Abstract: An LED display module having features for improvement over prior art devices by providing novel features for improved LED visibility, improved weather and climatological sealing, improved electromagnetic interference (EMI) suppression, improved heat dissipation, and improved airflow.

Abstract: A hydraulically operated actuator is provided for controlling a roll of a vehicle that includes an actuator connected between a first mass and a second mass of the vehicle. An upper mount assembly is coupled to the first mass and a lower mount assembly is coupled to the second mass. A high-pressure chamber is disposed between the lower mount assembly and the upper mount assembly. The high-pressure chamber has a variable volume of hydraulic fluid disposed therein for selectively restricting the movement between the upper mount assembly and the lower mount assembly. A low-pressure accumulator includes a portal for receiving hydraulic fluid from the high-pressure chamber.

Abstract: A refrigeration system having a container with at least two different temperature cooling zones separated by a divider. The divider has a wall and a partition spaced apart from each other. The partition has a heat transfer plate with a sheet with a heat transfer substance attached thereto. The refrigeration system may be cooled by a variable capacity compressor system having refrigeration and hot-gas defrost modes. The system is defrosted by circulation of gas therethrough. A controller may be engaged to and selectably operate the compressor system.
