Abstract: A sensor includes a gain stage with a differential amplifier with an adjustable gain. The differential amplifier may change its gain in response to the magnitude of a signal readout from the pixel array. The differential amplifier includes an input transistor with an adjustable transconductance. A transconductance controller can change the bias currents supplied to one or more sets of parallel transistors in the input transistor and consequently change the transconductance, and power consumption, of the input transistor. The transconductance controller can select a transconductance setting that is associated with a selected gain setting in order to more efficiently match the power consumption of the amplifier to its gain.

Abstract: A strategy for decreasing hydrocarbon emissions from a plastic fuel tank assembly having a multilayer plastic fuel tank (10) and at least one overmolded fuel tank attachment (100). The strategy consists of two basic components. First, the swelling properties of the overmolded outerlayer (116) of the fuel tank attachments 100 are exploited to close possible leakage paths between the barrier resistant core (101) and the overmolded outerlayer (116) of the fuel tank attachment (100). Second, the barrier properties of the barrier resistant core (101) of the fuel tank attachments (100) are exploited to increase the length of the diffusion path of hydrocarbon molecules out of the multilayer plastic fuel tank assembly.

Abstract: A device for injecting current at radio frequency into electric wiring, comprises a guiding structure (10) of an electrically conductive material consisting of a tapered shell (12) wherein a central vertical wall (20) is suspended determining two half-spaces (S, D) within the shell (12). At the tapered end, the shell (12) and the central vertical wall (20) are respectively connected to the braiding and the central wire of a coaxial cable (17) supplying radio frequency electric current. At the end opposite to said tapered end, a wiring (19) is disposed through the structure (10) perpendicular to the vertical central wall (20) and rests on a base (11) of dissipating material. In one of the two half-spaces, the wiring (19) is protected by a shield (23) integral with the shell (12).

Abstract: Electrically conductive polythiophenecarbonyl polymer networks are provided comprising conjugated crosslinks between polythiophenecarbonyl polymer segments of the network. The network can be formed by crosslinking carbonyl functional polythiophenecarbonyl polymers, such as by self-crosslinking condensation reaction or crosslinking condensation reaction with conjugated diylide and/or conjugated polyamine. The carbonyl functional polythiophenecarbonyl polymers can be prepared by polymerization, such as by electropolymerization of carbonyl functional thiophene monomers (the carbonyl functionality generally being protected during polymerization) and, optionally, suitable conjugated copolymerization monomers such as thiophene, pyrrole and/or carbonyl functional pyrrole.
