Abstract: A method is provided for controlling a heating, ventilation, and air conditioning (HVAC) system. The method includes measuring a temperature and controlling a compressor of the HVAC system. The temperature is measured by a temperature sensor located between a metering device of the HVAC system and an evaporator coil of the HVAC system. The temperature is representative of a refrigerant temperature. The refrigerant temperature is a temperature of a refrigerant fluid flowing from the metering device to the evaporator coil. The compressor is controlled by control circuitry that is configured to perform the controlling in a dehumidify mode based, at least in part, on a value of a humidity parameter of air of an airflow through an evaporator coil and a reheat coil, where the value is determined using the temperature.

Abstract: Provided is a medical device comprising an inner tubular member, an outer tubular member having a distal end and an open window disposed at the distal end, a first electrode and/or a second electrode disposed at the distal end of the outer tubular member, and a cannulated plunger or armature or shaft configured to drive the inner tubular member to cut tissue in cooperation with the open window of the outer tubular member. The first electrode and the second electrode may be configured to provide RF energy needed for a surgical operation and may be configured to be substantially symmetrical or asymmetrical along a longitudinal axis of the outer tubular member.

Abstract: Provided is a power pack comprising an AC power connector configured to be connectable to an outside AC power source; a rectification and filtering unit configured to be in electronic communication with the AC power connector; a controlling unit; and a medical device connector configured to be connectable to a medical device, the medical device connector configured to be in electronic communication with the controlling unit, wherein the power pack is configured to be capable of detecting a connection of the medical device with the power pack and also capable of demonstrating the connection through an outside indicator disposed on the exterior of the power pack once the medical device is connected to the power pack through the medical device connector.
