    摘要: This is generally directed to systems and methods for reading optical black pixel cells. For example, in some embodiments, the columns of a pixel array can be shunted together during an optical black pixel readout phase of the imaging system. This may, for example, help improve correction of column fixed pattern noise or other noise. In some embodiments, the column may be shunted together during the optical black pixel readout phase of the imaging system and not shunted during other phases of the imaging system (e.g., when reading values from active pixel cells, barrier pixel cells, etc). In some embodiments, circuitry for providing the column shunting can be implemented as an independent block of the imaging system. In other embodiments, this circuitry can be implemented within other blocks of the imaging system. As an illustration, the shunting circuitry can be implemented within a VLN block of the imaging system.

    摘要: A keypad assembly is described herein in which the keypad assembly includes a substrate and a plurality of domes positioned on the substrate and configured to translate operator action into a corresponding input for a machine. The keypad assembly also includes a dome overlay positioned over the domes and the substrate in which the dome overlay can create a sealed environment for the substrate and the domes. A light guide that directs light in the keypad assembly and an interlocking component coupled to the light guide can also be part of the keypad assembly. In one arrangement, the interlocking component can selectively compress the dome overlay to assist in the creation of the sealed environment. In another arrangement, the interlocking component can compress the dome overlay by bending the dome overlay at an edge of the substrate.

    摘要: In a method of making a generating device, a plurality of spaced apart elongated seed members are deposited onto a surface of a flexible non-conductive substrate. An elongated conductive layer is applied to a top surface and a first side of each seed member, thereby leaving an exposed second side opposite the first side. A plurality of elongated piezoelectric nanostructures is grown laterally from the second side of each seed layer. A second conductive material is deposited onto the substrate adjacent each elongated first conductive layer so as to be coupled the distal end of each of the plurality of elongated piezoelectric nanostructures. The second conductive material is selected so as to form a Schottky barrier between the second conductive material and the distal end of each of the plurality of elongated piezoelectric nanostructures and so as to form an electrical contact with the first conductive layer.

    摘要: A method and apparatus are provided for operation of an image sensor during signal readout. During a reset operation the gate of a reset transistor coupled to the storage node receives a voltage greater than a threshold voltage to produce a reset of the storage node. During a period where photogenerated charges stored at the storage node are read out the gate of the reset transistor receives a voltage VRST—LOW greater than ground, but less than a maximum voltage which can be stored at the storage node.
