Playful & Stunning IEM Wired EarbudsBlind

an iphone 5 / 5s case that will display a secondary screen on the back approximate dimensions: .5" x 5.5" x 2.4"

Designed a product which is planned on being launched on Kickstarter. Electronics are complete, but an enclosure 3D model needs to be designed so a prototype can be 3D printed. Finally, the 3D model would need to be create with draft, fillets, and other injection molding requirements.

Existing pneumatic mouth-blown siren whistles need a large volume of air at a fairly high pressure in order to produce a noise. Project Goals: Create a siren whistle model assembly (rotor, stator(s), housing) in Autodesk Inventor that that I can 3D print (I have Inventor myself, so I can modify part/assembly constraints and export STL for 3D printing) and I can experiment with the effect of changing constraints such as: different part/assembly sizes, number of rotor vanes, angle of rotor vanes, position and number of stator openings, etc. Ideally, the provided model with the default constraints produces a siren noise that uses less volume and pressure when blown through than existing products (such as those depicted at http://www.alibaba.com/trade/search?fsb=y&IndexArea=product_en&CatId=&SearchText=whistle+lips and on attached image). The model should also be moldable and assemble-able using conventional plastic production manufacturing methods. Provide constrained Inventor files upon completion. It is anticipated that reduction in size of the existing approach should produce the desired result. Higher pitched frequency than that produced by current commercial versions is OK. I've also included 2 photos of a: 1) stator/retention element (with round holes), 2) rotor and 3) stator/housing (red) from a "lip whistle" siren toy.

The item that will be called “pin” from now on in this document, should work as a fashionable hook to be attached to both a towel an the sand of the beach, so we ensure that the towel will keep its perfect position despite the wind or any other common adversity. There are already similar objects in the market that fulfill this objective as it can be seen in the images below (the technology to fix/tie/hook the towel to the sand could be different than the one shown in the images, we are opened to develop a new/different ways to fix the pin. That is the key point of this project.)

This is an industrial design for a hospital wall sensor with display, lights, and a button. The description of the project is contained in the attached file.
