Patent number: 8941495Abstract: According to some example embodiments, systems, apparatus, methods, computer readable media, and computer program products are provided for implementing a wireless shelf pusher activity detection system. One example apparatus is a monitoring device for monitoring theft or sales activity associated with a product pusher device. The monitoring device may include a sensor configured to detect movement of a pusher member of the product pusher device, a wireless communications interface, and a processor. The processor may be configured to receive at least one sensor signal from the sensor indicating movement of the pusher member, determine a product movement activity type based on characteristics of the at least one sensor signal, and generate, for transmission via the wireless communications interface, a pusher activity message indicating the product movement activity type.Type: GrantFiled: June 11, 2012Date of Patent: January 27, 2015Assignee: Checkpoint Systems, Inc.Inventors: Brian Wiese, David Christianson, Mark Shafer

Patent number: 8472533Abstract: A noise cancellation system has a first transformer with an input side and an output side, the input side having first and second taps coupled to a signal provider, and a center tap providing a first common-mode voltage signal. A first digital subscriber line (xDSL) modem has an input coupled to the output side of the first transformer and an output coupled to customer premises equipment (CPE) for providing an xDSL signal to the CPE. A second transformer has an input side and an output side, the input side having first and second taps coupled to a signal provider, and a center tap providing a second common-mode voltage signal. A second xDSL modem is coupled to the output side of the second transformer. The difference between the first and second common-mode voltage signals is provided to at least one of the first and second xDSL modems to filter out noise from the xDSL signal provided by that modem.Type: GrantFiled: May 2, 2011Date of Patent: June 25, 2013Assignee: Broadcom CorporationInventor: Brian Wiese

Patent number: 8378823Abstract: An anti-theft security system that utilizes an electronic article surveillance (EAS) beacon that emits an electromagnetic field that a corresponding security tag transponder detects in determining whether to set off onboard transponder alarms or to remain dormant. The EAS beacon is a self-contained beacon that can be easily installed at any desired location and can utilize local utility power or revert to battery power. Among other things, this avoids the large installation, calibration and maintenance costs and tasks of conventional EAS pedestals. The EAS beacon includes coil panels that are secured to an elongated housing that can be flexed to avoid or minimize damage should something or someone come into contact with the panels. An audible/visible alarm is activated when such flexing or tampering occurs. A passive infrared detector is provided to reduce power consumption when the EAS beacon is operating on battery power.Type: GrantFiled: April 30, 2010Date of Patent: February 19, 2013Assignee: Checkpoint Systems, Inc.Inventors: Lee Eckert, Brian Vincent Conti, Gary Mark Shafer, Brian Wiese

Patent number: 8194722Abstract: Methods and apparatuses for reducing effects of impulse noise in a DSL transmitter receiver device are described. According to certain embodiment, the method includes using a periodicity associated with the impulse noise affecting a DSL transmitter receiver device to determine data frames that are affected by the impulse noise, and sending a reduced data rate during those frames. In certain embodiments, no data is sent during those frames. The method further includes using a high margin bits and gain table, instead of a normal bits and gain table.Type: GrantFiled: October 11, 2005Date of Patent: June 5, 2012Assignee: Broadcom CorporationInventors: Andrew L. Norrell, Hossein Sedarat, Kevin D. Fisher, Douglas J. Artman, James T. Schley-May, Brian Wiese

Patent number: 7953163Abstract: A method and apparatus for channel equalization in a multi-carrier communication system. The method may include receiving a symbol having multiple sub-carriers and reducing an error on at least one of the sub-carriers of the symbol by adding to it, one or more weighted multiples of other sub-carriers. The added weighted multiples may be from neighboring sub-carriers in the same symbol and/or from other symbols in a tone, for example, a previous or next symbol. The apparatus may include a reduced-complexity block linear equalizer.Type: GrantFiled: May 16, 2005Date of Patent: May 31, 2011Assignee: Broadcom CorporationInventor: Brian Wiese

Patent number: 6434119Abstract: A variety of methods of initializing a connection between a remote modem and a central unit in a communication system that utilizes a multi-carrier modulation scheme are described. In one aspect of the invention, a relatively long duration single frequency activation signal that ramps up and ramps down in intensity is utilized. In a preferred embodiment, the activation signal is transmitted on a sub-carrier that is outside a range of sub-channels used for data transmission in the multi-carrier modulation scheme. In a separate aspect of the invention, an initialization sequence that includes central synchronization signal, a remote synchronization signal, a central setup signal, a remote setup signal, a central setup complete signal a remote message and a central message. The central unit transmits a central setup complete signal when it has completed a central setup procedure.Type: GrantFiled: July 7, 1998Date of Patent: August 13, 2002Assignee: Texas Instruments IncorporatedInventors: Brian Wiese, Krista Jacobsen, Nicholas P.

Patent number: 6205220Abstract: The present invention provides methods and apparatuses for reducing near-far cross-talk interference between channels in a communication system. Channels of different lengths that are disposed adjacent to each other and carrying signals at the same frequencies often time create cross-talk interference in their neighboring channels. By spectrally shaping the signals carried on shorter lines the amount of cross-talk interference generated by these lines to longer lines may be significantly reduced, resulting in a better overall performance. In one embodiment of the present invention, a method of reducing the generation of near-far cross-talk interference includes spectrally shaping a signal carried on a first channel to reduce the amount of cross-talk coupling a neighboring second channel. In further embodiments, the shaping of the signal carried on the first channel is based in part on characteristics of the second and/or first channel.Type: GrantFiled: August 13, 1998Date of Patent: March 20, 2001Assignee: Texas Instruments IncorporatedInventors: Krista S.
