Abstract: A padded seating cushion having a main section at the front end and a pair of arms extending rearwardly therefrom to define a generally U-shaped aperture open and extending to the rear of the cushion to support the user's ischial portions while alleviating direct pressure on the coccyx. The arms define an inner section having inner side walls defining a thermal transfer chamber in which a thermal transfer unit is placed to selectively provide heat or cold for the user. The thermal transfer unit attaches to a lower chamber member that attaches to the arms. The thermal transfer unit comprises a thermal unit disposed in a thermal container, preferably in the form of a pouch. The cushion attaches to a seat with removably attached straps connected to ring members on each side of the cushion, providing a padded surface that does not shift with the movements of the user.

Abstract: A circuit board with vias that are suitable for use as test pads can be made according to a method whereby a first end of a via is blocked prior to heating solder paste that covers the opposite end of the via. As a result, air is trapped in the via when the solder paste is heated, which prevents melted solder paste from flowing in. Instead, the solder paste forms a dome shaped test pad over the via, which facilitates contact with the test probe. When applied to OSP circuit boards, the result is an OSP board with at least via that has a blocking material at one end and a solder dome over the opposite end.
