    摘要： An uncooled infrared imager and associated microelectromechanical infrared detectors based on an active pixel heat balancing technique are disclosed. The imager is fabricated using a commercial CMOS process plus a simple electrochemical etch stop releasing step. The basic active pixel detector structure consists of a simple cascode CMOS amplifier in which the PMOS devices are built inside a thermally-isolated floating n-well. The intrinsic coupling of the cascode currents with the self-heating of the well forms an electrothermal feedback loop that tends to maintain the well temperature constant. By employing the heat balance between incoming infrared radiation and the PMOS device power dissipation, the responsivity of the detector is controlled by the cascode biasing current.

    摘要： A biosensor can include a fluid flow channel (12), a pulsing mechanism (14), and a binding response measurement mechanism (16). The fluid flow channel (12) can include an inlet (18) to accept a fluid into the fluid flow channel and an outlet (20). At least one binding sensor surface (22) can be oriented within the fluid flow channel. The binding sensor surface (22) can include a fixed binding moiety on the binding sensor surface selected to bind with a complimentary target agent within the fluid to form a complimentary bound duplex. The pulsing and flow switching mechanism (14) can be configured to drive the fluid into the fluid flow channel (12) in a pulsed analyte flow.

    摘要： Embodiments are directed to a ground reaction sensor cluster (GRSC) and to methods for precisely determining zero velocity points and bearing changes using a GRSC and for navigating using a GRSC and an inertial motion unit (IMU) in a global positioning satellite (GPS)-denied environment. The GRSC device itself includes an array of capacitive pressure and shear sensors. The array includes multiple flexible capacitive sensor cells that detect changes in capacitance in response to a footstep. Each cell of the array includes multiple overlapping, fingered capacitors that detect pressure and shear force by determining the change in capacitance in each fingered capacitor. The GRSC device also includes a multiplexing receiver that receives the capacitance inputs from each of the capacitive sensor cells. The multiplexing receiver and other electronic elements further process the received capacitance inputs to determine, based on the pressure and shear forces, the direction and bearing of the footstep.
