A method for exciting an antenna with a waveform having a burst width and pulse width scaled proportionately with a selected range scale and a temporal filter to address any ambiguities in range resulting from the transmission of a signal in accordance with the novel waveform. The set of rollers includes a number of rollers rotating about respective roller shafts which are connected to the vertical shaft via a hinged connection which has a bearing shell and a bearing journal resting therein. The security appliance utilizes the network address of the industrial device when communicating with a management server and is addressed by the management server using the address of one of the protected devices associated with the appliance. A damper suspending the bobbin is composed of a corrugation portion, which is positioned orthogonal to the bobbin in an inactivity of the speaker apparatus. The pitch between adjacent elongated structures is less than 300 nm and the width of each elongated structure is less than 90% of the pitch. Also provided are opto-electronic cards and printed circuit boards which incorporate structure providing for the passive alignment of VCSELs to waveguides.
