Abstract: Methods, devices and systems are disclosed for inter-app communications between software applications on a mobile communications device. In one aspect, a computer-readable medium on a mobile computing device comprising an inter-application communication data structure to facilitate transitioning and distributing data between software applications in a shared app group for an operating system of the mobile computing device includes a scheme field of the data structure providing a scheme id associated with a target software app to transition to from a source software app, wherein the scheme id is listed on a scheme list stored with the source software app; and a payload field of the data structure providing data and/or an identification where to access data in a shared file system accessible to the software applications in the shared app group, wherein the payload field is encrypted.

Abstract: A light controlled semiconductor switch (LCSS), method of making, and method of using are provided. In embodiments, a vertical LCSS includes: a semiconductor body including a photoactive layer of gallium nitride (GaN) doped with carbon; a first electrode in contact with a first surface of the semiconductor body, the first electrode defining an area through which light energy from at least one light source can impinge on the first surface; and a second electrode in contact with a second surface of the semiconductor body opposed to the first surface, wherein the vertical LCSS is configured to switch from a non-conductive off-state to a conductive on-state when the light energy impinging on the semiconductor body is sufficient to raise electrons within the photoactive layer into a conduction band of the photoactive layer.

Abstract: A method for servicing a section of a first flow line of a redundant flow line system with a second flow line in a closed-loop liquid cooling system. The method can include draining liquid from the first flow line through a liquid transfer assembly and servicing the section of the first flow line. The method can also include transferring liquid from the second flow line to the first flow line through the liquid transfer assembly and decoupling the liquid transfer assembly from the first flow line and the second flow line. The method can also include coupling the liquid transfer assembly to and between the first flow line and the second flow line.

Abstract: A filter housing can support filter media for a fan arrangement. The filter housing can include a filter body with a first opening at a first end and a second opening at a second end. A bell portion can be disposed between the air inlet opening and the air outlet opening and can define a cavity within the housing body. An air-permeable filter support can extend into the cavity to support the filter media within the cavity, with the filter media spaced apart from at least one of the first and second openings.

Abstract: A float drain for an enclosure can include a basket to collect liquid from the enclosure, a sealing structure surrounding an outlet of the basket, and a float configured to seat against the sealing surface to prevent fluid flow out of the outlet and to rise off of the sealing surface due to buoyancy forces as the liquid collects in the basket. The float drain can include other features, including: ribs or other protrusions extending into an interior are of the basket to space the float apart from an inner wall of the basket; an angled orientation of the sealing surface; and a trough, at least partly defined by the sealing structure, to collect debris.

Abstract: Embodiments of the invention provide an air conditioning (AC) unit including a pre-filter and a water-repellent filter. The water-repellent filter prevents moisture and dirt in the outdoor air from entering the AC unit through depth filtration. The AC unit also includes a vertical partition separating an outside section from an inside section, with a vent allowing air flow between the outside section and the inside section, and an economizer assembly including a damper.
