Abstract: When conference conditions are set by a conference sponsor, a conference sponsor agent inquires of schedule management agents of requested attendants about available time within a range of set dates, determines an optimum conference schedule on the basis of the available time of the individual requested attendants, sends to the conference sponsor the conference schedule for confirmation thereof, and sends a conference notification to the requested attendants. In order to permit an input value set by a user to have a range in accordance with the kind of parameter requiring the input value and conditions at that time, an input value acquiring element acquires an input value of a parameter necessary for a processing realized by an application element, the input value being set by the user by an input element.

Abstract: A power consumption control apparatus for an information processing apparatus having multi-tasking control which executes a plurality of information processing operations in parallel by time-divisionally switching a plurality of tasks in an arithmetic processing unit. The power consumption controlled apparatus detects an event where there are no information processing operations to be executed, sets the arithmetic processing unit to a power-saving mode in response to the event and immediately clears the power-saving mode set in the arithmetic processing unit in response to an interrupt signal from an input/output device. Alternatively, the power consumption control apparatus after detecting the event stops supply of a clock to the arithmetic processing unit or lowers a frequency of the clock in response to the event.

Abstract: A system for processing information with an electronic pen includes a coordinates indicating device and a coordinates sensing device. Both of the devices serves to output the information stored in itself to each other and store the information outputted from the other. The power supply for driving the information processing system itself is fed by a battery built in the coordinates indicating device.

Abstract: A system which comprises a message data base for storing help messages, a history buffer for storing the past statuses of an interactive processing system, an inference engine for determining a help message to be outputted, and a rule data base for storing the rules for determining a help message by said inference engine, determines an output help message on the basis of at least the past status history using said inference engine, furthermore outputs a help message by a user's command, selects a message data base to be used by the system at that time from a plurality of message data bases, or selects a rule data base to be used by the system at that time from a plurality of said rule data bases

Abstract: A method of help-information control for displaying help information on a display unit of an information processing system executing a plurality of application programs. A status management table for storing the executing status of application programs is provided as common to these programs. During execution of a given application program, the contents of the status information table are updated successively in accordance with the executing status. Whenever an operator makes a help request, the contents of the status management table in effect at that point in time are referenced. The table is searched for the help information corresponding to the request. When found and retrieved, the information is displayed. The search is performed using a program identifier, a message identifier, and a help message searching table that includes the position information containing the corresponding help data.

Abstract: Control is performed for each of the individual components in accordance with a table including information on clock control and power control of each component of an information processing apparatus. Clock supply is stopped or clock frequency is lowered immediately or after the lapse of a predetermined period of time since the component is brought into an unused condition. Supply of power is stopped immediately or after the lapse of a predetermined period of time. In this case, the predetermined period of time can be automatically adjusted by detecting the condition of access to the component.
