Pluggable Storage Modules

Pluggable storage modules having their own power supply function as storage media for portable data recorders, minicomputers and like devices. The pluggable storage modules are used in the same manner as other storage media such as magnetic tapes, cards and disks.

Solid-state storage element 10, Figs. 1 and 2, is mounted on circuit board 11 together with energy storage capacitors 12, Fig. 1, or batteries 13, Fig. 2. The energy storage capacitors 12 or batteries 13 maintain data in the storage elements 10 when the pluggable unit is transferred from a storage retainer 20, Fig. 3, or when the utilizing device such as portable data recorder 30 switches into a low-power mode. A light-emitting diode 15, Fig. 1, functions as a power indicator and when on, indicates that voltage is available to the storage modules
10.

Storage retainer 20 contains a fail-safe power system to assure that power is being applied to the storage modules. Additionally, storage retainer 20 can function as a modem.

The portable data recorder 30 of Fig. 3 includes low-power switch 35, as in Fig. 4. This switch can be manually operated or it can be operated in response to a logic condition, whereby power is maintained on storage module 10 but not on the control circuitry 40. When control switch 45 is closed, switch 35 is transferred to the upper contact and main battery 50 provides power to both storage module 10 and control circuitry 40.
