Abstract: The present invention comprises an antenna coupling arrangement for connecting a portable communication device to a further signal transmission line. The portable communication device has an external radiative antenna. The coupling arrangement comprises a housing of generally rectilinear configuration having left and right sides, a lower side and a back side arranged to enclose a portable communication device. An antenna coupler is hingedly supported on the housing to pivotably mate with the external antenna of a portable communication device enclosed within the housing. The antenna coupler is connected to a transmission line for further connection to a further antenna or transmission line.

Abstract: The present invention comprises a signal generator for sending an electrical signal from an expandable, flexible layer of material, the signal generator comprising an upper layer of flexible, resilient material and a lower layer of flexible, resilient material which between them define a cavity for enclosing an expandable material such as a cellular foam or gas, whereupon localized distortion of one of the layers of flexible material, effects a signal generation within the structure, which is transmissible through a proper circuit to an outside electrical device. A circuit may be arranged adjacent a plurality of said keys which senses when several of said keys are depressed in a skewed or sideways manner, so as to effect movement of a cursor or pointer on a monitor in communication with a processing unit and said keyboard.

Abstract: The invention comprises a plasticating machine for the working and forcing of plastic material into a mold, said machine including an elongated housing having a first or proximal end and a second or distal end, an elongated screw shaft with a screw flight therearound, the screw shaft being rotatably supported in the elongated housing, for the working of plastic between the screw shaft and the elongated housing with at least one delivery conduit generally longitudinally arranged through the screw shaft, from a proximal end to a distal tip end thereof. The conduit may be arranged to be movable with respect to the screw shaft to permit delivery of a medium through the screw shaft to any plastic being driven from the machine. The medium may be any single or combination of components selected from the group comprising vapor, liquid, gas, powder or solid, to control the machine or treat any plastic being driven therefrom.

Abstract: The invention includes retrofitting a plasticating machine for the working and forcing of plastic material into a moldor die, the machine including an elongated housing having a first or proximal end and a second or distal end, and elongated screw shaft with a screw flight therearound. The screw shaft is rotatably supported in the elongated housing, for the working of plastic between the screw shaft and the elongated housing with at least one delivery conduit generally longitudinally arranged through the screw shaft, from a location proximal to the distal tip end of the screw. To accomplish such delivery, the screw shaft is replaced with a corresponding screw shaft with a bore extending through the distal tip end thereof, or the existing screw shaft is machined to have such a bore extend therethrough, from location proximal to the distal end out through the distal tip end. The bore in one embodiment may extend completely through the screw shaft, from its proximalmost end to its distalmost tip end.

Abstract: The invention comprises a plasticating machine for the working and forcing of plastic material into a mold, said machine including an elongated housing having a first or proximal end and a second or distal end and an elongated screw shaft with a screw flight therearound, the screw shaft being rotatably supported in the elongated housing, for the working of plastic between the screw shaft and the elongated housing. At least one pair of coaxial spaced apart delivery conduits are generally longitudinally arranged through the screw shaft, from a proximal end to a distal tip end thereof. A tubular mesh generating apparatus is arranged at the distal end of the coaxially conduits to generate/weave and feed a tubular reinforcement mesh along the length of the annular delivery channel to a plastic melt at its distalmost end. A movable forming tool is supported adjacent the distal end of the innermost conduit of the coaxial conduits.

Abstract: The present invention includes a flexible, pressurizable keyboard made of resilient layers of plastic material, with molded keys which are deformable when pressed so as to send a signal to an electrical device. The keys are arranged with a flexible electrical circuit thereattached, which when depressed, establish a proper complete circuit.

Abstract: The present invention comprises a docking system for connecting a portable communication device to a further signal transmission line. The portable communication device has an external radiative antenna. The docking system for the portable communication device comprises a shielded housing for receivably enclosing at least a portion of the external radiative antenna of the portable communication device. A coupling probe is mounted within the shielded housing for radiatively coupling the external antenna of the portable communication device and the further signal transmission line via radio frequency energy therebetween.

Abstract: The present invention comprises a signal generator for sending an electrical signal upon receipt of an input force, the signal generator having a first outside layer of flexible, resilient plastic with a periphery and an inner surface, a second outside layer of flexible, resilient plastic having a periphery and an inner surface, the first and second layers joined at least at their periphery to form walls defining primary chamber. The primary chamber also has at least one inside layer of flexible, resilient plastic having a periphery and a first and second surface, the inside layer also being joined at its periphery, to the walls of the primary chamber to sub-divide the primary chamber into a plurality of adjacent sub-chambers. A pressurized fluid may be disposed in each of the sub-chambers and an electrical circuit may be arranged in at least one of the sub-chambers, to effectuate the transmission of an electrical signal from the primary chamber upon receipt of an input force within the primary chamber.

Abstract: An arrangement for permitting the safe, shielded use of a hand held cellular telephone in a structure such as a building or a vehicle or airplane through the use of a dock which receives the cellular telephone and its short external antenna. The dock includes a housing which encloses the antenna and couples it to a more distant antenna external to the structure through a sheilded transmission cable, where the RF signals may be sent and received without harm to the person using the cellular telephone.
