摘要： A laser ranging system (5) includes a light source (32, 34) emitting a beam (31) of collimated light. A beam splitter (12) polarizes the beam with a first type of linear polarization. A wave plate (14) receives the beam from the beam splitter (12) and polarizes the beam with a circular polarization. A movable mirror (16) scans the beam across a target (22), receives a return beam (17) from the target, and reflects the return beam toward the wave plate (14). The wave plate polarizes the return beam with a second type of linear polarization. The beam splitter (12) receives the return beam (23) from the wave plate (14). A detector (20) detects arrival of the return beam from the beam splitter (12). A circuit (18) determines a distance to the target as a function of a time interval between emission of the beam (31) of collimated light and arrival of the return beam (23).

摘要： The present invention provides a system and method for controlling operation of a resonance MEMS mirror (1901). The system and method includes activating either an in-plane or staggered MEMS mirror via sets of activation pulses applied to the MEMS mirror, detecting (1915) current at the MEMS mirror, generating a window for detecting a change in a direction of the current at the MEMS mirror, and terminating the window and the activation pulse if a change in the current direction is detected during the window. In some embodiments, two sets of activation pulses are applied to the MEMS mirror.

摘要： An interpolation filter (50) for interpolating a digital signal (x (n)) includes a cascade of template filters (40), each having an identical template transfer function A (z), which is arranged to receive and filter an input sequence representing the digital signal sampled at an input sampling rate. Ancillary circuitry is coupled to the cascade so as to produce first (y 0 (n)) and second phase outputs (y 1 (n)). A multiplexer (41) is arranged to multiplex the phase outputs in order to generate an output sequence having an output sampling rate equal to twice the input sampling rate.

摘要： A semiconductor circuit for use in a system for receiving and decrypting broadcast signals such as pay television comprises an input and stores for receiving a decryption key in two portions named mother and daughter portion. The splitting of the key into two portions allows a common main or mother portion to be sent broadcast to a large number of subscribers and for separate daughter portions to be sent to each subscriber or group of subscribers depending upon, for example, entitlements for which the subscribers have paid. The semiconductor circuit is arranged to retrieve the mother portion and a relevant daughter portion to construct a complete decryption key.
