Abstract:
An apparatus for regulating voltage and power in a computer system is disclosed. The voltage and power regulation is performed by voltage regulation circuitry on a voltage regulator module (200). The voltage regulator module (200) is a detachable unit which interfaces with the motherboard (340) through a socket connector (335). The socket connector (335) has a fixed pin definition which allows a variety of voltage regulator modules (200) programmed to regulate voltages and power at different levels to be implemented on the motherboard (340).

Abstract:
본 발명은 원적외선 방사를 이용한 방열판 미부착형 엘이디 형광등에 관한 것이다. 본 발명은 비메탈 양면 PCB 기판의 양면의 동박층을 박리시켜 회로를 형성하되, LED가 직렬로 설치되는 부분의 동박층 면적을 최대화하고, 회로부품은 PCB의 외곽에 설치되고, LED가 미설치되는 기판 표면에는 연결 회로를 형성하도록 구성되어 있다. 본 발명에 의해 적외선 방사율을 활용하여 방열판이 부착되지 않았음에도 불구하고 우수한 방열 효과를 갖게 된다.
Abstract:
A multi-layer micro-printed circuit board (PCB) is disclosed, which defines a magnetic component (500), such as a transformer, using planar technology. Instead of using the traditional twelve-layer PCB incorporating both a primary and a secondary winding, this invention stacks multiple PCBs (525, 530, 535), each having four or six layers and each including a single winding (either the primary or the secondary). The PCBs are stacked in an offset arrangement such that the pins (501-504A) penetrating the PCB or PCBs including the primary winding or windings do not penetrate the PCB or PCBs including the secondary winding or windings. Additionally, this offset arrangement prevents the pins penetrating the secondary PCBs from penetrating the primary PCBs in the same manner. This offset configuration thereby avoids significant flashover problems associated with current planar components. Moreover, the invention describes an arrangement whereby a jumper or other connection can be used to connect the windings in a series or in a parallel configuration allowing the user to configure the component according to user-required parameters.
Abstract:
The present invention relates to a stepwise adjustable attenuator especially for use in volume control of audio-signals in amplifier systems and generally for attenuation of electrical signals in other appliances. The new solution provided according to the present invention consists of the electric resistors being surface-mounted devices (SMD resistors) which are mounted quite close to the wafer terminals. Hereby the series-inductance, the stray capacitance, the distortion, the length of the signal-path and the interference of electric fields from noise sources are decreased and as a result of this the attenuator's bandwidth for the electrical signal frequencies is increased and the compact design is advantageous in new designs as well as for upgrading existing appliances.
