Abstract: A differential current mode amplifier circuit (5,5′) includes a first circuit leg having a first current source providing a current I1 coupled in series with a first transistor (m1) at a first circuit node (n1). The first transistor has a control terminal for coupling to an input signal potential (Vs). Vs is obtained from a unit cell of a radiation detector array, and is indicative of a magnitude of an integrated, photon-induced charge. The first circuit leg outputs a first output current (Is). A second circuit leg includes a second current source providing a current I2 coupled in series with a second transistor (m2) at a second circuit node (n2). The second transistor has a control terminal for coupling to an input reference potential (Vr). The second circuit leg outputs a second output current (Ir). A resistance (Rs) is coupled between the first circuit leg and the second circuit leg at the first circuit node and the second node.

Abstract: A method and related system provides an array of sensing elements located in rows and columns, and each column of sensing elements has a connected circuit chain which processes the signals from the sensing elements in that column. Each circuit chain produces a signal with a corrective gain value calculated for it relative to the datum of the array which is selected for the point where signal strength would be strongest. The method and device is capable of being used in a starring or scanning type array mode.

Abstract: A charge transfer structure (30) includes a substrate comprised of semiconductor material and, coupled to a surface of the substrate, a plurality of serially coupled devices each having a gate terminal. The plurality of serially coupled devices include a first single port device (D1) defining a first primary charge storage well, a second single port device (D3) defining a second primary charge storage well, a first two port device (D2) defining a first transfer device, a second two port device (D4) defining a second transfer device, and two instances of a third two port device each defining a cascode device (CD). The ports of these devices are serially coupled together in an order given by D1, D2, CD, D3, D4, CD for transferring charge between the first and second primary charge storage wells. Charge is inserted into and withdrawn from each of the first and second primary charge storage wells through a single diffusion that functions as both an input port and an output port.

Abstract: A lean burn gas turbine combustor has a premixer zone receiving compressor discharge air through openings in a combustor liner. A fuel nozzle has an upstream orifice 52, a downstream orifice 56, and a captured response volume 54 therebetween. Upstream orifice 52 affords a high pressure drop for gaseous fuel to approximately the pressure of the compressor discharge air. The low pressure discharge orifice affords a pressure drop comparable to the pressure drop across the openings of the combustor liner for the air supply. The dynamic pressure response characteristics of the fuel and air inlets to the premixer zone are substantially matched to eliminate variations in fuel/air concentration resulting from pressure variations in the premixer zone.

Abstract: A system for introducing N cables into an anechoic chamber, where N.gtoreq.1 comprising a channel having an electrically conductive interior, and an electrically conductive entrance in communication with the chamber such that the cables can extend from the channel into the chamber. The system is also comprised of a housing made of a conductive material disposed such that it forms an electrically conductive seal with the channel entrance. There is also a lossy material disposed inside and essentially filling the housing through which the cables extend. In a preferred embodiment, electricaly magnetic radiation having a frequency of up to 100 GHZ is essentially prevented from escaping the chamber. The present invention also pertains to an interface through which N cables, where N.gtoreq.
