A pressure-energized seal for a spring-type brake actuator for a vehicl e brake, in which the actuator's power spring is located between the service brake actuator and parking brake release actuator. The power spring is captured between the actuator's intermediate flange and a spring retainer. In order to preven t pressure leakage past the spring retainer into a power spring cavity, a pressure-ene...

A network for combat control of ground-based units, such as combat vehicles, in real time, may obtain information is concerning the units comprised in the network for the evaluation of threats and the calculation of a response. The units may be divided into clusters with a central unit in each cluster and at least one client unit in each cluster, which client units are arranged to communicate with...

A system for controlling the operation of a printing press used to apply an aqueous printable electrically conductive ink onto a substrate to create electrically conductive traces of such ink includes a probe for contacting the electrical traces and for obtaining a resistance measurement therefrom. A computer receives the resistance measurement, compares such measurement with pre-selected data cor...

On a world basis, thousands of handballs are discarded every year after a relatively short lifetime (approx. 1 -1 ½ years) as a consequence of the use of resin by the players. The players use the sticky resin to improve their grip on the ball. But "smearing" of the ball in resin has the result that dirt and dust from the floor adheres to the ball. Therefore, a crust of these materials is formed re...

A semiconductor chip packaging structure comprising a dielectric film 1 0 having one or more through holes 11 aligned with the one or more contact pad s 22 and 23 of at least one power semiconductor chip 21. A patterned electrically conductive layer 40 adjacent to the dielectric film 10 has one or more electrically conductive posts 41 which extend through the one or more though holes 11 aligned wi...
