Abstract: A user can link a station to an access point by triggering buttons of the station and the access point respectively. After the buttons are triggered, the station scans the SSID of the access point. The access point updates SSID and sends out the new SSID to the station in response to the station's request. Then, the station generates a security key according to the new SSID and links the access point according to the new SSID and the security key so as to establish a WLAN link.

Abstract: Techniques are described for assigning, to target categories of a target scheme, items that have been obtained from a plurality of sources. In situations in which one or more of the sources has organized its information according to a source scheme that differs from the target scheme, the assignment may be based, in part, on an estimate of the probability that items from a particular source category should be assigned to a particular target category. Such probability estimates may be based on how many training set items associated with the particular source category have been assigned to the particular target category. Source categories may be grouped into clusters. The probability estimates may also be based on how many training set items within the cluster to which the particular source category has been mapped, have been assigned the particular target category.

Abstract: Disclosed is a codec (coder/decoder) system with shadow buffers and method of performing a Power Down/Suspend mode operation on this codec system, which allows all the codecs in the codec system to know the operating status of each other so that system crash can be prevented during a power down/suspend operation. The codec system includes two or more codecs and associated codec controllers, with each codec controller including a status data buffer and a shadow buffer; and each codec controller utilizes the status data buffer therein for registering the operating status thereof and meanwhile utilizes the shadow buffer therein for storing a copy of the operating status data stored in the status data buffer of the other codec controller. The provision of the shallow buffers allows all the codecs in the codec system to be capable of knowing the operating status of each other. This feature can help prevent system crash during power down/suspend operation.
