摘要： A calibration target comprises a target pattern plane having a planar surface and a plurality of markers disposed on the planar surface. An optical axis of the imaging system is at a first angle with respect to the planar surface of the target pattern plane when the calibration target is being used to calibrate the imaging system. The plurality of markers is pre-warped in size and aspect ratio using a set of trigonometric functions that use the first angle and a distance from the imaging system to the marker, so that each of the plurality of markers appears a substantially same size as all others of the plurality of markers when viewed by the imaging system at the first angle. The plurality of markers includes a plurality of localizer features that have known relative positions on the target pattern plane and are used to determine an orientation for each marker.

摘要： This invention concerns remote sensor networks, and particularly energy management for wireless sensor networks. In a first aspect the invention is a wireless sensor node specified to operate for a given lifetime, including an onboard computer system and a set of one or more associated sensors. The computer system operates to periodically sample data from each sensor of the set of associated sensors, and to store a multi-state model representing one or more phenomena described by the collected data. And, the computer system operates to calculate a value associated with movement of the phenomena between the states of the multi-state model, and to adjust the rate of sampling of one or more of the set of associated sensors depending on the calculated value. In other aspects the invention is a network of sensor nodes and a method of operation.

摘要： A system for measuring a capacitor (CSENj) precharges a CDAC (23) in a SAR converter (17) to a reference voltage (VAZ) and also precharges a first terminal (3-j) of the capacitor to another reference voltage (GND). During a measurement phase, the CDAC is coupled between an output and an input of an amplifier (31) and the capacitor also is coupled to the input of the amplifier, so as to redistribute charge between the capacitor and the CDAC. The amplifier generates an output voltage (VAMP) representing the capacitance being measured. The output voltage is stored in the CDAC. The SAR converter converts the output voltage to a digital value representing the capacitance being measured.

摘要： A sensor assembly for sensing a movable object which, in one embodiment, includes a housing defining an interior cavity. A rotor is retained in the cavity. The rotor defines a central bore and a magnet is mounted in an off-center pocket defined by the rotor. The rotor is coupled to the shaft of the movable object whose position is to be measured. A sensor is also retained in the cavity in a relationship at least partially overlying the magnet and adapted to sense at least the direction of the magnetic field generated by the magnet to generate an electrical signal indicative of the position of the movable object. In another embodiment, the rotor and sensor are mounted in separate interior housing cavities separated by an interior housing wall.
