Abstract: Described here is an integrated control system for crash-rated barriers and bollards, barrier products and software which will improve the operational safety characteristics of the barriers and ancillary equipment; identify potential security breaches of the barrier operating system, and predict potential failures in the system. Crash rated barriers and bollards are used to prevent a vehicle attempting to penetrate the secure perimeter of a facility with malicious intent. Installation and operation of crash rated barriers is utilized to protect both government, commercial and private facilities against such threats. Simultaneously it allows ingress and egress to the facility resulting in the end user having to determine tradeoffs for security versus safety. The barriers described here are designed and certified to withstand attacks from heavy vehicles traveling at high rates of speed.

Abstract: A heat engine includes a turbine (10), compressor (20), heat pump (30) and combustion source (40) and uses heated and compressed air as a motive fluid in an open Brayton cycle. In the process of the invention, the compressor pressurizes air (21) from the environment. A closed-cycle heat pump (30), having a high-temperature condensation side (33) and a low-temperature evaporation side (35), increases the energy in the compressed air through heat exchange with the high-temperature condensation side (33) of the heat pump. Upon heating in a constant pressure process, the motive fluid is expanded through the turbine (10). The combustion source (40), which is isolated from the motive fluid, further heats the low-temperature evaporation side (35) of the heat pump.

Abstract: A method of electronically signing a document includes initializing a user, including generating an asymmetric key pair including a private signing key and a public signing key, and storing the private signing key and the public signing key; and providing an electronic signature, including receiving document data corresponding to at least one selected portion of the document, binding the stored private signing key and the document data to create an electronic signature, and providing the electronic signature for a recipient.

Abstract: A system provides cryptographic processing of input data on a parallel processor array that includes plural processors. A format filter extracts control and main data from the input data. A control unit receives the control data, and based on the control data, forwards control and cryptographic parameters to the processors. A first distributor distributes to each processor at least a portion of the main data. A second distributor receives output information from each processor, and based thereon, generates output data. Each processor generates output information based on the control and cryptographic parameters. The output data is a cryptographic processing result.
