  • Patent number: 5438565
    Abstract: A system for relaying CDMA packetized data from a cell site or sites to a destination speech processor. The CDMA packetized data, is received at the cell site and is sent in its packetized form along with a destination address to a packet switch. A packet handler at the packet switch receives the CDMA data packets and forwards them on a packet bus. If the destination speech processor assigned to that call is connected to the packet bus, it recognizes its own address and processes the data packet.

  • Patent number: 4191935
    Abstract: An electrical reed spring relay construction in which a single pair of reed springs are controlled to complete simultaneously two distinct conducting paths. A pair of yoke members each comprising a pair of parallel legs connected at one end by a transverse base member are suspended by the other ends of the legs at opposite ends of an encapsulating envelope. Between the legs of each yoke member is arranged a reed spring member also suspended at one end of the envelope. The yoke assemblies are suspended at the envelope ends so that the other ends and base members overlap and are spaced apart to present the contact gaps. Upon the application of a magnetic field, the other end of the reed spring member of each yoke member is urged into contact with the base member of the other yoke member.
