Abstract: A method and apparatus is disclosed for efficiently encoding data representing a video image, thereby reducing the amount of data that must be transferred to a decoder. The method includes transforming data sets utilizing a tensor product wavelet transform which is capable of transmitting remainders from one subband to another. Collections of subbands, in macro-block form, are weighted, detected, and ranked enabling prioritization of the transformed data. A motion compensation technique is performed on the subband data producing motion vectors and prediction errors which are positionally encoded into bit stream packets for transmittal to the decoder. Subband macro-blocks and subband blocks which are equal to zero are identified as such in the bit stream packets to further reduce the amount of data that must be transferred to the decoder.

The entangled photon pairs are also selected to have an energy distribution between the signal photon and the idler photon to substantially decrease an associated random two-photon absorption cross section of the target medium. The entangled photon pairs are directed to the target medium, and at least one entangled-photon pair being absorbed by the target medium is detected.

Abstract: A portable computing device, including a latch apparatus and system, may include a rotatable high wear plastic oversnapping arm, a pivot portion on the portable computing device, and an enclosure door with a geometric mating feature. The oversnapping arm may be configured to rotate 90° about the pivot portion to snap over the geometric mating feature and secure the enclosure door in a closed, latched position. As the oversnapping arm is rotated downward, its progress may be frictionally impeded by the geometric mating feature. Applying downward pressure on the oversnapping arm towards the physical interference may cause the oversnapping arm to bend over the interfering feature and snap into a closed, geometrically interlocked position. In the closed, latched position, the oversnapping arm may apply a positive pressure against the enclosure door. The positive pressure on the enclosure door increases the environmental sealing capabilities by putting additional pressure on the existing environmental seal.

Abstract: A telemetry system is described in which a plurality of channels are coupled to a bus. A control subsystem controls the channels so that one of the channels presents to the bus during its designated time period a channel characteristic. The control subsystem interrogates in the analog domain each of the channels during its designated time period, and forms a signal representative of the channel characteristic. The control subsystem may combine one or more of the signals into a digital packet, and transmit the same via transceiver over a wireless network. The channels may be contained within a submersible enclosure and displaced at intervals along the bus, thereby forming an array for monitoring waterborne threats. The array may lie along an ocean floor, may be towed by a marine vehicle, or may suspended from a deployable buoy containing the control subsystem, transceiver, and a remote power source. The array may further comprise a defensive countermeasure deployable responsive to detecting a threat.

Abstract: Systems and methods for generating high power, wideband microwave radiation pulses. A pulse generating device includes a capacitor as a primary electric energy store, a source of mechanical or chemical energy for modifying the capacitance of the capacitor, which then connects to a transmission line or pulse forming line (PFL) with many times increased electromagnetic energy, a switch and a broadband radiating element such as an antenna. A high voltage pulse and accordingly a high amount of electromagnetic energy is formed owing to decreasing the capacitance of an initially charged capacitor by dynamically changing a configuration of capacitor electrodes using mechanical work. The final configuration forms a transmission line, with the voltage and electric energy increased by the ratio of initial capacitance to final capacitance when the charge on the modifying capacitor is conserved.
