Patent number: 10729011Abstract: A method of providing power input to a flexible printed circuit. The method involves the step of bisecting a flexible printed circuit into a first conductive area adapted for power input and a second conductive area adapted for ground connection. In accordance with this teaching, power input is provided to electrical components attached to the flexible printed circuit via first conductive area and second conductive area, rather than through individual control lines.Type: GrantFiled: August 21, 2019Date of Patent: July 28, 2020Assignee: TF Massif Technologies Ltd.Inventors: Alain Carel, Kimball Andersen

Publication number: 20200198045Abstract: A method of keeping a scriber tip clear of ablated material that uses an ablation scriber head constructed in accordance with the teachings of the method. The ablation scriber head directs pressurized gas at the scriber tip to keep the scriber tip clear of ablated material. It is preferred that the pressurized gas contains an oxidizing agent which oxidizes the ablated material.Type: ApplicationFiled: December 23, 2019Publication date: June 25, 2020Inventors: Alain CAREL, Kimball ANDERSEN

Patent number: 10462906Abstract: A flexible printed circuit is described that includes a flexible supporting substrate having a first face and a second face. A conductive material is deposited by vacuum deposition on at least one of the first face or the second face of the flexible supporting substrate. A flexible conductive circuit is formed on the conductive material by electrical discharge machining. The flexible conductive circuit defines a plurality of electrical component placement circuits to which electrical components may be attached. The flexible printed circuit can be rolled or folded. The flexible printed circuit can also be made in sizes much larger than is currently possible with other competing technologies.Type: GrantFiled: January 27, 2017Date of Patent: October 29, 2019Inventor: Alain Carel

Patent number: 7902114Abstract: Using zeolites as the active adsorbent, adsorbent laminates have been fabricated with various sheet supports. These adsorbent laminates have been successfully operated for oxygen enrichment at high PSA cycle frequencies, such as upwards of at least 150 cycles per minute. Methods for making suitable adsorbent laminates are described. The methods generally involve forming a slurry comprising a liquid suspending agent, an adsorbent and a binder. Laminates are made by applying the slurry to support material or admixing support material with the slurry. The slurry can be applied to support material using a variety of techniques, including roll coaters, split roll coaters, electrophoretic deposition, etc. One method for making laminates by mixing support material with the adsorbent slurry comprises depositing the slurry onto a foraminous wire, draining the slurry material, and pressing the material to form a ceramic adsorbent paper. Spacers can be formed on adsorbent laminates to space one laminate from another.Type: GrantFiled: October 22, 2007Date of Patent: March 8, 2011Assignee: Xebec Adsorption Inc.Inventors: Bowie G.

Publication number: 20060073272Abstract: A control panel and method of manufacturing a control panel that can be used with an electrically sensitive control device (e.g., a touch sensor, etc.) is disclosed. The control panel includes a substrate layer having a first surface and a second surface. A conductive coating is provided that is viewable from the first surface. The conductive coating defines at least one of a background area and a fill area. The background area is electrically isolated from the fill area. According to one embodiment, the background area and the fill area are both defined by the conductive coating.Type: ApplicationFiled: September 27, 2005Publication date: April 6, 2006Inventor: Alain Carel

Patent number: 6692626Abstract: Methods for forming adsorbent laminate structures particularly for use in pressure swing adsorption processes and devices are disclosed. One disclosed embodiment comprises providing a metal or alloy support and depositing adsorbent material onto the support by electrophoretic deposition. Adsorbent material also may be deposited on plural strips, which are then assembled into a laminate structure along the support. Adsorbers also are described comprising first and second wire mesh sheets having adsorbent material deposited on a first major planar surface thereof. The first and second sheets are placed adjacent one another and spaced sufficiently to define a flow channel. Another disclosed embodiment comprises plural wire mesh sheets having adsorbent material deposited on both first and second major opposed planar surfaces thereof, the sheets being spaced from each other to define a gas flow channel. The adsorber may include ventilation gaps to provide ventilation between flow channels.Type: GrantFiled: April 20, 2001Date of Patent: February 17, 2004Assignee: QuestAir Technologies Inc.Inventors: Bowie G.

Patent number: 6565635Abstract: Disclosed embodiments of the apparatus address the challenges of rotary PSA systems, both axial and radial flow, with M>1 by providing interpenetrating, layered manifolds to accommodate all of the steps of a complex PSA cycle, suitable with equal compactness for any value of “M”. This approach extends readily to accommodate a plurality of rotary PSA modules and their cooperating compression machinery within a single layered manifold assembly for a single PSA plant train. Described embodiments of the rotary PSA apparatus include stators that define fluid ports. In particular embodiments of the described apparatus, a second stator defines pressure swing adsorption cycle sectors, each sector being defined by a light product delivery port, light product withdrawal ports, and light reflux return ports. The adsorber elements may directly contact one or more of the stators in a fluidly sealing manner (i.e., have a clearance gap of from about 0 to about 50 microns) using described reinforced adsorbers.Type: GrantFiled: September 25, 2001Date of Patent: May 20, 2003Assignee: QuestAir Technologies, Inc.Inventors: Bowie G.
