    • A photodetector is provided, which has the capability of preventing a reduction in dynamic range for a signal light even under a plenty of environmental light to stably obtain a received light output. This photodetector has an accumulation electrode and a holding electrode, which are formed on a photoelectric converting portion through an insulating layer, and a control unit for controlling timings of applying voltages to these electrodes and polarities of the voltages. One of electrons and holes generated in the photoelectric converting portion is accumulated in an accumulation region formed by applying the voltage to the accumulation electrode, and the other is accumulated in a holding region formed by applying the voltage to the holding electrode. Then, the electrons and holes accumulated in the accumulation region and the holding region are recombined, so that remaining electrons or holes not recombined are output.

    • An infrared detecting device. The device includes a drive power supply circuit which supplies a drive current to each of signal circuits comprised of an I/V conversion circuit, a voltage amplification circuit, a detection circuit and an output circuit. The drive power supply circuit is comprised of a current generating circuit and a distribution circuit. The current generating circuit includes a reference current source, a fixed current source which provides a fixed current based on reference current and a variable current source which provides a variable current stepped up or down to any of different currents based on the reference current. The distribution circuit distributes the drive current to a part of the signal circuits based on the current from the fixed current source and distributes the drive current to a remaining part of the signal circuits based on the current from the variable current source. The device reduces current consumption while keeping the performance or behavior of the circuits in stable state.

    • A spatial information detecting apparatus using an intensity-modulated light has a photoelectric converter for receiving a light provided from a space, into which a light intensity-modulated by a predetermined modulation signal is being irradiated, and generating amounts of electric charges corresponding to an intensity of received light; charge discarding portion having an electrode for removing dispensable charges from the electric charges generated by the photoelectric converter according to a voltage applied to the electrode; charge storage portion for storing signal charges from the electric charges generated by the photoelectric converter; control circuit for controlling the voltage applied to the electrode at a timing synchronized with a period of the modulation signal to change a ratio of the signal charges stored in the charge storage portion to the electric charges generated by the photoelectric converter; charge ejector for outputting the signal charges from the charge storage portion; and an analyzer for determining spatial information from an output of the charge ejector. According to this apparatus, since the dispensable charges are previously removed from the electric charges generated by the photoelectric converter by the charge discarding portion, it is possible to improve S/N ratio and accurately determine the spatial information.

    • A number of sets of software may be systematically distributed and maintained via a network connecting many vendors and users of client/server software. A client program in a user computer detects when software subject to maintenance is activated and transmits an inquiry over the network to the software vendor's computer for information on the current version of the software. The server program compares data in the inquiry with data relating to the latest version of the software and returns update instruction information and updated software if appropriate. The client program automatically updates the software to the latest version according to the update instruction information when it is received. The client program can also send inquires at predetermined times, or in response to a user command. The inquiry can include a request for purchase information in which case the server checks qualifications of the user, processes the inquiry according to vendor management data and returns the requested software, if appropriate. Other inquiries can also be made in response to user commands or automatically, e.g., to obtain information on the most recent version and transmission of data from client to server in response to an abnormal termination of client software.
