  • Patent number: 12313892
    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: 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: 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.

  • Publication number: 20050279220
    Abstract: The present invention provides a cup and filter combination comprising a foldable filter inside the cup. The combination further comprises a foldable retaining ring for holding the filter within the cup. The foldable retaining ring is attached to the filter along the outer edge of the filter and is attached to the inner wall of the cup to hold the filter within the cup. In a folded configuration, the retaining ring and the filter are folded inside the cup. In an open configuration, the retaining ring is pulled open from its folded configuration. In this configuration, the retaining ring has a ring shape that runs along the inner circumference of cup and the filter is opened up to receive tealeaves or coffee grounds to be brewed and filtered. The invention is not limited to brewed beverages and can also be used to filter particulate matter from a liquid.
