist-axles with essential stabilizer bar, and gas shocks with coil springs within the rear.
inner, the titanium and textured-leather instrument panel facets a fully uncovered floating-instrument cluster pod with circular analog gauges peer out of a titanium face plate.
The pod points Delphi Delco digital system's extremely-Lite expertise that makes use of a skinny sheet of acrylic to effectively channel mild to the yellow fundamental display photos. At night, the monitor takes on a 3D seem.
The panel also points a driver tips core with developed-in heads-up screen and multifunction liquid crystal display. The lcd reveal offers driver suggestions middle messages, time and radio-station readouts, and navigational information.
The main display screen additionally controls Pioneer's top rate visible audio device. This gadget features a radio with CD changer handle, two lcd displays, DVD, six-disc multi-CD changer, cordless far flung handle, and 10 audio system. The door speakers characteristic Pioneer's low-profile Kevlar(R) cone and neodynium-magnet circuit know-how for loud, clear sound.
The Pontiac Aztec is is only one illustration of how GM is relocating design. one more is a new spin on modern day convertible.
"A no-compromise vehicle." it truly is how the Buick Cielo's design crew described this idea, which they say offers the consolation of a sedan with the with the open-air enjoyment of a convertible.
This thought is designed from a essentially math-primarily based system that involves huge use of computers, 3D modeling, computer sketches, rendering, and creation of a foam, no longer clay, model. This four-door convertible seats five and contours a 3.eight liter supercharged V6 engine with four-speed auto transmission.
The Cielo features large-opening doors, a dual head-up monitor, voice-activated programs (akin to a retractable roof it's either voice or button operated), air bags (hooked up within the roof rails), and a shift-by using-wire roof (a sunroof that opens to various levels). The ignition is keyless.
Cielo's two roof rails run between the entrance of the passenger compartment and the rear conclusion, strengthening the basic physique and allowing use of three difficult roof panels that slide into the trunk when the driver wishes the excellent down. When the convertible excellent is up, the roof rails provide multiplied physique stiffness and reduce noise and wind intrusion.
The 4 doors are power-operated and hinged on the front and rear pillars, opening on the middle pillar. Articulating hinge mechanisms permit the doorways to open extensive. Recessed rockers and door sills increase access to the motor vehicle. And, the rear seat folds down.
A hybrid hybrid. At Daimler-Chrysler, dressmaker's are the use of Visio and CATIA to create their futuristic concoctions. And as soon as once again, business items are using one of the design concerns.
Chrysler's concept vehicles additionally handle the should raise fuel effectivity or look at alternative operating methods. The castle blends a game sedan with an SUV and mixes in a futuristic efficiency powertrain.
"The citadel is a hybrid-hybrid, a brand new breed of crossover vehicle. It gives the using passion of the Chrysler 300M with ample cargo room," says Neil Walling, vice president of advanced design and exterior gigantic-motor vehicle, small automobile, and minivan. while fortress is a hybrid among market segments, it is additionally a hybrid of powertrains; it really is, it draws from two distinctive sources.
"or not it's a performance hybrid," explains Bernard Robertson, senior vice president, engineering applied sciences. "The fortress gives you V-8 power with V-6 fuel economic system." A gas engine propels the rear wheels and electrical energy drives the entrance wheels. "We use the hybrid idea to get well energy continuously lost when braking, while proposing all-wheel -pressure."
The rear wheels movement by means of a 3.5l V-6 and the entrance wheels receive extra power from Siemens car electric motors, which were used on electric powered motors, comparable to the sidestep Caravan/Plymouth Voyager EPIC electric powered minivan. The V-6 generates 253 hp and the electric powered motors add one other 70 hp.
different highlights of the fortress encompass twin-vigor sliding rear doors and a retracting cargo door that slides below the ground. The B pillar moves with the rear door as it opens to maximize accessibility.
The fortress has 2 inches greater ground clearance and is three inches taller than the Chrysler Concorde. It has 20 x 3 feet of storage room, as in comparison to the 18.7 x 3 toes. for the Concorde.
Instrument panel design is influenced by using excessive-conclusion activities watches such as Chronoswiss and Blancpain. Hand-sculpted chrome is used for the indices on the gauges face. different elements consist of handmade chrome bevels around the odometer and clock--which includes into the steerage wheel, door-manage modules, pedals, and the folding tray desk on the bottom of the entrance seats.
As they around the corner to the millenium, automobile design races full speed ahead. cutting-edge roads are the music for a new breed of cars. Which concepts will move ahead and what else will emerge? it truly is within the arms of the designers, the vendors, and the tools--we will ought to wait and spot.additionally...
here's every other thought vehicles introduced on the Detroit Auto show:
Ford: Thunderbird, Blackwoodthis is only 1 instance of how GM is moving design. one other is a new spin on modern-day convertible.
"A no-compromise automobile." this is how the Buick Cielo's design team described this thought, which they are saying provides the comfort of a sedan with the with the open-air enjoyment of a convertible.
This theory is designed from a primarily math-primarily based technique that includes huge use of computers, 3D modeling, computing device sketches, rendering, and creation of a foam, not clay, mannequin.
This 4-door convertible seats five and lines a three.8l supercharged V6 engine with four-speed auto transmission.
The Cielo aspects extensive-opening doors, a twin head-up display, voice-activated methods (equivalent to a retractable roof it's both voice or button operated), air luggage (hooked up within the roof rails), and a shift-by-wire roof (a sunroof that opens to varying levels). The ignition is keyless.
Cielo's two roof rails run between the front of the passenger compartment and the rear end, strengthening the ordinary physique and enabling use of three difficult roof panels that slide into the trunk when the motive force wishes the desirable down. When the convertible desirable is up, the roof rails provide elevated body stiffness and in the reduction of noise and wind intrusion.
The 4 doorways are power-operated and hinged at the entrance and rear pillars, opening at the core pillar. Articulating hinge mechanisms enable the doors to open vast. Recessed rockers and door sills Improve entry to the vehicle. And, the rear seat folds down.Flex ring rinses out washer abuses
Newton, IA--Maytag Corp.'s washing machines are noted for their reliability and maintenance-free efficiency. hence, it appeared best natural for the great-aware engineers at Maytag to group up with a product building group at a huge producer of elastomers for concepts on a way to make its washers even enhanced.
The assignment: construct a brand new multi-cavity device for a flex ring that makes up part of the torque-sensitive mechanism within the agitator of the vertical washer. The previous cloth did not provide the excessive stiffness traits needed to adjust the amount of agitation for various load sizes. youngsters, no general-grade thermoplastic polyurethanes Maytag established fulfilled the need.
Maytag engineers conferred with personnel from Pella Plastics (Pella, IA), the half's producer, and with BF Goodrich (Cleveland) building engineers to come up with an answer. The crew right now recognized the houses crucial to meet both method and performance pursuits of the brand new flex-ring design. Then product development engineers at BFGoodrich's thought core became these requirements into fact with the aid of developing Estane(R) 58151, a high-stiffness, durable, 70 Shore D thermoplastic polyurethane that offered miraculous hydrolytic stability.gadget cools off computing device processor
West Columbia, SC--quick processor speeds generate warmth, which means whatever thing's bought to cool every little thing off. it really is why Compaq turned to KryoTech Inc. to provide the cooling equipment for the KryoTech/Digital 767 personal SupercomputerTM, which runs at 767 MHz.
KryoTech's patented -40C cooling gadget become developed certainly for use with the Alpha pc, in accordance with Scott Spears, product advertising manager for KryoTech. "each and every cooling gadget is certainly designed for use with the certain processor," he says.
The Alpha computing device works with mechanical, CAD, or CAE functions. It additionally has been utilized in research and in custom design applications. "americans use it after they need as tons quantity-crunching energy as they can get out of one processor," Spears notes.
The cooling equipment is a typical vapor-phase refrigeration one. It uses a freon choice coolant, which is environmentally friendly. The device pumps liquid coolant to the evaporator, which is involved with the workstation CPU inner the KryoCavity.
The KryoCavity is a hermetically sealed and peculiarly insulated device that holds the CPU and continues the electrical connection with the motherboard. A power decrease inner the evaporator causes the liquid coolant to become a gas, and this part exchange pulls the warmth off the CPU, Spears says.
KryoTech got here to Compaq, which was then Digital, with the concept for a thermal cooling answer. "We work on the premise that as chip expertise progresses, chip size does not trade, but chip energy does, and they produce more and more heat," Spears says.
"energetic cooling programs like they promote no longer handiest dissipate the warmth but aid the person get greater energy out of the chip."
The cooling device goes to -40C, and at that temperature, the device provides a 30% boost in processor pace. KryoTech is working on a equipment that gets colder than that. "At -120C, you double the velocity of the processor," Spears says.
individuals at domestic occasionally also overclock their computer systems, tuning their motherboards and turning up the speed of their processors. This gives the consumer extra power and velocity, however generates excessive heat, which can cause hurt to the computer. "They use any and each capacity they can to cool them off, together with putting their total desktop in the refrigerator," Spears says. "we've got heard about all forms of unusual methods."Elastomer prevents system illness
Fremont, CA--HTM technology Corp. believes staying forward within the desktop industry calls for only the ultimate manufacturing innovations and expertise. that's why, as a number one provider of skinny-film disks for top-potential disk drives in PCs, community servers, and workstations, the company must handle infection all through processing. it's additionally an enormous reason why HMT these days replaced fitted fluorocarbon-covered elastomer seals with perfluoroelastomer elements in its electro-less nickel plating production machine.
provided by way of Pan Pacific supply Co. (harmony, CA), the elements, made by way of DuPont Dow Elastomers (Wilmington, DE) from Kalrez(R), have saved HMT an estimated $770,000 per year in decreased downtime, while enhancing protection on the construction line.
Kalrez combines the sealing drive and resilience of an elastomer with the chemical inertness and thermal balance of Teflon(R) fluorocarbon resin to create an exceptionally durable seal that may survive beneath extreme caustic conditions. It consists of no active hydrogen atoms in its polymer backbone, giving it the capacity to resist a wide range of chemical compounds, yet continue to be thermally stable at temperatures as excessive as 600F.
in the electro-less nickel plating technique, nitric acid (40% at 125F) removes nickel construct-up on the aspect of the plating tank. For HMT, the harsh chemical atmosphere disintegrated prior to now installed fluorocarbon O-rings used in quite a lot of valves and fittings. outcome: The business had to manually alternate the seals at the least once a month.
HMT replaced the fluorocarbon O-rings with Kalrez in one of its seven plating tanks in December 1995. After a a hit two-yr trial-and-error campaign, the business equipped the six remaining tanks with the material.
"Degrading of the fluorocarbon O-rings would start almost immediately, resulting in equipment contamination, acid leaks, and creation loss," says Brian McIntyre, HMT's gadget engineering supervisor. "due to the fact that the change to Kalrez seals, we're replacing seals about once each two years."mobile phones face up to difficult environments
Nashville, TN--Given survey consequences displaying that individuals at work spend as a minimum two and a half hours a day far from their desks--costing corporations over $3 billion a yr--Northern Telecom (Nortel) determined to enhance a more-long lasting, less-expensive instant phone. The outcome: the companion C3050 phone with a tricky mobilephone-protecting accessory manufactured from thermoplastic rubber.
The associate mobile collection allows mobile, wireless communications in the workplace, expanding worker productiveness, enhancing consumer carrier, and cutting back fees. no matter if someone is mountaineering a ladder or just in an workplace down the corridor, the cell's custom-designed Rugged Protector accent allows the user to clip the cell on for superior comfort and freedom of circulate.
Design Workshop (Ottawa, Canada) turned into the commercial designer for the holster of Nortel's previous partner C3020 collection of telephones, designed essentially for office use. the brand new phone series mandatory to face up to the more difficult circumstances of an industrial atmosphere, so Nortel asked Design Workshop to incorporate the Rugged Protector in the new fashions.
In flip, Design Workshop reduced in size the molding process to ITW Plastiglide (Toronto, Canada), which had the insert molding and tooling expertise vital for the accessory's design. The utility offered both agencies with a problem: Make an problematic, yet protective and sturdy cowl that enables the user to function the mobilephone whereas nevertheless in its holster.
"The C3050 become extra advanced and contained more delicate components than the previous collection," notes John Tutton, companion, Design Workshop. "We necessary to make sure they chosen the right grade of cloth that might meet crucial performance and visible necessities."
Tutton used Santoprene(R) rubber, supplied by using superior Elastomer systems L.P. (AES, Akron, OH) as the base cloth for trying out and comparing other skills fabric candidates. The fabric they sought had to have the potential to kind the telephone's problematic elements, face up to abrasion, and still supply sufficient impact protection.
"We went through a long list of thermoplastic elastomers when making an attempt to get a hold of the correct material, starting with Santoprene, given that its properties made it the suitable contender from the beginning," Tutton recollects. "After conducting the assessments, they ended up deciding upon a standard seventy five shore A grade of Santoprene because the most useful fabric."faster QUERIES

Chicago--From March 15 through 18, engineers will have the chance to adventure "the usa's #1 supply for contemporary Industrial options" at countrywide Manufacturing Week. The show, which drew greater than 60,000 attendees closing 12 months, is backed by using the countrywide Assn. of manufacturers.
Manufacturing Week carries the countrywide commercial enterprise IT, countrywide Industrial Automation, national Plant Engineering MRO and management, and the national Design Engineering shows and conferences.
a brand new development this year in the country wide Design Engineering part of country wide Manufacturing Week is the action hall, which is a whole hall committed to motion-handle items.
closing yr, 2,100 exhibitors had been on the show flooring. Two groups who're returning this year are Cutler-Hammer (Cleveland, OH) and Intergraph computing device systems (Huntsville, AL).
Cutler-Hammer will be celebrating its 5-yr anniversary as a company, and should be showing "most suitable-in-classification solutions, and the way they may be taking them into the longer term and impacting manufacturing strategies," says Paul address, advertising communications manager. The stage reveal, which featured song and dancers that transitioned right into a speaker final 12 months, will return, and will be "greater and more advantageous, informational and entertaining," address adds.
"we're going to blow all and sundry away," he says. "The show is essential to us, and they suppose lucky to be part of it. you'll must see it to accept as true with it."
Cutler-Hammer will also be showcasing several new items, including the SM series photoelectric sensors. The collection makes use of a microprocessor-controlled equipment known as TargetLockTM to support users pace up the setting up manner and increase sensor reliability, the enterprise says.
one other product Cutler-Hammer might be showing in its booth at country wide Manufacturing Week is the SV9000 line of drives, which are available from 0.seventy five to 1,100 hp and 200 to 690V. The drives are constant across all body sizes, tackle says.
in the Intergraph computer techniques booth, look forward to the existing Intel/home windows NT-based TDZ-2000 visible workstations centered at MCAD experts. Intergraph will also demonstrate loads of mechanical CAD applications, together with seasoned/ENGINEER and SolidWorks, in line with Marla Robinson, media relations supervisor for Intergraph. The TDZ-2000 workstations feature extreme(R) 3D Wildcat images, which, Robinson provides, are the quickest photographs on windows NT.

Palo Alto, CA--Hewlett-Packard has broken a memory bottleneck with its HP Visualize model C360 workstation, which it touts because the world's quickest computing device notebook. according to HP's new 367-MHz PA-8500 sixty four-bit microprocessor, the C360 achieves performance specs of 26.0 SPECint95 and 28.1 SPECfp95, as measured by way of HP.
Its performance numbers are significantly enhanced than those of its predecessors, the C200 and C240, which use previous versions of the PA-8000 household. efficiency on mechanical design functions is up to 77% faster, says Barry Crume, product advertising manager for HP's computing device division. however the most effective hardware change is that the C360 has its simple (or first-degree) cache memory built-in on the PA-8500, and the C200 and C240 basic caches are the motherboard. other than that, the three machines are very nearly similar.
HP engineers have been able to integrate 1.5 Mbytes of basic cache on the PA-8500 chip through the use of a 0.25-micron manufacturing process as an alternative of 0.33 micron. (The smaller geometry also expanded the chip's frequency.)
other merits of on-chip basic cache include:
Bus between on-chip basic cache and CPU runs at CPU clock fee (367 MHz for PA-8500), which is lots faster than for off-chip cache.
The C360 was designed for engineers doing computationally intensive work. A C360 with VISUALIZE-fx2 portraits, 256 Mbytes of RAM, a four-Gbyte tough disk, and 21-inch display screen fees $24,500.past detection, less difficult cure Rick DeMeis associate Editor
Skaneateles Falls, big apple--an instantaneous influence of scientific equipment company Welch Allyn's ongoing schooling ambiance is the technology in its frequency-doubling visible container Analyzer (see DN 1/18/98). here, a medical products Operation advanced expertise supervisor attended a convention and met the Australian researcher who formulated the concept. The company introduced the expertise in condo for development in conjunction with institution and business design companions. extensive, focused working towards in electromagnetic interference (EMI) and susceptibility brought one engineer as much as pace for his element of the design. at last the product turned into carried out and brought by means of the enterprise's pass-practical teams.
The visual field Analyzer looks at eye function for advanced warning of glaucoma. it is greater sensitive and provides fewer false positives and negatives than the standard strategies of eye-force dimension, such because the "air puff." up to now, high accuracy became feasible only the usage of equipment costing 4 instances as tons (as much as $25,000), the enterprise asserts. testing would take 15 min/eye as opposed to 45 sec now.
The affected person looks at a sequence of bars that vary sinusoidally between mild and darkish. Between 25-28 Hz, a group of retinal nerve cells, that turn up to be the primary degraded by using glaucoma, produce an optical phantasm of twice as many bars. deciding upon the distinction stage where the bars are just barely visible correlates to quite a lot of eye ailments for past detection and less demanding remedies.
