Abstract:
The keyswitch pad includes a plurality of keyswitches on a common backing member, each of the keyswitches including a fluid filled bag underneath a key cap. The bags of the keyswitches are interconnected and the system of bags is closed so as to be of limited volume so that only one keyswitch at a time can be depressed. Several different types of keyswitches can be used in any one switch pad and several types of switching, latching, and display mechanisms are disclosed for the keyswitches.
Abstract:
A low-friction device having a moving interface comprising first and second members. Each of the members has a maximum dimension of about 100 μm or less between any two points. At least the first member is formed of diamond and the first and second members are in sliding contact or meshing contact.
Abstract:
A data storage system that includes a positioning system for positioning the write/read mechanism and the storage medium of the data storage device with respect to each other in first and second predefined directions. The positioning system comprises a positioning apparatus comprising microfabricated first and second positioning assemblies. The positioning system further comprises a controller to position a positionable support structure of the first positioning assembly in a first predefined direction within a range of positioning that is larger, than the range of movement of a moveable support structure of the first positioning assembly by controlling (A) a stationary support structure clamp in clamping and unclamping the positionable structure to and from the support structure, (B) a moveable structure clamp in clamping and unclamping the positionable support structure to and from the moveable support structure, and (C) the movement of the moveable support structure. In one embodiment, one of the write/read mechanism and the storage medium is carried by the positionable support structure so that it is positioned with the first positioning assembly. The other one of the write/read mechanism and the storage medium is positioned with the second positioning assembly. In another embodiment, the positionable support structure carries the second positioning assembly and one of the write/read mechanism and the storage medium is positioned with the second positioning assembly while the other is held stationary. In several embodiments, the read/write mechanism is used:to mechanically write data to and electrically read data from the storage medium. In still another embodiment, the read/write mechanism is used to optically write data to and electrically read data from the storage medium. In yet another embodiment, the read/write mechanism is acoustically aided in electrically writing data to and reading data from the storage medium.
Abstract:
A scanning probe microscopy (SPM) inspection and/or modification system which uses SPM technology and techniques. The system includes various types of microstructured SPM probes for inspection and/or modification of the object. The components of the SPM system include microstructured calibration structures. A probe may be defective because of wear or because of fabrication errors. Various types of reference measurements of the calibration structure are made with the probe or vice versa to calibrate it. The components of the SPM system further include one or more tip machining structures. At these structures, material of the tips of the SPM probes may be machined by abrasively lapping and chemically lapping the material of the tip with the tip machining structures.
Abstract:
Techniques for affixing a micro-object to a mounting structure at a desired relative orientation. A shaped portion of a workpiece is caused to become embedded in a reference structure at a first relative orientation. The workpiece is parted into first and second portions, the first portion of which includes the embedded shaped portion of the workpiece and defines the micro-object. The reference structure is aligned with the mounting structure at a second relative orientation, the first and second relative orientations defining the desired relative orientation of the micro-object and the mounting structure. The micro-object is bonded to the mounting structure while the micro-object remains embedded in the reference structure and the reference structure remains aligned with the mounting structure at the second relative orientation. The micro-object is separated from the reference structure, whereupon the micro-object remains in the desired relative orientation with respect to the mounting structure. The micro-object may have dimensions less than 200 microns, and possibly on the order of 15-25 microns.
