  • Patent number: 11347050
    Abstract: Embodiments generally relate to systems and methods for separating an emulsion in a cavity of a device such as a liquid lens device. In one embodiment, the method comprises at least one of: applying a bias voltage to electrodes in the device, causing at least one of droplet migration, flattening of large droplets, and reduced droplet surface tension; applying an oscillating actuation voltage waveform comprising an actuation frequency to the electrodes, such that fluid pumping and turbulence is created within the device cavity; and applying an oscillating excitation voltage waveform comprising an excitation frequency to the electrodes, such that the varying electric field created by the oscillating voltage causes small droplets of the first liquid to coalesce.

  • Publication number: 20180356568
    Abstract: Embodiments generally relate to methods for preventing the formation of an emulsion in a liquid lens. In one embodiment, the method comprises fabricating a top substrate, a bottom s substrate, and a central substrate including a cavity configured to be filled by first and second liquids. The liquid lens comprising the top substrate, the bottom substrate and the central substrate is assembled, with at least one of the top substrate and the bottom substrate in the assembled liquid lens being characterized by a stabilizing feature determining that in response to an impact load on the assembled liquid lens that would cause localized pressure drops of 10 maximum magnitude X in the absence of the stabilizing feature, the maximum magnitude of localized pressure drops within the liquid lens is smaller than X.

  • Patent number: 9550521
    Abstract: A hydraulic steering arrangement (1) is provided comprising a static steering unit (2) and an adjustable pressure source (3) connected to a pressure port (4) of said steering unit (2) and having a load sensing port (21). Such a steering unit should enable a fast reaction of the steering unit.

  • Patent number: 7407374
    Abstract: The invention concerns a hydraulic machine with a toothed set comprising a toothed ring with an inner toothing, whose circumferential surface extends in parallel with its axis, and a gear wheel (3) with an outer toothing, whose circumferential surface (24) extends in parallel with its axis, at least one tooth flank having an edge as an axial end of a section, which is located between the circumferential surface and a surface directed radially inwards. It is endeavored to reduce the wear. For this purpose it is ensured that in the radial direction an edge (22, 23) ends so as to be offset inwards in relation to the circumferential surface (24).

  • Publication number: 20050180873
    Abstract: The invention concerns a hydraulic machine with a set of teeth, having a toothed ring with an inner toothing and a gear wheel with an outer toothing, the gear wheel rotating and orbiting in the toothed ring, the inner toothing and the outer toothing touching each other in contact areas, thus separating pressure chambers, and with a valve arrangement controlling a connection between a connection arrangement having a high pressure connection and a low pressure connection, and the pressure chambers. It is endeavoured to achieve a stable operation, particularly with low speeds. For this purpose, each contact area is provided with an opening, which, at the time when a pressure chamber reaches an extreme value of its volume, produces a short-circuiting with the neighbouring pressure chamber.

  • Patent number: 6739849
    Abstract: A gerotor motor has a housing located adjacent a port plate. The housing has two fluid chambers on opposite sides of a disc valve. The disc valve is in sealing surface engagement with the port plate to prevent fluid from moving between the fluid chambers. The valve assembly has forward and rearward sides and has substantially equal volumes of material removed therefrom so as to balance the port plate against any torsional forces imposed on the valve assembly which might otherwise deflect the valve assembly to interfere with its sealing relationship with the port plate.

  • Patent number: 6739848
    Abstract: A hydraulic motor of the disc valve type has a disc valve with a plurality of commutation slots that can sequentially register with ports in a port plate as the disc valve is rotated with respect to the port plate. The commutation slots have a geometrical configuration that is complimentary in shape to a portion of the geometric configuration of the ports in the port plate to reduce the resistance to fluid flow through the ports and the slots when the complimentary shapes move into or from superimposed registering positions.
