Patent number: 8634503Abstract: A clock-data recovery system and method promotes fast adjustment to large phase changes in the incoming data signal. The system can include phase alignment circuitry, clock generator circuitry, time-to-digital converter circuitry, and sampling circuitry. The phase alignment circuitry uses the incoming data signal and a feedback clock signal to generate an output clock signal. The clock generator circuitry uses the output clock signal to generate base phase clock signals of different phases or polarities. The time-to-digital converter circuitry uses the base phase clock signals and the incoming data signal to generate the feedback clock signal. The time-to-digital converter circuitry bases the feedback clock signal on the base phase clock signal that is aligned more closely in phase with the incoming data signal than the other base phase clock signals. The sampling circuitry re-times or recovers the data signal using one or more of the base phase clock signals.Type: GrantFiled: March 31, 2011Date of Patent: January 21, 2014Inventors: Brian J. Misek, Robert K. Barnes, Peter J. Meier

Patent number: 8253810Abstract: An imaging pixel array and associated method and system are disclosed in which the array contains first pixels each having a first photo-conversion device, and second pixels each having a first photo-conversion device and a second photo-conversion device. The first photo-conversion devices are configured to acquire an image during a first integration period. The second photo-conversion devices are configured to acquire a plurality of images during the first integration period.

Patent number: 6657184Abstract: A mouse for navigating upon grainy surfaces is equipped with at least two optical navigation circuits having different views of the work surface and whose axes may be non-parallel. For each navigation circuit an indication of navigation impairment owing to grain is detected. A suitable algorithm chooses from among the various navigation circuits which one's output to use. The multiple optical navigation circuits can each be separate self-contained mechanisms on separate dies or they can be separate sections of a single integrated circuit. The various metrics used within a navigation circuit for spatial filter selection can be further used by the navigation circuit selection algorithm. Each optical navigation circuit can have its own light source, or they can share a common one. They may also share any imaging optics, although each navigation sensor sees a different image.Type: GrantFiled: October 23, 2001Date of Patent: December 2, 2003Assignee: Agilent Technologies, Inc.Inventors: Mark A Anderson, Brian J.

Patent number: 6649899Abstract: Sampling systems and methods that enable a photodetector to be sampled and read concurrently are described. This scheme may be used to implement a photocell in which image data from the photodetector may be collected during readout. In this way, the substantial non-integration periods that often characterize sampling schemes in which the sampling and readout functions are performed sequentially, especially when operating in a shuttered, non-rolling imaging mode, may be avoided.Type: GrantFiled: November 19, 2001Date of Patent: November 18, 2003Assignee: Agilent Technologies, Inc.Inventor: Brian J.

Patent number: 6593560Abstract: A photoelement for an image sensor is described which does not require a charge-to-voltage conversion, but instead outputs a voltage directly related to the intensity of the light impinging on the photoelement. In one embodiment, only parasitic capacitance is used for the integrating function. A transistor connected in a source follower configuration couples the parasitic capacitance to a read transistor. The source follower shields the integrating capacitance from any other parasitic capacitances not intended to be part of the integrating capacitance, thus making the output of the photoelement highly accurate with high gain.Type: GrantFiled: March 16, 2001Date of Patent: July 15, 2003Assignee: Agilent Technologies, Inc.Inventor: Brian J. Misek
