| 20100117380 | DOOR KNOB ASSEMBLY - A door knob assembly having an access device operable to lock and unlock a door from a door frame. The door knob assembly device includes a spindle and the inner and outer knobs are operatively attached to the spindle. The spindle is operable to move a latching member between a first and second position so as to engage and disengage the door frame. The door knob assembly includes a locking member and a biasing member biasing the locking member so as to engage the rosette and fix the outer knob with respect to the rosette. The door knob assembly further includes an access device operable to receive a code. The access device includes a cam assembly operable to position the cam assembly between a first cam and a second cam position when the proper code is provided so as to fix and release the outer knob relative to the rosette. | 05-13-2010 |

| 20090310665 | Methods and Systems for Digitally Processing Optical Data Signals - Digital signal processing based methods and systems for receiving electrical and/or optical data signals include electrical receivers, optical receivers, parallel receivers, multi-channel receivers, timing recovery schemes, and, without limitation, equalization schemes. The present invention is implemented as a single path receiver. Alternatively, the present invention is implemented as a multi-path parallel receiver in which an analog-to-digital converter (“ADC”) and/or a digital signal processor (“DSP”) are implemented with parallel paths that operate at lower rates than the received data signal. | 12-17-2009 |
| 20100310024 | Methods and systems for DSP-based receivers - Digital signal processing based methods and systems for receiving data signals include parallel receivers, multi-channel receivers, timing recovery schemes, and, without limitation, equalization schemes. The present invention is implemented as a multi-path parallel receiver in which an analog-to-digital converter (“ADC”) and/or a digital signal processor (“DSP”) are implemented with parallel paths that operate at lower rates than the received data signal. In an embodiment, a parallel DSP-based receiver in accordance with the invention includes a separate timing recovery loop for each ADC path. In an embodiment, a parallel DSP-based receiver includes a separate automatic gain control (AGC) loop for each ADC path. In an embodiment, a parallel DSP-based receiver includes a separate offset compensation loop for each ADC path. In an embodiment, the present invention is implemented as a multi-channel receiver that receives a plurality of data signals. | 12-09-2010 |
