Abstract: A foldable wall bed including a housing frame, a bed frame, and a casing. The housing frame is configured to be secured to a structure and defines a storage space. The bed frame is configured to support a mattress. The bed frame presents a proximal end that is pivotally secured to the housing frame. The bed frame is pivotable about an axis between a storage position and an in-use position. The casing substantially encloses the housing frame and the bed frame to define an outermost circumambient surface of the bed when the bed is arranged in the storage position or the in-use position.

Abstract: The present invention is directed to touch sensors with arrays of thin-film conductive polymer switches (e.g., diodes or transistors) that can be used to selectively apply voltage gradients across a resistive touch region of the touch sensor substrate. Touches on the touch sensor can then be sensed by measuring the voltage at the touch location on the resistive touch region.

Abstract: The present invention provides a two-terminal, transistor-PTC, circuit protection device that has a reduced size and weight and is particularly suitable for use, for example, in portable electronic devices and high density electronic circuits. According to one embodiment of the present invention, a circuit protection device comprises a positive coefficient temperature (PTC) element and a bipolar transistor having base, collector, and emitter terminals. The PTC element is connected between the base and collector terminals of the transistor. The PTC element may be thermally coupled to the transistor and packaged with the transistor as a hybrid device. An electrical load may be connected to the collector terminal of the transistor. According to another embodiment of the present invention, a circuit protection device comprises a PTC element and a Darlington circuit having base, collector and emitter terminals. The PTC element is connected between the base and collector terminals of the Darlington circuit.
