A system and computer-implemented method for controlling wireless access to the operations of communicative electric motors. An electronic processing element receives an authentication request from a remote access device via a wireless transceiver, approves the authentication request, including determining an associated access level from among a hierarchy of access levels, and grants access to a motor controller to perform actions allowed by the associated access level. Approving the request may be based on receiving a valid password, which may be calculated on the remote access device by a computer program using an electronic key, or by receiving information from an authentication hardware component associated with the device. The various access levels may allow for shutting off, read-only monitoring (of, e.g., temperature, vibration), controlling (e.g., speed), and programming (e.g., tap settings) operation of the motor, and controlling the authentication process (e.g., adding and removing users and assigning and changing access levels).

A system and computer-implemented method for improving controlling the operation of an alternating current electric motor using programmable multiplexed tap input logic. Programmed bit patterns and corresponding tap numbers are stored in a look-up table in a non-volatile electronic read-write memory element. Input channels are monitored for tap input signals, and an input bit pattern is formed based on the tap input signals. The input bit pattern is compared to the programmed bit patterns, and if the input bit pattern matches a particular programmed bit pattern, then a control signal is transmitted to activate the particular tap number which corresponds to the particular programmed bit pattern, thereby controlling the operation of the motor. If there is no active tap, then the motor is turned off. The programmed bit patterns and/or the corresponding tap numbers may be changed by writing to the look-up table in the non-volatile electronic read-write memory element.

System and computer-implemented method for controlling motor operation using programmable multiplexed tap logic

An apparatus for selectively enabling power including a power supply, and a device having a controller and an input activated by a user. The controller is selectively powered by the power supply. While the device is in a sleep state, a sensing circuit senses activation of the input by the user and enables the power supply to provide power to the controller in response to the sensed activation of the input by the user. A latch circuit causes the power supply to continue to provide power to the controller. The controller is responsive to the sensed activation of the input by the user for enabling the latch circuit and for disabling the latch circuit, thereby reentering the device into a sleep state.
