  • Publication number: 20160332002
    Abstract: An irradiation apparatus attached to a rotary gantry includes a middle housing unit and a lower housing unit. Touch sensor apparatuses are attached to a middle housing unit, and touch sensor apparatuses are attached to a lower housing unit. The touch sensor apparatus includes a cover, a pair of cover support apparatuses for attaching the cover to a support member of the middle housing unit, and a sensor unit attached to each cover support apparatus. When the cover comes into contact with a bed and moves toward the support member during rotation of the irradiation apparatus, a link such as a cover support apparatus activates the sensor unit, and a contact signal is output. The touch sensor apparatuses also function in the same manner.

  • Patent number: 7504991
    Abstract: Disclosed is a distance measuring system comprising a transmitter that sequentially generates pulse sequences each having a plurality of pulse signals of equal amplitudes arranged at equi-time intervals, and transmits the generated pulse sequence as a radio wave; and a receiver that receives the pulse sequence transmitted from the transmitter as a radio wave, and has a distance calculator that acquires propagation times of the pulse signals in the received pulse sequence, and calculates a distance from the transmitter by giving different weightings to the pulse signals for the propagation times acquired for the respective pulse signals. As the amplitudes of the pulse signals in the received pulse sequence become larger, the weightings are made larger.
