  • Publication number: 20240134596
    Abstract: The content output device includes an information acquisition unit, a content generation unit and an output unit. The information acquisition unit acquires driving state information which is information related to a current driving state of a vehicle. The content generation unit acquires one or more content elements corresponding to a trigger condition, from among a plurality of content elements combinable with each other, when the driving state information satisfies the trigger condition, and generates an output content using the acquired content elements. The output unit outputs the output content.

    Abstract: A variable delay circuit, which includes a digital-to-time converter (DTC) circuit and a controller, is disclosed. The DTC circuit includes a plurality of capacitors and a plurality of MOS switches that are turned on and off according to a control code. The DTC circuit receives an input pulse, applies a delay corresponding to the control code to the edge to be delayed, and outputs a delay pulse. The controller supplies a valid code indicating a delay amount as a control code during a period beginning from a predetermined time TCONST before the edge (positive edge) to be delayed of an input pulse REF up to the edge to be delayed. Further, the controller supplies, as the control code, a dummy code for turning on all of the plurality of MOS switches inside the DTC circuit immediately before the period.

  • Patent number: 8384450
    Abstract: A frequency synthesizer device that includes two modulation paths and suitably adjusts the amplitude of a control voltage that is outputted from a digital-to-analog converter (DAC) to a voltage-controlled oscillator. The frequency synthesizer device is provided with a voltage-controlled oscillator, a programmable frequency divider, a frequency phase comparator, a DAC, a switch and a modulation frequency displacement correction circuit. The voltage-controlled oscillator oscillates at an oscillation frequency depending on an input voltage. The programmable frequency divider frequency-divides a signal from the voltage-controlled oscillator. The frequency phase comparator outputs a phase difference between the frequency-divided signal and a reference clock. The DAC outputs an adjustment voltage. The switch connects the voltage-controlled oscillator to a reference voltage power source at a time of correction of the adjustment voltage.

  • Patent number: 7328272
    Abstract: A server receives an acquisition request for visual content, such as desired text or image content, from a client terminal via a communication network, and retrieves, from a database, data of the visual content requested by the client terminal. Then, by analyzing the visual content, by referring to an appropriate table or otherwise, the server determines music content or effect tone content to be imparted to the requested visual content in associated relation to specific substance of the requested visual content. Then, the server retrieves data of the determined music content or effect tone content from a database, and transmits the data of the visual content, along with the data of the music content or effect tone content, to the client terminal. On the basis of the data transmitted by the server, the client terminal can not only visually display the requested visual content but also audibly reproduce the music content or effect tone content.
