20140271268 | FAN SHROUD AND MOTOR ASSEMBLY COMPRISED THEREOF - This disclosure proposes designs for a fan shroud that dissipates thermal energy from a motor using a single, externally-powered fan design. Examples of the proposed fan shroud allow the cooling fluid to achieve maximum velocity at a position at which the fan shroud exposes the flow to cooler ambient air that surrounds the fan shroud/motor assembly. In this configuration, the high-velocity cooling fluid draws the cooler ambient air towards the surface of the motor, which, in turn, increases the thermal capacity of the moving cooling fluid to dissipate more thermal energy from the motor. | 2014-09-18 |

The lid is releasably locked onto the cup so as to align dipping ends of the test strips exposed through an underside of the lid with a position stabilizer, thereby causing the dipping ends to be located downwardly and submerged in fluid when the device is placed on its side in a reactive position. The position stabilizer may comprise a sidewall indentation that reduces the internal volume of the cup and keeps the cup from rolling when placed on its side. | 2014-09-18 |
