  • Patent number: 11919605
    Abstract: The present invention is directed towards a disk braking system for a bicycle having a rear disk coupled to a rear wheel. A rear brake caliper is coupled to a rear brake lever and the rear brake caliper is also coupled to a hydraulic actuator which has a piston that slides within a cylinder filled with hydraulic fluid and hydraulic tubing coupled to the cylinder and a front brake. When the rear wheel and rear disk are rotating, the rear brake caliper can be actuated which causes compresses rear brake caliper against the rear disk to slow the rotation of the rear wheel. The movement of the rear brake caliper can actuate the hydraulic actuator which causes hydraulic fluid to flow through the hydraulic tubing to actuate a front brake.

  • Patent number: 11866124
    Abstract: A braking system includes a vehicle having a front brake and a rear brake. The system includes a moveable structure connected to a rear brake. The rear brake may be a hydraulic brake. When the rear brake is actuated, the moveable structure moves. The movement of the structure pressurizes hydraulic fluid in a tube which actuates a front hydraulic brake.

  • Publication number: 20200383620
    Abstract: Systems and method are disclosed for determining a concentration of an analyte in a fluid (e.g., blood). The system can draw blood from a patient and deliver the blood to a sample cell. A particular component of the fluid (e.g., plasma) may be separated and/or positioned such that the concentration of the analyte is measured in the particular component of the fluid (e.g., plasma). The sample cell can include a sample container that has two window pieces. The system can have a fluid passage having a tip configured to mate with a multi-lumen catheter without leaking. The multi-lumen catheter can have proximal and distal ports. A fluid pressure system can be configured to periodically draw fluid from vasculature through a proximal intravascular opening and the proximal port while maintaining a low pressure and/or flow rate to thereby reduce risk of reversing the fluid flow in a vessel and drawing infusates upstream into another intravascular opening.

  • Publication number: 20200178869
    Abstract: A fluid handling system for use in bodily fluid analysis. The system comprises a first fluid handling module configured to interface with a main instrument. The first fluid handling module has a first fluid handling network and the first fluid handling network includes an infusate passage and an infusion fluid pressure member suitable for moving fluid within the infusate passage. The fluid handling system also has a second fluid handling module separate from the first module which is configured to interface with the main instrument. The second fluid handling module has a second fluid handling network and at least one sample analysis cell which is accessible via the second fluid handling network. The first and second modules are configured to interconnect and provide fluid communication between the first and second fluid handling network and the sample cells.

  • Patent number: 10466156
    Abstract: A method is provided for transporting a plurality of cells through a flow chamber, wherein the cells are initially immobilized on an internal surface of the flow chamber. The method comprises: selectively releasing the cells from the internal surface of the flow chamber; and flowing liquid through the flow chamber such that the released cells travel with the liquid, thereby transporting the cells through the flow chamber. Cells can be immobilized on or selectively released from the internal surface by applying or removing a trapping potential. The trapping potential can arise from an electric field gradient or an optical field gradient. Alternatively, cells can be selectively released from the surface using photocatalysis. Selective release allows cells to be individually observed or analyzed downstream, and can be based on a signal detected from one or more cells immobilized on the surface.

  • Patent number: 10252770
    Abstract: A braking system includes a moveable structure connected to a rear brake. The rear brake may be a hub brake or a disc brake. A cable to the front brake is connected to the moveable structure. When the rear brake is actuated, the moveable structure moves. The movement of the structure pulls the cable to actuate the front brake. The movement may include a translation, rotation, or both.
