International Classification:

G01D 15/00
H01L 21/00

US Classification:

216 27, 438 8

Abstract:

A method for improving fluidic flow for a microfluidic device having a through hole or slot therein. The method includes the steps of forming one or more openings through at least part of a thickness of a substrate from a first surface to an opposite second surface using a reactive ion etching process whereby an etch stop layer is applied to side wall surfaces in the one or more openings during alternating etching and passivating steps as the openings are etched through at least a portion of the substrate. Substantially all of the etch stop layer coating is removed from the side wall surfaces by treating the side wall surfaces using a method selected from chemical treatment and mechanical treatment, whereby a surface energy of the treated side wall surfaces is increased relative to a surface energy of the side wall surfaces containing the etch stop layer coating.

International Classification:

B67D 7/78

US Classification:

2224646, 347 1, 347 7, 347 84

Abstract:

A consumable supply item for an imaging device holds an initial or refillable volume of pigmented ink. Its housing defines an interior and a fluid exit port. Users orient the housing to deplete the ink in a downward direction. A float on a surface of the ink suspends an inlet opening of a fluid conduit tube underneath the surface. A height of the opening falls downward as the fluid depletes and the float drops. The tube draws a desired concentration of ink and supplies it to the exit port. The concentration is predetermined relative to an overall height of the fluid. The tube height remains proportional to the height of the fluid, increases/decreases proportionally, or other. The design overcomes settling. The design also avoids mechanical stirring and other complex sediment mixing techniques. Embodiments include float/tube arrangements and testing observations, to name a few.

International Classification:

B41J 2/175

US Classification:

347 86

Abstract:

A consumable supply item for an imaging device holds an initial or refillable volume of ink. A housing defines an interior having a pair of opposed electrodes. The electrodes have a capacitance that varies in response to an amount of liquid between them. A controller energizes one electrode and receives an output reading from the other. The controller processes the reading on board the housing and supplies it as a digital data stream to the imaging device during use. A memory stores calibration values for an empty and full housing. The controller writes back to the memory present fluid levels obtained from the output reading of the electrode. An enable output allows operation or not of a fluid pump in the imaging device. Materials, construction, modularity, and fluid communication ports are further embodiments, to name a few.

Appl. No.:

8/030758

Inventors:

Philip L. Roberts - New Orleans LA
Mark L. Doerre - Lexington KY

International Classification:

A61B 1732

US Classification:

606167

Abstract:

A retractable, disposable surgical knife that includes a hollow sheath and a blade assembly received for sliding movement within the hollow sheath. The blade assembly includes a slide block and a knife blade held by the slide block. A mechanism including a cooperating resilient actuator and guide track allows the blade assembly to be selectively secured in a first, retracted position wherein the blade is withdrawn into the sheath and a second, extended position wherein the blade extends from the sheath for use. A separate mechanism is provided for permanently locking the blade assembly in a third, fully retracted position wherein blade is fully withdrawn within the sheath to prevent inadvertent sticks. The permanent locking mechanism is fully concealed within the sheath so as to prevent inadvertent engagement with an object and possible release from the permanently locked position.
