Abstract: A wireless sensor unit detects an out-of-range condition of an air filter in a HVAC system by sensing the air flow passing across the filter or by pressure differential across the air filter. A The sensor unit sends a signal to a receiver unit that can be positioned a distance from the sensor unit to process the signal sent by the sensor unit and provide audio and/or visual warning of the air filter condition.

Abstract: A warning for identifying clogged air filter condition uses a sensor mounted in the air passage downstream of the air filter. The sensor is connected to an electrical power generator, which transmits the electrical power to a selected one of the light emitting or audio signal emitting members in response to the decrease in the air flow passing across the air filter.

Abstract: A mounting assembly for a discharge conduit of a medical treatment device, such as a dialysis machine. The mounting assembly has a connector member detachably engageable with a discharge nozzle of a discharge conduit and a suction cup that can be mounted on a rim of a waste receptor, such as a sink or a toilet bow. The mounting assembly supports the discharge nozzle directly above the opening of the waste receptor, thereby facilitating discharge of the liquid waste directly into a municipal sewage line.

The mounting assembly has a connector member detachably engageable with a discharge nozzle of a discharge conduit and a suction cup that can be mounted on a rim of a waste receptor, such as a sink or a toilet bow. To ensure proper orientation of the discharge outlet above an opening of a waste receptor, the mounting assembly provides for a rigid securing clamp that engages the discharge nozzle and hooks to a rim, or under a rim of the waste receptor. The mounting assembly supports the discharge nozzle directly above the opening of the waste receptor, thereby facilitating discharge of the liquid waste directly into a municipal sewage line.
