  • Patent number: 12255967
    Abstract: The present teaching relates to tracking an event at a plurality of distributed servers. In one example, an event to be tracked is determined. A user associated with the event is identified. A script is generated to be embedded in a web page. The script triggers an event message when the user performs an online behavior related to the web page in accordance with the event. The event message triggered by the script is received. A tracing flag is determined from the event message. An instruction is provided to the plurality of distributed servers for executing one or more applications based on the event and the tracing flag.

  • Patent number: 11682878
    Abstract: The present disclosure is generally directed to techniques for thermal management within optical subassembly modules that include thermally coupling heat-generating components, such as laser assemblies, to a temperature control device, such as a thermoelectric cooler, without the necessity of disposing the heat-generating components within a hermetically-sealed housing. Accordingly, this arrangement provides a thermal communication path that extends from the heat-generating components, through the temperature control device, and ultimately to a heatsink component, such as a sidewall of a transceiver housing, without the thermal communication path extending through a hermetically-sealed housing/cavity.

  • Patent number: 11320601
    Abstract: In general, the present disclosure is directed to locking arrangements for use with optical subassembly housings, such as small form-factor pluggable (SFFP) housings, that include a handle member configured to rotate about the housing to allow a user to select a target/desired orientation. Preferably, the locking arrangement couples to a pluggable housing that is configured to removably couple into a receptacle of an optical transceiver cage or other suitable enclosure. The locking arrangement further includes a handle member rotatably coupled to the pluggable housing, the handle member being configured to allow the pluggable housing to releasably lock within the receptacle. The handle member is also preferably configured to maintain a user-selected orientation such that the handle member remains at a given angle relative to the pluggable housing in the absence of a user-supplied force.

  • Publication number: 20210407080
    Abstract: Cell identification and classification is a well-known problem in the pathology domain that help identify microenvironments. In addition to the characteristic of each cell, its interactions with the neighboring regions or other cells is also important. This involves correct identification of neighboring elements and analytically representing the interactions between them. This disclosure presents a system that combines many such features, some hand engineered and some machine derived through training of Deep Learning algorithms that can be used to study the microenvironments.

  • Patent number: 9586355
    Abstract: A dynamically vulcanized alloy containing an elastomer and a thermoplastic resin is prepared by a process wherein supercritical fluid is injected into the thermoplastic elastomeric material as the material is mixed in an extruder. The material is mixed under conditions such that the thermoplastic elastomeric material is dynamically vulcanized wherein the elastomer forms a discontinuous dispersed of small particles in a continuous phase of the thermoplastic resin. The DVA material may then be directly formed into film or sheets by the use of at least one set of rolls located adjacent to the extruder outlet.

  • Patent number: 7965406
    Abstract: A circuit which uses a compressor to divide each separation image into 8-line strips, and to independently compress each strip, a single decompressor to decompress two or more color image separations, strip by strip, by interleaving them, and to apply them to two or more print heads, one for each color separation. DMA from a main memory is used to apply both separations to the decompressor, and the decompressor output is demultiplexed into two print heads, one for each separation. This is done to drive each color separation simultaneously in a single-pass color printer. Multiplexing logic controls the DMA into the decompressor and the output of the decompressor into separate buffers for each color separation. Additional logic uses the page and line sync from each print head to synchronize the accessing of the correct image raster from buffers at the output of the decompressor to the associated print head.

  • Publication number: 20110117695
    Abstract: This invention discloses a fabrication method of organic thin-film transistors (OTFTs) using the micro-contact printing. The OTFT can be of the bottom-gate or top-gate configuration. The micro-contact printing operation of this fabrication method does not require clean-room environment and high processing temperature, and does not have the problem of 2D shrinkage of the printed patterns either. Furthermore, the pre-wetting technique employed in the micro-contact printing results in improved fidelity in the pattern transfer and solves the problems of pairing and cross-talking between neighboring patterns.

  • Patent number: 7758780
    Abstract: A method of sensing melt-front position and velocity is applicable for injection-molding systems. Firstly, at least one actuation signal value of the melt-injection device of the injection-molding system is retrieved, and at least one state variable value of the injection-molding system is measured. Then, the retrieved actuation signal values and the measured state variable values are substituted into a plurality of simultaneous equations to calculate the melt-front position and velocity of the injection-molding system.
