Abstract: A sprinkler for a fire suppression system includes a body defining an inlet and an outlet fluidly coupled to one another, a frame assembly including a frame member coupled to the body and extending away from the outlet, a deflector coupled to the frame member and offset from the outlet, a seal assembly configured to sealingly engage the body to prevent flow through the outlet, and a trigger assembly. The trigger assembly includes a shape memory alloy element configured to deform from an unactuated configuration to an actuated configuration in response to reaching an activation temperature. In the unactuated configuration, the trigger assembly directly engages both the frame assembly and the seal assembly and holds the seal assembly in sealed engagement with the body. In the actuated configuration, the trigger assembly permits the seal assembly to disengage from the body.

Abstract: An actuator system includes a shaft hub having a shaft and one or more rotation arms coupled to the shaft, one or more shape memory alloy springs coupled to the one or more rotation arms, and as a voltage source configured to apply a voltage to the one or more shape memory alloy springs. The voltage causes the one or more shape memory alloy springs to change in size or shape, thereby applying a force to the one or more rotation arms and causing the shaft hub to rotate. The actuator system also includes a processing circuit configured to receive an indication of a desired incremental rotation for the shaft hub and apply a voltage corresponding to the desired incremental rotation to the one or more shape memory alloy springs, causing the shaft and the shaft hub to rotate about a central axis.

Abstract: A damper assembly includes one or more dampers configured to regulate air flow through the damper assembly and an actuator system configured to move the one or more dampers between an open position and a closed position. The actuator system includes a contraction component coupled to the one or more dampers and comprising a shape memory alloy material. The actuator system further includes a first connector attached to a first end of the contraction component and a second connector attached to a second end of the contraction component. The first connector and the second connector are electrically isolated from the one or more dampers. The contraction component is configured to contract in response to an electric current being applied to at least one of the first connector and the second connector, thereby moving the one or more dampers to the closed position.

Abstract: A refrigeration control unit configured to modify an operating condition of a refrigeration unit is provided. The refrigeration control unit includes a first device housing component and a second device housing component defining a main refrigeration control device. The refrigeration control unit further includes a user interface component. The user interface component includes multiple controls configured to permit selection of multiple refrigeration unit operating parameters and a display. The user interface component is configured to be detachably coupled to the main refrigeration control device such that the user interface component is operational both when mounted in the main refrigeration control device and when mounted at a location remote to the main refrigeration control device.
