Title: Procede de categorisation des fournisseurs multiples dans un environnement de services de communication sans fil
Inventor: RAFFEL MICHAEL ALLEN
IPC: H04W24/00
Filed: 1997-06-24
Abstract: Un dispositif de communication localise un fournisseur de services préféré dans un environnement de fournisseurs de services multiples au moyen d'un programme de recherche de bandes de fréquence. Ce dispositif de communication repère initialement un fournisseur de services moins préféré dans une première bande de fréquence. Tout en conservant ce repère avec le fournisseur de services moins préféré, le dispositif examine plusieurs bandes de fréquence dans l'ordre spécifié par le programme de recherche de bandes de fréquences. L'examen d'une bande de fréquence consiste à diviser la bande de fréquence en un nombre important de bandes secondaires et à localiser le signal le plus fort supérieur à un seuil à l'intérieur de la bande secondaire en cours d'examen. Cet examen continue jusqu'à la localisation d'une deuxième bande de fréquence possédant un fournisseur de services de plus grande préférence. Le dispositif de communication repère alors ce dernier fournisseur . La catégorie du fournisseur de services peut être identifiée et affichée sur le dispositif de communication.

Title: Receiver for adjusting sync levels in vsb systems
Inventor: KRISHNAMURTHY GOPALAN
IPC: H04N5/46
Filed: 1997-10-03
Abstract: A receiver for receiving a cable and terrestrial digital signals of differing VSB modes where the data levels of the various signals have a desired relationship that enables simple data level slicing and error determination.  Some of the signals have sync levels that do not conform to the desired relationship and the receiver includes a comb filter for reducing interference when receivingan 8VSB terrestrial signal. The mode of the received signal is determined and a correction factor is applied to the syncs of the signals as needed to reestablish the desired relationship. Operation of the comb filter results in additional levels and a disruption of the desired relationship. For such cases, the comb filtered data levels are modified to make them a subset of the VSB 16 data levels. The modifications are accomplished in feedback paths of the phase tracker after the circuit equalizer and do not affect the data levels passed to the next stage.

Title: Tilt mechanism for infant care apparatus
Inventor: DYKES CHRISTOPHER A
IPC: A61G11/00
Filed: 1999-05-13
Abstract: An infant care apparatus that has a infant bed tilt mechanism that can be accessed by the user in close proximity to the infant mattress and at the mattress level. When the infant care apparatus is an infant incubator, the tilt mechanism is operable internal of the infant compartment. The user can thus be carrying out some procedure on the infant within that infant compartment of the incubator or at the level of the infant bed of an infant warmer and be able to alter the tilt angle of the infant bed without breaking the semi sterile conditions surrounding the infant and its close proximity by manipulation of a actuating mechanism that is situated at the level of the infant bed and in close proximity to the infant. The tilt mechanism itself has a lead screw rotatable mounted to the infant bed and which passes through a threaded nut that is resiliently affixed to the base of the incubator or infant warmer. A braking mechanism allows the user to unlock the lead screw quietly so that it is free to rotate smoothly to adjust the tilt angle of the infant bed and then relock the lead screw quietly to prevent its rotation with respect to the infant bed to lock the infant bed into that new tilt angle.

Title: Non-uniform memory access (numa) data processing system that holds and reissues requests at a target processing node in response to a retry
Inventor: BAUMGARTNER YOANNA
IPC: G06F15/17
Filed: 1999-08-12
Abstract: A non-uniform memory access (NUMA) computer system includes at least a local processing node and a remote processing node that are each coupled to a node interconnect. The local processing node includes at least a processor and a local system memory, and the remote processing node includes at least a processor having an associated cache memory, a local system memory, and a node controller that are each coupled to a local interconnect. In response to receipt by the node controller of a request transaction transmitted from the local processing node via the node interconnect, the node controller at the remote processing node issues the request transaction on the local interconnect. If the request transaction receives a retry response at the remote processing node, the node controller does not immediately return the retry response to the local processing node. Instead, the node controller reissues the request transaction on the local interconnect at least once, thus giving the request transaction another opportunity to complete successfully. In one embodiment, the request transaction is reissued on the local interconnect of the remote processing node until a response other than retry is received or until a retry limit is reached.

Patent CA-2298599-A1 (CA)
Inventor: WEBER JEAN-PIERRE
IPC: H04J13/00
Filed: 1998-07-30
Abstract: In a fiberoptical network, for example in a LAN, spread spectrum modulation is used, for example CDMA, by providing an electrical digital data signal to spreading means comprising a multiplier (41) also receiving the spreading code. Then a modulation is made of the spread signal at radio frequencies, the signal being multiplied (49) by a subcarrier wave generated in an oscillator (47), whereby the data signal is carried on an RF subcarrier. A control channel signal from a control unit (53) is added (51) to the modulated signal, so that the control signal will be located in the baseband. The added signal is converted (55) to an optical signal transmitted on an output fiber. The control channel signal can be TDMA-modulated using collision detection. Making spectrum spreading in the electrical domain allows the use of standard components developed for example for mobile telephone systems. No wavelength control and no optical filters are necessary, which allows a low cost system to be constructed. Alternatively the spread-spectrum data signal can be located in the baseband and the control channel on a subcarrier or both the data and the control channel can be put on subcarriers.
