Abstract: A skate (e.g., an ice skate) for a user (e.g., a hockey player). The skate comprises a skate boot for receiving a foot of the user and a skating device (e.g., a blade and a blade holder) disposed beneath the skate boot to engage a skating surface. The skate boot may be designed to better fit the user's foot and/or enhance skating performance of the user, such as by being shaped in accordance with anatomy of toes of the user's foot and/or enhancing integrity of the skate boot.

Abstract: A system is provided in which a user interacts with other users by liking and matching with them. Each time a user likes or matches with another user, they must rank that user in relation to the other users they have already liked or matched with. Each user's rank is unique and signifies the level of priority that the other user feels towards them. The rank given is displayed to the other user. Users continually adjust the ranking of others user as they use the system, ranking other users a higher or lower priority as they like and match with more other users and change their priority of the people they want to communicate with. According to one implementation, after rankings have been established in this manner, the system only allows users to have a select number of open messages with other users at any one time, to reduce the negative effects of too many messages such as ghosting or poor communication.

Abstract: A cryogenic nitrogen sourced gas-driven pneumatic device that is configured to provide a pressurized gas to end devices is described herein. In some instances, the a cryogenic nitrogen sourced gas-driven pneumatic device may include a cryogenic storage tank that stores liquid nitrogen under pressure, a pressure build circuit configured to build and hold pressure in the cryogenic storage tank, an economizer circuit configured to draw gas that forms in the cryogenic storage tank for an end device, and a vaporizer is configured to convert the liquid nitrogen into a gas as it is drawn through the vaporizer.

Abstract: A method of applying wax to the top surface of a surfboard. The method may include heating the wax until the wax is molten and in liquid form. Then the liquid wax may be applied to the surface. The liquid wax may then cool and harden on the top surface of the surfboard. In certain embodiments, designs, ripples and patterns may be formed on the liquid wax when the liquid wax is on the surfboard.
