摘要:
An optical fiber inspecting system comprises a waveform measuring unit for measuring an OTDR waveform for an optical fiber and a waveform evaluating unit for evaluating an anomaly within the optical fiber through a use of the measured waveform. The waveform evaluating unit comprises a calculating part and a detecting part. The calculating part calculates the gradient and the amount of change in gradient of the waveform at each time point by means of a gradient calculating section and a gradient change amount calculating section. The detecting part determines whether or not the gradient and the amount of change in gradient are within a defined allowable range of gradient and a defined allowable range of amount of change, respectively, by way of a gradient determining section and a gradient change amount determining section.

An optical fiber inspecting system 1A comprises a waveform measuring unit 2 for measuring an OTDR waveform for an optical fiber F to be inspected and a waveform evaluating unit 3 for evaluating an anomaly within the optical fiber through a use of the measured waveform. Furthermore, the waveform evaluating unit 3 comprises a calculating part 4 and a detecting part 5. The calculating part 4 calculates the gradient and the amount of change in gradient of the waveform at each time point by means of a gradient calculating section 41 and a gradient change amount calculating section 42. The detecting part 5 determines whether or not the gradient and the amount of change in gradient are within a defined allowable range of gradient and a defined allowable range of amount of change, respectively, by means of a gradient determining section 51 and a gradient change amount determining section 52. This realizes an optical fiber inspecting system, an inspection method and a selecting method, all of which enable to detect reliably an anomaly within an optical fiber through an OTDR waveform.

A timing generator includes a frame rate information receiver, a display control section, and a determination unit. The frame rate information acquisition section is configured to receive information indicating a frame rate of an image sensor. The display control section is configured to output dot clocks in a first cycle to a display which includes a counter being configured to count the number of the dot clocks for a synchronization period, where the dot clocks are a synchronization signal. The determination unit is configured to determine whether or not the number of the dot clocks in the synchronization period is expected to exceed a predetermined number, where length of the synchronization period is based on at least the frame rate of the image sensor. The display control section is configured to switch from the first cycle to a second cycle, if the number of dot clocks is expected to exceed the predetermined number.

A memory controller including: a rectangular area designation register which is used for designating a rectangular area inside a display area; an address generation circuit which generates an address of the memory corresponding to a position of each pixel inside the rectangular area; a color designation register in which designated pixel data is designated; and a bit block transfer control register. When the bit block transfer is enabled, the memory controller writes the designated pixel data in the memory based on the address generated by the address generation circuit corresponding to a bit block transfer rectangular area. When the bit block transfer is disabled, the memory controller writes input pixel data in the memory based on the address generated by the address generation circuit corresponding to an input pixel data transfer rectangular area.

摘要:
A vehicle notification sound emitting apparatus is basically provided with a sound emitting device and a notification sound control device. The sound emitting device emits a starting movement notification sound to outside of a vehicle to inform a person in an outside area surrounding the vehicle that the vehicle will transition from a stopped state to a moving state, and emits a moving notification sound to outside of the vehicle to inform a person in the outside area surrounding the vehicle that the vehicle is moving. The notification sound control device operates the sound emitting device to selectively emit the starting movement notification sound. The notification sound control device includes a notification sound emission timing section that sets a start timing of the starting movement notification sound in response to a shift operation having been performed and an additional start movement preparation operation of the vehicle having been performed.

The sound emitting device is configured to emit a movement notification sound to outside of a vehicle to inform a person in an area surrounding the vehicle that the vehicle will move. The notification sound control device is configured to operate the sound emitting device to emit a movement notification during a period from when a vehicle speed becomes equal to or smaller than a prescribed value until a prescribed amount of time has elapsed in a situation where the vehicle speed becomes equal to or smaller than the prescribed value while the forward movement notification sound is being emitted.

A vehicle notification sound emitting apparatus is basically provided with a sound emitting device and a notification sound control device. The sound emitting device emits forward and reverse advancement notification sounds outside of a vehicle to inform a person in an area surrounding the vehicle that the vehicle will move. The notification sound control device operates the sound emitting device to selectively emit the forward and reverse movement notifications. The notification sound control device includes forward and reverse advancement notification sound emission timing sections. A start timing of the forward advancement notification sound is set in response to both a forward movement shift operation having been performed and an additional start movement preparation operation of the vehicle having been performed. A start timing of the reverse movement notification sound is set to be emitted immediately in response to the reverse movement shift operation having been performed.
