Abstract: A multi-layer electrode for a capacitive pressure sensor is manufactured according to a method including co-extruding a conductive polymer layer and a dielectric foam layer and forming coextruded layers of the capacitive pressure sensor and pressure rolling an XY layer and the coextruded layers together and forming the multi-layer electrode.

Abstract: A catheter containment system configured for securing a proximal portion of a catheter placement system within a sterile field. This relieves the clinician from holding the proximal portion to prevent them for falling outside of the sterile field. Further, the proximal portion can be secured out of the way from the insertion site providing a clear field of view. Embodiments include a body, having a channel configured to releasably engage an extension leg or guidewire, and a securement feature to secure the body to a portion of a drape or similar item of the sterile field. Exemplary securement features can include clips, clasps, pins, magnetic elements, adhesives, twist ties, zip ties, snap fasteners, hook and loop attachments, mechanical grasping devices or adhesive pads. The system can further include anchor tabs that can be adhered to the drape to provide an anchor point.

Abstract: A multi-layer electrode of a capacitive pressure sensor is manufactured by roll to roll printing a conductive layer onto a polymer layer and forming a mutual capacitance sensor layer of the capacitive pressure sensor, co-extruding a conductive polymer layer and a foam dielectric layer and forming a coextruded layer of the capacitive pressure sensor, and pressure rolling the mutual capacitance sensor layer and the coextruded layer together and forming the multi-layer electrode. The conductive polymer layer includes between about 2 wt. % to about 15 wt. % graphene and between about 0.01 wt. % and 5 wt. % of the carbon nanotubes. Also, the conductive polymer layer has a flexural modulus equal to or greater than 5,000 MPa and an electrical resistivity less than or equal to 10 Ohm/mm3, and the polymer layer and/or the conductive polymer layer is formed from recycled polyethylene terephthalate.

Abstract: Rotational hardstop assemblies that provide greater than 360 degrees of non-continuous rotation for rotating mechanisms are provided. In certain embodiments, an assembly is used to provide 630 or more degrees of rotation for the shoulder axis of a robot, such as a wafer transfer robot. The rotational hardstop assemblies include opposing magnets as springs. According to various embodiments, the opposing magnets provide non-contact engagement and produce no contact noise nor have any wear over time. The rotational hardstop assemblies provide the ability to location from either direction of rotation of a robot cylindrical coordinate system.

Abstract: A lift fluid driven downhole electrical generator and method for generating and controlling the electrical output from the electrical generator is disclosed. The electrical generator comprises a housing having a lift fluid port in a sidewall portion thereof for allowing the flow of lift fluids therethrough. A rotor is rotatably disposed within the housing. The rotor converts lift fluid pressure to rotary motion when the lift fluid travels through the lift fluid port and impinges the rotor. The electrical generator also includes an electromagnetic assembly having a first portion that is rotatable with the rotor and a second portion that is stationary with the housing. The electromagnetic assembly converts the rotary motion to electricity as the first portion of an electromagnetic assembly rotates relative to the second portion of the electromagnetic assembly.
