  • Patent number: 8628972
    Abstract: A device for identifying infection by the malaria parasite includes a microfluidic device having an inlet and an outlet and a diagnostic channel interposed between the inlet and the outlet. The diagnostic channel includes a contact surface and a sample pump configured to pump a RBC-containing sample into the inlet. The contact surface may be at least one of hydrophilic and roughened. Malaria infected RBCs (miRBCs) interact with the contact surface and become immobilized thereon whereas non-infected RBCs continue to flow downstream in the diagnostic channel.

  • Patent number: 8452418
    Abstract: A neural probe device includes a housing configured to receive a nerve fiber of a subject and an anchor disposed within the housing and configured to fix the nerve fiber relative to the housing. The device further includes a plurality of actuatable, moveable electrodes disposed in the housing along a length of the nerve fiber, each moveable electrode comprising a plurality of projections containing one or more electrodes thereon, wherein actuation of the moveable electrode causes the moveable electrode to move generally transverse to a long axis of the nerve fiber and penetrate the nerve fiber with the plurality of projections. The device is also optionally configured to inject a growth factor into the nerve fiber to maintain the viability of the nerve fiber.

  • Patent number: 5447068
    Abstract: A capacitive accelerometer includes electrode plates supported and aligned for movement in the direction of a substrate in which they are supported. Preferably, the plates are formed a surface micro machining, and each plate includes capacitor forming surfaces aligned at an acute angle with respect to each other. In addition, each capacitive accelerometer is formed as a differential capacitor so that one movable plate is disposed between to relatively stationary plates and a plurality of stationary and movable plates are aligned in a series along a portion of the substrate. The suspension comprises a cantilevered support arrangement for the plates.

  • Patent number: 5353641
    Abstract: A digital capacitive accelerometer is disclosed as having a fixed plate mounted on a support member and a sprung plate resiliently mounted in spaced relationship to the fixed plate to form a capacitor. A voltage is connected across the plates to establish an electrostatic force that pulls the sprung plate toward the fixed plate. The voltage is incrementally increased, pulling the sprung plate incrementally toward the fixed plate. When a pull-in voltage level is reached, the electrostatic force is of sufficient magnitude to abruptly pull the sprung plate across the remaining distance separating it from the fixed plate, and a pull-in detection signal is generated by detecting a current pulse as the gap collapses. The plates are then released, and another incrementing cycle is initiated. The pull-in voltage is a function of the initial capacitor gap which in turn is determined by the acceleration the device is experiencing.
