A time-optimal trajectory generation method, for a robotic manipulator haying a transport path with at least one path segment, comprising generating a forward time-optimal trajectory of the manipulator along the at least one path segment from a start point of the at least one path segment towards an end point of the at least one path segment, generating a reverse time-optimal trajectory of the manipulator along the at least one path segment from the end point towards the start point of the at least one path segment, and combining the time-optimal forward and reverse trajectories to obtain a complete time optimal trajectory, where the forward and reverse trajectories of the at least one path segment are blended together with a smoothing bridge joining the time-optimal forward and reverse trajectories in a position-velocity reference frame with substantially no discontinuity between the time-optimal forward and reverse trajectories.

A configurable cryogenic storage device has a freezer and a rack carrier positioned inside of the freezer. The freezer includes a bearing and a drive shaft though the freezer, the drive shaft being coupled to the rack carrier inside the freezer and adapted to be coupled to a motor assembly. The rack carrier rests on the bearing in a manual rotation configuration and hangs from the drive shaft when the motor is connected. Coupling the drive shaft to the motor assembly lifts the rack carrier and decouples the bearing and enables automated rotation of the rack carrier by the motor. The rack carrier includes rack-mounting features holding a plurality of sample storage racks. The sample storage racks hang from the rack carrier and the rack-mounting features precisely position the end of each sample storage rack.

An automated cryogenic storage system includes a freezer and an automation system to provide automated transfer of samples to and from the freezer. The freezer includes a bearing and a drive shaft though the freezer, the drive shaft being coupled to a rack carrier inside the freezer and adapted to be coupled to a motor. The automation module includes a rack puller that is automatically positioned above an access port of the freezer. The rack puller engages with a sample rack within the freezer, and elevates the rack into an insulating sleeve external to the freezer. From the insulating sleeve, samples can be added to and removed from the sample rack before it is returned to the freezer.

A cryopump comprises a refrigerator, a condensing array cooled by the refrigerator, a radiation shield surrounding the condensing array and cooled by the refrigerator. The radiation shield has a frontal opening covered by a frontal array that is also cooled by the refrigerator. The frontal array comprises louvers across an otherwise substantially open center region of the frontal opening and an orifice plate across an outer region of the frontal opening. The hybrid frontal array allows for pumping speeds approximating those of a louver frontal array but with flow control comparable to an orifice plate.

A helium management control system for controlling the helium refrigerant supply from a common manifold supplies cryogenic refrigerators with an appropriate helium supply. The system employs sensors to monitor and regulate the overall refrigerant supply to deliver an appropriate refrigerant supply to each of the cryogenic refrigerators depending on the computed aggregate cooling demand of all of the cryogenic refrigerators. An appropriate supply of helium is distributed to each cryopump by sensing excess and sparse helium and redistributing refrigerant accordingly. If the total refrigeration supply exceeds the demand, or consumption, excess refrigerant is directed to cryogenic refrigerators which can utilize the excess helium to complete a current cooling function more quickly. If the total refrigeration demand exceeds the total refrigeration supply, the refrigerant supply to some or all of the cryogenic refrigerators will be reduced accordingly so that detrimental or slowing effects are minimized based upon the current cooling function.
