The clock generator generates a clock signal, and the first board is configured to receive said clock signal. The first board further comprises a clock synchronizing unit that synchronizes a reference signal with said clock signal and generates a blink cadence signal based on said reference signal. The blink cadence signal is configured to drive the indicator of said first board. A failure by said first board to receive said clock signal causes the clock synchronizing unit of said first board to maintain the reference signal and generate said blink cadence signal based on said reference signal.Type: GrantFiled: December 11, 2009Date of Patent: August 7, 2012Assignee: Hewlett-Packard Development Company, L.P.Inventor: David Maciorowski

Patent number: 8207857Abstract: The invention relates to a detection device for piece goods, in particular textiles. Starting from the marking of textiles with RFID tags that can be read out with the use of a reader, as is known from the prior art, a detection device for textiles is produced within the scope of the present invention, in which electromagnetic fields of different orientation are generated with the use of at least two antennas arranged at a defined angle to each other, and this ensures that the electronic markings of the piece goods disposed in a counting cage may be reliably read out independently of their relative arrangement in the space.Type: GrantFiled: October 26, 2005Date of Patent: June 26, 2012Assignee: VERMOP Salmon GmbHInventor: Lutz Schneider

Patent number: 8138918Abstract: An intrusion detection and tracking system includes a plurality of nodes, a DP and a gateway. The nodes are disposed about an area and form a wireless network to be monitored, the nodes are configured to receive data and transmit data frames with a signal strength indicator and/or a link quality indicator in the frames. The DP is communicatively connected to the network and configured to analyze variations in the signal strength indicator and/or link quality indicator to detect and track disturbances to an electromagnetic field in the area. The gateway is configured to form a data link between the network and the DP.Type: GrantFiled: September 17, 2009Date of Patent: March 20, 2012Assignee: Raytheon CompanyInventors: Toni S. Habib, Wassim S. Habib

Patent number: 8120354Abstract: A self-calibrating magnetic field monitor is disclosed. In one embodiment, a magnetic field sensor repeatedly generates an electronic signal related to the magnetic field. In addition, a calibration module generates a relative baseline signal based on an average value of the electronic signals for a given time period. A comparator compares the electronic signal with the relative baseline signal and generating an output signal if a difference in the comparing is greater than or equal to a threshold.Type: GrantFiled: April 28, 2009Date of Patent: February 21, 2012Assignee: Broadband Discovery Systems, Inc.Inventors: Cory James Stephanson, Paul Roybal

Patent number: 8098157Abstract: A zoned interactive control area (10) wherein an architectural space is divided in to a plurality of zones (16), each having its own sensor (22) and zone lights (18). In a normal operating mode (50) the sensors (22) are used to detect the presence of a person such that the zone lights (18) can be turned on and/or adjusted for light level. Each zone light (18) also has a light sensor (24) used, at least in part, for communication with the other zone lights (18), such that the light level can be adjusted not just in response to a presence in the respective zone (16) but also in response to presence in other zones (16). According to a security method (70) when the zone lights (18) are not in use for normal lighting (as when they are turned off) then if the sensors (22) detect the presence of an intruder the zone lights (18) flash to deter the intruder and also communicate the fact of the presence of the intruder to the other zone lights (18) via the light sensors (22).Type: GrantFiled: March 12, 2009Date of Patent: January 17, 2012Assignee: VNS Portfolio LLCInventors: F. Eric Saunders, Gregory V. Bailey, Nicholas A. Antonopoulos

Patent number: 8057871Abstract: This invention provides an improved anti-theft label and its assembly method. It uses paper box and paper sealing gasket to replace PVC box and PET sealing gasket. The anti-theft label applying the technical scheme of this invention is nontoxic and does no harm to human health. It can be used safely, and is the new generation of anti-theft label that is good for environment protection and represents the main developing trend of future anti-theft labels. Moreover, in the improved anti-theft label in this invention, we use double-sided gummed paper that can easily get from market to replace self-adhesive glues which needs to be sprayed. The assembling techniques are simpler; consequently the production efficiency can be significantly improved.Type: GrantFiled: May 29, 2006Date of Patent: November 15, 2011Inventor: Fengyi Cai
