Patent number: 6595102Abstract: A counter-terrorism, reactive personnel protection system which detects the presence of a destructive object as it approaches a designated personnel target along an intersecting path. Before impact, an air bag is rapidly inflated and interposed between the destructive object and the target so as to provide a protective barrier. The air bag is constructed from polyethylene material or other anti-ballistic materials, and serves to halt or redirect the detected destructive force of the object and thereby protect the designated target from attack.Type: GrantFiled: May 16, 2002Date of Patent: July 22, 2003Assignee: Southwest Research InstituteInventors: David J.

Patent number: 6298787Abstract: A non-lethal kinetic energy system comprises a propellant means in mechanical communication with the combination of a personnel target proximity detection means, an air bag carried in an uninflated condition, and a means to inflate the air bag responsive to a signal provided by the proximity detection means as the system approaches a personnel target. The system may include a delay element for selective adjustment of the kinetic energy delivered to the personnel target. The invention also provides a method of operating a non-lethal kinetic energy system comprising the steps of deploying the system toward a personnel target, sensing the proximity of the target, sending a signal to an air bag inflation means at a predetermined distance from the target, and inflating the air bag before impacting the target.Type: GrantFiled: October 5, 1999Date of Patent: October 9, 2001Assignee: Southwest Research InstituteInventor: Thomas J.

Patent number: 5542118Abstract: A remote, unpowered passive transmitter has a tank circuit, a coil and capacitor. The capacitor is variable to vary the frequency of the tank. This is coupled to a receiver having a hybrid splitter. With four ports, two balanced, opposing ports connect to two lines terminating in line impedance. The tank couples into one of the two line so that a difference signal is formed and output. Line loading forms a signal indicating tank frequency.Type: GrantFiled: September 13, 1994Date of Patent: July 30, 1996Inventor: Thomas J. Warnagiris

Patent number: 5367310Abstract: A system for switching an antenna formed of multiple connected segments is set forth. The various segments are connected together by a switch means having, in the preferred embodiment, one or more FETs; a gate controlled terminal is connected with a bias circuit which is biased on or off by a bias circuit triggered to switch by light. The light is coupled through an optical fiber which directs light onto a portion of the bias circuit to cause operation. The bias circuit preferably includes a photo voltaic cell.Type: GrantFiled: October 11, 1991Date of Patent: November 22, 1994Assignee: Southwest Research InstituteInventor: Thomas J. Warnagiris

Patent number: 4903324Abstract: The communications system of the present invention defines a complete feedback path consisting of first and second transceivers and an appropriate signal path. Each transceiver comprises a detector and a signal source capable of generating a signal at one of two frequencies. The detector in each of the transceivers is a two state device tuned to respond only to a predetermined desired difference frequency. If the desired difference frequency signal is present, the detector provides and output signal in a first state; if the desired difference signal is not present, the detector provides an output signal which is in a second state. The signal source can be a voltage controlled oscillator, a pair of single frequency oscillators, a synthesizer, or any signal source capable of being electrically switched between two frequencies. Data can be exchanged between the transceiver pair only when the desired difference frequency is present.Type: GrantFiled: February 1, 1988Date of Patent: February 20, 1990Assignee: Colin Electronics Co., Ltd.Inventor: Thomas J. Warnagiris
