  • Patent number: 7355619
    Abstract: A mobile videophone terminal capable of transmitting display information obtained through data communication and the like to a receiving end while talking on the videophone to display it at both ends in real time. The mobile videophone terminal simultaneously performs voice communication and video communication using a still image or, a moving image. Further, the mobile videophone terminal has a multiaccess function for performing videophone communication and data communication at the same time. The mobile videophone terminal at a transmitting end transmits display information obtained through data communication by the use of the multiaccess function or display information in which the display information thus obtained is combined with another display information as a transmitting image to a receiving end. By this means, it becomes possible to share the display information obtained by the use of the multiaccess function with each other in real time.

  • Patent number: 7085538
    Abstract: The invention provides a portable communication terminal with an image transmission function which can convey a reception electric field intensity state of and generation of a communication quality alarm in the portable communication terminal itself in the form of an image to the opposite party of communication. A control section controls a display section to display a reception electric field intensity of the portable communication terminal in accordance with an electric field intensity information signal from a radio communication function section. During image communication, an electric field intensity display image is transmitted as a transmission image together with an image picked up by an image pickup section. If a communication quality alarm is generated by the control section because of deterioration of the circuit quality during the communication, then an alarm image stored in advance in a memory is transmitted together with or in place of the image picked up by the image pickup section.

  • Patent number: 6483622
    Abstract: In a mobile data terminal having an infrared communication capability, a battery capacity detection 4 determines whether or not the remaining capacity of a battery 5 is smaller than a preselected threshold value. If the remaining capacity is greater than the threshold value, a data processing 1 causes a drive current control 3 to feed a first preselected drive current to a light emitting device 21 included in an infrared communication function 2. If the remaining capacity is smaller than the threshold value, the data processing 1 causes the drive current control 3 to feed a second preselected drive current smaller than the first drive current to the light emitting device 21. As a result, when the remaining battery capacity is small, a distance which infrared rays reach is reduced in order to maintain the infrared communication capability. A decrease in the above distance is reported to the user of the data terminal via an output 8 for thereby insuring convenient use.

  • Patent number: 6263449
    Abstract: There is provided a data processor having radio communication function, including (a) a clock generator for selectively generating clock signals having different frequencies, (b) a signal quality analyzer for analyzing quality of a received signal by comparing quality of a received signal to a predetermined threshold level, and (c) a frequency controller for causing the clock signals to have an ordinary frequency when the quality of a received signal is judged not to degrade, and causing the clock signals to have a second frequency smaller than the ordinary frequency, when the quality of a received signal is judged to degrade. In accordance with the data processor, when quality of a received signal is judged to degrade, based on an intensity of an electric field, a frequency of clock signals is caused to decrease. Hence, it is possible to reduce noises caused by clock signals, enhancing reliability in radio communication.

  • Patent number: 6122330
    Abstract: A radio receiver receives a plurality of 4-ary FSK signal replicas and detects a four-level detected signal from each 4-FSK signal replica. The four-level detected signal is sampled by an AD converter. When a first signal replica is received before a second signal replica, a first distance between a first sample value and an input center level of the AD converter and a second distance between a second sample value and the input center level are calculated. The first sample value corresponds to the first sample value in the first and second signal replicas, respectively. One of the first sample value and the second sample value is selected depending on which one of the first and second distances is larger than the other.

  • Patent number: 5909074
    Abstract: The present invention is provided with a motor having a rotary shaft. A weight is fixed to a motor through guide pins formed to the rotary shaft. Each of springs has one end connected to the rotary shaft and the other end connected to the weight. The guide pins guide the vertical movement of the weight with respect to the rotary shaft. Holes are formed in the weight and the guide pins are pierced therethrough. A hook is formed to a tip of each guide pin to prevent the weight from coming off the guide pins when the weight is rotated. With the above-described arrangement, in the vibration motor according to the present invention, the eccentric quantity of the weight with respect to the rotary shaft becomes small by the springs when the rotation of the weight is started. The starting torque of the motor can be, therefore, small.
