Abstract: A silver compound having a silver complex structure composed of silver ion, 2,2,6,6-tetramethyl-3,5-heptanedionato, and diethylenetriamine is disclosed. A silver ink is prepared by the silver compound applied for inkjet printing of a flexible substrate. A method for inkjet printing of the flexible substrate comprises the steps of pre-heating the flexible substrate to the temperature of 60° C., inkjet printing the flexible substrate with the silver ink thereon, and heating the flexible substrate under a low temperature to form a thin film of silver conductive pattern thereon. The silver conductive pattern has excellent electrical conductivity and a resistance value proximate to that of a general silver slug.

Abstract: In some implementations, power provided to a computing system, such as a rack system, may be interrupted. This interruption is detected, and in response, power from a battery backup system is directed to the computing system to replace the interrupted power source, which in some implementations may be a main AC power grid source. A signal is received indicating that a backup power source, for example a backup generator system, is online and prepared to deliver power to the computing system. For an initial period of time, this backup power source is prevented from providing power to the computing system. For example, the backup generator system may be providing power to a power supply unit of the computing system, but the power is not allowed to flow to the computing system.

Abstract: The automatic umbrella has an improved tube unit which contains a first tube, a second tube, and a third tube telescoping together. An inner plug is positioned inside the second tube. A reinforcing tube is housed in the second tube and capable of moving upward through the inner plug. The main spring has its top end against the reinforcing tube, and its bottom end in a lower part of the first tube. The secondary spring is inside the third tube with a top end against the inner plug of the top nest and a bottom end against the inner plug of the second tube. The tube unit enjoys enhanced resilience when the automatic umbrella is opened. When the umbrella is closed, two sets of springs are compressed at separate instants and their resilience cancels each other indirectly. The strength to close the umbrella is therefore reduced.

Abstract: A method for forming a conductive film at room temperature is provided and includes steps of: adding AgNO3 into a first solution of dodecanoic acid; dropping n-butylamine and a diluted aqueous solution of a reducing agent into the first solution in turn, so as to initially obtain the dodecanoate-protected silver nanoparticles as a capping ligand; then using cyclohexane as a solvent to apply the silver nanoparticles onto a surface of a substrate to form a patterned film of silver nanoparticles; and finally immersing the substrate into a high concentrated aqueous solution of a reducing agent to chemically reduce the patterned film of silver nanoparticles into a conductive silver film. Thus, a patterned film or circuit can be conveniently and rapidly formed, and the silver nanoparticles can be applied to flexible substrates with low material cost and temperature sensitivity.

Abstract: A method and apparatus for maximizing the usage of a testhead of an in-circuit tester is presented. A testhead execution supervisor interfaces between a testhead controller and a graphical user interface used to enter manual tests. The testhead execution supervisor adds tests to be submitted to the testhead to one or more queues according to a priority scheme. Tests may be submitted to the testhead execution supervisor both as manual tests entered via the graphical user interface and as automatically generated tests generated by an automatic debug module. The automatic debug module may automatically generate tests for execution by the testhead that are executed when the testhead is idle, for example when no higher priority manual tests are scheduled.

Abstract: A method for configuring an automated in-circuit test debugger is presented. The novel test debug and optimization configuration technique configures expert knowledge into a knowledge framework for use by an automated test debug and optimization system for automating the formulation of a valid stable in-circuit test for execution on an integrated circuit tester. In a system that includes a rule-based controller for controlling interaction between the test-head controller of an integrated circuit tester and an automated debug system, the invention includes a knowledge framework and a rule-based editor. The knowledge framework stores test knowledge in the representation of rules that represent a debugging strategy. The rule-based editor facilitates the use of rules as knowledge to debug or optimize an in-circuit test that is to be executed on the integrated circuit tester.

Abstract: A light emitting base. The light emitting base carries a solid material and comprises a base structure, at least one light emitting device, a control module and a power supply. The base structure is used for carrying a solid material and provided with at least one light emitting device. The control module is used to control patterns, amplitude and duration of the light emission pulses. The power supply provides electric power to the light emitting devices and the control module.

Abstract: A distributed control switching system where calls, to and from a directory number that is shared by a key-system group of terminals, are processed cooperatiavely by multiple, distributed control units but in response to busy/idle data for the shared directory number stored advantageously by only a lead one of the control units. In addition to processing a call, for example to complete a connection to or from one of the terminals of the group, the multiple control units also cooperate as the call progresses to inform each of the group terminals of the call status as though the terminals were connected in parallel to a central office line as in an electromechanical key system.
