Abstract:
A MEMS incorporating a sensing element and a JFET electrically connected to the sensing element is fabricated by the steps of: forming a first layer of electrically insulating barrier material on a surface of a substrate; patterning the first layer so as to expose a first region of the substrate; doping by ion implantation the first region of the substrate to form a well region of the JFET; forming a second layer of barrier material on the surface of both the first layer and the first region of the substrate; patterning the barrier material so as to expose a part of the first region of the substrate; doping by ion implantation the exposed part of the first region of the substrate to form source and drain contact areas of the JFET; patterning the barrier material so as to expose a second region of the substrate; and doping by ion implantation the second region of the substrate to form gate and substrate contact areas of the JFET in a single implantion step. The monolithic integration of the JFET with the MEMS enables the bond wires for interconnecting the sensing element and the associated sensing electronic circuitry to be provided only after the buffering stage of such circuitry. This means that the bond wires interconnecting the buffering stage and the remainder of the circuitry are connected to a low impedance node which is less sensitive to noise and parasitic capacitive loading. Thus greater detection accuracy can be achieved by virtue of the fact that the parasitic capacitances are reduced to a minimum.
Abstract:
Mechanisms and techniques for database fragment cloning and management are provided. A database object, such as a table, rowset or index, is divided into fragments. Each fragment is cloned to create cloned fragments, which operationally are substantially identical to one another. One or more of the cloned fragments may be designated as a primary cloned fragment for performing database operations or as a secondary cloned fragment for serving as backup. Updates to each fragment are implemented on the primary cloned fragment and are then propagated from the primary cloned fragment to the corresponding secondary cloned fragments. A cloned fragment can go offline, becoming unavailable to be updated. When the cloned fragment returns online, the cloned fragment is refreshed with data included in the primary cloned fragment. While being refreshed, the cloned fragment may continue to be updated. The cloned fragment is eligible to be designated as a primary cloned fragment when the refreshing process has been completed.

Abstract:
A method of consolidating genealogy records includes partitioning the records using at least one index file to form one or more partitions, sorting the records in a partition based on a data element in the records, comparing records within a sort range, based on the comparison, identifying same person records, consolidating information in the same person records, receiving a request from a user to view at least a portion of the consolidated information for a particular group of same person records, and sending a file that includes the portion to the user.
Abstract:
A system and method for controlling a damping system. The system has at least two dampers for damping between sprung and unsprung masses in the compression and rebound directions. Sensors generate signals based on position and other parameters of motion representative of the displacement between the sprung and unsprung masses. The process determines the appropriate compression and rebound forces to be applied at the wheels. A regulator responds to at least one of the independent compression and rebound control signals for adjusting, respectively, at least one of compression and rebound resisting forces of the dampers between the masses. Compliance for the dampers is emulated with software to produce the desired compliance forces. The distributed controller includes a processor that is responsive to signals representative of the position signals for forming the compression and rebound control signals for the regulator as a function of motion between the masses or a motion of a vehicle in which the dampers are located. The system has the capability of locking the suspension when parked.
