Abstract: A braking system for an automotive vehicle is provided herein. The braking system includes a brake operating member, a booster including an input rod and operable to boost a brake operating force acting on the brake operating member. A master cylinder is provided for producing a hydraulic pressure on the basis of an input force received from the booster as a result of boosting of the brake operating force by the booster. A wheel brake cylinder is activated by the hydraulic pressure which is produced by the master cylinder, to brake a wheel of the automotive vehicle. The brake system includes a connecting member connecting the brake operating member and the input rod to each other. It is configured so as to permit a relative movement between the brake operating member and the input rod of the booster in an axial direction of the input rod by a predetermined maximum distance. A pivotal member is connected to the brake operating member such that the pivotal member is configured pivotal about an axis which is perpendicular to the axial direction of the input rod, on the basis of the relative movement between the brake operating member and the input rod. A booster-diagnosing device is provided for detecting an input and an output of the booster, and for determining that the booster is abnormal, if the detected input and output do not meet a predetermined nominal relationship therebetween. The booster diagnosing device includes a signal generating device fixed either to the brake operating member or the pivotal member. The signal generating device is configured to operate in response to a relative movement between the brake operating member and the pivotal member which is caused by the relative movement between the brake operating member and the input rod. The signal generating device generates an output signal relating to the brake operating force as the input of the booster, depending upon the distance of the relative movement between the brake operating member and the input rod.

Abstract: An RF power transistor package (10) is configured for mounting to a heat sink in a multi-layer pc board, and includes a direct top side electrical ground path from a transistor chip (16) located atop a ceramic substrate (18) to a mounting flange (30), without passing through the ceramic substrate, e.g., by way of metal plating an outer surface of the ceramic substrate to electrically connect a top mounted metal lead to the flange. A direct ground path from the transistor chip to the mounting flange is also provided by way of plated via holes (34) through the ceramic substrate. The top side ground path is also configured to connect with the middle ground reference layer of the multilayer pc board when the mounting flange is secured to the heat sink, so that a unified ground potential is seen by the transistor at both the middle layer and heat sink. In this manner, the power transistor package is grounded at the same reference potential as other elements attached to the pc board, while still having the high performance characteristics provided by the ground path via holes.
