摘要:
A method of target discrimination and identification, on a computer including a processing unit and a non-volatile storage device, from a radar signal having a plurality of radar return signals, is presented. The method includes: modeling, on the computer, the radar return signals by linear prediction to produce linear prediction equations; solving, on the computer, the linear prediction equations by the Burg algorithm to produce linear prediction coefficients for a linear prediction coefficient polynomial; computing, on the computer, roots of the linear prediction coefficient polynomial to produce scattering modes; computing, on the computer, a distance of each of the scattering modes to a unit circle; computing, on the computer, a complex envelope for each mode of the scattering modes; and selecting, on the computer, target scattering modes from among the scattering modes based on the distance of the mode to the unit circle and the complex envelope of the mode.

A distributed test architecture of transmitting boundary scan Test Access Port (TAP_signals over a serial channel is disclosed. The architecture facilitates the system testing and remote field update of distributed base stations in a wireless network. The distributed test architecture enables system testing as if the distributed units are on a backplane within the same chassis by creating a plurality of logical connections between the distributed unit and the test bus using a single bit fiber line and a five bit TAP test bus.

A liquid crystal (LC) lightvalve comprising a twisted nematic LC layer whose molecules are aligned with pixel edges at the mirror backplane, thereby providing improved contrast and efficiency, and reduced visibility of post spacers in black state. The present invention is directed to an LC structure wherein the backplane is rubbed in a direction rectilinear with pixel edges. The LC layer is given the same twist rotation and birefringence as in the conventional TN lightvalve. Polarization control is maintained by illuminating the lightvalve with light whose polarization is rotated by the twist angle relative to the x,y, pixel axes, and by collecting the orthogonally polarized component of the reflected light. The lightvalve top glass is thus rubbed in a direction which is rotated by the twist angle from the horizontal or vertical direction at which the backplane is rubbed.

The baseband unit includes a first Radio Frequency (RF) coverage unit, a second RF coverage unit, and an interface unit. The first RF coverage unit is configured to communicate with RF devices according to a first communication protocol. The second RF coverage unit is configured to communicate with the RF devices according to a second communication protocol different than the first communication protocol. Further, the interface unit is configured to selectively interface one of the first and second coverage units with the RF devices.
摘要:
A video processing method and system for generating a foveated video display with sections having different resolutions uses a network channel for communicating video images having video sections of different resolutions, and includes a video transmission system for processing and transmitting the received video images over the network channel. The system assigns a larger portion of the network channel's bandwidth to a video section with higher resolution. Further, the system includes a video receiving system for receiving and seamlessly combining the first and second video sections of different resolutions to form an output video image on a display device, and a control unit for sending one or more video control parameters to the video transmission system to control capturing, transmitting and processing of the video images.

An improved system and method for pen-based handwritten and keystroke data input into a computer system is disclosed. The system and method receives pen-based data entry from multiple related input boxes within a handwriting area on a digitizer pad. Thread-based processing allows each input box or group of input boxes to be separately evaluated, providing for continuous character recognition. Character strokes entered into each input box or group of input boxes are saved and interpreted together to allow more complete recognition of naturally written characters. Improvements on keyboard layouts are also disclosed.
