Abstract: A method is afforded for utilizing and implementing a hub and probe system in a wireless communication structure. A hub communicates a first signal. The signal is communicated via evanescent waves created by an exciter. A probe receives the signal from the exciter via the evanescent waves. Conductive elements included in walls of the wireless communications structure receive a second signal from the probe. The conductive elements communicate the second signal to the exciter. The exciter passes the second signal back to the exciter.

Abstract: Method of high-strength sandwich skin fabrication uses the thickness of a high-density foam skin core (27) to mask minor imperfections on the surface of the mold (10,20), thereby allowing the mold to be divided into separate integral parts that have the capacity to be moved, then fixed and set, so as to describe different curves or modify dimensions of the board. Mold is reversible; male/female configurations permit fabrication of a wide array of custom designs. Method offers low production costs due to a rapid mold cycle, reduced labor, and efficient use of space, yet produces an exceptionally high strength, light weight board because of the increased shear strength of the monocoque perimeter rail (70), and the optimum fiber/resin ratio in the cored, structural sandwich skin.

Abstract: An exciter system (1, 2) able to communicate information between an exciter unit (10) and one or more remote units (12) or between multiple exciter units (10). The exciter units (10) may include wireless type exciter devices, such as optimum exciters (14), or they may include wired equivalent type exciter devices, such as direct connect exciters (16). The exciter devices (14, 16) inject or extract RF currents (24) in the metallic framework (22) of a vehicle. The remote units (12) couple electromagnetic fields (26) with the metallic framework (22) of the vehicle. The information is exchanged with the exciter devices (14, 16) by communications equipment (20) that modulates or demodulates the RF currents (24) and/or electromagnetic fields (26) with the information. As the RF currents (24) and/or electromagnetic fields (26) reach everywhere within, on and in close proximity to the vehicle the information is communicated throughout.

As the pen type scanner (10) is moved across the page (76) a roller (34) activates a distance encoder (32). The pen type scanner (10) is connected to a parallel port (54) of a computer (56) through an interconnection cable (50) and a port adaptor component (58).

The system 10 includes an illumination system 27, a material supply system 60 having a nutrient supply 72 and a water supply 70. The system 10 also includes a root chamber 50, a retractor assembly 46 for controllably retracting a lower portion of the plant stems 56 into the root chamber 50, a harvesting assembly 102 and a controller 100 which directs the actions of the included systems and assemblies. The system 10 is provided with a variable speed fan 26 to aid in produce harvesting and self-pollination, and a gravity compensator 114 for preventing water vapor accumulation in stagnant areas.

Abstract: A tent pole base bracket (10) having at its outer end (18) a termination hook (24) for receiving attachment of common tent options like canopies, tarpaulins, and rain flies. The preferred form of the bracket (10) has a pass through slot (30) located at its inner end (20) for accepting a web strap from a tent wall, which may be permanently or temporarily attached to the bracket (10). Roughly central to the bracket (10) a pole orifice (34) is provided for receiving the end of a tent pole. The bracket (10) may have a base curved shape (38) to permit it to rock into a position that optimally handles stresses received concurrently from tent wall fabric, a tent pole, and an attached canopy. Further, the bracket (10) may be constructed so that a defined pole axis (40) and a defined hook axis (42) may be substantially parallel in use of the bracket (10).

Abstract: A hand-held water injecting tool (10) provides for the admixture of water to cementitious materials. The tool (10) is generally comprised of a water-conveying tubular body (12), and a blade assembly (16) having a tip (17). The tubular body (12) has a circuitous configuration to afford both a built-in, ergonomic handle portion (35) and a capacity to perform mixing operations within relatively high-walled containers. At a water-emitting end (20) are present a pair of nozzles (52) which are integrally fashioned from the tubular body (12) to impart jet action to the emitted water. The blade assembly (16) includes a generally triangularly shaped blade (62) attached to the second end (20) such that the water is emitted from the nozzles (52) at a location proximate and external to the blade tip (17) so that the force of the fluid is used in close conjunction with mechanical action of the blade.

Abstract: An adjustable pressure mount heatsink subassembly (10) is provided for use with an electronic chip component (16). The system (10) includes a heatsink portion (12) having a block (28) which has a formed thereon to extend the lateral dimension of the circuit board portion (20) of the chip component (16). A mounting subassembly (14) is, in the preferred embodiment, disposed substantially within the transverse channel (34) and includes a spring clip (40) having a threaded aperture (44) centrally located in a pretensioned arc portion (46) and a pair of opposed end portions (48) for engaging the circuit board portion board edges (26). The pressure of attachment is adjusted by a threaded screw (42) which extends through the threaded aperture (44) and engages the channel floor (36) of the heatsink block (28). An optional nonconductive coating (52) is provided on the clip ends (48) in order to prevent unintended electrical conductance.

Abstract: A screw extruder (10), including a barrel (18) having a bore (26) which defines an inner surface (24). At least one extruder screw (28) is positioned within the bore (26), each screw (28) further including a central shaft (34) and at least one screw flight (30). Each screw flight (30) further includes a front pushing face (36) and a rear face (38). The profile (40) of each front pushing face (36) acts with the inner surface (24) of the barrel (18) to form a progressively narrowing passage (46) through which material is forced into multiple regions of high elongational and shear stress (48) which act to break down agglomerates of material and thus dispersively mix the material.Also presented is a screw extruder (100) having a single screw (28) which includes dispersion disks (102) which are rotationally offset from one another and whose design is not constrained by interaction with a second disk, which provides improved distributive and dispersive mixing.

Abstract: A controller (10) for two handed user input of linear and orientation data to control graphical images on a computer (12), and thus to permit the user to interact with application software running on the computer (12) in first person perspective. The controller (10) includes a first control sub-unit (14), for inputting data for two axes, and a second control sub-unit (16), for inputting two additional axes of data. Control-ware (18) is further included which combines the data from the first and second control sub-units (14, 16) into an integrated data set which is communicated to the computer (12). The control-ware (18) is capable of optional pre-processing tasks on the contents of the data set before communicating it to the application running on the computer (12). One example of such an optional pre-processing task is auto-leveling (100), whereby under desirable conditions the users first person perspective view in the graphical images is automatically urged toward level in an overrideable manner.

Abstract: A modular construction system (10), the preferred embodiment of which is directed toward the construction of structural walls (26). The construction system (10) employs precast wall units (12) and a variety of spacer/tensioning, spacer, tensioning, and extension assemblies (14, 16, 18, and 20). The wall units (12) contain a plurality of cavities (44) and are made of concrete with side walls (36) reinforced with prestressed tension wires (48). In the process of constructing a wall (26), the wall units (12) are stacked one upon the other onto threaded wall bars (24) that extend upwardly from a foundation (22). The spacer/tensioning assembly (14) and the spacer assembly (16) provide alignment during the stacking process and also create mortar joints (52). The spacer/tensioning assembly (14) and the tensioning assembly (18) are utilized in conjunction with the wall bars (24) to tension the wall units (12) onto lower wall units (12) and the foundation (22).
