Abstract: A method for evaluating for the presence of the COVID disease by detecting one or more biomarkers using a breathalyzer. The breath sample taken from the subject is passed over a sensor which changes resistance in the presence of nitric oxide as a function of concentration. The resistance pattern of the subject having the COVID disease will have a distinct shape, approximating the appearance of the small Greek letter omega (?). Test results can be generated in less than a minute.

Abstract: A method for evaluating for the presence of the COVID disease by detecting one or more biomarkers using a breathalyzer (138). The breath sample (2) taken from the subject (10) is passed over a sensor (140) which changes resistance in the presence of nitric oxide as a function of concentration. The resistance pattern of the subject (10) having the COVID disease will have a distinct shape, approximating the appearance of the small Greek letter omega (?). Test results can be generated in less than a minute.

Abstract: A system (10) for attaching a trailing device (12) to a vehicle includes a bumper assembly (11) having a back structure (13) which carries an energy absorbing module (14). The system (10) includes receiver assemblies (60) which are attached to the bumper back structure (13) and which include a tube (62). The system (10) also includes carrier assemblies (40) which carry the trailing device (12) and which each includes an arm end (42) slidably received in the tubes (62). Shear pins (73) attach the arm ends (42) to the tubes (62) and upon impact to the trailing device (12), a leg (74) of each pin (73) can be sheared allowing relative movement between the arm ends (42) and the tubes (62). As a result, the carrier assemblies (40) contact the energy absorbing bumper module (14) to absorb some of the energy of the impact.
