Abstract: A laser test card according to the present invention comprising a thin planar multi-layer material, which may be cut to a desired length and width, is exposed to a beam directed to the laser test card top surface from a laser under test, and reveals successive visibly contrasting layers under the top surface according to the incident laser beam energy at that particular point or any point of the X or Y dimension (cross-section) of the beam. In the preferred embodiment, several different layers of sharply different colors are used.

Abstract: An improved, dual diode convergence module which focuses the light energy of at least two separate diode chip laser wavelengths of into a single beam and, thus, which derives the benefit of both wavelengths.

Abstract: In a continual and integrated approach to Internet banner display rights, a party acquires long-term banner display rights on published web sites of other entities, in a manner so as to ensure full and continual control over the content, look and functionality of the acquired banner space. A variety of different forms of compensation can be provided to the entities which publish the web sites, in exchange for the acquisition of the banner space. The Internet banner is multifunctional, utilizing menus, links and similar user interface items, to operate as a portal to a variety of informational content and services, such as e-commerce, search engines, and the like. These services might be provided by the party which owns the banner space, or by third parties. The banners which appear in the spaces acquired from multiple publishing sites are organized into a networked system, to provide users with integrated and consistent access to the available services.

Abstract: A light returning target for a photometer. The light returning target comprises a ball lens, and a cradle. The cradle has a hemispherical receptacle in which the lens is intimately received. Preferably, the lens is formed of fused silica, the receptacle is polished sufficiently to reflect, more than it scatters, light, and at least the surface of the receptacle is formed of a material that absorbs, more than it reflects, light.

Abstract: A composition for a lubricating fast-setting epoxy compound comprising substantially equal amounts of an epoxy base and an epoxy accelerator. The epoxy base comprises: a first micro-crystalline filler, a first talc, a hardenable epoxide containing liquid; and a titanium oxide. The epoxy base can also include a flatting agent. The epoxy accelerator comprises: a second micro-crystalline filler, a second talc, a methylamino accelerator, and a hydrocarbon resin. The epoxy accelerator can also include a modified aliphatic amine, an acrylic resin, a coloring agent, or combinations thereof.

Abstract: A method for making a lubricating fast-setting epoxy compound comprising: mixing under vacuum dispersion a first micro-crystalline filler, a first talc, and a titanium oxide into a hardenable epoxide containing liquid forming an epoxy base. A second micro-crystalline filler, a second talc, and a hydrocarbon resin are mixed forming an accelerator mixture. A methylamino accelerator is mixed into the accelerator mixture forming an epoxy accelerator. Substantially equal amounts of the epoxy base and the epoxy accelerator are mixed to form the lubricating fast-setting epoxy compound having a high lubricity and a curing time ranging from two minutes to twelve minutes. Adjusting the mixing speed and temperature of the epoxy base, the accelerator mixture, and the epoxy accelerator is contemplated to promote homogeneity. The epoxy base can also include a flatting agent. The epoxy accelerator can also include a modified aliphatic amine, an acrylic resin, a coloring agent, or combinations thereof.

Abstract: An electronic business card device is provided including a memory constructed and adapted to store at least one electronic business card consisting of at least an image of a business card along with associated card information derivable from and associated with the business card, a sending mechanism constructed and adapted to send a stored electronic business card to other devices, a receiving mechanism constructed and adapted to receive an electronic business card and associated card information from another device, and a storing mechanism constructed and adapted to selectively store the received electronic business card in the memory, the storing being based at least in part on at least some of the received associated card information.

Abstract: An electrically operated paintball gun operable to shoot paintballs including a barrel, a trigger, and a breech connected to a rear end of the barrel, as well as a bolt movable in the breech between a rearward position and a forward shooting position. A spring biases the bolt towards the rearward position. A pneumatic circuit is provided to drive the bolt towards the forward position and includes a control valve in the form of a solenoid valve to receive gas under pressure and direct it into a chamber at the rear of the bolt when the gun is shot. An electronic circuit controls the pneumatic circuit and is operated by an electrical switch operated by the trigger. A gas valve mechanism is opened by engagement by the bolt, when the latter is driven forwardly to the shooting position, to permit the passage of relatively high pressure propellant gas into the barrel to propel a paintball.

Abstract: An improved lightweight, durable collapsible scooter which is safe to operate and is easy and convenient to collapse, transport and store. The scooter has a steering assembly which is pivotally secured to the front portion of a frame assembly. A front wheel is rotably secured to the steering assembly and a rear wheel is rotably secured to the rear portion of the frame assembly. A hydraulic gas spring strut is pivotally secured at one end to the steering assembly and at the other end to the frame assembly. When extended, the collapsible strut releasably locks the steering assembly in an upright operating position for operation by a rider, and when the strut is in a compressed or collapsed position, it releasably locks the steering assembly in a position generally parallel to and adjacent to the frame assembly, for storing or transporting the scooter.

Abstract: A paint ball is disclosed having a gelatin capsule which defines a closed interior chamber. A fill material is contained within the interior chamber and this fill material contains 1%-65% polyethylene glycol, 25%-45% starch, up to 0.5% dye and the balance water. Additionally, the capsule material contains 9%-17% sorbitol, 35%-45% gelatin, 10%-20% glycerine, up to 10% starch, up to 0.5% color and the balance water.
