摘要:
A slider includes a Tunneling Magneto-Resistive (TuMR) read sensor and a shunt resistor connected in parallel. The shunt resistor may be located in a read structure of the slider. The shunt resistor may reduce a total resistance of the read structure and any corresponding impedance mismatch between the read structure, a transmission line, and a preamplifier. The shunt resistor may be made of a material having a near zero thermal coefficient of resistivity (TCR) to test a quality of the TuMR read sensor. The TuMR read sensor may be deemed defective if its TCR deviates from a population average by a specific criterion. The TuMR read sensor may include a MgO tunneling barrier to improve signal strength. The TuMR read sensor may include a free layer that is able to be saturated with a perpendicular background field to calculate a more accurate TCR of the TuMR read sensor.

摘要:
The present invention provides operators the ability to follow a predetermined path and achieve desired digging depth by watching steering and elevation indicators of just one system. The indicators are activated by data derived from the interception of signals generated by a single laser transmitter and a receiver array mounted on the machine. The system according to the present invention uses the multiple, tilted fan beams provided by the laser transmitter to calculate elevation angle and azimuth of the tool carried by machine.

A geographical position/image capturing system stores object images and position coordinates as digital data. The system incorporates a geo-addressed map data base and geo-positioning device for relating the position of the system at the time the image is captured to the captured digital image data and the geo-addressed map. A point-of-interest feature data base is linked to the image data and the position data, by hyper-media links. Digital multi-media entities such as graphics, video clips, audio streams and the like can be digitally stored and retrieved based on hyper-media links coupling the entities to the object images, the map position and feature data base. A playback unit incorporating an image viewer communicates with the stored digital digital image data, the multi-media entities, the map data base, and the feature data base and allows modified images of selected portions of the images and other data to be viewed by a user. An audio reproduction device may be included to reproduce the audio media entities when they are selected by the appropriate hyper-media link. In one embodiment of the system, the image capturing function and the geo-positioning function are physically remote from the viewing function until the captured data is transferred to the retrieval and playback unit. In another embodiment, the capture functions and playback functions are combined in a compact, hand-held, portable unit for consumer or industrial field use. The images, position data and multi-media entities may be stored as a single, compressed, linked digital data file. The data file is provided with hyper-media connections between the various entities, which connections are actuated by clicking on icons displayed on the viewer, or by actuating buttons or switches provided on the system console. Angular orientation determining device for providing angular orientation data may also be incorporated such that the system angular orientation at the time of image capture may be captured and stored for subsequent retrieval and display.

A loader and a control system for a loader provide for monitoring the position of a part of the implement carried by the loader. The loader has a body with left and right upright tower portions, and a loader drive system including ground engaging drive elements. Left and right interconnected lift arm assemblies each have an implement lift arm pivotally connected with a corresponding tower portion of the body at a lift arm pivot point. A lift actuator is connected between the body and the lift arm. The implement is pivotally connected with the lift arm assemblies about an implement pivot axis. The lift arm pivot point and the implement pivot axis in side elevation define a straight reference line. At least one implement tilt actuator is connected between at least one of the lift arm assemblies and the implement. A position sensor is mounted on the body at the level of, or above, the lift arm pivot points. An inclinometer is movable with the left and right interconnected lift arm assemblies to provide an indication of the inclination of the lift arm assemblies along the straight reference line. An angle sensor provides an indication of the orientation of said implement with respect to said left and right interconnected lift arm assemblies. The control is responsive to the position sensor, the inclinometer, and the angle sensor. The control determines the position of the position sensor and the position of a part of the implement with respect to the position sensor.
摘要:
In one aspect, the invention provides a random or semirandom siRNA (encoding) library. Another aspect of the invention pertains to methods for construction of random or semirandom siRNA (encoding) libraries. Another aspect of the invention is vector systems for use in constructing siRNA libraries and/or that can express single siRNAs and siRNA libraries both constitutively and in an inducible fashion. In another aspect, the invention provides a method of using an siRNA library. The siRNA library is introduced into a population of cells. The population of cells then is subjected to a selection process to select a subpopulation of cells exhibiting a different behavioral, biochemical, chemical, functional, molecular, morphological, phenotypic, or physical property from the remainder of population. Following the selection process, the subpopulation of cells can be isolated, analyzed, and/or cloned as desired. Such analysis of the subpopulation can be identification and sequencing of the siRNA species responsible for the different properties of the subpopulation relative to the remainder of the population. Alternatively, the subpopulation can be further analyzed by genomic, proteomic, and/or cellomic assays. Where such genomic, proteomic, and/or cellomic assays are employed, the method can produce several useful bioinformatics products. Specific siRNAs identified through this process may have direct therapeutic value.
