An air conditioning cooling apparatus and method which includes the steps of supplying cooling air generated from a cooling apparatus into an air passageway formed below a floor; guiding the cooling air within the air passageway into an equipment assembly disposed on the floor through an opening located in the floor; communicating the cooling air introduced into the equipment assembly into a plenum and introducing the air released from within the equipment into the plenum and communicating the released air through the cooling apparatus for cooling the released air. The method permits temperature differential between the air supplied to the air passageway and the air introduced into the plenum from the equipment assembly to be 45.degree. F. to substantially 40.degree. F. so as to reduce the power necessary for operating on the fan of the blowing apparatus. The equipment assembly utilizes an air flow control mechanism so as to substantially evenly distribute cooling air to the equipment.

The invention provides a channeling preventing and plugging agent and a construction method for controlling plugging and sealing channeling by utilizing the channeling preventing and plugging agent. The channeling preventing and plugging agent comprises a high-temperature-resistance pre-plugging agent serving as a pre-posed pre-plugging plug, an enhanced gel plugging agent serving as an intermediate enhanced plug and a high-strength resin plugging agent serving as a postposed sealing plug. The channeling preventing and plugging agent has the characteristics of high temperature resistance, long-term stability, good plugging performance and the like. The invention further provides a construction method for controlling plugging and sealing channeling by utilizing the channeling preventing and plugging agent. The method has a simple constructing process, and can be used for constructing after the channeling preventing and plugging agent is directly prepared on the spot. The channeling preventing and plugging agent can be used for effectively solving the adverse impact of the steam/air channeling phenomenon of a heavy oil thermal production well on production, and has an important effect on prolonging the production cycle of a heavy oil well and improving the recovery efficiency.

Apparatus and method embedding a camera in a street light includes structure and/or function whereby the street light, comprising has a first compartment having an LED array configured to illuminate an area beneath the street light. A second compartment is coupled to the first compartment and has a camera directed toward the area beneath the street light. The second compartment has a window covering the camera such that the camera can receive light from area beneath the street light, but passers-by do not see the camera. A third compartment is coupled to the second compartment and is configured to attach the street light to a vertical support. A passive air channel is disposed between the first compartment and the second compartment, and is configured to direct air from beneath the street light to the top of the street light. Preferably, the power supply for the LED array is disposed in a compartment different that the first compartment. An anti-glare device is preferably mounted to a bottom of at least one of the first compartment and the second compartment, and is configured to shield the camera from light glare and/or reflections from the LED array.

A method for reading and tracking radio frequency identification (RFID) tags in the presence of a noisy air channel is provided. In accordance with the method, a binary tree data structure is used to characterize a plurality of RFID tags, each of which is associated with a unique identification (ID) number. During communication between a tag reader and one or more RFID tags, the tag reader traverses the binary tree, eliminating tags from communication until one tag with a unique ID number is isolated and verified. As the binary tree is traversed, counters associated with each node in the tree are incremented based on tag matches, such that, over time, counters associated with nodes in tag-populated branches will tend to have a high value and counters associated with nodes in unpopulated tree branches will tend to have low values. Where the read process is subject to noise and the tag reader is forced make a decision at a branching node, the tag reader makes a branch prediction based on the current value of the node counters associated with each of the possible alternative branches.

The invention relates to an air buffer having an automatic seal body air shutting-off and locking device and a making method thereof. The air buffer comprises a seal body composed of a continuous film coil and comprising two pieces of external film and two pieces of internal film, a plurality of equidistant heat-resistant nodes made from heat-resistant material are coated on the top of the internal surface of one internal film, and hot seal nodes are arranged at the positions at the same height as the heat-resistant nodes of one external film, and hot seal transversal lines are employed to divide the seal body into aerating channel regions and air storing columns, the aerating channels join the air storing columns through the hot seal lines, an internal film with heat-resistant nodes is arranged on the external film to make the internal film and the external film unjoined to form a sole channel air inlet. When aerating, the air channel portions of the two pieces of external films will expand to draw the internal films joined therewith, thus to allow all the air inlets along the air channels to open indirectly. In this way, a plurality of seal bodies are needed to be aerated, the air inlets are shut off and the air inlet paths are locked after aerating, thereby the air buffer having dual air shutting-off functions and durable seal performance.

A high speed connector includes a plurality of wafer-style components in which two columns of conductive terminals are supported in an insulative support body, the body including an internal cavity disposed between the two columns of conductive terminals. The terminals are arranged in horizontal pairs, and the internal cavity defines an air channel between each horizontal pair of terminals arranged in the two columns of terminals. The terminals are further aligned with each other in each row so that horizontal faces of the terminals in the two rows face each other to thereby promote broadside coupling between horizontal pairs of terminals. A dielectric insert is provided between the columns of terminals to thereby influence the broadside coupling between pairs of terminals.

As to a heat sink manufacturing method of a plasma display apparatus according to the present invention and the manufacturing device, a widthwise direction air channel and a lengthwise direction air channel are formed through a extrusion and a rolling processing to facilitate a processing with a continuous extrusion and rolling processing. Accordingly, the productivity is notably improved.

A three-dimensional (3D) chip stack structure and method of fabricating the structure thereof are provided. The 3D chip stack structure includes a plurality of vertically stacked chips which are interconnected and bonded together, wherein each of the vertically stacked chips include one or more IC device strata. The 3D chip stack structure further includes an air channel interconnect network embedded within the chip stack structure, and wherein the air channel interconnect network is formed in between at least two wafers bonded to each other of the vertically stacked wafers and in between at least two bonded wafers of the vertically stacked wafers at a bonding interface thereof. In addition, the 3D chip stack structure further includes one or more openings in a peripheral region of the chip stack structure that lead into and out of the air channel interconnect network, so that air can flow into and out of the air channel interconnect network through the one or more openings to remove heat from the chip stack structure.

An adapter for attaching to an earphone includes a sleeve capable attaching the adapter to the earphone and an ear portion including a tubular sidewall having a first end attached to the sleeve and a second end opposite the first end.
