A memory array includes a memory layer that has hysteretic domains with domain axes extending between first and second memory layer surfaces. A conductive layer on the first memory layer surface has anisotropically increased electrical conductivity in a thickness direction. A movable conductive probe has a contact area on the conductive layer and moves to access a selected hysteretic domain.

An UV-C device may include several UV-C light sources (e.g., UV-C LEDs) and such UV-C LEDs may have UV-C reflecting structures arranged to direct UV-C in a particular direction and at a particular size and shape. Doing so may, for example, increase the UV-C in a particular direction or working area. A UV-C generating device may be utilized in an air stream, such as an air duct, to sterilize air from that air stream. Multiple UV-C inactivation devices may be coupled in series and placed into a single housing for in order to increase the efficacy of the UV-C inactivation device. The inlet of the device may draw air using an inlet module attachment (e.g., a hood with one or more than one inlet hood) and may output air using an outlet module attachment (e.g., a duct to deliver air to an outflow air duct). Computational fluid dynamic software may be provided where UV-C inactivation devices may be positioned (e.g., manually or autonomously by an adaptive algorithm) to determine impact on airflow against various pathogens (e.g., and/or SARS-CoV-2).

Doing so may, for example, increase the UV-C in a particular direction or working area. A UV-C generating device may be utilized in an air stream, such as an air duct, to sterilize air from that air stream. Sound suppression compartments may be placed around a UV-C generating device inlet and/or a device outlet to reduce sound from the UV-C generating device. Human perceivable (e.g., audible, tactile, and/or visual) notifications may be utilized to provide notification of different modes of operation and/or different efficacy levels (e.g., percent ranges of inactivation of a particular or multiple particular viruses, bacteria, spores, etc.

An air sanitization device is provided where a UV-C generator applied UV-C to infected air for sterilization and then the sterilized air is used to cool heat sinks attached to the UV-C. One or more fans can be utilized to push and/or pull air through the device. For example, the fans may create airflow in the device above, for example 200 liters per minute or above 400 liters per minute. Accordingly, a closed air system with a fan may push air through a UV-C generation device to sanitize air and the sanitized air may be pushed over a heat sink attached to the UV-C generation device and then pushed out of the closed air system into the environment. Thus, sanitized air may be circulated by the fan while being air cooled in a manner that does not circulate contaminated air.

Doing so may, for example, increase the UV-C in a particular direction or working area. A UV-C generating device may be utilized in an air stream, such as an air duct, to sterilize air from that air stream. Air may be pushed out of an annulus at the end of an air inactivation device and an annulus outlet cone may be provided in the middle of the annulus to assist, for example, inactivated air in moving smoothly away from the device and reduce pressure at the annulus exit. A UV-C inactivation tube may have UV-C reflective structures at each end to permit air to flow through the tube while reflecting UV-C light back into the tube.
