Inhalers with an inhaler housing having a dose container disk having inner and outer perimeters mounted in the housing. In an embodiment, an image is divided into a plurality of slices, each slice having the same width as the image. For each received first spread spectrum signal, a second spread spectrum signal is transmitted having an associated code having a same phase as that received first spread spectrum signal. The plurality of first datastreams are then mixed to generate at least one second datastream. The alignment structure permits only linear axial tension to be applied to the load cell in response to application of a further tension load on the load cell.
