Abstract: Articles for supporting a computer on a user's lap, for cooling the computer, and for isolating the user from heat from the computer. Different embodiments may include a top surface for contacting the computer, a bottom surface for contacting the user's lap, a hollow area, a top aperture through the top surface to the hollow area, a fan, or a combination thereof. The top surface may be at an acute angle to the bottom surface, the fan may include an electric motor powered through a USB cable, or both, as examples. Various embodiments may include at least one side opening or rear opening to the hollow area to allow air to circulate, a foam portion, fabric covering the foam, a plastic portion which provides increased stiffness, or a combination thereof.

Abstract: Articles for supporting computers on users' laps and for isolating the users from heat from the computers. Embodiments may include a body, a top surface for contacting the computer, a bottom surface for contacting the user's lap, and back and front walls or surfaces. In various embodiments, the body defines a hollow area and a side opening, the back is taller than the front, the top surface is at an acute angle to the bottom surface, the bottom surface has a greater horizontal dimension from front to back than the top surface, the bottom surface has a greater horizontal dimension from left to right than the top surface; the article has a cross section that is a trapezoid (e.g., isosceles), the article comprises a foam portion (e.g., tubular) and fabric covering the foam portion, or a combination thereof. In some embodiments, each surface comprises the foam covered with fabric.

Abstract: An article for supporting a computer on a user's lap that cools the computer and isolates the user from heat, and methods of manufacture. Some embodiments include a body, a top surface, a bottom surface, a hollow area in between, an aperture through the top surface to the hollow area, and either a fan to move air through the aperture or an indentation in the top surface to allow air to circulate by the computer. Embodiments include a foam portion, a plastic portion that provides stiffness, a fabric covering and one or more side or rear openings to allow airflow. The fan may be powered from a USB port on the computer.

Abstract: Assembly of handsets is accomplished without the use of mechanical fastenings. Energy directors are provided at the peripheral edges of one of the two housings forming a handset, and the two housings are united by sonic welding. Severe damage can be caused to transducers mounted in the handset by sonic welding, but the use of energy directors directs the sonic energy around the transducers, avoiding damage. The transducers can be held in place by heatstaking positioning members. A rigid assembly which is readily amenable to automated assembly is provided.
