摘要： An immersion sensor for use with a cushion or mattress for determining the relative immersion of a person within the cushion or mattress comprising a sensor, a ground and a circuit for measuring capacitance. The sensor comprises a sheet of conductive material, and the ground comprises a second sheet of conductive material. The circuit is adapted to send short bursts of electrical current to the sensor and a capacitor. The circuit is further adapted to measure the length of time the burst of current takes to charge the capacitor. Based upon the measured time, the circuit calculates the proximity of the object based upon the time taken to charge the capacitor. A method that may be implemented with the immersion sensor is also disclosed.

摘要： A vacuum control system allows the vacuum to be turned on and off automatically based on the operation of an associated power tool. The vacuum is able to run at full power without sacrificing power to the power tool itself. Additionally, a pneumatic power tool may be used to control the operation of the vacuum.

摘要： A sensor for attachment to an inflatable air cell cushion to detect a change in immersion depth and bottoming out of the user seated on the cushion. The sensor includes an airflow conduit for attachment to the cushion inflation tube. The airflow conduit comprises a cylindrical body having a longitudinal inner bore. There is an opening through the conduit body in fluid communication with the bore. A transducer is positioned at the opening to detect changes in air pressure within the airflow conduit. The transducer is operatively connected to a warning light, an audible sensor and a mode set button. The functions of the electronic components are preprogrammed into a computer chip. A battery powers the sensor. The recited components are secured within a housing.
