  • Publication number: 20240120093
    Abstract: The present invention provides a novel approach for storing, analyzing, and/or accessing biological data in a cloud computing environment. Sequence data generated by a particular sequencing device may be uploaded to the cloud computing environment during a sequencing run, which reduces the on-site storage needs for the sequence data. Analysis of the data may also be performed in the cloud computing environment, and the instructions for such analysis may be set at the originating sequencing device. The sequence data in the cloud computing environment may be shared according to permissions. Further, the sequence data may be modified or annotated by authorized secondary users.

  • Patent number: 11025121
    Abstract: An electric motor includes a stator; an annular end cap, fastened at a first end of the stator; a threaded seat that is mounted at an outward end face of the annular end cap for receiving a first gas foil thrust bearing; a shaft, inserted through the stator, through the annular end cap, and through the threaded seat; a thrust runner mounted at an end of said shaft adjacent the threaded seat; a first gas foil thrust bearing that is mounted into the threaded seat, adjacent a face of the thrust runner facing the stator; a bearing cap that has a threaded fitting by which it is attached onto the threaded seat; and a second gas foil thrust bearing that is mounted into the bearing cap adjacent to a face of the thrust runner opposite the first gas foil thrust bearing.

  • Patent number: 10008898
    Abstract: An electric motor stator includes an armature surrounding a longitudinal opening for receiving a shaft, with longitudinal fins protruding from an outer surface of said armature; windings are wound within the armature and protruding beyond ends of the armature; and encapsulant seals the windings to the armature, such that the encapsulant serves as an outer housing for the windings.

  • Publication number: 20130129488
    Abstract: A high-speed blower designed to move and circulate dry process gas includes an axial or mixed-flow compressor driven by a brushless permanent magnet synchronous motor utilizing a remotely mounted variable frequency drive. The blower uses foil gas bearings which enable high-speed, low-power loss, and oil-free operation. The blower comprises an outer blower housing and an inner blower housing defining an annular cavity therebetween. A cooling flow of process gas may be leaked through the inner blower housing to cool the internal operational components of the blower, including the motor and the bearings, and to capture heat therefrom, which can be added to the process gas flow moving through the blower. Diffuser vanes and flow-straightening vanes are provided on the outer surface of the inner blower housing to improve the fluid dynamics of the process gas flow through the blower and heat transfer from the inner blower housing.
