    摘要： A circuit for operating high-pressure discharge lamps, wherein a voltage transformer for power supply to a loading circuit includes a connection for the high-pressure discharge lamp (La) and for the secondary winding (L1b) of an ignition transformer (T1) for an impulse ignition system for igniting a gaseous discharge in the high-pressure discharge lamp. The loading circuit includes at least one capacitor (C1) serially arranged with the secondary winding (L1b) of the ignition transformer (T1) when the impulse ignition system is reconnected, the capacity of the capacitor (C1) being selected in such away that the capacitor (C1) substantially forms a bridging for ignition impulses generated by the impulse ignition device in such a way that after ignition of the gaseous discharge in the high-pressure discharge lamp (La), at least one partial compensation of the ignition transformer (T1) is produced when the lamp current passes through the secondary winding (L1b).

    摘要： Techniques are disclosed for measuring an amount of flicker produced by a light source. In one embodiment, a flicker measuring device includes a photo sensor to measure the amount of light produced by the light source, a dedicated processor to receive and process data from the photo sensor, a memory bus coupled to an analog-to-digital converter (ADC) and to a first memory, and a direct memory access (DMA) bus coupled to the ADC and to a second memory. In another embodiment, a flicker measuring system uses a light sensor, an associated circuit and a portable computing device (PCD), such as a smart phone, to measure an amount of flicker produced by a light source by sending an electrical signal from the light source and associated circuit via an audio output to an audio sub-system of the PCD, so that the PCD may calculate the flicker value.

    摘要： Various embodiments disclosed herein include a method for determining the position of a computing device. The method may include obtaining, by the computing device, an image of a subset of luminaries from a plurality of luminaires located in an indoor environment, in which each subset grouping of luminaires in the plurality of luminaires is uniquely identifiable. The computing device may then compare the subset of luminaires to a database storing each uniquely identifiable subset grouping of luminaires in the plurality of luminaires, in which the database includes position information for each luminaire in the plurality of luminaires, and determine the position of the computing device based on the comparison of the subset of luminaries to the database.

    摘要： Techniques are disclosed for augmenting light-based communication (LCom) receiver positioning using, for example, an inertial navigation system (INS). An LCom receiver INS may utilize one or more on-board accelerometers and gyroscopic sensors to calculate, via dead reckoning, the position, orientation, and velocity of the receiver. In this manner, the receiver can calculate its relative position using the INS based on a reference point or location. In some cases, the receiver may also or alternatively determine its location or position using a global positioning system (GPS), Wi-Fi-based positioning system (WPS), or some other suitable positioning system. When no LCom signals are in the FOV of the receiver and/or the link is lost to other positioning systems, the receiver INS may be used to augment the receiver positioning. In some cases, the INS mode may run parallel to other positioning techniques to continuously calculate the relative position of the receiver.
