Title: Side tone preventive circuit for telephone
IPC: H04M1/58
Filed: 1989-11-29
Abstract: A side tone preventive circuit for telephones which 
prevents the output of the transmitter on the speaker's side 
from being transmitted to the receiver on the same side. 
The balance of the impedance bridge in a bridge circuit for 
separating a transmission signal and a reception signal is 
automatically adjusted in accordance with the circuit 
impedance at the location at which a telephone is installed. 
An impedance measuring circuit measures the impedance of the 
telephone circuit, and a balance adjustment circuit the 
impedance of which is adjustable is provided in the bridge 
circuit. The impedance of the telephone circuit is measured 
at the time of installation of a telephone, and the imped­
ance of the balance adjustment circuit is adjusted in 
correspondence with the result of measurement. Thus, the 
impedance balance of the bridge circuit is adjusted in 
correspondence with the circuit impedance, thereby effec­
tively preventing a side tone.

Title: Flow rate control system
IPC: G05D7/06
Filed: 1989-08-02
Abstract: A flow rate control system is disclosed for measurement of ink flow through an ink jet system. The flow rate control system receives an error signal indicative of deviation of flow rate from a set value. The system includes proportional (P), integral (I) and derivative (D) control to generate a control signal based on the magnitude and sign of the error signal. The control signal is used to control the on-time of an ink make-up valve which adds make-up ink to the system as ink is needed to maintain satisfactory operation. In a preferred embodiment, the PID controller has noise reduction capability through the use of clippers and low pass filters. In addition, conditional summation may be employed to minimize "hunting" at low error signal levels.

Patent EP-0367534-A3 (EP)
IPC: G02B27/01
Filed: 1989-10-30
Abstract: There is disclosed a helmet mountable display system 
which, in the stereoscopic version, includes separate 
optical paths for providing respective images to the left 
and right eyes of an observer for stereoscopic viewing, 
these paths sharing in common, however, a mechanical 
scanning arrangement. Each of a first and second plurality 
of spaced apart, substantially point light sources (14,15) 
supply a respective group of modulated rays of light. The 
rays of each group are collimated by a respective input 
lens (16,18) and the collimated rays from each input lens 
are directed so that their envelopes all intersect at the 
same point. A horizontal (27) and a vertical (25) deflect­
ing surface are disposed on opposite sides of the inter­
section point. Electro-mechanical drivers (26,24) move 
the surfaces which scan all the collimated rays. The 
scanned rays from each group are focused onto a respective 
screen (32,34) by a respective output lens (28,30) to form 
a raster scanned image. Preferably the screens are 
divided into a plurality of contiguous zones with a ray 
from each light source assigned to a corresponding zone, 
which reduces the vertical scan angle excursions required. 
Simultaneous scan lines from the rays are displayed in 
each zone on the screen which reduces the video bandwidth 
requirement of the system. The image from the screens 
(32,34) is supplied to the inside surface of a visor from 
which it is reflected to a corresponding eye of the 
observer.
