Abstract: A television system allows a viewer of a text-enhanced television program to pause (via 28) the program at a particular frame, browse the enhancements at his or her leisure, and then resume viewing the program from that frame, without losing continuity of the video and enhancement portions of the program content. This is accomplished by time-shifting (52) the television program for later playback.

Title: Railway locomotive ecp train line control
Inventor: KULL ROBERT C
IPC: G08C/
Filed: 1999-11-23
Abstract: An interface adapter is provided between the locomotive MU cable and the ECP  trainline permitting ECP data from the lead locomotive to be transmitted via the MU  cable on trailing locomotives to a train of ECP cars. On the lead locomotive, the HEU  Echelon interface is on a suitable line in the MU cable instead of the separate ECP  tramline such that trailing locomotives do not require a separate ECP trainline. The adapter generally employs two transceivers configured as back-to-back repeaters to bridge ECP  data between the locomotive MU cable and the ECP trainline. A DC-DC converter can be used to provide the ECP trainline voltage, either as 230 VDC or as a lower voltage. In lower voltage systems the converter may be replaced by a voltage regulator, or may be eliminated. In any case, an inductor is employed on the output to provide a high impedance to the overlay transceiver.

Patent CA-2294966-A1 (CA)
Inventor: ASHER WILLIAM E
IPC: C10L1/22
Filed: 1998-06-30
Abstract: A liquid can be marked for identification purposes with at least first and second miscible markers. The markers are mixed in the liquid so that the ratio of the concentration of the first marker to the concentration of the second marker is substantially equal to a predetermined value. Thus, by comparing the ratio of the measured concentration of the first marker to the measured concentration of the second marker with predetermined values the liquid can be uniquely identified. In one embodiment, a multi-channel infrared fuel analyzer (10) is disclosed for identifying fuel samples in an examination vessel or flow tube (12). Radiation source (16) is provided on one side of tube (12) for illuminating the flowing fuel (14). Detectors (20A, 20B, and 20C) assigned to specific channels, are provided on the other side of the tube for detecting absorption associated with the presence of an assigned fuel marker. The infrared light source and detectors can be connected to a processor and control unit (22) for initiation of testing, for processing of detection signal from the detectors, and for display of readout information. Processor and control unit (22) can include a look up table (23) for storing information about marking patterns, a comparison element (35) for comparing measured values with values supplied by look up table (23), and a display (30).

Patent CA-2295390-A1 (CA)
Inventor: O'SULLIVAN MAURICE S
IPC: H04B10/532
Filed: 2000-01-13
Abstract: A binary signal is encoded to produce a three-level encoded signal having reduced bandwidth and small low frequency and d.c. components, e.g. using modified duobinary encoding, the encoded signal directly modulating a semiconductor laser to produce a frequency modulated optical signal, which is passed through an interference filter to provide two-state amplitude modulation from the three-state frequency modulation for direct recovery of the binary signal by an optical receiver, the interference filter providing constructive and destructive interference for frequencies corresponding to binary one and zero bits respectively. An array transmission system can be provided by combining multiple such frequency modulated optical signals, from multiple lasers with respective central frequencies and respective encoders for multiple binary signals, using an array waveguide which also serves as a channel frequency filter, with a single interference filter. Polarization modulation instead of frequency modulation, and external modulation of an optical signal from an optical source, are also described.

IPC: G06F21/00
Filed: 1998-09-21
Abstract: This invention relates to metered usage, and prevention of piracy, of computer software and other intellectual property existing in electronic digital format.   The end result of the invention enables soft--ware-on-demand and software subscription services by employing a transformation filter (104) to perpetually regulate, meter, and charge for the usage of software products. The apparatus is implemented as a virtually integral part of the operating system that monitors and "filter" all read, write, and open/execute acccess to and from the I/O devices (106). As the protected material is being accessed, the transformation filter (104) positions itself in the path required for loading the material through the file system and application layers. The material enters the transformation filter (104) in its encrypted state and is decrypted in real-time as it goes through. The material is then handed over to the operating system components (107/108) to fulfill the user access requests.

Title: Expanded film base reinforcement for papermaker's belts
Inventor: ROMANSKI ERIC R
IPC: D21F3/00
Filed: 2000-05-17
Abstract: A resin-coated endless belt for a long nip press has a base which is a polymeric film structure in the form of an endless loop with an inner surface, an outer surface, a transverse direction and a longitudinal direction. The polymeric film structure has a plurality of perforations which may be aligned in one or both of these directions. The polymeric film structure is stretched in the presence of heat to orient the molecular chains in the unperforated intervals between the perforations to provide the structure with tenacity and resistance to further stretching. At least the inner surface of the base (polymeric film structure) is coated with a polymeric resin material, such as polyurethane. The polymeric resin material coats the base and upon curing, forms a mechanical interlock therewith by virtue of the perforations, and renders it impermeable to oil and water. In addition to being useful for a long nip press, the belt may also be used in other papermaking applications, for example, as a calender belt on a calender of the shoe type or on a calender having two or more rolls, or as a transfer belt.

Abstract: In an electrosurgery system having a radio frequency generator and an instrument with a treatment electrode, the generator includes a circuit for sensing thermionic emission from the electrode as means of controlling the supply of radio frequency power to the electrode. Thermionic emission is sensed by detecting d.c. voltage at the output of the generator, using a detector with an isolated output, and generator output power is controlled so as to limit the d.c. voltage to a predetermined threshold.  Accordingly, the temperature of the electrode can be limited to avoid electrode destruction.  the invention also has application to reducing nerve stimulation due to electrosurgical treatment.
