  • Publication number: 20240291268
    Abstract: Process control instruments having local intrinsic safety barriers and methods of manufacturing the same are disclosed. An example field instrument for a process control assembly includes a non-protection compartment, intrinsically safe circuitry positioned in the non-protection compartment, a protection compartment, non-intrinsically safe circuitry positioned in the protection compartment, and local barrier circuitry positioned in the protection compartment to operatively couple the non-intrinsically safe circuitry to the intrinsically safe circuitry, the local barrier circuitry to prevent the intrinsically safe circuitry from receiving an electrical energy that is greater than an electrical energy threshold from the non-intrinsically safe circuitry.

  • Publication number: 20240197347
    Abstract: Devices for the disruption and/or removal of obstructive material in a blood vessel. The device can comprise an elongated shaft having a proximal portion, a distal portion, and a lumen extending therebetween. The device can further comprise a capture structure carried by the distal portion of the elongated shaft and having a greater cross-sectional dimension than a cross-sectional dimension of the elongated shaft. The capture structure can comprise an opening at a first end portion that is fluidly coupled to the lumen of the elongated shaft, a fluid impermeable sidewall enclosing an interior region, and an opening extending through a thickness of the sidewall. A portion of the sidewall surrounding the opening can be configured to deform towards or away from the interior region such that a cross-sectional dimension of the opening increases to receive the obstructive material therethrough.

  • Patent number: 11820153
    Abstract: In one example, a single valve assembly having multiple bi-stable cam actuated valves each to open and close a corresponding one of multiple separate liquid flow channels. In one example, a liquid recovery system for an inkjet type dispenser includes a reservoir, an interconnect to connect to a removable container, a flow channel from the reservoir to a printhead unit and back to the reservoir and from the reservoir to the interconnect, a pump to pump ink from the reservoir along the flow channel, and a bi-stable cam actuated valve to open and close the flow channel downstream from the pump between the reservoir and the interconnect.

  • Patent number: 10464333
    Abstract: A fluid supply integration module in a fluid dispensing device includes an on-board reservoir to store fluid, and a fluid interconnect to fluidically couple an external fluid supply container to the on-board reservoir. The fluid supply integration module includes a check valve system disposed between the on-board reservoir and the fluid interconnect. The check valve system includes a first check valve to permit fluid to flow in a first direction and a second check valve to permit air to flow in a second direction opposite the first direction.

  • Publication number: 20180221161
    Abstract: A joint prosthesis is provided that includes a proximal implant for attachment to a first portion of skeletal anatomy, the proximal implant including a proximal bone attachment portion and a distal cup portion. The prosthesis also includes a distal implant for attachment to a second portion of skeletal anatomy, the distal implant including a distal bone attachment portion and a proximal cup portion. An inter-joint element is located between the distal cup and the proximal cup. The inter-joint element includes surface portions shaped to complement said cups and is preferably formed as an ovoid. Each of the proximal implant, distal implant and inter-joint element include magnetic regions whereby the inter-joint element is attracted to both the proximal cup portion and to the distal cup portion to thereby provide stability across a large angular motion.
