Publication number: 20140282636Abstract: This invention relates to the prefetching of content items, for example, prefetching of videos, to make the content items accessible from a local data store (118) of the mobile device (112). A processor (114) determines for each of the multiple content items a benefit value associated with an access time. The processor (114) also determines for each of the multiple content items an estimated prefetching cost associated with a prefetching time. Then, the processor (114) selects one of the multiple content items for downloading at the associated prefetching time based on the benefit values and the prefetching cost at the prefetching time. This way, the prefetching can be managed such that the most useful content item which the user will likely access soon are downloaded while at the same time minimising the cost.Type: ApplicationFiled: October 24, 2012Publication date: September 18, 2014Applicant: NATIONAL ICT AUSTRALIA LIMITEDInventors: Lars Henrik Petander, Maximilian Ott, Robert Hitching, Yorick Georges Maziere, James Petterson, Christfried Webers, Tiberio Silva Caetano, Joop Johannes Wilhelmus Van de Van, Joseph Christian Gruba Noel

Patent number: 8744666Abstract: The present invention relates to systems and methods for vehicles to safely closely follow one another through partial automation. Following closely behind another vehicle has significant fuel savings benefits, but is unsafe when done manually by the driver. On the opposite end of the spectrum, fully autonomous solutions require inordinate amounts of technology, and a level of robustness that is currently not cost effective.Type: GrantFiled: July 5, 2012Date of Patent: June 3, 2014Assignee: Peloton Technology, Inc.Inventors: Joshua P. Switkes, Joseph Christian Gerdes, Eugene Berdichevsky

Patent number: 8537023Abstract: An automatic fault detector momentarily interrupts a provision of operating power to a load having a minimal forward-bias voltage requirement to thereby provide a testing window and then applies a test voltage during this window that is less than the minimal forward-bias voltage requirement to the load and monitors for a power-to-ground fault. By one approach the aforementioned momentarily interruption of power is neither frequent enough nor long enough in duration to substantially impair the provision of power to the load. Accordingly, load performance is not noticeably diminished. One can then responsively prohibit subsequent provision of the operating power to the load. One can then continue to monitor for the power-to-ground fault while continuing to prohibit provision of operating power to the load. If and when the fault disappears, these teachings will then accommodate automatically resuming an ordinary provision of power to the load.Type: GrantFiled: May 26, 2011Date of Patent: September 17, 2013Assignee: iLight Technologies, Inc.Inventors: Joseph Christian Ernest, Sean Edward Callahan, Edward Wayted Chen, Thomas Martin Kopera, Timothy Edward Canzano

Patent number: 7015546Abstract: Deterministically doped field-effect devices and methods of making same. One or more dopant atoms, also referred to as impurities or impurity atoms, are arranged in the channel region of a device in engineered arrays. Component atoms of an engineered array are substantially fixed by controlled placement in order to provide a barrier topology designed to control of source-drain carrier flow to realize an ultra-small device with appropriate, consistent performance characteristics. Devices can be made by placing atoms using proximity probe manipulation, ion implantation, by facilitating self-assembly of the atoms as necessary, or other techniques. These atomic placement techniques are combined in example embodiments with traditional methods of forming a substrate, insulators, gates, and any other structural elements needed in order to produce practical field-effect devices.Type: GrantFiled: August 14, 2003Date of Patent: March 21, 2006Assignee: Semiconductor Research CorporationInventors: Daniel Joseph Christian Herr, Victor Vladimirovich Zhirnov
