    • A simple and flexible over-air protocol for use with a mobile telephone system, having hand-held telephones in a microcell or other type of cellular communication system. A method in which user stations communicate with one or more base stations to place and receive telephone calls, in which the user stations are provided a secure voice or data link and have the ability to handoff calls between base stations while such calls are in progress. Each base station has a set of “air channels” to which it transmits in sequence. The air channels supported by each base station are called that base station's “polling loop”. A user station receives general polling information on an unoccupied air channel, transmits responsive information to the base station, and awaits acknowledgment from the base station Each base station may therefore simultaneously maintain communication with as many user stations as there are air channels in its polling loop. The ability of a user station to communicate on any unoccupied air channel makes the protocol air-channel agile, while the stability of user station and base station clocks may define air channels, gaps, and minor frames.
    • 一种与移动电话系统一起使用的简单灵活的空中协议,在微小区或其他类型的蜂窝通信系统中具有手持电话。 一种方法,其中用户站与一个或多个基站进行通信以放置和接收电话呼叫,其中向用户站提供安全语音或数据链路,并且具有在正在进行呼叫的情况下在基站之间切换呼叫的能力。 每个基站具有一组依次传输的“空中信道”。 每个基站支持的空中信道称为基站的“轮询循环”。 用户站接收关于未占用空中信道的一般轮询信息,向基站发送响应信息,并等待来自基站的确认。因此,每个基站可以同时保持与其轮询循环中有空中信道的许多用户站的通信 。 用户台在任何未占用的空中信道上通信的能力使得协议空中通道灵活,而用户站和基站时钟的稳定性可以定义空中信道,间隙和次要帧。

    • A stepper-motor gas valve control is disclosed that includes a main diaphragm in a chamber that controllably displaces a valve relative to an opening in response to changes in pressure, to adjust fuel flow through the valve. A servo-regulator diaphragm is provided to regulate flow to the main diaphragm, to thereby control the rate of fuel flow. A stepper motor is configured to move in a stepwise manner to displace the servo-regulator diaphragm, to control fluid flow to the main diaphragm. A controller mounted on the stepper-motor regulated gas valve control receives and converts an input control signal from a heating system to a reference value between 0 and 5 volts, and selects a corresponding motor step value. The control responsively moves the stepper-motor in a step wise manner to displace the servo-regulator diaphragm and thereby regulates the rate of fuel flow through the valve.
    • 公开了一种步进电动机气门控制装置,其包括在腔室中的主隔膜,其响应于压力变化可控制地相对于开口移动阀门,以调节通过阀门的燃料流量。 提供伺服调节器膜片以调节流向主隔膜的流量,从而控制燃料流量。 步进电机被配置为逐步移动以移动伺服调节器膜片,以控制流向主隔膜的流体。 安装在步进电动机调节的气体阀控制器上的控制器接收并将来自加热系统的输入控制信号转换为0至5伏特之间的参考值,并选择相应的电机步进值。 控制器以逐步方式响应地移动步进电机以移动伺服调节器隔膜,从而调节通过阀门的燃料流量。

    • A flow valve that provides for control of a fluid flow rate utilizing a first open position and a second open position. Various embodiments of a flow valve having an inlet, an outlet, and a passageway therebetween are provided that comprise a damper element pivotally arranged within the passageway that is movable between a first position in which fluid flow through the passageway is substantially unaffected by the damper element, and at least a second position in which fluid flow through the passageway is substantially reduced by the damper element. An adjustable stop is further provided for adjustably limiting the movement of the damper element to establish the second position of the damper. A moveable operator is provided for moving the damper element between the first position and second position.
    • 一种流量阀,其利用第一打开位置和第二打开位置来控制流体流量。 提供了具有入口,出口和通道之间的流量阀的各种实施例,其包括枢转地布置在通道内的阻尼元件,该阻尼元件可在第一位置和第二位置之间移动,在第一位置中,流过通道的流体流基本上不受阻尼元件 ,并且至少第二位置,其中通过所述通道的流体流动通过所述阻尼元件显着减小。 还设置有可调节的止挡件,用于可调节地限制阻尼器元件的运动以建立阻尼器的第二位置。 提供了可动操作器,用于在第一位置和第二位置之间移动阻尼器元件。
