A protective cover for a dual inline memory module (DIMM) circuit card includes a pair of cover members for substantially containing the DIMM circuit card. The cover members are secured to opposite sides of the DIMM circuit card. The pair of cover members defines a socket-receiving channel between respective printed-circuit-board (PCB) mating faces of the cover members. The cover members includes a plurality of positioning features engaging the DIMM circuit card for positioning a portion of the DIMM circuit card within the socket-receiving channel.

Protective cover for DIMM circuit card

In many technical applications, situations often arise where it is desirable to know, in real time, if a circuit is functioning. That is, it is desirable to know if, for example, a heater element is operational or blown (open). By sensing the current flowing to the circuit, it is easy to determine if the circuit is operational. However, this only provides information while the circuit is in the process of operating. There must be some real-time connection with the request or demand for power to know if in fact the device is non-operational, or if there is simply no controller request for power. A system (and method) according to the invention includes a real-time, simultaneous current and voltage sensing and arbitration device which provides a single, point of use implementation, and allows for detection and signaling of a fault condition. A circuit breaker may be constructed to incorporate such a system.

Automation of stacking of lamina included in a modular circuit package is provided by use of a plurality of heads carried on a preferably rotating head transport assembly. The head transport assembly is movable between two locations in which heads simultaneously brought to respective supply, alignment and disposal stations alternately pick up or deposit lamina, plates, separator sheets or protective sheets, respectively. Each lamina, sheet or plate deposited at the alignment station is pressed down over elongated alignment pins while maintaining only a short protrusion of the alignment pins above the existing stack. Continuous production is provided by carousels which bring alignment fixtures to the alignment station and magazines containing lamina to the supply station. Selection among lamina is provided by an elevator assembly which moves a magazine to a location at which a desired lamina can be selected therefrom, preferably under computerized control. The capacities of the alignment fixtures, magazines, carousels and supply stations support production of a plurality of stacks of lamina on an alignment fixture and continuous production of a plurality of production runs without resupplying the apparatus with lamina or plates.
