Abstract: An apparatus for automatically adjusting tension on retention member to hold multiple objects together. Examples include using retention apparatus to obtain optimal fit and use of a human wearable item such as article of footwear. Sensors may be used to sense changes in movement of the article of footwear, of the person wearing it, or of a third object such as a vehicle carrying the person. A retention member may surround at least a portion of the objects, and an actuator may be included that automatically rotates a rotating member such as a gear or pulley that may be coupled to the retention member. The rotating member may be configured to automatically adjust tension on the retention member many times per second based on control signals from control logic responsive to the sensors.

Abstract: Disclosed herein is a multifunctional stand-up paddleboard (MFSUP) comprising a paddleboard, a paddle, and a drive unit. At the stem of the paddleboard is a docking port configured to receive the drive unit that propels the paddleboard. In some embodiments, the paddleboard comprises a rigid midsection, and an inflatable bow and stem. The inflatable portions are inflated during use and deflated then folded over the midsection during storage. A control paddle having control switches send command signals by Bluetooth to the drive unit to control the velocity of propellors. A battery bank is disposed on the midsection and provides power to the drive unit. A solar panel can be included on a superior surface of the paddleboard to supply power to the battery bank. The drive unit is removable from the docking port for propelling a human through a water body. Other features and methods are also disclosed.

Abstract: Closed cell chitin foam is provided. The closed-cell chitin foam composition does not absorb water, is biodegradable, and is mechanically characterized by a density range of 16 to 800 kg/m3, closed-cell pore sizes ranging from 50 microns to 1 mm, an elastic modulus of 3 to 175 MPa, and a tensile strength of 0.15 to 6.5 MPa. The chitin is at least 70% acetylated. In one aspect, the foam is enclosed in a shell e.g. in the form of a surfboard. Chitin foam according to this invention is fully biodegradable. The chitin foam overcomes the current problems with foams that contain polyurethane and polystyrene, and which are manufactured from petroleum-based sources. Petroleum based foams are not renewable, have an adverse impact on our environment, and pose significant health hazards to those who manufacture them. The chitin foam with its water-based manufacturing process and naturally sourced chitin, solves these problems.
