摘要： A passive measuring technique and system processes and analyzes imprecisely reported location estimates collected from a plurality of mobile devices. The number and socio-demographic composition of persons within defined areas of interest are estimated over time. Each mobile device is assigned to a group and identified by an anonymized identifier, and the identifiers of devices within each group are refreshed on a rolling basis to further enhance privacy. A statistical weighting approach is applied so that each device represents a fraction of the population and socio-demographic profile of one or more segmentation districts. Users requesting a defined area of interest via a communication network receive an estimate—derived by modeling respectively anonymized mobile devices within an area of interest over a selectable time period as corresponding, statistically weighted devices—of the number and socio-demographic profile of all persons within the area of interest over the selectable time period.

摘要： A dynamic step dimming interface is provided that allows a ballast to energize a lamp in a dim mode or a normal mode. The ballast includes a lamp controller that energizes the lamp using an oscillating current. The oscillating current is also provided to a voltage monitor, which indicates the voltage level of the oscillating current, and to a rectifier, which provides an output indicative of the oscillating current. The rectifier is responsive to user input indicating whether the dim mode or the normal mode is to be used. A processing circuit receives the voltage level from the voltage monitor and provides a mode command to the ballast, indicating the lamp mode, based on inputs received, and provides a reference voltage to a comparator. The comparator receives the rectifier output and the reference voltage, and generates a voltage indicative of a power level of the lamp for the processing circuit.

摘要： A ballast for energizing a lamp at a lighting level selected from a plurality of lamp lighting levels. The ballast includes a buck converter circuit configured to receive a DC voltage signal having a substantially constant magnitude. The buck converter circuit has a duty cycle for generating a lamp voltage output signal from the DC voltage signal. The lamp voltage output signal has a magnitude that is varied by the duty cycle to energize the lamp at the plurality of lamp lighting levels. A controller is configured to receive a dim input signal indicative of the selected lamp lighting level and to provide a control signal to the buck converter circuit as a function of the dim input signal. The control signal indicates a particular duty cycle corresponding to a lamp voltage output signal having a magnitude for energizing the lamp at the selected lamp lighting level.

The buck converter includes a transistor, a capacitor, a diode, and an inductor. The switching component has a predetermined breakover voltage value and is configured to provide a start up signal to the inverter when voltage at the switching component increases to the predetermined breakover voltage value. A control circuit is configured to monitor the voltage at the switching component while the voltage at the switching component increases to the predetermined breakover voltage, and is configured to generate a gate drive pulse at a gate terminal of the transistor when the voltage at the switching component reaches a predetermined voltage that is less than the breakover voltage of the switching component.

摘要： A ballast used with an input power source for energizing a lamp. The ballast includes a power stage, a controller, an internal power supply for the power stage and the controller, and an input switch. The power stage energizes the lamp with power supplied by the input power source. The internal power supply is connected to the power stage for receiving power from the power stage and is connected to the input power source via the input switch for receiving power from the input power supply when the input switch operates in a closed mode. When the input switch operates in an open mode it electrically disconnects the internal power supply from the input power source. The controller selectively operates the input switch in the open mode and the closed mode as a function of the voltage of the internal power supply while the lamp is energized.
