  • Patent number: 10658346
    Abstract: A stack of strata containing LEDs is fabricated by repeatedly bonding unpatterned epitaxial structures. Because the epitaxial structures are unpatterned (e.g., not patterned into individual micro LEDs), requirements on alignment are significantly relaxed. One example is an integrated multi-color LED display panel, in which arrays of micro LEDs are integrated with corresponding driver circuitry. Multiple strata of micro LEDs are stacked on top of a base substrate that includes the driver circuitry. In this process, each stratum is fabricated as follows. An unpatterned epitaxial structure is bonded on top of the existing device. The epitaxial structure is then patterned to form micro LEDs. The stratum is filled and planarized to allow the unpatterned epitaxial structure of the next stratum to be bonded. This is repeated to build up the stack of strata.

  • Patent number: 10412806
    Abstract: Various embodiments include a multi-color micro-LED array light source that enables well-overlapped light beams of different colors. The multi-color micro-LED array light source includes a thermally conductive substrate and multiple arrays of different color micro-LEDs integrated on the thermally conductive substrate. The micro-LEDs within each array are electrically connected so that they can all be driven in unison. The multi-color array light source also includes a controller that is electrically coupled to and that drives the arrays of micro-LEDs. The controller drives the micro-LEDs in a manner that produces an output light distribution with a spatial wavelength and angular distribution that is suitable for use as a light source.

  • Publication number: 20190207868
    Abstract: A compute device can access local or remote accelerator devices for use in processing a received packet. The received packet can be processed by any combination of local accelerator devices and remote accelerator devices. In some cases, the received packet can be encapsulated in an encapsulating packet and sent to a remote accelerator device for processing. The encapsulating packet can indicate a priority level for processing the received packet and its associated processing task. The priority level can override a priority level that would otherwise be assigned to the received packet and its associated processing task. The remote accelerator device can specify a fullness of an input queue to the compute device. Other information can be conveyed by packets transmitted between and among compute devices and remote accelerator devices to assist in determining an accelerator to use or other uses.

  • Patent number: 10325893
    Abstract: Mass transfer of micro structures are effected from one substrate to another using adhesives. In the context of an integrated micro LED display, a micro LED array is fabricated on a native substrate and corresponding CMOS pixel drivers are fabricated on a separate substrate. The micro LED substrate (e.g., sapphire) and the CMOS substrate (e.g., silicon) may be incompatible. For example, they may have different thermal coefficients of expansion which make it difficult to bond the micro LEDs to the pixel driver circuitry. The micro LED array is transferred to an intermediate substrate (e.g., silicon) by use of an adhesive. This intermediate substrate may be used in a process of bonding the micro LED array to the array of pixel drivers. The intermediate substrate is separated from the micro LED array by releasing the adhesive.

  • Patent number: 10304375
    Abstract: A display panel with integrated micro-reflectors. The display panel also includes an array of pixel light sources (e.g., micro-LEDs) electrically coupled to corresponding pixel driver circuits (e.g., FETs). The micro-LEDs produce light and the micro-reflectors reduce the divergence of the light produced by the micro-LEDs. Different designs are possible. The micro-reflectors can have different shapes, include the shape of their sidewalls and the shape of their plan cross-section. The array schemes can also vary, including the number of LEDs per micro-reflector. Different fabrication approaches are also possible. In one approach, a support structure is integrated between micro-LEDs. The sides of the support structure are reflective and serve as the reflective sidewalls of the micro-reflector. Alternately, the LED mesa itself can serve as the support structure.

  • Patent number: 10069381
    Abstract: An electric motor includes a stator and a rotor. The stator includes a motor housing with an open end and an end cover mounted to the open end. The rotor includes a rotor shaft that extends through the end cover. The end cover includes a bearing that supports the rotor shaft. The rotor shaft and motor housing are made of an electrically conductive material and are electrically connected with each other. The motor housing, end cover, bearing and rotor shaft cooperatively form an electromagnetic shield suppressing electromagnetic interference generated by the motor. Optionally, the rotor shaft drives a coaxial worm shaft of a gearbox by an insulating member, which further suppresses electromagnetic interference.

  • Patent number: 10033650
    Abstract: Systems and techniques for processing and/or forwarding packets are described. An ingress switch can use a QoS mapping mechanism to map a first set of Quality of Service (QoS) bits in a packet received from a customer to a second set of QoS bits for use in a Transparent Interconnection of Lots of Links (TRILL) packet which encapsulates the packet. The first set of QoS bits can be different from the second set of QoS bits. The TRILL packet can be processed and/or forwarded in the network based on the second set of QoS bits. At the egress switch, the TRILL packet can be decapsulated and the original packet with the original QoS bits (or QoS bits that are different from the original QoS bits) can be forwarded to the customer's network. In this manner, some embodiments of the present invention can preserve the QoS bits across a TRILL network.
