  • Publication number: 20190394361
    Abstract: A camera captures and records a moving image. The camera transmits, to a server, still images extracted at first time intervals from the moving image. The server transmits the still images to an administrator terminal. The administrator terminal accepts input for designating the still image. The server transmits an information item for specifying the designated still image to the camera. The camera transmits, to the server, the moving image having a predetermined duration preceding and including the designated still image, or a plurality of the still images extracted at second time intervals each shorter than the predetermined duration from the moving image having the predetermined duration. The server transmits, to the administrator terminal, the moving image having the predetermined duration, or the plurality of the still images extracted at the second time intervals.

  • Patent number: 7764480
    Abstract: A mobile terminal uses a battery as a power source, and has a battery protection circuit for protecting the battery. A control circuit of the mobile terminal detects a voltage value or a current value of a predetermined electronic circuit such as a power amplifier, and determines whether or not an abnormal state is present. Upon determination that the power amplifier is in an abnormal state, the control circuit short-circuits the battery to operate the battery protection circuit. As a result, the supplying of a power supply current to the power amplifier is stopped to eliminate the abnormal state.

  • Publication number: 20040102211
    Abstract: A mobile terminal, which is a foldable type mobile communication terminal, in which the posture of the mobile terminal is detected by a simple structure that adds some components to an existing opening and closing structure for the upper cabinet of the foldable type mobile communication terminal, is provided. The mobile terminal provides a magnet in the upper cabinet, two magnetic sensors in the lower cabinet, and a controlling means. The magnet moves corresponding to the change of the posture of the mobile terminal. The two magnetic sensors detect the magnetic force from the magnet. The controlling means judges the posture of the mobile terminal based on the detected magnetic force. The magnet and the two magnetic sensors are also used for detecting the opening or closing state of the upper cabinet.

  • Publication number: 20030044022
    Abstract: The present invention provides a mobile terminal equipment having local circuits susceptible to the influence of magnetic field fluctuation, which is capable of reducing phase shift of the local circuit arrangement even when a magnetic field fluctuation occurs. In the mobile terminal equipment, when the speaker is activated to emit a sound at a specific fixed frequency, a phase shift which is generated in the PLLIC due to the influence of an electromotive force produced in the VCO accompanying with a magnetic field fluctuation caused by fine vibration of the speaker magnet section, is reduced by performing fine adjustment of the frequency of the VCTCXO, thus the deterioration of modulation accuracy characteristics during the sound emission of the speaker is restrained.

  • Patent number: 6356770
    Abstract: A composite mobile communication device allowing the reduced amount of hardware and a high-speed data communication is disclosed. One communication circuit uses a local oscillation signal of the other communication circuit to allow a one-frame-two-slot assignment communication on time-division duplex scheme when the other communication circuit does not operate. Since the local oscillation signal of the other communication circuit is used, there is no need of a local circuit to perform the one-frame-two-slot assignment communication.

  • Patent number: 6195570
    Abstract: When a power source is turned on, a menu screen is displayed on LCD. When the insertion of an earphone jack is detected with the menu screen displayed, display on LCD is automatically switched from the menu screen to a dialing screen. A user can have conversation with a desired party by dialing using the displayed dialing screen. If the insertion of an earphone jack is detected while another processing is executed using the menu screen after the power source is turned on, the processing is temporarily interrupted and the dialing screen is displayed on LCD. The temporarily interrupted processing is executed again when a call is finished. Even during a call, another processing can be executed using the menu screen.

  • Patent number: 6115582
    Abstract: A radio selective calling receiver for bringing into possible to implement leading-in synchronization rapidly by performing rapid-scan by virtue of switch manipulation as a trigger in the receiver out of the service area. When receiving section exists out of the service area, the receiver implements auto-scan of reception frequency with definite cycle interval, while when the receiver enters the service area, the receiver implements leading-in synchronization automatically. The control section causes cycle of the auto-scan to change by switch manipulation out of the service area.

  • Patent number: 6049696
    Abstract: In a radio selective calling receiver, a control section 103 has a DTMF signal generating section 103F that converts a transmit message into a dial tone signal to output the dial tone signal. A CPU section 103B of the control section 103 can transmit a message from the DTMF signal generating section 103F in the state that a message received from another receiver is read from a RAM section 103C and displayed on a display section 10, and at this time stores the receive message and the transmit message in association with each other in the RAM section 103C. When reading the receive message, the transmit message corresponding to the receive message is also displayed on the display section 107.
