摘要： A controller suitable for identifying an abnormal operational condition in a bathing system is provided. The controller includes a processing unit for detecting an abnormal operational condition associated with the bathing system. In response to detection of an abnormal operational condition, the processing unit causes a ground fault circuit interrupter (GFCI) associated to the bathing system to trip. In a first example, the controller includes a memory unit adapted for storing measurements indicative of electrical currents drawn by respective bathing unit components under normal operating conditions. The processing unit is adapted for detecting an abnormal operational condition associated with the bathing system at least in part based on measurements stored on the memory unit. In a second example, the controller includes a plurality of actuators associated to respective bathing unit components operative for causing bathing unit components to acquire either one of the actuated state or the non-actuated state. The processing unit is adapted for detecting an abnormal operational condition associated with one or more actuators in the plurality of actuators.

摘要： A method for controlling charging and discharging of a piezoelectric actuator for use in a fuel injector having an inject mode (12) and a non-inject mode (16); comprises applying a charging current of variable amplitude to the actuator during a charge mode (14), wherein the amplitude of the charging current varies with a first PWM frequency, and applying a discharging current of variable amplitude to the actuator during a discharge mode (10), wherein the amplitude of the discharging current varies with a second PWM frequency. The charging current and/or the discharging current is monitored during the charge and discharge modes (10, 14), respectively, and the discharging current and/or the charging current is controlled in response to the monitored current. The first and/or second PWM frequency is varied throughout the discharge mode (10) and/or the charge mode (14), respectively, so as to suppress resonance modes within the actuator.

摘要： A controller suitable for identifying an abnormal operational condition in a bathing system is provided. The controller includes a memory unit adapted for storing measurements indicative of electrical currents drawn by the bathing system under normal operating conditions, each measurement being indicative of the electrical current being drawn by a respective bathing unit component in the bathing system. The controller also includes a processing unit for modifying the measurements stored in the memory unit and for detecting an abnormal operational condition associated with the bathing system at least in part on the basis of measurements stored on the memory unit. In specific implementations, sensing circuitry adapted for obtaining measurements associated to components, such as relays and fuses, is provided. This sensing circuitry allows identify components on the controller, such as relays and fuses for example, and bathing unit components in the bathing system as potential causes of an abnormal operational condition associated with the bathing system.

摘要： A method of operating a fuel injector including a piezoelectric actuator having a stack of piezoelectric elements, comprises applying a discharge current (IDISCHARGE) to the actuator for a discharge period so to discharge the stack from a first differential voltage level across the stack to a second, lower differential voltage level across the stack so as to initiate an injection event, and applying a charge current (ICHARGE) to the actuator for a charge period (T3 to T4′) so as to charge the stack from the second differential voltage level to a third differential voltage level so as to terminate the injection event. The method includes determining at least one engine parameter (e.g. common rail pressure) of the injection event prior to applying the charge current (ICHARGE) to the actuator and selecting the third differential voltage level in dependence on the at least one engine parameter.
