Abstract: A method and test apparatus determines a volume of a droplet of liquid. The test apparatus deposits a drop of liquid to be measured on a surface that provides a known contact angle with the liquid under the deposition conditions used, thereby establishing one of: (i) an advancing, (ii) a receding, and (iii) an intermediate contact angle. The test apparatus images the drop. The test apparatus measures a dimension of height or diameter of the drop. In one embodiment, the test apparatus calculates a volume of the drop of liquid from the relationship of the contact angle to one or more parameters selected from the maximum height, the diameter of the contact patch, the radius of curvature, or the cross sectional area of the drop.

Abstract: Vessel transfer systems are provide herein. The systems include bogies, including a pivoting bogie and a rack and pinion bogie, as well as associated cradles, carriages, and power and control units. The pivoting bogie includes a first side frame, a second side frame, at least one wheel coupled with each of the first and second side frames, and a lift member coupled with each of the first and second side frames. The lift member is pivotably coupled to the first side frame. The rack and pinion bogie includes a frame and pinion gears coupled with the frame. The pinion gears can be selectively coupled with a gear rack, such as at a shipyard. Also provided herein are methods of use of one or both of the bogies and associated equipment, such as for moving vessels within a shipyard.

Abstract: Method and apparatus are disclosed for biometric authentication for a vehicle without prior registration. An example vehicle include a biometric scanner to generate a biometric token and a body control module. The body control module when the biometric token is authorized, enable san ignition switch. Additionally, when the biometric token is not authorized and an additional source of authorization is received, the body control module (a) tracks usage of the vehicle subsequent to receiving the biometric token, and (b) marks the biometric token as authorized when the usage satisfies a threshold.

Abstract: A chain wheel designed to haul in, pay out and/or guide a mooring chain that includes multiple chain sizes. In one configuration, the chain wheel is a dual chain wheel that includes pockets sized to support a larger chain size and pockets sized to support a smaller chain size. The pockets include flat surfaces that support links of the chain as it passes over the chain wheel. The chain wheel also includes whelps designed to support and guide chain segments into proper alignment with the chain wheel.
