*** Xilinx Assigned Patent ALEXANDRIA, Va., March 7 -- Xilinx, San Jose, Calif., has been assigned a patent (8,391,343) developed by Jerry Chuang, Sunnyvale, Calif., William C. Black, Ames, Iowa, and Scott A. Irwin, Ames, Iowa, for a "PMA RX in coarse loop for high speed sampling." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A high data rate transceiver for processing high data rate serial data includes circuitry for recovering a clock based on the high data rate input data stream.

In a sample mode of operation, only the coarse loop PLL is coupled to provide an error signal from which an oscillation signal and clock may be derived. In a second mode (lock) of operation, the transceiver may lock to the received serial data stream by coupling the fine loop PLL to provide an adjusted error signal. In a third mode of operation, (automatic) the transceiver initially performs coarse loop calibration by de-coupling the fine loop PLL and coupling the coarse loop PLL until a steady state has been reached." The patent application was filed on Oct. 7, 2008 (12/247,125).

*** Boston Scientific Neuromodulation Assigned Patent ALEXANDRIA, Va., March 7 -- Boston Scientific Neuromodulation, Valencia, Calif., has been assigned a patent (8,391,991) developed by M. Mizanur Rahman, Stevenson Ranch, Calif., Daniel J. Klostermann, Cedar Rapids, Iowa, and Daniel J. Aghassian, Los Angeles, for a "multiple telemetry and/or charging coil configurations for an implantable medical device system." The abstract of the patent published by the U.S. Patent and Trademark Office states: "An implantable medical device system for orientation-independent telemetry to and from the device are disclosed. The system includes an external controller which produces an electromagnetic field to induce a current in a coil in the implantable medical device and vise versa. In a preferred embodiment, the external controller comprises three orthogonal coils, each of which is potentially activated to generate or receive the electromagnetic field. Algorithms are disclosed to allow for the choice of one or more of the coils best suited for telemetry based on the chosen coil's orientation with respect to the telemetry coil in the implantable medical device. Because all three of the orthogonal coils are potentially activated if necessary, the result is that at least one of the coils will be in a proper orientation with respect to the coil in the implantable medical device, thereby improving telemetry or power transfer efficiency." The patent application was filed on March 19, 2012 (13/423,954). The full-text of the patent can be found at http://patft.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=8,391,991.PN.&OS=PN/8,391,991&RS=PN/8,391,991 Written by Kusum Sangma; edited by Anand Kumar.

*** Rockwell Collins Assigned Patent ALEXANDRIA, Va., March 7 -- Rockwell Collins, Cedar Rapids, Iowa, has been assigned a patent (8,391,416) developed by Timothy E. Snodgrass, Palo, Iowa, and Dennis L. Hoffman, Cedar Rapids, Iowa, for a "syncronization frequency diversity reception utilizing a single RF receiver." The abstract of the patent published by the U.S. Patent and Trademark Office states: "A system may include a receiver having a number of reception channels spread across an instantaneous radio frequency bandwidth, each one of the reception channels for receiving a different radio frequency within the instantaneous radio frequency bandwidth. The system may also include control programming for positioning the receiver on one of a number of synchronization frequencies transmitting a synchronization preamble, where a number of reception channels is less than a number of synchronization frequencies, and a probability of not receiving one or more of the synchronization frequencies is smaller than a required message error rate for receiving the plurality of synchronization frequencies."

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=8,391,416&OS=8,391,416&RS=8,391,416 Written by Arpi Sharma; edited by Anand Kumar.

*** AT&T Intellectual Property I, Iowa State University Research Foundation Assigned Patent ALEXANDRIA, Va., March 7 -- AT&T Intellectual Property I, Atlanta, and Iowa State University Research Foundation, Ames, Iowa, have been assigned a patent (8,391,164) developed by Graham Cormode, Summit, N.J., Philip Korn, New York, and Srikanta Tirthapura, Ames, Iowa, for "computing time-decayed aggregates in data streams." The abstract of the patent published by the U.S. Patent and Trademark Office states: "Aggregates are calculated from a data stream in which data is sent in a sequence of tuples, in which each tuple comprises an item identifier and a timestamp indicating when the tuple was transmitted. The tuples may arrive out-of-order, that is, the sequence in which the tuples arrive are not necessarily in the sequence of their corresponding timestamps. In calculating aggregates, more recent data may be given more weight by multiplying each tuple by a decay function which is a function of the timestamp associated with the tuple and the current time. The tuples are recorded in a quantile-digest data structure. Aggregates are calculated from the data stored in the quantile-digest data structure." The patent application was filed on Jan. 2, 2008 (12/006,338). 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=8,391,164&OS=8,391,164&RS=8,391,164 Written by Neha Bharti; edited by Jaya Anand.
