Abstract: A system and method are presented relating to a hybrid portable charging device having an internal battery and an internal supercapacitor. Input logic is implemented as part of the management system for the charging device. In one embodiment, input power is analyzed to determine whether the input power level is low, medium, or high, with input power being diverted to the battery or supercapacitor depending on the determined input power level. At high input power, the supercapacitor is charged first. At low input power, the battery is charged first. At medium power, the input power is split between the supercapacitor and the battery. In another embodiment, output can be directed using output logic so that power flows first from the supercapacitor so that the supercapacitor is fully discharged before battery power is output to the load on the charging device.

Abstract: An antenna array assembly is described herein. The assembly includes a housing, a plurality of antennas arranged in an array, an antenna switcher in communication with the array and a tuner. The tuner is in communication with the antenna switcher. The tuner has a memory and a channel look-up table contained therein. The look-up table has a remembered association between an optimal signal associated with each channel of the tuner and one of the plurality of antennas. The tuner is configured to automatically select from the look-up table only one of the plurality of antennas that has detected the optimal signal associated with the channel. When that channel is selected by a user the tuner instructs the antenna switcher to switch to the single antenna that is detecting the optimal signal in accordance with the look-up table.

Abstract: Devices and methods disclosed herein can include an accessory mount having a first clamp and a second clamp each configured to grip an elongate member. The first clamp and the second clamp can include an open configuration and a clamped configuration. In the open configuration, a respective first end is disengaged from a respective second end for receiving the elongate member. In the clamped configuration, the first end and the second end are moved to grip the elongate member. A first portion of the elongate bridge can be coupled to the first clamp and a second portion of the elongate bridge can be coupled to the second clamp. An accessory interface can be coupled to the elongate bridge. The accessory can be positionable along the elongate bridge for alignment along the longitudinal direction of the elongate member.

Abstract: A mount for joining a base object to an ancillary object is provided. The mount includes a top layer, a bottom layer, a key, a lock and a collar. The top layer is engaged to the ancillary object and the key extends therefrom. The bottom layer is engaged to the base object. The lock is a recess defined by the bottom layer and has a shape complimentary to that of the key such that the lock and key are mechanically and removeably engaged to one another. The collar extends from a top end to a bottom end. The top end is fixedly engaged to the top layer and the bottom end is fixedly engaged to the bottom layer. The collar is disposed about the lock and the key. The mount may be configured for electrical and mechanical communication and may include an interface for communication with a camera hot shoe.

Abstract: A multi-mode microphone assembly includes a mono microphone, a stereo microphone, and a rotary switch contained within a housing. The mono microphone has a mono input/output mode and the stereo microphone has a stereo input/output mode. Only one input/output mode is active depending on the position of the rotary switch within the housing. When the rotary switch is in a first position only the mono input/output mode is activated and when the rotary switch is in a second position the mono input/output mode is deactivated and the stereo input/output mode is activated. The first position of the rotary switch corresponds to a first position of the housing. The second position of the rotary switch corresponds to a second position of the housing. The first and second positions of the housing are offset 180 degrees from one another.
