Abstract: An adaptive exercise system includes a treadmill, at least one imaging device, and computing hardware configured to determine an exertion level of a user, and modify one or more treadmill setting based on the exertion level. The system may be configured to derive user exertion level from infrared imaging captured by the at least one imaging device. In some embodiments, the system may identify appropriate modifications to the treadmill based on the user’s current exertion levels and baseline levels.

Abstract: The integration of exercise and gaming is a growing trend, as evidenced by the popularity of interactive and virtual reality games that encourage physical activity. Existing systems often confine the user to a specific location or type of exercise equipment or user device and fail to extend the interactive experience to other environments in a cohesive manner. Various aspects of the present disclosure provide a gaming environment in which a user can experience different aspects of the environment based on the context via which the user is accessing the environment. The system may, for example, uniquely adapts game play to the context of the user's activity level and environment to enhance engagement and promote physical health without distracting from the primary activity or creating unsafe conditions for the user. Other embodiments may provide integration with physical exercise hardware to substantially eliminate spoofing and other cheating that plague some mobile games.

Abstract: A seat removal tool is disclosed for removing valve seats. A seat removal tool having a main rod, actuator rod within the main rod that actuates to cause radially expandable extraction segments to transition between an expanded position and a contracted position. When using the seat removal tool to remove a valve seat, portions of the radially expandable extraction segments may pass through a seat while the valve seat removal tool is in a contracted position. Thereafter, the seat removal tool may transition from the contracted position to an extended position, which grabs the seat. While in the expanded position, the seat removal tool may pull the valve seat from the passage.
