Abstract: A method of designing a metal mesh touch sensor with randomized channel displacement includes generating a representation of a first conductive pattern. The representation of the first conductive pattern is partitioned into a plurality of representations of column channels. A random channel displacement is applied to at least one column channel. A representation of a second conductive pattern is generated. The representation of the second conductive pattern is partitioned into a plurality of representations of row channels. A random channel displacement is applied to at least one row channel.

Abstract: A method of designing a metal mesh touch sensor with randomized pitch includes placing a first plurality of representations of parallel conductive lines oriented in a first direction with fixed pitch spacing between adjacent representations of parallel conductive lines oriented in the first direction. For each placed representation of a parallel conductive line in the first plurality of representations of parallel conductive lines oriented in the first direction, a first random offset amount within a predetermined randomization constraint is generated. The placed representation of the parallel conductive line is moved by the first random offset.

Abstract: A video test signal generator system with removable memory card and display provides a combination of a front panel display and a removable memory card in a video test signal generator. The memory card allows a user to program the generator in a number of configurations never before possible. The removable memory card can be used to store signal data which is used by the generator in producing test signals, signal selectio protocol and status information which is printed on the front panel display to indicate the generator settings.
