Abstract: In one aspect, a diode includes a substrate having a first type dopant; a buried layer having a second type dopant and formed within the substrate; an epitaxial layer having the second type dopant and formed above the buried layer; and a plurality of regions having the first type dopant within the epitaxial layer. The plurality of regions includes a first region, a second region, and a third region. The diode also includes a base well having the first type dopant and located within the epitaxial layer and in contact with the third and fourth regions. In a reverse-bias mode, the diode is an electrostatic discharge (ESD) clamp and forms parasitic transistors comprising a first bipolar junction transistor (BJT), a second BJT and a third BJT.

Abstract: Disclosed is a portable rehabilitation apparatus and method for use of the apparatus by a user or patient. The apparatus is adapted for transitioning between a collapsed state to facilitate the mobility of the rehabilitation robot (e.g., using wheels) and an open state for operation of the rehabilitation robot by the user. The apparatus includes the rehabilitation robot that is contained within a compartment defined by a housing which is made up of moveable portions. The apparatus also includes a mast assembly adapted to form a gap between the moveable housing portions in order to provide the user with access to the rehabilitation robot. The mast assembly is further adapted to collapse, thereby eliminating the gap and closing off the compartment when the rehabilitation robot is not in use.

Abstract: In one aspect an electronic device includes a substrate having one of a p-type doping or an n-type doping, a first well in the substrate, a second well in the substrate, a third well in the substrate between the first and second wells, a first terminal connected to the first well, a second terminal connected to the second well, an electrostatic discharge (ESD) clamp connected to the first and second terminals and a transient voltage source connected to the third well. A doping type of the first, second and third wells is the other one of the p-type or n-type doping. The ESD clamp is configured to clamp the first and second wells at a clamp voltage during an ESD event and the transient voltage source is configured to provide a voltage during the ESD event that is less than the clamp voltage.
