Abstract:
A selectively reinforced hybrid metal-composite structural element can include a metal element and a composite material. The composite material can be bonded to the metal element by an adhesive layer including a polymer matrix using a radiation curing process, resulting in insubstantial or negligible residual stresses at the bond line between the metal element and the composite element. The structural element also can include a metal closeout cap to provide a barrier from a corrosive atmosphere, and the adhesive layer can encapsulate the composite element to provide a corrosion-resistant barrier between the composite element and the surrounding metal.
Abstract:
A multiple-sided activity device for toy blocks is disclosed. The activity device has a first side including a first activity adapted to interact with at least one of the plurality of toy blocks. The activity device also has a second side distinct from the first side, the second side including a block recognition mechanism configured to selectively interact with any of the plurality of toy blocks to identify which of the plurality of toy blocks is interacting with the block recognition mechanism and to produce block-specific sensory stimulating output.
Abstract:
The invention includes a toy having a translucent body that includes a first surface and a second surface. A light source is disposed opposite the first surface. The first surface includes an image of a facial feature in a first position and the second surface includes an image of the same facial feature in a second position. When the light source is illuminated, the facial feature appears to be in the first position and when the light source is not illuminated, the facial feature appears to be in the second position. An audible output generator produced audible output simultaneously with illumination of the light source.
Abstract:
A system and method for an interactive, Internet-based videoconferencing multicast operation which utilizes a video production studio with a live instructor giving lectures in real-time to multiple participating students. The videoconference multicasting permits the students to interact with the instructor and other installations during the course of the lecture. In the case of software training, the system and method also utilize Internet-based application sharing and collaboration to permit the students at remote locations to drive a studio-based computer with the software for which the training is being given. The software screen is then used as a background with the instructor being able to literally point to areas of the screen which are being discussed. The instructor has a set of monitors in the studio which allow him/her to see the students on-location. In this fashion, the students can see at their computer screens the instructor “walking” around their computer screen pointing at various items in the screen. Furthermore, a system and method for on-line testing, evaluation and reporting is disclosed wherein test questions, which can be created on the fly by a test administrator, are stored in a database and associated with one or more test numbers and whereby each time a student requests to take a test, the test is “built” and the order of the questions is randomized to avoid cheating. Test evaluation data is cross-correlated and made instantaneously available to students and their sponsoring employer.
Abstract:
A captive ball and socket joint where the socket is made from bearing material which is encased in a metal shell, thereby forming a socket around the ball head on the end of a ball stud. The metal shell is cup-shaped and has its base wall apertured so that the ball formed with internal wrenching socket is accessible through the aperture when the ball and the bearing socket are placed into the cup-shaped shell. A flat steel connector lug is pierced with an opening and the wall of the metal cup-shaped shell is secured within the opening by welding. The edge portion of the shell is deformed to render the ball and socket captive in assembly with the lug. The hole in the base wall of the shell permits access for insertion of a rotary drive tool to engage a formation in the ball component to rotate the ball component and secure it to a machine element such as a brace or bracket. The bearing socket can be one or two pieces and can be made from metal bearing material or a plastic bearing material. The method of assembling the joint envisages use of techniques to avoid destruction of the characteristics of the bearing material.
Abstract:
A reconfigurable target/projectile activity entertainment device is disclosed, wherein the device includes a projectile, a target having a target area and a reversible base connectable to the target. The target is in the form of a hoop or ring and is disposed above the reversible base. The hoop has an opening therein that forms the target area. The hoop contains a sensor that detects a projectile passing through the target area and communicates with a sensory generator to generate sensory-stimulating output (i.e., lights and sounds). Projectiles directed through the target area drop to the reversible base below the target area. The reversible base has a first side and a second side. The first side is concave for collecting a projectile that drops thereon. The second side is opposite the first side and has a convex side that deflects projectiles dropping thereon to deflect the projectile away from the device. The reversible base can be reconfigured between a first mode wherein the concave side faces the target area and a second mode that wherein the convex side faces the target.
