20100149040 | METHOD FOR GENERATING A LOCATION SIGNAL - A communication device uses its FGU to generate a location signal that can be used by a reference device to calibrate the communication device and to determine the distance of the communication device from the reference device. The communication device: receives, from a reference device, at least one location signal control parameter that defines pulse shape characteristics for a location signal; configures its FGU based on the at least one location signal control parameter; generates a linear first part of a phase-incoherent location signal having the defined pulse shape characteristics by progressively sweeping an output of the FGU over a range of frequencies from a first frequency to a second frequency within a first time period; and transmits at least one iteration of the first part of the location signal. | 06-17-2010 |
20100150209 | METHOD AND DEVICE FOR GENERATING A LOCATION SIGNAL - A frequency generation unit (FGU) in a communication device includes a voltage controlled oscillator (VCO), an adjustable filter having a capacitive element for wideband operation, a current source with variable gain, and chirp generation control circuitry (CGC) that is used to generate location signals. The FGU receives, from a reference device, at least one location signal control parameter that defines linear frequency slope characteristics for a location signal. The CGC configures, based on the at least one location signal control parameter, the gain and a polarity of the current source to generate a first current during a first time period for charging the capacitive element to generate a control signal that is coupled to the VCO to generate a first part of the location signal having the defined linear frequency slope characteristics, wherein the first part of the location signal is transmitted using a transceiver of the communication device. | 06-17-2010 |
20100151886 | METHOD AND APPARATUS FOR DETERMINING LOCATION OF A COMMUNICATION DEVICE - A reference device determines its distance from a communication device by first using a training process to determine a calibrated time delay for the communication device when the communication device is at a known distance from the reference device, wherein the calibrated time delay comprises a steady state internal processing delay for the communication device. Subsequently, when the reference device is at an unknown distance from the communication device, the reference device determines the unknown distance using the previously determined calibrated time delay. | 06-17-2010 |
20120004782 | METHODS FOR MANAGING POWER CONSUMPTION IN A SENSOR NETWORK - Methods for reducing sensor support power in a sensor network include a primary node locating a secondary node. The primary node has a primary node sensor profile, and the secondary node has a secondary node sensor profile. The secondary node sensor profile is compared to the primary node sensor profile. A virtual sensor profile is constructed based on the comparison between the primary and secondary sensor profiles. The virtual sensor profile reduces redundant sensor data gathering between the primary and secondary sensor nodes. A power consumption optimization hardware configuration for the secondary node is determined to provide sensor data for the virtual sensor profile, and the determined hardware configuration is assigned to the secondary node. | 01-05-2012 |
20150016554 | CONTEXT AWARE MULTIPLE-INPUT AND MULTIPLE-OUTPUT ANTENNA SYSTEMS AND METHODS - A method, a system, and a server provide context aware multiple-input-multiple-output MIMO antenna systems and methods. Specifically, the systems and methods provide, in a multiple MIMO antenna or node system, techniques of antenna/beam selection, calibration, and periodic refresh, based on environmental and mission context. The systems and methods can define a context vector as built by cooperative use of the nodes on the backhaul to direct antennas for the best user experience as well as mechanisms using the context vector in a 3D employment to point the antennas in a cooperative basis therebetween. The systems and methods utilize sensors in the nodes to provide tailored context sensing versus motion sensing, in conjunction with BER (Bit Error Rate) measurements on test signals to position an antenna beam from a selection of several “independent” antenna subsystems operating within a single node, as well as, that of its optically connected neighbor. | 01-15-2015 |
