Abstract: Communications over short-range connections are used to facilitate whether access to resources is to be granted. For example, upon device discovery of one of an electronic user device and an electronic client device by the other device over a Bluetooth Low Energy connection, an access-enabling code associated with a user device or account can be evaluated for validity and applicability with respect to one or more particular resource specifications. User identity can be verified by comparing the user against previously obtained biometric information.

Abstract: In a system for providing media content to a communication device, a device capabilities determination is made by a rules engine that compares content attributes with constraints on those attributes for a device. Metadata describing the content is derived and entered into a database. As the specifications of different devices are entered into the system, corresponding constraints are associated with the devices that tell the engine the valid range of values for the content attributes. The engine creates an available content library for each class of devices by excluding all instances of content that have attributes outside the range of values prescribed in the constraints. A similar rule set determines whether the content can be distributed through a particular delivery channel, based on the distribution channel capacity to support a media type.

Abstract: A hydraulic door opener provides a simplified mechanism for two-speed operation and for controlling the release of a brake that normally holds the door against movement. The mechanism includes a bypass valve between a fluid reservoir feeding the pump and the close control line running between the pump and the hydraulic motor. Fluid flow is directed from the close control line so that the door can be closed at slower rate than it is opened using a single speed motor. A brake control valve releases the brake when the control lines are pressurized.
