  • Multicast optical switch
    Patent number: 9069139
    Abstract: A multicast optical switch uses a diffractive bulk optical element, which splits at least one input optical beam into sub-beams, which freely propagate in a medium towards an array of directors, such as MEMS switches, for directing the sub-beams to output ports. Freely propagating optical beams can cross each other without introducing mutual optical loss. The amount of crosstalk is limited by scattering in the optical medium, which can be made virtually non-existent. Therefore, the number of the crossover connections, and consequently the number of inputs and outputs of a multicast optical switch, can be increased substantially without a loss or a crosstalk penalty.

  • Cleaning appliance
    Patent number: 9066645
    Abstract: A cleaning appliance of the canister type includes separating apparatus for separating dirt from a dirt-bearing fluid flow, a floor engaging rolling assembly comprising a system for drawing the fluid flow through the separating apparatus, a chassis connected to the rolling assembly and including at least one floor engaging support member, and a duct for conveying the fluid flow to the separating apparatus. At least part of the duct is connected to the chassis for pivoting movement relative to the chassis. A biasing arrangement is provided for engaging the duct to urge the pivoting part of the duct towards a rest position relative to the chassis.

  • CURRENT COLLECTOR COMPONENT FOR A FUEL CELL
    Publication number: 20150180056
    Abstract: A current collector component (206) for a fuel cell. The current collector component (206) comprises a first electrically conductive plate (210) configured to form a wall of a fluid confinement volume of a fuel cell; and a second electrically conductive plate (212) in electrical contact with the first electrically conductive plate (210). The second electrically conductive plate (212) comprises an external electrical connection (208). The second electrically conductive plate (212) has a higher electrical conductivity than the first electrically conductive plate (210). The first electrically conductive plate (210) has a higher resistance to corrosion than the second electrically conductive plate (212).

  • Hand dryer
    Patent number: 9060657
    Abstract: A wall-mountable hand dryer arranged for drying one side of a user's hands at a time. The dryer has two nozzle sections—one for each hand—which nozzle sections are positioned towards the front of the dryer so that they are spaced away from the wall in use. The nozzle sections each extend to span the width of a user's open hand and are arranged for directing drying air down onto the front or back of said hand as it is inserted lengthwise underneath the nozzle sections from the front of the dryer. The left-hand nozzle section is banked to the right and the right-hand nozzle section is banked to the left such that the user may bank his hands accordingly in use—this makes the drying action comfortable for the user.

  • IMPROVEMENTS IN OR RELATING TO HAND DRYING
    Publication number: 20150164287
    Abstract: An arrangement incorporates a sink and a hand dryer which extends over the sink. The hand dryer is of the type which uses an air-knife mechanically to wipe the water from the user's hands. The hand dryer comprising two elongate air-knife discharge outlets—each outlet discharging a respective air-knife forwardly onto a hand of the user—the air-knife outlets being arranged side-by-side over the basin of the sink. Each air-knife outlet extends along a part of the hand dryer which is swept back at an angle such that the inboard end the air-knife outlet is in front of the outboard end of the air-knife outlet.

  • WIRELESS REMOTE CONTROL
    Publication number: 20150137958
    Abstract: A system and method a wireless remote control solution is implemented in an integrated circuit (IC) and that IC is specified to the controller manufacturer. The controller manufacturer provides an IC-compatible electromechanical interface in communication with a central processing unit (CPU) of the controller. When the manufacturer is ready to implement a wireless solution, the IC is installed into the IC-compatible electromechanical interface. Different wireless solutions and/or protocols are enabled by the manufacturer's choice of IC that is installed.
