20130021081 | CIRCUITRY AND METHOD FOR DIFFERENTIAL SIGNAL DETECTION WITH INTEGRATED REFERENCE VOLTAGE - Differential signal detection circuitry with an integrated reference voltage. The reference voltage is added as an offset to the output voltage, and its integration ensures that variations in the reference voltage closely track variations in the signal. Accordingly, the detection threshold for the signal being detected remains more consistent over variations in the circuit manufacturing process, power supply voltage and operating temperature. | 01-24-2013 |
20130021082 | LOW VOLTAGE DIFFERENTIAL SIGNALING (LVDS) CIRCUITRY AND METHOD FOR DYNAMICALLY CONTROLLING COMMON MODE VOLTAGE AT INPUT - Low voltage differential signaling (LVDS) circuitry and method for dynamically controlling the common mode voltage at the input of an LVDS receiver. The common mode voltage of the incoming LVDS signal is monitored. The common mode voltage at the input of the LVDS receiver is clamped at a clamp voltage when the common mode voltage of the incoming LVDS signal is less than a predetermined voltage, and allowed to track it otherwise. | 01-24-2013 |
20130021186 | CIRCUITRY AND METHOD FOR DIGITAL TO ANALOG CURRENT SIGNAL CONVERSION WITH PHASE INTERPOLATION - Circuitry and method for digital-to-analog current signal conversion with phase interpolation. For an n-bit digital-to-analog converter (DAC), the number 2 | 01-24-2013 |
20130188762 | Clock Data Recovery With Out-Of-Lock Detection - The disclosed clock-data recovery architecture includes out-of-lock (including false lock) detection. Out-of-lock detection is accomplished by sampling retimed/recovered data with positive and negative edges of the received data. In example embodiments, an out-of-lock condition is determined either by detecting the occurrence of, or counting, missed edges corresponding to the failure of received data sampling to detect corresponding positive/negative edges of the retimed/recovered data. | 07-25-2013 |

20100145014 | SYSTEM AND PROCESS FOR THE SYNTHESIS OF POLYMERS - The present invention relates to an automated polymer synthesis apparatus for synthesizing a polymer chain onto a solid substrates by sequentially adding polymer building blocks as well as to a method for synthesizing polymers on solid substrates by sequentially reacting polymer building blocks with reactive groups. The invention further relates to a biochip comprising a solid substrate with reactive groups where biomolecules are attached to and the remaining reactive groups are transformed into chemically inert species. | 06-10-2010 |
20120176446 | MULTICOLOR PRINTHEAD MAINTENANCE STATION - A maintenance station apparatus for an ink jet printhead is provided. The printhead includes a plurality of jetting modules disposed side by side in a row and inclined relative to a direction of print media motion, each of the plurality of jetting modules including a nozzle face, each nozzle face including a first nozzle array configured to eject a first liquid and a second nozzle array configured to eject a second liquid. The maintenance station apparatus includes a wiping unit including a first wiper, a second wiper, and a wiper moving mechanism, the first wiper being associated with the first nozzle array of each jetting module and the second wiper being associated with the second nozzle array of each jetting module, and a capping unit including a plurality of cap pairs corresponding to the plurality of jetting modules, one cap of each cap pair being associated with the first nozzle array of the corresponding jetting module, the other cap of the cap pair being associated with the second nozzle array of the corresponding jetting module. | 07-12-2012 |
