Abstract: An electrical circuit pack ejector system provides a preemptive warning to the circuit pack that allows redirection and disabling of circuit pack functionality prior to ejection and subsequent disconnection of power and input/output signal contacts. The ejector system is based on proximity detection that measures the distance between a Hall-effect sensor and a magnet affixed to an ejector arm. The magnetic field strength increases as the magnet approaches the sensor. Once the sensor threshold is reached, a logical bit from the sensor is flipped and a positive ejector engagement is surmised. As the ejector arm rotates away from the sensor, the magnetic field strength around the sensor is reduced. Once the sensor threshold is reached, a logical bit from the sensor is flipped and a negative ejector engagement is surmised. The circuit pack then redirects and disables functions prior to the power and signal connectors physical disengagement.

Abstract: The present invention is related to a Compact Peripheral Component Interconnect (cPCI) front panel assembly that is adapted to keep its corresponding cPCI front card's printed circuit board from bending. The cPCI front panel assembly should make its corresponding printed circuit board stronger to prevent circuit board damage and to maintain the cPCI front card envelope standard even before the card is inserted into the card slot.

There is a fixing member on the base plate of the casing of a computer processor where the motherboard is installed. When the motherboard is mounted onto the base plate at a selected location, the notch of the clip stem straddles the fixing member.
