摘要： Apparatus for demodulating an incoming digitally phase modulated analog signal to reproduce symbol data carried by the signal. Specifically, the demodulator relies on first counting, on a free-running and modulo basis, pulses of a fixed-frequency reference clock signal to form a counted value. The incoming signal is converted to a one-bit phase modulated digital signal. At the occurrence of a pre-defined point in the one-bit phase modulated signal, typically a rising edge occurring at the symbol rate, the counted value is stored as phase information. Within each symbol period, a difference between current and immediately prior counted values, i.e. the latter being a current value but delayed by one symbol period, is determined. This difference, i.e. phase change data, is subsequently sampled and decoded to yield reproduced symbol data, as well as, used, through a phase locked loop, to generate a data clock and the symbol clock.

摘要： A movement detection device includes a self-sustaining movement detection unit which is attached to an operator's body and detects a movement or a posture of an attached part of the operator's body. An image pickup section picks up a projected image from an optical system which simultaneously inputs a peripheral image. An image conversion section converts an all azimuth image picked up by the image pickup section into a cylindrical panorama image. An image recognition section includes cylindrical panorama images at different times. A camera posture estimation section acquires movement information of the image pickup section based on a comparison result of the image recognition section. A space sensor posture estimation section acquires a position/posture of the attached part in a space based on information of the self-sustaining movement detection unit and the camera posture estimation section.
