摘要:
An assembly for supplying heated air to a housing with an interior that is adapted to hold air conditioning equipment. The housing has a top portion and a back portion, where the top portion defines a first opening that leads to the interior of the housing, and where the first opening is proximate the back of the top portion of the housing. The back portion of the housing defines a second opening that leads to the housing interior, where the second opening is proximate the top of the back portion. The assembly includes a flue external to the housing and adapted to be coupled to the housing such that the flue encompasses and is in fluid communication with the first and second openings, the flue defining an inlet for conducting heated air into the flue and an outlet for conducting heated air out of the flue and into the housing through the first and second openings. The air cooled by the air conditioning equipment in the housing is used to cool electronic equipment.

The invention combines systems and methods for heat containment and cold air isolation for managing airflow and temperature in data centers. The data center contains at least two rows of cabinets containing heat-generating equipment and arranged to form a cold aisle and a hot aisle. The data center system includes panels or doors at both ends of the cold aisle and an optional cover over the cold aisle to inhibit cooled air supplied by an air conditioning system from exiting the cold aisle and inhibit air warmed by the heat-generating components from entering the cold aisle. A chimney coupled to the top, rear, or top and rear of the cabinets is configured to exhaust the warmed air into a region above the rows of cabinets. The chimneys may be ducted to a plenum or suspended ceiling or to the intake of the air conditioning system. Baffles and/or fans may be included in the chimneys, ducts, and/or plenums to control the air pressure. The invention may also include one or more data center air conditioning units, and each air conditioning unit may be configured to service one or more rows of cabinets. Alternatively, or in addition, cool air may be supplied by the building's air conditioning system.

The invention provides a modular, configurable aisle isolation and containment system that may function as a hot aisle or as a cold aisle. The data center air routing system of the invention comprises one or more free-standing, essentially identical, modular system units. Each modular unit comprises two sidewalls, a ceiling, and a door or panel at either end to form an interior, enclosed aisle. Two or modular units may be coupled together end-to-end. Each modular unit further comprises one or more sidewall blanking panels that may be removed to create gaps of varying height and width to accommodate one or more IT racks. Each modular unit may also include one or more ceiling-mounted air ducts, baffles and fans to manage air flow.

A proximity fuzing arrangement for fuzing warheads carried by missiles which reduces the likelihood of the missile being detonated prematurely by such cases as rain or enemy counter measures. The fuzing arrangement includes at least two channels responsive to target signals in different frequency bands and also includes means for comparing the signals in these channels to distinguish between spurious signals such as enemy counter measures or rain and so called “true target signals”.

An implantable programmable drug delivery system for injection of a pharmaceutical agent into the peritoneum to treat cardiac arrhythmia is described. The device consists of essentially three components: a main body containing electronics, power supply, valve means, and drug reservoir; an electronic lead into the heart to transmit impulses from the heart and deliver electronic responses to the heart; and a separate specialized drug delivery catheter for delivery of agents to the peritoneal cavity or near the exterior of the pericardium.
