US Classification:

428702, 428689, 428640, 427250

Abstract:

Metal oxide thin films and production thereof are disclosed. An exemplary method of producing a metal oxide thin film may comprise introducing at least two metallic elements and oxygen into a process chamber to form a metal oxide. The method may also comprise depositing the metal oxide on a substrate in the process chamber. The method may also comprise simultaneously controlling a ratio of the at least two metallic elements and a stoichiometry of the oxygen during deposition. Exemplary amorphous metal oxide thin films produced according to the methods herein may exhibit highly transparent properties, highly conductive properties, and/or other opto-electronic properties.

International Classification:

A23F 5/04

US Classification:

426469, 426427, 426523, 34468, 34479, 34480

Abstract:

Coffee beans are roasted with heated air in a roasting chamber, and contaminant-laden exhaust air including caffeine entrained therein is discharged from the chamber. While roasting is in progress, the exhaust air from the chamber is heated, directed through a catalytic converter and cooled to a temperature between about 250 F. to 325 F. Thereafter the cooled exhaust air flows through a cooler or condenser where the temperature of the cooled exhaust air is further lowered to between about 100 F. and 155 F. , and it is then directed through a HEPA filter to remove caffeine particles that are present in the cooled air. Substantially caffeine-free clean exhaust air can then be discharged from the HEPA filter directly to the surroundings of the roasting machine such as a closed room, e. g. a retail establishment, frequented by persons.

H01L 21/283

US Classification:

438 95, 438679, 257E21159, 257E23155

Abstract:

Method of applying a conformal coating to a highly structured substrate and devices made by the disclosed methods are disclosed. An example method includes the deposition of a substantially contiguous layer of a material upon a highly structured surface within a deposition process chamber. The highly structured surface may be associated with a substrate or another layer deposited on a substrate. The method includes depositing a material having an amorphous structure on the highly structured surface at a deposition pressure of equal to or less than about 3 mTorr. The method may also include removing a portion of the amorphous material deposited on selected surfaces and depositing additional amorphous material on the highly structured surface.

Inventors:

John W. Perkins - Hialeah FL

Assignee:

Monarch Aviation, Inc. - Miami FL

International Classification:

E05F 1500

US Classification:

49280

Abstract:

Electrically-operated hydraulic and mechanical apparatus is disclosed for opening and closing a large door, for example, on a cargo airplane. Door latching or locking apparatus is also disclosed, which serves to prevent the door from being inadvertently opened at any time. The hydraulic and mechanical apparatus are sequentially activated so that, for example, before the door latching operation can begin, full closing of the door is required. Conversely, before opening of the door can occur, full unlatching of the latching mechanism must first occur.

International Classification:

H04L 29/06
G06F 3/14

Abstract:

Systems, methods, and computer systems are disclosed for establishing a screen share session. One such method comprises a collaboration server receiving a message from an application executing on a mobile communication device. The message identifies that a voice call remote to the collaboration server has been initiated by the mobile communication device and established between a calling party using the mobile communication device and one or more called parties. The collaboration server determines that the calling party and the one or more called parties in the remote voice call have an active collaboration presence with the collaboration server. The collaboration server initiates a display of a screen share user interface control on a first computing device associated with the calling party and one or more second computing devices associated with the one or more called parties. The screen share user interface control is configured to enable the calling party and the one or more called parties to establish a screen share session.
