A first end of the tether is connected to the elastomeric body, and a second end of the tether is connected to the fastener. The elastomeric body and the elongated tether may be monolithically formed. The tether apparatus allows a user to easily retrieve the handheld device if dropped.

The present invention provides methods and systems for a television protection and carrying device that includes a television protection and carrying device that includes a top portion with a base portion, a first end, a second end, and two sides, and a bottom portion with a first end, a second end and two sides. A receptacle disposed within each side of the bottom portion for receiving the second end of the top portion for selectively securing the top portion to the bottom portion, and a television is positioned within the top portion.

A carrying case for a portable electronic device is disclosed. Generally speaking, the protective case for a portable electronic device comprises a body section having a back surface and upturned sides, and a rim affixed to an edge of the upturned sides of the body sections, the rim defining an open area. Preferably, the body section is comprised of contrasting colors and forms a cavity defined by the back surface and the upturned sides. Further, the body section and the rim are preferably formed of the same material. A second protective section may be used to form a protective shell-like structure about the electronic device.

A piggybacking apparatus for mobile devices is provided. The piggybacking apparatus may be dimensioned and adapted to removably attach to the surface area of a mobile electronic device, such as a smart phone, in a generally coextensive manner. The piggybacking apparatus may provide a pouch for retrievably storing fluid and semifluid product that a user wants handy when they are handling the mobile electronic device, Through a conduit the user may urge the product from the pouch when and where desired. The piggybacking apparatus may also provide attachment points along a periphery thereof for operatively associating with the mobile electronic device in the coextensive manner, or alternatively to a case of the mobile electronic device, or even in between the two.

A foldable case is configured for removably receiving a separate and distinct mobile electronic device having a front device surface, a rear device surface opposite the front device surface, and a periphery extending between the front device surface and the rear device surface. The case includes first and second cover members and opposing hinge members. The first and second cover members include respective first and second rear walls, respective first and second peripheral rims, and respective first and second sidewalls extending between the respective rear walls and the respective peripheral rims and thereby define respective first and second recesses configured for receiving respective first and second portions of the device. The opposing hinge members each extend between adjacent locations at the respective peripheral rims of the first and the second cover members to hingedly connect the first and the second cover members.

An electronic device case is provided. The electronic device case may be adapted to secure electronic devices in a compartment space defined by a plurality of walls. A wall of the plurality of walls may be made from PVC matte or transparent material so that the electronic devices are visible while within the compartment space. The electronic device case may provide a plurality of grommets so that cables connected to the electronic devices may egress through the grommets so as to be utilized outside the compartment space, while the electronic devices are secured therein.

A key locator with tracking capability. A bent rod-shaped first member has a bent first end portion and a second end portion. A second member is configured for selectively retaining keys. The bent first end portion and second end portion are opposed to each other. The bend rod-shaped first member incorporates a planar bent center region intermediate to the bent first end portion and the second end portion to form the interior of the key locator. The bent first end portion and the second end portion are not urged against each other and are configured to allow the bent center region to hang from an edge. The bent first end portion of the bent rod-shaped first member substantially permanently and flexibly interlocks with the second member. A tracking device is connected to the key locator and is in radio frequency communication with a user's smart phone. In a preferred embodiment the tracking device enables a user of the smart phone to find the key locator if it is lost or misplaced.

A variety of improvements to portable electronic devices are disclosed, particularly electronic devices designed for use in and around water. The improvements include a more secure interface jack, improved waterproofing techniques, improved battery stability, and improved device functionality. One or more of the disclosed improvements may be incorporated into a variety of portable electronic devices.

The present invention provides a method for performing a graph-based prediction using a graph signal including obtaining a context signal; generating a graph signal based on a graph parameter set; obtaining a graph-based transform matrix based on the graph signal, wherein the graph-based transform matrix includes an eigenvector; obtaining a prediction vector using an optimal transform vector calculated through an optimization function; and generating a prediction signal using the prediction vector, where the optimization function has the context signal, an eigenvalue of a graph Laplacian matrix and the eigenvector as a variable.

A grip system comprises a protective case and a grip apparatus. The grip apparatus is attached to a back surface of the protective case. The grip apparatus includes a base, two flexible strips or straps, and a cap. The base is configured to be removably inserted into the recess in the back of the protective case. The two flexible strips are each attached to the base. The cap is proximate a top surface of the base when in a stowed position and extendable away from the top surface of the base when the cap is pulled outward to an extended position. Each flexible strip is configured or adapted to slide within a slot or channel in the cap. Each flexible strip slides into the slot when the grip apparatus is transitioned to the stowed position and slides out of the slot when transitioned to the extended position.
