Patent number: 7314004Abstract: The present invention is directed to a system and a method for accurately locating a penetrating-type weapon within a shelter for detonation at a desired target site. The method includes detecting a deceleration threshold event indicative of the penetrating weapon impacting and traversing a layer of shelter having certain material or structural characteristics (e.g., a “hard” or a “thick” layer). A delayed detonation program or process is enabled upon detection of the threshold event. For example, a delayed detonation program or process may include layer counting, void counting, or a combination of layer and void counting until the desired number of layers (and/or voids) of a shelter has been detected, at which time the weapon may be detonated. Any deceleration events that occur prior to the deceleration threshold event are ignored to minimize the potential failure of detecting specific types of layers including certain types of “soft” or “thin” layers.Type: GrantFiled: June 9, 2005Date of Patent: January 1, 2008Assignee: Alliant Techsystems Inc.Inventors: Bradley M. Biggs, William A. Friedrich

Patent number: 7197982Abstract: The present invention is directed to a system and a method for accurately locating a penetrating-type weapon within a shelter for detonation at a desired target site. The method includes reliably and accurately detecting thin layers of a shelter by use of a weapon frequency induced by a vibration in a portion of the weapon. The weapon frequency is detected and at least one harmonic frequency of the weapon frequency is analyzed to determine whether a deceleration threshold event has occurred. In one embodiment, the harmonic frequency may be compared to a target frequency which is associated with the deceleration of the weapon during penetration of a layer of media. In another embodiment multiple weapon frequencies may be detected, analyzed, or compared to detect the penetration of a layer of media.Type: GrantFiled: June 8, 2005Date of Patent: April 3, 2007Assignee: Alliant Techsystems Inc.Inventor: Bradley M.

Patent number: 5573428Abstract: A low profile hermetic electrical connector includes a conductive layer with opposite first and second conductive layer surfaces. An inner electrical isolation layer is coupled between the first conductive layer surface and a first contact and an outer electrical isolation layer is coupled between the second conductive layer surface and a second contact. A contact interconnector electrically couples the first contact and the second contact through the inner electrical isolation layer, the conductive layer, and the outer electrical isolation layer without electrically contacting the conductive layer, creating a serpentine, low flow path for vapor through the adhesive layers. In a hermetic electrical cable end connector, the first contact is electrically coupled to a first conductor through a first interconnector and a second contact is electrically coupled to a second conductor through a second interconnector. Two additional electrical isolation layers are required.Type: GrantFiled: June 24, 1994Date of Patent: November 12, 1996Assignee: Motorola, Inc.Inventors: Bradley M. Biggs, Christopher F. Norton, Louis P. Farace

Patent number: 5454321Abstract: An electronic safe and arming device includes an enclosure (11) which has a circuit (16) for enabling a detonator (26). The circuit (16) has a sealed tube switch (17) which is pressurized with a gas mixture. The enclosure (11) is pressurized with substantially the same gas mixture (19) and pressure as in the tube switch (17). Safe and arm electronics control (20) triggering the tube switch (17) to set off a detonator (26) which in turn sets off an explosive charge. As a result the present safe and arming device is single fault tolerant.Type: GrantFiled: October 17, 1994Date of Patent: October 3, 1995Inventors: Bradley M. Biggs, Steve M. Curtis, Robert H.

Patent number: 4633779Abstract: An oscillator supplies clock pulses to a counter which also has a preselected time applied thereto and arming means are initiated when the count reaches the preselected time. Checking means are utilized throughout the circuitry to provide failsafe checking of each critical circuit with the arming circuit being deactivated if an error is detected. The entire circuit is incorporated in a single IC for energy and space conservation.Type: GrantFiled: June 29, 1984Date of Patent: January 6, 1987Assignee: Motorola, Inc.Inventors: Bradley M.
