A system and method for detecting the position of an object are disclosed. The new and distinct variety has high ornamental value, cold tolerance for short periods of time, and disease resistance. As the compounds of the present invention have superior antibacterial activity and pharmacokinetic profiles to their enantiomers, their racemates and conventional antibacterial agents, with nearly no phototoxicity, the compounds of this invention are useful for antibacterial agents. In one aspect of the invention, protective elements may be mechanically secured to a matrix by a puncture and crimp process. The communication device provides overt communication alerts for incoming communications from overt communication sources. A diagnostic device on which the method according to the invention can be implemented in one of its embodiments is also proposed, as is a corresponding key module, and also a diagnostic system which comprises a diagnostic device and at least one key module.
