Major advances in microelectronic and micromechanical components have been made in recent years. the offeror has developed a preliminary design for a very low-cost accelerometer that combines the sensor, sense amplifier and a/d converter on a single chip. analyses indicate that the design offers a… More

Major advances in micromechanical components in recent years have made possible new design approaches for a safe and arm device. developments in custom intergrated circuits now allows the design of a "subsystem on a chip". recent advances have also been made in micromechanical devices, including the… More

Kinetic-kill vehicles will need guidance, navigation and control systems capable of operating after long periods of time in a hostile radiation environment. components resistant to burnout caused by exposure to intense levels of radiation must also be small, light weight and low-cost. suitable… More

The purpose of an air flight sensor subsystem is to detect the signature of flight conditions after a projectile has been safely fired. this information, when combined with other characteristics of projectile firing, such as acceleration, provides positive indication when it is safe to arm the… More

Mechanical g-switches are presently available that sense when the acceleration exceeds a specified value. contact resistance is a problem even with newly fabricated mechanical g-switches. mechanical contacts are also subject to switch bounce and damage during the initial shock of impact. silicon… More

The safety of the flying plate detonator is key to its use in in-line fuzes. the main advantage of the flying plate detonator is one of its advantages from a safety viewpoint; a substantial amount of electrical energy, on the order of a joule, must be delivered to the bridge in less than a… More

The fluxgate magnetometer has evolved of the last 50 years into a sensitive device used in strapdown magnetic compasses. however, the fluxgate magnetometer is relatively complex, requiring a large number of parts, including ferromagnetics. its reliability makes it less desirable for use in future… More

Although conventional mass-spring retard sensors are inexpensive, their poor reliability usually requires the use of two devices in parallel to assure switch closure. the use of two devices, however, has an adverse affect on s&a safety. g-switches used as retard sensors in the fmu-139 bomb fuze are… More

Current microfuses for fascam mines, whose design is similar to miniature detonators or squibs, have reliability problems. this results in mines which self-destruct early, reducing minefield effectiveness, or late, endangering friendly troops moving into the area. miniature detonators using thin… More

Crush sensors and probes used in inexpensive missiles as contact devices are easily damaged by handling or anti-missile defenses. piezoelectric accelerometer contact fuzes with fixed thresholds have trouble detecting a "soft" impact with an aircraft-s aluminum skin in the presence of acceleration… More

Silicon Designs has developed a low-power, miniature accelerometer technology that combines micromachining and integrated circuit in a single package. These units weigh less than 1 gram and consume about 5 milliwatts of power and are designed for use in smart systems. The proposed project is an… More

Silicon Designs has developed a low G accelerometer technology using micromachined sense elements. In this project we propose to develop a family of high-G, shock survivable accelerometers for hard target fuzing. Our goal is to develop sense elements that will withstand the 100,000 g pea… More

Not Available The proposed research will investigate the use of autonomous software agents to observe activities within the design process. These agents will be trained to monitor the transactions among and between design teams to establish a standard or accepted practice. This standard will be… More

"In the past five years, SDI has developed low energy EFI detonators, built with MEMS processes, that have about half the firing voltage of previous designs. These detonators are in production and are being used in about six weapon systems.This reduction in firing voltage makes it possible to use… More
