  • Patent number: 6259710
    Abstract: A system for intelligent C-plane switching in the digital enhanced cordless telecommunications (DECT) system. The present invention includes a system that enables fast C-plane transmission mode during cordless telephone voice connections within the digital enhanced cordless telecommunications (DECT) system without degrading the voice quality. In order to perform this fast C-plane transmission mode during voice connections, one embodiment of the present invention, located within a cordless telephone handset, utilizes a silence detector circuit to determine the periods of silence within the voice data transmitted through the U-plane. By determining the periods of silence within the U-plane voice data, the present invention is able to direct the control data to be transmitted through the fast C-plane during the periods of silence.

  • Patent number: 5920731
    Abstract: An apparatus and method which overcomes connectivity limitations on PCMCIA and PC-CARD95 compatible devices by reconfiguring standard PCMCIA and PC-CARD pins for additional electrical interfaces. A detection circuit in the PC-card can detect the different interfaces. Once the different interfaces are identified, the connections to the receptacles of the PC-card connector are reconfigured such that the functional assignments of the receptacles conform with the requirements of each different interface. Thus, connection between different electrical interfaces to the physical interface of a PCMCIA-compatible device, without interference between them is possible.
