Abstract: A method, apparatus, and computer-usable medium for compressing data in a file system utilizing the concept of "holes". A mapping table in a file system maps the logical blocks of a file to actual physical blocks on disk where the data is stored. Blocks may be arranged in units of a cluster, and the file may be compressed cluster-by-cluster. Holes are used within a cluster to indicate not only that a cluster has been compressed, but also the compression algorithm used. Different clusters within a file may be compressed with different compression algorithms. A unit of data is compressed, with the result that the file occupies fewer physical blocks than it has logical blocks. The mapping table is updated to indicate that for a given unit of data compressed, fewer physical blocks are needed. Certain logical blocks belonging to this unit of data are not mapped to physical blocks but are mapped to a hole.

Abstract: A method of fabricating a semiconductor structure utilizing doped silicate glass on a substrate of a wafer. The method includes the step forming a modulation doped silicate glass structure over a first layer of the wafer. The modulation doped silicate glass structure is formed by depositing at least two alternating layers of heavily-doped silicate glass and lightly-doped silicate glass over the first layer. Both the heavily-doped silicate glass and lightly-doped silicate glass layers may comprise glass doped with both a first dopant and a second dopant. The first dopant may represent, for example, phosphorous, and the second dopant may represent, for example, boron.

Abstract: A game method and apparatus includes a playing surface having a player end and a target end and a target provided at the target end. The target includes a channel on a planar target surface that is inclined and receives multiple playing pieces, such as balls, rolled across the playing surface by the player. The channel receives balls in a known configuration, such as a linear stack, such that each additional ball is directed to the channel with greater difficulty by the player due to the presence of previously-directed balls in the stack and rests on the ball immediately preceding it. The channel includes parallel rails for aligning the balls and for preventing the balls from touching the target surface. An aperture collects balls that are not received by the channel and routes the balls to the player. A release device releases the balls from the channel and into the collector. A game score and optional progressive score are based on the positions of balls in the channel.

Abstract: A method and apparatus for interfacing the motion of an object with a digital processing system includes a sensor which has a sensing resolution and detects movement of the object along a degree of freedom. An amount of play less than the sensing resolution exists between the sensor and the object. A passive actuator is coupled to the mechanism to transmit a resistive force to the object along the degree of freedom. A play mechanism is coupled to the actuator to provide a desired amount of play between the actuator and the object along the degree of feedom. The desired amount of play is greater than the sensing resolution of the sensor so that the sensor can detect the desired play when the user moves the object, even when the actuator has locked the object into place. Such desired play can be torsion flex (compliance) or rotary backlash. The actuator and the sensor provide an electromechanical interface between the object and the digital processing system.

Abstract: A resistive load structure and method for making a resistive load structure for an integrated circuit includes the use of an amorphous silicon "antifuse" material.

The resistive load structure is advantageously formed by depositing an amorphous silicon pad over a conductive via, and the resistance of the resistive load structure is controlled by adjusting the thickness of the amorphous silicon pad and varying the diameter of the underlying conductive via.

Abstract: A method for monitoring contamination in a semiconductor wafer uses a capacitance-frequency measurement on MOS structures to calculate an impurity concentration. The silicon substrate along with an oxide layer is first biased into the inversion region using a variable frequency waveform generator superimposed upon a DC voltage bias. Next, the capacitance of the wafer is measured as a function of the varying frequency in order to develop a capacitance versus frequency curve. From this frequency response, a bandwidth (BW) is measured at a particular normalized capacitance point. The impurity concentration N is then derived using the formula N=G.times.BW, where G is the correlation constant. With an a priori knowledge of impurity concentration, N, the constant G may be derived by measuring a bandwidth of the capacitance versus frequency curve. Once the constant G is determined, future evaluation of impurity concentration can be made by a capacitance measurement.

Abstract: A cell pressure control system is disclosed which has a two stage control mechanism. In the first stage, increased cell pressure causes a conductive deflection member to bend to a position where it opens an electrical contact and places the cell in open circuit. This prevents current from flowing through the cell and thereby possibly slowing or preventing further increases in cell pressure. The electrical contact relies only upon the pressure of two members (one of which is the deflection member) pushing against one another. If the cell's internal pressure continues to increase even after the pressure contact is broken, the second stage of the pressure control mechanism is activated. Specifically, a pressure rupturable region in the above-mentioned deflection member ruptures to relieve the cell's internal pressure. The pressure rupturable region is a circularity scored region on the conductive deflection member.
