Title: Coil winding machine
Inventor: DESJARLAIS MATTHEW G
IPC: B29C53/12
Filed: 2000-09-22
Abstract: A machine for forming helical coil from a heated elongate plastics material comprises an elongate cylindrical mandrel onto which the material is wrapped in helical formation which is rotatable about its longitudinal axis, a stationary helical guide coil wrapped around the mandrel and defining a helical guide path around the mandrel between turns of the guide coil into which path the material is guided for setting into a helical shape having a diameter determined by the diameter of the mandrel and a pitch determined by the pitch of the guide coil.  At least two drive rollers parallel to the axis of the mandrel which are rotatable each about a respective longitudinal axis for applying an outer driving force to an outside of the helical coil of plastics material while it is wrapped around the mandrel and while the mandrel applies an inner driving force to the inside of the helical coil of plastics material such that the inner and outer forces tend to drive the material helically along the mandrel from a supply to a discharge end of the mandrel. A  drive coupling member at one end of the mandrel for receiving a drive from a rotatable drive member. A mounting boss for supporting the mandrel so as to allow rotation of the mandrel while holding the mandrel against longitudinal movement, a coil support plate having one edge attached to the turns of the helical guide coil so as to support the helical guide coil along its length with the plate extending outwardly of the axis of the mandrel and a support member for supporting the coil support plate at positions along its length.

Patent CA-2322131-A1 (CA)
Inventor: DE JONGHE LUTGARD C
IPC: H01M6/14
Filed: 1999-02-17
Abstract: A method for forming lithium electrodes having protective layers involves plating lithium (16) between a lithium ion conductive protective layer (18) and a current collector (14) of an "electrode precursor". The electrode precursor is formed by depositing the protective layer on a very smooth surface of a current collector. The protective layer is a glass such as lithium phosphorus oxynitride and the current collector is a conductive sheet such as a copper sheet. During plating, lithium ions move through the protective layer and a lithium metal layer plates onto the surface of the current collector. The resulting structure is a protected lithium electrode. To facilitate uniform lithium plating, the electrode precursor may include a "wetting layer" which coats the current collector.

Inventor: CHOI YOUNG-HUN
IPC: C12N15/87
Filed: 1999-05-20
Abstract: A compound for polymeric targeted gene delivery carrier consisting of polyethylene glycol (PEG) grafted poly(L-lysine) (PLL) and a targeting moiety (TM), wherein at least one free amino function of the PLL is substituted with said PEG, at least one free amino function of the PLL is substituted with the TM, and the grafted PLL contains at least 50 % unsubstituted free amino function groups. TM is preferably lactose or galactose which are capable of specifically targeting a hepatoma cell or a liver cell. The new synthetic carriers with various substitution ratios of TM-PEG were characterized using NMR spectroscopy. The new polymeric gene carriers of this invention are capable of forming stable and soluble complexes with nucleic acids, which in turn are able to efficiently transform cells. PEG attached to the PLL gives better solubility properties to the gene/carrier complex and improved transfection efficiency without considerable cytotoxicity. Methods of preparing and using the TM-PEG-PLL as polymeric gene carriers to efficiently transfect cells are disclosed.

Title: Systems and methods for extracting switch data
Inventor: FOWLER LEONARD R
IPC: H04M15/00
Filed: 1999-05-21
Abstract: A system and method downloads data and reconfigures the data into a database . A telephone user purchases a specific number of lines and specific services (i.e., call waiting) from a telephone company. The telephony company then programs a switch associated with that user so that the user receives the services purchased. The telephone company also inserts the user's purchases into a database used for generating the user's bills. Discrepancies can occu r between the data in the switch and the data in the billing database. Billing  correction is performed by downloading all of the data within a switch, reconfiguring the data into a database and then comparing the switch databas e against the billing database to detect billing errors. To facilitate ease of  this billing correction process, the switch database is transmitted to the billing correction center via a network instead of the traditional method of  using direct tape copies of the switch being physically transported to the billing correction center.

Abstract: A method and system for providing configurable data services for mobile stations allows mobile stations to select the type and content of data messages addressed to a mobile station. The method includes establishing an active profile associated with a corresponding mobile station. A wireless data server receives a data message addressed to the mobile station. The active profile for the mobile station is accessed to determine applicable stored profile attributes for the mobile station to which the received data message is addressed. The wireless data server detects received profile attributes associated with the received data message. Filtering is applied to the received data message in real-time based on a comparison between the detected profile attributes and the stored profile attributes. The detected profile attributes are readily standardized in accordance with standards followed by the content service provider in order to gain access to the mobile service subscribers.

A motor is provided for rotating the container about an axis. A heater is provided for supplying heated air to the container during a dry cycle. A sensor is provided for providing a signal indicative of moisture content of the articles. Memory is provided memory for storing historical stop time data of respective dry cycles. A noise--reduction filter is coupled to receive the signal from the moisture sensor to provide selectable filtering to that signal. A timer provides a signal indicative of elapsed time upon start of the dry cycle. A module is responsive to the historical data in the memory for determining an initial estimate of the stop time of the dry cycle to be executed. A processor allows for estimating the stop time of the dry cycle as the cycle is being executed. The estimation of the stop time is based on a respective functional relationship of the noise-reduced sensor signal, and the timer signal, relative to one or more characteristics of the articles and one or more desired values of predetermined dry-cycle parameters selectable by a respective user of the dryer. The initial estimate of the stop time is superceded by the stop time estimated by the processor as the cycle is being executed.

Abstract: A system and method for providing fast and efficient conversation navigation via a hierarchical structure (structure skeleton) which fully describes functions and services supported by a dialog (conversational) system. In one aspect, a conversational system and method is provided to pre-load dialog menus and target addresses to their associated dialog managing procedures in order to handle multiple or complex modes, contexts or applications. For instance, a content server (web site) (106) can download a skeleton or tree structure (109) describing the content (page)(107) or service provided by the server (106) when the client (100) connects to the server (106). The skeleton is hidden (not spoken) to the user but the user can advance to a page of interest, or to a particular dialog service, by uttering a voice command which is recognized by the conversational system reacting appropriately (as per the user's command) using the information contained within the skeleton. The skeleton (109) provides the necessary information to allow a user to quickly browse through multiple pages, dialog components, or NLU dialog forms to find information of interest without having to follow and listen to every possible page or form leading to a desired service or conversational transaction.
