摘要： A recursive lambda rule engine (114, 302) includes a first multiplier (204) that sequentially multiplies each of series of inputs by a nonlinearity determining parameter and supplies results to a second multiplier (214) that multiplies the output of the first multiplier (204) by a previous output of the engine (114, 302). A three input adder (220, 228) sequentially sums the output of the second multiplier (214), inputs from the series of inputs, and the previous output of the engine (114, 302). A shift register (244) is used to feedback the output of the engine (114, 302) to the three input adder (220, 228) and second multiplier (214). A MUX (234) is used to route an initial value through the shift register (244) for the first cycle of operation.

摘要： An nonlinear digital signal processing filter (100, 200, 1100, 1308, 1310, 1312, 1346, 1604) maintains a magnitude ordering for successive windows of signal samples. A set of filter density generator values [f1, f2, f3 . . . fj . . . fndensities] are used according to the ordering in a recursion relation that computes successive values of a set function over the set of filter density generator values. The recursion relation involves an adjustable nonlinearity defining parameter λ. The values are normalized by dividing by a largest of the values, and differences between successive values are taken. An inner product between each window of signal values (used in order according to magnitude) and the adaptive differences is a filtered signal sample.

摘要： A charger docking station (102) is used to charge a battery (122) of a portable information device (104), and provide enhanced input (110) and enhanced output (112) ability. The enhanced input allows a user to more easily input information into the portable information device, while the enhanced output allows the user to view more information than may be displayed by a display (126) of the portable information device. When the charger docking station is connected to a power source (116) a power supply (114) provides power to the enhanced input and display elements, but when the power source is disconnected from the power supply, the enhanced input and display elements are powered from the battery of the portable information device, or from an external auxiliary battery (106), or both.

摘要： A method and apparatus for determining a range within a wireless communication system is provided herein. The range information can then be used to locate a node (e.g., an asset tag). During operation, the minimum transmission power of a source transceiver (e.g., an RFID reader) that enables a tag to be detected will be used to indicate distance. Changes in transmit power will be used to indicate relative changes in distance to a particular node. The reader will be configured to always operate at a transmission power that will result in a certain percentage (e.g., 50%) detection rate for a target transceiver (e.g., an RFID asset tag). As the reader moves closer to the tag, the minimum detection power will decrease; as it moves farther from the tag, the minimum detection power will increase. This information is displayed to give a general change in range information between the RFID reader and the asset tag (e.g., increasing range or decreasing range). An individual will be able to easily locate the asset tag by using the displayed information.

摘要： Disclosed is a system for updating an RSSI-based map. A scanning devices notes which tags are seen during a scan and measures a “proxy distance” from the scanning device to each tag. When the scan is initiated, the scanning device measures the RSSIs from the local WAPs. The current location of the scanning device is determined by triangulating from the proxy distances of the scanned tags. That location is then correlated with the contemporaneously measured RSSIs. The correlation is used to update the RSSI-based map. In some embodiments, it is not the scanning device that measures the RSSIs. Instead, the WAPs measure the RSSIs from the scanning device whenever the scanning device transmits the results of a scan. In some embodiments, the operator of the mapped environment places scannable tags at fixed locations. Scans of these fixed-location tags are especially useful when determining the current location of the scanning device.
摘要翻译：公开了一种用于更新基于RSSI的地图的系统。扫描设备注意到扫描期间看到哪些标签，并测量从扫描设备到每个标签的“代理距离”。当扫描开始时，扫描设备测量来自本地WAP的RSSI。扫描装置的当前位置通过从扫描标签的代理距离三角测量来确定。然后该位置与同时测量的RSSI相关。相关性用于更新基于RSSI的地图。在一些实施例中，不是测量RSSI的扫描设备。相反，每当扫描设备发送扫描结果时，WAP就会从扫描设备测量RSSI。在一些实施例中，映射环境的操作者将可扫描标签放置在固定位置。当确定扫描设备的当前位置时，这些固定位置标签的扫描特别有用。
