Abstract: An aerator includes a housing, a throttle assembly, a mixing chamber, a screen and an elastometric ring. The throttle assembly includes a first or upper throttle member and a second or lower throttle member, each of the upper and lower throttle members defining a portion of a snap element. The snap element allows for retention and relative rotation of one of said first and second throttle members in order to change the air content of the water stream from a closed aerator position which provides a substantially non aerated water stream to an opened aerator position which provides a combined water and air stream. One embodiment of a snap element being defined by upper throttle projections and a lower throttle flange whereby the lower throttle flange is urged upstream of the upper throttle projections. The lower throttle member is retained by the upper throttle member for selective rotation by the user. The lower throttle upstream projections and beveled edges facilitate the insertion of the lower throttle member into the upper throttle member for a snap engagement therewith. Selective rotation of the lower throttle member by the user varies the air volume in the water stream. During rotation the lower throttle projections change the size of the air passageways defined by an upper throttle opening to allow more or less air through the passageways. Serrated edges on the upper and lower throttle members prevent rotation of the aerator unless manual force is applied. A slot located on a downstream end of the lower throttle member allows the user to rotate the lower throttle member.

Title: Robust transmission mode
Inventor: MASHBURN HARPER BRENT
IPC: H03M13/27
Filed: 2000-08-21
Abstract: An interleaving/de-interleaving scheme for providing redundancy with both ti me and frequency diversity to data in OFDM symbols in a data transmission syste m (10). On the transmit side (12), encoded data to be modulated onto carriers in OFDM symbols is interleaved by storing the encoded data in an interleaver memory (20) and reading multiple copies of the encoded data from the interleaver memory (20) so that the encoded data copies are spread in time o n non-consecutive symbols and in frequency on non-adjacent carriers. On the receive side (14), the multiple copies of the OFDM data are received, and phase noise computations are used to combine the multiple copies (in either metric or phase angle form) into one. From the combined copies, a single metric value to be used in decoding the OFDM data is produced.

Title: Panoramic movies which simulate movement through multidimensional space
Inventor: PARK MICHAEL C
IPC: G06T15/20
Filed: 1999-05-12
Abstract: Movement through multi-dimensional space is simulated using a series of panoramic images which are projected or displayed in sequence (22). The user's direction of view, that is the selected view window, is maintained as the series of images is projected or displayed. Motion in directions other than forward or reverse is simulated by utilizing "branch" points in the sequence.  Each path from a branch point simulates motion in a different direction.  Branch points are generally indicated to a viewer by visual indicators called "hot spots"; however, branch points may also be hidden and activated in response to the viewer's selected direction of view. If a branch point is indicated by a visual indicator, a user can select motion in a desired direction by clicking on a "hot spot". In order to conserve storage space, the image representing each panorama can be stored in a compressed format (10).  Only the portion of the panorama necessary to create a "view window" that is, the portion of the image displayed in response to the user's direction of view, is decompressed at view time (21).

Inventor: ASH DARRELL LEE
IPC: H03B5/32
Filed: 2002-03-08
Abstract: To secure the benefits of a low phase noise, wide tune range SAW oscillator in noisy environments, the tunable two port SAW resonator circuit within the oscillator is employed in differential mode, connected to a differential amplifier circuit to create a differential oscillator. In the absence of any need for ground or power supply voltage level references, low phase noise/edge jitter is maintained even in hostile environments while providing sufficient tune range to track small frequency changes. The resulting differential mode SAW oscillator is thus well-suited for use, for instance, in clock recovery within SONET applications.

Title: Connexion dynamique a des serveurs d'origines multiples dans un mandataire de transcodage
Inventor: RUTKOWSKI MATTHEW FRANCIS
IPC: G06F13/00
Filed: 2000-06-28
Abstract: Procédé permettant à un mandataire de participer à une communication sécurisée entre un client et un ensemble de serveurs. Ce procédé commence par établir une première session sécurisée entre le client et la mandataire. Simultanément à la vérification de la première session sécurisée, ce procédé continue par établir une deuxième session sécurisée entre le client et le mandataire. Dans cette deuxième session sécurisée, le client demande au mandataire d'agir en tant que conduite vers un premier serveur. Ensuite, le client et le premier serveur négocient un secret maître de première session. Ce dernier est ensuite transmis par le client au mandataire, au moyen de la première session sécurisée, afin de permettre à ce dernier de participer aux communications sécurisées entre le client et le premier serveur. Après réception du secret maître de première session, le mandataire génère des informations cryptographiques lui permettant de fournir un service donné (par exemple, transcodage) de la part du client et sans la connaissance ou la participation du premier serveur. S'il est nécessaire, pendant le traitement d'une demande de client donnée, de transmettre des données d'un deuxième serveur au premier serveur, le mandataire émet une demande au client afin que celui-ci repasse au deuxième serveur par l'intermédiaire du mandataire au moyen du même protocole.
Patent CA-2378477-A1 (CA)
Title: Induction of immune tolerance
Inventor: URBAN BRITTA CHRISTINA
IPC: A61K39/00
Filed: 2000-06-30
Abstract: Methods and compositions for the induction of immune tolerance in mammalian antigen presenting cells such as dendritic cells, macrophages, monocytes and B-lymphocytes are described. Such methods and compositions involve the use of agonists of the cell surface receptors CD36, CD51, thrombospondin receptors and/or the .beta.-integrins which when exposed to an antigen-presenting cell such as a dendritic cell are able to inhibit maturation therein. Thus, the cells' ability to promote an immune response is inhibited. Tolerance to a specific antigen can be induced in antigen-presenting cells by exposure to one or more of the aforesaid agonists and the antigen. Thus, cell preparations can be prepared for administration to humans where tolerance to a specific antigen or antigens needs to be induced, for example in the case of allograft or xenograft transplants or in autoimmune disease.

Filed: 2002-04-03
Abstract: An apparatus includes a linear solenoid valve regulating an oil pressure supplied to a clutch, a hydraulic switch being switched on and off upon receipt of a switching oil pressure, and a control unit controlling the actuation of the solenoid valve. A pressure-increased side signal oil pressure is detected which results when the hydraulic switch is switched on and off while a control signal is sent to the solenoid valve to increase a control oil pressure from a predetermined lower pressure to a predetermined higher pressure, and a pressure-decreased side signal oil pressure is detected which results when the hydraulic switch is switched on and off while the control signal is sent to decrease the control oil pressure from the predetermined higher pressure to the predetermined lower pressure. When a difference between these signal oil pressures exceeds an abnormalities determination value, it is determined that the solenoid valve is abnormal.
