    摘要: A current steering-type gain control circuit provides a non-zero minimum gain in response to readily reproducible control signal conditions and without requiring sophisticated control-signal-generating circuitry. The gain control circuit is adapted from a conventional differential pair of current-steering transistors, biased by first and second control signals respectively. To provide a well-defined non-zero minimum gain, the gain control circuit includes at least one additional current steering transistor that further steers current to the output when conducting in the minimum gain state. By further including one or more additional pairs of current steering transistors, the gain control circuit also provides a plurality of well-defined states with gains between the maximum and minimum gain values of the circuit. The minimum and intermediate gain values, may be selected by varying the physical characteristics of the current steering transistors which may be BJTs or FETs. The circuit may be implemented in a single-ended or differential configuration.

    摘要: A method of detecting and measuring separately the components of vector dynamics on the surface of a vibrating object comprises directing three beams of coherent light onto a common spot on the surface. Each of these beams has a known optical frequency. Two are arranged symmetrically about a normal to the surface at the point of incidence and the third is arranged asymmetrically about the normal with respect to both the first and second beams. Superposition of each beam with the others on the surface produces scattered light embodying characteristic beat or carrier signals equal to the difference in frequencies between the beams. Vector dynamics including velocity and displacement of the vibrating surface induces Doppler shifts in the beams, which, in turn results in a modulation of the carrier frequencies resulting from the superposition of the beams. Each carrier frequency is then isolated and demodulated to produce a signal corresponding to various components of the vector dynamics on the surface that cause the modulation. Further analysis extracts information about the frequency and magnitude of resolved vector dynamics on the surface. The method can be applied at several locations on the object's surface to determine vector dynamics at several points simultaneously.

    摘要: A system and a method for determining aiming point and/or six degrees of freedom of an aiming device. The system include the aiming device, a camera mounted thereon, and a computing device. The aiming point is an intersection between a line of interest (LOI) of the aiming device and surface of an aimed object. A parallel auxiliary line (PAL) is a line starting from the camera and parallel to the LOI. The PAL is a point (PAL-T) in a template image captured by the first camera. The computing device is configured to: provide a reference image; map the template image to the reference image; project the PAL-T to the reference image using the mapping relation to obtain a reference point (PAL-R); determine 3D coordinates PAL-3D of the PAL-R; and determine 3D coordinates of the aiming point based on the PAL-3D and a relationship between the LOI and the PAL.

    摘要: When a user equipment (UE) is operating in connected mode in a Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) network all time slots may be allocated to communications, leaving insufficient time for the UE to perform measurement of neighboring radio access technologies (RATs). The UE may select one out of every N number of transmit time intervals (TTIs) to halt regular communication and reserve that TTI for purposes of inter-RAT measurement.
