2067results about How to "Reduce startup time" patented technology

A mechanism is provided in a debugger for building a file information database while significantly reducing debug startup time. For each line number table, the mechanism of the present invention reads the header section and determines all the source files that contribute to the line number table. The mechanism also makes note of the line number table offset. The mechanism then inserts the source filename into the file information database. In one preferred embodiment, the file information database is implemented as a hash table. Searching time occurs during an interactive debug session; therefore, the searching time is not easily detectable to a user, thus creating the perception of a faster interactive debugging session.

In fuel supply systems with two fuel pumps connected in series and fuel valves that inject directly into the combustion chamber, there have been occasional problems. The proposal is made that in order to eliminate these problems, the first fuel pump operates with increased delivery capacity, particularly during the startup process and in the event of high fuel temperature. The fuel supply system is provided for an internal combustion engine of a vehicle.

This invention is directed to an apparatus and method for providing improved control of fuel, preferably gaseous fuel, to an internal combustion engine such that each cylinder of the engine will operate within a predetermined tolerance off of its lean misfire limit. The disclosed system introduces fuel to the engine at two locations: (1) upstream of the intake manifold to provide premixing of a majority of the fuel with air, and (2) near the intake valve of each cylinder for tailoring the fuel flow to each cylinder to achieve that fuel-to-air ratio which is necessary to maintain each cylinder at the desired tolerance from the lean misfire limit. Several calibration and control methods are described to maximize performance of the fuel system, including the use of a misfire detection technique to determine the lean misfire limit of each cylinder to allow the respective port fuel injector to provide a specified margin from lean misfire. The present invention enhances engine performance and driveability while reducing exhaust emissions.

The invention discloses a unified extensible firmware interface (UEFI) trusted supporting system and a method for controlling the same. The UEFI trusted supporting system comprises UEFI trusted supporting system firmware and a trusted platform control module (TPCM), wherein the UEFI trusted supporting system firmware is stored on a nonvolatile memory and connected with the TPCM by a system bus; and the TPCM is connected with a trusted computation platform by the system bus. The method for controlling the UEFI trusted supporting system comprises the following steps of: firstly, loading a driver for the TPCM; secondly, sequentially authenticating the identity of users, performing measurement validation on a basis input/output system (BIOS), the characteristic data of hardware and a master boot record (MBR) / operating system (OS) Loader/OS Kernel, controlling different hardware peripheral interfaces according to an I/O strategy of the users, and performing safety guide setting on the system by a safety guide module; and finally, controlling by the BIOS or the OS. By the system and the method, trusted computation, the configuration management of the TPCM, the backup/recovery of the BIOS/MBR/OS Loader/OS Kernel and the physical protection of key data are realized on a firmware layer. The invention can be simultaneously applied to a Linux system which opens source codes and a Windows system which does not open the source codes, so that a fault does not occur in a trust chain between BIOS firmware and OS software, and the safety of a computer and the friendliness of human-computer interaction are improved.

A low-voltage operating block and a high-voltage operating block are controlled at the same soft start voltage as that employed at the time of start-up. At a point in time at which an output DC voltage has reached an expected value, a control signal of the low-voltage operating block is switched to a control signal of the high-voltage operating block. As a result, switching is smoothly performed without involvement of occurrence of a variation in the output voltage before and after switching operation. In a switching power supply unit having a low-voltage operating block and a high-voltage operating block, which are intended for producing a higher DC voltage from a low power supply voltage, it prevents occurrence of a rush current and a start-up failure, which would otherwise be caused by switching operation.

An applet is used to deliver a persistent caching mechanism. An initial package of the applet incorporates a lightweight caching mechanism into its root set of classes. The remainder of the applet are divided into functional modules that can be subsequently downloaded as needed. The initial applet and caching mechanism is packaged and signed in a package using tools and procedures native to each platform; and each functional module is packaged and signed in a generic, platform-independent fashion for verification and loading by any of the various platform-dependent initial applet packages. In this way, the same functional module portions of the applet (which may comprise the bulk of the applet) are cached and loaded in a platform-independent manner without requiring or relying on any caching mechanism built into a platform such as a web browser or other applet execution environment.

A fuel cell power plant comprises a fuel cell stack (1) constituted by a plurality of fuel cells which perform electric power generation by means of a reaction of hydrogen and oxygen. A controller (16) determines whether or not moisture inside the fuel cell stack (1) is frozen, and if the moisture is frozen, the controller (16) causes the fuel cell stack (1) to perform intermittent electric power generation via an inverter (27) while continuing to supply oxygen to the fuel cell stack (1). The fuel cell stack (1) generates heat as a result of the electric power generation, whereby moisture is generated in a cathode (9). During the periods in which electric power generation is not performed, the oxygen which is supplied to the cathode (9) of the fuel cells scavenges the generated moisture, thereby ensuring the supply of oxygen to the cathode (9) during electric power generation.

Information is more efficiently distributed between master and slave information handling systems interfaced through a blocking network of switches by storing the information on switches within the blocking network and distributing the information from the switches. As an example, an application distribution module located on a leaf switch distributes an application, such as an operating system, to connected slave nodes so that the slave nodes do not have to retrieve the operating system from the master node through the blocking network. For instance, a PXE boot request from a slave node to the master node is intercepted at the leaf switch to allow the slave node to boot from an image of the operating system stored in local memory of the leaf switch.

An exemplary fast start-up crystal oscillator with reduced start-up time. The exemplary oscillator reduces the start-up time (i.e., the time taken to attain sustained stable oscillations after the power is turned on) by increasing the negative resistance of a circuit. Increasing the negative resistance increases the rate of growth of the oscillations, thereby reducing start-up time. The exemplary crystal oscillator includes a gain stage with negative resistance. A crystal with shunt capacitance is placed in the feedback loop of the gain stage. A buffer is coupled to the gain stage such that it blocks the crystal shunt capacitance from loading the gain stage, effectively increasing the negative resistance of the gain stage. Further, an oscillation detection and control circuit is coupled between the crystal and the gain stage. The oscillation detection and control circuit connects the buffer during start-up, and disconnects the buffer once an oscillation signal attains sustained stable oscillations.
