Abstract: A Voice over Internet Protocol (VoIP) proxy server is described. The VoIP proxy server is placed in a DMZ of a company's secure internal communication network. The VoIP proxy server receives VoIP control messages and VoIP media streams and based on the MAC address and source IP address contained in the control message, pushes a policy change to the internal network's external firewall to open call control protocol ports and Real Time Protocol (RTP) ports only for packets from the source IP address. The VoIP proxy server manages the hiding of the company's internal network address and directs incoming VoIP packets to an IP-PBX connected to the company's internal network.

Abstract: Provided is an aquifer replenishing pavement formed above soil having a sand lens above the aquifer and a clay layer above the sand lens. The pavement includes an aggregate leach field having an aggregate top surface, and an aggregate bottom surface abutting the clay layer. The pavement further includes a pavement layer having an exposed pavement top surface, and a pavement bottom surface abutting the aggregate leach field. A surface drain extends through the pavement layer to drain fluid from the exposed pavement top surface to the aggregate leach field. An aggregate drain extends from the aggregate leach field into the sand lens through the clay layer to drain fluid from the aggregate leach field into the aquifer. A filter is disposed within one of the surface drain and the aggregate drain. The filter is configured to remove foreign particulates from fluid passing therethrough.

Abstract: An improved surface seeded exposed particulate concrete and method of making the improved surface seeded exposed particulate concrete is disclosed. Small particulate is sprayed over the upper surface of the concrete. The particulate may be sprayed using a material sprayer. The particulate may be uniformly sprayed to distances exceeding twenty feet. The particulate is mixed into a cement paste derived from the concrete mixture using floats. A surface retarder is then applied to cover the concrete surface. Subsequently, any surface film is washed from the surface of the concrete and the concrete is cured. The result is a surface seeded particulate with an exposed surface that is flat and is suitable for high traffic areas. The resultant surface may resemble stone, granite or marble.

Abstract: Disclosed are a concrete dowel placement devices and a method of utilizing the same. A metallic stud is driven, screwed, or otherwise attached to a form. The stud may be a unitary structure, or may be a hollow tube with conventional fastening means such as nails and screws extending through and holding the hollow tube to the form. A cover having an interior compartment substantially equal in diameter to the stud is slidably placed thereon, and a first enclosed area is developed with a plurality of forms. Concrete is poured into the first enclosed area, and upon curing, the form and the stud are removed, leaving the cover embedded in the concrete. A metallic dowel is inserted into the cover, and a second enclosed area is developed with like configured forms. The metallic dowel extends into the second enclosed area.

Abstract: A method of transferring a design to an uncured concrete surface of a poured concrete mixture is provided. The method comprises the steps of: (a) placing a releasable template onto the surface to define exposed and covered regions; (b) manipulating the exposed regions corresponding to the design; (c) removing the template to reveal the covered regions; and (d) finishing the surface. The template may be variously configured and may incorporate positive and negative portions, which may be alternatively utilized to transfer the design to respective positive and negative regions of the surface. The template may preferably be fabricated from visquene, craft paper, or other suitable material. In addition, implementations of the present invention may be utilized with surface seeded exposed aggregate, troweling, or other surface finishing processes.

Abstract: A non-slick surface-seeded exposed aggregate concrete product and method of making the same enhances the coefficient of friction of an exposed surface thereof to reduce undesirable slipping and sliding. Implementations of the present invention are characterized by the use of fine sand and aggregate broadcast over the exposed surface, which surface has been prepared to receive the same. After curing, the exposed surface is then ground and acid-etched to define fissures, cracks, and/or sharp edges of the aggregate. Subsequently finishing steps are performed to produce the non-slick concrete product which may be used for high traffic pedestrian areas where foot gripping and traction are important, such as on stairs, ramps, walkways, courtyards, and the like.

Abstract: A keyboard system which includes a keyboard assembly and an embedded controller. The keyboard assembly includes a keyboard matrix and a keyscan controller coupled to the keyscan matrix. The keyscan controller receives position information from a pressed key of the keyboard matrix and generates basic keyscan information. The embedded controller receives the basic keyscan information and generates keycodes based upon the basic keyscan information.

Abstract: A mosaic concrete product, methods of creating the same, and methods of fabricating a module for use in creating the mosaic are provided. The methods of installing the mosaic upon an uncured concrete surface utilize the module. The module may be fabricated by mapping out tile in a design corresponding to the mosaic; adhering the tile to a template utilizing an adhesive, the tile being positioned thereon corresponding to the design; and allowing the adhesive to set. The module may define upper and lower surfaces, the upper surface including the tile adhered thereto. The methods of installing the mosaic comprises: positioning the module upon the uncured concrete surface; embedding the tile into the concrete surface; massaging the tile into the concrete surface to interpose a quantity of cement/fines paste between the adjacent tiles; and finishing the concrete surface.
