QUALCOMM Assigned Patent for Transmit Diversity and Spatial Spreading for an OFDM-based Multi-antenna Communication System
ALEXANDRIA, Va., May 4 -- QUALCOMM, San Diego, has been assigned a patent (8,169,889) developed by five co-inventors for a "transmit diversity and spatial spreading for an OFDM-based multi-antenna communication system." The co-inventors are J. Rodney Walton, Carlisle, Mass., John W. Ketchum, Harvard, Mass., Mark S. Wallace, Bedford, Mass., Steven J. Howard, Ashland, Mass., and Sanjiv Nanda, Ramona, Calif.
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A multi-antenna transmitting entity transmits data to a single- or multi-antenna receiving entity using (1) a steered mode to direct the data transmission toward the receiving entity or (2) a pseudo-random transmit steering (PRTS) mode to randomize the effective channels observed by the data transmission across the subbands. The PRTS mode may be used to achieve transmit diversity or spatial spreading. For transmit diversity, the transmitting entity uses different pseudo-random steering vectors across the subbands but the same steering vector across a packet for each subband. The receiving entity does not need to have knowledge of the pseudo-random steering vectors or perform any special processing. For spatial spreading, the transmitting entity uses different pseudo-random steering vectors across the subbands and different steering vectors across the packet for each subband. Only the transmitting and receiving entities know the steering vectors used for data transmission."
The patent application was filed on March 5, 2004 (10/794,918). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,169,889&OS=8,169,889&RS=8,169,889

Bourns Assigned Patent
ALEXANDRIA, Va., May 4 -- Bourns, Riverside, Calif., has been assigned a patent (8,169,763) developed by Andrew J. Morrish, Saratoga, Calif., for a "transient blocking unit having an enhancement mode device in the primary current path."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A transient blocking unit (TBU) is a circuit having series-connected transistors that normally conduct current, but automatically switch to a high-impedance current blocking state in response to an over-current condition. Here enhancement mode devices are used in the primary TBU current path, as opposed to the conventional use of depletion mode devices in this context. This approach provides two main advantages. The first advantage is that the dependence of TBU parameters on poorly controlled depletion mode device parameters can be reduced or eliminated. The second advantage is that such TBUs can provide over-voltage protection in addition to over-current protection."

SanDisk Technologies Assigned Patent for Data State-dependent Channel Boosting to Reduce Channel-to-floating Gate Coupling in Memory
ALEXANDRIA, Va., May 4 -- SanDisk Technologies, Plano, Texas, has been assigned a patent (8,169,822) developed by Deepanshu Dutta, Santa Clara, Calif., Jeffrey W. Lutze, San Jose, Calif., and Grishma Shah, San Jose, Calif., for a "data state-dependent channel boosting to reduce channel-to-floating gate coupling in memory."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "In a programming operation, selected storage elements on a selected word line are programmed while unselected storage elements on the selected word line are inhibited from programming by channel boosting. To provide a sufficient but not excessive level of boosting, the amount of boosting can be set based on a data state of the unselected storage element. A greater amount of boosting can be provided for a lower data state which represents a lower threshold voltage and hence is more vulnerable to program disturb. A common boosting scheme can be used for groups of multiple data states. The amount of boosting can be set by adjusting the timing and magnitude of voltages used for a channel pre-charge operation and for pass voltages which are applied to word lines. In one approach, stepped pass voltages on unselected word lines can be used to adjust boosting for channels with selected data states."
The patent application was filed on Nov. 11, 2009 (12/616,269). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,169,822&OS=8,169,822&RS=8,169,822

According to one technique, a master node is appointed in a cluster. Other "slave" nodes periodically synchronize their clocks with the master node. To synchronize its clock with the master node, a slave node sends a timestamped message to the master node, which also timestamps the message and sends the message back to the slave node, which then timestamps the message again. Based on the timestamps, the slave node is able to determine the difference between the master node's clock's time and slave node's clock's time, compensating for the message travel time between master node and slave node. Depending on various circumstances, and based on the determined difference, the slave node adjusts its clock so that the time indicated by the slave node's clock at least begins to approach more closely the time indicated by the master node's clock."

Doubleshot Assigned Patent
ALEXANDRIA, Va., May 4 -- Doubleshot, Santa Rosa, Calif., has been assigned a patent (8,169,445) developed by Miles L. Scott, Rohnert Park, Calif., for "methods and systems for full-color three-dimensional image display."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "Methods and systems for displaying full-color three-dimensional imagery are provided. A first color set, having a first color spectrum, is defined to include a first set of LEDs. The first color set is assigned to a first color-coded image perspective. A second color set, having a second color spectrum, is defined to include a second set of LEDs. The second color set is assigned to a second color-coded image perspective. The full-color three-dimensional imagery is caused by activating, alternatively, at least two LEDs of the first color set or the second color set and one LED of a remaining color set and displaying the three-dimensional image based on the first image perspective and the second image perspective."
The patent application was filed on Oct. 1, 2008 (12/243,704). The full-text of the patent can be found at http://patft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=8,169,445.PN.&OS=PN/8,169,445&RS=PN/8,169,445

USDA Assigned Patent
ALEXANDRIA, Va., May 4 -- The U.S. Department of Agriculture has been assigned a patent (8,169,483) developed by Elaine Backus, Clovis, Calif., and William H. Bennett, Otterville, Mo., for a "system and method for synchronizing waveform data with an associated video."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A subject is connected to a monitoring system and videoed while being monitored. The monitoring system receives raw data from the subject and processes the raw data into waveform data, and transmits the waveform data to a marking device. The marking device simultaneously marks the waveform data with a waveform reference point and causes a light emitting diode to flash in the video, thereby creating a video reference point. A computer program locks the waveform reference point with the video reference point and thereby synchronizes the waveform data with the video."
The patent application was filed on Oct. 3, 2008 (12/245,022). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,169,483&OS=8,169,483&RS=8,169,483
