Abstract: A system comprising a first expired drug usability device is provided. The first expired drug usability device comprises a first spectrometer and one or more first processors. The first processors are configured to: obtain at least one expired drug machine learning-artificial intelligence (ML-AI) model associated with a pharmaceutical drug; obtain drug expiration information of a sample of the pharmaceutical drug, wherein the drug expiration information comprises spectrometer data associated with using the first spectrometer on the sample; input the drug expiration information into the at least one expired drug ML-AI model to determine usability information associated with the sample of the pharmaceutical drug; and perform one or more actions based on the usability information.

Abstract: In some examples, a thermal control device includes a vapor chamber comprising a fluid to transport heat from a first portion of the vapor chamber to a second portion of the vapor chamber, and an isolation chamber adjacent the vapor chamber and fluidically isolated from the vapor chamber, the isolation chamber evacuated to a pressure less than atmospheric pressure to thermally isolate at least a portion of the vapor chamber.

Abstract: In an example, a light blocker may comprise a bellow to extend from an outer edge of a key to an inner edge of a key window to span a key gap in between the key and the key window. The bellow may extend along a periphery of the key, and the bellow may block light originating from under the key from passing through the key gap.

Abstract: An apparatus is set forth wherein an elliptical seat defined by a major and minor axis includes a plurality of diametrically opposed support legs aligned and coextensive with the minor axis of the elliptical seat, with the seat including a matrix of drainage apertures therethrough, as well as a comfort ridge aligned with the major axis of the elliptical seat. Modifications include telescoping members received within the seat support legs, as well as telescoping links for securing a foot rest member thereon. The foot rest member is also structured for sliding adjustment along the links for adjustment thereof relative to the links. Further, foot support members may include cushioned cavities defined within support members mounted to the seat by flexible lines.
