`ABSTRACT
`
`
`
`
`
`
`
`
`
`
`An information processor capable of recognizing whether
`
`
`
`
`
`
`the possessor(user) of the information processoris carrying
`
`
`
`
`
`
`
`
`the information processor or located in the vicinity of the
`
`
`
`
`
`
`information processor. The information processor performs
`
`
`
`
`
`
`
`a suitable processing operation according to the possessor’s
`
`
`
`
`
`
`(user’s) carrying or non-carrying condition. The information
`
`
`
`
`
`
`
`processor has a transmitting section to transmit a signal
`
`
`
`
`
`
`receivable only in the range of a predetermined distance to
`
`
`
`
`
`
`a wristwatch type
`information processor previously
`
`
`
`
`
`
`
`
`assigned, a receiving section to receive a signal sent from the
`
`
`
`
`
`
`wristwatch type information processor in response to the
`
`
`
`
`
`
`
`signal transmitted by the transmitting section, a decision
`
`
`
`
`
`
`
`
`section to make a determination as to whether the reply
`
`
`
`
`
`
`
`
`signal has been received by the receiving section, and a
`
`
`
`
`
`
`processing operation control section to execute a predeter-
`
`
`
`
`
`
`
`mined processing operation depending upontheresult of the
`
`
`
`
`
`determination made by the decision circuit.

`BACKGROUND OF THE INVENTION
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`[0001]
`1. Field of the Invention
`
`
`
`
`
`
`
`[0002] The present
`invention relates to an information
`
`
`
`
`
`processor, such as a portable telephone, or a portable digital
`
`
`
`
`assistant, having a communication function, an information
`
`
`
`
`processing method, and a computer-readable recording
`
`
`
`
`
`medium on which a program for making a computer perform
`
`
`
`
`
`
`a process based on the method is recorded.
`
`
`
`
`
`
`[0003]
`2. Description of the Related Art
`
`
`
`
`
`
`[0004] Portable information processors, such as portable
`
`
`
`
`
`
`telephones and mobile computers, having a communication
`
`
`
`
`
`
`
`
`
`function, have recently come into wide use. A person who
`
`
`
`
`
`
`
`operates such a portable information processor can easily
`
`
`
`
`
`
`
`carry the information processor and perform communication
`
`
`
`
`
`
`
`anywhere by using the information processor. It is presup-
`
`
`
`
`
`
`
`
`
`posed that
`the possessor (user) of such an information
`
`
`
`
`
`
`
`processor always carries the information processor. How-
`
`
`
`
`
`
`
`
`ever, the possibility of the possessor losing or mislaying the
`
`
`
`
`
`
`
`information processor and the possibility of the information
`
`
`
`
`
`
`
`
`processorbeing stolen are not negligible. Therefore, there is
`
`
`
`
`
`
`
`
`a possibility of the information processor not being carried
`
`
`
`
`by the possessor(user).
`
`
`
`
`
`
`
`
`[0005] When the possessor (user) is not carrying the
`
`
`
`
`
`
`
`information processor, the information processor maybeleft
`
`
`
`
`
`
`
`
`
`in such a state that an unauthorized person can operate the
`
`
`
`
`
`
`information processor without possessor’s (user’s) permis-
`
`
`
`
`
`
`
`
`
`sion to perform communication and can steal or change
`
`
`
`
`
`
`
`information stored in the information processor (e.g., a
`
`
`
`
`
`telephone numberlist in a portable telephone).
`
`
`
`
`
`
`
`[0006] Also, if the information processor receives a signal
`
`
`
`
`
`
`
`from an external device when the possessor (user) is not
`
`
`
`
`
`
`
`
`carrying the information processor, alert means (e.g., an
`
`
`
`
`
`
`
`incoming call sound means for a portable telephone)
`
`
`
`
`
`
`
`intended to inform the possessor (user) of arrival of such a
`
`
`
`
`
`
`
`signal operates continuously to annoy people in a place
`
`
`
`
`
`
`
`
`where the information processor exists, or to waste power
`
`
`
`
`for the information processor.
`
`
`
`
`
`
`
`[0007] Further, the person who has transmitted the signal
`
`
`
`
`
`
`from the external device (transmitting terminal) cannot
`
`
`
`
`
`
`
`know whether the possessor (user) of the information pro-
`
`
`
`
`
`
`
`cessor is carrying the information processor, so that the
`
`
`
`
`
`communication functions of the information processor can-
`
`
`
`not be effectively performed.
`
`
`
`
`
`
`
`
`
`SUMMARYOF THE INVENTION
`
`
`
`
`
`
`
`
`
`[0008]
`In view of the above-described problems of the
`
`
`
`
`
`
`
`
`
`conventional art, an object of the present invention is to
`
`
`
`
`
`
`
`provide an information processor capable of making a
`
`
`
`
`
`
`
`
`determination as to whether the possessor (user) of the
`
`
`
`
`
`
`information processoris carrying the information processor
`
`
`
`
`
`
`
`
`
`
`(or is in the vicinity of the information processor), and
`
`
`
`
`
`
`
`capable of suitably operating according to the state of being
`
`
`
`
`
`
`carried or not carried by the possessor (user).

`[0009]
`To solve the above-mentioned problem and to
`
`
`
`
`
`
`
`
`achieve the object described above, according to one aspect
`
`
`
`
`
`
`
`of the present invention, there is provided an information
`
`
`
`
`
`processor comprising transmitting means for transmitting a
`
`
`
`

`information processor previously
`to
`
`
`
`
`
`
`
`assigned, receiving means for receiving a reply signal sent
`
`
`
`
`
`
`
`from the other information processor in response to the
`
`
`
`
`
`
`
`signal
`transmitted by the transmitting means, decision
`
`
`
`
`
`
`means for making a determination as to whether the reply
`
`
`
`
`
`
`
`
`
`signal has been received by the receiving means, and pro-
`
`
`
`
`
`
`
`cessing operation control means for executing a predeter-
`
`
`
`
`
`
`
`mined processing operation depending upontheresult of the
`
`
`
`
`
`determination made by the decision means.
`
`
`
`
`
`
`
`[0010] According to the present invention, the predeter-
`
`
`
`
`
`
`mined processing operation is performed if the distance to
`
`
`
`
`
`
`
`
`the other information processoris equal to or larger than the
`
`
`predetermined distance.

`
`
`
`
`
`
`commands to perform operations, wherein the transmitting
`
`
`
`
`
`
`
`
`
`meanstransmits the signal receivable only in the range of the
`
`
`
`
`
`
`predetermined distance to the other information processorif
`
`
`
`
`
`
`
`a predetermined operation command is issued from the
`
`
`
`
`
`
`
`operation command means, and wherein the processing
`
`
`
`
`
`
`operation control means executes a processing operation
`
`
`
`
`
`
`
`corresponding to the operation command issued by the
`
`
`
`
`
`
`
`operation command means depending upontheresult of the
`
`
`
`
`
`determination made by the decision means.
`
`
`
`
`
`
`[0012] According to the present invention, the operation
`commandiseffective if the distance to the other information
`
`
`
`
`

`
`
`
`
`
`
`
`from another information processor in responseto the signal
`
`
`
`
`
`
`
`transmitted by the transmitting means, decision means for
`
`
`
`
`
`
`
`making a determination as to whether the reply signal has
`
`
`
`
`
`
`
`
`
`been received by the second receiving means, and alert
`
`
`
`
`
`
`
`means for performing alerting with respect to the reception
`
`
`
`
`
`
`
`of the signal by the first receiving means depending uponthe
`
`
`
`
`
`result of the determination made by the decision-means.
`
`
`
`
`
`
`[0014] According to the present invention,it is possible to
`
`
`
`
`
`
`
`
`

`processor and the mode of not transmitting.
`
`
`
`
`
`
`[0016] According to the present invention, even if the
`

`
`
`
`
`processor (portable telephone) 100, a second information
`
`
`
`
`
`
`processor (wristwatch type information processor) 101, and
`
`
`
`
`
`
`a repeating station (base station) 102.
`
`
`
`
`
`
`
`(portable tele-
`[0038] The first
`information processor
`
`
`
`
`
`
`
`phone) 100 is an information processor in the form of a
`
`
`
`
`
`
`
`portable telephone, a portable unit of the Personal Handy
`
`
`
`
`
`
`
`Phone System (PHS), a mobile personal computer, a radio
`
`
`
`
`
`
`
`
`pager, or the like capable of performing unidirectional or
`
`
`
`
`
`
`
`bidirectional communication with the repeating station 102.
`
`
`
`
`
`
`
`
`The functions for communication with the repeating station
`
`
`
`
`
`
`
`
`(base station) 102 can be performed based on the conven-
`
`
`
`
`
`
`
`
`tional
`techniques and,
`therefore, will not specially be
`described in detail.
`
`
`
`
`
`
`
`
`
`[0039] The second information processor (wristwatch type
`
`
`
`
`
`
`
`
`information processor) 101 itself does not perform commu-
`
`
`
`
`
`
`
`
`
`
`nication with the repeating station (base station) 102, but can
`
`
`
`
`
`
`perform short-distance wireless communication with the
`
`
`
`
`
`
`
`first information processor (portable telephone) 100. The
`
`
`
`
`
`
`second information processor 101 is a wristwatch type
`
`
`
`
`
`
`information processor in this embodiment. The possessor of
`
`
`
`
`
`
`
`
`
`the first and second information processors 100 and 101
`
`
`
`
`
`
`
`ordinarily wears the second information processor 101 on a
`
`
`
`
`
`
`
`
`wrist, enabling the first information processor 100 to rec-
`
`
`
`
`
`
`
`
`ognize whether the distance between the possessor (user)
`
`
`
`
`
`
`
`
`and the first information processor 100 is short enough to
`
`
`
`
`perform short-distance wireless communication.
`
`
`
`
`
`
`
`
`[0040] The second information processor 101 is not lim-
`
`
`
`
`
`
`
`
`ited to the wristwatch type information processor, and may
`
`
`
`
`
`
`
`
`be of any other type as long as it can always be carried by
`
`
`
`
`
`
`
`the possessor (user). For example, it may be of a pendant
`
`
`
`
`
`
`
`type such as to be suspended from the possessor’s neck, or
`
`
`
`
`
`
`
`of such a type as to be attached to a jacket or the like.
`
`
`
`
`
`
`
`
`[0041] A portable telephone is ordinarily carried by the
`
`
`
`
`
`
`
`
`possessor (user). However, the possessor (user) may lose or
`
`
`
`
`
`
`
`mislay the portable telephone in a particular place (e.g.,
`
`
`
`
`
`
`
`possessor’s homeor an office) or the portable telephone may
`
`
`
`
`
`
`
`
`
`
`be stolen. In such a case,
`it is probable that the distance
`
`
`
`
`
`
`
`
`between the point at which the portable telephone is located
`
`
`
`
`
`
`
`
`and the point at which the possessor (user) is located is
`
`
`
`
`
`
`
`
`longer than the maximum distance over which short-dis-
`
`
`
`
`
`tance wireless communication can be performed.
`
`
`
`
`
`
`
`[0042] Also, in a case where a person works by operating
`
`
`
`
`
`
`
`a particular type of information processor (e.g., a personal
`
`
`
`
`
`
`
`
`
`computer) on a desk, the operator may leave from the desk
`
`
`
`
`
`
`
`
`
`for some purpose, and the distance between the point at
`
`
`
`
`
`
`
`
`which the portable telephone is located and the point at
`
`
`
`
`
`
`
`
`
`which the possessor (user) may become longer than the
`maximum distance over which short-distance wireless com-
`
`
`
`
`
`
`
`
`
`
`munication can be performed.
`
`
`
`
`
`communication
`[0043] For
`short-distance wireless
`
`
`
`
`
`
`
`between the first information processor (portable telephone)
`
`
`
`
`
`
`
`
`100 and the second information processor (wristwatch type
`
`
`
`
`
`
`information processor) 101, a short-distance wireless com-
`
`
`
`
`
`
`
`munication,e.g., “Bluetooth” may be used. “Bluetooth” uses
`
`
`
`
`
`
`
`a frequency bandwidth of 2.45 GHz, a connection distance
`
`
`
`
`
`
`
`coverage of about 10 m, and a transfer rate of about 1 Mbps.
`
`
`
`
`
`
`
`Therefore,
`if a port
`in accordance with “Bluetooth” is
`
`
`
`
`
`
`
`provided, various devices, such as portable telephones,
`
`
`
`
`
`
`
`portable personal computers and peripheral devices, can be
`connected.

`
`(Configuration of Information Processor)
`[0044]
`
`
`
`
`
`
`[0045] The hardware configuration of the first information
`
`
`
`
`
`
`
`
`processor (portable telephone) 100 and the second informa-
`
`
`
`
`
`
`
`tion processor (wristwatch type information processor) 101
`
`
`
`
`
`
`
`will next be described with reference to FIG. 2, which is a
`
`
`
`
`
`
`
`block diagram showing an example of the hardware con-
`
`
`
`
`
`
`
`
`figuration of the first and second information processors
`
`
`
`
`
`
`
`(portable telephone and wristwatch type information pro-
`
`
`
`
`cessor) according to this embodiment.
`
`
`
`
`
`
`
`
`[0046] Referring to the block diagram of FIG.2, the first
`
`
`
`
`
`
`information processor (portable telephone) 100 is consti-
`
`
`
`
`
`
`
`tuted by a control section 200, a transmitting and receiving
`
`
`
`
`
`
`
`
`section 201, a data conversion section 202, a speech pro-
`
`
`
`
`
`
`
`cessing section 203, a speaker 204, a microphone 205, a
`
`
`
`
`
`
`
`
`switch section 206, a display section 207, a memory section
`
`
`
`
`
`
`
`
`208, and a wireless transmitting and receiving section 209.
`
`
`
`
`
`
`
`
`[0047] The control section 200 is constituted by, for
`
`
`
`
`
`
`
`example, a central processing unit (CPU), and performs
`
`
`
`
`
`
`
`overall control of the processor. The transmitting and receiv-
`
`
`
`
`
`
`ing section 201 is constituted by a communication unit, a
`
`
`
`
`
`
`
`
`modem,etc., and performs communication with the repeat-
`
`
`
`
`
`
`
`
`
`ing station (base station) 102. The data conversion section
`
`
`
`
`
`
`
`202 converts data received by the transmitting and receiving
`
`
`
`
`
`
`
`
`section 201 into data processible by speech processing in the
`
`
`
`
`
`
`
`speech processing section 203 and, conversely, converts data
`
`
`
`
`
`
`
`speech-processed by the speech processing section 203 into
`
`
`
`
`
`
`
`data transmittable by the transmitting and receiving section
`201.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`[0048] The speech processing section 203 converts data
`
`
`
`
`
`
`
`
`
`supplied from the data conversion section 202 into speech
`
`
`
`
`
`
`
`
`
`data which can be output through the speaker 204. Con-
`
`
`
`
`
`
`
`
`versely, the speech processing section 203 converts a speech
`
`
`
`
`
`
`
`
`input from the microphone 205 into data to be supplied to
`
`
`
`
`
`
`
`
`
`the data conversion section 202. The speaker 204 is operated
`
`
`
`
`
`
`
`
`to output speech, and the microphone 205 is operated to
`
`
`input speech.
`
`
`
`
`
`
`
`[0049] The switch section 206 is provided to operate the
`
`
`
`
`
`
`information processor in various ways. For example, the
`
`
`
`
`
`
`switch section 206 comprises a keyboard or a touch panel.
`
`
`
`
`
`
`If the information processor is a portable telephone, the
`
`
`
`
`
`
`switch section 206 comprises a ten-Key cluster, a power
`
`
`
`
`
`
`
`
`switch, etc. The display section 207 is a thin film transistor
`
`
`
`
`
`
`
`
`(TFT) liquid crystal display or the like. The display section
`
`
`
`
`
`
`207 displays details of an operation, operation results, etc.
`
`
`

`
`Theslave unit control section 210 is constituted by,
`[0052]
`
`
`
`
`
`
`
`for example, a microprocessor forming a CPU,and performs
`
`
`
`
`
`
`
`
`
`overall control of the slave unit. The slave unit transmitting
`
`
`
`
`
`
`
`
`and receiving section 211 performs communication with the
`
`
`
`
`
`
`
`
`information processor 100. The slave unit display section
`
`
`
`
`
`
`
`
`212 is constituted by a display screen in the face of a
`
`
`
`
`
`
`
`
`wristwatch. The slave unit display section 212 displays, as
`
`
`
`
`
`
`
`well as time, conditions of communication with the infor-
`
`
`
`
`
`
`
`mation processor 100, details of an operation, operation
`
`
`results, etc.
`
`
`
`
`
`
`
`
`
`[0053] The slave unit switch section 213, not shown in
`
`
`
