Patent CA-2336695-C (CA)
Title: Refractory and temperature-resistant composite material "refsic"
Inventor: GNESIN BORIS ABRAMOVICH
IPC: C22C49/14
Filed: 1999-07-05
Granted: 2008-07-15
Abstract: The present invention pertains to the production of materials used in high- temperature oxidising media, wherein said materials can be used in the production of high-temperature electric heaters as well as in the production of parts, sensors and instruments operating at temperatures of 1900 ~C and above. These materials, which essentially contain tungsten and molybdenum silicides MeSi2-Me5Si3 as well as silicon carbide, are characterised in that they exhibit high levels of heat-resistance, of resistance to thermal shocks, of high-temperature strength and of wear resistance. Doping with rhenium, tantalum, titanium, zirconium, niobium and hafnium silicides increases the mechanical properties of these materials. These materials, which have a desired porosity, can be used for increasing the specific electric resistance and for reducing thermal conductivity relative to high-density materials, while having a reduced density.

Title: Transmitting and receiving device and method for continuous outer-loop power control while in dtx mode in a cdma mobile communication system
Inventor: YUN YU-SUK
IPC: H04B7/005
Filed: 2000-05-29
Granted: 2007-06-26
Abstract: A device and method for continuous outer-loop power control on a physical channel which transmits only power control bits and no data while in discontinuous transmission (DTX) mode in a CDMA mobile communication system is disclosed.  In the power controlling device according to one aspect of the present invention, a frame error detector detects an error from a frame of predetermined length and generates an error signal indicating whether an error has been generated. A closed-loop power controller compares a threshold with the signal-to-noise ratio (SNR) in each power control group (PCG) in a plurality of periods of the frame and generates power control information according to the comparison result. An outer-loop power controller increases the threshold in order to generate power control information that commands a power increase in response to an error signal indicating the existence of a frame error, and decreases the threshold in order to generate power control information that commands a power decrease in response to an error signal indicating the absence of a frame error. An offset controlling unit, which is connected to the outer-loop power controller, receives gating information about the gated transmission of data in a frame at a predetermined rate, and generates an offset signal, which indicates an offset corresponding to a changed gating rate if the gating rate is changed.

Filed: 2000-12-18
Granted: 2008-10-14
Abstract: A method is described for determining recirculation of blood in a vascular access (11) of a patient undergoing dialysis treatment by means of a dialysis machine (10) comprising an arterial line (24) for withdrawing blood from the patient's body, a dialysis filter (16), and a venous line (26) for returning the blood to the patient's body. The present method consists in inducing, in the blood flowing in the venous line (26), a disturbance of a magnitude such as to bring the system into a transient state and determining blood recirculation in the vascular access (11) during the transient state as a function of the magnitude of the disturbance induced in the arterial line (24). In particular, the aforesaid disturbance consists of the variation of the haemoglobin concentration in the blood flowing in the venous line (26) and the variation is caused by controlling a change in the ultrafiltration flow in dialysis filter (16).

Abstract: An optical fiber distribution module achieves high density of connections on one board, yet prevents fiber cord tangling created by repeated connection/disconnection of cords. The module has a connection board with an array of optical connector adaptors for connecting in-use optical fiber cords, and a storage section for storing not-in use optical fiber cords, where a plurality of cord sorting boards having a plurality of fiber cord passageways for accommodating and retaining at least one optical fiber cord is arranged between the connection board and the storage section. This design of the board enables to organize groups of cords into in-use cords and not-in-use cords. The load on the cords are supported properly so that fiber tangling and fiber distortion are prevented. Therefore, high density optical fiber can be achieved without introducing signal distortions.

Title: Message sender status monitor
Inventor: MILLEN DAVID R
IPC: H04L12/58
Filed: 2002-11-14
Granted: 2006-06-20
Abstract: A message sender status monitor is used to determine the communication status of the sender of an electronic message. In the case of email, upon the recipient opening an email, a query is launched to a "status registry" to determine if the sender of the email is currently logged in to the communication network, or if the sender is currently on the telephone, or currently using a cell phone, etc. This status information is then used by the recipient of the email to determine the communication medium used to send a reply to the email sender. For example, if the status information indicates that the message sender is currently logged in to the data network, the recipient can respond using "instant messaging" (considered, therefore, to be a more efficient type of response that merely responding with an email message).

Abstract: A control system includes a transmitter and a receiver for receiving signals from the remote transmitter, and a multi-vehicle compatible controller cooperating with the transmitter and receiver. The multi-vehicle compatible controller preferably generates at least one set of command signals on the data communications bus for the at least one vehicle device. The at least one set of command signals may include at least one working command signal and at least one non-working command signal for a given vehicle to thereby provide compatibility with a plurality of different vehicles. Multiple signals or codes can be generated on the data communications bus, and only that code for the given vehicle will cause an operation or response from the vehicle device. Such an arrangement provides for a relatively simple and straightforward approach to interface with a vehicle having a data communications bus. The features are also readily implemented in an adaptor to use with conventional security or other control system controllers for vehicles
