Abstract: A terminal-protective card connector includes a shell and a pressing member. The shell includes at least two (first and second) groups of terminals mounted thereto, and two upright guiding portions formed at two internal sidewalls thereof. The pressing member includes two guided parts formed at two ends thereof and slidably mounted to the two guiding portions, a plurality of through holes formed therein, and at least one bevel formed at a front end thereof. The second group of terminals has contact portions running through bottom sides and then top sides of the through holes respectively to support the terminals of the second group. Thus, a specific group of terminals can be optionally pressed to avoid deformation or short circuit resulted from impact of or contact with uncorresponding cards to be protected.

Abstract: A variable intake system of a vehicle includes an intake manifold having a runner, an opening/closing part for varying the runner length of the intake manifold, an actuator for driving the opening/closing part, and a vacuum part forming a vacuum chamber for driving the actuator. The vacuum part is disposed on an upper portion of the intake manifold such that noise from the engine may be decreased.

Abstract: Displacement is measured using two overlaid parallel optic gratings as the sensing elements of a sensor head. Optic fibers are employed as the transmission media between the sensor head and a central signal processing unit. The light intensity signals of Moire fringes generated by the overlaid optic gratings are transmitted through optic fibers to the central signal processing unit. By digitally counting the number of Moire fringes, the changes in both direction and magnitude of the displacement are measured. A number of sensor heads employing the overlaid optic gratings as sensing elements are multiplexed through a common optic fiber link to comprise a multipoint sensor system. By similarly modifying the sensor head, this sensor system also measures other physical quantities such as strain, acceleration, and pressure.
