Title: Enhanced acoustic calibration procedure for a voice switched speakerphone
Inventor: ERVING RICHARD HENRY
IPC: H04M1/60
Filed: 1991-11-22
Abstract: An acoustic calibration circuit (210, 213, 220, 230), in a voice switched adaptive speakerphone (200) accurately determines the type of acoustic environment of both large and small rooms having either harsh or favourable acoustics. The calibration circuit determines the acoustic environment of a room by emitting a tone burst through a loudspeaker (212) associated with the speakerphone and generating an echo decay parameter that is indicative of the duration of echoes from the tone burst signal measured with a microphone (211) also associated with the speakerphone. The echo decay parameter is generated from a composite representation of the acoustic response for those echoes having the largest returned amplitude level measured at each one of multiple predetermined time intervals by the calibration circuit. By examining the amplitude levels in the composite representation at selected ones of the multiple predetermined time intervals, the echo decay parameter or estimate for the additional time required for the echoes to dissipate to a desired level is generated. If after performing a first measurement of the room acoustics at a prescribed first time period, the calibration circuit determines that the room echoes have not dissipated to an acceptable level in this first time period for generating a satisfactory echo decay parameter representative of these echoes, the calibration circuit regenerates the tone burst into the room a second time and then measures the resulting level of the acoustic response over an extended time period. This information is then used by the speakerphone in adapting its operating parameters. <IMAGE>

Patent GB-944087-A (GB)
Abstract: 944,087. Loud-speaking telephones. TELEFONAKTIEBOLAGET L. M. ERICSSON. June 8, 1962 [June 8, 1961], No. 22388/62. Headings H4K and H4R. In a loud-speaking telephone substation employing separate amplifiers F1, F2 for outgoing and incoming speech signals each associated with one of two current controlled attenuation circuits D1, D2 which are normally attenuating, third and fourth current controlled attenuation circuits D3, D4, controlling outgoing and incoming speech signals respectively, are provided, these being normally only slightly attenuating. A control current supply circuit R13, R14, R15, R16, R17, C3, C4 has two terminals 1, 2 between which are connected in series the control circuit of the first attenuation circuit, the parallel combination of the control circuits of the third and fourth attenuation circuits, and the control circuit of the second attenuation circuit. Two control amplifiers Tr1, Tr2 control the supply circuit, the former fed with speech signals from before the first attenuation circuit D1 and the latter with speed signals from before the second attenuation circuit D2, the outputs of the two control amplifiers being connected to the terminals 1, 2 so that in operation the direction of the control current of D1 and D3 is the same and is opposite to that of D2 and D4. Operation.-In the rest condition Tr1 and Tr2 pass equally large direct currents e.g. 1 mA. each so that the potentials at 1 and 2 are the same, and Equal control currents flow in D1 and D2 (see Fig. 3), while zero control currents in D3 and D4 since R14 and R17 are equal and R15 and R16 are equal. Outgoing speech from the microphone M then cause the centre tap of T3 to go negative with respect to the point 5. This negative potential is applied via the secondary winding of T2 to the base of Tr2, and the increased positive potential of the point 5 is transmitted to the base of Tr1 via the secondary windings of T4 and T1. The resulting increased current passed by Tr2 gives an increased potential drop in R11 common to the two transistors, whereas the current passed by Tr1 decreases. Terminal 2 is thus at a higher potential than terminal 1 so that D2 and D4 are fed with control current and the control current of D2 falls to zero. Outgoing speech currents thus pass to line, but incoming speech currents cannot reach the loud-speaker H. The occurrence of incoming speech currents in the rest condition have the opposite effect. Specification 944,088 is referred to.

Title: Checking the operability of a vehicle fuel tank venting system
Inventor: PFLEGER HARTMUT
IPC: F02M37/00
Filed: 1995-08-04
Abstract: A method for checking the operability of a vehicle fuel tank venting system to identify leaks above about 1 mm is aborted if successive values of the pressure of the system taken by a pressure sensor 13 change faster than a predetermined rate making it impossible to make a clear statement about the operability of the venting system, e.g. as may occur if a car door is slammed or a vehicle which is rolling slowly is braked hard. The pressure of the system is monitored throughout the course of the method, preferably the mean value of two successive pressure values is formed and if the difference between the mean value and the current pressure lies outside a preselected dynamic range the method is aborted. The pressure sensor 13 may be connected to venting line 12 running between the fuel tank 10 and the filler neck 11 or may be inserted at any point within the tank venting system. The system comprises a vent line 14 connecting the tank to an activated carbon container 15 having a shut off valve 24, a regeneration line 18 between the container 15 and a throttle valve 19 at the intake of the engine, and an electronic control device 28, the line 18 including a deaeration valve 22. The method preferably involves, by means of opening and closing the deaeration valve and the shut-off valve and taking and comparing pressure readings, checking operational variables relating to the engine and the system (such as vehicle speed, engine coolant temperature, faults in the deaeration valve, lambda controller, throttle valve, pressure sensor or shut off valve) and the method is terminated if preselected values of the operational variables, at which it is possible for a reliable statement to be made about the operability, are not attainable. The control device 28 communicates an ascertained fault acoustically or visually to the driver. <IMAGE>
