A drawer slide which is capable of moving in and out of the housing of a computer or other electronic apparatus is configured to receive an interface card which is connected into the circuitry of the computer when the drawer slide is in a fully inserted position. The drawer slide rides in a drawer guide which is secured to the computer structure. An interface connector is mounted on the drawer guide and engages a connector on the interface card for connecting the interface card to the remainder of the computer circuitry. A key lock mechanism prevents unauthorized movement of the drawer slide and the associated interface card out of the computer housing.

A heat sink for electronic devices which are surface mounted on a printed circuit board includes two side members, a connecting bridge, a foot on each side member which is soldered to a mounting pad on the printed circuit board, a locating element on each side member which engages an aperture in the printed circuit board during assembly, and a group of heat dissipating fingers on each side member. The heat sink can be placed over an electronic device which is surface mounted to the mounting pad on the printed circuit board and the feet of the heat sink can be soldered to the mounting pad simultaneously with the soldering of the electronic device to the mounting pad on the printed circuit board.

An apparatus which is a single portable device for scanning and downloading data. The apparatus employs a laser within an optical scanner to accomplish both scanning and downloading functions. In addition to the optical scanner, the apparatus employs control and communication circuitry for switching from scanning to downloading and for modulating an outgoing laser beam during downloading. A modulating material, such as a liquid crystal display or electrochromic lens, is excited to modulate the outgoing laser beam passing through it. The optical scanner also includes a motor-driven mirrored spinner which may be stopped to accomplish a high rate of data transfer during downloading using a highly directional beam.

An apparatus for controlling the charging voltage applied to a battery cell includes a printed circuit board having a flexible portion comprising a heat sensitive material which is wrapped around the battery cell for sensing the temperature of the battery cell during charging of the battery cell. Circuit means connected to said temperature battery apparatus disables the charging voltage upon the temperature of the battery cell reaching a predetermined level and generates a trickle charge in response to the disabling of the charging voltage.
