Methods and systems for training a broad population of learners in the field of robotics and automation technology based on physical interactions with a robotic training system are described herein. Specifically, a robotic instructor provides audio-visual instruction and physically interacts with human learners to effectively teach robotics and automation concepts and evaluate learner understanding of those concepts. In some examples, a training robot instructs and demonstrates encoder operation, feedback control, and robot motion coordination with external objects and events while physically interacting with a human learner. In some examples, interlock logic and waypoints of the training robot are programmed by the human user while the training robot physically interacts with the human learner. In a further aspect, a training robot evaluates the proficiency of a human learner with respect to particular robotic concepts. Future instruction by the training robot is determined in part by the measured proficiency.

A computer-implemented method teaches a user to evaluate a gemstone, such as a cut diamond. The method includes providing a computer system connected to an apparatus capable of capturing an image of a gemstone. The computer system is arranged to process a received image of a gemstone to determine one or more optical properties of the gemstone. In one aspect, the method presents on a display of the computer system a series of pre-stored screens comprising a graphical representation how the cut of a gemstone affects its light handling ability, and a user interface screen. The user interface screen allows the user to control the operation of the apparatus to measure the one or more optical properties of a particular gemstone provided to the apparatus, to view an image of the gemstone measured, and to view representations of the measured one or more optical properties.

This invention involves a balance scale with a base, a balance arm support, a balance arm, a pointer, and a movable label plate containing descriptions. The balance arm has a tray on each end, where one tray holds an article representing mankind with sin, and the other tray holds an article representing the redemptive work of Jesus Christ. The articles on each tray are of equal or approximately equal weight. The scale rotates when the weight of the articles are added to or removed from the trays, and the scale rotation will determine which description the pointer will point to. This invention can be used as a Christian teaching aid showing the benefit of choosing to accept the death of Christ as payment in full for our sins, along with showing the consequence of our refusal to accept the death of Christ as payment for our sins.

Active vibration isolation (AVI) systems are becoming more available in various markets, one such market being vehicle operator seating. Unfamiliarity with the performance of such systems may cause users initial perceptions of system performance to be unfavorable. AVI systems can include a demonstration system capable of providing simulations too users of various types of vibration isolation systems under various input conditions, so that users can be introduced to the system benefits over other systems before using an AVI equipped product in its intended application.

An audio demonstration kit encourages understanding of audio concepts by enabling children to construct and study speaker performance. In a particular embodiment, the audio demonstration kit includes a paper speaker and instructions. The paper speaker includes a backplate, a suspension, and a diaphragm cut from a single sheet of paper. The demonstration kit may feature an amplifier that is configurable to accommodate various hardware additions as a child is ready for more progressively challenging construction. For example, the amplifier of an embodiment allows single and dual mode operation, as well as drives a rotary motor and is coordinated with a strobe light. The amplifier of an embodiment is synchronized with the strobe light and a moveable platform to create the impression of that jiggling figures attached to the table are dancing. Interfaces with smart phone, recording, and other technologies further enhances and encourages the learning experience.

A configurable panel display includes panel frames configurable to support respective panels, adjacent ones of the panel frames being pivotably connected along opposing edges, each panel frame having intersecting sides formed by tubular frame members, and a cap hinge assembly pivotably connecting two adjacent ones of the panel frames. Each cap hinge assembly includes two frame corner pieces, each frame corner piece interconnecting tubular frame members of two intersecting sides of a respective one of the adjacent ones of the panel frames. Each frame corner piece includes projections received within the interconnected tubular frame members, a central corner piece body from which each of the projections integrally extends, a hinge cap spanning the two frame corner pieces, and two fastening members, each fastening member connecting the hinge cap to a respective one of the frame corner pieces.

An apparatus providing for virtual use of one or more virtualized smart home devices. The apparatus includes a simulation app download element and a web host. The simulation app download element is disposed in a cloud-based file server, and is configured to download a simulation app to a smart phone that is collocated with a computer, upon which the one or more virtualized smart home devices are simulated. The web host is disposed in the cloud-based file server, and is configured to provide content to the computer to simulate the one or more virtualized smart home devices and, responsive to control commands transmitted via the simulation app, is configured to transmit corresponding control commands to the computer that change simulated states of the one or more virtualized smart home devices such that a user experiences control of the one or more virtualized smart home devices.
