摘要： A sensor system includes: a transmission device that includes a sensor which asynchronously outputs detection data including time series information; and a reception device connected to the transmission device via a transmission line. The detection data includes coordinate information, and the transmission device includes an expansion unit configured to expand a value of the coordinate information within a range of the number of bits assigned to the coordinate information, in a case where the detection data is acquired from the sensor, and a transmission unit configured to transmit expanded detection data in which the value of the coordinate information is expanded by the expansion unit to the reception device via the transmission line.

摘要： Clothing equipment having a visual light communication emitter arranged to communicate a status of the clothing equipment, includes a light emitter arranged to emit flash light which is modulated at at least one target frequency in a dedicated non-visible spectrum, the light emitter including three fixed emitting portions distant from each other by predetermined distances, so as to authenticate the status of the clothing equipment.

摘要： A visual light communication emitter for a vehicle, arranged to communicate a status of the vehicle, includes a first light emitter arranged to emit flash light which is modulated at a first target frequency in a dedicated non-visible spectrum, and a second light emitter arranged to emit flash light which is modulated at a second target frequency in the dedicated non-visible spectrum. A difference between the first target frequency and the second target frequency is predetermined, so as to authenticate the status of the vehicle.
