    • Circuit modules for providing digital or analog outputs from computational devices in such a manner that the components of the output circuit modules are tolerant of malfunctions in one or more of the components. In the digital output embodiment of the invention, output signals are independently derived using two voting circuits and are then applied to two switches connected in series to provide a fail-safe condition for most types of failure of the switches or the voting circuits. Two identical modules provide the ability to faithfully follow commanded on or off signals in all but a statistically small number of situations, and permit convenient replacement of a defective module without affecting output through the other module. In an analog output module, two independent voting circuits provide voted digital outputs to separate digital-to-analog converters, the outputs of which are compared to generate a validity signal that is used to control an output switch. The validity signal for the module can be combined logically with the switch status of another identical module, to determine which of the modules should be activated by closure of its output switch. An inactive module can be removed and replaced without affecting the integrity of the analog output signals.
    • 用于从计算设备提供数字或模拟输出的电路模块,使得输出电路模块的组件能够容忍一个或多个组件中的故障。 在本发明的数字输出实施例中,使用两个投票电路独立地导出输出信号,然后将其应用于串联连接的两个开关,为开关或投票电路的大多数类型的故障提供故障安全条件。 两个相同的模块提供了在统计学上很少数量的情况下忠实地遵循所指示的开或关信号的能力,并且允许方便地更换有缺陷的模块而不影响通过另一模块的输出。 在模拟输出模块中,两个独立的投票电路提供投票数字输出以分离数模转换器,将其输出进行比较以产生用于控制输出开关的有效信号。 模块的有效信号可以逻辑地与另一个相同模块的开关状态组合,以确定哪个模块应通过关闭其输出开关来激活。 可以移除和更换非活动模块,而不影响模拟输出信号的完整性。

    • A protected digital output circuit coupled to a programmable controller, for controlling a load supplied through alternating-current (ac) power lines, including a fuse and a single controlled output switch connected in series with the load, and a pair of series-connected crowbar switches connected together across the ac power lines. The crowbar switches can be commanded closed together in the event that the output switch is commanded open but fails to open, thereby shorting the ac power lines and disconnecting the load by blowing the fuse. In routine diagnostic testing, the crowbar switches can be commanded closed separately to check their operation without blowing the fuse. A current detection circuit is used to check for current in the closed crowbar switch. A current sensor is also used to detect current through the output switch, when commanded closed for switching the load on, or for diagnostic turn-on testing when the load is disconnected.
    • 耦合到可编程控制器的受保护的数字输出电路,用于控制通过交流(ac)电力线提供的负载,包括与负载串联连接的保险丝和单个受控输出开关,以及一对串联连接的撬棒 交流电源线连接在一起的开关。 如果输出开关被指令打开但不能打开,则可以将撬棍开关关闭在一起,从而通过吹保险丝来短路交流电源线并断开负载。 在常规诊断测试中,撬棍开关可以单独指令关闭,以检查其操作,而不会熔断保险丝。 电流检测电路用于检查封闭的撬棍开关中的电流。 当负载断开时,电流传感器还用于检测通过输出开关的电流,当指令关闭以打开负载或进行诊断开启测试。

    • A mobile chair for the handicapped includes a seat frame, a front support frame and a removable rear support frame. The seal frame is pivotable with respect to the front support frame selectively to vary the position of the seat frame. The rear support frame is releasable from the front support frame and is connected thereto by a toggle mechanism at the rear and a pivotal releasable ball and socket joint at the front. To place the chair in a car or other vehicle, the front of the chair is first placed on the vehicle floor, the rear toggle connection is released and the seat frame and front support frame are placed on the vehicle seat. The ball and socket joint permits the seat frame and front support frame to be pivoted into the car and placed on the seat while the rear support frame remains essentially stationary outside the vehicle. Once the chair is in the vehicle, the ball and socket connection is released and the rear support frame may be removed and stowed elsewhere.

    • A switch module for connection between a power source and a controlled load, and a method for its operation, the switch module being testable without regard to the nature of the load, the nature of the power source, or whether the switch is actually connected to the power supply and its controlled load. The switch module has two pairs of MOS FET solid state switches, each pair connected back-to-back to allow switching of alternating current (ac) as well as direct current (dc) in either direction. Each pair of switches in the module has an associated independent power source, which is used in the preferred embodiment of the invention to supply a control signal to each switch and to supply a test current through the switch when it is closed. Test pulses invert the state of each switch momentarily and corresponding test current pulses are observed if a switch is operating properly. A missing switch-off pulse when the switch module is connected to a load circuit may be caused by the presence of an inductive load, and this is assumed to be case if there is a missing pulse in both pairs of switches. Generating at least two closely spaced test pulses allows elimination of errors arising when one pulse is generated too close to a current zero crossing in an ac circuit.
    • 用于电源和受控负载之间的连接的开关模块及其操作方法,所述开关模块可以在不考虑负载的性质,电源的性质,或者开关是否实际连接到 电源及其受控负载。 开关模块具有两对MOS FET固态开关,每对对背连接,允许交流电(AC)以及直流(dc)在任一方向上切换。 模块中的每对开关具有相关联的独立电源,其在本发明的优选实施例中用于向每个开关提供控制信号,并且当关闭时通过开关提供测试电流。 测试脉冲立即反转每个开关的状态,并且如果开关正常工作,则观察到相应的测试电流脉冲。 当开关模块连接到负载电路时,缺少关断脉冲可能是由感性负载的存在引起的,如果在两对开关中存在缺失脉冲,则假设情况是这样。 产生至少两个紧密间隔的测试脉冲允许消除当一个脉冲产生太接近交流电路中的电流过零时产生的误差。
