Abstract: Embodiments of the invention may present a full-duplex nonreciprocal-beam-steering transmissive phase-gradient meta-surface. The metasurface may comprise a conductor layer interposed between two dielectric layers. Each of the dielectric layers may comprise a plurality of unit-cells embedded therein. Each of the unit-cell may comprise phase shifters and antenna elements. The meta-surface may function such that when an electromagnetic wave is received at the surface of the metasurface, the metasurface may transmit a wave having a similar or identical frequency to the frequency of the received wave but to a different direction in space.

Abstract: An embodiment of the present disclosure provides a method using a computing device to initiate play of media within a medical examination or treatment room. The method may include: capturing a plurality of images by a one or more image capturers; determining whether any persons are within a predefined boundary area in one or more of the images using a face detector or person detector; determining whether any persons are outside of the boundary area in one or more of the images using the person detector; and initiating play of media when a first person is determined to be within the predefined boundary area and no persons are determined to be outside of the boundary area in the images.

Abstract: A computer system generates medical messages based on an analysis of medical information associated with healthcare providers. The analyzed medical information may be derived from medical records and/or insurance claims, such as those that may be managed by a clearing house entity that manages the processing of medical insurance claims. Healthcare providers having certain patients that meet various analysis criteria may be identified for purposes of generating the messages that can serve to inform the health care providers about potential medical treatments and procedures, such as new drugs, that be significant for the health care provider and may also be significant to the patients of the health care provider who may be identified in the messages.
