Patent AU-554562-B2 (AU)
Title: Distillation process and apparatus
Inventor: GORE WILBERT LEE
IPC: B01D3/14
Filed: 1983-03-04
Granted: 1986-08-28
Abstract: A membrane distillation module is provided with a thin, flexible microporous P.T.F.E. membrane (16) positioned against an impermeable condensor sheet (12) that is stiffer in bending than the membrane. Distillate vapour diffuses through the membrane from a hot feed flowing rapidly past the membrane, and condenses and collects between, and in intimate contact with, the membrane and the condensor sheet. The condensed distillate is stripped by forces exerted by the hot feed acting on the distillate across the membrane, and flows toward a distillate outlet (40) located in the downstream direction of the hot feed flow. Cold feed flows past the condensor sheet in the counter direction to that of the hot feed.

Title: Position sensor and circuit for optical encoder
Inventor: MORTARA ALESSANDRO
IPC: G06K7/10
Filed: 1999-11-17
Granted: 2002-08-08
Abstract: An electronic circuit for measuring the position of a spatially periodic intensity pattern of incident radiation includes an array of detectors (1); two or more correlator units (2, 3) each having arrays of capacitors (12, 13) connected to a buffer (14); and a phase angle computing unit (4). The pitch of the array of detectors (1) is smaller than the pitch of the incident intensity pattern so that the latter is oversampled, yielding high accuracy. The detector outputs (17) are weighted by respective fixed capacitance values (15, 16) which vary periodically along arrays of capacitors (12, 13), and a weighted sum of outputs for each correlator unit (2, 3) is output at its respective buffer (14). The capacitance values (15, 16) of respective correlator units (2, 3) are mutually offset by a predetermined phase shift. The analog computation using capacitor arrays (12, 13) is fast and energy efficient, and can be implemented as a VLSI circuit.

Title: Improved low voltage programmable compressor
Inventor: WALDHAUER FRED DONALD
IPC: H04R25/04
Filed: 1989-02-23
Granted: 1991-09-05
Abstract: A programmable low voltage compressor circuit suitable for use with hearing aids is described. The compressor has a continuously variable compression ratio wherein the gain of the compressor may be programmably controlled over a wide range and the compressor may be powered from a power source as low as 1.1 volt. The compressor employs a variolosser wherein the gain is controlled by the ratio of the currents flowing out of first and second control terminals. A control circuit coupled to the variolosser controls the magnitude of the currents flowing out of the two control terminals. The control circuit includes a peak detector which generates a signal related to the peak positive envelope of the signal input to the compressor. A voltage to current converter is coupled to the peak detector for increasing the magnitude of the current flowing out of one of the control terminals of the variolosser as the voltage output of the peak detector increases. Furthermore, the gain and compression ratio of the compressor over a wide range is programmably controllable.

Title: System bus preempt for 80386 when running in an 80386/82385 microcomputer system with arbitration
Inventor: BLAND PATRICK MAURICE
IPC: G06F9/44
Filed: 1989-05-05
Granted: 1991-06-06
Abstract: A multi-bus microcomputer system includes a cache subsystem and an arbitration supervisor. A CPU is provided with a PREEMPT signal source which generates a preempt signal in CPU cycles extending beyond a specified duration. The preempt signal is effective at any device having access to the bus to initiate an orderly termination of the bus usage. When that device signals its termination of bus usage, the arbitration supervisor changes the state of an ARB/GRANT conductor, which had been in the grant phase, to the arbitration phase. During the arbitration phase each of the devices (other than the CPU) cooperates in an arbitration mechanism for bus usage during the next grant phase. On the other hand, the CPU, having asserted preempt, responds to a signal indicating initiation of the arbitration phase by immediately accessing the system bus.
