20120130449 | COCHLEAR IMPLANT APPARATUS AND METHODS - The invention relates to cochlear implants and to improved methods of operating such implants. We describe cochlear implant apparatus comprising an audio signal processing unit with a wired or wireless coupling to an implantable cochlear stimulation device, wherein said audio signal processing unit has an audio input to receive an audio signal representing a sound, wherein said implantable cochlear stimulation device includes an electrical pulse generator coupled to an electrode array for intracochlear stimulation, wherein the apparatus is configured to apply stimulation to said electrode array to represent said sound, wherein said stimulation comprises application of an electrical pulse across two intracochlear electrodes of said electrode array, and wherein said electrical pulse has a pulse waveshape which is asymmetric under an operation comprising inverting the waveshape about a zero level and then time reversing the waveshape. | 05-24-2012 |

20160123761 | LINEAR ROUTE PROGRESS INTERFACE - One or more techniques and/or systems are provided for providing linear route progress. For example, a linear route progress interface, comprising a linear route representation of a route from a starting location to a destination location, may be displayed. The linear route representation may linearly represent a progress of the user along the route (e.g., as opposed to directions on a map that may otherwise visually overwhelm a user merely interested in traffic flow and/or incident information that may affect an arrival time of the user). The linear route progress interface may be populated with traffic flow indicators (e.g., traffic flow speed) and/or incident indictors (e.g., indicating accidents, construction, etc.). A user indicator, corresponding to a current position of the user, may be populated within the linear route progress interface. The user indicator and/or the linear route representation may be modified to illustrate user progress along the route. | 05-05-2016 |

20090050046 | Davit Assembly and a Method for Moving a Boat - An onboard davit assembly for launching a boat from a ship is disclosed. In at least one embodiment, the assembly includes two spaced apart davits, each davit including a substantially horizontal boom, a hoist cable extending downwards from a suspension frame on the boom and including at least one fixation device at its lower end to which the boat can be attached. In at least one embodiment, the assembly is arranged such that the booms are movable between an inward position wherein the suspension frames extend inboard and an outward position wherein the suspension frames extend outboard, wherein the booms extend from an onboard vertical pivot axis and can rotate in a horizontal plane around the pivot axis, and wherein the suspension frames are movable along the booms such that a distance between the suspension frames remains constant during rotation of the booms between the two positions when the boat is moved from a parking position to a launching position. | 02-26-2009 |

20090139141 | Automatic door opener - An automatic door opener is attachable to at least one manual door and an automatic door. The automatic door has a closed position and an open position. The automatic door opener includes an opening actuator, a pressure reservoir and a door activator. The opening actuator is operably connected to the automatic door. The pressure reservoir system is operably connected to the opening actuator, operably connected to the manual door, and operably connected to the automatic door. Movement of the manual door adds pressure to the pressure storage reservoir system. The door activator has an at rest position and an open position whereby pressure from the pressure reservoir system is released to the opening actuator moving the automatic door from a closed position to an open position responsive to movement of the door activator form the at rest position to the open position. | 06-04-2009 |
