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 |

20150036458 | MIXER HOUSEHOLD APPLIANCE - A mixer household appliance having a container unit and a base unit. The container unit includes a container for foodstuff and a rotor element arranged inside the container at a first end of the container unit. The appliance further includes a lid for at least partially covering an opening of the container unit. A device extends into the container via the lid and includes a surface element. The device is arranged to be fixedly positioned in at least a first position and a second position. In the first position of the device, the surface element is arranged at a first distance from the rotor element. In the second position of the device the surface element is arranged at a second distance from the rotor element. | 02-05-2015 |
20150036459 | MIXER HOUSEHOLD APPLIANCE - A mixer appliance having a base unit and a container unit. The base unit has a motor with a drive shaft. The container unit has a container and a rotor with a rotor shaft and a rotor element. A coupling arrangement connects the drive shaft and the rotor shaft when the container unit is connected to the base unit. A longitudinal axis extends through the drive shaft, coupling arrangement, and rotor shaft. The container unit has a bottom portion with a flexible diaphragm and a bearing member. The bearing member is supported by the flexible diaphragm, and the rotor shaft extends through the bearing member. The flexible diaphragm provides flexibility perpendicularly to the longitudinal axis, such that the bearing member is displaceable perpendicularly to the longitudinal axis to align the rotor shaft with the drive shaft along the longitudinal axis when the container unit is connected to the base unit. | 02-05-2015 |
20150082839 | APPLIANCE FOR TREATING A TEXTILE AND METHOD FOR TREATING A TEXTILE - An appliance for treating a textile. The appliance has a textile contact surface adapted to interact with the textile to be treated, an airflow generating device, and a first outlet connected to the airflow generating device. The first outlet is arranged adjacent to the textile contact surface. The first outlet is arranged to direct an airflow through the first outlet in an airflow direction that is directed away from a normal of the textile contact surface. | 03-26-2015 |
