A second electronic device generates second signature information according to the second signature request. The signature server generates a first credential request and a second credential request according to the first signature information and the second signature information. The credential server transmits a first credential object and a second credential object to the signature server in response to the first credential request and the second credential request.

Abstract: A connector includes a contact interface. The contact interface includes a surface, multiple metal contacts and at least two bumps. The bumps are formed on the surface. The bumps are of a height not greater than a height by which the multiple metal contacts protrude from the surface, and thus the bumps function as a restraint or a buffer to the contact interface and thus prevent the multiple metal contacts from undergoing excessive deformation when the contact interface is connected to another contact interface.

The signal test board controllably causes the burn-in board to provide power to at least one of the plurality of test sockets according to the signal to perform a test process. The at least one socket power module has a power compensation mechanism for ensuring that the devices under test receive the power equally.

Abstract: A closed-loop liquid-cooled burn-in device includes a water tank and at least one test socket. The water tank is in fluid connection with the at least one test socket by a loop. The water tank has a first reservoir and a second reservoir. The first reservoir stores a low-temperature cooling liquid, and the second reservoir stores a high-temperature cooling liquid. The first reservoir provides a heating unit for heating up the low-temperature cooling liquid to control the temperature of the cooling liquid supplied to the at least one test socket.

Abstract: A function card fixing structure is provided, comprising a main body including a first portion and a second portion, wherein the first portion is perpendicular to the second portion, and the first portion comprises a plurality of trenches extending along a direction of a long axis of the main body. A sliding component is disposed at a side of the second portion, wherein the sliding component comprises a plate body and a locking portion, and one side of the plate body comprises a plurality of openings and stopping portions. A releasing component comprising a locking portion is at one side, wherein the locking portion of the releasing component is locked with the locking portion of the sliding component.

Abstract: A chain including chain-link units pivotally connected with each other. Each chain-link unit includes two lateral plates, a first link plate and a second link plate. Two ends of the lateral plates are defined as a first end and a second end. Two first pin-joint parts are configured near the first ends of the lateral plates respectively, and two second pin-joint parts are configured near the second ends of the lateral plates respectively. The chain-link units are pivotally connected with each other via the first pin-joint part and the second pin-joint part. Thus, the chain-link units are common, and each can be the starting chain-link unit, the middle chain-link unit or the ending chain-link unit. They can be easily assembled without screws, which further reduce the time consumption. Moreover, the noise made as the chain works can be reduced, and a buffering function can also be provided.

Abstract: Scheduling methods for a multi-core processor system including multiple processors are provided. First, a process to be executed is chosen from a ready queue and analyzed to obtain a power consumption value of the process to be executed. Next, an idle processor is chosen from the processors and a total power consumption value of system through which the process to be executed is being executed in the idle processor is estimated to obtain a first prediction result based on the obtained power consumption value. It is then determined whether to execute the process to be executed in the idle processor according to the first predicted value and a predetermined upper limit value. In some embodiments, the scheduling method may further provide preemption scheduling such that the process with high priority can be preferentially executed and process can flexible switch among different processor core clusters.

Abstract: For testing a high density BGA package, a central pressure block is designed to press against the chip of the package during test in a test socket. High density socket probe causes high pressure against the package, especially the area under the chip. With the central pressure block of the present invention, the high density BGA package is prevented from deformation because the central pressure block pressing downward against the chip, which balances the pressure coming upward from the high density socket probes under the circuit board in the area under the chip.
