摘要： A collapsible spider wheel assembly on a towing device enables storage of the device into a standard rectangular space. Once collapsed, the collapsible spider assembly is protected within the body of the towing device. Furthermore, actuation of the folding and unfolding may be accomplished through the usual telescoping of the carrying handle of such a device, such as in a suitcase embodiment. While the spider wheels are in the open position, the carrying apparatus may exert a drive force to climb up stairs and braking force to descend stairs. The unit operates as a normal wheeled carrying apparatus while traversing a horizontal surface.

摘要： An vehicle rooftop cooling system includes a radiator located outside of the engine compartment of a vehicle, the radiator having a liquid coolant inside the radiator; a fan coupled to the radiator and configured to extract hot air from the radiator; a first sensor proximate to the radiator configured to measure coolant temperature of the coolant in the radiator; and a controller communicably coupled to the first sensor, the controller configured to receive inputs from the first sensor, to make determinations based on the received inputs, and to communicate control signals across a controller area network (CAN) in response to said determinations, wherein the controller is further configured to communicate a first control signal to cool the liquid coolant upon determining that the first sensor has measured temperature above a threshold.
