Abstract: An adapter is disclosed herein. The adapter comprises a base, at least one retention element, a biased latch, a handle, and a switch. The base has a first surface and a second surface opposite the first surface. The first base surface is configured to receive a first surface of a mobile computing device. The at least one retention element is positioned on a front end of the base and is configured to receive a first end of the mobile computing device. The biased latch is positioned on a rear end of the base and is adapted to attach a second end of the mobile computing device. The handle is positioned on the second base surface and the switch is positioned on the second base surface adjacent to the handle. The switch is mechanically linked to the biased latch, and the biased latch is configured to release the mobile computing device from the base when the switch is actuated.

Abstract: An accessory configuration for enhancing wireless signal reception of a user device. The accessory, for the user device, may include a housing configured to receive the user device within a cavity; and a radiation element integrated with the housing and configured to affect a radiation pattern of an antenna of the user device that is configured to communicate a signal. The length of the radiation element may be based on a wavelength of the signal. The radiation element may be disposed within a predetermined distance of a zone of the cavity that is configured to receive a portion of the user device that includes the antenna when the user device is installed within the cavity.

Abstract: A driving circuit and lighting equipment using the same are provided. The driving circuit includes a first power receiving terminal, a second power receiving terminal and a power conversion unit. The first power receiving terminal receives an alternating current (AC) input signal. The second power receiving terminal is electrically coupled to a predetermined potential. The power conversion unit is electrically coupled to the first and second power receiving terminals for transforming the AC input signal into corresponding two AC output signals of different phases, wherein the two AC output signals are with the same current.
