    • A sensor transmits and receives wireless signals at intervals. A sensor unit, a processor 130, a wireless transmitter circuit, and a wireless receiver circuit are activated in sequence only for a fixed time when the electric power generated by a generator circuit and charged in a capacitor reaches a preset level. Sensing information detected by the sensor unit is processed by the processor circuit and, information on the number of receivable bytes is added to the processing results in the wireless receiver circuit. This added information is sent as sensor information to the wireless host from the wireless transmitting circuit, and the wireless receiver circuit that activated after the wireless transmitter circuit was activated, receives a control information signal from the wireless host. This received information is processed in the processor circuit.
    • 传感器间隔地发送和接收无线信号。 传感器单元,处理器130,无线发射器电路和无线接收器电路仅在发电机产生的电力并在电容器中充电的电力达到预设电平的固定时间内被依次激活。 由传感器单元检测到的感测信息由处理器电路处理,并且关于可接收字节数的信息被添加到无线接收器电路中的处理结果。 该添加的信息作为传感器信息从无线发送电路发送到无线主机,并且在无线发射机电路被激活之后激活的无线接收机电路从无线主机接收控制信息信号。 该接收到的信息在处理器电路中被处理。

    • A cylinder discriminating device includes a cylinder discriminating section. A crank rotor includes first and second non-tooth portions asymmetrically positioned on the crank rotor. The first non-tooth portion is positioned to correspond to a top dead center of a specific cylinder. A crank signal is outputted when each of the plurality of the tooth portions is detected. A cam signal is outputted when a predetermined tooth portion of a cam rotor is detected. And, the cylinder discriminating section discriminates the specific cylinder by detecting the first non-tooth portion based on number of the crank signals detected during a time period from a time when one of the first and second non-tooth portions is detected to a time when the other of the first and second non-tooth portions is detected, and by detecting whether or not the cylinder discriminating section detects the cam signal during the same time period.
    • 气缸鉴别装置包括气缸鉴别部分。 曲柄转子包括不对称地定位在曲柄转子上的第一和第二非齿部分。 第一非齿部被定位成对应于特定气缸的上止点。 当检测到多个齿部中的每一个时,输出曲柄信号。 当检测到凸轮转子的预定齿部时,输出凸轮信号。 并且,气缸识别部通过基于从检测到第一和第二非齿部中的一个时刻到时间期间检测到的曲柄信号的数量来检测第一非齿部分来识别特定气缸, 检测第一和第二非齿部分中的另一个,并且通过检测气缸识别部分是否在同一时间段内检测到凸轮信号。

    • A focus detecting device for performing focus detection of passive type using phase-difference detection includes a sensor composed of a plurality of pixels which are paired, and a judgment circuit for judging whether a target image for focus detection is a thin line close to a pixel pitch of the sensor, on the basis of a correlation varying amount of two images formed divisionally on the sensor and an output difference of adjacent pixels of each of the two images, so that it is possible to cope with the thin-line image.
