Patent number: 8628972Abstract: 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.Type: GrantFiled: January 10, 2012Date of Patent: January 14, 2014Assignee: The Regents of the University of CaliforniaInventors: William C. Tang, Yu-Hsiang Hsu

Patent number: 5447068Abstract: 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.Type: GrantFiled: March 31, 1994Date of Patent: September 5, 1995Assignee: Ford Motor CompanyInventor: William C. Tang

Patent number: 5353641Abstract: 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.Type: GrantFiled: August 7, 1992Date of Patent: October 11, 1994Assignee: Ford Motor CompanyInventor: William C.
