摘要:
An error detecting apparatus can diagnose what is happening with the line through which the image signal is passed, and determine a cause of trouble when the line diagnosed as going out of order. The error detecting apparatus comprises an error detecting circuit for detecting a direct voltage from an output line through which an image signal is outputted to a display apparatus from an image signal outputting apparatus, and a CPU, wherein a zener voltage of a zener diode is within a first range, the CPU is adapted to make a decision that the output line is in the output-line-to-power-line short state when a voltage of a cathode of a zener diode is within the first range, a voltage of the electric potential regulated by a pull-up circuit is within a second range, the CPU is adapted to make a decision that the output line is in the electrically-disconnected state when the voltage of the output line is within the second range, an output voltage of a smoothing circuit is within a third range, the CPU is adapted to make a decision that the output line is in the normal state when the output voltage of the smoothing circuit is within the third range, a reference potential defined by a ground line is within a fourth range, the CPU is adapted to make a decision that the output line is in the output-line-to-ground-line short state.

In a mobile communication terminal for starting and simultaneously using a plurality of applications, one desired application starts fast to improve the operability when the number of started applications reaches a present limiting number of applications. An application start determining unit searches a list of started applications in response to the instruction of the start of application to obtain the number of started applications, and determines that the application cannot start when the number of started applications reaches a preset limiting number of applications. An ending-application selecting unit selects, as an ending application to be ended, the application with the low priority from the start applications based on the preset priority of application when the application start determining unit determines that the application cannot start. An application ending unit performs the ending processing of the ending application selected by the ending-application selecting unit and deletes the selected ending application from the list of started applications.

There is provided a mobile telephone including (a) an antenna receiving radio signals, (b) a display screen, (c) a voltage source, (d) a memory storing telephone numbers therein, (e) an interface through which an operator can set a low-voltage mode in which the mobile telephone is allowed to receive a call associated with predetermined telephone numbers, even if a voltage supplied by the voltage source is equal to or lower than a predetermined threshold voltage, and (f) a controller detecting a telephone number out of a radio signal received through the antenna, comparing the thus detected telephone number to the telephone numbers stored in the memory, and determining whether a call associated with the detected telephone number is to be received, when the mobile telephone is set in the low-voltage mode. The provided mobile telephone makes it possible to receive a call in a predetermined telephone number, even if a voltage supplied from a voltage source is lower than a predetermined threshold voltage.

The Mayday system equipment, installable on an automotive vehicle, is separated into a locator unit which produces vehicle locative information and a communicator unit which produces emergency report information including the vehicle locative information produced by the locator unit. Resultant emergency report information is transmitted to an emergency center. The data/signal transmission between the locator unit and the communicator unit is performed via a cable or by wireless.

An emergency reporting apparatus for a vehicle includes a communication device. In cases where an emergency occurs in the vehicle, the communication device is used to report the emergency to an emergency report receiving center. A user is informed of an operating condition of the communication device when the communication device is used to report the emergency. The communication device may include a radio communication device.

A dot code is provided for recording digital data, such as multi-media information, as an optically readable code pattern, using various modulation methods, and a code reading apparatus is provided for restoring modulated information recorded as the dot code. The dot code includes a plurality of blocks. Each block has a marker section for recognizing the block, a data dot pattern section which is modulated to be structurally discriminated from the marker section and to represent modulated information, and a block header section as a non-modulation area which contains block address data. The block header section stores restoration parameter data necessary to restore the modulated information, thereby enabling the dot code to be variously modulated.

A phase locked loop (PLL) oscillating circuit includes a first oscillating circuit, a lock detector and a reference oscillating circuit. The first oscillating circuit generates an oscillation signal with a first frequency, and controls the first frequency based on a reference signal. The lock detector detects phase lock between the oscillation signal and the reference signal to a lock detection signal. The reference oscillating circuit includes a crystal oscillation element, and generates the reference signal. An oscillation state of the reference oscillating circuit is controlled based on the lock detection signal.
