Patent number: 10585644Abstract: An integrated quantum random noise source includes a substrate, an optical oscillator that may be integral to the substrate coupled by an optical waveguide to an optical directional coupler. The optical directional coupler has two outputs that are coupled by optical waveguides to a pair of photodetectors that are part of a balanced photodetector. The balanced photodetector in response outputs an analogue signal proportional to the difference in photocurrents of the two photodetectors. The analogue output signal from the balanced photodetector is a random Gaussian-distributed signal representative of quadrature measurements on the quantum vacuum state of light. The random noise source can be coupled other apparatus to provide a source of random bits.Type: GrantFiled: April 11, 2018Date of Patent: March 10, 2020Assignee: QuintessenceLabs Pty Ltd.Inventors: Ken Li Chong, Andrew Lance

Patent number: 8920615Abstract: A salt water chlorinator (30) for a swimming pool includes an electrolysis cell having two anodes (98) and a cathode (94). Two scrapers (102), each of which is of titanium and includes scraping portions in the form of ribs (106) in contact with the opposite surfaces of the cathode, are reciprocated relative to the cathode (94) to remove scale deposits from the cathode (94). The scrapers (102) are mounted in a frame (110) and their scraping ribs (106) are curved such that the ribs (106) are self-biased against the cathode surfaces. A mechanism for reciprocating the scrapers (102) includes two solenoid coils (116) which act on cores (114) in a stem (112) of the frame (110). A control circuit for the electrolysis cell is contained in a housing (86) which is attached to a housing (82) for the electrolysis cell. The control circuit includes a flow sensor for sensing salt-water flow through the electrolysis cell.Type: GrantFiled: September 16, 2010Date of Patent: December 30, 2014Assignee: Davey Water Products Pty LtdInventors: Robert Bruce Davidson, Mark Andrew Lance
