Abstract: The present disclosure relates to medicine delivery devices, as well as methods of delivering an aerosol medicine to a subject in need thereof. A benefit to the medicine delivery devices and methods herein can be the efficient delivery of an aerosol medicine to a subject in need thereof, thus helping to improve treatment outcomes, as well as avoiding wastage of expensive medicines. Additional benefits to the medicine delivery devices disclosed herein can be low cost, lightweight, compact, versatile, and simple to use devices useful for a wide range of patients and healthcare settings. Another benefit of the medicine delivery devices can be safer to use devices that can lower the risk of infection for patients and healthcare providers.

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 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.
