Abstract: A system and method to control the cleaning and emptying of a wastewater holding tank on a Recreational Vehicle. The system has the ability to autonomously open the drain valve allowing the tank to be emptied while connected to a suitable drain hose. It also has the ability to automatically rinse the tank from an external water source—should the system be so equipped. Further, the system and method can operate a wastewater system with two or more tanks each tank having its own gate valve used to empty the tank. In, this configuration the system will only open one gate valve at a time.

Abstract: A blasting cap simulator for use in bomb disposal training. The simulator has a bridge rectifier, a voltage regulator and an RF key fob transmitter. A fuse across the incoming power lines shorts the device and prevents it from activating until the fuse is blown. It then sends an RF signal to an instructor. The transmitter uses the power lines as an antenna to send out the RF signal. The transmitter is protected from the voltage of the power lines by a choke located on each powerline.

Abstract: A system and method for detecting the presence of a skimmer in the credit card reader of a kiosk such as a gas pump, ATM or other self-service vending machine which conducts the transaction directly with the consumer without interaction of an attendant or clerk. A light source and a light sensor are located on either side of a card slot on the credit card reader. When the light source is blocked from the light sensor for a predetermined length of time, an alarm is triggered. The alarm may notify an attendant or security to investigate any issues with the credit card reader. The light source is pulsed on and off at a predetermined frequency to differentiate it from ambient light and other light sources.

Abstract: A method for controlling the operation of a vacuum material handler providing secure communication between the wireless remote control and the receiver of a controller on the vacuum material handler. The method providing a haptic confirmation of a valid command. The method also providing a battery life extending sleep mode when left inactive for a predetermined length of time. The method further including a pendant remote in communication with the wireless remote control. The pendant remote being operable to command the vacuum material handler.
