DESCRIPTION OF PREFERRED EMBODIMENTS

(8) This disclosure relates to a Light Floatable Structure that can be attached to the back cover of a Mobile Electronic Device rendering the composite structure floatable in water or other liquids because the Specific Gravity of the composite structure is less than 1. The shape of Light Floatable Structure conforms to the footprint of the Mobile Electronic Device on which it will be attached and detached in that the sides of Light Floatable Structure do not extend laterally beyond the length or width dimensions of the Mobile Electronic Device.

(9) In a preferred embodiment, the Light Floatable Structure comprises a body of low-density foam or air or other gases to create a composite structure when attached to the Mobile Electronic Device. The thickness of the Light Floatable Structure body is determined by that required to produce a composite structure that has a Specific Gravity that is less than 1. That is, the Light Floatable Structure body has dimensions of width, length that are substantially the same as the width and length of the Mobile Electronic Device. The Light Floatable Structure has a depth Zfe that is sufficient to produce a composite structure having a Specific Gravity less than one which may include portals formed in the Light Floatable Structure) to cause the composite structure to float when dropped into water.

(10) The volume of the Light Floatable Structure was computed using the width W*length L* (which are the same as the width and length of the Mobile Electronic Device) to solve for a depth of the Light Floatable Structure (Zfe). The depth (Zfe) of the Light Floatable Extension is calculated to create a composite structure that floats by forcing the Specific Gravity of this composite to be <1 as illustrated in Sheet 1.

(11) The Specific Gravity of this composite is given in equation (1),
SG=(Med+Mfe)/(Ved+Vfe),  (1)
where Med is the mass of the mobile electronic device. In this example, Med=Ded*W*L*Zed, where Ded is the density of Mobile Electronic Device since Ded=Med/Ved. Mfe is the mass of the Light Floating Extension, and is given by the equation (2),
Mfe=Dfe*(W*L−nAp)*Zfe,  (2)
where and nAp is n portals each a area Ap.

(12) Ved is the volume of the Mobile Electronic Device. In this example, Ved=W*L*Zed, where Zed is the thickness of the Mobile Electronic Device.

(13) Vfe, on the other hand, is the volume of the Light Floatable Extension. In this example Vfe=(W*L−nAp)Zfe.

(14) The values of Dfe, Ded, L, W and Zed are given in sheet 1, set forth below. From these, a solution for the value of Zfe that will give a SG less than 1, as given by the following equation (3),
Zfe=(SG*W*L*Zed−Ded*W*L*Zed)/[Dfe*W*L−SG(W*L−nAp)],  (3)
where the value Zfe is calculated with and without a portal and for various values of SG.

(15) In this example, the total thickness Zt=Zfe+Zed is calculated for inclusion or not of a portal and various values of parameters of the Electronic Device and Floatable Extension. It is clear from examination of this sheet that the density of the Floatable extension has a profound effect on the total thickness Zt of the attached structure. Thus, the value of 0.015 g/ccm, foam can be obtained commercially from suppliers such as Worldwide Foam Ltd. Such Light floatable Extensions can also be produced by constructed of plastic in a rectangular shape with dimensions Wfe, Lfe Zfe sealed along the edges to form a sealed hallow structure, or formed using a 3 dimensional printer that would create an array of closed cells in the shape of Wfe, Lfe. Zfe.

It can also be seen from sheet 1 the effect of a portal on the Zt is also insignificant with this low density Floatable Extension.

(17) The Light Mobile Floatable Structure can be attached and detached from the Mobile Electronic Device multiple times. Attachment of the Light Floatable Structure to the Mobile Electronic Device can be accomplished as described in independent claim 1 and supported using several different adherence materials described in several dependent claims.

(18) The variety of adherence materials that may be used to make the Light Floatable Structure and Mobile Electronic Device detachable with each other include, but are not limited to, restickable glue, magnetic tape, hooks and loops (Velcro), 3M Dual-Lock, and suction tape. Each of these adherence materials can be attached and detached using a hand applied force. The attachment is generally applied as a direct force and detachment is accomplished with an apposing force, where a torsional apposing force is found as most appropriate. These attachment and detachment methods are shown in FIG. 3.

(19) A preferred embodiment of this invention is formed by bonding the Light Floatable Structure and the Mobile Electronic Device using a Restickable glue product such as that made by 3M/Scotch, or Removable Glue Stic by @Removable, or Washable School Glue stik by Elmers. These products provide a bond which allows the composite structure to be dropped in water and float without the bond breaking, but the composite structure can be separated with an appropriate force that allows separation of the Light Floatable Structure from the Mobile Electronic Device at the interface of the two structures, and may be reattached for use multiple times. Restickable glue is a sticky substance that can be sprayed, rolled, or otherwise dispersed onto a surface, making that surface detachable to other surfaces multiple times by applying restickable glue to the base of the Light Floatable Structure. The Light Floatable Structure can then be attached and detached from the Mobile Electronic Device at the plane of the detachable restickable glue.

(20) In another Preferred Embodiment of this disclosure, materials that form a bond to one another when pressed together are used, but may be attached and detached multiple times. Such materials may be used to attach and detach a Light floatable Structure to a Mobile Electronic Device multiple times. Such materials include “hooks and loops” technology to form a temporary, re-bondable interface between the Light Floatable Structure and the mobile device. In this case it is preferable to attach the “loops” to the mobile device and the “hooks” to the Light Floatable Structure because it is softer and less objectionable as part of the detached mobile device than the hooks, but either way of attaching the “hooks and loops” are included in this patent application. “Hooks and loops” certainly meets the criteria of providing a temporary bond between the Light Floatable Structure and the mobile device that allows the composite structure to float when dropped in the water and is detachable and re attachable multiple times.

(21) Hook and loop materials, such as Velcro and any other hook and loop type materials and 3M Dual-Lock, may be attached to opposing surfaces to be fastened. There are a variety of hook and loop materials that may be used. The hook material consist of many tiny hooks that have been sewn into a flat material, likewise, the loop material consist of many tiny loops sewn into a flat material. The two pieces of material adhere together when the hooks catch in the loops as the two pieces of material are pushed together. After the hooks and loops are attached that can be detached by hand force. There also materials similar to hooks and loops, such as 3M Dual-Lock, that allow to objects to be detachable. By applying the loops material to the back of the Mobile Electronic Device and hooks material to the base of the Light Floatable Structure, the Mobile Electronic Device and the Light Floatable Structure can be attached by allowing the hooks to securely grab the loops and detached by hand force. The 3m Dual-Lock material is a bit different in that the two sides are the same material but attach together by applying a force and detach when an opposite force is applied. The Light Floatable Structure can be attached and detached from the Mobile Electronic Device at the plane of the detachable material as shown in FIG. 4.

(22) In another embodiment, a substance known as suction tape is used to adhere the Mobile Electronic Device to the Light Floatable Structure.

(23) Suction tapes, such as Airstick and Geckskin, have a glue like side to adhere to the surface of an object. The other side of the suction tape consists of many tiny suction cups that allow the object to become detachable to other surfaces. By applying suction tape to the base of the Light Floatable Structure, the Light Floatable structure can be attached to and detached from the back of the Mobile Electronic Device. The Light Floatable Structure can be attached and detached from the Mobile Electronic Device at the plane of the detachable material.

(24) Still another embodiment of the invention is to use a thin magnetic film to adhere the mobile device to the floatable extension. This thin magnetic film can be attached to the bottom of the mobile device and to the top surface of the Light Structure. The Light Floatable Structure can be attached and detached from the Mobile Electronic Device at the plane of the detachable magnetic elements.

(25) In another embodiment, a Magnetic tape has a sticky side and a magnetic side. The sticky side may be attached to the surface of an object leaving the magnetic side exposed. When the magnetic tape is adhered to both surfaces, the two objects may be attached by magnetic force and pulled apart by hand force. By applying magnetic tape to the base of the Light Floatable Structure and the back of the Mobile Electronic Device, the Light Floatable Structure and Mobile Electronic Device can be attached by way of magnetic attraction and detached by hand. The Light Floatable Structure can be attached and detached from the Mobile Electronic Device at the plane of the detachable magnetic materials.

(26) In yet another embodiment, a light superstructure forms the outline of a Light Floatable Structure using a vertical extension of the footprint of the Mobile Electronic Device. This superstructure is formed using a light rigid material that may be attached and detached to the foot of the Mobile Electronic Device using any of the adherent materials described in the other embodiments and other embodiments.

(27) An inflatable balloon is attached to this superstructure that, when inflated, creates a confined air volume that forms the desired Light Floatable Structure. In all of the earlier embodiments, the Light Structure is composed of a light foam material, while in this last embodiment, the Light Floatable Structure is formed from the contents of a balloon and a gas such as air confined by a superstructure rather than the light foam like material in the earlier embodiments. This form of the Light Floatable Structure A simple nozzle that allows a mouth or other gas injector to be used to inflate the balloon. The necessary portal are provided on these balloon devices by marking the balloon in the appropriate locations while deflated and attaching tubes with a water proof glue to the input and exit marked on the locations on the balloon. The superstructure with attached balloon uses one of the attachment materials described in the dependent claims of this application to form a detachable bond to the Mobile Electronic Device for easy attachment and detachment of this device from this Light Floatable Balloon apparatus.

(28) In these embodiments, the shape of the Light Floatable Structure fits the vertical extension of the footprint of the Mobile Electronic Device. The Light Floatable Structure also includes textured edges would be used to avoid shapes that would tend to apply torsional forces to be applied to the composite structure upon entry into water or other liquids. Such textured edges would tend to avoid de bonding the composite structure as illustrated in FIG. 5.
