摘要： An apparatus and method for burning-in an electronic ballast for a lamp. The apparatus comprises a first stage for emulating an input impedance characteristic of a lamp for the electronic ballast and a second stage connected to the first stage for providing energy feedback to a power supply. An input of the first stage connects in use to the electronic ballast to be burnt-in. An output of the second stage connects in use to the power supply to provide energy feedback to said power supply from the electronic ballast being burnt-in. The energy-recyclable burn-in apparatus can emulate the lamp characteristics from start up to the steady state, process high-frequency ballast output power and recycle the power back into the power grid. The burn-in method includes operating the apparatus for a predetermined period of time such that a voltage applied to the electronic ballast simulates a steady-state operation of a lamp for the electronic ballast.

摘要： Multi-ported memory systems (e.g., register files) employ self-timing for operational synchronization. Thus, rather than using a reference clock duty cycle for operational synchronization, as in conventional multi-ported register files, embodiments of the present disclosure employ self-timing for such operational synchronization. According to certain embodiments, self-timing is employed to synchronize all the internal events within the memory so that all the events are spaced in time for appropriate synchronization. For instance, the completion of one event leads to triggering another event, the completion of which leads to triggering another event, and so on. Thus, in one embodiment, the self-timing is achieved by referencing the operational events with the memory (or register file) to each other, rather than to a reference clock duty cycle.

摘要： A memory device utilizes selective precharge and charge sharing to reduce a bit line voltage before accessing a bit cell. A reduction in bit line voltage is achieved by precharging different sections of the bit line to different voltages (e.g., a supply voltage and ground) and using charge sharing between these sections. Read stability improves as a result of the reduction of bit line voltage. The relative capacitance difference between bit line sections determines the bit line voltage after charge sharing. Thus, the memory device is tolerant to process or temperature variations. The bit line voltage may be controlled in design by selecting the sections that are precharged to supply voltage or ground.

摘要： A high-efficiency electronic thermal management system and method providing a heat riser having stackable blocks of thermally conductive material that include an upper block and a lower block, wherein the lower block has a lower surface mounted in thermal communication with a heat source. The lower block having an inclined upper surface configured to be in thermal communication with a block directly above, having a complemental inclined surface. These blocks are elastically coupled. The upper block may slide along the lower block allowing for vertical and horizontal axial elastic adjustment while providing consistent pressure to both the heat source and a cooling source to provide for heat dispersion along a thermal pathway from the heating source through the lower block, upper block, and to a cold plate cooling source. The cold plate also has internal fins and flowing liquid for heat dispersion.

摘要： An apparatus that can operate with electronic ballasts (10) for electric discharge lamps to drive dc-powered lighting equipment (26) is provided. The apparatus is directly connected to the output of the electronic ballast (10) and is then used to control the power being supplied to the dc-powered lighting equipment (26). The maximum power delivered to the dc-powered lighting equipment (26) is substantially equal to the rated output power of the electronic ballast (10). A switching converter is acted as the necessary input impedance for the electronic ballast (10). Thus, the active power and reactive power drawn from the electronic ballast (10) can be controlled. The output of the switching converter provides dc power for the dc-powered lighting equipment (26).
