  • Publication number: 20240120682
    Abstract: An apparatus includes a first element and a second element configured to be repeatedly mechanically coupled to and decoupled from one another, a first seal between the first element and the second element, and a second seal between the first element and the second element. The first seal is configured to inhibit moisture ingress from an environment surrounding the first and second elements to a first region enclosed at least partially by the first seal and the second seal is configured to inhibit moisture ingress from the first region to a second region enclosed at least partially by the second seal. One of the first and second seals includes two first surfaces of the first and second elements in contact with one another, and another one of the first and second seals includes a second surface and a resiliently bendable protrusion of the first and second elements in contact with one another.

  • Patent number: 11488315
    Abstract: A visual and geolocation analytic system is provided, including: an analytic device and a number of image capturing devices connected to said analytic device. The image capturing devices capture images of an object at a time interval and send said captured images to said analytic device; said analytic device comprises a deep learning model for analyzing said captured images, allowing said object to be identified and tagged, and allowing a path of movement of said object across time to be tracked. The present invention tracks the position of an object within an area continuously across time, and transform the object in captured images into structured data set for analysis.

  • Publication number: 20220149230
    Abstract: A super luminescent light emitting diode includes an active waveguide that is grown using selective area epitaxy, a resistance array, and a contact pad. The active waveguide has a varying bandgap due to a width of the mask that is used for growing the active waveguide. The active waveguide is injected with varying current at each longitudinal section of the active waveguide due to varying resistance associated with the resistance array at each longitudinal section. The varying current is injected by the contact pad. The contact pad is a single continuous electrode. The varying bandgap and varying current at each longitudinal section of the active waveguide enable emission of optical light by each section of the active waveguide such that a combination of all the emitted light leads to emission of a super-broadband continuous spectrum and tailorable spectrum profile of the optical light.

  • Publication number: 20220019021
    Abstract: A photonic integrated circuit (PIC) includes various mode field adapters (MFAs), a waveguide, and various contact pads. All the MFAs are on a same facet of the PIC. One MFA of the PIC outputs a first optical signal that is an amplified version of a second optical signal. The waveguide is divided into two waveguide arms and a bend portion to join the two waveguide arms. The waveguide extends between the MFAs such that the second optical signal propagates through the waveguide. Further, each waveguide arm is formed between the contact pads. The second optical signal propagating through the waveguide is amplified based on a current that is injected in the PIC by way of the contact pads.

  • Patent number: 8848716
    Abstract: In one embodiment, line cards of packet switching or other network devices are configured for terminating pseudowires. Typically, this includes multiple line cards being configured for terminating a same pseudowire, which allows the corresponding pseudowire traffic to be received by any one of these multiple line cards. Each of these pseudowire-terminating line cards is typically configured to apply one or more features to a pseudowire packet. Examples of these features include, but are not limited to: Access Control List, Quality of Service, Netflow, and Lawful Intercept. For a received packet to be sent out one of these pseudowires, a two-stage lookup operation can be used to first identify the pseudowire over which to forward the packet; and a second lookup operation based on the pseudowire to identify forwarding information corresponding to a path through a network over which a corresponding pseudowire is configured.
