Patent EP-0339771-A3 (EP)
IPC: H01L21/311
Filed: 1989-03-01
Abstract: MOVPE growth and photoetching are integrated into a 
unified sequence which is carried out without removing a 
workpiece from a MOVPE reactor. Growth may be carried out 
before, after or before and after the etching.  
     To prevent pattern broadening by diffussion of the 
active species the substrate is preferably protected by a 
fugitive coating which is removed by the illumination. Native 
oxide coatings are particularly suitable for InGaAsP 
substrates. These are conveniently applied by exposing to 
substrate to 20% 0₂ + 80%N₂ for about 3 minutes 
at 450°C.

period of time; a RAM for storing the document 
size/orientation data; and control means for (i) 
controlling the timer to start its measuring operation 
upon detection of a document size/orientation by the 
document size detection device, (ii) controlling the 
driving motor to move the rotating section of the 
rotatable cassette to either of the longitudinal and 
lateral feed positions which corresponds to a determined 
orientation of the copy paper if the copy material 
orientation changing means is selected by the automatic 
paper selection function, and there occurs no change in 
 
 
the document size/orientation data sent from the document 
size detection device to the RAM before the completion of 
the measuring operation by the timer, and renewing the 
document size/orientation data stored in the RAM and 
restarting the measuring operation of the timer if the 
document size/orientation data have been changed before 
the completion of the first set measuring operation of the 
timer. With the above arrangement, even if there occurs a 
change in the document size/orientation data due to a 
detection error etc. within a predetermined time period, 
the rotating section of the rotatable cassette can be set 
in a desired feed position without undesirable rotations.

Title: Microphone-controller with multifunction single conductor
IPC: H04M1/60
Filed: 1990-12-20
Abstract: The single power conductor carries audio and a serial data bus. The microphone's amplifier (101) is connected to the conductor (108). The incoming audio signal rides on the DC supply voltage from the radiotelephone. The supply voltage, through a voltage regulator (103), supplies power to the amplifier (102) and a microprocessor (105), used to transmit the serial data message on the conductor (108). Both the amplifier (102) and the voltage regulator (103) are isolated from the power conductor (108) by a FET switch (104) that is controlled by the microprocessor (105). The switch (104) is turned off, isolating the circuitry when the microprocessor (105) is transmitting. <IMAGE>

Title: Variable origin - variable angle acoustic scanning method and apparatus
IPC: H04R17/00
Filed: 1991-02-12
Abstract: An acoustic scanning method and apparatus implemented by transmitting ultrasonic pressure waves and receiving return echoes on a set of spatially non-overlapping acoustic lines scanned along a transducer array (6) with the active acoustic lines shifted and steered so that each acoustic line originates at an arbitrary point (4a-4d) on and at an arbitrary angle to the face of the array. In a preferred embodiment, an extension of each acoustic line may also pass through a substantially common vertex (4a-4d) that is not on the face of the transducer array (6), but preferably behind it a selectable distance to provide an extended field of view. The extended field-of-view is defined by the selectively variable location of the common vertex (4a-4d) of the acoustic lines and the physical ends of the array, may use the entire transducer array in the near-field, has high quality resolution in both near and far fields, and may simultaneously transmit and receive two or more ultrasound beams from the same transducer aperture. <IMAGE>

Title: Device for the remote control of a shower
IPC: E03C1/05
Filed: 1992-02-16
Abstract: A device for the remote control of a shower comprises a first sensor (3) having a first detection region (5). If a user enters this detection region (5) a detection circuit (7) which is connected downstream of the sensor (3) ensures that the magnetic valve (9) which controls the water flow through the showerhead (1) is opened. A second sensor (4) is also provided which has a considerably smaller detection region (6). If the user who is standing under the shower (1) moves his hand into the smaller detection region (6) of the second sensor (4), a detection circuit (10) which is arranged downstream of said sensor likewise generates an output signal. The output signals of the two detection circuits (7, 10) are combined via a circuit (11) which carries out a logic AND function and produces an output signal when both the sensor (3) having the larger detection region (5) and the sensor (4) having the smaller detection region (6) respond. This output signal is now in turn supplied to a logic circuit (12) which, at the start of this signal, determines the respective switching state of the electrically operated valve (9), like a changeover switch, and moves it to the opposite state, that is to say for example closes an open valve or opens a closed valve. <IMAGE>

Patent EP-0550088-A3 (EP)
Inventor: PENNA DAVID EDWARD
IPC: G09G5/36
Filed: 1992-12-14
Abstract: A microprocessor (MPU) is programmed to process pixel values of an input image to generate an output image, by means of systematic selection and combination of input pixel values. The system for selection and combination depends on a variable parameter (for example a zoom factor). Means responsive to the parameter value compiles (401) a machine code subroutine which is specific to that parameter and will cause the generation of one row of output pixel values. This compiled filter is then executed repeatedly (408) to generate all rows of the output image. The arrangement substantially eliminates per-pixel decisions, and is consequently faster than conventional microprocessor arrangements. <IMAGE>

Title: Electronic apparatus with ultrasonic motor
IPC: H02N2/16
Filed: 1993-03-23
Abstract: An electronic apparatus which is equipped with an ultrasonic motor (221, 
222, 223) and which consumes only a small amount of electric power, is stable in 
performance, and is capable of accurately controlling the angular position is 
described.  
     An environment detection means (231) detects the environment such as the 
rotation of the moving member (222) of the motor, the voltage of the power supply 
(201) or the temperature. Driving pulses corresponding to the environment are 
stored in a driving pulse storage circuit (205). Similarly stopping pulses may be 
stored in a stopping pulse storage circuit (210). An output pulse selecting circuit 
(207) provides output pulses to drive the ultrasonic motor in dependence upon the 
detected environment by selecting the appropriate driving pulses or possibly 
stopping pulses.

IPC: H04M1/00
Filed: 1994-12-09
Abstract: An automated method for modifying a speech signal communicated
over a telephone network applies a gain factor (in 25) in a telephone set before any
side tone is added thereto. The gain factor is a function (24) of a received signal
indicative of the background noise (22) at the location of the telephone set. The gain
applied may be a function of both the background noise level (22) and the original
speech signal (23). Either a linear or a non-linear (e.g., compressed) amplification of
the original speech signal may be performed, where a compressed amplification
results in the higher level portions of the speech signal being amplified by a smaller
gain factor than lower level portions. The speech signal may be separated into a
plurality of subbands, each resultant subband signal being individually modified in
accordance with the present invention. In this case, each subband speech signal is
amplified by a gain factor based on a corresponding subband noise signal, generated
by separating the background noise signal into a corresponding plurality of
subbands. The individual modified subband signals may then be combined to form
the resultant modified speech signal.
