  • Patent number: 7315951
    Abstract: A high speed non-volatile electronic memory configuration and method is disclosed. In one particular exemplary embodiment, the high speed non-volatile electronic memory configuration may be realized comprising a high speed volatile memory, a non-volatile memory coupled to the high speed volatile memory, a controller coupled to the high speed volatile memory and the non-volatile memory, and a power level detector that detects when power is above a particular minimum operating voltage level. The controller monitors data storage changes made within the high speed volatile memory and controls the transfer of stored data from the high speed volatile memory to the non-volatile memory, and vice-versa, when power is above the particular minimum operating voltage level.
    Type: Grant

  • Patent number: 7058175
    Abstract: An auxiliary connection mechanism for allowing a Digital Switching System (DSS) to share an analog line with an analog device (via an auxiliary device port) is disclosed. The auxiliary connection mechanism includes a pair of relays for releasably connecting the auxiliary device port and the DSS to the analog line. When the analog line is idle, both the analog device and the DSS are connected to the line in order to receive incoming calls on the analog line. However, once one of the devices (either the analog device or the DSS) uses the line, the other device should not access the line. A busy line detect circuit is included to detect whether a device is using the line.
