  • Publication number: 20240089065
    Abstract: Provided is a radio communication device which can prevent interference between SRS and PUCCH when the PUCCH transmission bandwidth fluctuates and suppress degradation of CQI estimation accuracy by the band where no SRS is transmitted. The device includes: an SRS code generation unit (201) which generates an SRS (Sounding Reference Signal) for measuring uplink line data channel quality; an SRS arrangement unit (202) which frequency-multiplexes the SRS on the SR transmission band and arranges it; and an SRS arrangement control unit (208) which controls SRS frequency multiplex so as to be uniform in frequency without modifying the bandwidth of one SRS multiplex unit in accordance with the fluctuation of the reference signal transmission bandwidth according to the SRS arrangement information transmitted from the base station and furthermore controls the transmission interval of the frequency-multiplexed SRS.

  • Patent number: 7889170
    Abstract: A force feedback apparatus of the present invention includes: jetting means that includes a nozzle and that can control a jet amount or a jet direction of gas or liquid jetted from the nozzle; jet control means for controlling the jet amount or the jet direction of the gas or the liquid according to a position or an orientation of a receiver that receives pressure by the gas or the liquid jetted from the jetting means so as to provide force feedback to an operator. When the receiver has a concave shape of a diameter D, intervals for placing the nozzles in the jetting means are set such that at least one nozzle exists within a region having a diameter of a constant×D.

  • Patent number: 5864753
    Abstract: A radio station tuning system enables a radio receiver installed in a vehicle to be automatically tuned to a radio station offering a desired program. In the system, a controller receives data recognized by a speech recognizing unit and a current position of the vehicle detected by a navigation unit, provides the data to a communication unit, turns a radio receiver on or off, and tunes the radio receiver to a desired radio station. The communication unit sends data to a base station data via a vehicle telephone line. Receiving the data, the base station has access to its data base storing program data (e.g. broadcasting time, frequencies and so on), retrieves desired data, and transmits them to the vehicle. The controller automatically tunes the radio receiver to the desired radio station on the basis of the received data.

  • Patent number: 4415818
    Abstract: The programmable sequential logic circuit device is constructed to sequentially form an output signal to an external circuit and the circuit state for the next operation in accordance with input signals applied from outside and the internal state of the circuit. The device includes a first logic array for producing product terms of the input signals, a second logic array for producing sum terms of the first logic array, a two-dimensionally arrayed flip-flop array and means for setting the state of the flip-flop array. The flip-flop array is arranged in a plurality of rows of stages each including a plurality of serially connected flip-flop circuits. The inputs of respective rows are connected to the outputs of the second logic array, the outputs of the setting means are applied to the inputs of respective stages and the outputs thereof are parallelly fed back to the first logic array.
