Abstract:
A photosensitive pixel with gain stage is disclosed. The photosensitive pixel with gain stage may receive an input light stimulus and output a corresponding output voltage in response to the input light stimulus. The output voltage may correspond linearly to the magnitude of the input light stimulus over a linear operating region and logarithmically to the magnitude of the input light stimulus over a logarithmic operating region. In this manner, the photosensitive pixel with gain stage may be both sensitive to input light stimuli over the linear operating region and may exhibit dynamic range enabling non-saturated response to input light stimuli over the logarithmic operating region.
Abstract:
A shutter assembly includes a first shutter blade having a first toothed arm extending therefrom and a first light transmitting aperture therein, and a second shutter blade positioned adjacent and parallel to the first shutter blade. The second shutter blade has a second toothed arm extending therefrom and a second light transmitting aperture therein. The first and second shutter blades are supported to allow parallel linear motion. A motor gear is disposed between, and meshed with, the first and second toothed arms such that rotation of the gear causes the first and second shutter blades to move linearly in opposite directions between an open position in which the first and second light transmitting apertures are in an overlapping relationship with respect to one another, and a closed position in which the first and second light transmitting apertures are in a non-overlapping relationship with respect to one another.
Abstract:
The present invention relates to a readout circuit for a touch sensor which can increase touch sensing sensitivity regardless of a process variation and a driving voltage of the touch sensor.The readout circuit includes a comparative circuit for setting an input range of a readout signal from the readout line as well as scaling the readout signal to be a required driving range and forwarding the readout signal scaled thus as a touch sensing signal, and an analog to digital converter for converting the touch sensing signal from the comparative circuit as a digital sensing signal and forwarding the digital sensing signal.
Abstract:
An image intensifier tube includes a microchannel plate (MCP) having conductive input and output surfaces disposed in a housing. A conductive lower support is in electrical contact with the output surface of the MCP, and a conductive upper support is disposed above the input surface of the MCP. A shape memory alloy (SMA) lockdown is disposed between the input surface of the MCP and the upper support. The SMA lockdown is configured to provide a lockdown for the MCP in the housing. An SMA upper surface is configured to provide an axial force against the upper support, and an SMA lower surface is in contact with the input surface of the MCP.
Abstract:
In an MCP assembly 10 having one or a plurality of MCPs 5, 6 sandwiched with an input-side electrode 4 and an output-side electrode 7, there provided at the surface facing the MCP 5, 6 of at least either (preferably, both) of the input-side electrode 4 and the output-side electrode 7, is a substantially annular contact face that contacts the MCP surface to fix the same, and there provided at a periphery of the contact face is a separation surface retracted in a direction to be separated from the MCP surface. Thereby, provided is an MCP assembly having a construction enabled to prevent damage to the MCP in manufacturing and handling.

The invention relates to a discharge lamp having a thin film indium oxide coating on the interior lamp envelope surface that effectively reflects UV, near IR and microwave radiation while transmitting light in the visible spectrum, the lamp being a high temperature operating lamp.
Abstract:
A microchannel plate (MCP) for an image intensifier includes an active portion having an input surface area for receiving electrons and an output surface area for outputting multiplied electrons. The input and output surface areas are oriented horizontally with respect to each other and spaced by a vertical distance. A non-active portion surrounds the active portion of the MCP. The non-active portion includes at least one slot extending vertically into the non-active portion and extending horizontally to form a horizontal slotted area. When the MCP is positioned vertically above an electron sensing device having wires looping vertically above the electron sensing device, the slot is configured to receive a portion of the wires, resulting in a vertical clearance between the MCP and the electron sensing device. The wires loop a vertical looping distance above a surface of the electron sensing device, and a portion of the vertical looping distance is configured to be received within the slot of the MCP. The horizontal slotted area may be a rectangle, and the input and output surface areas may also be rectangles.
