A motor assembly includes a control sub-assembly configured to be mounted either remotely or integrally to a motor. The control sub-assembly includes a control housing, a control housing cover, electronic control components, and at least one sensing wire connected to the motor. The control housing cover includes a first attachment portion and a second attachment portion. The first attachment portion attaches the control housing cover to the control housing and the second attachment portion attaches the control housing cover to the motor. If the control sub-assembly is to be mounted remotely from the motor, the second attachment portion is not connected to the motor.

A current regulation circuit for a motor. The motor includes a stationary assembly having windings adapted for energization in at least one preselected sequence and a rotatable assembly in magnetic coupling relation to the stationary assembly. A power supply link connects the windings to a power supply and includes power switching devices for selectively energizing the windings in the preselected sequence by selectively connecting the power supply link to the windings to produce an electromagnetic field for rotating the rotatable assembly. The power switching devices each have a conducting state and a nonconducting state. The current regulation circuit includes a timing circuit, a current sensing circuit and a control circuit. The timing circuit defines preset periods during which each of the power switching devices may be nonconducting. The current sensing circuit senses current in the power supply link. The control circuit controls the power switching devices so that each of the power switching devices is nonconducting when the sensed current exceeds a peak current reference level during the preset periods. In this manner, the current regulation circuit controls current which circulates during periods when only one power switching device is conducting.

An emergency signaling device adapted to attach to an existing flashlight is disclosed. The device provides audio, optical and radio frequency alarms when the device detects no movement for a period of time. The radio frequency alarm is coded so that a plurality of the devices may be used in conjunction with a receiver to form an emergency signaling system. The receiver decodes the signal and indicates which device has transmitted the alarm. The device uses the battery in the flashlight for power. A noxious gas detector may also be integrated into the device.
