Abstract: Filter racks are disclosed that are adjustable to accommodate filters of various thicknesses. The filter racks may include an insert that can be positioned within the base of the filter rack in two or more positions to adjust the receiving width of the filter rack. A perforated tab of the insert may be unbent to position the insert within the base at a smaller width, and the tab may be bent to position the insert within the base at a larger width. The insert also may include a divider that can be positioned within the base to reduce the width of the filter rack. Further, a rotating guide may be attached to detents within walls of the filter rack compartment. The guide may be biased at various angles to accommodate filters of different widths.

Abstract: The present invention provides an adjustable crash stop. The stiffness or load of the crash stop may be varied by rotating the stop and thereby varying the point of contact between the actuator assembly and the crash stop. The point of contact is on an arcuate contact surface of a cantilever supported spring. The spring is supported by a stem that can be positioned in several different rotational positions such that the contact point is at different locations on the contact surface. The stiffness at each contact point changes as its distance from the hinge point of the spring changes.

Abstract: Method and apparatus for providing strain relief for an electrical connector, such as an edge connector affixed to a printed circuit board (PCB). The connector includes a dielectric body which supports a number of electrical contacts each having a proximal end configured for electrical and mechanical engagement to a device, preferably via a soldering operation. One or more strain relief clips are inserted into associated recesses formed in the body of the connector. Each strain relief clip is configured for attachment to the device using a solder connection to relieve strain forces upon the electrical contacts upon installation of the connector onto the device. As desired, advanced ground contact functions can further be incorporated into the strain relief clips.

Abstract: A magnetic disc drive includes a base, a disc rotatably attached to said base, and a ramp attached to the base near said disc. The magnetic disc drive also has an actuator assembly pivotably attached to the base. The actuator assembly rotates about an actuator pivot point. The actuator assembly further includes a suspension attached to one end of the actuator assembly, and a transducer attached to the suspension. The actuator assembly moves the transducer between a transducing position and an unload position. The suspension includes a lift tab which contacts the ramp at a contact point as the transducer is moved to the unload position. As the actuator assembly moves the transducer to the unload position, the contact point moves toward the actuator pivot point. This results in a change of the resonant frequency of the actuator assembly. The resonant frequency is lower when the transducer is near the end of the ramp proximate the disc. The ramp can have a straight or a curved lift tab contact path.
