Abstract: A method and apparatus for detecting and computing tape reel radius using low-resolution angular position sensors is disclosed. Tape reels are driven at a constant velocity, a complete resolution of the tape reels is detected using coarse commutation sensors and a radius for a first reel, R1, and a radius for a second reel, R2 is calculated according to: R1=((L*T/pi)/(1+T22/T12))0.5 and R2=((L*T/pi)/(1+T12/T22))0.5, where L is the total length of tape, T is the thickness of tape, T1 is the rotation time for reel 1, and T2 is the rotation time for reel 2. The calculation of the radius of the two reels using two low resolution (one pulse per turn) sensors results in a great cost and product packaging savings.

Abstract: Test pages for an object oriented program on a web server are generated. A data structure is analyzed for a set of data fields. Rule data is retrieved from a rule database for property naming rules. Using this information, a test page, e.g., in HTML, is generated for each object associated with the data structure, the test page including an instance of the respective object and a set of property names and associated data names for the respective object. When a change is detected in the data structure, an updated set of test pages and test data can easily be generated to reflect the changed data structure. Dynamic argument generation and object constructors for test data and real data are encompassed by the invention.

Abstract: A technique for making acicular, branched, conductive dendrites, and a technique for using the dendrites to form a conductive compressible pad-on-pad connector are provided. To form the dendrites, a substrate is provided on which dendrites are grown, preferably on a metal film. The dendrites are then removed from the substrate, preferably by etching metal from the substrate. The so formed dendrites are incorporated into a compressible dielectric material, which then forms a compressible pad-on-pad connector between two conducting elements, such as connector pads on electrical devices, e.g. an I/C chip mounted on a substrate, such as a chip carrier.

Abstract: A microprocessor, data processing system, and an associated method of executing microprocessor instructions and generating instruction fetch addresses are disclosed. The microprocessor includes an instruction fetch unit comprising and instruction fetch address register (IFAR) and an instruction processing unit (IPU). The IFAR is configured to provide an address to an instruction cache. The IPU is suitable for receiving a set of instructions from the instruction cache and for generating an instruction fetch address upon determining from the set of instructions that the program execution flow requires redirection. The IPU is adapted to determine that the program flow requires redirection if the number of branch instructions in the set of instructions for which branch instruction information must be recorded exceeds the capacity of IPU to record the branch instruction information in a single cycle.

Abstract: A ground from a printed circuit board to the frame of an electronic system is formed by a biaxially-compressible conductive spring that is captivated between the printed circuit board and a plastic stiffener to which the board is fastened. The spring makes contact with a ground pad on the underside of the printed circuit board. As the board is fully installed in the electronic system, standoffs attached to the system frame make contact with the conductive spring, completing the ground path. Keyhole-shaped cutouts in the printed circuit board secure the board without the use of tools. When the board assembly is lowered onto the standoffs, the head of the standoff passes through the circular opening of the keyhole. The board assembly is secured in place by sliding it on the standoffs to a position in which the head of the standoff is over the narrower slot portion of the keyhole.

A probability calculator is included in the command predictor for determining a probability for each of the at least one next command based on the command history such that a list of predicted commands and their likelihood of being a next command are provided.

Abstract: Disclosed is a method and computer program device for dynamically managing the assignment of alias addresses to base addresses referencing an input/output (I/O) device, such as a direct access storage device (DASD). Two distinct methods are disclosed. In one method, alias addresses are assigned based on the performance of the I/O devices. In this method, alias addresses are assigned to highly utilized devices, as indicated by device performance data, in order to maximize the efficient utilization of I/O device resources. In a second method, workload management principles are utilized to assign alias addresses. In this method, a correlation is made between each I/O device and the service classes utilizing each device. As in the first method, performance data is generated for each I/O device. Alias addresses are assigned to I/O devices experiencing queue delays as indicated by their performance data, if the device is associated with a service class that has failed to meet one or more processing goals.

The preferred embodiment tracks which people are in which segment at each time period, then builds a file that gives, by person, a description of which segment(s) each person belonged to during each time period. From this table, a display is drawn which indicates in an intuitive manner the migration of members of different segments over time. These enhanced segmentation analyses allow the user to easily study and predict customer behaviors.

Abstract: A method, system, and program product for creating a child node of a binary space partitioning (BSP) tree node that better approximates the size of an object to be rendered is provided. In one embodiment, a a binary space partitioning tree is created. A rendering process then determines whether either a top node or a child node in a first level of child nodes is a good approximation of the object to be rendered. If not, then the rendering process modifies the binary space partitioning tree to include a new child node having boundaries that are closer to the maximum coordinates of primitives defining the object than are the boundaries of the top node or of the child nodes in the first level of child nodes. This new child node may have a bounding volume that overlaps the bounding volumes of other child nodes in the BSP tree.

Abstract: A high density printed wiring board is prepared by applying an essentially solid material into plated through holes such that the metallized layers within the through hole are unaffected by chemical metal etchants. In this manner, lateral surface metallized layers can exclusively be reduced in thickness by use of said chemical agents. These thinned lateral surface metallized layers are ultimately converted into fine pitch, 25 to 40 microns, circuitry, thereby providing high density boards. Since the through hole wall metallization is unaffected by the etching process, excellent electrical connection between the fine line circuitry is obtained. Various printed wiring board embodiments are also presented.
