Abstract: A brake assembly includes a base member configured for attachment to the leg of a bed, a brake mounted to the base member, and a visual indicator assembly mounted in relation to the base member. The brake is operable to be selectively applied to prevent movement of the bed and the visual indicator assembly provides a visual indicia of when the brake is one of applied and released.

Abstract: A portable patient lift has spreadable support legs with a feature that enables the legs of the lift to operate in a first range of motion during operation, and a second range of motion for compact folding.

Abstract: A high/low bed comprising a main frame and a pivot plate for supporting for pivotal movement an actuator rod for raising and lowering the main frame relative to a supporting surface. The pivot plate is supported for rotation relative to the main frame via a first pivot point. The pivot plate is further supported for rotation in a plane substantially parallel to the main frame.

Abstract: A portable patient lift comprises a base and a mast that is foldable relative to the base to expose a lower end of the mast. The lower end of the mast protrudes rearward to define one point of a three-point stance when the mast is folded and the lift is set on end.

Abstract: A portable patient lift has spreadable support legs with a feature that enables the legs of the lift to operate in a first range of motion during operation, and a second range of motion for compact folding.

Abstract: A patient lift comprises a base and a foot push pad integrated with the base. The foot push pad provides a high-friction surface to reduce risk that an operator's foot will slip off the base.

Abstract: Active millimeter-wave imaging systems can include an antenna apparatus configured to transmit toward and receive from a subject in a subject position, electromagnetic radiation. A controller can include a transceiver configured to operate the antenna apparatus and produce an output representative of the received radiation, and a processor adapted to convert the transceiver output into image data representative of an image of the subject. The antenna apparatus may move in a partial or continuous loop around the subject, toward or away from the subject, or in an opposite direction to an associated antenna apparatus. Antenna units in the antenna apparatus may be oriented at different angular positions along an array. Antenna arrays may also be formed of a plurality of array segments, and a group of arrays may be combined to form an antenna apparatus.
