Systems and Methods for Monitoring and Controlling Internal Pressure of an Eye or Body Part
ActiveUS20090275924A1Avoiding undesirable loss of pressureAvoid cloggingEye surgeryPharmaceutical delivery mechanismInternal pressureBiomedical engineering
Systems and methods for automatically monitoring and controlling pressure in a body part are disclosed. The systems include an implantable tube with one open end of the tube implanted in the body part, an implantable valve coupled with the tube having at least one open state and a closed state, an implantable sensor for measuring pressure, and an implantable control device coupled with the sensor and the valve. The control device switches the valve between the at least one open state and the closed state, based on pressure information received from the sensor. When the valve is in the at least one open state, the tube drains fluids from the body part due to a difference of pressure between the open ends of the tube. Methods for using the systems to administer drugs and monitor and control fluid pressures in various biological systems are also disclosed.

A condensate pump for an HVAC system includes a reservoir for collecting condensate water, a pump motor connected to an impeller pump for pumping the condensate water out of the reservoir, and a floatless pump control module. The floatless pump's microcontroller detects the water level in the reservoir and, based on the water level in the reservoir, controls the operation of the pump motor, and if necessary, sounds an alarm and shuts down the HVAC system. The floatless pump microcontroller may employ an ultrasonic transducer or capacitance sensors to detect the level of condensate water in the reservoir. The microcontroller implements a variable water lift feature to pump the water using the lowest possible speed for the pump. The microcontroller implements a self-cleaning feature to pump stagnant water out of the reservoir and to pulse water in the drain line and the agitation of the water in the reservoir. The microcontroller implements an anti-clog feature to clear a clogged drain line when an overflow condition is detected.

Hydraulic suction fuse for swimming pools
A hydraulic suction fuse is mounted in a conventional debris collection trap of a swimming pool, spa or the like, to significantly reduce or eliminate any suction force on the bottom or side wall mounted drain of the swimming pool, spa or the like, as a result of the drain becoming essentially wholly covered by a body part of a person or other drain clogging article. Alternatively, the hydraulic suction fuse may be mounted in a compartment in line between the drain and a suction pump of a swimming pool, spa or the like. Thereby, a person captured by the suction force at the drain will be released and the person is free to move away from the drain essentially instantaneously upon contact with the drain. In one embodiment, the hydraulic suction fuse is self resetting once inflow through the drain is no longer restricted. In another embodiment of the hydraulic suction fuse, the hydraulic suction fuse may be easily manually reset.
