Abstract: A drug delivery device for delivering a medicament includes a housing, a pump, drive component, an inlet fluid path, an outlet fluid path, an inlet pressure sensor, an outlet pressure sensor, and a controller. The pump is coupled with the housing. The drive component is for driving the pump. The inlet fluid path is configured to deliver medicament to the pump. The outlet fluid path is configured to receive medicament from the pump. The inlet pressure sensor is positioned along the inlet fluid path and configured to measure inlet fluid pressure. The outlet pressure sensor is positioned along the outlet fluid path and configured to measure outlet fluid pressure. The controller is workingly coupled with the inlet pressure sensor, the outlet pressure sensor, and the drive component, wherein the controller is configured to adjust at least one parameter of the drive component based on input information received from the inlet pressure sensor and/or the outlet pressure sensor.

Abstract: A fabric dryer employs microwave energy and an auxiliary air convection heater to heat the moisture in the fabric to be dried and provides for control of the microwave energy so that no arcing of metal or other electrically conductive parts occurs as the fabric becomes dryer. The fabric dryer has a controller that receives input from sensors and uses that input to progressively decrease the energy output from the magnetrons in such a manner to prevent arcing of all metal and other electrically conductive materials associated with the fabric, while also controlling the auxiliary air convection heater and an exhaust air recirculator to compensate for the decreased magnetron energy output.

Abstract: A fabric drying system has an exterior housing and a rotating chamber for containing fabric laden with moisture that is to be dried and uses a combination of microwave energy and an auxiliary convection air heater to heat and vaporize the moisture and expel it with exhaust air so as to dry the fabric. In addition, the fabric drying system employs energy efficiency devices that permit the system to dry the fabric using the least amount of energy. Heat energy from the exhaust air is transferred to the intake in a heat exchanger. Additionally, heat energy from the exhaust air is used by recirculating a portion of the exhaust air and mixing it with the intake air before the air is introduced into the fabric drying chamber. The system also provides for sensors that detect the temperature and/or humidity of the exhaust and the intake air.
