    • Fuel cell based backup unit apparatus for storage subsystems are provided. With the apparatus, at least one fuel cell is provided as part of a fuel cell power generation array that is used to provide backup power to a storage subsystem of a computing device, such as a RAM cache. A regeneration mechanism is provided for regenerating the fuel in the at least one fuel cell. A logic and control module is provided for controlling the overall operation of the backup unit including determining when to provide backup power and when to initiate regeneration of the fuel cells. A DC/DC voltage conversion module may also be provided for converting a DC output from the fuel cell power generation array into an output useable by the storage subsystem. In a hybrid embodiment, both a fuel cell power generation array and a lead-acid battery pack cache backup array may be utilized to provide backup power for a storage subsystem. In such a hybrid embodiment, the fuel cells of the fuel cell power generation array may provide backup power to the storage subsystem and/or provide a recharge voltage for recharging the lead-acid batteries in the lead-acid battery pack cache backup array.

    • A portable, hand-held data processing assembly of modular structure includes a base unit with a keyboard and a display screen. An indicia reader module is housed in a housing shell which is attachable to the base unit. The indicia reader module can contain a reflected light indicia reader for non-contact essentially instantaneous reading of bar codes of the like disposed in a spaced, non-contacting relationship to the assembly. The indicia reader module can also include a processor. The base can include a light source. Additionally, the base unit can include a battery for powering the hand-held data processing assembly. A data collection and communications module can include a stacked arrangement of a communications interface main circuit board, a radio and a laser scanner assembly which are housed in a housing shell attachable to the base unit. In this arrangement, the radio is mounted in spaced relationship to one side of the main circuit board, while the laser scanner assembly is mounted to the other side of the main circuit board. A support frame and a plurality of ground planes in the sandwiched main circuit board and a routing circuit board form an RF cage for shielding RF interference which may be generated by the radio. Also disclosed is a method for reducing the operational power consumption requirements of laser bar code scanners by analyzing reflected laser light in order to determine the presence of optically readable information sets.
