HueMind is a resource that focuses on teaching users various intellectual property (IP) protections in order for a person to protect their ideas, inventions, concepts, or artistic or creative works from IP theft. This interactive app uses the responses to queries to gain general information about the user's idea. It recommends the form(s) of protection that best suits the idea. Each question offers a choice of answers from which the user selects the most appropriate one for their concept. HueMind provides a detailed explanation of each question to ensure the user has ample information to choose the best answer to the query. After the questions, the app displays the best protection(s) for their idea to the user. Each display of protection also comes with a comprehensive explanation of the type of protection(s) for the idea. It provides the form(s) of protection that best suits the idea. When developing a commercial product based on an idea, protecting the idea is a critical part of that process. However, idea protection is only one step in the process. Many people do not develop their ideas because they do not know the initial steps to develop their concept. In addition, many of them need to know who they can trust to assist them. HueMind does not leave the user hanging with only information about protecting an idea. After explaining the optimal idea protection, HueMind provides a resource, "The Starter Kit," that explains the idea development process and initial actions to take when one has an idea. This resource contains information that discusses and explains: 1. The steps in the product development and commercialization process 2. Initial actions in developing an idea 3. Essential questions to answer regarding your idea 4. Trade Secrets - Requirements for classification as a trade secret - Confidentiality agreement (NDA) for an initial meeting 5. Patents - Common misconceptions about patents - Factors to consider when deciding to file a patent application - Explanation of provisional patent applications - Flow diagram of the events in the patenting process - Patent costs and fees 6. Trademarks - Reasons for acquiring a federal trademark registration - Flow diagram of the events in the trademark registration process - Trademark registration costs and fees 7. Copyrights - Reasons for acquiring a federal copyright registration - Copyright registration costs and fees. This app does not ask for specific information about a user's idea. There is no fear of users exposing information about their ideas by using this app. An objective of this app is to provide the user with an initial base of information regarding how to develop and protect an idea. HueMind and its contents give the user the knowledge and confidence to step out and pursue their dreams, turning their ideas into products and services that can benefit society. Other resources are also available to assist users as they journey from idea conception to commercialization.

Physics Playground turns science into games you play with your hands. Fire a cannon, slide pucks across the ice, fold a protein, crack a cipher, bend starlight around a black hole and forge a star. Every game runs on real physics, chemistry, biology, math or computer science, so you learn by doing, not by reading. 63 GAMES, FIVE SUBJECTS From projectiles, orbits and lasers to entanglement and the Big Bang; atoms, reactions and batteries; cells, genes and the immune system; fractions, fractals and calculus; logic gates, sorting, networks and machine learning. Each game has its own controls and its own goal. PLAY AT YOUR LEVEL Pick Curious Kid, Teen, Undergrad or PhD. Games start on Easy, Normal or Hard to match, and PhD turns off the hints for numbers only play. Free Play lets you experiment with no clock. EARN EVERY STAR Clear stages, earn up to three stars, beat your best score and collect badges. Light up your constellation and unlock the Universe Tuner when you master them all. BUILT FOR IPHONE DUO Fold it into a tabletop and the hinge aims the cannon. Open it like a book and the game spreads across both halves, with controls on their own side. Close it and keep playing on the outer screen. NEW GRAPHICS, SMOOTH AT 120 HZ Glowing particles, warped spacetime, lensed starlight and live fractals, with haptics tuned to every bounce and blast. GO DEEPER Every game links trusted sources: textbooks, papers, lectures and courses. Works on iPhone, iPad, Mac and Apple Vision Pro. Ask Siri to open a game. No account, no ads, no tracking.
