Abstract: The objective of this patent is to develop new signal processing algorithms for a wide-band circular electronically scanned array (CESA) or a wideband linear electronically scanned array (LESA) for use in surveillance and communications applications, where a sequence of pulses are transmitted and their returns are collected by the array for further processing. Instead of partitioning the entire wideband frequency into various subbands and then processing them separately using narrowband schemes, a frequency focusing method is proposed here to compensate and focus the wideband spatio-temporal data into a single narrow frequency band. This is made possible by operating with a pre-computed frequency focusing matrix that transforms the data from various frequency slots that are spread across the entire wideband region into a common narrowband frequency for the array outputs.

Abstract: Wireless data services such as wireless email are becoming common, and in particular, “always-on” systems, where new email is automatically forwarded by the service provider to the wireless device. The problem is that there is no effective mechanism for implementing “always-on” systems when the user is moving around a network, or from one network to another. The invention addresses this problem by generating a session key at the service provider's system for a given data session, and returning this session key to the mobile device. Each time the mobile device communicates with the service provider, it enters this session key into a field that will simply pass through the communication network to the service provider. This allows the service provider to manage the data session, preparing proper accounting records and directing the deletion of stale data sessions on network resources.

Abstract: A frame averaging circuit adapted for a color blood flow frame in a medical ultrasound imaging system. The frame averaging circuit comprises two sections, i.e., a recursive calculation section and a non-recursive section. The recursive calculation section employs an IIR filter in combination with a look-up table, and is adapted for dealing with the cases where no change occurs to the blood flow velocity direction. The non-recursive section compares the blood flow velocity, the energy and the energy prior to wall filtering of the color blood flow echo signal to various threshold values. Different from the recursive calculation section, the non-recursive section is employed when a change occurs to the blood flow velocity direction.

Abstract: A scan conversion method for ultrasonic imaging is disclosed. The method comprises a storage step for storing sample data derived from ultrasonic echo signals into a memory; a conversion step for performing conversion between target coordinate points in a display coordinate system and interpolation coordinate points in a sampling coordinate system; and an interpolation step for interpolating several sample data adjacent to the interpolation coordinate points to obtain the interpolation data at the interpolation coordinate points, wherein the interpolation step includes a nonlinear interpolation substep selected for low-pass filter of the ultrasonic echo signals. When interpolation is conducted along Axis ? of the polar coordinates, 4-point interpolation may be used. The interpolation coefficient may be based on cubic B-spline function, which has relatively uniform low-pass filter effects, thereby reducing noise result from interpolation in ultrasonic image.

Abstract: A hybrid constant current control system that uses both pulse width modulation (PWM) and pulse frequency modulation (PFM) control. When transitioning from constant voltage mode to constant current mode the present invention can continue to control using PWM. Thereafter, when the voltage has dropped, the present invention smoothly transitions to PFM mode. The point of transition is based upon the switching frequency and the lowest rated voltage of operation. The system and method avoids very short (narrow) Ton times which ensures accurate constant current (CC) control with bipolar junction transistor (BJT) devices. The present invention also avoids acoustic noise because the switching frequency is maintained at a high enough level to avoid such acoustic noise even when the energy transferred through the transformer is still substantial and the output voltage is not too low.
