International Classification:

H03K 19173

US Classification:

326 46, 326 40, 326 50, 326 97, 327203

Abstract:

A user configurable circuit contains clock logic, a switching element and a data path circuit. Input data is received in the switching element, and the switching element and the data path circuit constitute the entire data path for the circuit. A plurality of user configurable inputs are received to configure the circuit for a particular user application. The clock logic and the switching element implement a logic function that is configurable by the user configurable inputs. The logic function is pre-processed in the clock logic so that minimal delay occurs in the data path. In addition, the propagation delay through the switching element and the register is independent of the user configurable inputs. The user configurable circuit of the present invention has application for use as a macro cell for a programmable logic device permitting the user to configure the circuit as a D-type flip-flop, a T-type flip-flop. In addition, the user selects the polarity for the output circuit.

Abstract:

A spread polarization transmitter for transmitting at least one light signal comprises a spread-spectrum communication apparatus and a polarization modulator. The spread-spectrum communication apparatus modulates the at least one light signal according to a spread-spectrum modulation technique. The polarization modulator comprises a polarizer and a magnetic bubble waveguide. The polarizer is capable of polarizing the at least one spread-spectrum modulated light signal in a polarized direction. And the magnetic bubble waveguide, which is configured in accordance with a pseudo-random polarization code sequence such that the plurality of magnetic bubble domains assume a time varying position representative of the pseudo-random polarization code sequence, is capable of receiving at least one polarized, spread-spectrum modulated light signal. Thereafter, the magnetic bubble waveguide is capable of at least partially rotating the polarized, spread-spectrum modulated light signals by a predetermined angle from the polarized direction during transmission therethrough to create spread polarization modulated light signals.

International Classification:

H01S 3/10
H01S 3/13

US Classification:

372 26, 372290011

Abstract:

A diode laser for providing a high-energy coherent light beam suitably includes an array of laser diodes, each producing a laser beamlet. The beamlets are provided to a spatial light modulator (SLM) with an array of pixels, each pixel corresponding to a portion of the light beam. The phase variation across the light beam wavefront is monitored at a detector, and a feedback signal indicative of the phase variation is provided to control electronics. The control electronics process the feedback signal to modulate a local index of refraction within one or more pixels of the SLM to reduce the variation in phase across the beam wavefront. Because phase variations across the beam wavefront are reduced, relatively large diode arrays can be formulated, thereby resulting in relatively high powered diode lasers.

US Classification:

345 30, 345 86, 385 1, 385 4, 385 6

Abstract:

Systems and methods are disclosed for providing a more robust flat panel display by using the Faraday effect to control light emission from a solid state material so as to form two-dimensional or three-dimensional images. Flux tubes can be configured to define a two dimensional array. Each flux tube is somewhat analogous to a single bubble of a magnetic bubble memory and can define a pixel. At least some aspect of light transmitted through a flux tube can be varied thereby, so as to facilitate the formation of an image.
