Abstract: In a mobile communication network, a mobile terminal is set in one of a number of user-defined response modes. The information indicating the set response mode is stored in a status memory, and the stored information is transmitted to the calling user of an incoming call addressed to the mobile terminal from the network. The status memory is preferably located in the network to respond to the incoming call by the network, or may be located in the mobile terminal to respond to the incoming call by the mobile terminal. Preferably, verification is provided for the calling user prior to responding to the incoming call. A field strength or signal-to-noise ratio detector may be provided to communicate the field strength or SNR value of the channel established by the mobile terminal. The calling user is informed of such channel quality information to determine the best communication mode.

Abstract: A device for recording and retrieving images corresponding to a plurality of documents is based on an apparatus which generates images which respectively correspond to a plurality of original documents, rotates those images to provide a more meaningful image for the user, and records those images on a recording medium. The image corresponding to each document which is scanned subsequent to the first document is rotated based on whether the image corresponding to the first document is rotated or not. A comparison between a pixel count on the image corresponding to the first document may be compared with a pixel count corresponding to each subsequently generated image to determine whether such rotation should be performed. Original documents are scanned in the sub-scanning direction and rotated after scanning to increase scanning speed. Retrieval data for each image is stored for retrieval purposes.
