The invention discloses a data behavior based low-energy consumption cluster storage replication device and method. The data behavior based low-energy consumption cluster storage replication device comprises a metadata server and a storage server. The storage server is composed of a hot node set and a cold node set. The data behavior based low-energy consumption cluster storage replication method includes that the hot node set is in a normally open state to store hot spot data frequently accessed by clients and provides QoS (quality of service) guarantee for a storage system; the cold node set stores cold spot data containing large amount of data and seldom accessed by the clients, automatically transfers into a dormant state in the absence of requests, and immediately switches back to a working state to process requests once arriving. Since data access behaviors of the clients are subject to a 80/20 rule, that is, 80% of the requests concentrate on 20% of the hot spot data, while only 20% of the requests access to 80% of the cold spot data. By the method, energy consumption of a system can be greatly reduced on condition that the quality of service of storage cluster system performance is guaranteed.

A heating, ventilation, and air conditioning (HVAC) system includes a network of wireless remote climate sensors to develop a complete heat map of an enclosed space. The remote climate sensor is configured to collect temperature and humidity data on a zone of the enclosed space. The HVAC system uses a network of these sensors to obtain data points across the enclosed space. The resulting heat map is used by the HVAC system to determine where to direct air in the enclosed space. By comparing the temperature and humidity at a specific remote climate sensor with the user's desired temperature and humidity, the HVAC system can decide whether to increase or decrease the air flow through a variable damper that is located near the remote climate sensor. By conducting this analysis throughout the enclosed space and making incremental adjustments to the air flow in hot and cold spots in the enclosed space, the disclosed HVAC system provides even comfort to the user along with reduced energy consumption.

A warming gas flows through a jacket to heat an insufflation gas flowing in a separate tube, thereby reducing cost and disposable waste. The heated warming gas may be filtered to sterilize or maintain sterility and released to atmosphere after heating the flowing insufflation gas. Alternatively the warming gas may be reheated and recirculated through the jacket, with an additional tube being used within the jacket so that the warming gas flows in both directions lengthwise. The insufflation gas may be carbon dioxide and the warming gas may be room air. The heating element and sensors may be separate from the disposable unit of a heated insufflation set, and need not be re-sterilized prior to or after use in surgery. The heat is constantly maintained, thereby eliminating “cold spots” caused by the natural cycling of the resistance heaters due to the nature of the operation being preformed on the patient.

A single-ended arc discharge vessel for a metal halide lamp includes a U-shaped arc discharge chamber that has two juxtaposed subchambers with a divider wall therebetween and a passageway around the divider wall that connects the two subchambers to each other. The vessel has two parallel electrodes in a same end of the vessel that is opposite the passageway. Each of the electrodes extends into a respective one of the two subchambers a distance less than a height of the divider wall so that the arc discharge between the electrodes is U-shaped. This arrangement moves the vessel cold spot away from the electrodes to permit higher operating temperatures and increases arc gap length for a given vessel size to permit a higher lamp voltage.
