Abstract: The present invention discloses a handheld medical device having a housing, at least one user activatable button mounted on a surface of the housing, and a light source mounted within the housing below the button and arranged to direct light towards the button. Substantially the whole of the button and the surface of the housing adjacent the button are opaque, save for a narrow strip adjacent the periphery of the button which is non-opaque.

Abstract: The invention resides in a hand-held medicament delivery device having a housing in which is mounted, a switch, an electro-mechanical drug delivery mechanism activatable by the switch and a dose button associated with the switch. When the dose button is pressed by a user, the switch is activated. Furthermore, the dose button is hinged along one edge thereof. The dose button may be hinged about a support element of the housing or integrally formed with at least a part of the housing, a line of weakness such as a thin walled region being provided between the housing and the dose button to serve as the hinge.

Abstract: In order to transmit information relating to vehicle or vehicle component testing or monitoring at a test site, the test information is processed for example in a computer memory and the resulting image signal is sent via a transmission medium to a remote terminal where it is reconstructed. As a result only the image signal is sent requiring reduced bandwidth.
