| 20090256699 | SYSTEM AND METHOD FOR CALIBRATION OF RADIO FREQUENCY LOCATION SENSORS - A method includes receiving, in a scanner, at least one radio-frequency (RF) signal from a sensor proximate to the scanner. The method also includes storing location information, corresponding to a location of the scanner, and signal strength information corresponding to the scanner. The method further includes calibrating location records according to the signal strength information and location information. There is also a system for calibrating location records. The system includes a plurality of sensors each configured to transmit an RF signal. The system also includes a scanner configured to receive at least one RF signal from a sensor proximate to the scanner, store location information corresponding to a location of the scanner, and store signal strength information corresponding to the scanner. The system further includes a location manager configured to receive the stored signal strength information and location information from the scanner and to calibrate location records according to the stored signal strength information and location information. | 10-15-2009 |
| 20100014599 | APPARATUS AND METHOD FOR MODIFYING TRANSMISSIONS ON SPECIFIED WIRELESS CHANNELS TO REDUCE INTERFERENCE WITH HIGHER-PRIORITY TRANSMITTERS - A method includes obtaining data to be transmitted wirelessly and detecting if any transmitting devices having a higher priority are currently using at least one of multiple wireless channels. The method also includes transmitting the data wirelessly over the multiple wireless channels in a first specified manner when no transmitting devices having the higher priority are detected. The method further includes transmitting at least a portion of the data wirelessly over the multiple wireless channels in a second specified manner when at least one transmitting device having the higher priority is detected. The data could normally be transmitted using OFDM. When a higher-priority transmitting device is detected, at least a portion of the data could be transmitted using a reduced transmit power and a reduced constellation size and/or larger error correcting code. One or more wireless channels associated with one of two quadrature components could also be suppressed. | 01-21-2010 |
| 20100039280 | METHOD AND APPARATUS FOR WIRELESS ASSET TRACKING USING ASSET TAGS WITH MOTION SENSORS - A system includes an asset tag associated with an asset, the asset tag having a motion sensor to detect a movement of the asset. The system also includes a plurality of readers, each reader receiving one or more signals from the asset tag and measuring a distance between the asset tag and the reader based on the signals. The system further includes a controller receiving a measured distance from each of the plurality of readers and determining a location of the asset based on the measured distances. | 02-18-2010 |

| 20100272090 | APPARATUS AND METHOD FOR INTERFEROMETRIC FREQUENCY MODULATION TO EXPLOIT COOPERATIVE INTERFERENCE IN WIRELESS COMMUNICATIONS - A method includes receiving a first wireless signal and demodulating data in the first wireless signal using a first demodulation technique. The method also includes receiving multiple second wireless signals simultaneously (where the second wireless signals interfere to produce an interfered signal) and demodulating data in the interfered signal using a second demodulation technique. The method could also include (i) determining that a single transmitter transmitted the first wireless signal and selecting the first demodulation technique in response and (ii) determining that multiple transmitters transmitted the second wireless signals and selecting the second demodulation technique in response. Determining that the single transmitter transmitted the first wireless signal could include determining that a fundamental frequency of the first wireless signal is below a threshold. Determining that the multiple transmitters transmitted the second wireless signals could include determining that a fundamental frequency of the interfered signal is above the threshold. | 10-28-2010 |

| 20090165239 | Handheld Vacuum Cleaner - A handheld vacuum cleaner having a housing with an electric motor, a fan driven by the motor, a debris emptying hole for removal of debris from a debris collecting compartment inside the vacuum cleaner, a lid pivotally hinged about a pivot axis and adapted to allow closing and opening of the debris emptying hole, a nozzle defining a nozzle opening in a forward end of the vacuum cleaner through which an air stream may be drawn for collecting debris, and at least two wheels, which are positioned adjacent the nozzle opening and are rotatable about a common rotation axis. The pivot axis for the lid and the rotation axis for the wheels are located on a common axis. | 07-02-2009 |
| 20100088841 | Handheld Vacuum Cleaner - A handheld vacuum cleaner housing with a frame element forming at least a portion of a handle and extending in a main handle direction. A through hole passes through and is encircled by the frame element, and is configured to receive one or more fingers of an operator. A top casing element is connected to the frame element and covers at least some of a top side of the frame element. A bottom casing element is connected to the frame element and covers at least some of the bottom side of the frame element. The frame element, top casing element and bottom casing element are arranged to form at least part of a vacuum source housing for accommodating at least a part of a vacuum source. A vacuum cleaner having a similar housing, as well as a detachable second housing having a debris compartment and nozzle, is also provided. | 04-15-2010 |
