Abstract:
A switching device provided on a package substrate for altering the built-in function of an IC chip includes a first contact, a second contact, and a conductive layer. The first contact is electrically connected to a signal-receiving end of the package substrate, and the second contact is electrically connected to a voltage source of the package substrate. The conductive layer is used for electrically connecting the first contact with the second contact.
Abstract:
A system customizes a news document associated with a user of a news aggregation service. The system includes a remote news aggregation server configured to create a news aggregation service document based on a request received from the user. The remote news aggregation server identifies news content from a plurality of news source servers based on the received request and presents the identified news, content in the news aggregation service document. The remote news aggregation server is further configured to receive a request from the user to remove a news item from the presented news content and removing the requested news item from the identified news content. Updated news content is presented in an updated news aggregation service document.
Abstract:
An assembled structure of a large-sized LED lamp includes a substrate. One surface of the substrate is provided with a plurality of LED modules. Each LED module comprises a circuit board and a plurality of LEDs fixedly connected to the circuit board. A lamp mask is locked onto the substrate to cover and protect the LED modules. A sealing material is provided between the lamp mask and the substrate to protect the permeation of liquid. Further, at the positions of the other surface of the substrate, heat-dissipating modules are provided to correspond to each LED module, respectively. The heat-dissipating modules are used to dissipate heat generated from the LEDs. A lamp cover is covered to the exterior of the heat-dissipating modules. The lamp cover is locked onto the substrate. With the modulization of each constituent element, the detachment, assembly and repair of the present invention can be much simpler and more convenient.
Abstract:
An auto-switching converter with PWM and PFM selection supplies a boosted DC power to a load through a power switch unit. A starter outputs a starting-enabling signal. An auto PWM/PFM controller is connected to the starter for outputting a selection signal. A controller and a PFM controller are connected to the auto PWM/PFM controller, the power switch unit and the load for transmitting a PWM control signal and a PFM control signal to the power switch unit, respectively, for controlling the switching action of the power switch unit.
Abstract:
A protective cover for protecting heat-conductive material of a heat sink includes a first plate with an opening to enclose the heat-conductive material and a second plate foldable to the first plate. Such that the heat-conductive material can be precisely protected by the protective cover to be isolated from contamination but with good air-circulation.

Abstract:
An air-guiding structure for a heat-dissipating fin is manufactured by providing plural sets of air-guiding portions on each heat-dissipating fin. Each air-guiding-portion includes a plurality of thorns made by stamping. The thorns are arranged non-linearly and oriented to face the inlet or the outlet for external cooling air. With the above arrangement, when the external cooling air enters the inlet of the heat-dissipating fin and passes through the flowing path, as soon as contacting with the thorns of the air-guiding portion, the cooling air is hindered to form a three-dimensional turbulent flow on the heat-dissipating fin. As a result, the duration within which the cooling air stays in the heat-dissipating fin can be extended to efficiently carry the heat source out of the heat-dissipating fins, thereby to improve the efficiency in heat dissipation.
Abstract:
A method for manufacturing a heat pipe having an enlarged portion includes the steps of: preparing a hollow tubular material having a uniform outer diameter; forming the tubular material with an enlarged portion having a different or larger outer diameter by narrowing or enlarging the tubular material; arranging a capillary structure into the tubular material; filling a working fluid into the tubular material after sealing one end of the tubular material; sealing the end to form a heat pipe after performing a degassing operation; and pressing the enlarged portion obtained in the previous step to form a flattened enlarged portion on the heat pipe.
Abstract:
The present invention is directed to a LED lamp and the heat-dissipating structure thereof. The heat-dissipating structure is used to dissipate the heat generated by the LED and comprises a first heat-dissipating body and a second heat-dissipating body. The first heat-dissipating body has a casing with an opening formed thereon. The second heat-dissipating body is connected on the first heat-dissipating body and comprises at least one heat pipe and a plurality of heat-dissipating fins connected to the heat pipe. With this arrangement, the LED continuously operates under a suitable working temperature and the life of the LED can thus be prolonged.
