A computer-implemented system and method for interactively displaying static or real-time streaming multivariate data onto a 2D computer display, via virtual reality, mixed reality, augmented reality or holographic display hardware, or manufactured using hardware such as a 3D printer.

System and method for experiencing higher dimensionality data using lower dimensionality media

Compression of a plurality of signal samples y(t.sub.0),y(t.sub.1),y(t.sub.2) . . . y(t.sub.z) may be accomplished by performing a first linear regression to obtain a curve fitted thereto which is represented by a polynomial having a first set of coefficients (a.sub.0,a.sub.1,a.sub.2,a.sub.3 . . . a.sub.n) which is stored in memory (18) or transmitted by a transmitter (20). The error between each of the actual signal samples (y(t.sub.0),y(t.sub.1),y(t.sub.2) . . . y(t.sub.z) and the value approximated by the curve fitted to the values is computed and then thresholded. A second regression analysis is then performed to fit a curve, having a second set of coefficients (b.sub.0,b.sub.1,b.sub.2,b.sub.3 . . . b.sub.q) to the thresholded error values. The second set of coefficients is also stored or transmitted and used, in conjunction with the first set of coefficients, to closely approximate the original set of signal samples.

The state of charge of a rechargeable battery (12), such as those made from lithium, nickel-cadmium or metal hydrides, can be accurately determined by monitoring the rate of change of battery voltage over time (dv/dt), which parameter has empirically been found to change dramatically as the battery reaches complete discharge.

A multi-fastener assembly tool (10, 10' and 10') for engaging at least one threaded fastener (14) for securing the fastener to a threaded stud (20) includes a member (26) having a fastener locating and holding mechanism (27) at one end. The fastener locating and holding mechanism is adapted to be squeezed through the fastener to retain it on the member. The member is seated within, and is springbased from, a circumferentially disposed socket (32) sized to engage the fastener. A shaft (42), having a handle (44) at one end, is integrated to the socket to allow a force to be applied to urge the socket against the member once the fastener locating and holding means are aligned with the stud. As the socket is urged against the member, the threaded fastener is seated in the socket and is then pushed off the member to the stud. Once the fasteners is at the stud, a rotational motion is imparted to the handle to thread the fastener onto the stud.

An electronic game (10) is provided with at least one, and preferably a plurality, of intelligent game pieces (14,14' ) which each contain a re-programamble memory device (30,70). The memory device (30,70) in each of the game pieces (14 and 14', respectively), stores characteristics of an activity to be simulated by the game (10). By re-programming the game pieces (14,14'), the characteristics of the activity simulated by the game (10) can be changed to make the activity more interesting and challenging.
