Abstract: Call connections by way of the Internet (internet telephony) are less expensive than ones by way of an open telephone network.  However, no fixed transmission rates are guaranteed in. the Internet, which can lead to losses in the quality of transmitted speech signals.  A device (V) for establishing a call connection between two subscriber terminals (T1, T2) has a first interface (IF1) to a packet-switched data network (INET) and means (IP, KOMP) for establishing connections by way of the packet-switched data network (INET) as well as a second interface (IF2) to a connection-oriented telecommunication, network (PSTN), in which a transmission channel with a predetermined transmission band width can be furnished.  By means of a monitoring device (MON), the device (V) determines a current data throughput in the data network (INET).  A control device (SW) of the device (V) compares the current data throughput with a predetermined threshold value and controls the establishment of connections in such a way that the call connection is established by way of the data network (INET) when the data throughput lies above the threshold value and is established by way of the telecommunication network (PSTN) when the data throughput lies below the threshold value.

Title: Apparatus for controlling relative rotation
Inventor: GRAY BENJAMIN
IPC: E21B7/06
Filed: 1998-12-09
Abstract: An apparatus for controlling rotation of an outer sleeve member relative to an inner cylindrical duct member is used in a drilling system for controlling steering of a downhole drilling tool. The apparatus includes an annular swash plate pump and a stack of annular brake disks in the space between the members. The pump is driven by the rotation to pump fluid into a supply cylinder driving the brake. An orifice controls escape of the fluid from the chamber at a controlled rate.  The rate is controlled to maintain a balance between the pumping rate and the brake pressure to keep the rotation at a required rate. The apparatus is used in the drilling system which includes a shallow bend in the drilling tool and a system for rotating the bent drilling tool slowly about a longitudinal axis of the drilling tool while the drill bit rotates more rapidly. The controlled orifice further allows the slow rotation to be halted at a predetermined orientation of the bend axis so as to effect a change in drilling direction.

Title: High speed decoder and decoding method
Inventor: TOWNSHEND BRENT
IPC: H04L5/14
Filed: 1995-12-04
Abstract: A new data communication system is described which enables data transmission over existing telephone lines at rates higher than possible with existing methods, including conventional modems.  By using a novel asymmetric configuration of the two communicator endpoints, the currently-accepted maximum theoretical limits on the data rate are no longer applicable.  One endpoint is connected directly to a digital telephone network, whereas the other endpoint uses a conventional telephone connection.  This reduces the transmission problem to compensation for a single telephone line interface and a single analog local loop.  Means of providing this compensation and the required clock synchronization were also created, enabling a practical implementation of the system.          The new system can achieve rates up to 64,000 bits-per-second and has broad utility in several  active areas including wide-band audio transmission, video transmission, networking, facsimile transmission,  and remote computer access.
