Abstract: System and method for monitoring a working status of a swimming pool cover assembly. The system comprises a pool cover assembly operably connected to an alarm apparatus; both may be operably connected to a plurality of sensors capable of detecting a working status of the pool cover assembly and sending a signal to the alarm apparatus. The alarm apparatus continually produces at least one humanly perceptible indication corresponding to a working status of the pool cover assembly. The alarm apparatus includes at least one alarm-producing device, such as an audio or visual device, or combination of the two, a receiver operably connected to the plurality of sensors for receiving the signals, a processor operably coupled with the receiver for processing and recognizing the received signals, and software operably coupled with the processor enabling the alarm-producing device to produce the humanly perceptible indication corresponding to the recognized signal.

Abstract: A pool cover driving system for rolling up and unrolling a pool cover encased in a protective sealed case but easily attached and detached from a power controller without breaking the seal. A method of installing the pool cover driving system wherein pool cover driving system remains in a sealed state throughout installation process. A method of replacing the pool cover driving system wherein multiple pool cover driving systems each remain in a sealed state throughout process of removal of one pool cover driving system and replacement with another pool cover driving system. A method of operating the pool cover driving system where, in addition to connection to an electrical power controller, electrical input to pool cover driving system is controlled. A method of assembling the pool cover driving system wherein potting compound provides a sealed case by substantially occupying all of interior of case besides electrical motor.

Abstract: The present invention provides a system and a method for monitoring a working status such as detecting a fault condition of a pool cover assembly for a swimming pool. The system comprises a pool cover assembly and an alarm apparatus operably connected to the pool cover assembly. The alarm apparatus continuously produces at least one humanly perceptible indication corresponding to a working status of the pool cover assembly. The system may include a key switch operably connected to the pool cover assembly for turning on and shutting off the pool cover assembly. A plurality of sensors operably connected to the alarm apparatus and the pool cover assembly may be provided. Each of the plurality of sensors is capable of detecting a working status of the pool cover assembly, producing a signal corresponding to the working status, and sending the signal to the alarm apparatus.
