Abstract: Corrosion resistant thermoelectric devices and methods of manufacturing them are disclosed herein. In some embodiments, a corrosion resistant thermoelectric device includes a semiconductor layer; a corrosion resistant top metallization layer formed on a top surface of the semiconductor layer; and a corrosion resistant bottom metallization layer formed on a bottom surface of the semiconductor layer, where the bottom surface of the semiconductor layer is opposite of the top surface of the semiconductor layer. In this way, the corrosion resistance of the device is provided by the intrinsic properties of the materials used rather than provided by the packaging or a surface coating. As such, the corrosion protection can be ensured and verified by control of the materials used to construct the device. This approach is also less susceptible to damage from shipment, handling, integration, attachment, and assembly operations because the corrosion protection is intrinsic to the materials used in construction.

Abstract: Light emitting devices include an LED that includes an n-type semiconductor layer and a p-type semiconductor layer that is stacked on top of the n-type semiconductor layer. A p-contact metallization stack is on top of the p-type semiconductor layer. An opening extends through the p-type semiconductor layer and the p-contact metallization stack that has a first region that penetrates the p-type semiconductor layer to expose the n-type semiconductor layer and a second region that penetrates the p-contact metallization stack. A bond metal stack is on top of the p-contact metallization stack, and a metal spacer layer is provided between the bond metal stack and the stacked semiconductor layers. The metal spacer layer fills the first region and at least partly fills the second region of the opening so that a lower surface of the bond metal stack is above a top surface of the p-type semiconductor layer.

Abstract: A patient monitor includes an enclosure which is secured to the bed of a patient. The enclosure is electrically connected with a nurse's call panel and the enclosure serves to mount a jack which is electrically connected to the nurse's call panel. This jack includes a normally closed switch which is opened when a mating plug is installed in the jack. The plug is connected by a cord to the gown of the patient in the bed. When the patient attempts to leave the bed the patient's motion pulls the plug from the jack, thereby allowing the switch to close and signalling via the call panel the patient's attempt to leave the bed.
