The method further includes selecting individual grasp patterns of the grasp pattern set having a grasp quality score that is greater than the grasp quality threshold, and providing the selected individual grasp patterns to the robot for on-line manipulation of the target object. | 07-18-2013 |

| 20090060107 | Data sampling circuit and method for clock and data recovery - A clock and data recovery circuit and method are used in a digital data communications system. The circuit and method are effectively employed for high speed, burst-mode transmission and allow rapid recovery of the clock and data signals without the need for an extended header, and notwithstanding the presence of substantial timing jitter. The method adaptively selects from among three delay times for the extraction of data by identifying a frequently recurring incoming pattern in the incoming data. The delay time is selected in a manner that insures that the same pattern is present in the reconstructed, resynchronized output data. | 03-05-2009 |
| 20110026922 | Optical fiber network with improved fiber utilization - A passive optical network system and method in which at least part of the data is optically transmitted through a single optical fiber using a wavelength division multiplexing technique, with a plurality of signals being carried through the fiber in each direction, a different wavelength being used for each of the multiplexed upstream and downstream signals. The system may be retrofitted into existing telecommunications system to provide a multi-fold increase in the available bandwidth of long-distance optical fiber transmission. | 02-03-2011 |
| 20110044685 | Optical network unit having automatic shutdown - An optical network unit useful in a passive optical network has capability for automatic shutdown upon detection of a malfunction, thereby protecting the integrity of upstream data transmitted in the network. The unit detects the generation of upstream light during intervals in which transmission is not authorized. In response, the light source of the unit is deactivated to prevent collisions with upstream data from other optical network units in the network. | 02-24-2011 |
| 20130071127 | Two way burst mode digital optical cable communication system - A digital burst mode communication system operates at a fixed wavelength for transmission and reception of burst mode signals using a pair of transceivers and a single optical cable. The stray noise level in the system is significantly reduced by use of angled plate absorbers that receive scattered transmission burst signal from a 45 degree partially reflecting mirror. Isolation of received burst signal from transmitted burst signal is increased to better than 30 dB. The system operates by sending only data bits across the single optical cable without scrambling or encoding preambles, significantly improving the efficiency of high speed communication. | 03-21-2013 |
| 20140321861 | Two way burst mode digital optical cable communication system - A digital burst mode communication system operates at a fixed wavelength for transmission and reception of burst mode signals using a pair of transceivers and a single optical cable. The stray noise level in the system is significantly reduced by use of angled plate absorbers that receive scattered transmission burst signal from a 45 degree partially reflecting mirror. Use of transparent glass ferrule with or without a front surface anti-reflection coating instead of an opaque ceramic ferrule to support optical fiber at a selected location within the transreceiver reduces optical detector signal noise. Isolation of received burst signal from transmitted burst signal is increased to better than 30 dB. The system operates by sending only data bits across the single optical cable without scrambling or encoding preambles, significantly improving the efficiency of high speed communication. | 10-30-2014 |
