Abstract: A device includes a touch-mode biometric sensor having a first side facing toward a user and a second side opposite to the first side, and a display arranged under the touch-mode biometric sensor and adjacent to the second side and configured to display an image in response to a sensing result, associated with a biometric feature of the user, of the touch-mode biometric sensor.

Abstract: Embodiments described herein relate to plasma processes. A plasma process includes generating a plasma containing negatively charged oxygen ions. A substrate is exposed to the plasma. The substrate is disposed on a pedestal while being exposed to the plasma. While exposing the substrate to the plasma, a negative direct current (DC) bias voltage is applied to the pedestal to repel the negatively charged oxygen ions from the substrate.

Abstract: An asymmetrical shunt switch for use in a socket of a string of lights resides in an otherwise typical lamp of a string of lights. The present switch is a shaped spring held in position between the two conducting terminals by a holder so that both of its lateral sides contact the terminals when the base is removed. When the base is inserted, a depending prong on the bottom corner of the base presses one side of the shaped spring away from its terminal and thereby allows current to flow through the Dumet wires to the filament.

Abstract: A noise generator for generating multi-octave, high-level, millimeter- and submillimeter-wave noise is disclosed. According to one embodiment of the invention, the noise generator includes: a microwave noise source; a microwave power-amplifier chain; a level-set attenuator; a frequency multiplier; and a transmission structure. The output of the generator has a high-intensity noise power spectrum over a frequency range from about 60 GHz to about 1 THz. This type of noise is particularly suited and has sufficient power for testing and calibrating millimeter- and submillimeter-wave components, devices, and circuits; material evaluation and characterization; and for use as a broadband millimeter- and submillimeter-wave noise source for a Fourier Transform Spectrometer.
