Abstract: An information management system and the like capable of managing communication processing by an internal system mounted on a mobile apparatus such as a motor vehicle to ensure efficient use of information processing resources for packets distributed from an external system are provided. According to the information management system (100), a first processing section (110) determines necessity/unnecessity of a file for an information processing device (12) mounted on the motor vehicle based on file information about the content of the file distributed or transmitted from an external system (20). If the first processing section (110) determines that the file is necessary for the information processing device (12), a second processing section (120) causes the internal system (10) to execute “relay processing” of the file including collection and accumulation of packets, decoding of the packets to restore the file, and others.

Abstract: A method for installing EXT (extended) file system from a server to at least a client, the method includes the following steps. The super blocks of original files in a server are read to obtain subarea basic parameters of original files which are then packed into an image file. The reserved nodes and the first data pointing to the reserved nodes are analyzed in sequence. Whether the reserved nodes point to directory files is judged. A directory sequence is created according to the judge result. The nodes and the first data pointing to the nodes is reviewed. A client receives the image file and separates the subarea basic parameters of original files and data blocks from the image file, and calculates the basic data and data blocks for storing them in the client.

Abstract: Two regularized estimators that avoid the pathologies associated with variance estimation are disclosed. The regularized variance estimator adds a contribution to estimated variance representing the likely error, and hence ameliorates the pathologies of estimating small variances while at the same time allowing more reliable estimates to be balanced in the convex combination estimator. The bounded variance estimator employs an upper bound to the variance which avoids estimation pathologies when sampling probabilities are very small.

Abstract: Configuration information is exchanged between a home entertainment system server and various wireless components by pushing a button on the server and a random button on a remote control device as it is pointed at the devices sought to be authenticated.

Abstract: In processing a priority queue, the elements are kept in an unsorted stack and are searched for the next highest priority element only after the highest priority element has been read from the holding register. Each time a new element is written into the queue, a comparison is made of the priority of the new element with the priority of the existing element in the holding register. If the new element has a higher priority, then the existing element in the holding register is written onto the top of the stack. Alternately, if the element in the holding register has the higher priority, then the new element is written onto the top of the stack. This assures that the holding register always contains the element having the highest priority. Therefore, a read of the priority queue by reading the contents of the holding register guarantees that the highest priority element is there and it can be accessed immediately without further searching the queue.
