Abstract: The present invention extends to wagons with a bathroom module and standalone bathroom modules. A bathroom module includes a water heater connected to a sink, a shower, and a toilet. The bathroom module further includes a protective layer on the exterior and an exhaust fan to facilitate the management of moisture that may build up within the bathroom module. The bathroom module can be connected to various systems provided by a wagon, such as water, gas, electrical, A/C, heat, and sewer systems connected to external sources. Alternatively, the bathroom module can standalone and include its own water, gas, electrical, A/C, heat, and sewer systems connected to external sources. Thus, when paired with a companion wagon, the bathroom module may be installed or removed as desired.

Abstract: The present invention pertains to systems and methods of individual power output measurement. One embodiment relates to a pressure sensing device configured to be mounted on the bottom surface of a shoe. The device includes a sensor, a wireless communication system, a housing, and a mounting system. A second embodiment relates to a direct power measurement system including a pressure sensing device, a computer module, and a display module. In a bicycling application of the system, the device is mounted on the bottom surface of a shoe so as to measure applied pressure between at least one of the rider's shoe and corresponding bicycle pedal. The computing module mathematically converts the measured pressure as a function of time to a value of power exerted by the rider. In addition, the computing module may utilize the measured pressure as a function of time to compute the rider's cadence (pedal revolutions per unit of time).
