Abstract: Communications systems containing a Push-To-Talk (PTT) device containing an auxiliary audio component are described in this application. The communication system can be worn by an operator and comprises a radio, a headset, a communication device (such as a cellular phone), and a Push-To-Talk (PTT) device modified with an auxiliary audio component capable of overriding or controlling communication between the headset and the communication device when a signal is transmitted to or received from the radio. The modified PTT device allows the operator of the system when wearing the headset to use the communication device (i.e., cellular phone) without the fear of interrupting communication with the radio. Other embodiments are described.

Abstract: An interchangeable cumberbund with integrated wiring to allow for connecting a variety of electronic devices for an intended purpose or mission and exchanging a configured garment for another. The reconfigurable cumberbund allows for multiple quick-disconnect cable harnesses to be weaved into the cumberbund which enables rapid and convenient removal of hardware that incorporates all I/O to a computer. The reconfigurable cumberbund connected to a wearable tactical vest containing a mobile ultra-rugged personal computer is the essential combination that allows hands-free use by the user.

Abstract: A personal computer and methods of reconfiguration are described. An implementation of a personal computer may comprise a processor portion running a diagnostic application. A field programmable gate array in communication with the processor portion may be provided. A configurable non-volatile computer memory in communication with the field programmable gate array and wherein the field programmable gate array is programmed to reconfigure the non-volatile computer memory may be provided. Methods of reconfiguration of a personal computer are provided.

Abstract: A guidance electronics unit is provided for an explosively-launched vehicle, e.g., a projectile or missile, comprising a plurality of circuit card assemblies, each circuit card assembly containing a plurality of electronic components and interconnections, each circuit card assembly maintained in a housing and spaced apart. All spaces surrounding each circuit card assembly are filled with a granular material to provide support for each circuit card assembly during explosive launch. Further, a method for supporting circuit card assemblies in the guidance electronics unit is provided. The problem of enabling guidance electronics to survive the large loads encountered during an explosive launch out of a gun, such as a howitzer, or missile launch tube is thereby solved.
