    • An intensity modulated radio therapy (IMRT) dosimeter measuring a three-dimensional absorption dose distribution in a transparent plastic phantom readily and accurately. In the IMRT dosimeter, radiation beams are directed to a phantom assembly having a scintillation fiber block sandwiched between two blocks of the phantom. As an intensity of light proportional to the radiation beam is emitted from one side of the scintillation fiber block, its profile is measured by an image sensor. Then, the three-dimensional absorption dose distribution is obtained from the light intensity distribution data. By summing the three-dimensional absorption dose distribution data measured with the radiation beam at different angles, an integrated three-dimensional absorption dose distribution in the phantom can be calculated readily and accurately.
    • 强度调制放射治疗(IMRT)剂量计容易且准确地测量透明塑料体模中的三维吸收剂量分布。 在IMRT剂量计中,辐射束被引导到具有夹在两个模体块之间的闪烁纤维块的幻影组件。 由于与闪光纤维块的一侧发射与辐射束成比例的光的强度,其轮廓由图像传感器测量。 然后,从光强分布数据获得三维吸收剂量分布。 通过用不同角度的辐射束测量的三维吸收剂量分布数据相加,可以容易且准确地计算体模中的一体化三维吸收剂量分布。

    • A security apparatus for a vehicle including a transmitting device and a receiving device either of which is mounted on the vehicle, the security apparatus including a control section for altering a processing mode of one of the transmitting device and the receiving device when an operation switch mounted on the vehicle is operated in an abnormal fashion. The operation switch may be a radio ON/OFF switch or an ignition switch, and the abnormal operation may be turning on and off the switch a predetermined number of times within a predetermined period. When this abnormal operation is detected by the control section, the control section permits the identification code of the security apparatus to be rewritten with a new identification code transmitted from the other of the transmitting device and the receiving device.
    • 一种用于车辆的安全装置,包括发送装置和安装在车辆上的接收装置,所述安全装置包括控制部分,用于当安装的操作开关时改变发送装置和接收装置之一的处理模式 在车辆上以异常的方式操作。 操作开关可以是无线电开/关开关或点火开关,并且异常操作可以在预定时间段内将开关接通和断开预定次数。 当由控制部检测到这种异常操作时,控制部分允许用从发送装置和接收装置中的另一个发送的新的识别码重写安全装置的识别码。
