    Abstract: A circuit assembly includes a printed circuit board which has a plurality of copper traces formed thereon. Heat generating electronic components are surface mounted on the board in contact with parts of the traces. A heat conducting copper plate is mounted on the board adjacent to and spaced apart from the electronic components, and in contact with other parts of the traces. A silicon pad is mounted on the plate, and a heat sink member is mounted on the pad so that the pad is between the heat sink member and the traces. Heat conducting solder bridges are formed between the edges of the electronic components and the edges of the plate.

    Abstract: A camera holder, comprising a mast having a proximal end and a distal end, for supporting a camera having a shutter near the distal end. A camera mounting head is located near the distal end, having an upper plate and a lower plate for mounting the camera therebetween. The camera mounting head is attached to the mast with an arm. The arm is adjustable to vary the relative angle of the mast and camera mounting head, and relative distance therebetween. The mast may vary in length by adding additional tubular mast sections. An actuator assembly is located on the upper plate, having a plunger for engaging the shutter of the camera, an actuating lever pivotable on a fulcrum, and wherein an actuation cable is attached to the actuating lever on an opposite side of the fulcrum from the actuating plunger. The actuation cable extends from the proximal end toward the distal end for allowing remote operation of the camera when a user holds the camera holder at the proximal end.
