Abstract: A workstation is described for mounting specimens into a cryotransfer holder at cryogenic temperature. The workstation allows rotation about the cryotransfer holder axis to improve access to the sample placement area on the holder and to facilitate easy removal and retrieval of the sample after imaging. The cryotransfer holder includes a cylindrical dewar configured to maintain a constant center of mass about the holder axis regardless of orientation of the dewar.

Abstract: A terminal tractor includes a fifth wheel coupling which is rotatable relative to a longitudinal axis of the terminal tractor such that an opening in the fifth wheel coupling may be reoriented depending on the terminal tractor's direction of approach to a semi-trailer.

Abstract: A terminal tractor includes four independently steerable wheels, each with their own dedicated drive motor and each with their own dedicated steering device. The terminal tractor includes a controller operable to provide input commands to the drive motors and to the steering devices to operate the terminal tractor. The terminal tractor also includes a fifth wheel coupling which includes a lifting mechanism capable of raising and lowering the fifth wheel coupling a in single vertical direction.

Abstract: A cryotransfer holder for mounting a specimen held at cryogenic temperature in an electron microscope is described. The holder includes a cylindrical dewar configured to maintain a constant center of mass about the holder axis regardless of orientation of the dewar. The holder further includes a sample shutter control mechanism that can be decoupled from the shutter to reduce vibration during imaging. There is also described a workstation for mounting specimens into the cryotransfer holder at cryogenic temperature. The workstation allows rotation about the cryotransfer holder axis to improve access to the sample placement area on the holder and to facilitate easy removal and retrieval of the sample after imaging.

Abstract: A track lighting apparatus includes a frame, a power distributor, and an electrical interface. The frame includes a track configured to support a plurality of light fixtures. The power distributor electrically connects two or more inputs to two or more supply channels. Each supply channel is electrically insulated from other supply channels. The electrical interface includes electrical components that form two or more supply channels such that the supply channels form an incomplete series circuit that includes two or more breaks. A light fixture or a jumper is electrically connected across each break to complete the series circuits.
