Patent number: 9285338Abstract: Systems, devices, and methods are presented that facilitate electronic manipulation and detection of submicron particles. Time-multiplexed dielectrophoresis can be employed by cycling between two or more disparate electric fields during separate portions of a duty cycle. By cycling between these two or more disparate electric fields, two or more disparate particle types can be separated from one another based on differences in electrical properties of the two or more disparate particle types.Type: GrantFiled: December 13, 2012Date of Patent: March 15, 2016Assignee: UNIVERSITY OF PITTSBURGH—OF THE COMMONWEALTH SYSTEM OF HIGHER EDUCATIONInventors: Samuel J.

Patent number: 8815071Abstract: Systems, devices, and methods are presented that facilitate electronic manipulation and detection of submicron particles. A particle manipulation device contains a plurality of electrodes formed on an active semiconductor layer of an integrated circuit chip, where the electrodes and gap spacing between adjacent electrodes is submicron in size. The chip is oriented with its substrate face up, and at least a portion of the substrate is removed from the chip so the electrodes are in close proximity to a fluid chamber(s) placed over the chip, to facilitate manipulation of particles, contained in a buffer solution in the fluid chamber(s), to form a defined pattern. Innovative macro-scale optical detection is employed to detect the submicron particles, where a light beam is applied to the defined pattern, and interaction of the defined pattern with the light beam is detected and evaluated to facilitate detecting the particles.Type: GrantFiled: August 28, 2012Date of Patent: August 26, 2014Assignee: University of Pittsburgh—Of the Commonwealth System of Higher EducationInventors: Steven P.

Patent number: 7358869Abstract: A low-power, area and pin efficient signaling alternative to serial differential links used for chip-to-chip, backplane, optical and other signaling applications. The multi-bit differential signaling (MBDS) generally comprises a driver and link termination network design coupled with a coding system based on n choose M (nCm) coding. MBDS has comparable electrical characteristics to conventional low-voltage differential signaling (LVDS) and is fully compatible with existing LVDS receivers in point-to-point and multi-point bus topologies. However, MBDS uses up to 40% less power, with up to 33% fewer I/O pads than equivalent LVDS links.Type: GrantFiled: August 20, 2004Date of Patent: April 15, 2008Assignee: University of PittsburghInventors: Donald M.

Patent number: 4883334Abstract: The present invention pertains to an optical selector switch. The optical selector switch includes an optical waveguide means, and M means for producing light that can be transmitted through the optical waveguide means with M being greater than or equal to 2. The M light producing means are optically connected to the optical waveguide means. The optical selector switch includes means for controlling when each of the M light producing means produces optical pulses to be transmitted through the optical waveguide means. Additionally, there are N optical transduces optically connected to the optical waveguide means, with N being greater than or equal to 2. Each of the N optical transducers are capable of producing an electrical signal corresponding to the combination of optical pulses received from the M light-producing means. The N optical transducers can be arranged in either a one, two or three dimensional array. Moreover, memory cells can be included to provide for a memory array.Type: GrantFiled: November 30, 1987Date of Patent: November 28, 1989Assignee: The University of PittsburghInventors: Donald M.
