Abstract: A paddle assistance and propulsion system for use with personal watercraft is disclosed. The paddle assistance and propulsion system may include different mounting techniques that allow a propulsion device (e.g., a motor) to be coupled to various types of personal watercraft. Some mounting techniques may include the use of magnets to couple a motor-side mount to a boat-side mount. The paddle assistance and propulsion system may also utilize a variety of sensors in combination with control systems to provide various types of paddle assistance and different types of paddle assistance modes for the user of the personal watercraft.

Abstract: A fluid retainer cartridge assembly is disclosed. The fluid retainer cartridge assembly includes a base portion and a cap portion. The base portion defines a plurality of implement-receiving channels. The cap portion is removably-connected to the base portion. The cap portion defines a fluid-receiving void that is fluidly-divided into an upstream fluid-receiving void and a downstream fluid-receiving void by a flange of the base portion that is disposed within the fluid-receiving void of the cap portion. The upstream fluid-receiving void is in fluid communication with the downstream fluid-receiving void by a fluid-flow passage formed by the flange of the base portion. A method is also disclosed.

Abstract: An optical analysis system is disclosed. The optical analysis system includes a wireless optical device. The wireless optical device includes a body with a port that receives a test strip. A sensor array may be positioned within the body that aligns with at least part of the test strip. The sensor array may include a plurality of individually addressable sensors and at least one illumination element associated with each sensor. The at least one illumination element may illuminate a discrete portion of the test strip that is aligned with the individually addressable sensor associated with the at least one illumination element. The sensors may independently assess reflected illumination signals from the discrete portions of the test strip aligned with the individually addressable sensors.
