Title: Systems and methods for loop length and bridged tap length determination of a transmission line
Inventor: BELGE MURAT
IPC: H04L1/00
Filed: 2001-01-08
Granted: 2010-03-23
Abstract: Through the use of a least squares minimization concept, the loop length, the number of bridged taps and length of the bridged taps on a transmission line can be determined from readily available modem data. In particular, the loop length, the number of bridge taps and the length of bridged taps can be estimated by comparing a measured fequency domain channel impulse response of the transmission line to a model of a loop that is comprised of multiple sections and multiple bridge taps.

Title: Method and device for reading authentication means and adapted identification means
Inventor: BOURRIERES FRANCIS
IPC: G06T1/00
Filed: 2001-02-02
Granted: 2009-06-30
Abstract: The invention concerns a method for reading single volume and non-reproducible identification means (100) comprising a mixture of at least two materials (110 and 120) distinguishable from each other (110 and 120), characterised in that it consists in recognising in two dimensions the internal heterogeneous structure of said identification means (100) and in isolating and demonstrating its third dimension thereby eliminating the risk of imposture. Said characteristic enables to reduce storage volume and the periods of time required for scanning, acquisition and comparison operations performed in such processes. The invention also concerns a device for implementing said method. The invention is useful for identifying and authenticating objects, living beings, transactions.

Abstract: In a closed-loop process, a controller uses a flow sensor to monitor the flo w of a medicinal fluid being infused into a patient, to achieve a desired rate of flow. A relatively inexpensive peristaltic pump or electronically controlled valve can be used to vary the flow of the medicinal fluid through a fluid line. A Y site within the fluid line includes an integral flow sensor having an orifice. The flow sensor includes proximal and distal pressure sensors disposed on opposite sides of the orifice to monitor the distal and proximal pressure, producing a signal indicative of the rate of flow of the medicinal fluid through the fluid line. A signal produced by the controller is input to a motor driving the pump or to the valve to vary the rate of flow a s required to achieve the desired infusion rate of the medicinal fluid.</SDOAB >
