Latest Patents

David K Lee holds a patent for a vacuum cleaner control system. This system utilizes a single pair of conductors to transmit electrical power to a remote motor-driven agitator while selectively energizing the blower motor of the cleaner. The design incorporates photoelectric means to sense current flow in the conductors, triggering the power switch for the blower in response to this flow. Additionally, a switch includes a load capacitor that can be connected between the conductors to establish current flow without activating the remote motor-driven agitator. In one embodiment, the power supply for the agitator motor is separate from that of the blower, with a sensor provided to detect power supply to the agitator and activate the blower accordingly.
