摘要： A method and apparatus for improved digital processing of the analog echo signals in a coherent imaging system is described which simplifies the channel circuitry requirements. The analog echo signals detected with a phased array of transducer elements are first compressed in a non-linear manner then expanded non-linearly with analog-to-digital converter means to provide increased instantaneous dynamic range in the overall system. Representative phased array coherent imaging systems having the improved digital processing means are also disclosed.

摘要： An ultrasonic imaging processing system includes transducers and means to generate in an analog fashion, in-phase and quadrature phase signals. These signals are converted to digital form and a butterfly phase rotator circuit is employed to correct for phase differences in beam steering and focusing. In particular, speed and simplicity is achieved through the utilization of read only memory means providing appropriate function values for phase correction in conjunction with digital multiplication and summing circuitry.

摘要： An ultrasonic imaging system for displaying color flow images includes a receiver which demodulates ultrasonic echo signals received by a transducer array and dynamically focuses the baseband echo signals. A color flow processor includes a frequency domain adaptive wall filter which automatically adjusts to changes in Doppler-shifted frequency and bandwidth of the wall signal components in the focused baseband echo signals after the echo signals have undergone Fourier transformation into the frequency domain. The mean Doppler-shifted frequency of the resulting filtered baseband echo signals is used to indicate velocity of moving scatterers and to control color in the displayed image.

摘要： A mobile tracking unit capable of operating in a power-starved environment for a vehicle tracking system includes a navigation set for generating data corresponding to a respective vehicle position. The navigation set is periodically energized at a selected activation rate F.sub.G while the vehicle is moving to generate the vehicle position data. The tracking unit includes an electromagnetic emitter which is capable of transmitting the vehicle position data and which is periodically energized at a selected activation rate F.sub.EM while the vehicle is moving to transmit at least the vehicle position data. A motion sensor is employed for generating data indicative of vehicle motion. A tracking unit controller receives the vehicle motion data and controls the navigation set and the emitter based upon the vehicle motion data so that when the vehicle is stationary each of activation rates F.sub.G and F.sub.EM can be respectively decreased by a predetermined factor, thus reducing the overall power consumption of the tracking unit. The tracking unit controller is further designed to return to activation rates F.sub.G and F.sub.EM upon the motion sensor sensing renewed vehicle motion, thus avoiding loss of vehicle position data during times of renewed vehicle motion.

摘要： A shock detector for measuring intermittent shock events comprises a mechanical delay line to supply delayed output motion in response to input motion along an input axis. A transducer converts the delayed output motion to an electrical signal representative of the delayed output motion. The transducer is generally in a respective inactive state to reduce the power consumption of the shock detector. A relatively low power motion sensor, such as low power accelerometer or tilt actuated switch, is employed for switching the transducer to a respective active state in response to the input motion thereby allowing the shock detector to measure any intermittent shock event regardless of the generally inactive state of the transducer.
