Active container
A multi-functional active container (e.g., luggage or suitcase) with a plurality of sensors and actuators is described. The container may include a body defining an enclosure and having at least one opening. The container may include a processor, a wireless receiver, and an electronically controllable lock. The processor can selectively lock or unlock the electronically controllable lock based on signals received via a wireless receiver (e.g., via Wi-Fi or BLUETOOTH connections). In some examples, a distance between the active container and a remote device (e.g., a smart phone) can be determined (e.g., based on relative GPS signals or connection strength) and if the distance exceeds a threshold, the electronically controllable lock can be activated to secure the container. Further, the container may include a rechargeable power source for powering external devices and an integrated weight sensor for detecting the weight of the container.

InactiveUS6325463B1Simple and inexpensivePrevent travelHubsWheel protectionAtmospheric airEngineering
A vent system for a wheel hub comprising a first filtered vent at the wheel end cavity and a second vent formed by a one-way, pressure relief valve venting the axle tube to atmosphere. The vent system defines a vent path from the wheel end cavity through a first, preferably filtered, vent into the axle tube then through a second check valve connecting the axle tube to atmosphere. A porous material is positioned to cover the vent passage at the wheel end cavity for allowing a flow of gases to enter and exit the vent passage while preventing liquids and other contaminants from traveling therethrough. The porous material is held in place over the vent by a snap ring or other suitable retention system disposed within the vented plug member. The second axle tube vent is disposed along the axle tube to vent the tube itself to atmosphere with pressure relief

Systems and methods for preloading a bearing and aligning a lock nut
A method of adjusting preload on a bearing assembly of a wheel mounted on an axle or spindle with a lock nut includes mounting a preload adjustment tool onto a threaded axle or spindle. The load on the bearing assembly is increased using the tool. The wheel on the axle or spindle is rotated to set the bearing assembly. The load on the bearing assembly is decreased to a desired maximum preload on the bearing. After decreasing the load on the bearing assembly to a desired maximum preload, the lock nut is tightened by hand until the lock nut cannot be further tightened. The lock nut is loosened by rotating the lock nut to a preferred location where a guide mark on the tool aligns with one mark on the lock nut located closest to the guide mark wherein a resultant preload on the bearing assembly is within a preset range from the desired maximum preload.
