Abstract: A two-piece case for a smart phone or other electronic device includes a base and a frame. Interengaging snap coupling elements on the base and the frame releasably attach the components together to hold a phone within the case.

Abstract: An improved vibration motor controller and method maintains a substantially consistent vibration over time, despite decreasing battery voltage over time, with the controller used in a mobile communication device, the mobile communication device powered by a battery having a maximum charge voltage and a minimum charge voltage, the controller being operative for monitoring the available voltage at the battery; driving the vibration motor using pulse width modulation with a motor voltage which is less than the minimum charge voltage of the battery; and controlling the pulse width modulation used to drive the vibration motor in a manner to provide a substantially consistent power level despite fluctuations in voltage of the battery.

Abstract: A mobile device case comprising separate inner and outer layers, wherein the inner layer comprises a flexible form-fit bumper that protects an electronic device installed therein without significantly covering the front and back of the device, and wherein the outer layer comprises a form-fit shell that interfaces with the inner bumper and extends on at least one face of the device excluding the front of the device.

Abstract: A protective or decorative case for an electronic device includes at least a first shell portion and a second shell portion. The first and second shell portions each comprise at least one magnetic coupling element to provide for removably coupling the shells together in an assembled configuration to house an electronic device therein.

Abstract: A ruggedized case having a main cover to be fitted closely over a hand-held electronic device is tub-shaped and is open on one side thereof for receiving the device therein. The main cover includes a rigid tub and resilient portions on the inside and outside of the tub. A substantially rigid screen protector is provided for protecting the display and is closely fitted over a front face of the hand-held electronic device and is closely fitted within the ruggedized main cover and held firmly therein. Thus, resilient material is placed closely against the hand-held electronic device, the rigid protective portion is closely against the inner soft cushioning, and an outer layer of soft cushioning material is closely against the rigid protective portion. The rigid protective panel is sandwiched between elements of soft, cushioning material. This composite, cushion-first construction provides superior protection against mechanical shock.

Abstract: A case for an electronic device comprises one or more sound enhancement ports. The sound enhancement ports comprise a first opening oriented in a first direction, a second opening oriented in a second direction generally perpendicular or unaligned with the first direction, and a sound conduit between the first and second openings. An electronic device is inserted into the case and the sound enhancement ports are positioned to provide passive amplification or directional enhancement to sound waves.

Abstract: An electronic device protective cover that includes a substantially rigid screen protector panel. The electronic device cover attaches by snap-on connection over a portion of the electronic device. The protective cover can optionally secure to a base by a snap-on connection to form a multi-component protective system.
