Abstract: A carrier includes main body, a conductive elastic element, and a handle. The main body is adapted to carrying an electronic device and has a cavity. The conductive elastic element is disposed in the cavity. The handle is pivotally coupled to the main body. When the handle locks the main body to be located in a lock position, the handle exerts force on the conductive elastic element such that the conductive elastic element protrudes outside the main body through the cavity. When the handle does not lock the main body and exert force on the conductive elastic element to be located at a release position, the conductive elastic element is located inside the main body where it does not interfere with an outside device. This allows convenient insertion and removal of the carrier relative to a cage. Accordingly, the conductive elastic element is not damaged easily.

Abstract: A environmental reproduction system multiplexes information from a variety of sources to reproduce a target environment having visual and/or auditory impediments. The visual impediments may include one or more environmental conditions, such as rain, sleet, snow, darkness, brightness, or any other type of environmental condition. The auditory impediments may include loud noises, such as construction noises, or sounds that are too low, such as an emergency vehicle sound not being heard. The environmental reproduction system may determine the environmental condition from one or more sources, such as an internal microphone, an external microphone, temperature sensor, a camera, a weather receiver, or other types of sensors. The environmental reproduction may be in communication with an environmental condition database and operative to apply a signal processing action to a recording (video and/or audio recording) of the target environment based on the determined environmental condition.
