US08732202B2 Access requests with cache intentions
A lease system is described herein that allows clients to request a lease to a remote file, wherein the lease permits access to the file across multiple applications using multiple handles without extra round trips to a server. When multiple applications on the same client (or multiple components of the same application) request access to the same file, the client specifies the same lease identifier to the server for each open request or may handle the request from the cache based on the existing lease. Because the server identifies the client's cache at the client level rather than the individual file request level, the client receives fewer break notifications and is able to cache remote files in more circumstances. Thus, by providing the ability to cache data in more circumstances common with modern applications, the lease system reduces bandwidth, improves server scalability, and provides faster access to data.
US08732200B2 System and method for controlling access to a database object

US08732184B2 Method and apparatus for remotely displaying a list by determining a quantity of data to send based on the list size and the display control size
A system and method for remotely displaying a plurality of data items is disclosed. The system determines a total quantity of displayable data items and optionally receives an indication of a display control size from a remote client. The server stores a threshold value indicating a relationship between a quantity of data items and a size of a display control. The server compares the quantity of data items and the received indication of the display control size. If the comparison exceeds the threshold value, the server sends a subset of the items to the remote client for display, and sends additional items as requested by the remote client. If the comparison is less than the threshold value, the server sends each of the items to the remote client for display. The server repeats this comparison for changes in the quantity of data items or the size of the display control.

When an internal combustion engine is cranked up from a stopped position of a piston in a restart-time first ignition cylinder which is scheduled to start a combustion at the time of an automatic restart of the engine under an automatic stop of the engine during an idling-stop control, a restart-time ignition time interval between a time point when the cranking of the engine is started and a time point when the restart-time first ignition cylinder is initially ignited is calculated.

For each video frame, the histogram of the pixel luminance values is calculated. The calculated histogram is divided into three regions that are equalized independently of the other. The equalized values are averaged with the original pixel values with a weighting factor that depends on the shape of the histogram. The weighting factors can be also chosen differently for the three regions to enhance the darker regions more than the brighter ones. The statistics calculated from one frame are used to enhance the next frame such that frame buffers are not required. Many of the calculations are done in the inactive time between two frames.
