  • Publication number: 20180177010
    Abstract: An LED driver uses a switch mode power supply either to provide a regulated LED current (in a first mode) that connects directly to the LED arrangement or a regulated LED voltage (in a second mode) to an LED output terminal. An auxiliary power supply is either based on an auxiliary secondary side (i.e. an auxiliary secondary side winding) when in the first mode, or it is based on the regulated LED voltage when in the second mode. The LED driver further comprises an input adapted to receive a standby command for the driver, wherein the main controlling unit is adapted to control the driver in the second mode when receiving the standby command for the driver. In this way, the driver has a single shared stage which can operated in a regulated current (i.e. constant current) mode to drive the LED arrangement directly or a regulated voltage (i.e. constant voltage) mode. It can adaptively change between modes to improve the standby power efficiency. When the load is turned on (e.g.

  • Publication number: 20180164210
    Abstract: A compact device useful for measuring an absorption spectrum of a liquid, such as water with organic contaminants, is provided. The device comprises an array of light emitting diodes (LEDs) each emitting light with a unique spectral peak. A reflector shaped as a half ellipsoid reflects the emitted light to form a reference beam. The reflector has an opening to allow part of the emitted light to form a measurement beam after passing through the liquid. Two photodetectors measure the reference beam and the measurement beam to give a reference intensity and a measured intensity, respectively. The LEDs sequentially emit showers of light one-by-one, giving plural pairs of reference and measured intensities for estimating the absorption spectrum. The device receives energy from a separate power-providing device through wireless power transfer. The power-providing device harvests motional energy of the flowing liquid to generate electrical energy.

  • Publication number: 20180122906
    Abstract: The contact area between a source strap structure of a buried source layer and semiconductor channels within memory structures can be increased by laterally expanding a source-level volume in which the memory stack structures are formed. In one embodiment, sacrificial semiconductor pedestals can be formed in source-level memory openings prior to formation of a vertically alternating stack of insulating layers and sacrificial material layers. Memory openings can include bulging portions formed by removal of the sacrificial semiconductor pedestals. Memory stack structures can be formed with a greater sidewall surface area in the bulging portions to provide a greater contact area with the source strap structure. Alternatively, bottom portions of memory openings can be expanded selective to upper portions during, or after, formation of the memory openings to provide bulging portions and to increase the contact area with the source strap structure.
