Abstract: A protective and/or ornamental case for a foldable handheld electronic device. The case includes a front shell and a back shell pivotally connected to a hinge cover by one or more coupling mechanisms. A first portion of an electronic device is inserted into the front shell and a second portion of the electronic device is inserted into the back shell. The coupling mechanisms retain the front and back shells operatively engaged with the hinge cover as the electronic device housed in the case is pivotally or hingedly opened and closed, help prevent unintended opening or closing of the device, and keep the device open or closed when so positioned by a user.

Abstract: An antenna positioner, and methods of positioning using the antenna positioner, that may track a satellite are described. An antenna positioner may include a base and a mount rotatably coupled to the base to turn the mount about an azimuth axis. The mount may support an antenna element so that the antenna element can rotate about the elevation axis with respect to the mount. A center drive shaft for the elevation drive may pass through the hollow portion of the mount along the azimuth axis to drive a bevel gear set, a first gear of the set being coupled to the drive shaft and a second gear of the set being coupled to the antenna element, to rotate the antenna element about the elevation axis. Drive compensation is provided to counteract elevation rotation resulting from cross-coupling of the azimuth and elevation axes by the bevel gear set during azimuth rotation.
