An interface angle estimation system comprising thermal and surface imagers and apparatus for determining an interface angle. The imagers provide imaging data to the interface angle determining apparatus, which determines the interface angle.

A signal of interest is periodically sampled and the samples decomposed into quadrature components. The signal's phase angle at each sample is computed from the ratio of the real to imaginary parts. A linear regression analysis is then performed on the sampled phase data to obtain a best estimate of the signal's phase rate of change. From this estimate, the signal frequency is determined. In superheterodye instruments, the frequency of an input signal can be deduced by analyzing an intermediate ...

In a picture restoring method, an original picture is divided into picture elements arranged in matrix form, the picture elements are grouped into picture element regions each of which has an arrangement of nxn picture elements, and each picture element region is divided into a minute picture element region having an arrangement of 1.5n.times.1.5n minute picture elements. The density levels of the minute picture element in each minute picture element region are determined black or white accordin...

A method and apparatus are described for accurately estimating the concentration of residual fumigant in a commodity in a fumigation chamber from the rate of decline in concentration of fumigant in the exhaust air stream during the aeration period following fumigation. Because the method is nondestructive and lends itself to automation, it us useful for commercial application.

In a motion vector estimation method, a block-based motion vector estimation process (BME) that involves comparing a plurality of candidate vectors is carried out to determine block-based motion vectors, at least a most frequently occurring block-based motion vector (MFMV) is determined, a global motion vector estimation process (GME) using at least the most frequently occurring block-based motion vector (MFMV) is carried out to obtain a global motion vector (GMV), and the global motion vector (...

A mobile transceiver and a method of detecting movement of the mobile transceiver in a radio system. The radio system includes at least one base station and terminals. The movement of the mobile transceiver is measured by at least one acceleration sensor (114 116) to take the movement of the mobile transceiver onto account in the operation of the radio system.

The wire length of an LSI is estimated from a netlist describing connection information of the LSI and a cell library storing information as to cells used in the LSI design, with performing no rough placement and rough wiring by a layout system. Information necessary for wire length estimation is extracted from the netlist and the cell library. A net basic wire length is determined for each fan-out. In a net wire length estimating step, a net wire length for each fan-out is estimated by making r...

A bandwidth estimation in a resource of a data communication system. After a data unit in a data flow has been received, a recent pulse density for the data flow over a period that includes the received data unit and starts from a time point that precedes the received data unit in the flow is computed. An overall pulse density is computed based on the computed recent pulse density and a previous overall pulse density computed earlier for the data flow. The computation of the overall pulse densit...

A method of estimating a digitized data signal transmitted as a sequence of data symbols. The received signal is generally distorted by transmission through a dispersive communications channel. The received symbols can exist in a plurality of different states depending on the number of symbols in the data alphabet and the extent of intersymbol interference. In the present method a near-instaneous soft decision is made (without the need for memory storage) for each estimated symbol using the foll...
