Intelligent Power and Control Policy for Automotive Applications
U.S. Patent Application No. 20140121898
Automobiles have gone from a simple form of transportation to become a highly computerized environment. Through monitor displays, users can interact with a variety of services, including different radio formats, media, navigational tools and more. These services must communicate with Internet servers and data systems to process commands and retrieve display content, requiring a source of energy to power these systems.
Technology systems found in automobiles are often designed so that low-power states can be implemented during operation. A low-power state allows the car or truck to conserve energy when these services aren’t required by drivers or passengers. For example, if driving on an isolated highway, some auto technologies will stop monitoring traffic data typically used for routing. However, these systems still have a difficult time of determining when to enter a low-power state, or the proper time to return to normal power.
Broadcom filed this patent application with the USPTO in November 2012 to protect a new method of controlling a device coupled to an automotive area network (AAN). The application, however, claims the benefit of U.S. Provisional Application No. 61/719,581, which was filed less than two weeks earlier on October 29, 2012. The system specifically described in this application can also be used in a variety of vehicle environments, including buses, airplanes or boats. This device is capable of sending control messages to various on-board technological systems in response to various collected pieces of data.
This system relies on the use of sensors for monitoring vehicle acceleration, temperature, time of day, anticipated arrival time and other pieces of information. This data informs the AAN control device to adjust the power state of any automobile subsystems, including safety systems, entertainment systems or navigation systems. Car owners can set up profiles that focus power on various systems; for instance, a parent who drives many children can set up an “entertainment centric” profile to ensure that enough power is reserved for entertainment systems installed in a car.
As Claim 1 states, Broadcom is petitioning the USPTO for the right to protect:
“A method for use in a device communicatively coupled to an automotive area network (AAN) associated with a vehicle, the method comprising: obtaining, by a processor, input from the vehicle, the input indicating a current operating environment of the vehicle; obtaining, by the processor, a control policy indicating a balance between power usage of the device and a performance level of the device for at least the current operating environment; controlling, by the processor, a power state of at least a physical layer (PHY) portion of a communications interface of the device based on the input from the vehicle and the control policy; and dynamically rebalancing the power usage and performance level of the device over time to account for changes in the operating environment of the vehicle.”
Other Patent Applications
A wide array of intriguing computer technologies are at the core of an assortment of Broadcom patent applications which we took a close look at today. American consumers may benefit from many of these inventions in media systems and electronic devices during the coming years. Systems for aiding audio systems owners in setting up their speakers properly are described in U.S. Patent Application No. 20140119552, which is titled Loudspeaker Localization With a Microphone Array. This would protect a system that prevents audio quality degradation because of poorly placed loudspeakers through the use of a microphone array. This microphone array helps the system apply cancellation filters to remove echoes or other audio effects impacting playback. Methods for collecting and displaying information related to media content being played are discussed in U.S. Patent Application No. 20140112644, entitled Collection and Concurrent Integration of Supplemental Information Related to Currently Playing Media. This supplemental information, collected through the use of meta data, can be displayed through various media systems, including televisions, computers and electronic devices.
Electronic devices are the focus of another pair of patent applications which caught our eyes during our look at Broadcom’s recently developed technologies. U.S. Patent Application No. 20140105111, filed under the title Over the Air Programming Via a Broadband Access Gateway, would protect better methods of provisioning electronic devices with software and firmware upgrades. The over-the-air programming method is designed to overcome shortcomings associated with communicating with device networks while inside of a building, which signals cannot easily permeate. U.S. Patent Application No. 20140091755, titled Wireless Power Transfer Adaptation Triggers, describes a device for creating a wireless environment of power transfer for devices that includes an event detection module. The event detection module can analyze data, such as the presence of a human user or the time of day, to affect the mode of operation or turn off applications and communication features.
