Publication number: 20230026900Abstract: A photoconductive transducer intended to generate or detect waves in the terahertz frequency domain or in the picosecond pulse domain is provided. The transducer comprises a three-dimensional structure that includes, in this order, a first planar electrode, an array of nano-columns embedded in a layer of resist and a second planar electrode parallel to the first planar electrode. The design of the transducer increases the optical-to-terahertz conversion efficiency by means of photonic and plasmonic resonances and by means of high and homogeneous electric fields. The height of the nano-columns as well as the thickness of the resist range between 100 nanometres and 400 nanometres. The width of the nano-columns is between 100 nanometres and 400 nanometres, the distance between two adjacent nano-columns is between 300 nanometres and 500 nanometres, the nano-columns are made of a III-V semiconductor.Type: ApplicationFiled: December 10, 2020Publication date: January 26, 2023Inventors: Christopher BAUERLE, Jean-François ROUX, Giorgos GEORGIOU

Patent number: 10972097Abstract: In accordance with an embodiment of the present invention, an optical switch includes a photoconductor body including a first edge and an opposite second edge, a first end and an opposite second end. The first edge is configured to receive an electrical input signal and the second edge is configured to deliver an electrical output signal. The photoconductor body is configured to have an electrically ON state that is activated by an optical signal and an electrically OFF state that is activated by an absence of the optical signal. A direction from the first end to the second end defines a longitudinal direction. The direction from the first edge to the second edge defines a first direction that is orthogonal to the longitudinal direction. A first dimension between the first edge and the second edge along the first direction decreases from the first end to the second end.Type: GrantFiled: August 29, 2017Date of Patent: April 6, 2021Assignee: STMICROELECTRONICS SAInventors: Hanae Zegmout, Denis Pache, Stephane Le Tual, Jean-François Roux, Jean-Louis Coutaz

Patent number: 10716294Abstract: Poultry birds in a multi-compartment cage can be removed by placing openings to each compartment on a first side of the cage, and covering each opening with a spring-loaded door wherein the spring loading is provided by an over-center spring. During transport of the birds in the cage compartment, the spring loading of each door is sufficient to prevent any bird from exiting the cage. At the delivery point, the entire cage can be tilted to the side of the openings at an angle sufficient to cause the birds to slide against and open the spring-loaded door beyond the spring's center, thereby causing the door to completely open. After the birds have slid out of the cage, the doors can be closed. Poultry birds are loaded into the cage compartments via a second door in each compartment, and each second door is disposed on a second side of the cage.Type: GrantFiled: December 12, 2018Date of Patent: July 21, 2020Inventor: Francois Roux

Patent number: 8777545Abstract: A multi-lift mast for a forklift has hydraulic circuitry that provides free lift and negative lift capabilities for the forklift. The mast comprises a stationary member, at least one extensible member slideable on the stationary member and a carriage slideable on an extensible member. The extensible mast members are raised and lowered by double acting hydraulic actuators extending between the stationary member and an extensible member. The carriage is raised and lowered by a positively connected double acting carriage hydraulic actuator extending between an extensible mast and the carriage. The circuitry employs identical pairs of counterbalance valves controlling the supply and exit of hydraulic fluid for the bore and rod ends of the actuators, set to cause the carriage to fully extend before the extensible mast members extend, providing free lift, and set to cause the extensible mast members to fully lower before the carriage lowers.Type: GrantFiled: December 26, 2009Date of Patent: July 15, 2014Assignee: Bright Coop, Inc.Inventor: Francois Roux
