An EMI shield, or module cage, mounts to a circuit board such that a first portion of the module cage extends above a first planar surface of the circuit board and a second portion of the module cage extends below a second planar surface of the circuit board. The module cage surrounds a corresponding transceiver module and allows airflow to travel across the transceiver module and through the module cage in a direction substantially perpendicular to a planar surface of the circuit board to cool the transceiver module. In one arrangement, multiple module cages attach to the circuit board in a modular configuration. Such a configuration allows attachment, to the circuit board, of the number of module cages corresponding to the number of transceiver modules required or utilized by the circuit board.

Methods and apparatus for mounting an electromagnetic interference shielding cage to a circuit board

A gasket comprises an edge, a first end and a second end bounding the edge, and a plurality of slits spaced between the first and second ends. At least some of the slits are at one or more oblique angles to the edge. Therefore, a reduced risk of snagging is present when mating one gasket with another with a sliding motion. A method for installing a first electronic device adjacent to a second electronic device comprises coupling a first gasket to the first electronic device and coupling a second gasket to the second electronic device. The first device is placed near the second device such that the first and second gaskets contact with a sliding motion. When in contact, the slits of the first gasket are not parallel with the slits of the second gasket.

A portable data collection system employing a portable data terminal having increased functionality is disclosed. The portable data terminal includes an integral magnetic stripe reader for reading information magnetically encoded on a magnetic stripe card, such as a credit card or the like. An interchangeable feature pod may be attachable to the data terminal and may include a selected data collection or communication device such as, for example, a data communication port, optical indicia reader or laser scanner to facilitate data entry and communication. The interchangeable feature pod may include a compact, ergonomically efficient actuator for activating the selected data collection or communication device. Interconnection of the portable data terminal to interchangeable feature apparatus such as an electrical power supply, peripheral devices, or data communication apparatus may be accomplished via separate line connection, a port replication apparatus or a vehicle docking apparatus.

Portable data collection

A circuit board assembly has (i) a circuit board including a section of circuit board material and a circuit board component mounted to the section of circuit board material, (ii) a support assembly that supports the circuit board, and (iii) a heatsink that cools the circuit board component mounted to the circuit board. The heatsink includes a receptacle that fastens to the support assembly, and an adjustable member that engages with the receptacle. The adjustable member is movable relative to the receptacle in order to control a distance between the adjustable member and the circuit board component. The adjustable member can be positioned properly (e.g., with the correct pressure) for proper heat transfer therethrough. Moreover, circuit board assembly can include multiple heatsinks for cooling multiple circuit board components with the adjustable member of each heatsink being individually adjusted to accommodate any tolerance differences between the circuit board components.
