A method to perform convolutions between arbitrary vectors includes estimating a first degree of match for a difference between a first vector having a plurality of first elements and a second vector having a plurality of second elements using a first cluster of coupled oscillators, estimating a second degree of match for the first vector using a second cluster of coupled oscillators, estimating a third degree of match for the second vector using a third cluster of coupled oscillators, deriving a first squared Lnorm from the first degree of match, deriving a second squared Lnorm from the second degree of match, deriving a third squared Lnorm from the third degree of match, adding the second squared Lnorm and the third squared Lnorm, and subtracting the first squared Lnorm to form a sum, and dividing the sum by two.

Method to perform convolutions between arbitrary vectors using clusters of weakly coupled oscillators

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.

Separation of particles using multiplexed dielectrophoresis

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.

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.

Power efficient, high bandwidth communication using multi-signal-differential channels

Multipath structures formed from coherent fiber bundle structures for interconnecting a number of opto-electronic devices in a compact space. The coherent fiber bundle structures are formed from fiber optic plates and have different geometries and fiber orientations in order to transmit optic signal between opto-electronic device in different locations.

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.
