  • Patent number: 10686768
    Abstract: In a profile data delivery control apparatus, a storage unit stores therein a public key and a private key. A control unit obtains profile data including the identification information of a service provided using a server, and when the profile data satisfies a prescribed validity condition, attaches a signature to the profile data using the private key. The control unit embeds the public key to be used to verify the signature, in a client application that causes a client to perform an authentication process based on the profile data, and delivers the client application with the public key embedded.

  • Publication number: 20200026491
    Abstract: A device searches a file being recorded that includes lines sorted in accordance with keys included in the lines to find a line that matches a pattern. When the device receives a pattern, it initializes upper and lower limits of a search range and calculates a middle position between the limits. It acquires, from the file, a middle line that starts at or before the middle position and ends after it. If the key included in the middle line matches the pattern, it outputs the middle line and re-sets the upper or lower limit based on whether the key included in the middle line is greater or less than the pattern and, if there is a distance greater than a length of a newline between the limits, repeats the procedure starting from the middle position. Otherwise, it outputs a result to the effect that no matching line has been found.

  • Publication number: 20190019141
    Abstract: Association means of a logistics system associates authentication information on a user with the package and storing the associated authentication information into a storage means; Instruction means instructs an unmanned aerial vehicle into which the package is to be loaded to move to the location, based on location information on a location of a collection destination or a delivery destination of the package. Arrival determination means determines whether the unmanned aerial vehicle has arrived at the location. Checking means checks whether the user is at the location based on the authentication information associated with the package and on a situation of the location detected by the unmanned aerial vehicle or details of communication to and from a terminal of the user. Movement control means moves the unmanned aerial vehicle toward the user at the location when the checking means confirms that the user is at the location.

  • Publication number: 20080205668
    Abstract: A silicon microphone includes a silicon microphone device, on which four acoustic transducers are integrated, an integrated circuit device and a package for housing the devices in an inner space defined therein, and the four acoustic transducers have different values of sensitivity and, accordingly, different values of dynamic range; the analog acoustic signals are supplied from the four acoustic transducers to the integrated circuit device, and are converted to digital acoustic signals; the digital acoustic signal output from the acoustic transducers with relatively high sensitivity are normalized with respect to the digital acoustic signal output from the acoustic transducer with lowest sensitivity, and the normalized digital acoustic signals are selectively formed into a composite acoustic signal depending upon the sound pressure of sound waves so that the dynamic range is expanded without sacrifice of high sensitivity in the low sound pressure range.

  • Patent number: 5126737
    Abstract: A conversion method converts a first digital signal having a first sampling period to a second digital signal having a second sampling period which is different from the first sampling period. The method comprises four steps. In the first step, the first digital signal is oversampled. In the next step, the sample value of the oversampled signal maintains an identical value during a short period corresponding to a common multiple of the first sampling period and the second sampling period. In the third step, an interpolation process is carried out. Finally, the second digital signal is outputted by sampling at the second sampling period.

  • Patent number: 5101369
    Abstract: A digital filter performs a predetermined arithmetic operation on input digital data inputted thereto in time-series manner by the predetermined first sampling period to thereby generate output digital data corresponding to a second sampling frequency which is N (where N denotes an integral number) times larger than the predetermined first sampling frequency. This digital filter provides a synchronizing signal generating circuit and an operation control circuit. The synchronizing signal generating circuit detects the predetermined first sampling period of the input digital data to thereby generate a synchronizing signal having the second sampling frequency. The operation control circuit is activated by its internal clock which is asynchronous with the input digital data. This operation control circuit starts to perform its operation processes when the synchronizing signal is supplied thereto, thereafter it terminates the operation processes when a predetermined step number is completed.
