  • Publication number: 20150160710
    Abstract: An information processing terminal according to the present invention includes: a state controlling means for controlling switching of a state of the information processing terminal between a first power setting state and a second power setting state which is a more power save setting than the first power setting state; an input operation accepting part configured to accept a predetermined input operation; and an operation object detecting part configured to detect an operation by a preset operation object. The state controlling means is configured to switch the state from the second power setting state to the first power setting state when, in the second power setting state, the input operation is accepted by the input operation accepting part and also an operation by the operation object is detected by the operation object detecting part.

  • Publication number: 20150130728
    Abstract: An information processing device according to the present invention includes: a display input part accepting an operation of an operation object; an operation detecting means for accepting an input operation of the operation object by detecting an operation position of the operation object on a face of the display input part; and a controlling means for executing a preset process in accordance with the input operation. Based on the accepted input operation, the operation detecting means detects either a first operation state or a second operation state in the same operation position on the face of the display input part. The controlling means gives an instruction for designation of specified information selected by the input operation, when the operation detecting means detects the first operation state, and gives an instruction for confirmation of the specified information, when the operation detecting means detects the second operation state.

  • Patent number: 7541779
    Abstract: A portable electronic device and a mobile communication terminal, whose surface temperature does not increase while being charged regardless of the type of a charger for charging a storage battery being mounted therein. When a cell-phone unit, which has a radio section being a heat source and operates with a battery pack mounted therein as a power source, is connected to an external power feeder with the battery pack being mounted, the battery pack is charged by current from the external power feeder. When the battery pack is charged while the radio section is operating, the value of the charging current to charge the battery pack is reduced less than that when the radio section is not operating.

  • Patent number: 7428016
    Abstract: A portable electronic device with a camera of the present invention comprises a camera portion, a first light source outputting a first light as a strobe light emitting operation in connection with a photographing operation of the camera portion, a second light source outputting a second light for display and an illumination lens through which the first light and the second light exit the device. The illumination lens outputs both of the first light and the second light. A light diffuser, such as a prism reflects the second light to the illumination lens side between the illumination lens and the first light source, the second light reaching the first light source having been made as small as negligible.

  • Publication number: 20040207749
    Abstract: A portable electronic device with a camera of the present invention comprises a camera portion, a first light source such as a white LED or the like for outputting a first light as a strobe light emitting operation in connection with a photographing operation of the camera portion, a second light source such as a blue LED or the like for outputting a second light for display and an illumination lens through which the first light and the second light exit to the outside; the illumination lens serving for outputting both of the first light and the second light. By providing a light diffusing means such as a prism sheet or the like for reflecting the second light emitted from the second light source to the illumination lens side between said illumination lens and the first light source, the second light reaching the first light source has been made as small as negligible.

  • Patent number: 6411829
    Abstract: Radio communication equipment is provided which is capable of reliably completing a charge of a battery at a proper charging capacity and without causing deterioration of the battery regardless of whether or not a backlight function is continuously used at the time of charging. When a portable telephone starts charging, a CPU judges whether the backlight is turned ON. If the backlight is turned ON, a signal indicating that it is in the ON state is outputted from the CPU to a charging completion detecting circuit. The charging completion detecting circuit sets a threshold value indicating a charging completion current value to a threshold value being higher than an ordinary threshold value. A current detecting circuit detects a value of a current flowing from a charging terminal to a charging current detecting resistor and the charging completion detecting circuit judges whether a current value detected by the current detecting circuit has reached the set threshold value.

  • Patent number: 5745859
    Abstract: A portable radio telephone device has a main telephone unit and a microphone-speaker/headphone set connected to the main telephone unit by a curled cord cable. The microphone-speaker/headphone set includes a transmitter amplifier and a receiver amplifier which function as differential amplifiers for amplifying the difference between an AC component on a voice signal ground line connected to the main telephone unit and the transmitted and received voice signals, respectively. Variations (AC component) in the ground level of the main telephone unit are added to the voice signals to cancel noise produced in the voice signals even when periodic level variations are developed between the ground levels of the microphone-speaker/headphone set and the main telephone unit.

  • Patent number: 5400341
    Abstract: In a control device for controlling a CPU 11 in accordance with an input voltage which is applied to the CPU and which results from a power source voltage, a first detecting circuit 16 produces a first detection signal when the power source voltage is lower than a first voltage. Responsive to the first detection signal, a switching circuit 21 stops supply of the input voltage to the CPU and the CPU assumes to a waiting state. A condenser 15 discharges an electric voltage in order to compensate a drop of the input voltage. When the input voltage is lower than a second voltage which is lower than the first voltage, a second detecting circuit 17 produces a second detection signal to make the CPU become a reset or an initial state.

  • Patent number: 5391928
    Abstract: In a switching circuit for use in a mobile telephone device in controllably transmitting a speech signal to a radio transmission unit through an output terminal (312), a first switch (31) is controlled by a control signal which is supplied to a control terminal (32) with a high level and a low level of putting the first switch in a conductive and a non-conductive state when a second switch (36) is put in its off and on states. A capacitor (35) is connected between the control terminal and the output terminal in order to make the switching circuit have a low output impedance when the first switch is put in its off state.

  • Patent number: 5105458
    Abstract: In a mobile telephone system, a base station establishes a radio link to a mobile station and a connection to a swtiched telephone network when the mobile station is in communication with a network-side station. The base station constantly monitors signals from the mobile station over the radio link. If it detects that the radio link is failing during a communication, an announcement is transmitted to the network-side station. A recording/playback apparatus is then operated to record a message from the network-side station. The base station further includes a ringing detector for detecting a ringing signal from the network when an incoming call is received from a network station. A connection is then established between the calling station and the base station if it fails to access the mobile station. An announcement is then transmitted to the network and the recording/playback apparatus is operated to record a message from the calling station.
