Appl. No.:

12/033242

Inventors:

Daniel W. Loyer - San Clemente CA, US
Henry Roskos - Los Gatos CA, US
Bruce Hammond - Castro Valley CA, US

Assignee:

MVM Technologies, Inc. - San Clemente CA

International Classification:

B41J 2/045

US Classification:

347 72

Abstract:

A printhead or other droplet emitter is manufactured integrally with a flexible circuit. Preferred methods of manufacturing a droplet emitter comprise the steps of: creating metal traces, preferably deposited using a metal oxide precursor; patterning a sacrificial photoresist to create ink channels and nozzle chambers; depositing piezoelectrically active material over the metal traces and sacrificial photoresist; patterning vias through the piezo-electrically active material to act as nozzles and openings to ink reservoirs; and flushing out the photoresist. The piezo-electrically active material is preferably a mixture of PZT and PVDF.

International Classification:

H05K 1/00
B41J 2/015

US Classification:

347 20, 174254

Abstract:

Fine conductor lines (those having a width of ≦50 μM) are disposed on a flexible metal oxide containing substrate by masking portions of the substrate, and then surface metallizing unmasked portions of the substrate. Polymeric preceramic films are preferred, especially those having a glass temperature of at least 300 C. and those of the PZT family, or those containing BeO. All suitable reducing gasses are contemplated, including especially H2. All suitable masking materials are similarly contemplated, including especially titanium, titanium nitride, tungsten nitride, tantalum, and tantalum nitride. In especially preferred embodiments the conductor lines have a width of ≦25 μM, ≦15 μM, ≦5 μM, and even ≦1 μM. The lines can advantageously compose a circuit that is coupled to a piezoelectric or other mechanical actuator, which in turn can be fluidly coupled to a fluid reservoir.

Appl. No.:

12/473530

Inventors:

John MacKay - San Jose CA, US
Henry Roskos - Los Gatos CA, US

International Classification:

H01L 21/3205

US Classification:

438613, 257E21295

Abstract:

Methods of producing a solder bump are presented. Preferred methods lack a requirement for photoresist processing or masking a target substrate. Contemplated methods include forming a well around one or more bond pads on a wafer where the walls of the well are formed by a passivation layer material. Contact material can comprise a solder paste or an under bump metallization layer, which can be placed within the wells as a contact bed for solder balls. A priori prepared solder balls, in solid form or in molten form, can deposited on the contact material to produce the solder bump.

US Classification:

438613, 257E21295

Abstract:

Methods of producing a solder bump are presented. Preferred methods lack a requirement for masking a target substrate. Contemplated methods include forming a well around one or more bond pads on a wafer where the walls of the well are formed by a covering layer material, possibly comprising photoresist or passivation material. The well can be filled with a contact material. Contact material can comprise a solder paste or an under bump metallization layer, which can be placed within the wells as a contact bed for solder balls. A priori prepared solder balls, in solid form or in molten form, can deposited on the contact material to produce the solder bump.

Assignee:

MVM TECHNOLOGIES, INC. - San Clemente CA

International Classification:

H01F 41/04

US Classification:

296021

Abstract:

Methods of producing a solid state air core spiral inductor are presented. A spiral coil can be deposited on a substrate. One or more solder dams can be positioned on the coil where the dams comprise a well into which solder bumps can be attached to the coil. Material covering the coil or between the gaps the inductor's coil can be removed yielding an air core. Contemplated inductors can include one or more tap points.

Fredrick Quincy Johnson - Pleasanton CA, US

International Classification:

H01F 5/00

US Classification:

336200

Abstract:

Solid state components having an air core and methods of producing such components are presented. An air core component preferably has lower conducting bands, upper conducting, and conducting posts that collectively form a conducting coil. A coating material placed at least over the upper bands of the coil provides structural support for the coil. The coil can be built around or in a sacrificial core material that can be removed leaving an air core behind.

International Classification:

G01N 27/00
G01N 37/00

US Classification:

422 8203, 73 6143

Abstract:

An ion concentration meter measures a concentration of an ion in a solution by exposing both an ISFET gate and a reference electrode within a filtered test area. In preferred embodiments, the test area filters preferred compounds from a solution being tested by occluding an opening to the test area with a species-selective membrane. Contemplated species-selective membranes include silicate membranes, chalcogenide membranes, lanthanum fluoride membranes, and valinomycin membranes.

Abstract:

Systems, devices, and methods for administering healthcare to a user or patient based on analysis of user-specific respiratory and oximetry parameters is disclosed. Additional parameters specific to the user, the user's health condition, or the user's current or planned treatment are optionally included in the analysis. The user inputs parameter values on a healthcare monitoring device. The device communicates such values to a healthcare information hub, which pre-processes the values into data sets and forwards the data sets to a healthcare server. The hub performs preliminary analysis of the parameter values and provides a preliminary report to the user that indicates a characterization of the user's health condition (e.g., diagnosis, prognosis, suggested preliminary therapy regimen, etc) or whether further parameter values should be input. The healthcare server analyzes the datasets received from the information hub, optionally including additional data sets (e.g., environmental parameters local to the user, demographic data related to the user, the user's medical history, etc), and infers an instruction for the user. The instruction is relayed to the patient via the information hub and directs the patient to use the monitoring device to obtain further respiratory or oxygenation parameter values, follow a therapy regimen for the user's health condition, or various partial or complete combinations of both.
