Abstract: A keyboard includes a first housing having a plurality of first magnetic elements, a keystroke module having a key portion disposed on the first housing, a second housing combining with the first housing and has an opening, and an actuating assembly. The keystroke module is disposed corresponding to the opening. The actuating assembly is disposed movably on the second housing and has a plurality of second magnetic elements. The keystroke module is not protruded from the opening and is at a packing position. When the actuating assembly is moved along an actuating direction, at least one first magnetic element and at least one second magnetic element attract to each other to shorten the distance, which brings the second housing to move relatively to the first housing so that the key portion of the keystroke module passes though the opening and is at a using position.

Abstract: The present invention discloses a real-time responsive motor control system comprising a central MCU (Microcontroller Unit) core logic and at least one PWM (Pulse Width Modulation) MCU core logic. The central MCU core logic takes care of all interrupt events. The PWM (Pulse Width Modulation) MCU core logic is dedicated to the transformation of PWM signals so that the PWM signals output to a motor device are highly accurate. Further, the central MCU core logic may directly control the PWM MCU core logics so that the switching timing of the PWM signals is even more accurate. The present invention provides a modularized hardware architecture with flexible software control. The system design is simple and the associated cost is reduced.

Abstract: In a multiple microcontroller system comprising multiple MCU core logics, a multiple-MCU-core-logic selection operand is provided in an instruction according to this invention. The multiple-MCU-core-logic selection operand specifies or selects a corresponding MCU core logic in the system, and also specifies or selects a sub-unit of the MCU core logic, when necessary. Any MCU core logic in the system may be used as a main operation microcontroller unit to fetch and decode this instruction. An operation action corresponding to an operation code in the instruction is performed on the selected MCU core logic corresponding to the multiple-MCU-core-logic selection operand. The multiple microcontroller system can therefore directly specify an MCU core logic, and its sub-unit if necessary, on which a desired action is to be performed. Moreover, different MCUs in the multiple microcontroller system can share resources and control one another. True parallel processing is thus achieved.

Abstract: The present invention relates to an air scoop cooler. The air scoop cooler comprises a hollow duct, an exhaust opening, which can install an exhaust fan, and an entry opening on the top of the duct. The duct comprises a pull, a pin, and a hook to attach and to couple easily with a chassis of computer. On the top of the duct also comprises a plurality of protrusions against the chassis to fix. The CPU including its radiator and part of the mainboard including its electronic devices can be covered in the duct. The duct isolate noise of the fan of the radiator of CPU, and the exhaust fan exhausts inside warm air so that the outside cool air will stream into the duct via the entry opening forming airflow convection. In this invention the convection in the air scoop cooler can efficiently dissipate heat from working CPU and other electronic devices covered in the duct outside the chassis to cool devices down, and also keep silent operation.

Abstract: The invention provides compositions and methods for providing edible gloss coatings for foods on which a gloss coating is desirable. The invention is particularly useful for providing gloss coatings to confections, such as chocolates, hard panned confections, soft panned confections, yogurt coated confections, starch molded confections, and compressed sugar tablets. The invention further provides methods for delaying the development of rancidity in nuts by coating the nut with a film-forming coating in a solution containing a surfactant in an amount larger than that which reduces the surface energy of the solution to its lowest level.
