Abstract:

A method of providing hydraulic pressure for mechanical work from an engine lubricating system in an internal combustion engine by supplying oil to an engine lubrication gallery for lubricating the engine and at least one variable oil demand accessory. Each of the variable oil demand accessories have individual pressure regulators. The output of the variable displacement pump is regulated to the sum of fluid flow required by the engine lubricating system and the demand for fluid generated by the individual pressure regulators on each of the engine accessories, regardless of the engine output.

Abstract:

A cache server includes a media serving engine that is capable of distributing media content. A cache engine is coupled to the media serving engine and capable of caching media content. A set of cache policies is accessible by the cache engine to define the operation of the cache engine. The cache server can be configured to operate as either a cache server or an origin server. The cache server also includes a data communication interface coupled to the cache engine and the media serving engine to allow the cache engine to receive media content across a network and to allow the media serving engine to distribute media content across the network. The cache policies include policies for distributing media content from the media server, policies for handling cache misses, and policies for prefetching media content.

Abstract:

Pairing service technologies is described. In embodiment(s), peripheral devices can be discovered, such as by a computer device, and a peripheral device can be configured with multiple services that each correspond to one or more data communication protocols. The multiple services of the peripheral device can be determined, and a pairing sequence can be prioritized for the multiple services. The data communication protocol(s) can then be paired according to the pairing sequence to configure the multiple services of the peripheral device.

Inventors:

David Roth - West Bloomfield MI, US

Assignee:

Daimler Chrysler Corporation

International Classification:

F01P007/14

US Classification:

123/041100

Abstract:

A dual temperature control system as part of an engine cooling system. In one aspect, a valve is regulated as a function of engine load and disposed in a by-pass line between the radiator and the coolant pump. The valve is designed to normally block the by-pass line, but permits coolant to by-pass the thermostat and be conveyed from the radiator to the engine when the load of the engine approaches a wide-open-throttle condition. In another aspect, both high-temperature and low-temperature thermostats are employed and a normally closed valve is actuated when the load of the engine approaches a wide-open-throttle condition to permit coolant to be conveyed through the low-temperature thermostat and on to the engine.

US Classification:

711118000

Abstract:

Improved caching control for streaming media includes one or more cache control directives associated with streaming media content that can be used by a source of the streaming media content to identify how caching proxy servers are to handle the streaming media content. Upon receipt of the streaming media content, the caching proxy servers handle the content as indicated by the cache control directive(s).

Abstract:

A framework for users to connect to wireless devices, regardless of the underlying wireless technology. The framework has a modular structure, including discovery handlers, pairing handlers, and pairing ceremony modules. Discovery and pairing handlers are specific to each wireless technology, enabling discovery of wireless devices, and connection to the device. Pairing ceremony modules are technology independent, and may be invoked by any pairing handler, regardless of the wireless technology employed by a device. The framework provides an aggregation of wireless technologies into a common user interface, improving the user's experience and expanding possibilities for use of wireless technologies.
