  • Publication number: 20190376468
    Abstract: A Stirling cycle machine with a liquid fuel/gaseous fuel burner. The burner may include a preheater to capture the thermal energy of the exhaust. The burner directs the preheated air to each burner head, where it enters a prechamber. Each burner head includes a fuel nozzle that directs liquid or gaseous fuel into the prechamber. The prechamber is fluidically connected to a combustion chamber via a prechamber nozzle that has a smaller opening than the prechamber. The burner head ignites the fuel air mixture in the prechamber with an ignitor located above or within the prechamber. The flame is initially lit as a diffusion flame in the prechamber. The flame is pushed out of the prechamber into the combustion chamber by an increased air flow rate. The liquid fuel from the nozzle now evaporates in the prechamber and forms a prevaporized flame in the combustion chamber.

  • Publication number: 20190249657
    Abstract: A peristaltic pump and related-method are disclosed that includes a cam shaft having a plunger cam, a plunger-cam follower that engages the plunger cam of the cam shaft, a tube receiver, a spring, a plunger, a position sensor, and a processor. The tube receiver receives a tube. The spring provides a bias. The plunger is biased toward the tube by the spring and the plunger is to the plunger-cam follower, such that expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates actuates the plunger away from the tube. The position sensor determines a position of the plunger and the processor estimates fluid flow within the tube utilizing the position of the plunger.

  • Publication number: 20190219047
    Abstract: A peristaltic pump is disclosed that includes a plunger, a spring, an actuator, a position sensor, and a processor. The plunger actuates toward and away from a tube. The spring biases the plunger toward the tube. The actuator actuates the plunger away from the tube and mechanically engages and disengages from the plunger. The position sensor senses a position of the plunger. The processor receives the sensed position of the plunger and estimates fluid flow within the tube using a first position of the plunger when the actuator is engaged with the plunger and a second position of the plunger when the actuator is disengaged from the plunger.

  • Patent number: 10345208
    Abstract: A system and method for applying force to at least one device by setting a target position of a pin with respect to the device, setting a target force that the pin will apply to the device, moving the pin towards the device, stopping the movement of the pin when the first of a force exerted on the device by the pin substantially equals the target force, or a position of the pin substantially equals the target position happens, and modifying the position of the pin to maintain the force of the pin on the device at substantially constant.

  • Patent number: 10316834
    Abstract: A peristaltic pump includes a cam shaft, first and second pinch-valve cams, first and second pinch-valve cam followers, a plunger cam, a plunger-cam follower, a tube receiver, a spring-cam plunger, a position sensor, and a processor. The plunger cam is coupled to the cam shaft. The plunger-cam follower is configured to engage the plunger cam. The spring-biased plunger is coupled to the plunger-cam follower where expansion of the plunger cam along a radial angle intersecting the plunger-cam follower as the cam shaft rotates pushes the plunger cam to disengage the spring-biased plunger from the tube and a spring coupled to the spring-biased plunger biases the spring-biased plunger to apply the crushing force to the tube. The position sensor is operatively coupled to the spring-biased plunger and is configured to determine a position of the spring-biased plunger. The processor estimates fluid flow using the position.

  • Publication number: 20190170134
    Abstract: A peristaltic pump having at least first, second, and third stages is provided. The peristaltic pump includes a plunger, inlet and outlet valves, a spring, and an actuator. The plunger actuates toward and away from a tube, the inlet valve is upstream of the plunger, the outlet valve is downstream of the plunger, the spring biases the plunger toward the tube, and the actuator mechanically engages and disengages from the plunger. In the first stage, the inlet valve is opened and the plunger is actuated from the tube, in the second stage, the inlet valve is closed, the plunger is actuated toward the tube, and the actuator is mechanically disengaged from the plunger, and in the third stage, the outlet valve is opened. In the third stage or in a fourth stage, the actuator actuates the plunger toward the tube to discharge fluid downstream past the outlet valve.

  • Patent number: 10299941
    Abstract: A prosthetic arm apparatus comprising a plurality of interconnected segments that provide the prosthetic arm apparatus with substantially the same movement capability and function as a human arm. The segments are connected to one another and connectable to a harness mount that may be adorned by the user. Each segment of the plurality of segments includes an actuator providing a portion of the movement capability, and each segment may operate independently of each of the other segments of the plurality of segments. One segment of the plurality of segments includes a non-backdriving clutch that transfers power from the actuator to an output interface of the segment when the actuator is actuated to generate movement of the output interface in either of two opposing directions and prevents backward transfer of power from the output interface to the actuator of the segment in both of the two opposing directions.
