    摘要： A method and apparatus for preprocessing digital voice data enroute to or from a Telephone's CODEC. The apparatus supports a CODEC directly connected to an internal bus and using a separate CODEC clock and sync signal to control transfers between a telephony link/internal bus interface and the CODEC. According to an embodiment of the present invention, an auxiliary processing device (connected to the internal bus side of the phone) is provided with means to process the digital voice information before sending it uplink or to the CODEC. This is accomplished without changing the position of the incoming voice field.

    摘要： A method and apparatus for transferring data between telephony communications lines having different frame transmission rates. A downlink data frame according to a first protocol (e.g. a ROLMlink frame) is transmitted, at a first data rate, from a private branch exchange (PBX) to a telephone's network interface. One or more fields of data from this frame are collected in shift register which is internal to the interface. After collection, the data is injected into a downlink data frame of the telephone's internal protocol (e.g. a GCI frame), which is being transmitted on the telephone side of the interface at a second data rate (different from the first data rate). Simultaneously with the injecting, one or more fields of data from an uplink data frame of the telephone's internal protocol are shifted into the same register for later injection into an uplink data frame, of the external protocol, destined for the PBX. This later injection occurs simultaneously with data from another downlink data frame, from the PBX side of the interface, being collected in the register.

    摘要： A magnetic fluid seal is provided located in an L-shaped holder for defining the location of the seal relative to the shaft and bore. The magnetic seal is located inside the knee of the L-shaped holder, with a small magnetic fluid filled gap between the end of the magnetic seal and the fixed shaft. Immediately below the pieces and magnet of the magnetic seal is a gasket which provides for an airtight seal between the edge of the L-shaped holder and the outer wall or rotor. The entire assembly is held reliably in place by a shield which is typically press-fitted in place. The shield is designed to incorporate two key design features; (1) the outside diameter of the shield is a press-fit to the inside of the bore defined by the rotor; and (2) at its final axial location the shield presses vertically against the gasket, whereby the gasket is compressed to an approximate degree (for example about 50%) to provide press fitted contact covering the opening between the seal face outside diameter, and the bore of the rotor, thus providing a complete airtight seal at the outer diameter of the seal.
