Patent number: 7529561Abstract: The invention enables a reliable end-to-end monitoring system by means of which the location of containers and other conditions related to the containers can be continuously or almost continuously monitored. The containers are equipped with such container units that are capable to co-operate with each other, which is especially needed in challenging radio environments. The co-operation of the container units is based on mesh network algorithms. Each container unit placed in a container includes a short range radio and a cellular network radio. Thus, the container unit is able to connect to two different types of communication networks. In addition, each container unit uses a certain connection set-up logic. When a set-up attempt results in a connection, the container transmits its message through the connection. The invention comprises the container unit, a mesh network composed of container units, and a system reporting container events.Type: GrantFiled: August 31, 2006Date of Patent: May 5, 2009Inventors: Tero Heinonen, Pauli Noronen

Patent number: 7496343Abstract: A state of a programmable mixer is set during a calibration phase to minimize local oscillator feedthrough. During a calibration phase, inputs to the programmable mixer are set to zero, or to a known state and the local oscillator is set to a calibration frequency. Then, one of a plurality of known calibration states of the programmable mixer is entered and the local oscillator feedthrough is measured. For each of a plurality of operating states an amplified output of the programmable mixer is measured. In one operation, the state of the programmable mixer in which the programmable mixer operates during a next operation phase is the state that produces minimal local oscillator feedthrough. In another operation, operation continues until a state is found that produces a local oscillation feedthrough that meets an operating criteria and that state is used during the next operation phase.Type: GrantFiled: September 19, 2005Date of Patent: February 24, 2009Assignee: Broadcom CorporationInventor: Shahla Khorram

Patent number: 7483683Abstract: Rejection of local oscillator harmonic response is provided in a mixing circuit with a pair of harmonic gating switches serially connected to the outputs of a balanced differential switching mixer and controlled by a gate clock signal having twice the frequency of a local oscillator signal controlling the switching mixer. An aperture or duty cycle of the gate clock signal determines which harmonic is rejected or suppressed, which is preferably a third and/or fifth harmonic since response of the balanced differential switching mixer to even harmonics is negligible. The resulting simple, efficient circuit is readily integrated directly into a phase-alternating mixer structure for a chopper-direct-conversion radio.Type: GrantFiled: August 3, 2007Date of Patent: January 27, 2009Assignee: National Semiconductor CorporationInventors: Hee Wong, Michael Schwartz, James Braatz, Shu-Ing Ju

Patent number: 7477876Abstract: A channel quality feedback method for wireless transmission is described in which the rate for reporting channel quality information from a mobile station to a base station is variable as a function of the presence or absence of a transmission from the base station to the mobile station. In particular, the feedback rate from the mobile station to the base station is increased when the mobile station detects a transmission from the base station. As such, the feedback rate is slower when there is no data transmission for the mobile station and faster when the mobile station is receiving data.Type: GrantFiled: November 2, 2001Date of Patent: January 13, 2009Assignee: Alcatel-Lucent USA Inc.Inventors: Amab Das, Farooq Ullah Khan
