摘要:
The present invention provides a method for restoring a computer operation system comprising at least steps of: a) backing up information related to start up of the computer in an HPA of a hard disk; b) providing a self-checking module in the HPA of the hard disk, and additionally configuring a command for invoking the self-checking module in BIOS of the computer; c) invoking the self-checking module by the BIOS when the computer is booted from the hard disk, and determining by the self-checking module, whether the information related to start up of the computer is destroyed or not, if so, restoring the destroyed parts and then starting up the computer, and if not, directly starting up the computer. With the present invention, each time the computer is booted from the hard disk, the system will automatically check OS boot program files, hard disk boot information, partition table information and data information in a boot sector of a boot partition, and restore those destroyed parts without users' intervention, and thus it facilitates users' utilizations. Meanwhile, the backed up data are stored with the HPA, and the security of the backed up data is ensured.

摘要:
A portable electronic device includes a main body, a flip cover, and a hinge assembly. The flip cover is rotatably fixed on the main body via the hinge assembly. The hinge assembly includes a sensing module, a hinge mechanism, and a microcontroller. The sensing module is configured to detect control signals. The hinge mechanism is configured to control an angle between the flip cover and the main body. The microcontroller is electrically connected to the sensing module. The microcontroller receives the control signals from the sensing module, and controls the hinge mechanism to rotate to a specified angle according to the control signals. The angle between the flip cover and the main body is automatically adjusted correspondingly.

Systems and methods of reducing service jitter in WFQ scheduling schemes used in packet traffic management are described. Service jitter is the variance in time between when a queue should have been selected for servicing and when it was actually serviced. The service jitter is generally not a problem in lower speed applications but in a high speed implementation such as a OC192 device latency can lead to downstream service contract violations. According to the invention jitter is controlled by applying a dampening factor to a difference amount that is used by the WFQ process to adjust its timing of queue selection. The difference amount is queue-specific and is a running difference between calculated and actual queue servicing times.

Aromatic and aliphatic organic thiol compounds are disclosed which can be utilized to plasticize and/or stabilize halogen-containing polymer compositions, especially poly(vinyl chloride) compositions. Compounds of the present invention are utilized in polymers normally susceptible to deterioration and color change, which typically occurs during processing of the polymer or exposure to certain environments.
摘要:
A support stand includes a first support assembly, a second support assembly, a first connecting assembly connecting one end of the first support assembly and the second support assembly. A second connecting assembly connects the other ends of the first support assembly and the second support assembly. The first support assembly includes two first support mechanisms, each first support mechanism includes a main body, and a first support rod hinged on the main body in a first direction. When the first support rods rotate around the first direction to a back side of the support stand, the first connecting assembly and the second connecting assembly are tilted by the first support rods and the second support assembly.
摘要:
At telecommunications switches and routers, RED (random early packet discard) uses the queue depth to determine whether to keep or discard each packet as it arrives at a queue. This is done by determining a discard probability (P), which is dependent on the average depth of the queue, and comparing the discard probability to a random number. One way of performing the invention uses the summed discard probabilities, instead of counting the number of packets (count) and multiplying that by the current discard probability, as in the prior art. The resulting sum is compared to the random number for discard operation. The disclosure further describes a more accurate way of calculating average depth of a queue, especially when the queue encounters periods of idleness.
