Abstract: A docking system for assisted boat docking. The docking system may include a front assembly and/or a rear assembly. The front assembly can be configured to engage a bow of a boat and at least partially absorb a docking impact force of the boat. The front assembly can include a first mounting portion, a first arm, and a bow retaining portion. The first mounting portion can be configured to be supported by an upper surface of a dock. The first arm can be supported by the first mounting portion and can extend transverse to the first mounting portion. The bow retaining portion can be supported by the first arm. The rear assembly can be configured to engage and/or secure a rear of the boat to the dock.

Abstract: A docking assist assembly for assisted boat docking. The docking assist assembly may include: a mounting portion configured to be supported by an upper surface of a dock; an arm portion extending transverse to the mounting portion; and a bow retaining portion including a first side defining a first surface facing at least partially toward the second side and a second side defining a second surface at least partially facing toward the first side, said first side and said second side configured to receive a bow of a boat at least partially between the first side and the second side; wherein at least one of the arm portion and the bow retaining portion is movable relative to the mounting portion so as to at least partially absorb a docking impact force of a boat.

Abstract: A variable rate particle counter for adjusting the volumetric delivery rate of fluid to a flow cell based upon an initial particle count rate in order to effectively “tune” the final dilution of sample sheath flow to the particle concentration of the sample. A sheath fluid syringe pump and a test sample syringe pump are driven by motors which are adjusted by a data analyzer. The data analyzer compares a particle count rate measured by a detection assembly to a predetermined reference value and determines if the count rate is too high or to low. Accordingly, one of several pump profiles is initiated to adjust the flow rate of the sheath fluid or test sample or both. Advantageously, the low cell count precision is improved and the upper limit cell count is expanded.
