摘要： A method for reducing charge accumulation in a field emission display (100) includes the steps of causing a plurality of electron emitters (114) to emit electrons (132) to reduce the potential at an anode (124) of the field emission display (100). Upon the reduction of the potential at the anode (124), the electrons (132) neutralize a positively electrostatically charged surface (129) of a spacer (130). The anode potential is dropped by providing a resistor (127) in series with a voltage source (126) connected to the anode (124). The anode potential is reduced by causing the electron emitters (114) to emit simultaneously to provide a pull-down current (128) at the anode (124). The voltage at the anode (124) is reduced to a value that causes a sufficient flux of electrons (132) to be attracted to the charged surfaces (129) for neutralizing them.

摘要： A method for providing a gray scale in a field emission display (50) includes the step of providing a first driving pulse (214) having a pulse width equal to a pulse width separation (115) between the graphs (100, 200) of total charge response versus pulse width of a driving pulse for the non-ideal field emission display and the corresponding ideal field emission display. The pulse width separation (115) is the horizontal distance between the two graphs (100, 200) at a region wherein the two graphs (100, 200) are generally parallel. The pulse width, t.sub.n, of an nth driving pulse corresponding to an nth gray scale level is given by t.sub.n =t.sub.1 +[n-1]*[(t.sub.N -t.sub.1)/(N-1)], wherein t.sub.1 is the pulse width of the first driving pulse (214), N is the total number of gray scale levels, and t.sub.N is the pulse width of the Nth driving pulse.

摘要： 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.

摘要： 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.

摘要： 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.
