Title: Method and apparatus for accessing a cellular radiotelephone system without system identification comparison
Inventor: FEHNEL MICHAEL D
IPC: H04W48/12
Filed: 1995-09-06
Granted: 2005-05-10
Abstract: A cellular radiotelephone system is accessed by a cellular radiotelephone without requiring System IDentification (SID) comparison during access.  Access is performed by eliminating a rescan of Access Channels during access and using the Combined Paging and Access Channel which was identified during initialization for system access.  Alternatively, the Access Channels may be rescanned upon an access request and a comparison of the Digital Color Code with the initially scanned channels is made.  If the compared Digital Color Code matches, the identified channel is used for system access regardless of its SID.

Abstract: In a connection-oriented network where ATM nodes are interconnected by links, periodically updated link status information of the network is stored in a database to indicate resource constraints of the network links. Responsive to a connection request specifying multiple QOS parameters, a first path to a destination is selected and a first signaling message is transmitted continuing routing data of the first path toward the destination if resource constraints of the first path satisfy all the specified QOS parameters. If the transmission of the first signaling message is unsuccessful or the resource constraints of the first path do not satisfy all the specified QOS parameters, then a second path to the destination is selected according to contents of the database that correspond to one of the specified QOS parameters, and a second signaling message continuing routing data of the second path is transmitted toward the destination.

Title: Method of correcting nonlinearities of an amplifier, and radio transmitter employing a method of this type
Inventor: PELTIER JACQUES
IPC: H03F1/32
Filed: 1997-03-19
Granted: 2004-06-22
Abstract: In order to correct nonlinearities of an amplifier (20) which receives a radio signal (d') and produces an amplified radio signal representing an input complex digital signal (m), a predistortion table, associating a value of a predistorted complex digital signal with each value of the input complex digital signal, is stored, and the predistorted complex signal (d) is modulated in order to obtain the radio signal addressed to the amplifier. In an adaptation period, a fraction (r') of the amplified radio signal is demodulated in order to obtain a demodulated complex signal (r) which is compared with the input complex signal, with which the predistorted complex signal modulated in said adaptation period is associated, in order to update the predistortion table. The predistortion table is updated on the basis of mean values calculated from blocks of samples of the input complex signal and of the demodulated complex signal, which are stored in the adaptation period.

Filed: 1997-12-05
Granted: 2000-10-31
Abstract: A method is disclosed which brings together a combination  of  special  IN  features  and  techniques  to allow  Centrex  stations  supported  by  a  plurality  of central  office  switching  systems,  each  at  different locations, to function from the customer's perspective as though  they  were  served  by  a  single  central  office switch.  The key to Virtual Wide Area Centrex is a total separation of  the  telephone  numbers  seen  and used by customers   (Customer  Number  Address - CNA)   from  the telephone numbers used internally by the network for call routing purposes  (Network Node Address - NNA), such that there  are  two  separate  and  distinct  numbering  plan domains.  A central database, interconnected with each of the Centrex switches, maintains the mapping between CNA and NNA.   This database is called upon, as required, to do both forward and reverse translations - i.e., from CNA to  NNA  and vice-versa.  The  net  result  is  that  CNA identify people  (e.g.,  a customer's  specific employees and agents) whereas NNA identify locations (e.g., offices and conference rooms).   This permits an environment in which individuals may move from one physical location to another, regardless of the serving central office switch, while  keeping  their  CNA  and  their  network  access privileges.

Abstract: In a cordless telephone apparatus including a base unit and a sub unit connected with each other by wireless, the base unit has a memory for storing therein telephone number data which are referred to from the sub unit.  When the base unit is busy, the transfer of a calling signal between the sub and base units is not performed.  The access from the sub unit to the memory of the base unit is always permitted.   The memory includes a callers area in which the telephone numbers  of callers of received calls and the reception times of the calls are stored and a directory area  in which frequently  called  telephone numbers and the number of placing calls of the numbers are stored.  The telephone numbers in the callers area are retrieved based on the reception times.   The telephone numbers in the directory area are retrieved based on the numbers of placing calls.  By adding the number of placing calls of the telephone number stored in the callers area to the number of placing calls of the telephone number stored in the directory area, the telephone  number  retrieval  from  the  directory  area  functions correctly.  Moreover, by using the cordless telephone apparatus as a terminal apparatus of a private telephone system,  data stored in a main apparatus of the system are referred to from the sub unit of the terminal apparatus.

Abstract: Cette invention concerne un débitmètre à dérivation permettant de mesurer le débit d'une matière dans un conduit. Une chute de pression optimale peut être générée dans le débitmètre (104) en couplant la sortie (107) de matière du débitmètre à la gorge d'un venturi (108) disposé à l'intérieur du conduit (101). Cette chute de pression accrue permet d'améliorer le débit de la matière à travers le débitmètre, et d'accroître la précision et la sensibilité de ce dernier, ainsi que sa capacité à mesurer des débits massiques de matières de faible densité, tel que du gaz. Le rapport entre le débit de la matière dans le débitmètre et le débit dans la conduite peut être dérivé. Les informations concernant le débit de la matière dans le conduit sont obtenues, pour des matières possédant une viscosité variable, à l'aide d'un capteur de pression différentielle (134), lequel mesure la chute de pression dans le débitmètre, puis transmet ces informations à des instruments qui vont en dériver, avec une plus grande précision, les informations concernant le débit de la matière dans le conduit. Dans un autre mode de réalisation où l'on n'utilise pas de venturi, on procède de la même manière afin de dériver le rapport du débit de la matière entre le débitmètre et le conduit, puis de dériver le débit total de la matière dans le conduit.
