摘要： Systems and methods are disclosed for the use of sensor links in a network to estimate the breathing rate of a breathing subject within a structure, estimate the location of the subject within the structure, and detect if the subject is breathing. The structure may be a bed, a building, or a room in the building. The received signal strength of the sensor links is obtained and is then used in various breathing models to determine the breathing rate estimation, the location estimation, and the breathing detection.

摘要： A method is provided for estimating relative location information for wireless devices. Individual estimates are obtained from two or more alternative means that determining the relative location, such as range information, of first and second wireless devices with respect to each other (710, 720, 910, 920). At least one of these estimates involves an estimate of relative location between one of the first and second devices and a third device. These estimates are combined to provide a new estimate that is statistically more accurate than any one of the individual estimates (740, 940).

摘要： A technique for intra-piconet location determination and tomography is described. This technique uses received signal strength indicator (RSSI) values in conjunction with transmitted power levels to determine the relative location of each device within a small network employing frequency hopped spread spectrum transmission. In addition to the location determination properties of the invention, the geometry of the devices in the network, as well as the path loss information between pairs of devices, may be used to infer the location of absorbers and reflectors within the piconet. This absorption and reflection information may be used in creating the piconet tomography. The approach described in this specification may be applied in conjunction with the Bluetooth wireless Personal Area Network (PAN) specification to determine device locations, mitigate the effects of multi-path, and perform indoor location and security functions, and other application functions requiring cost-effective location determination.

摘要： An optically based location system and method of determining a location at a structure include a lighting infrastructure having lights at a structure. Each light is configured to illuminate and to transmit a respective relative or absolute terrestrial position through modulation of emitted light. An optical receiver is configured to detect the lights, to demodulate the position of detected lights, and to determine from the detection a position of the receiver. The receiver can have a conventional optical detector for determining a two-dimensional position of the receiver relative to a detected light, or can have a three-dimensional spot collimating lens and charged couple device optical detector for determining a three-dimensional position of the receiver relative to a detected light. The receiver and lights can be synchronized for converting a delay time into a distance measurement to calculate a distance between a light and the receiver.

摘要： A device for detecting the direction of a light source. The device has a pin-hole lens that allows a collimated light beam to excite a light sensing surface behind the lens. The output from the light sensing surface is passed to a processor that determines the position of the surface that has been excited and the direction of the light source. When the position of one or more light sources is known, the device may further determine its own position. The devices may be used in a location system to provide known reference points to a network of other devices. The light sources may be modulated, in which the device can select or identify a particular light source based upon its modulation pattern.
