Disclosed herein is a portable table having numerous favorable characteristics. The table comprises a tabletop, a column connection, and a column. The tabletop includes a core, a thickness, a perimeter section, and a bottom surface. The column connection is positioned within the thickness of the core and within the tabletop, and includes a flange and a cylindrical sleeve having a first fastener. The column includes an insertion end that includes a second fastener shaped to removably engage the first fastener and secure the column to the column connection. The insertion end is shaped to removably fit within the cylindrical sleeve of the column connection.

A powertrain includes an Atkinson cycle engine having at least one cylinder, a crankshaft, and an air intake system that provides selective fluid communication between the at least one cylinder and the atmosphere. A motor is in hybrid combination with the engine, and a compressor is configured to selectively pressurize air in the air intake system. The powertrain provides the fuel efficiency of an Atkinson cycle engine while compensating for the reduced torque output of an Atkinson cycle engine.

Disclosed herein is a portable panel having numerous favorable characteristics. The panel comprises a core having a length, a width, a first side and a second side. A first fiber layer is attached to the first side while a second fiber layer is attached to the second side. A first polyurethane layer is impregnated in the first fiber layer while a second polyurethane layer is impregnated into the second fiber layer. A first skin is attached to the first polyurethane layer while a second skin is attached to the second polyurethane layer. The panel can be used in the manufacture of tables, flooring, risers, stages, bleachers, and the like.

A lightweight, portable table comprising a unitized table top member and legs secured to the table top member. The unitized table top member includes table top and bottom elements and a rigid support member. A hardened foam body is joined to the top and bottom table elements and is formed around the support member in sufficient volume to support the support member within the table top member. A lightweight core element is positioned within the table top member joined to the hardened foam body. The table advantageously requires few parts and is economical to manufacture yet is sturdy and easily transported.

Data collection and analysis processes include collecting energy consumption data from an in-vehicle energy source sensor, collecting emissions data from an in-vehicle emissions sensor, the emissions data reflecting emissions produced by a vehicle, and collecting mileage data from a mileage sensor in the vehicle. The data collection and analysis processes also include processing the energy consumption data and the emissions data as a function of the mileage data, calculating an efficiency rating from the processing, and transmitting results of the processing to a data collection system.
摘要:
A semi-autonomous vehicle couplable to a parent vehicle is described, and includes a chassis supported on first and second axles coupled to a plurality of wheels, a propulsion system configured to transfer torque to one of the wheels, a steering system configured to control direction of travel of the semi-autonomous vehicle, a braking system configured to apply braking force to the wheels, a high-voltage electrical energy storage system, an extra-vehicle communications system, and an extra-vehicle sensory system. A control system operatively couples to the propulsion system, the steering system, and the braking system. A coupling device is configured to electrically couple the semi-autonomous vehicle to the parent vehicle, the coupling device consisting essentially of a high-voltage DC electrical power bus electrically coupled to the high-voltage electrical energy storage system.
