Abstract: Techniques involve managing lithium battery access on a utility vehicle. In accordance with such techniques, a wakeup circuit includes a set of inputs, a set of outputs, and control logic coupled with the set of inputs and the set of outputs. The control logic is constructed and arranged to, in response to detecting a wakeup event from circuitry of the utility vehicle via the set of inputs, close a switching apparatus of the utility vehicle via the set of outputs to connect a lithium battery of the utility vehicle to a set of loads of the utility vehicle. The control logic is further constructed and arranged to, in response to detecting a sleep event, open the switching apparatus via the set of outputs to disconnect the lithium battery of the utility vehicle from the set of loads of the utility vehicle.

Abstract: A control device for a piece of powered equipment having an electronic sensor and an electronic control board for controlling the equipment depending on a control signal from the sensor. The electronic sensor is a contactless optical sensor, provided in an interface area of the control device, configured to measure a distance separating at least one target, located in the interface area, and the optical sensor, the electronic board being configured to establish a first control of a main function of the powered equipment, when a signal from the optical sensor is established for a measured distance within a first range of distances, and to establish a control for at least one additional function of the powered equipment, different from the main function, when a signal from the optical sensor is established for a measured distance greater than the first range of distances.

Abstract: A power tool system includes a battery pack, a charger connectable to the battery pack, and a power tool body connectable to the battery pack. The battery pack includes a battery pack memory that stores identification information in a smallest unit allowing for communication with the charger and the power tool body. Each of the charger and the power tool body includes a device memory that stores at least one piece of identification information of a usable battery pack. Each of the charger and the power tool body or the battery pack includes a determination unit that determines whether or not the at least one piece of identification information stored in the device memory includes the identification information stored in the battery pack memory.

Abstract: A motor having a circuit board including at least two MEMS sensors. The circuit board is mounted within a housing of the motor using the same fasteners as an encoder of the motor. Mounting the MEMS sensors to the circuit board simplifies assembly of the motor and standardizes the positioning of the MEMS sensors within the housing, while the overall motor footprint is unaffected.

Abstract: According to an embodiment, a method for compensating instantaneous power failure includes determining whether an input voltage of a plurality of power cells is less than or equal to a first threshold voltage, decreasing, when the input voltage is less than or equal to the first threshold voltage, an output frequency of the inverter, determining whether a voltage of a direct current (DC) link is greater than or equal to a second threshold voltage, and increasing, when the voltage of the DC link is greater than or equal to the second threshold voltage, the output frequency of the inverter. Overvoltage trip may be prevented at the power restoration time and overcurrent trip caused by increase in the slip frequency may be prevented. Thereby, reliability of a medium inverter may be enhanced, and a continuous operation time increased compared to the conventional cases may be ensured.

Abstract: A thyristor starting device includes: a converter which converts AC power supplied from an AC power source into DC power; a DC reactor which smooths a DC current; an inverter which converts the DC power provided from the converter into AC power, and supplies the AC power to a synchronous machine; a gate pulse generation circuit which generates a gate pulse to be provided to thyristors of the converter and the inverter; a control unit which sets a phase control angle of the gate pulse to be provided to the thyristors of the converter, by controlling a current of the converter such that the DC current flowing into the DC reactor matches a current command value; and an abnormality detection unit which compares a detection value of the DC current with the current command value, and determines an abnormality in the gate pulse based on a comparison result.

Abstract: A motor controller coupled to a motor for a pump is described. The motor controller is configured to determine a first mode of operation for the motor, based on at least one of a predefined schedule stored by the motor controller and an input signal received by the motor controller from at least one ancillary device. The motor controller is additionally configured to transmit a first control signal to the motor to operate the motor in the first mode, and to transmit a second control signal to change an operation of the at least one ancillary device, wherein the at least one ancillary device includes one or more of a heater, a chlorine generator, and an ozone generator.

Abstract: A motor starter apparatus includes at least one semiconductor switch configured to selectively couple a power source to a motor, at least one current sensor configured to generate a current sense signal indicative of a current provided via the at least one semiconductor switch, and a control circuit coupled to the at least one current sensor and configured to cause the at least one semiconductor switch to momentarily couple the power source to the motor and identify a fault based on a behavior of the current sense signal in response to the momentary coupling. The control circuit may be configured to identify the fault responsive to detecting that a rate of change of the current in response to the momentary coupling meets a predetermined criterion.
