Title: Telephone instrument with echo-cancellation device
Inventor: CHRISTIAN FREUND
IPC: H04M9/08
Filed: 1991-06-27
Abstract: The invention relates to a telephone instrument with an echo-cancellation device in which a finite impulse response auto-adaptive transverse digital filter (FIR) has one input linked to one reception channel, an adder is inserted into a sending (transmission) channel, and one output of the filter (FIR) is linked to one output of the adder so that it delivers a signal which is the algebraic sum of the signal originating from the filter (FIR) and of that originating from the microphone (M). Two receiving channels (Bh, B1) and two sending channels (Bh, B1) are provided respectively for low and high subbands; the channel to which an input of the filter (FIR) is linked is a low channel (B1); the channel in which the adder is inserted is also a low channel (B1); in the two high channels (Bh) gain switches (ARh, ATh) are inserted. The invention is particularly suitable for hand-free instruments working in wide bands.

Title: Method and device for calibrating an optical pyrometer, and associated reference wafers
Inventor: DILHAC JEAN-MARIE
IPC: G01J5/02
Filed: 1992-05-04
Abstract: The method involves detecting at an instant t a discontinuity in reflection from a layer of active material having reflection discontinuity at a known temperature in order to determine the temperature which should be shown by a temperature measuring means (pyrometer (14)) at this instant t. The device according to the invention sends an electromagnetic wave (11) to the active material and senses (12), measures and analyses (32, 31, 33) the intensity of radiation reflected by this material in order to determine the discontinuity involved. The reference wafers (18) advantageously consist of a thin layer of active material deposited on a thin separating layer, itself deposited on a thin layer substrate. The active material layer is additionally covered by a protective layer. A pyrometer (14) used in ovens (15) for rapid heat treatment of semiconductor wafers (18) can be calibrated in this way.

Title: Machining by controlled high-pressure fluid jet
Inventor: PATRICK LE TESTU
IPC: B24C7/00
Filed: 1992-12-29
Abstract: A head chamber (3) is supplied (2) with fluid, e.g. water, under high pressure, and, optionally abrasives. The cutting jet (6), expelled through a calibrated nozzle (4,5), impinges on the work (9). Sensors on the machine body (10), preceding (101) and trailing (102) the traversing jet, continuously monitor the work thickness and a head sensor (103) detects jet behaviour and reaction. In the processor (100), this information and that input to a memory (110) during calibration produce an output signal (108). The controller (104) responds, if necessary, by modifying the jet parameters e.g. speed is reduced over thicker sections. The head sensor (103), in soil excavation, allows buried services to be detected and avoided. Actuators are provided for varying the inclination of the jet to the vertical.

Title: Method for automatically cutting a flexible sheet material
Inventor: BOUSQUET PHILIPPE
IPC: A41H43/00
Filed: 1994-01-31
Abstract: Cutting is performed by automatically controlling relative movement between a cutting blade and a material along a desired cutting line according to set tangential speed and acceleration values for each line. On reaching an angle between a first cutting line path and a second path, the blade is rotated as it moves through the material so that it switches automatically from a first direction tangential to the first path, to a second direction tangential to the second path. Blade rotation takes place at a predetermined average rotation speed over a rotational path consisting of a predetermined portion of the first path and/or the second path which ends or begins at the apex of the angle or includes said apex. The average speed of the blade moving along the rotational path is correlated to the average blade rotation speed and the angle value, whereas the cutting blade moves along the first path and/or the second path, when outside the rotational path, at a set tangential cutting acceleration and speed determined for said path(s).

Title: Structure transformable into rigid beam
Inventor: SERGE BRINGOLF
IPC: E04C3/00
Filed: 1994-04-21
Abstract: The transformable structure comprises two supple components which after assembly assumes the shape of a rigid beam. There are two link chains (1,2) whose links (3,4) are pivoted about their respective axes (7,8) and have opposing support points (10,11).
