system configured to detect whether a receptacle is seated in the puck. ### Claim 8 (depends on 4) The system of claim 4, wherein the puck includes a first passageway that extends transverse to and is offset from a vertical axis of the puck. ### Claim 9 (depends on 8) The system of claim 8, further comprising a sensing system configured to detect (a) whether a longitudinal axis of a receptacle seated in the puck is inclined with respect to the vertical axis of the puck, and/or (b) whether a receptacle seated in the puck is inserted to a desired depth in the puck. ### Claim 10 (depends on 9) The system of claim 9, wherein the puck is rotatably supported in a housing of the carriage, and wherein the housing includes a second passageway that extends transverse to and is offset from the vertical axis of the puck. ### Claim 11 (depends on 10) The system of claim 10, wherein the sensing system comprises a signal emitter and a signal detector, and wherein when the first and second passageways are aligned, the signal detector is configured to receive a signal from the signal emitter through the aligned first and second passageways when a receptacle is not seated in the puck. ### Claim 12 (depends on 11) The system of claim 11, wherein the signal emitter is an optical emitter, the signal detector is an optical detector, and the signal is an optical beam. ### Claim 13 (depends on 12) The system of claim 12, wherein when the first and second passageways are aligned, (a) the optical emitter is configured to direct the optical beam on an incident area on an external surface of a receptacle seated in the puck and (b) the optical detector is configured to receive at least a portion of the optical beam from the optical emitter if a receptacle is not seated in the puck, wherein if the receptacle is properly seated in the puck, the incident area is offset from a longitudinal axis of the receptacle. ### Claim 14 (depends on 13) The system of claim 13, wherein if a receptacle is properly seated in the puck, the incident area is offset from the longitudinal axis of the receptacle by a distance of from about 3 mm to about 6 mm. ### Claim 15 (depends on 13) The system of
