  • SYSTEMS AND METHODS FOR OPTICAL FIBER CLEANING AND INTERFACE PARTICLE REDUCTION
    Publication number: 20240118500
    Abstract: A system comprises an optical fiber, a manipulator assembly, and a control unit. The manipulator assembly comprises a chassis, an optical fiber cleaning assembly housed within the chassis, and a drive mechanism housed within the chassis. The optical fiber cleaning assembly comprises a cleaning tape, a first spool on which the cleaning tape is wound, and a second spool onto which the cleaning tape is drawn after use. The drive mechanism is configured to advance the cleaning tape from the first spool to the second spool such that a portion of the cleaning tape wipes a face of the optical fiber. The control unit is configured to control the drive mechanism to advance the cleaning tape.

  • Vacuum pump systems for prosthetic limbs and methods of using the same
    Patent number: 11877938
    Abstract: Pump systems for use in suspension of a prosthetic device from a residual limb and methods of suspending a prosthetic device from a residual limb are disclosed. The pump systems include a mechanically activated pump having a first compression member coupled to a second compression member, a diaphragm disposed between the first and second compression members, and coupling elements that engage and couple together the first and second compression members. The mechanically activated pump may be connected with an electrically activated pump, forming a hybrid pump system to provide vacuum engagement between a prosthetic device and a residual limb.
