  • Patent number: 5754629
    Abstract: A schedule management system which can display a schedule on a screen and enables the user to enter schedule topics promptly and accurately without performing complicated operation is provided. An external voice is input through a microphone or a network control unit and is converted into a digital signal by an A/D converter and a coder. An identifier related to the digital signal is generated. The identifier is displayed on a schedule on a display unit. The digital signal is stored in a memory in relation to the identifier. A user specifies the displayed identifier through an operation section, whereby the digital signal related to the identifier is extracted from the memory by a CPU, the extracted digital signal is converted into an analog signal by a D/A converter, and the analog signal is output as a voice through a loudspeaker or the network control unit to the outside. Like a voice, an image can also be handled.

  • Patent number: 5432899
    Abstract: A method for managing resources and an information processing system having three or more information processing units, with one unit functioning as a server and the other two or more units functioning as clients. A client unit can send a first resource, such as a document file, to the server unit for processing, such as printing the first resource. A second resource, such as character fonts, is generally required for processing the first resource if the server does not hold the second resource information. Together with the first resource, the client unit sends address information about the location of the second resource to the server unit. If the private character code is included in the character string, the server reads the private character font corresponding to the client which created the document file. Unfavorable change of a private character sent from a client to the server each time a new client is added to the system is avoided. Consequently, the document file may be processed, e.g.
