  • Publication number: 20220367334
    Abstract: One or more implementations of the subject technology may enable a bond-on-pad (BoP) substrate technology that can eliminate the need to utilize a solder-on-pad (SoP) process. Unlike an SoP process, a BoP Process does not require a solder bump to be formed on a bump pad to attach a joint to a bump pad. The size of an opening on a bump pad for a BoP process may be larger than that of an SoP process. A BoP process may use a solder mask having multiple thicknesses and may be thinner near the bump pads. A BoP process may use a joint having a copper pillar and a solder cap. A BoP process can be used with an underfill or a molding compound technology.

  • Publication number: 20220366896
    Abstract: The present disclosure relates to Communicational and Conversational Artificial Intelligence, Machine Perception, Perceptual-User-Interface, and a professional training method. A chatbot may comprise at least one skills module. The chatbot engages with trainee(s) on communicational training on a subject matter provided by the skills module. A trainer may create, remove, or update a skills module with interaction skills and training materials through an onboarding module. A trainee can upload recorded interactions to a skills module for evaluation or for role playing an interaction without a trainer or partner. An administrator may monitor a trainee's performance, and correlate with the organization's metrics. Based on the evaluation, the trainer or chatbot may provide the trainee with feedback and recommended improvement plans. The chatbot may be implemented in an Internet-of-Things or any device. The subject matters may extend to cover different industries/markets.

  • Publication number: 20220304409
    Abstract: Embodiments disclosed herein relate to magnetic fasteners capable of transitioning between a locked state and an unlocked state. In some embodiments, the magnetic fastener includes a first fastening portion and a second fastening portion configured to interface with one another. The first fastening portion may include a first pin with a channel configured to receive a second pin disposed on the second fastening portion. The channel may include a recess and the second pin may include a projection complementary to the recess such that the projection may be disposed within the recess when the respective central axes of the first and second fastening portions are offset. Thus, a portion of the recess may abut the projection when the respective central axes of the first and second fastening portions are offset, thus locking the first and second fastening portions relative to one another.

  • Publication number: 20200300555
    Abstract: A system and method of stabilizing operation of loop heat pipes with a controllable small inner diameter tubing bypassing LHP condenser thereby stabilizing LHP thermal operation by removing thermal-fluid oscillations. Controllability of such condenser bypass stabilizing function, can be achieved by applying a very low auxiliary power (heating or cooling) to the bypass tubing and/or to the liquid return line, without utilizing any moving parts in the LHP system. Moreover, such system with a small gas-loaded heat pipe used as a thermal strap to cool the condenser bypass housing can potentially operate in a completely autonomous manner.

  • Patent number: 10510029
    Abstract: A system tool that provides dispatchers in power grid control centers with a capability to manage changes. Included is a user interface and a plurality of scheduler engines. Each scheduler engine is configured to look ahead at different time frames to forecast system conditions and alter generation patterns within the different time frames. A comprehensive operating plan holds schedules generated by the plurality of scheduler engines. A relational database is coupled to the comprehensive operating plan. Input data is initially received from the relational database for each scheduling engine, and thereafter the relational database receives data from the scheduling engines relative to forecast system conditions.

  • Patent number: 10112316
    Abstract: A system for orienting strands (e.g., wood strands) includes multiple rotatable shafts that extend perpendicular to a travel direction of a mat of aligned strands. Each shaft can include axially spaced agitation members that extend radially away from the shaft, such as in a direction parallel to the travel direction. A vane set can be positioned vertically below the shafts. The vane set can include multiple partitions that define inter-partition spacings parallel to the travel direction. In an example, an inter-partition spacing of the vane set can be greater along a bottom portion of adjacent partitions than along a top portion of the same adjacent partitions. In an example, an upper edge thickness of a partition can be greater than a lower edge thickness of the same partition.
