    • A two terminal line voltage thermostat includes a switch which connects one side of the line voltage to a heater load (that it drives) such as a baseboard heater with the other side of the heater being connected to the other side of the line. Common full wave rectifier components drives both a relay coil and the remaining electronics of the thermostat. In addition, an arc suppressing triac across the switch while necessarily connected to the primary side of a transformer is directly driven from the secondary which is ungrounded; the primary also provides choking for the triac.

    • A method for dynamically balancing a rotating system through strategic control model updates, wherein said system contains sensors and sensor measurements whose responses to control actions are used to represent the system through a control model, where said control model and sensor measurements are used to determine future control actions is disclosed. The performance of the control model is evaluated using sensor measurements and responses; the evaluation is further used to determine if it is necessary to update the control model. The ongoing performance of the current control model is anticipated utilizing rate-of-change metrics obtained by evaluating said sensor measurements and responses. When a new control model is needed, further evaluation is done to determine if sensor measurements and responses are adequate for updating the control model. When control model performance is poor and past control actions not adequate to update the control model or when system-operating conditions have changed substantially and control performance is questionable, select control actions are computed. These control actions excite the rotating system to provide sufficiently different sensor measurement response adequate to update the control model. In both cases, the select control action minimizes the negative effects on the balance system. The performance evaluations and select control actions are incorporated into a balance control procedure, thereby improving balance times and facilitating achievement of maximum spin speeds in a self-balancing system.
    • 一种用于通过战略控制模型更新动态平衡旋转系统的方法,其中所述系统包含传感器和传感器测量,其对控制动作的响应用于通过控制模型表示系统,其中所述控制模型和传感器测量用于确定未来 公开了控制措施。 使用传感器测量和响应评估控制模型的性能; 评估进一步用于确定是否需要更新控制模型。 使用通过评估所述传感器测量和响应而获得的变化率度量来预期当前控制模型的持续性能。 当需要新的控制模型时,进行进一步的评估以确定传感器测量和响应是否足以更新控制模型。 当控制模型性能较差时,过去的控制动作不足以更新控制模型,或者当系统运行条件发生了显着变化并且控制性能有问题时,则选择控制动作。 这些控制动作激励旋转系统,以提供充分不同的传感器测量响应,足以更新控制模型。 在这两种情况下,选择控制动作最大限度地减少对平衡系统的负面影响。 性能评估和选择控制动作被并入平衡控制过程中,从而提高平衡时间,并有助于实现自平衡系统中的最大旋转速度。
