Title: Telecommunications inter-exchange measurement transfer
Inventor: WALLENTIN PONTUS
IPC: H04W74/00
Filed: 1999-03-02
Granted: 2011-05-17
Abstract: Telecommunications network decision making (such as call admission and call congestion control) utilizes as input, not only information in the cell where the call is setup, but also cell condition information from cells which neighbor the cell where the call is setup. The cell condition information from neighboring cells is obtained even in situations in which the neighboring cell is controlled by another exchange, e.g., another radio network controller (RNC). In an illustrated embodiment, the cell condition information utilized by the decision making includes measured data taken over at least a multi-connection portion of cell, one example of which is radio interference information. The cell condition information utilized in the network decision making is transmitted between exchanges (e.g., between radio network controllers (RNCs)) using common channel signaling.

Abstract: L'invention concerne un comprimé se désintégrant dans la bouche, qui comporte (1) des granules fins présentant un diamètre moyen de particules égal ou inférieur à 400 µm, ces granules fins renfermant une composition revêtue d'une couche d'enrobage gastro-résistante. Ladite composition contient une quantité égale ou supérieure à 10 % en poids d'une substance acide-labile physiologiquement active; et (2) un additif. Le comprimé présente une capacité de désintégration ou de dissolution supérieure dans la cavité buccale, de sorte qu'il peut être utilisé pour traiter ou prévenir diverses maladies, et, comme tel, peut être administré facilement sans eau à des personnes âgées ou à des enfants. De plus, comme le comprimé de l'invention contient des granules fins présentant un diamètre moyen des particules tel qu'il ne produit pas de sensation rugueuse dans la bouche, il peut être administré facilement sans inconfort au moment de l'administration.

Title: System and method for delivery of short message service messages to a restricted group of subscribers
Inventor: ALPEROVICH VLADIMIR
IPC: H04W88/02
Filed: 1999-05-03
Granted: 2010-01-05
Abstract: A telecommunications system and a method is disclosed for encapsulating header information associated with a Short Message Service (SMS) message within that SMS message, which can then be sent over a broadcast channel. This header information can contain, for example, additional information regarding the intended recipients of the SMS message. For example, a business with 100 employees may want to be able to broadcast a SMS message to all employees, but not to anyone else. Therefore, in this case, the header information can indicate "private" and include a unique user group identification (ID) code. A Subscriber Identity Module (SIM), or other memory, within each of the mobile terminals within the predefined group can contain a message application, which can compare the received group ID to a group ID stored in the SIM, and determine whether the message should be displayed on the mobile terminal.

Title: Improvements in electrical protection and control systems
Inventor: PRICE RICHARD THOMAS
IPC: H02J13/00
Filed: 2001-01-31
Granted: 2012-01-03
Abstract: A protection and control system incorporates status acquisition apparatus (100) for use in monitoring the status of a device in the protection and control system, such as a protection relay in a high voltage electrical circuit. The status acquisition apparatus comprises an conversion circuit (101) which converts an input voltage to a pulse width modulated signal and a comparison circuit (103) which monitors the pulse width modulated signal to determine the status of the device. The mark- space ratio of the pulse width modulated signal decreases as the input voltage is increased to minimise power dissipation over a range of input voltages. The status acquisition apparatus may form an integral part of a protective switching device, although other applications are envisaged.

Title: System and method for inverting automatic frequency control (afc)
Inventor: KEMENCZY ZOLTAN
IPC: H04L27/00
Filed: 2001-11-21
Granted: 2005-09-27
Abstract: A system and method for inverting automatic frequency control applied to a reference signal used to process an input signal is disclosed. When receiving an input communication signal, a receiver controls the frequency of the reference signal to compensate for frequency differences between a transmitter and a local oscillator in the receiver. The frequency control applied to the reference signal causes frequency variations in a resultant signal processed signal when the input signal is processed using the reference signal. The frequency of a second reference signal is controlled such that further processing of the resultant processed signal removes effects of the frequency control applied to the reference signal. The processing which applies frequency control to the reference signal is performed in real time while the inversion process is performed in a separate processing section.

Title: Process for the production of furfural from lignosulphonate waste liquor
Inventor: ZEITSCH KARL J
IPC: D21C11/00
Filed: 2000-04-14
Granted: 2009-06-16
Abstract: A process for the production of furfural from lignosulphonate waste liquor which contains pentose is described, the process essentially comprising the maintenance of a boiling condition of the liquor at predetermined pressures for a sufficient time to convert the pentose to furfural and for the furfural produced to be removed without reacting with pentose, lignosulphonate or itself. Hot air or some other gas under pressure or hot mercury may be used to maintain the boiling of the liquor to ensure that the furfural produced transfers from the liquid to the gas phase and is transported from the reactor in the gas stream. Apparatus for carrying out the process includes a columnar reactor (4) with means (8) to control the pressure, an inlet for preheated liquor, an inlet for hot air under pressure at a low level, an outlet for spent liquor and an outlet for the gaseous phase, from which the furfural is recovered.

Title: Method for downloading software
Inventor: CUNDALL JOHN
IPC: G06F21/12
Filed: 2000-02-16
Granted: 2007-05-01
Abstract: According to the present invention there is provided a method for downloading software from a mobile network operator to a mobile phone user. The downloaded software can be new network services or user specified applications software or user specified information. The method requires the downloaded software to written as Java classes capable of running on a Java Virtual Machine. All the Java classes can be continuously broadcast at a relatively modest data rate. In an enhanced mode a list of services available for downloading is broadcast over the network more frequently then the actual services themselves. The user then selects which service he wants and only that one is downloaded. Payment can be on a subscription or pay-per-use basis. The method could also be adapted to work with one of the new digital broadcasting platforms such as DAB or DVB as a means for delivering the Java classes. This would significantly increase the volume of data which could be downloaded thus increasing the number of new services or information which could be accessed.

Abstract: A method of connecting a mobile communications device (2,4,6) to an internet site, wherein a call from the mobile communications device (2,4,6) to the internet site is routed automatically via a local service provider. Hence, as the mobile communications device (2,4,6) roams from country to country, the call to the internet site is routed automatically via the service provider situated in the country in which the mobile communications device is currently located. This results in only a local call being required, since the local service provider provides access to its internet gateway. This avoids the need for an international call back to the user's home internet service provider.
