Title: Echo trap
IPC: H04B3/20
Filed: 1975-07-10
Abstract: 1510162 Echo suppressors SIEMENS AG 27 June 1975 [24 July 1974] 27285/75 Heading H4R In an echo suppressor provided on the four wire side of a hybrid junction a normally transmissive blocking device 3, Fig. 6, is provided in the transmit path together with an attenuation element 4 in the receive path, with a switch 41 which is normally in a position to by-pass the attenuation element. A control circuit detects a signal in the receive path and, in the absence of signal in the transmit path, causes the blocking element 3 to block the transmit path. When a signal is detected in both paths operation of blocking element 3 is inhibited but the switch 41 is operated to insert the attenuation element, but is arranged so that as the signal in the transmit path increases relative the signal in the receive path the attenuation of the attenuation element is reduced and/or the switch 41 is allowed to revert and by-pass the attenuation element. As described the signal in the transmit and receive paths can be compared in comparator 8 and the output caused to increase the attenuation 43 in the control path of a compressor 42, 43, 4, or, Fig. 2 (not shown) the output of comparator 8 can be used to inhibit the operation of AND gate (47) controlling switch 41. Alternatively control of the attenuator 43 in the compressor 42, 43, 4, can be effected via a threshold device coupled either to the output of comparator 6, Fig. 4 (not shown) or the output of signal detector 62, detecting the signal in the transmit path, Fig. 5 (not shown). A further modification, Fig. 4, includes a variable gain amplifier 71 in the transmit path signal detector circuit and a variable attenuator 73 in the receive path signal detector circuit which are both controlled in accordance with signal level in the respective path via a storage control device 70 which is blocked by controller 60 during duplex operation. The arrangement varies the control sensitivity in accordance with the hybrid junction attenuation. A delay device 65 is provided in the receive path speech detector to compensate for the delay through the hybrid junction.

Patent IL-94822-A (IL)
Title: Method and apparatus for determining the characteristics of a fluid having a biological analyte.
IPC: G01N21/35
Filed: 1990-06-21
Abstract: The characteristics of a biological fluid sample having an analyte are determined from a model constructed from plural known biological fluid samples. The model is a function of the concentration of materials in the known fluid samples as a function of absorption of wideband infrared energy. The wideband infrared energy is coupled to the analyte containing sample so there is differential absorption of the infrared energy as a function of the wavelength of the wideband infrared energy incident on the analyte containing sample. The differential absorption causes intensity variations of the infrared energy incident on the analyte containing sample as a function of sample wavelength of the energy, and concentration of the unknown analyte is determined from the thus-derived intensity variations of the infrared energy as a function of wavelength from the model absorption versus wavelength function.

IPC: H03K17/60
Filed: 1984-01-25
Abstract: PURPOSE:To improve remarkably the characteristic of a digital circuit by utilizing a reverse current of a Schottky barrier diode to drive a transistor (TR) momentarily. CONSTITUTION:In the transient state that the logical state of a digital input voltage Vin is changed from ''L'' to ''H'', the logic circuit consists of the Schottky barrier diode D1 reverse-biased by the digital input voltage Vib and a TRQ1 driven momentarily by a reverse current Irl flowing to the Schottky barrier diode when the diode D1 is reverse-biased. The transient state of the digital circuit is controlled by the momentary conductive operation of the TRQ1. The mechanism of flowing of the reverse current is that the diode D1 and a TRQ7 are turned on with the Vin set at low level and a positive electric charge Q is charged to an electrode at the Y side of the capacitor comprising a barrier capacitance iSBD and a parasitic capacitance.
