Abstract: An economical system and method for extracting amplitude and frequency information from a modulated AC signal are provided. In one embodiment, the invention includes a circuitry implementing op amps, a dual diode, a filter, and a comparator to receive and manipulate the modulated AC signal. The dual diode receives and splits the AC signal into two separate paths, including a baseline path and a filtering path. The AC signal passing through the baseline path remains substantially unchanged, and the AC signal passing through the filtering path passes through a low-pass filter. The signal is then sent through a comparator for comparing amplitudes of the AC signal from the two paths, and the comparator output is received by a microprocessor for controlling a display that generates a visual indicia responsive to the comparator output.

Abstract: A lighting system, apparatus and method that can be integrated into an office or household item. The lighting system has one or more light modules, each comprising three lights of a different color. The light modules further have a cover component having a hole positioned above the lights. The lighting system may further have a cushioned layer coupled to the light modules. The light modules are coupled to a power source and an integrated circuit, wherein the integrated circuit is configured to operate the light modules.

Abstract: The present invention is a dispenser adapted to be coupled to a fluid container. The dispenser comprises a dispensing head, an energy source, and a fluid pathway. The dispensing head includes a fluid pump, a motor adapted to power the pump, a trigger adapted to control the motor, and a nozzle orifice in fluid communication with a discharge end of the pump. The fluid pathway has one portion in fluid communication with an intake end of the pump and another portion inside the container.

Abstract: The present invention is a dispenser adapted to couple to a fluid container having an opening surrounded by a neck. The dispenser comprises a cap, a dispensing head, an energy source, and a conduit. The cap is adapted to seal the opening fluid tight when the dispenser is coupled to the container. The dispensing head is pivotably secured to the cap and includes a fluid pump, a motor adapted to power the pump, a trigger adapted to actuate the motor, and a nozzle orifice in fluid communication with a discharge end of the pump. The energy source is electrically connected to the motor and extends inside the container. The conduit has a first end in fluid communication with an intake end of the pump and a second end inside the container.
