Abstract: A self-attaching supplemental battery for a cellular phone comprises a housing containing a rechargeable battery. A releasable attachment pad is affixed to an attachment side of the housing to releasably couple the housing and the rechargeable battery to a back of the cellular phone. A cover is removably carried by the housing, and selectively locatable on either side. The cover comprises a panel sized and shaped to cover the releasable attachment pad in a protection location when located on the attachment side of the housing, and to expose the releasable attachment pad in a storage location when located on the face side of the housing.

Abstract: A lens cover selectively covers and exposes a, camera lens on the back of mobile device, such as a cellular phone. The lens cover can be adhered to the back of the mobile device. The lens cover has a flap that pivots 180 degrees about an axis parallel with the back of the mobile device, and between an open/storage position and a closed position. The flap can be off-set with respect to the axle so that in the open/storage position, the flap is adjacent or abutting to the back of the mobile device, and so that in the closed position, the flap is spaced-apart from the back of the mobile device, creating a gap to receive a protruding camera or camera lens. The flap can also comprise a detent to maintain the flap in a selected position until selectively moved.

Abstract: A stereoscopic image viewer comprises a frame to be physically coupled to a handheld electronic device. The frame comprises a face plate having a pair of lens sockets with a pair of lenses, and a pair of side arms with a pair of slots to receive the handheld electronic device. The lenses can be coupled in the sockets by twist-to-lock couplings. A forehead pad comprising a squat dome is disposed on the face plate.

Abstract: A holder device to hold a mobile device with respect to a vent or a surface of a vehicle has a ball-and-socket joint pivotally coupling together a clip to engage the vent or surface, and a clamp to releasably carry the mobile device. The ball-and-socket joint has a ball pivotally disposed in a socket. The ball-and-socket joint has a friction fit or an interference fit between the ball and the socket sufficient to hold a position between the ball and the socket under a weight of the clamp and the mobile device without an applied external force.

Abstract: A stretchable strap cover for a handheld electronic device has a flexible and elastic pad with four apertures formed in the pad and extending through the thickness of the pad, and four straps defined between the four apertures and the perimeter of the pad. The pad has at least two configurations, including: 1) an initial configuration in which the pad is separate from the handheld electronic device, an in which the pad is unstretched with an initial unstretched perimeter, length and width, and in which the pad is flat and disposed in a flat layer having a thickness the same as the thickness of the pad, with the straps and the apertures disposed in the flat layer; and 2) an installed configuration in which the pad is coupled to the handheld electronic device, the pad being stretched and under tension, and the straps being disposed out of the flat layer.

Abstract: A folding stand for use with a mobile device comprises a front pair of legs being spaced-apart from one another defining a gap, and having a front foot at the bottom end interconnecting the front pair of legs. A rear leg pivotally coupled to the front pair of legs. The front pair of legs and the rear leg having at least two positions with respect to one another, including: 1) a collapsed retracted position in which the rear leg is folded between the front pair of legs, and with the mobile device removed from the front foot; and 2) an expanded extended position in which the rear leg is unfolded from between the front pair of legs with bottom ends of the front and rear pairs of legs configured to be disposed on a support surface, and configured to receive the mobile device disposed on the front foot and leaning against the front pair of legs.

Abstract: A pocket is fixed to a cellular phone and has a pouch removably receiving a rectangular card to selectively couple the rectangular card to the cellular phone. The pouch has inner and outer panels, and a pair of elongated slots formed in the outer panel to form an elongated strap therebetween with opposite distal ends attached to and formed with the outer panel.

Abstract: A universal case has a single, unitary, elastic body of flexible and resilient material that can stretch to cover both smaller and larger mobile devices. The body has a side wall, a front perimeter lip, a rear perimeter lip and a web defining a cavity and being integral with one another and formed together from the flexible and resilient material as the single, unitary, elastic body. The side wall, the front perimeter lip and the rear perimeter lip define a perimeter channel to extend around a perimeter of the mobile device. The front perimeter lip defines a cavity and has corner lips with a wider width to define corner pockets. A groove is disposed in the channel, and extends into an inner surface of the side wall.

Abstract: A swivel finger strap device for a mobile device comprises a base with an adhesive layer configured to be adhered to a back of the mobile device. An aperture is formed in the center of the base. A cap is rotatably coupled to the base. A post extends from the cap and through the aperture in the base, and defines a pivot axel about which the cap rotates with respect to the base. The cap has an interior cavity on an interior side of the cap, and is sized and shaped to receive substantially all of the base therein. A flexible strap is affixed to the cap. The flexible strap and the cap form a loop to receive one or more fingers of a user's hand.

Abstract: A mobile device stand comprises a substantially rigid sheet having both an initial unfolded configuration patterned with slots and fold lines to define a perimeter base, an interior backrest and a shelf, and a subsequent folded configuration with the sheet folded at the fold lines to define the stand.

Abstract: A mobile, releasably attachable, white-board comprises a pad formed of polyurethane having a composition of polymer and catalyst to impart a tacky character to at least the inner surface so that the inner surface is capable of removable tacky attachment to a support surface without additional adhesive. A dry-erase sheet is affixed to the pad.
