  • Patent number: 6501659
    Abstract: A system and method for identifying a match between an industrial PC to a slot in a rack which uses a blind mating keying and locking plates, so that when the mechanical keying plate and locking plate do match, then full insertion of the PC into the slot is permitted. When a mis-match occurs, then full insertion is prohibited.

  • Patent number: 6473709
    Abstract: A computer having a backplane and a motherboard disposed on the backplane along with expansion slots for receiving expansion cards. The backplane further having circuitry coupled thereto for performing an alarm function where the alarm circuitry is not coupled to a card occupying one of the expansion slots, instead the alarm circuitry is coupled to the backplane in a manner so that it is not directly under the supervision of the system processor on the motherboard. The alarm circuitry including processors which use the LON bus protocols for receiving and transmitting information relating to environmental conditions in the PC.
