Patent CA-2277074-C (CA)
Inventor: KARASSIK NANCY M
IPC: A61K/
Filed: 1997-12-16
Granted: 2003-02-11
Abstract: The present invention is directed to a clear antiperspirant or deodorant gel composition which exhibits reduced staining while retaining excellent aesthetic attributes and efficacy. The gel composition is a water-in-oil emulsion having a viscosity of about 50,000 to 250,000 cP, preferably about 100,000 to 200,000 cP. The water phase comprises about 75 to 90 % of the composition and contains a deodorant or antiperspirant effective amount (e.g.  about 3 to 25 %) of an antiperspirant active dissolved therein. The oil phase comprises about 10 to 25 % of the composition and contains a silicone oil and a polyether substituted silicone emulsifying agent. The silicone oil comprises a mixture of a non-volatile silicone, preferably a non-volatile linear silicone, and a volatile linear silicone. It has been found that reducing the amount of non-volatile silicone in the known gel composition to a relatively low level (e.g. below about 5 %) and adding an amount of volatile linear silicone to the composition (e.g. above about 2 %, preferably above about 5 %) substantially improves the non-staining properties of the composition.

Title: F-sin (.theta.) lens system and method of use of same
Inventor: THIBAULT SIMON
IPC: G01J3/18
Filed: 1999-08-19
Granted: 2008-06-10
Abstract: An optical system for focusing an incident light so as to obtain a linear output (as a function of the wavelength, or of the order of diffraction, or of the grating spacial frequency or of the inverse of the index of refraction) comprises a diffraction grating and a lens, or a group of lenses, having a f-Sin(.theta.) characteristic,  where f is the effective focal length of the lens, or group of lenses, and .theta.  is an output angle of the light exiting from the diffraction grating. Therefore, a light incident on the diffraction grating reaches the lens, or the group of lenses, and results in a linear output.  Using the present invention in a spectrometer reduces the time consuming calibration process required and renders it easier because of the linear output between wavelength and pixels positions. The lens, or.group of lenses, has a diffractive, refractive or reflective property, or any combination thereof. The incident light can be a collimated, converging or diverging beam. The diffraction grating can be a plane, concave or convex grating.

Title: Voice-over-ip enabled chat
Inventor: BURG FREDERICK MURRAY
IPC: H04M7/00
Filed: 2000-05-30
Granted: 2005-12-20
Abstract: A network-based system and method for providing anonymous voice communications using the telephone network and data communications links und er the direction of a Call Broker and associated network elements. A user (the call initiator) present in a text chat room session establishes a data connection to Call Broker and, after qualifying for access (e.g., using credit card information) and providing a callback number, receives voice session information and participant access codes for each desired participant in a voice call. The initiator causes session information and participant codes to be passed to one or more selected chat participants in the current text chat room. When a selected participant uses the received session information, and enter s the received participant code and a callback number, the Call Broker in cooperation with a Network Adjunct Processor (NAP) completes voice links to the initiator and the selected participant(s). The need for each party to have a second subscriber line is advantageously avoided by having the Call Broker arrange to have one or more voice links completed through a VoIP link, and further reduces the need for second lines for participants by forwarding a Call Broker - placed call to a busy participant line to the participant's Internet Service Provider (ISP), which then sends a message to the participa nt announcing one or more options for receiving the incoming call, including receiving the incoming call through a VoIP link.
Patent CA-2310545-C (CA)
Title: Wireless communications using circuit-oriented and packet-oriented frame selection/distribution functions
Inventor: RUBIN HARVEY
IPC: H04W16/02
Filed: 2000-06-02
Granted: 2005-02-22
Abstract: In a wireless communications system having a centralized interworking function (IWF) and geographically distributed base stations, a packet-oriented frame selection/distribution (FSD) function forwards forward-link user data intended for a particular mobile unit directly to a primary base station, which determines whether to transmit the forward user data to the mobile unit using a fundamental channel or a supplemental channel. If the data is to be transmitted using a fundamental channel, when the base station is operating in soft handoff, the forward user data is transmitted from the primary base station back to a circuit-oriented FSD  function for forwarding to all of the base stations currently participating in the soft handoff, so that all of the base stations can transmit the forward-link user data to the mobile unit at the same time. If the data is to be transmitted using a supplemental channel, then the primary base station is able to assign a supplemental channel and transmit the forward user data to the mobile unit using the supplemental channel in simplex mode, independent of whether or not the mobile unit is otherwise operating in soft handoff. In this way, forward-link data transmissions can be performed without first having to coordinate either the timing or the data rate with any other base stations or with the FSD function. As such, the reactivation time needed to resume active forward-link data transmissions using a supplemental channel from the control hold state is less than the corresponding reactivation time under the prior art, which does require coordination of timing and data rate between all base stations in soft handoff.

Title: Apparatus method and system for maintaining call control at a gateway mobile switching center utilizing a packet network
Inventor: HUDEPOHL THOMAS EDWARD
IPC: H04M3/00
Filed: 2001-02-28
Granted: 2005-04-26
Abstract: The apparatus, method and system embodiments of the present invention provide for maintaining call control at a gateway mobile switching center (MSC), for roaming mobile units, utilizing a packet network or link, such as an ATM link.  The preferred system embodiment includes a gateway MSC, a serving MSC, and a base station having a wireless link with the roaming mobile unit. The gateway MSC includes a protocol handler for voice (PHV). For any given incoming call for the roaming mobile unit or outgoing call from the roaming mobile unit, the gateway MSC designates a specific address (or channel) on the PHV, referred to as a data link connection identifier (DLCI), for use as an address for voice packets to be received from the roaming mobile unit via the base station and serving MSC, and the base station also provides a base station packet address to the gateway MSC, for use as an address for voice packets to be received from the gateway MSC (through the serving MSC) for the roaming mobile unit, thereby creating a full duplex packet link. The packet link serves as a voice path between the base station, the serving MSC, and gateway MSC, with all communication to and from the roaming mobile unit routed through the gateway MSC. The gateway MSC thereby maintains all call control for the roaming mobile unit for the implementation of advanced calling features, such as call waiting and three-way calling. In the preferred embodiment, the DLCI is included as a new parameter for ANSI-41 compatible messages. In addition, new ANSI-41 compatible messages are also utilized, a Gateway Origination Request containing the base station packet address and a Gateway Origination Request Return Result containing the new DLCI parameter.
