A system arid method for enabling highly scalable multi-node event distribution networks through the use of summary-based routing, particularly event distribution networks using a content-based publish / subscribe model to distribute information. By allowing event routers to use imprecise summaries of the subscriptions hosted by matcher nodes, an event router can eliminate itself as a bottleneck thus improving overall event distribution network throughput even though the use of imprecise summaries results in some false positive event traffic. False positive event traffic is reduced by using a filter set partitioning that provides for good subscription set locality at each matcher node, while at the same time avoiding overloading any one matcher node. Good subscription set locality is maintained by routing new subscriptions to a matcher node with a subscription summary that best covers the new subscription. Where event space partitioning is desirable, an over-partitioning scheme is described that enables load balancing without repartitioning.

A slatwall extrusion and assembly for a wall of a building to support hangers and shelving and the items they carry. Each section of slatwall has a continuous linear rear wall that integrally joins number of spaced boards. Each board has front, rear, top and bottom walls that form a continuous loop around a hollow interior. Each board also has a downwardly extending double-walled lip. The lip is spaced from its adjacent lower board to form an L-shaped slot. The continuous rear wall is firmly secured to the studs or drywall of the wall by self tapping screws or an adhesive coating. The linear rear wall, hoop shaped boards, and double-walled lips combine to form a sturdy, lightweight and inexpensive slatwall extrusion. High impact polystyrene (HIPS) is used to achieve even further cost and weight reductions while maintaining the strength of the slatwall extrusion and assembly.

A method and apparatus for adding rigidity and weight to the piping used in geothermal wells for ground-source heat pumps enhances insertion of the piping into the wells. The weight used must be approved by appropriate organizations such as the DNR, NSF, and / or EPA, or similar, for contact with the ground water. Concrete and coated iron or steel are examples of such weights. A system for assembling the pipes, weight, and a tremie pipe for insertion is disclosed. The weighting system may also help maintain straightness in the geothermal piping for ease of inserting the piping into the vertical well.

The invention discloses a vehicle diverging traffic light and application thereof. The invention belongs to the traffic control field. According to the technical proposal of the invention, a first basic structure of the traffic light consists of a strip-shaped light, an arrowhead light and a dish-shaped light, wherein, four light bodies are manufactured to constitute a main light body for turningaround, turning left, driving straight ahead and turning right. A second basic structure is that the arrowhead light is manufactured into two light bodies for turning left and driving straight ahead.A third basic structure consists of a human-shaped light, a vehicle-shaped light, a left light and a right light, wherein, a walking and pushing vehicle and two front light bodies constitute an auxiliary light body. The lights are controlled by switches and six basic signal sources can be provided, thus forming a whole or separate vehicle diverging traffic light. The application signal of the traffic light can classify, diverge and control vehicles at intersections of urban highway through signals. The vehicles can be forced to diverge at peaks; divergence of vehicles can be controlled in a normal period; the vehicles drive naturally in a depressed period. In addition, the invention provides a novel signal option for intelligent or remote control of divergence and passing of vehicles, thus improving the passing security and capability of road intersections.

A brushless DC motor including a stator having plural slots; and a rotor which has plural permanent magnets and is divided into three rotor blocks in a rotation axis direction, the three rotor blocks being layered so that the arrangement angles of the rotor blocks differ from each other by an amount of a mechanical angle in a rotary direction that is equivalent to one third of a pulsation period of cogging torque generated by the rotor and stator. A brushless DC motor including a rotor having plural magnetic poles provided at an equal pitch in a circumferential direction by mounting permanent magnets in magnet mounting holes; and a stator having plural slots arranged at an equal pitch in a circumferential direction. The magnetic poles of the rotor include magnetic poles whose magnet deviation angle formed by the central line of an effective polar opening angle and the central line of the magnet mounting hole is the first angle; and magnetic poles whose magnet deviation angle is the second angle different from the first angle.

A bag for a pant pocket according to the present invention further includes an intermediate pocket that is disposed between the first sheet and the second sheet, with the edge attached throughout the entire section to the second sheet and has at least two or more internal inlets formed in the shape of a through-hole though both sides so that going in and out of an internal space formed by the attachment is possible, in which an internal pocket separate line for attaching the second sheet and the intermediate sheet in the structure of separating the areas including two or more internal inlets, respectively is provided, the edge except the partial section of the first sheet is attached to the intermediate sheet to form the main inlet, and the receiving spaces are more easily used by providing at least two or more separate specific internal pocket spaces in one pocket.
