A control system for a vehicle comprises a power source, a power transmission link, a plurality of input and output devices, a plurality of microprocessor-based interface modules, and a communication network that interconnects the interface modules. The interface modules are also each coupled to respective local subsets of the input and output devices. Each of the interface modules collects input status information from the respective local subset of the input devices and transmits the input status information over the communication network to the remaining interface modules.

A power distribution and control system for a military vehicle comprises a power source, a power transmission link, a plurality of input and output devices, a plurality of microprocessor-based interface modules, and a communication network that interconnects the interface modules. The interface modules are also each coupled to respective local subsets of the input and output devices so as to permit distributed data collection from the input devices and distributed power distribution to the output devices. Each of the interface modules collects input status information from the respective local subset of the input devices and broadcasts the input status information over the communication network to each of the remaining ones of the interface modules. Each of the remaining ones of the interface modules receive the input status information and locally store the input status information.

A wheel assembly for a small-scale machine includes a pair of opposing, individually-driven wheels, associated motors and possibly one or more gear assemblies. The motors receive separate drive signals from a control electronics subsystem of the wheel assembly. The motors can be connected to the wheels via the gear assemblies. Because the wheels are separately driven, driving the two wheel assemblies at similar or different speeds drives the wheel assembly over straight or curved paths. An orientation assembly allows the orientation of the wheels to the machine to be controllably altered. A height adjusting assembly allows the distance between the wheels and a point on the machine where the wheel assembly is attached to be adjusted. The rotational axis that the wheel assembly rotates about when re-oriented need not pass through either wheel of the wheel assembly. The wheels can be driven by control signals generated by on-board control electronics.

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.

When the drive of a lubricant pump (46) is stopped to prevent the lubricant pump (46) from assuming an idling state, a determination is made as to whether or not a temperature difference (ΔT) between the temperature (T) of a lubricant oil detected earlier by a temperature sensor (51) and a warning temperature (Toh) is equal to or lower than a predetermined threshold value (α). When the temperature difference (ΔT) is within the threshold value (α), an “overheat” warning is issued to an operator of a dump truck (1). In consequence, even in a case where a temperature sensor (51) is provided on the output side of the lubricant pump (46) by being located on an outer side of a wheel mounting case (19), planetary gear reduction mechanisms (23), (31) inside the wheel mounting case (19) can be prevented from overheating by warning the operator of the vehicle.

In case a temperature (T) of a lubricant oil (G) cannot be detected by an oil temperature sensor (51) provided on an output side of a lubricant pump (46), the temperature (Tm) of a wheel drive motor (17) is detected by using a motor temperature sensor (53) provided on the wheel drive motor (17). By estimating the temperature (T) of the lubricant oil (G) from the temperature (Tm) of the wheel drive motor (17), monitoring is carried out as to whether or not the temperature (Tm) has risen to a predetermined temperature (Tms) at which the cooling of the lubricant oil (G) by forced circulation is deemed necessary. The drive of a lubricant pump (46) by a pump drive motor (47) is stopped until the motor temperature (Tm) rises to a level exceeding the predetermined temperature (Tms).

An all terrain adapter for a wheelchair that removably clamps onto the foot support of the wheelchair and supports a relatively large diameter, slightly inclined swivelling nose gear wheel at an extended distance from the foot support to stabilize the wheelchair when it is being pushed over soft or uneven surfaces and which swivels around when the wheelchair is moved forward to lift the front wheels of the wheelchair clear of the ground.

A lubricant circulation pump (46) which is driven by an electric motor (47) is provided in the course of a circulation path (41A, 41B) for circulating lubricant oil to a wheel mounting case (19) which is rotated together with a rear wheel (7). Turning on and off the lubricant circulation pump is controlled according to rotational speed of the rear wheel. When lubricant oil in the wheel mounting case sticks on inner peripheral surfaces thereof under the influence of centrifugal force as a result of the increased vehicle speed, the electric motor is turned off to suspend operation of the lubricant circulation pump. Consequently, the lubricant circulation pump does not suck lubricant oil in the wheel mounting case through an inlet opening (42A) of an intake pipe (42), thereby preventing the lubricant circulation pump from being put in a dry idling operation.

Towing apparatus for connecting a trailer with a towing vehicle. The towing apparatus is adapted to bear part of the weight of the trailer, thus lessening the load on the towing vehicle. This is accomplished by providing a wheel assembly on the towing apparatus which is operatively connected to an adjustable main spring which supports most of the weight of the trailer which would normally bear on the hitch of the towing vehicle. Unlike conventional towing systems, wherein the trailer tongue is rigidly attached to the trailer, the towing apparatus of the present invention employs a pivotally-mounted trailer tongue which is maintained in a horizontal position by an adjustable secondary spring or springs. The use of main and secondary springs presents a relatively constant load to the trailer hitch, even when the trailer is being towed across rough or uneven surfaces.

When lubricant oil in the wheel mounting case sticks on inner peripheral surfaces thereof under the influence of centrifugal force as a result of the increased vehicle speed, the electric motor is turned off to suspend operation of the lubricant circulation pump. Consequently, the lubricant circulation pump does not suck lubricant oil in the wheel mounting case through an inlet opening (42A) of an intake pipe (42), thereby preventing the lubricant circulation pump from being put in a dry idling operation.
