Abstract: A force measuring device and method for determining a force required to move a cart. The force measuring device includes a force generating device, a load member, a load cell, and a controller. The force generating device is connected to the load member and moves the load member toward or away from the cart so as to apply pushing or pulling forces to the cart. The load cell is disposed between the load member and the cart, and transmits sensed force data to the controller. During a test, the controller collects the force data from the load cell. By testing carts of various configurations under all expected loading conditions, the performance of each cart configuration can be experimentally determined. The performance data is assembled in a database to permit a user to identify an optimum cart for an intended application.

Abstract: A digital video word (14) that is utilized to specify an image to be displayed by a field emission device is divided into a plurality of digital subwords (16, 17). Each digital subword (16, 17) is utilized to create a control signal (21, 22) that is applied to an input (23, 26, 32, 33) of a drive source (24, 27, 31). The digital subwords (16, 17) divide the control signals (21, 22) into time slots wherein each time slot has a duration that is greater than the duration of time slots represented by the original digital video word (14). In response to the control signals (21, 22) the drive source (24, 27, 31) provides a drive signal (28, 34) that has an output value and duration that is controlled by the duration of the control signals, and by an active and inactive state encoded by the control signals.

Abstract: A zero insertion force electrical connector for electrically connecting two electrical members. A plurality of first electrical contacts on a first member engage a plurality of second electrical on a second member. An isostratic medium is retained against the second member and a pressure generator acts on the isostatic medium for providing a uniform force forcing the first and second contact into engagement. One of the first and second contacts may be positioned in recesses and the other of the first and second contacts are outwardly extending for providing self-alignment between the first and second members. The second member may be a three-layer tape having a first metal signal layer, a middle dielectric layer and a second ground layer for interconnection to a third electrical member.
