Abstract: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: A food dispensing machine includes a product chamber with a dispensing valve connected to the product chamber and having an outlet through which a product contained in the product chamber is dispensed. The product chamber has a cleaning solution inlet connectable to a cleaning solution supply source for receiving cleaning solution into the product chamber. The product chamber further has an ingredient inlet alternatively connectable to either an ingredient supply source or the dispensing valve outlet. When the ingredient inlet is connected to the dispensing valve outlet, a re-circulating flow path is created, allowing for complete cleaning and sanitizing of the product flow path.

Abstract: A toilet odor elimination device and system prevents malodorous toilet odors from escaping into the surrounding air by means of vacuum-like inward flow of air into gasketed toilet where such together with any malodorous are ported out the rearward portion of the toilet into the plumbing vent pipe with assist of vacuum-like pump or motor optimally of sufficient power to maintain lower air pressure within the toilet bowl than its surrounding air pressure.

Abstract: A programmable leak tester is implemented to include the ability for performing a math step in conjunction with the program steps. The math step can use as inputs the result of a previous step, a register value, or a previous compensation or calibration value. As outputs, the math step can provide a compensation or calibration value for use in the execution of another program, can provide a register output, or can be provided as the step result for the current step. By using multiple math steps, the programmable tester provides flexible and adaptable leak testing in a variety of applications.
