    • An identification transmission system for use in an amusement device includes a transmitting antenna, a transmitter and a piezo-electric power source. The transmitter circuit is configured to broadcast a predetermined tone on a predetermined carrier frequency through the antenna. The piezo-electric power source is electrically coupled to the transmitter circuit and is configured to at least briefly provide power to the transmitter circuit. The piezo-electro power source includes a piezo-electric element, a striker, a storage capacitor and a voltage controlled switch. The striker is configured to move so as to at least briefly strike the piezo-electric element. The storage capacitor is configured to receive and store electrical charge from the piezo-electric element. The voltage controlled switch is configured to allow the storage capacitor to discharge through the transmitter circuit thereby providing power thereto after a predetermined amount of charge has been stored.

    • A communication scheme is employed for transmitting control signals from a remote control to a toy vehicle. The remote control includes control switches, an encoder and a transmitter and the toy vehicle includes a receiver, a decoder and actuators for controlling the operation of the toy vehicle in accordance with received control signals. The encoder generates a continuous stream of control signal packets with each of the packets including a predetermined number of biphase encoded bits. Each biphase encoded bit is of the same predetermined width with a 50% duty cycle, including two transmit elements. For one binary state, both of the transmit elements are the same and for the other binary state both of the transmit elements are opposite. Each packet includes a first predetermined number of flag bits, a second predetermined number of data bits and at least one checksum bit.
    • 采用通信方式将控制信号从遥控器发送到玩具车。 遥控器包括控制开关,编码器和发射器,并且玩具车辆包括接收器,解码器和用于根据接收的控制信号控制玩具车辆的操作的致动器。 编码器产生连续的控制信号分组流,每个分组包括预定数量的双相编码比特。 每个双相编码位具有相同的预定宽度,占空比为50%,包括两个发送元件。 对于一个二进制状态,两个发送元件都是相同的,对于另一个二进制状态,两个发送元件都相反。 每个分组包括第一预定数量的标志位,第二预定数量的数据位和至少一个校验和位。

    • A hybrid sphygmomanometer comprises: (a) an arm cuff with an inflatable air bladder; (b) a pumping device for inflating the air bladder; (c) a manually controlled air outlet valve for deflating the air bladder; (d) an air pressure transducer operative to receive the pressure in the air bladder of the arm cuff and to produce an electrical signal representing this pressure; (e) a manually operated switch for generating systolic and diastolic interrupt signals; (f) a first electronic display for displaying the instantaneous pressure in the air bladder in the form of a bar graph; (g) a second electronic display for displaying systolic and diastolic pressures; and (h) an electrical circuit connected to the pressure transducer and to the button for controlling said first and second display. The first display, for displaying the instantaneous pressure in the air bladder, is a simulated mercury column. The electrical circuit provides an output of digital signals, representing the systolic and diastolic pressures, for use by a programmed digital computer for storage and processing. It also provides an output of manually or digitally entered patient identification data.
