  • Publication number: 20120005511
    Abstract: An apparatus and method for a power-efficient framework to maintain data synchronization of a mobile personal computer (MPC) are described. In one embodiment, the method includes the detection of a data synchronization wakeup event while the MPC is operating according to a sleep state. Subsequent to wakeup event, at least one system resource is disabled to provide a minimum number of system resources required to re-establish a network connection. In one embodiment, user data from a network server is synchronized on the MPC without user intervention; the mobile platform system resumes operation according to the sleep state. In one embodiment, a wakeup alarm is programmed according to a user history profile regarding received e-mails. In a further embodiment, data synchronizing involves disabling a display, and throttling the system processor to operate at a reduced frequency. Other embodiments are described and claimed.

  • Publication number: 20110315118
    Abstract: Various fuel injection systems and fuel injectors are disclosed that provide varying cooling rates for fuel injectors connected in series to fuel supply and drain rail. The local cooling rate for each injector is manipulated to balance the heat flux or heat transfer across the injectors disposed along the rail. The cooling rates may be manipulated by varying sizes of openings or slots in the nozzle case, by varying annular spaces disposed between the nozzle case and the portion of the injector body that houses the actuator and solenoid assembly, and by varying the size of annular spaces disposed between the nozzle case and the cylinder head. Strategic placement of slots in the nozzle case that direct more flow at the portion of the injector body that houses the actuator and solenoid assembly may also be employed. As a result, the operating temperatures of fuel injectors connected in series to a fuel rail can be manipulated and moderated so the downstream injectors are not prone to overheating.

  • Patent number: 7658631
    Abstract: A fuel injector includes first and second electrical actuators positioned within an injector body. First and second pairs of electrical conductors extend from a socket connector outside of the injector body to the first and second electrical actuators, respectively. The electrical conductors extend through an elastomeric sealing member that seals against fuel leakage from the fuel injector. The elastomeric sealing member provides annular sealing ridges in sealing contact with an access passage of the injector body and includes individual conductor seal passages that form seals around the outer surface of the individual electrical conductors. The elastomeric sealing member includes features that facilitate assembly of the fuel injector in a manner that reduces risk of damage to the sealing strategy.

  • Patent number: 5561780
    Abstract: The write-combining buffer combines data from separate data write operations into cache-line-sized buffer units for uncacheable types of data, such as frame buffer data. The write-combining buffer is implemented within a microprocessor having a data cache unit storing cacheable data within cache-lines. The data cache unit includes components and circuitry provided for efficiently inputting and outputting cache-line-sized units of data. By combining many uncacheable data write operations within a single cache-line-sized buffer, the circuitry and techniques employed for processing cache-lines are exploited in the processing of uncacheable data as well. A particular implementation is described wherein uncacheable data units corresponding to graphics write operations within an out-of-order microprocessor are combined into cache-line-sized buffers, then transmitted to a frame buffer using a burst mode eviction.
