An animated novelty device for mounting on a ball of a trailer hitch on a vehicle, the device including an electric motor for imparting motion to selected elements of the device. The medicament is typically contained within a cartridge located within the injection device. To achieve this purpose, specifically, to adjust a parallelism of a probe card that holds a plurality of probes for electrically connecting a wafer as a test object and a circuitry for generating a signal for a test with respect to the wafer, adjusting screws as at least part of an inclination changing unit are provided. The top deck has a central section and opposite end sections. A flexible sleeve in the sheathing assembly has a distal end, which is fixed to the sleeve dispenser, and a proximal end, which is adapted to engage the endoscopic tool as the endoscopic tool is retracted from the working channel, causing the sleeve to extend out of the dispenser in a proximal direction so as to sheath the endoscopic tool. The system further derives a value for the document based on the detected associations and uses the derived value in evaluating a quality of the document with respect to one or more subsequent queries.
