Abstract: A fuel tank includes a port and an open-cell foam. The open-cell foam is configured to retain a liquid fuel by an interfacial surface tension between the open-cell foam and the liquid fuel. The open-cell foam is configured to selectively release the liquid fuel when a surfactant is applied to the open-cell foam to reduce the interfacial surface tension between the open-cell foam and the liquid fuel.

Abstract: Systems, methods, and apparatuses for displaying items based on time data, such as time of entry, include use of a display device configured to display items, and a processing circuit configured to control operation of the display device and modify characteristics associated with the items. An input, such as a touch, may be used to guide display of the items, including presenting the items in a replay format.

Abstract: A helmet testing apparatus including a movable member, a sensor coupled to the movable member and configured to acquire compliance data regarding a liner disposed within a shell of a helmet through engagement of the sensor with the liner, and a processing circuit configured to determine a rating for the helmet based on the compliance data and predetermined compliance parameters for the helmet.

Abstract: Embodiments disclosed herein relate to a garment system including at least one sensor and at least one actuator that operates responsive to sensing feedback from the at least one sensor to cause a flexible compression garment to selectively constrict or selectively dilate, thereby compressing or relieving compression against at least one body part of a subject. Such selective constriction or dilation can improve muscle functioning or joint functioning during use of motion-conducive equipment, such as an exercise bike or rowing machine.
