  • Patent number: 11838575
    Abstract: A media stream receiver is provided for scalable physical layer flow of packetized media streams. The media stream receiver replicates the processing block in time, rather than in hardware, through the use of a single shared memory and pointer alignment calculations, which combines multiple buffering stages as the single, shared memory buffer to offer redundancy and alignment, while acting as a receiver buffer to account for packet delay variations. By doing so the media stream receiver can perform a vertical interval switch between received media streams.

  • Publication number: 20230032318
    Abstract: A system and method is provided for performing lossless switching in a redundant multicast network. An exemplary method includes receiving a primary media stream and a redundant media stream over different forwarding network paths by network ports of a receiver communicatively coupled to an A/V device. Furthermore, the receiver outputs media data of the media streams to the A/V device to be presented thereon. In response to a control signal to switch the receiver to a new primary media stream, the method disconnected either the primary ort the redundant media streams from the respective network port of the receiver receiving that stream. Furthermore, the method includes controlling the disconnected network port to receive the new primary media stream and then outputting media data of the new primary media stream to the A/V device to be presented thereon.

  • Patent number: 8975193
    Abstract: A microfabricated device is fabricated by depositing a first metal layer on a substrate to provide a first electrode of an electrostatic actuator, depositing a first structural polymer layer over the first metal layer, depositing a second metal layer over said first structural polymer layer to form a second electrode of the electrostatic actuator, depositing an insulating layer over said first structural polymer layer, planarizing the insulating layer, etching the first structural polymer layer through the insulating layer and the second metal layer to undercut the second metal layer, providing additional pre-formed structural polymer layers, at least one of which has been previously patterned, and finally bonding the additional structural layers in the form of a stack over the planarized second insulating layer to one or more microfluidic channels. The technique can also be used to make cross over channels in devices without electrostatic actuators, in which case the metal layers can be omitted.

  • Publication number: 20130032235
    Abstract: An integrated microfluidic check valve has a first chamber having inlet and outlet ports and divided by a barrier the said inlet and outlet ports into first and second subchambers. A membrane forms a wall of the first chamber and co-operates with the barrier to selectively permit and prevent fluid flow between the inlet and outlet ports. A second chamber adjoining the first chamber and has a wall formed by the membrane. A microfluidic channel establishes fluid communication between the second chamber and the first subchamber. The membrane deflects to permit fluid flow around the barrier when the pressure in the first subchamber is lower than the pressure in the second subchamber. Two such valves can be combined into a peristaltic pump.

  • Patent number: 7927904
    Abstract: A MEMS device is manufactured by first forming a self-aligned monolayer (SAM) on a carrier wafer. Next, a first polymer layer is formed on the self-aligned monolayer. The first polymer layer is patterned form a microchannel cover, which is then bonded to a patterned second polymer layer on a device wafer to form microchannels. The carrier wafer is then released from the first polymer layer.
