Abstract:
A method of fabricating an electrochemical energy storage cell such as a battery or supercapacitor involves positioning a portion of a fiber optic cable that includes at least one optical fiber sensor over a current collector layer. The electrode material of the energy storage cell is deposited over the current collector layer and the fiber optic cable.
Abstract:
An inkjet printhead includes an oleophobic membrane arranged at a location that allows the oleophobic membrane to simultaneously vent air from an ink flow channel of the printhead and to retain ink within the ink flow channel. The oleophobic membrane includes a metal structure having a nanostructured surface and low-surface energy coating disposed on the metal structure.
Abstract:
Approaches to remove bubbles from ink in an ink jet printer are described. Bubble removal may be implemented using a membrane disposed along an ink flow path. The membrane includes first and second component membranes having first and second coefficients of thermal expansion. The membrane is configured to, in response to a change in ink temperature, mechanically displace as a function of temperature due to a difference in the thermal coefficients of expansion of the first and second component membranes. The mechanical displacement of the membrane causes a volumetric change in a portion of the ink flow path.
Abstract:
An apparatus includes an inkjet manifold with at least one ink supply port coupled to an ink supply and at least one ink delivery port. A flow path is between the ink supply and ink delivery ports, and the flow path includes a trap configured to collect particle contaminants in response to a pulsed cleaning flow and hold the particle contaminants during an operational flow.

Abstract:
Approaches to remove objects from ink in an ink jet printer are described. An object separator for an ink jet printer includes one or more inlets configured to allow passage of ink that includes objects such as bubbles and particles into the object separator. The object separator has a number of stacked plates. Some of the plates have curved channels which are connected through other plates that include vias. The plates are arranged to form at least one cyclonic flow generator, the cyclonic flow generator configured to focus the objects into one or more focused flow streams. The object separator includes one or more object outlets that allow objects to exit the object separator and at least one ink outlet that allows the ink to exit the object separator.
Abstract:
Approaches to remove bubbles from ink in an ink jet printer are described. Bubble removal may be implemented using at least one temperature dependent element disposed along an ink flow path. The temperature dependent element is configured to change shape responsive to a change in ink temperature. The change in shape causes a volumetric change in a portion of the ink flow channel.

Abstract:
A battery has a lithium anode, a separator adjacent the anode, and a cathode adjacent the separator opposite the anode, the cathode comprising interdigitated stripes of a first and second material, wherein the first material contains sulfur and the second material comprises a solid electrolyte.
