Patent CA-2189605-C (CA)
Inventor: BOSSI BURT JOSEPH
IPC: H04M1/00
Filed: 1996-11-05
Granted: 2001-01-16
Abstract: A telephone adjunct interface for use with a network-based voice and/or data message storage and delivery service detects and alerts the subscriber to the existence of waiting messages. The interface device utilizes a combination of AC ring detection and outclass polling of the network to determine whether a visual and/or audible notification should be provided to the subscriber. That is, if the subscriber phone is not answered after a selected number of rings, the interface polls the network after a suitable delay to determine if any messages were left. If the subscriber line is busy or on call-forward while a calling party is seeking to leave a message, the network service platform stores the message and waits a selected interval before seeking to alert the subscriber. Advantageously, the device is configured as a small, portable and inexpensive consumer. premise unit which connects easily to all standard analog telephone systems that use modular connectors.

Title: Fluorescence polarization detection of nucleic acids
Inventor: LINN CARL PRESTON
IPC: C12Q1/68
Filed: 1996-11-08
Granted: 2000-02-15
Abstract: The present invention provides methods for detecting amplified oro unamplified nucleic acid target sequences at increased temperatures by changes in fluorescence polarization. The decrease in fluorescence polarization associated with hybridization of oligonucleotides at higher, more stringent, temperatures is overcome by including a double-stranded DNA binding protein in the assay. At elevated temperatures, the double-stranded DNA binding protein restores, and often enhances, the magnitude of the change in fluorescence polarization associated with single- to double-stranded conversion of an oligonucleotide probe or primer.

Abstract: A control system for a single-valve controlled medical ventilator adaptively invokes separate flow delivery or flow exhaust control functions in response to the sensed dynamic state of the ventilator without any dependence on measured patient parameters. The control system selects either the flow delivery control system or flow exhaust control system based on a determination of the mode in which the ventilator is operating. The determination is made using a sensed ventilator operational parameter, such as the ratio of manifold pressure to flow output, to select the appropriate control function. A hysteresis routine is provided to prevent "hair triggering"  between the flow delivery and flow exhaust control systems.

Abstract: A lock mechanism has at least one tumbler pin having one or more slots in the tip surface of the pin and a key blade which is formed with a projection extending from the surface of the bitting area. The tumbler pin can be rotatable in such a manner that it will seek to accommodate the projection on the surface of the key and to match the surfaces of the key and tumbler pin tip, thus aligning the tumbler pin at a position predetermined by the key bitting. In this regard, the tumbler pin tip is preferably tapered and adapted to engage with a key having a complementarily shaped bitting surface, i.e., complementary to the tapered surface of the tumbler pin tip, such that the tumbler pin will seek to accommodate the tapered surface of the key bitting to align the tumbler pin at a proper position. Alternatively, the tumbler pin can include a projection or the like to inhibit rotation of the tumbler pin. Cylinders and keys according to the present invention can be arranged in hierarchical systems to perform special functions and provide master keying capability.

Abstract: A nozzle or tube (1) is useful for pouring molten metal, especially alumin um killed molten steel. The nozzle (1) is formed from a blend of doloma and graphite which is bonded together in a carbonized matrix. Nozzles or tubes (1) made i n accordance with this invention have enhanced thermal shock resistance. Furthermore, nozzles or tubes (1) of this invention resist the formation of aluminum oxid e therein when they are used for pouring aluminum killed steel. Consequently, these tubes or nozzles (1) can be used in a continuous casting process for a long period of time without having to periodically stop the procedure and change the tubes (1) a s they become blocked with aluminum oxide. As a result of the thermal shock resistance, the usual preheating step prior to contacting the nozzle (1) with the molten metal is greatly reduced.

Abstract: A computer system with a speech recognition component provides a method and apparatus for instructing and evaluating the proficiency of human users in skills that can be exhibited through speaking. The computer system tracks linguistic, indexical and paralinguistic characteristics of the spoken input of users, and implements games, data access, instructional systems, and tests. The computer system combines characteristics of the spoken input automatically to select appropriate material and present it in a manner suitable for the user. In one embodiment, the computer system measures the response latency and speaking rate of the user and presents its next spoken display at an appropriate speaking rate. In other embodiments, the computer system identifies the gender and native language of the user, and combines that information with the relative accuracy of the linguistic content of the user's utterance to select and display material that may be easier or more challenging for speakers with these characteristics.

Abstract: A process for converting in a single pass an aqueous alkaline pH, alkali metal chlorite solution into an aqueous chlorine dioxide-containing solution that involves the combination of (1) using an electrochemical acidification cell to lower the pH value of the aqueous alkali metal chlorite feed before it enters the anode compartment of an electrochemical oxidation cell where the chlorite is converted to chlorine dioxide with (2) using an anolyte flow pattern where the anolyte passes through a porous, high surface area electrode. This process results in a substantially improved conversion efficiency per pass.
