Abstract: The invention relates to a method of supporting communication between a first network node (AH1) and a second network node (ISR1) of a communications network (KN), to the communications network, to the first and second network nodes, and to a switch controller for the second network node for carrying out the method. Between the second network node (ISR1) and one or more further network nodes (ISR2, ISR3) of the communications network, information about label resources is exchanged using a label distribution protocol (LDP), whereby the establishment of shortcuts, each of which is formed by a direct Layer 2 connection assigned to a Layer 3 forwarding relationship, is made possible between the second network node (ISR1) and the further network nodes (ISR2, ISR3).The first network node (AH1) is preconfigured with a set of label resources. The second network node (ISR1) manages the assignment of the label resources available for a connection between the first network node (AH1) and the second network node (ISR1) and preconfigured in the first network node (AH1). The second network node (ISR1) assigns to a shortcut one of the labels from the set of label resources which are available for the connection with the first network node (AH1) and are preconfigured in the first network node (AH1), thus extending this shortcut through the second network node (ISR1) to the first network node (AH1).
Patent CA-2305254-A1 (CA)
Title: Method and apparatus for a copy-once watermark for video recording
Inventor: RYAN JOHN O
IPC: H04N7/26
Filed: 1998-10-01
Abstract: Method and apparatus for "copy-once" of a digital video signal uses a watermark in the video signal. The embedded watermark has two versions: one indicates copy-never and a second indicates copy-once, the difference being a single watermark bit. The watermark carries additional bits representing a digitized attribute (image characteristic) of a particular video frame of the video signal, for instance an average value of the amplitude of a video field.  The frame whose attribute is carried in the watermark has a field (or frame) marker, which is a special signal located in the overscan portion of the frame. A compliant video recorder verifies the watermark and the copy-once bit (48, 54), extracts the associated attribute from the watermark (56), and compares (68) it to the measured attribute (58) of the marked video frame.  Only if the extracted attribute value and the measured attribute value match, is recording enabled. During the recording process (70), the frame markers are stripped (72), preventing second generation copies of the recorded video signal, and the copy-once bit is set to copy-never.

Abstract: A training unit (100) generally includes a processor (102), a magnetic field sensor (121), a plurality of control switches (110, 114, 118), and a message and data output device (105). Placing a PEIS magnet (20), constructed in accordance with the ISO/WD 14994 standard, adjacent to or in contact with the training unit activates the magnetic field sensor, a condition detectable by the processor. Activation of the switches determines which of three modes the training unit will operate. In an instructional mode (110), the process provides instructional messages to the operator via the message and data output device, which preferably includes a display (104) and an audio speaker (108). In a coached mode (114), the training unit informs the operator when to place the magnet adjacent to or in contact with the training unit and when to remove the magnet in accordance with the timing intervals of the PEIS entry code. In a practice mode (118), the operator initiates and completes the entry code using a PEIS magnet without coaching. The processor detects the presence of the PEIS magnet, and determines whether the operator correctly performed the entry code. If the operator completes the entry code in either the coached or practice modes, a simulated ECG waveform indicative of a patient's surface ECG upon successful completion of an entry code is shown on the display.

Title: Non-volatile mems micro-relays using magnetic actuators
Inventor: JIN SUNGHO
IPC: H01H51/22
Filed: 2000-10-06
Abstract: An actuation device employing square-loop latchable magnetic material having a magnetization direction (polarization) capable of being changed in response to exposure to an external magnetic field is disclosed. The magnetic field is created by a conductor assembly with non-solenoid configuration. Once the magnetization direction of the material is so changed, the external magnetic field is no longer required to maintain the new magnetization direction. The latchable magnetic material is disposed on the mobile electrode of a switching device, and another magnetic material is disposed in spaced relation to the latchable magnetic material on a stationary electrode or surface. By applying an electrical current to a conductor assembly arranged proximate the latchable material, a magnetic field is created about the latchable magnetic material, to change the magnetization direction and thereby enable the attraction or repulsion of another magnetic material located on the stationary electrode. The resulting relative displacement of the mobile and stationary electrodes effects the selective connection or disconnection of electrical contacts carried on or associated with the respective electrodes of the actuation device without requiring additional power in order to maintain the switched state of the electrodes.
