Abstract: This invention relates to a catalyst comprising an inert material impregnated or coated with a mixture or alloy of platinum and rhodium in which rhodium is present in an amount up to 20 wt.%. The catalyst is particularly suitable for use in 1) catalytically reducing an oxide of nitrogen in a gaseous stream, 2) the oxidation of an organic compound in a gas also containing oxygen and 3) the preparation of methane by the steam reforming of naphtha or naphtha distillates.

Abstract: An apparatus, system, and method for voltage regulator (VR) control are provided. An apparatus can include first, second, and third comparators configured to determine whether a load voltage (VLOAD) drops below a lower non-linear control (NLC) threshold, drops below a lower linear control (LC) threshold, and exceeds an upper LC threshold, respectively. The apparatus can include power gates (PGs) configured to adjust an output voltage (VOUT) based on a provided power gate (PG) code. The apparatus can include voltage regulator (VR) controller circuitry comprising synchronous LC circuitry and asynchronous NLC circuitry, the LC circuitry configured to increment or decrement the PG code responsive to the VLOAD dropping below the LC threshold and exceeding the upper LC threshold, respectively, and the NLC circuitry configured to increase the PG code based on a number of consecutive NLC droop events and responsive to the VLOAD dropping below the lower NLC threshold.

Abstract: Disclosed are various embodiments of a mobile advertising display apparatus. In one example, among others, the apparatus can include a display enclosure that includes a first side, a second side, a front side, and a back side. The first side can have a slot, and the back side can have an aperture that enables for a manipulation of content to be moved through the slot. The apparatus can include a flexible connector that has a first end and a second end. The first end can be attached to the back side of the display enclosure and a clamp can be attached to the second end of the flexible connector.

Abstract: A wearable microphone array apparatus and system used as a directional audio system and as an assisted listening device. The present invention advances hearing aids and assisted listening devices to allow construction of a highly directional audio array that is wearable, natural sounding, and convenient to direct, as well as to provide directional cues to users who have partial or total loss of hearing in one or both ears. The advantages of the invention include simultaneously providing high gain, high directivity, high side lobe attenuation, and consistent beam width; providing significant beam forming at lower frequencies where substantial noises are present, particularly in noisy, reverberant environments; and allowing construction of a cost effective body-worn or body-carried directional audio device.
