Abstract: A tire monitoring system including a monitoring module for mounting on a wheel. The monitoring module having a transmitter configured to wirelessly communicate with a mobile device of a user, a pneumatic sensor receiver communicatively coupled with the transmitter, a temperature sensor communicatively coupled with the transmitter, and a vibration sensor communicatively coupled with the transmitter.

Abstract: Apparatus and methods for transporting a marine outboard engine include securing a marine outboard engine to an engine support cart having a pair of rear wheels and a pair of front wheels, wheeling the engine support cart into a cage assembly, and mounting a removable dolly assembly to the cage assembly. The dolly assembly includes a floor-engaging wheel. The marine outboard engine transportation apparatus with the marine outboard engine secured within is balanced on the pair of rear wheels and the floor-engaging wheel when the cage assembly is tilted backwards.

Abstract: A magnet is fixed to an output shaft of a motor. The output shaft is rotated such that a magnetic field emitted by the magnet also rotates. A voltage pulse is generated from a passive sensor when the magnetic field rotates past the passive sensor. The voltage pulse is generated using a Wiegand wire. An active sensor is activated, from an unpowered state, in response to the voltage pulse. The active sensor detects a position of the magnet that correlates to a position of the output shaft.

Abstract: A pump jet apparatus for a motor includes an annular exhaust channel to receive exhaust gas from the motor. At least one hollow exhaust vane extends radially from a vane hub surrounding the annular exhaust channel. The at least one hollow exhaust vane is in flow communication with the annular exhaust channel to discharge the exhaust gas received from the motor through an exhaust discharge outlet. An impeller driven by the motor is mounted rearward of the annular exhaust channel and the at least one hollow exhaust vane and exhaust outlet.

Abstract: Apparatus and methods for mounting an outboard motor to a transom of a boat include a transom mounting plate having a marking disposed a centerline of the transom plate and an indentation centered at the centerline for receiving clamping members of an outboard motor.

Abstract: Apparatus and methods for raising a retractable mast comprise engaging at least three flat flexible strips such that each strip forms a side of a mast. Each strip comprises a set of tabs and slots disposed along opposite edges of the strips. The housing may further comprise a feed mechanism operable to interlock the at least three lengths of flexible strips by drawing the strips together causing each tab of each strip to engage with a slot of an adjacent flexible strip. In addition, the apparatus may comprise a controller module operable to control extending and retracting the mast. The apparatus may be incorporated in a robotic device operable to travel in at least a horizontal plane and extend the retractable mast.
