Abstract:
The invention is a hovercraft with multiple lift chambers which are operable independently of each other. Independently-operable pivot arm assemblies connect each lift chamber to the hovercraft main body, and his gives the hovercraft the ability to travel over uneven surfaces, traverse obstacles that would block conventional hovercrafts, and climb or descend even severe inclines. The hovercraft also includes side thrusters which allow it to maintain its vertical position on an incline while traveling laterally across the incline.

A data display using the micropackage, and a method of making the data display.
Abstract:
Ownership of a secure process is enabled with a cryptographic system. Methods initializing and operating the cryptographic system transfer control from the loading program to the loaded program and, in essence from the cryptographic system vendor to its end-user. As a result, ownership of the secure process can be relinquished to the end-user so that it alone can subsequently use the cryptographic system to control the secure process of loading and running its user-programs. The cryptographic system and methods allow for secure operations and protect against tampering with application software. The application program is retrieved from an encrypted file in external memory and authenticated by the cryptographic system before being executed.
Abstract:
The meter enclosure cover includes a cylindrical tube attached to a cover which allows the face of the meter to be exposed while maintaining the meter at a low profile in the meter enclosure. The cylindrical tube has a flange on one end to provide a surface on which a gasket can be attached. The angle at which the cylindrical tube meets the cover can vary to allow for proper meter viewing as well as protection from water. The flange on the cylindrical tube rests firmly against the circumference of the meter base. All faces of the meter enclosure cover which contact the meter and meter enclosure are sealed by a continuous gasket to protect against dirt, dust, oil and water. The meter enclosure cover is attached to the meter enclosure with a secure locking device. Construction of the meter enclosure cover can be from any appropriate material. Construction methods for the meter enclosure cover include (but are not limited to) cloth lay-up molding, thermoforming, injection molding, as well as cutting and welding/riveting.
Abstract:
A method of forming an opening or cavity in a substrate, for receiving an electronic component, consists of or includes providing a patterned opaque masking layer on or adjacent a first major surface of the substrate, the masking layer having an opening overlying the position where the cavity is to be made, removing material from the substrate by laser ablation through the opening thereby forming an opening or cavity of a suitable size for receiving said electronic component.
Abstract:
A lightwire segment in the form of an elongated substrate frame composed of a flat flexible thin elongated sheet of plastic dielectric material having a copper film laminated on at least one side; a plurality of cavities longitudinally spaced along the elongated substrate, a LED diode having first and second contacts embedded in each of the cavities of the substrate; the copper film on one side of the substrate defining two interconnects separated by a dielectric space, one interconnect having a tab bonded to the first contact of each LED diode, and the other interconnect having a tab bonded to the second contact of each LED diode. A lightwire made from a plurality of segments that are bonded together in series or parallel. A micropackage made from a substrate frame composed of a flat flexible thin sheet of plastic dielectric material having a copper film laminated on one side defining rows and columns of component sites separated from one another by thin webs to be readily detached from the substrate frame. The micropackage has indexing elements to position the substrate frame relative to a machine that can pick the component sites out of the frame. Each component site defines a cavity formed in the substrate, and the copper film laminated on the substrate defines two separated interconnects, each having a tab extending into the cavity formed in the substrate. An electrical component having contacts is positioned in the cavity and its contacts are bonded to the tabs.
Abstract:
A micropackage, an interposer, in which a flexible dielectric plastic substrate composed of a dielectric layer with a layer of conductive film (copper) on one surface is photo-imaged to define at least two electrical interconnects each including a tab formed in the copper film. The interconnects extend out over the edges of the plastic substrate in at least two directions to form at least two flanges. A cavity is formed in the plastic substrate such that the tabs of the at least two interconnects extend into said cavity. An electrical device or an electro mechanical device having contacts is received in the cavity of the plastic substrate with its contacts engaged with and bonded to the tabs of the interconnects. The method of making, and the use of the interposer in a further substrate, e.g. a PCB, that contains electrical connections or circuitry to which the interposer is connected to by the flanges.

Abstract:
The present invention relates to naturally-occuring growth hormone mutations; to a method for detecting them and their use in screening patients for growth hormone irregularities or for producing variant proteins suitable for treating such irregularities. In one aspect there is disclosed a detection method for detecting a variation in GH1 effective to act as an indicator of GH dysfunction in an individual, which detection method comprises the steps of: (a) obtaining a test sample comprising a nucleotide sequence of the human GH1 gene from the individual; and (b) comparing the sequence obtained from the test sample with the standard sequence known to be that of the human GH1 gene, wherein a difference between the test sample sequence and the standard sequence indicates the presence of a variation (hereinafter “variant of GH1”) effective to act as an indicator of GH1 dysfunction characterised in that the test sample is obtained from an individual, either or both: exhibiting intra-uterine growth retardation (IUGR), defined as sufficient foetal height velocity diagnosed by standard methods known in the art; and/or small for gestational age (SGA), defined as insufficient (small) foetal body size (weight and/or length) for gestional age diagnosed by standard methods known in the art.
