Methods and devices are described for operating an input device for an electronic system which includes a housing. The input device includes an input surface and a first substrate having a first plurality of sensor electrodes configured to sense input objects proximate the input surface, and a pair of force sensing electrodes on the bottom of the first substrate. The input device includes a second substrate having a planar spring plate including a perimeter region surrounding an interior region, the perimeter region including a leaf spring coupled to the housing, and a spacing layer configured to physically couple the interior region of the second substrate to the first substrate. A force applied to the input surface deflects the first substrate and the interior region relative to the perimeter region, changing a variable capacitance formed between the force sensing electrodes.

Force enhanced input device

An input device for fingerprint sensing and proximity sensing includes a cover layer, where a top surface of the cover layer is configured to provide an input surface for a finger, a substrate having a cavity disposed below the cover layer, and a fingerprint sensor disposed below the cover layer and in the cavity of the substrate. A first adhesive layer is disposed between a top surface of the fingerprint sensor and a bottom surface of the cover layer in a fingerprint sensing area. A second adhesive layer is disposed between a top surface of the substrate and the bottom surface of the cover layer in a proximity sensing area.

A key assembly is for use in a keyboard of the type including a key guide having a planar translation effecting (PTE) feature. The key assembly includes a key base having a PTE mating feature configured to interact with the PTE feature during a key press, and a key cap configured to be attached to the key base. The key base is made of a first material and the key cap is made of a second material different from the first material. A conductive portion and/or a magnet may be wedged between or secured within the key base or the key cap.

Disclosed are systems and methods for reducing vibration in a device mounting structure, the method including determining when the vibration level of the device mounting structure exceeds a first threshold, and reducing the data transfer rate of at least one data transfer device mounted to the device mounting structure an amount sufficient to reduce the vibration to a level below a second threshold.

System and method for controlling vibration

An apparatus in one example comprises a card guide that provides an installation path for an extension circuit card. The installation path promotes a coupled relationship between the extension circuit card and a circuit board. The card guide comprises a first connector and a second connector. To form the coupled relationship the extension circuit card attaches to one of the first connector and the second connector based on a configuration of the extension circuit card.

The present invention comprises a body for accommodating and optical fiber in a disk drive.

Variable length self-retaining optical fiber spool

An apparatus designed for the testing of a micro-machined mirror that is mounted onto a flying optical head is described. As in the case of normal operation of the head, laser light is coupled into the head using an optical fiber. The light propagates through the head, is emitted from the fiber, reflects off of the steerable mirror inclined at 45 degrees to the fiber axis, and passes through a focusing lens and exits the head. A position sensitive detector (PSD) is placed so as to detect the position of the light spot as it exits the head. Actuation of the mirror's steering capabilities modulates the spot position, which is detected by the PSD and its associated electronics. The profile of the PSD is made small enough to fit in a space between two opposing optical heads on a head stack assembly (HSA) so that the test can be performed immediately prior to the assembly of the disc drive. An array of such PSD's is constructed so that all of heads on an HSA can be tested simultaneously or in a multiplexed manner.
