Title: Dual hubbing in a bidirectional line-switched ring transmission system
Inventor: KREMER WILHELM
IPC: H04Q11/04
Filed: 1993-04-21
Granted: 1999-11-02
Abstract: Communications circuit connectivity in a bidirectional line-switched ring transmission system is continued in the presence of the failure of a first ring node for communications circuits terminated in the ring node which are redirectable to an alternate (dual hubbing) ring node. The communications circuits are redirected by establishing a bidirectional communications circuit to the alternate ring node. In one example, redirection of the communications circuits is further realized by not squelching communications circuits terminated in the failed ring node in a ring node adjacent the failed ring node on one prescribed side which normally would have been squelched, while squelching communications circuits terminated in the failed ring node in a ring node adjacent to the other side of the failed ring node.  This allows the redirectable communications circuits to be loop back switched so that they may be redirected to the alternate ring node. Then, the alternate ring node directly intercepts the redirected communications circuits. This is realized by providing provisioning information to the ring nodes which includes the identity of all communications circuits active in the ring and whether there is an alternate ring node to which any of the communications circuits may be redirected.

Title: A method of detecting and discriminating between nucleic acid sequences
Inventor: WALLACE ROBERT B
IPC: C07H21/04
Filed: 1992-06-17
Granted: 2003-08-26
Abstract: The present invention is directed to a method for detecting the presence or absence of any specific target nucleic acid se-quence contained in a sample. The target sequence can be present in the sample in a relatively pure form or as a component of a member of a mixture of different nucleic acids. The method of the invention utilizes a novel primer design. The sequence of the novel primer is composed of two portions, the 3' portion is a primer specific for the desired nucleic acid sequence and the 5' por-tion is complementary to preselected nucleic acid sequence. Extension of the 3' portion of the primer with a labeled deoxynucleo-sides triphosphate yields a labeled extension product if, but only if, the template includes the target sequence. The labeled exten-sion product is detected by hybridization of the 5' portion to the preselected sequence. The preselected sequence is preferably bound to a solid support as one member of a grid having a group of sequences.

Abstract: It is possible to determine whether the correct business form parts have been properly provided in an outgoing package (e.g., mailing envelope) containing a plurality of parts, utilizing a magnetic detector capable of detecting magnetic toner within the package. Dense patterns of magnetic toner are imaged on portions of each of the business form parts, located at different positions on different parts. Then the parts are formed into a package (as by folding about fold lines into a self-contained mailer, or inserting into a mailing envelope), and the package is moved with respect to a magnetic detector. The magnetic detector senses the dense magnetic toner patterns within the package to determine whether all the correct parts are properly in the package by determining whether all business form parts in the package have the detectable magnetic toner indicia patterns on the predetermined portions. The dense patterns of magnetic toner are preferably in the form of solid toner rectangles disposed in a straight line configuration, and the package is moved in a straight line with respect to the detector. A multi-part business form is also provided, having dense patterns of magnetic toner and less dense alphanumeric indicia on the plural plies of the business form, which may be a self-contained mailer or parts inserted into a mailing envelope.

Patent CA-2139999-C (CA)

IPC: B61L1/16
Filed: 1995-01-11
Granted: 2003-01-07
Abstract: An axle counter which compares axle passage pulses generated in an electromagnetic rail contact with a predetermined threshold value and, when this threshold value is exceeded, feeds an axle counter pulse to presence-of-trains indicating equipment, is equipped with overwritable memories (SMA, SMI) for storing this threshold value. In response to a setup command entered manually by depressing a key or transferred from a distant control facility (STW), the memories can be overwritten with a current axle passage pulse value or a statistically determined value corresponding to an average axle passage pulse. This eliminates the need to reposition the rail contact at regular intervals and permits this repositioning to be replaced by an adaptation of the threshold value to the axle passage pulses, which change as a result of rail wear, for example.

Granted: 1999-06-01
Abstract: In a mobile radio communication system employing a time-division multiple transmission scheme, having a plurality of base stations and a plurality of personal stations, an arbitrary base station, when detecting a pilot signal transmitted from any master base station in the mobile radio communication system, acts as a slave base station which does not transmit its pilot signal but transmits and receives a common control signal to and from a personal station utilizing a frequency channel occupied by the pilot signal.  On the other hand, when not receiving the pilot signal, the base station searches for an available frequency channel, and acts as a master base station which transmits its pilot signal on the available frequency channel to occupy the frequency channel, and transmits and receives the common control signal to and from a personal station on that frequency channel.

Abstract: The present invention relates to sulfonate containing water-dispersible or water-dissipatible sulfopolyester compositions.  The sulfopolyesters utilize at least two dicarboxylic acids, one of which is a naphthalene dicarboxylic acid.  This combination of dicarboxylic acids allows for the sulfopolyesters to maintain glass transition temperature (Tg) of greater than 89 °C and exhibit lower melt viscosities than sulfopolyesters containing all naphthalenediyl units or all isophthtaloyl units. The sulfopolyesters of this invention are useful in applications where improved heat and blocking resistance is required.

Title: Television signal recording/reproducing apparatus and method with dc shifter
Inventor: KANOTA KEIJI
IPC: H04N7/00
Filed: 1996-06-04
Granted: 2005-09-06
Abstract: Recording and reproducing a television signal with a DC shifter prevents compression distortion of a PAL plus television signal. The PAL plus television signal includes a vertical resolution signal for enhancing vertical resolution which vertical resolution signal is included in the same compression blocks as some of the component video signals. Such compression blocks are shifted to a DC set up value so that the signals within those compression blocks do not have varying DC offsets which otherwise could result in compression distortion. Similarly, upon reproduction, the DC set up value is removed after decompression and the original television signal is restored with complete vertical resolution.
