Patent number: 10173365Abstract: The disclosed spray deposition systems and methods use spray charging and discharging techniques to assist with digital deposition of spray droplets on a substrate. For example, the disclosed systems and methods have a charging system that generates spray droplets from a spray generator and charges the droplets. Focusing electrodes help to collimate the droplets into a tight droplet stream and, optionally, steering electrodes help direct the tight droplet stream. A charge removal system neutralizes or removes the charge from the droplets, either during the deposition of the droplets on a substrate or after the droplets have been deposited on a substrate.Type: GrantFiled: December 20, 2017Date of Patent: January 8, 2019Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: John Steven Paschkewitz, Eric Shrader, Victor Beck

Patent number: 9314948Abstract: A system and method are provided for using magnetic elements to secure thin wires precisely in an injection molding process in a manner that matches a three-dimensional shape of the an injection molded product produced by the injection molding (overmolding) process. The thin wires are substantially immobilized in a manner that is designed to generally overcome the tendency of the thin wires, which have little mechanical strength, to normally deflect during an injection molding process by employing the magnetic forces produced by embedded magnets. Magnets are integrated into either the cavity or core of a mold structure and the thin wires are placed on those magnets to keep the wires in place during an injection molding process that allows the thin wires to be overmolded. A balance of the core and/or cavity of the mold will be formed of a non-magnetic material.Type: GrantFiled: November 2, 2012Date of Patent: April 19, 2016Assignee: Palo Alto Research Center IncorporatedInventors: David Johnson, Eric Shrader

Publication number: 20140193929Abstract: A low-cost integrated reflector and heat spreader for high-density high power solid-state (e.g., LED) lighting arrays includes a base structure onto which is applied a sacrificial material. A relatively thick thermal spray coating is applied over the base structure and sacrificial material. The sacrificial material is removed. A channel(s) is thereby provided within the thermal spray coating layer and in physical contact with the base structure. The channel may be filled with a cooling fluid. A pulsating heat pipe heat spreader may thereby be provided. A reflective material may be provided either over another surface of the base structure or alternatively over the thermal spray coating layer to provide a surface for reflecting and directing light emitted from a solid state light source that may be secured to the integrated reflector and heat spreader.Type: ApplicationFiled: December 9, 2013Publication date: July 10, 2014Applicant: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: John S.

Patent number: 8695687Abstract: A hybrid pin-fin micro heat pipe heat sink consists of a plurality of heat pipes secured to a base. The heat pipes have a generally hollow cross-section which transitions from a first cross-sectional shape (e.g., circular) to a second cross-sectional shape (e.g., triangular). A heat transfer medium (e.g., saturated steam) is sealed within the heat pipes. Cooling plates may be disposed over the base with the heat pipes in physical contact with and passing through the cooling plates. The method of manufacturing the heat pipes consists of passing a heat transfer medium through a pipe section having a first cross-sectional shape while transitioning to a second cross-sectional shape (e.g., by way of a rolling die press), then crimping the ends closed to seal the heat transfer medium therein.Type: GrantFiled: December 10, 2010Date of Patent: April 15, 2014Assignee: Palo Alto Research Center IncorporatedInventors: John S.

Patent number: 8551556Abstract: High aspect ratio structures can be obtained by print-patterning masking features in feature stacks such that each feature has a lateral edge which is aligned in a plane roughly perpendicular to the plane of the substrate on which the features are formed. Due to the differential lateral spreading between features formed on a substrate and formed atop other features, the print head is indexed less than the radius of a droplet to a position where a droplet ejected by the print head forms an upper feature atop a lower feature such that the lateral edges of the upper and lower features are aligned in the plane roughly perpendicular to the plane of the substrate. Feature stacks of two or more features may provide a vertical (or re-entrant) sidewall mask for formation of high aspect ratio structures, by e.g., electroplating, etc.Type: GrantFiled: November 20, 2007Date of Patent: October 8, 2013Assignee: Palo Alto Research Center IncorporatedInventors: Eric Shrader, Uma Srinivasan, Clark Crawford, Scott Limb

Patent number: 7955783Abstract: A method for masking regions of photoresist in the manufacture of a soldermask for printed circuit boards is disclosed. Following application of photoresist over patterned traces on a substrate, a sheet-like thin film is applied over the photosensitive material. The thin film may adhere to the photosensitive material by way of the adhesive state of the photosensitive material or by way of an adhesive applied to the photosensitive material or the thin film or carried by the thin film. Digital mask printing may proceed on the surface of the thin film. The photosensitive material may then be exposed through the printed photomask, the thin film (with photomask) removed, and the photosensitive material developed.Type: GrantFiled: November 9, 2007Date of Patent: June 7, 2011Assignee: Palo Alto Research Center IncorporatedInventors: Eric Shrader, Uma Srinivasan, Clark Crawford, Scott Limb

Patent number: 7811741Abstract: An image-forming medium and methods for forming and imaging the medium are provided. The disclosed medium can be strongly colored under room illumination (or deliberate UV) and can be selectively discolored at an appropriate light wavelength to form an image. In one embodiment, the image-forming medium can include a substrate (e.g., a sheet of paper), a photochromic material incorporated with the substrate, and a photo-absorbing material incorporated with the photochromic material. Exemplary methods for using the image-forming medium to make a transient image can include first forming the image-forming medium by applying a coating solution containing photochromic material to the substrate or paper. The image-forming medium can have a medium color and can then be selectively exposed to a radiation through a mask to convert the photochromic material from a colored form to a colorless form and thus to form an image having a color contrast with its background.Type: GrantFiled: February 24, 2009Date of Patent: October 12, 2010Assignee: Xerox CorporationInventors: Peter M. Kazmaier, Eric Shrader, Kentaro Morimitsu, Tyler Norsten, Gabriel Iftime, Fazilia Seker, Naveen Chopra
