Title: Network termination of a telecommunications network
Inventor: PETERS WOLFGANG
IPC: H04M11/00
Filed: 1999-09-14
Abstract: The invention has for its object to provide a network termination (NT) which is universally applicable and permits fair billing. The network termination (NT) according to the invention is characterized in that it comprises a switching facility (DET, 1, 2, 3) whereby the interface (a/b, U) on the network side is switchable from an analog one (a/b) to a digital one (U). A subscriber who needs a digital interface, for example because he wants to have two B channels of the ISDN at his free disposal, can release a digital interface (U) or have it released. A subscriber who wants only an analog access can release an analog access or have it released. To accomplish this, the network termination (NT) contains a switch (3) and a detector (DET). The switching between analog access and digital access on the network side can be effected without replacement of the network termination (NT).

Title: Mpls application to optical cross connect using wavelength as a label
Inventor: ASHWOOD-SMITH PETER J
IPC: H04B10/27
Filed: 2000-02-21
Abstract: A label switching routing protocol for establishing a datapath as a sequence of locally unique labels in an optical communications network, is provided. A wavelength on an optical cross-connect is considered as a label or one portion of a label. Timeslots may be assigned to designated wavelengths so as to form the second portion of the label.

Title: Rake receiver with embedded decision feedback equalizer
Inventor: NELSON GEORGE
IPC: H04L25/03
Filed: 2000-02-29
Abstract: The performance of a RAKE receiver for indoor multipath WLAN applications on direct sequence spread spectrum signals having relatively short codeword lengths is enhanced by embedding a decision feedback equalizer structure in the signal processing path through the receiver's channel matched filter and codeword correlator. The decision feedback equalizer serves to cancel both inter-codeword interference (ISI) or 'bleed-over' between codewords, and infra-codeword chip interference (ICI) or smearing of the energy within the chips of a respective codeword.

Patent CA-2302847-A1 (CA)
Title: One-way hinge damper
Inventor: BIVENS STEVEN L
IPC: E05D11/08
Filed: 2000-03-28
Abstract: The one-way hinge damper includes a cylindrical housing into a rotor is rotatably inserted. A gap is formed between the rotor and the cylindrical housing which is filled with silicone or a similar viscous fluid for damping the rotation of the rotor. The damping can be increased by forming longitudinal grooves or similar discontinuities in the interior surface of the cylindrical housing and longitudinal passageways on the exterior surface of the rotor.      A clutch, to which the output shaft is attached, is biased against an end of the rotor by a wave spring. Both the clutch and the end of the rotor include complementary rotationally alternating ramped surfaces and flat (or longitudinally level) surfaces. Radially extending walls are formed between the higher end of the ramped surfaces and the adjacent flat surface. When the output shaft and the clutch are rotated in a first direction, the radially extending walls of the clutch align with and engage the radially extending walls of the rotor and the rotor rotates through the viscous fluid thereby achieving damping. However, when the output shaft and clutch are rotated in a second direction, the ramped surfaces of the clutch "ramp over" the ramped surfaces of the rotor, and the rotor does not rotate, thereby allowing the clutch and output shaft to rotate substantially free of damping.

IPC: A23L19/18
Filed: 1998-07-23
Abstract: A method is described for forming dough product containing a filling. The method includes making projections on the surface of the dough product. The projections serve to isolate a volume of dough away from the main body of the dough product, so the moisture from The filling inside the main body of the dough product cannot readily migrate into the projections. The dough product with its projections attains a significant level of crispness upon frying, and retains the crispness upon reheating, even after a freeze/thaw cycle.

Abstract: A system and method for reduction of power consumed by a searchline buffer and control circuit during a CAM search-and-compare operation. The data buffer circuit samples one bit of a search word and a mask bit for driving a pair of complementary searchlines with the appropriate logic levels. The complementary searchlines are precharged to a mid-point voltage level between the high logic level voltage and the low logic level voltage during a precharge phase. The mid-point voltage level is applied on each searchline by sharing charge from the searchline at the high logic level voltage with the searchline at the low logic level voltage. Additional control logic compares the searchline data of the current search- and-compare operation with the next search-and-compare operation, to inhibit searchline precharging when both searchline data are at the same logic level.
