Patent number: 9240845Abstract: A system is provided for intercepting signals transmitted between a target served by a fiber optic network and a subscriber. A network is described having a phone switch at a central office configured to receive signals for transmission to and from a target, such as the target of a criminal investigation. A signal received at the central office is assigned to an analog circuit, and a monitoring device configured to intercept and monitor the signal is installed along the analog circuit at a location that allows the monitoring of communications without notifying the target that he is under surveillance. After the signal has been monitored, it is converted to a digital signal for transmission. A method is also provided for intercepting a signal transmitted between the target served by a fiber optic network and a subscriber, such that a monitoring device may be installed without alerting the target.Type: GrantFiled: January 18, 2012Date of Patent: January 19, 2016Assignee: VERIZON PATENT AND LICENSING INC.Inventors: Robert A. Quan, James C. Jones, Karen J. Jackson, Dagmar D. Mayor, Rosa M. Underwood

Patent number: 8990280Abstract: In some embodiments, a data processing system including an operation unit including circuitry configurable to perform any selected one of a number of operations on data (e.g., audio data) and a configuration unit configured to assert configuration information to configure the operation unit to perform the selected operation. When the operation includes matrix multiplication of a data vector and a matrix whose coefficients exhibit symmetry, the configuration information preferably includes bits that determine signs of all but magnitudes of only a subset of the coefficients. When the operation includes successive addition and subtraction operations on operand pairs, the configuration information preferably includes bits that configure the operation unit to operate in an alternating addition/subtraction mode to perform successive addition and subtraction operations on each pair of data values of a sequence of data value pairs.Type: GrantFiled: November 14, 2006Date of Patent: March 24, 2015Assignee: Nvidia CorporationInventors: Partha Sriram, Robert Quan, Bhagawan Reddy Gnanapa, Ahmet Karakas

Patent number: 7760982Abstract: A mounting structure is disclosed in a test-bed installation in which vertically aligned first backboards are pivotally secured to a front side of one of the upright posts of a relay rack for movement between a closed position and open positions. Vertically aligned second backboards are secured to a rear side of both upright posts of the relay rack in opposed relationship with the first backboards. A pair of optical network terminals is mounted on an outer side of each of the backboards, and a pair of battery backup units is mounted on an inner side thereof. Thus when one of the first backboards is moved to an open position, access is provided to the pair of battery backup units mounted on the first backboard so moved and to the pair of battery backup units mounted on the opposing second backboard.Type: GrantFiled: December 12, 2006Date of Patent: July 20, 2010Assignee: Verizon Patent and Licensing Inc.Inventors: Robert A.

Patent number: 6922771Abstract: The present invention provides a vector floating point unit (FPU) comprising a product-terms bus, a summation bus, a plurality of FIFO (first in first out) registers, a crossbar operand multiplexor coupled, a floating point multiplier, and a floating point adder. The floating point multiplier and the floating point adder are disposed between the crossbar operand multiplexor and the product-terms and summation buses, and are in parallel to each other. The invention also provides the configuration register and the command register in order to provide flexible architecture and the capability to fine-tune the performance to a particular application. The invention performs the multiplication operation and the addition operation in a pipelined fashion. Once the pipeline is filled, the invention outputs one multiplication output and one addition output at each clock cycle.Type: GrantFiled: April 24, 2002Date of Patent: July 26, 2005Assignee: PortalPlayer, Inc.Inventors: Jason Seung-Min Kim, Robert Quan
