Abstract: Pyrrolidine main protease inhibitors are described that are effective as antiviral compounds.

Abstract: A display may have a pixel array such as a liquid crystal pixel array. The pixel array may be illuminated with backlight illumination from a direct-lit backlight unit. The backlight unit may include an array of light-emitting diodes (LEDs) on a printed circuit board. The display may have a notch to accommodate an input-output component. Reflective layers may be included in the notch. The backlight may include a color conversion layer with a property that varies as a function of position. The light-emitting diodes may be covered by a slab of encapsulant with recesses in an upper surface.

Abstract: Systems and methods are provided for controlling electric and electronic devices. The devices may communicate with each other in a many-to-many, peer-to-peer network to provide control functionality without the need for a central controller. Device-to-device control messages may be implemented over short range, wireless broadcast messages.

Abstract: An apparatus that measures electrical impedance. The apparatus includes a signal generator controlled by a master microcontroller, a plurality of data acquisition channels, each channel containing a microcontroller, a host computer that processes and stores measured values, and a communication line between the host computer and the master microcontroller.

Abstract: The present invention relates to a semiconductor device for production of a gas from a material comprising the gas using light as the sole power source. In an embodiment, the semiconductor comprises a substrate; a solid-state semiconductor layer disposed on the substrate; a photoactive semiconductor top layer further comprising a photoelectrochemical electrode junction; and an interface layer disposed between the solid-state semiconductor layer and the photoactive semiconductor top layer. A surface of the photoactive semiconductor top layer is exposed to both a source of light such as the sun and to the material, e.g. a liquid electrolyte. The gas is liberated from the material, e.g. hydrogen liberated from a liquid electrolyte. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure.
