Abstract: A system for transmitting and receiving electromagnetic radiation includes a beam splitter and a transceiver. The beam splitter is configured to separate an optical pulse into a pump pulse and a probe pulse. The transceiver may include a transmitter switch and a receiver switch. The pump pulse is directed toward the transmitter switch and the probe pulse is directed towards the receiver switch. Electromagnetic radiation is emitted from the transceiver when the pump pulse strikes the transmitter switch. The electromagnetic radiation may be terahertz radiation in either a pulsed or continuous wave form.

Abstract: A cigarette rolling paper dispenser is adapted to store tip blanks for using in reinforcing the mouth end of hand-rolled cigarettes. The dispenser is formed from a generally rectangular blank of stiff card. Lateral hinge lines divide the area of the blanks into multiple panels. One sets of panels are configured to fold into a conventional rolling paper compartment. Another set of panels define an integrally connected set of tip panels. Longitudinal tear lines extending across all the tip panels divide each panel into a set of rectangular tear-off tip blanks. The tip panels fold into a compact accordioned stack, which locates conveniently with the dispenser, when the later is folded to a compact state.
