  • Publication number: 20240121637
    Abstract: A wireless communication monitoring system for monitoring a hardware failure of a wireless communication unit of a wireless communication device using a remote monitoring control device, in which the wireless communication device transmits or receives a predetermined radio signal to or from a monitoring device added or attached to the host device to perform a life and death check for checking an operation, and the remote monitoring control device detects a hardware failure of the wireless communication unit of the wireless communication device on the basis of a result of the life and death check received from the wireless communication device. This makes it possible to detect a failure that cannot be detected from information obtained from a device state request to a wireless communication device of the related art.

  • Patent number: 6614472
    Abstract: There has been raised a problem of how to make the measurement of characteristics of a solid state image pickup device easy to carry out, to shorten the measurement time and to increase the measurement accuracy. In order to solve the problem described above, the solid state image pickup device is operated to generate an output with an operating condition for an odd field made different from that for an even field. For example, a dark signal can be detected with the supply of read pulses for either odd or even fields halted typically at the same time as a playback signal is detected in a state of being shielded from light or a state of applying an incident light with a predetermined quantity. As a result, it is possible not only to measure a variety of characteristics merely under a plurality of conditions at the same time but also to further process outputs of the odd and even fields in order to measure still another characteristic such as a dark current generated by an image pickup area.

  • Patent number: 6563149
    Abstract: Signal charges generated by a plurality of photoelectric conversion elements are transferred to first and second horizontal charge transfer registers via corresponding vertical charge transfer registers. The first and second horizontal charge transfer registers transfer the signal charges to first and second output portions, respectively. The first and second output portions convert the signal charges into voltages. The first and second output portions respectively include first and second signal charge detectors, first and second transistors each having a source, a drain, and a gate, and first and second charge sweeping regions, each having a charge sweeping control gate and a charge sweeping drain.
