An ultrasonic sensing apparatus held next to a target can detect vital signs of the target. The ultrasonic sensing apparatus includes a first flexible circuit board, a transmitting layer, a readout layer, and a receiving layer. Emitting elements in the transmitting layer generate ultrasonic signals and the receiving layer receives reflected ultrasonic signals and converts the reflections into electrical signals. The emitting elements are staggered in relation to elements of the receiving layer for better resolution and accuracy. The readout layer reads the electric signals for calculating vital signs. The readout layer includes input lines and output lines and readout pixels are defined by the crossing points of input and output lines. Ultrasonic signals are generated during a first period, and the reflections are read in a second period next following. The readout layer completes one reading operation corresponding to one readout pixel during the second period.

A device and process is disclosed for creating detailed volumetric ocean els, which in turn are used as inputs for naval tactical and oceanographic analysis. Near-real-time volumetric modelling is accomplished by continuously integrating, filtering, interpolating, and extrapolating oceanographic data (e.g., temperature, sound velocity, conductivity, salinity, bathymetry, current, chlorophyll) from historical data bases, forecasts, remote sensors, and onboard sensors. The value of the invention can be appreciated in the detailed, time-varying, three-dimensional ocean models which can be realized for mesoscale and smaller areas and the ability to use these more detailed and timely ocean models for three-dimensional acoustic propagation predictions and combat control algorithms. Tactical and oceanographic models are computed using an advanced processor and the results are displayed using three-dimensional visualization softwaare and hardware techniques. The invention may be used from a submarine, surface ship, or aircraft.

An interface unit writes and reads the multiplexed data at the service clock rate and a read clock rate respectively. An encoding and mapping unit performs encoding and mapping on the multiplexed data using a symbol clock rate to generate symbol data, and sends the symbol data to up conversion units.

A stream control unit adjusts the service clock rate according to a water line error generated by the interface unit, so that the service clock rate is equal to the read clock rate. As a frequency and a phase of the system clock are fixed, even ACM switching occurs, the system clock is stably transferred.

34 Compensation of flight path deviation for spotlight SAR US11433707 2006-05-12 US07277042B1 2007-10-02 Kwang M. Cho; Leo H. Hui
A radar acquires a formed SAR image of radar scatterers in an area around a central reference point (CRP). Target(s) are within the area illuminated by the radar. The area covers terrain having a plurality of elevations. The radar is on a moving platform, where the moving platform is moving along an actual path. The actual path is displaced from an ideal SAR image acquisition path. The radar has a computer that divides the digital returns descriptive of the formed SAR image into multiple blocks, such as a first strip and an adjacent strip. The first strip is conveniently chosen, likely to generally align with a part of the area, at a first elevation. An adjacent strip covers a second part of the area at a second elevation. The first strip is overlapping the adjacent strip over an overlap portion. The first and second elevation are extracted from a terrain elevation database (DTED). Horizontal displacement of returns (range deviation) is computed for each strip using the elevation information from the terrain elevation database. Taylor series coefficients are computed for the horizontal displacement due to terrain elevation using the ideal path, the actual path and central reference point. Actual flight path deviation is available at each pulse position while azimuth frequency is given in azimuth angle off mid angle point. Remapping between indices in two arrays is also computed. Phase error compensation and compensation in azimuth (spacial frequency) is computed using the Taylor series coefficients, a Fast Fourier Transform and an inverse Fast Fourier Transform for each strip. Phase error compensation is applied to the digital returns from each strip to obtain the SAR image. The SAR image is further improved by having the first strip corrected data and the second strip corrected data merged over the overlap portion to generate a relatively seamless SAR image.
