Abstract: A set of context profiles containing profile content rules for filtering which content within a set of personal productivity applications (such as e-mail, chat, calendar, and contacts applications) is accessible by a user. Content rules support filtering content by, for example, content originator, and/or subject matter. The context profiles are centrally maintained for control of integrated, non-integrated, and/or independently administered personal productivity applications.

Abstract: A system for collecting gas samples emitted from skin and detecting concentrations of specified components therein. The system includes a collection chamber housing defining an interior space, the collection chamber housing having a gas inlet, a gas outlet, and an opening. The opening is configured for enclosing a skin portion from which to receive an emitted gas sample and sealing the interior space against the skin portion. An inert gas source is connected to the gas inlet, which is capable of allowing inert gas from the inert gas source to flow into the interior space. A gas cell is connected to the gas outlet, which is capable of allowing the inert gas and the gas sample to flow from the interior space into the gas cell. As a laser travels through the gas cell, power and optoacoustic signals are measured and used to determine a concentration of the specified component.

Abstract: Copolymers containing at least one perfluoropolyether segment and multiple aminooxalylamino groups are described. Methods of making the copolymers are also described. The copolymers can be prepared by reacting an oxalylamino-containing compound and an amine compound having at least two primary amino groups, at least two secondary amino groups, or at least one primary amino group plus at least one secondary amino group.

Abstract: A method for performing a real time testing of a mobility device located at a remote location using a test framework communicatively coupled with the mobility device by means of either a TCP/IP protocol or a UDP protocol, and configured to execute a client application is provided. A server application receives a remote command is received from the client application, for retrieving a test information. The test information is generated by communicating with an operating system of the mobility device, in response to the remote command. The test information includes information related to the operating system, the server application, and screenshot of a region of interest area on a display unit of the mobility device. The test information is compressed using a custom compressor, and is sent to the client application. Further, tests are performed by a test system based on the received test information from the test framework.
