Patent number: 8610622Abstract: An aimed or aiming firearm can be detected before it is able to shoot. Wideband radar signals can be used to identify the barrel of a firearm when the radar antenna and barrel are aiming at or near each other. Signal processing correlates reflected signals to the characteristics of specific firearms of interest, and alerts the user when someone is pointing such a firearm at them. Modern wideband radar systems with fast signal processing speed can enable real-time detection of firearm threats in crowded and cluttered areas before they shoot, which has never before been possible. Related systems, apparatus, methods, and articles are also described.Type: GrantFiled: October 25, 2011Date of Patent: December 17, 2013Assignee: Flex Force Enterprises LLCInventors: Jacob Ryan Sullivan, Daniel J.

Patent number: 7355492Abstract: The inventions presented herein provide a electronically controlled phase shifters that incorporate analog and digital phase shift architectures in a novel manner that realizes the best advantages of each architecture. This combination of complementary phase shift architectures provides the high-performance and low loss characteristics of switched digital phase shift architectures with the high resolution and precision of continuous analog phase shift architectures. The circuit embodiments are electronically controlled, which simplifies implementation of what is a complex circuit. The analog phase shift elements comprise electronically-tuned varactors, which provide fine resolution and enables the incorporation of active compensation for manufacturing variation before use or for environmental conditions during use.Type: GrantFiled: March 31, 2005Date of Patent: April 8, 2008Assignee: Xcom WirelessInventors: Daniel J.

Publication number: 20040207498Abstract: This invention is a new type of relay that incorporates the functional combination of multimorph actuator elements with electrostatic state holding mechanisms in the development of a micromachined switching device. This combination of elements provides the benefits of high-force multimorph actuators with those of zero-power electrostatic capacitive latching in microfabricated relays with high reliability and low power consumption. The operation of the relay invention allows for several stable states for the device: a passive state using no power, an active state driving the multimorph actuator with some power, and a latched state electrostatically holding the switch state requiring essentially no power. Multimorph actuators covered by this invention include piezoelectric, thermal, and buckling multimorph actuation mechanisms. These devices use one or more sets of actuator armatures in cantilever or fixed-beam configurations, and use one or more sets of electrostatic latch electrodes for state holding.Type: ApplicationFiled: December 19, 2003Publication date: October 21, 2004Applicant: XCOM Wireless, Inc.Inventors: Daniel J.

Patent number: 6667245Abstract: A microelectromechanical (MEM) switch is fabricated inexpensively by using processing steps which are standard for fabricating multiple metal layer integrated circuits, such as CMOS. The exact steps may be adjusted to be compatible with the process of a particular foundry, resulting in a device which is both low cost and readily integrable with other circuits. The processing steps include making contacts for the MEM switch from metal plugs which are ordinarily used as vias to connect metal layers which are separated by a dielectric layer. Such contact vias are formed on either side of a sacrificial metallization area, and then the interconnect metallization is removed from between the contact vias, leaving them separated. Dielectric surrounding the contacts is etched back so that they protrude toward each other. Thus, when the contacts are moved toward each other by actuating the MEM switch, they connect firmly without obstruction.Type: GrantFiled: December 13, 2001Date of Patent: December 23, 2003Assignee: HRL Laboratories, LLCInventors: Lap-Wai Chow, Tsung-Yuan Hsu, Daniel J.

Patent number: 6331257Abstract: Methods for the design and fabrication of micro-electro-mechanical switches are disclosed. Two different switch designs with three different switch fabrication techniques are presented for a total of six switch structures. Each switch has a multiple-layer armature with a suspended biasing electrode and a conducting transmission line affixed to the structural layer of the armature. A conducting dimple is connected to the conducting line to provide a reliable region of contact for the switch. The switch is fabricated using silicon nitride as the armature structural layer and silicon dioxide as the sacrificial layer supporting the armature during fabrication. Hydrofluoric acid is used to remove the silicon dioxide layer with post-processing in a critical point dryer to increase yield.Type: GrantFiled: November 30, 1999Date of Patent: December 18, 2001Assignee: Hughes Electronics CorporationInventors: Robert Y.
