Abstract: There is provided a controlling communication system which includes a control device for transmitting a control signal, an object-side communication device mounted on a controlled object for receiving the control signal, and a drive control device for controlling the controlled object, and which can set a failsafe function of the object-side communication device using the control device, wherein a voltage reference value and a detection time reference value set by the control device are transmitted to the object-side communication device and are stored in a memory unit of the object-side communication device, and wherein the object-side communication device judges if the battery state meets a requirement for activating a failsafe function by referring to the voltage reference value and the detection time reference value stored in the memory unit.

Abstract: The present invention provides a steering communication system being able to individually obtain a telemetry data from a steered-object communication devices mounted on the steered-object. An arbitrary identification number assigned to a plurality of steered-object communication devices mounted on a steered-object at the time of pairing-setup is associated with the equipment ID of a pairing object. When performing transmission request of a telemetry data, a steering signal adding the transmission request information and the own identification number is transmitted. The steered-object communication device judges signal classification of the inputted control signal. When the steering signal adding transmission request information and the own identification number is inputted, the steered-object communication device transmits a telemetry data signal adding the telemetry data as an answer signal to a steering communication device.

Abstract: In a controlling communication device, parameter of a device mounted in an airframe is modified remotely from a transmitting side without a personal computer or a dedicated setting box. The communication device is operable to select an operation mode and a parameter mode, and includes a controlling communication device (a transmitter) having a display, a controlled body communication device (a receiver) connected to a device mounted in the airframe. In the parameter mode, the parameter signal is transmitted to the receiver by operation of the transmitter, and the parameter of the device is modified remotely by radio while seeing the display. The parameter signal by return from the receiver notifies results of the modification. Even if the device is made plurally in types or in number, it is unnecessary to detach the device from the controlled communication device, so as to readily modify the parameter.

Abstract: A servo device 30 includes: a control portion 31 for driving and controlling a drive mechanism 32 by receiving a control signal from a transmitter 10, and by transforming the control signal into a drive signal corresponding to characteristic data previously stored in a memory portion 35. The control portion 31 includes: a signal processing portion 33 for discriminating whether the control signal is a maneuver signal or a characteristic data signal; and the memory portion for updating and storing the characteristic data based on the received characteristic data signal when the control signal is discriminated as the characteristic data signal.

Abstract: A digital data that includes at least two bits is input to a chirp modulation unit. On the basis of either one of these two bits, a frequency variable range is selected as either a frequency variable range between a frequency f1 and a frequency f2, a frequency variable range between a frequency f2 and a frequency f3 (the frequency f3 is the highest, the frequency f2 the second highest, and the frequency f1 the lowest of these three frequencies). On the basis of the other bit, it is selected whether a frequency is swept to a higher frequency or to a lower frequency within the frequency variable range selected by the one of the two bits.

Abstract: A device is provided that creates pulse signals for UWB with a simplified circuit and performs radio transmission/reception in ultrawideband. The signal processor converts transmission data into a transmission baseband and then transmits it to the Manchester converter circuit. The Manchester converter circuit creates Manchester codes, which are converted from an L level to an H level with bit data [1] of transmission data, or from an H level to an L level with bit data [0] of transmission data. The Manchester converter circuit drives the monopulse generator circuit, using the output monopulse. The monopulse generator circuit includes series resonator circuit, produces a monopulse signal of transient response, which converts from positive to negative or from negative to positive, in response to the edge of the pulse.
