Abstract: A trailer includes a housing including an internal frame and an external frame. The external frame is coupled to the internal frame. In certain embodiments, the internal frame is positioned between interior panels and exterior panels of the housing. In certain embodiments, the external frame is spaced from exterior panels.

Abstract: An electrically small antenna operable in both single-ended and differential antenna systems, and corresponding circuitry configurations, is provided. The antenna may be arranged on or in a wearable audio device, such as an earbud. The antenna may include a first curved arm electrically coupled to a first port. The antenna may include a second curved arm of equal size and equal shape as the first curved arm and electrically coupled to a second port. The second curved arm may be rotationally positioned 180 degrees, relative to the first curved arm, about an imaginary axis perpendicular to a surface of the wearable audio device. The single-ended antenna system may include a radio frequency integrated circuit (“RFIC”), fixed matching network, a tuneable capacitor, and a switching circuit. The differential antenna system may include an RFIC, fixed matching network, a tuneable capacitor, and a balun.

Abstract: An antenna assembly includes a radio frequency (RF) connector connected to a first end of a coaxial cable and a wire antenna attached to a second end of the coaxial cable. The wire antenna may be made of a shape memory alloy, such as nitinol. Examples of RF connectors include U.FL, IFEX, WAX, IPX, AMC, MHF and UMCC connectors that allow the wire antenna to be removably attached to a printed circuit board (PCB) of a lighting control device and to avoid hardwiring the antenna to the PCB. The device that includes the antenna assembly may be incorporated into a luminaire for wireless control of the luminaire. The lighting control device may be installed within the luminaire, such that the wire antenna is positioned between a light source and a diffuser. A number of such luminaires may be combined to provide an intelligent lighting system.

Abstract: Examples of methods and devices provide a charge level indication of a removable power source of a lighting control device. An example method may include receiving an input indication. A duration of the input is measured. If the measured duration exceeds a predetermined input duration threshold, an indication of a charge level of a removable power supply is obtained. The obtained charge level indication is compared, by a control unit, to a threshold charge level of the power supply. The threshold charge level is indicates an amount of charge remaining in the power supply. In response to a comparison result, an indicator light signal is applied to an indicator light. An example device may include a removable electrical power supply, an input device, an indicator light, and a control unit all of which may cooperate to perform a disclosed method.
