Abstract: A mobile device includes a panel audio loudspeaker including a display panel and an actuator coupled to the display panel. The mobile device includes a temperature sensor arranged to sense a temperature of the display panel, and an electronic control module in communication with the actuator and the temperature sensor. The electronic control module is programmed to perform operations including: obtaining, from the temperature sensor, data indicating a temperature of the display panel; and based on the data indicating the temperature of the display panel, adjusting a power signal provided to the actuator to drive the panel audio loudspeaker. The power signal can be adjusted by selecting, based on the data indicating the temperature of the display panel, a target temperature of the display panel; mapping the target temperature to a target power level; and changing the power signal provided to the actuator to the target power level.

Abstract: A chassis conversion device including an elongated frame with a pair of ISO corner castings affixed to each of its front and rear ends. A pair of twist locks is affixed to each of the front and rear ends of the frame. An additional two pairs of twist locks are affixed to the frame adjacent its midpoint. The latter two pairs of twist locks are selectively retractable so that they may be lowered beneath the top of the frame. In use, the chassis conversion device may be positioned atop a gooseneck-type chassis to permit the chassis to carry either one full-length (40′) ISO container or a pair of half-length (20′) ISO containers.
