Abstract: A cooling system is described that includes a housing portion at least partially defining a cooling cavity, the housing portion including a member having multiple fins extending from a surface thereof into the cooling cavity. The cooling system also includes multiple walls, each of the walls supported in the cooling cavity by at least one of the fins. The walls are configurable, and a configuration of the walls establishes one of multiple paths for fluid flow through the cooling cavity.

Abstract: A telepresence robot may include a drive system, a control system, an imaging system, and a mapping module. The mapping module may access a plan view map of an area and tags associated with the area. In various embodiments, each tag may include tag coordinates and tag information, which may include a tag annotation. A tag identification system may identify tags within a predetermined range of the current position and the control system may execute an action based on an identified tag whose tag information comprises a telepresence robot action modifier. The telepresence robot may rotate an upper portion independent from a lower portion. A remote terminal may allow an operator to control the telepresence robot using any combination of control methods, including by selecting a destination in a live video feed, by selecting a destination on a plan view map, or by using a joystick or other peripheral device.

Abstract: Dual-tone horn assemblies and methods of use are disclosed herein. An example dual scroll assembly includes a nozzle having a first portion of the nozzle has a first diameter and a second portion of the nozzle has a second diameter that has a size that is different from the first diameter, a first spiraled channel that receives air from the first portion of the nozzle. The air traveling through the first spiraled channel produces a first tone at a first frequency. A divider plate is disposed between the first spiraled channel and a second spiraled channel. The second spiraled channel receives the air from the second portion of the nozzle. The air traveling through the second spiraled channel produces a second tone at a second frequency. The first tone and the second tone when produced simultaneously create a dyad.

Abstract: A hoist point anchor includes a base where the base has a contact surface for contacting a flat ceiling and where the base has a plurality of anchor holes emerging at the contact surface for receiving a plurality of respective anchor bolts for anchoring the base to the flat ceiling. A wire rope forms a wire rope loop for attaching a hook where the wire rope loop is attached to the base. The base passes through the wire rope loop.

Abstract: An evaporative cooler is disclosed wherein at the four corners of the usual cube shaped cooler structure is added four outwardly protruding projections, each of the projections having louver openings on both its sides, as well as on the four sides of the cooler, with watered pads immediately behind in order to substantially increase the wetted pad area through which air flows into the evaporative cooler. In addition to the usual interiorly contained blower and water pump mechanisms in the cooler, a pad holding structure is disclosed to accommodate a single pad for each of the angled side members of the evaporative cooler, the structure including in addition to the side member a plurality of connected wire screens which attach to the side member at its edges, the wire screens and the side member compressibly encompassing a single pad over the whole side.
