Abstract: A modular securement device may include a receiver coupler configured to be removably coupled to a vehicle hitch. A mounting plate may be coupled to the receiver coupler. A first slot may extend longitudinally along a top surface of the mounting plate, and a second slot may also extend longitudinally along the top surface of the mounting plate and may be spaced apart from the first slot. An optional support base may be moveably coupled to the mounting plate via engagement with the first or second slot. A crank receiver may be coupled to the support base. A lateral support may also be coupled to the support base, and a wheel support may be coupled to the lateral support.

Abstract: Imaging systems and techniques are described. In some examples, an imaging system receives an image captured by an image sensor. The imaging system determines that an image region in the image includes a depiction of an object of a specified category. The imaging system adjusts a hue (and/or saturation and/or brightness) of at least one pixel of the depiction of the object in the image region to a specified hue (and/or saturation and/or brightness) to generate a processed image.

Abstract: Embodiments of the present invention comprise a bicycle trailer hitch for use in securing a bicycle trailer to a bicycle. Unlike prior art trailer hitches the transfer of most of the load between an associated bicycle and an associated bicycle during use does not pass through the bolt/fastener used to couple the bicycle attachment section to the trailer attachment section thereof. Rather, the majority of the load is transferred through a direct connection between the respective sections.

Abstract: An apparatus and method of determining the gas generation potential of a liquid capable of producing gases. The apparatus may be characterized as a cylinder having first and second openings, capable of holding a volume of liquid capable of generating gas; plugging means attached to the second opening of the cylinder for sealing the second opening; a multi-port connector having at least first, second, third and fourth ports, wherein the first port is attached to the first opening of the cylinder; pressure reading means attached to the second port of the connector; valve means attached to the third port of the connector, the valve means suitable for opening and closing to allow liquid and gases to enter and exit the cylinder; and pressure relief means attached to the fourth port of the connector, wherein the fourth port is closed during the measuring operation.
