Abstract: A method for estimating the location of a beacon from an ensemble of measurements associated with said beacon, where, contained in each measurement, are GPS data from which surfaces of location may be extracted, together with the ID's of beacons detectable at the point of measurement, is disclosed. The method comprises extracting the canonical set of surfaces of location implicit in each of the associated measurements, and determining the estimate of the location of the beacon as the point for which a weighted sum of the squares of the distances to each of the surfaces so extracted is minimized. A system for the compilation of a database of beacon locations from measurements containing a time-stamped recording of the composite GPS signal (which recording is referred to as a datagram), together with the ID's and associated signal strengths of beacons detectable at the point of measurement, is also disclosed. The system comprises GPS signal processing means for extracting, from each time-stamped datagram, the canonic set of surfaces of location, and beacon location estimation means for estimating the location of a beacon from an ensemble of surfaces of location associated with said beacon.

Abstract: A system for measuring the pseudo range from a target GPS sensor to a designated navigational satellite, for use in a satellite positioning system (SPS) is comprised of multiple GPS sensors for receiving and recording portions of the signals transmitted by designated navigational satellites, the recordings referred to as datagrams; and means for transmitting the datagrams to a datagram processing facility wherein the pseudo range from the target GPS sensor to the designated navigational satellite is derived. The datagram processing facility for deriving the pseudo range is further comprised of a pseudo range engine for deriving a pseudo range from a datagram originating with said target GPS sensor, the location of which is to be determined, the derivation accomplished with the aid of a perfect reference; a perfect reference engine for generating a perfect reference from one or more satellite-specific datagrams: and a strong signal suppression engine for synthesizing satellite-specific datagrams from I/F signals recorded by reference GPS sensors designated for the express purpose of perfect reference generation. The perfect reference reduces the minimum signal strength required to acquire and accurately track GPS satellites at or near the horizon.

Abstract: A power converter delivers electrical power from an electrical power source to a load according to a plurality of operation modes, where at least one of the operation modes is a peak current switching mode. Under the peak current switching mode, a switch controller controls the switch in the power converter to be kept on until the current through the switch reaches a peak current value corresponding to a given phase of the input voltage signal to the power converter. The peak current values have a reference shape, which may be a trapezoidal. The power converter may have any topology, such as a flyback-type power converter or a boost-type power converter.

Abstract: A method of regulating voltage at an output of a switching power converter, the converter comprising a switch and pulse generation circuitry, the pulse generation circuitry producing one or more drive signals for cycling the switch ON and OFF, wherein if the switch is cycled ON and OFF according to a cycle of a drive signal, power is transferred from a source to a load. The method includes sensing an output voltage feedback signal, comparing the sensed feedback signal to a reference at a determined time during a cycling of the switch, and regulating an output voltage at the load by controlling whether a cycle of one of the drive signals cycles the switch in response to the comparison.

Abstract: Various three, four and five terminal power supply control packages for controlling delivery of power from a source to a load in both single and dual switch transformer coupled power converters are disclosed. By way of example, a three-terminal control package has a first terminal for coupling to a primary winding of a transformer, a second terminal for coupling to a ground reference and a third terminal for coupling to a source of operating power. An internal power switch has an input coupled to the first terminal, an output coupled to the second terminal, and an activation gate. The package includes pulse train control circuitry coupled to the power switch activation gate and responsive to an error signal for driving the power switch, the error signal derived from an internally generated compensation signal corresponding to an expected voltage loss between the source and the load.

Abstract: A power converter control system is provided which combines a pulse train regulation control technique with a pulse train optimization technique, to control the output level of the power converter, while maintaining optimal performance for other power converter parameters. The power converter control system describe herein provides versatility not previously available in power converter control systems by providing features such as quasi-resonant mode control, discontinuous mode control, and/or power factor correction. A pulse optimizer adjusts or customizes, for example, the ON time, duty cycle or frequency of pulse train pulses output by a pulse generator. The adjusted pulses are gated by a pulse rate controller to selectively actuate a power switch, thereby regulating the output power level and optimize the overall performance of the power converter.
