  • Patent number: 10329639
    Abstract: A multilayer steel includes a core formed of transformation-induced plasticity (TRIP) steel. A decarburized layer is exterior to the core on at least one side thereof. The decarburized layer has reduced carbon content relative to the core. A zinc-based layer is exterior to the decarburized layer. The decarburized layer may have a composition of at least 80 percent ferrite, such that LME is reduced or mitigated. In some configurations, the decarburized layer is between 10-50 microns thick. A method of creating a coated advanced high-strength steel component is also provided. An apparatus for forming a coated advanced high-strength steel is also provided. The core of the multilayer steel may have a carbon weight-percent of less than or equal to 0.4.

  • Patent number: 10305605
    Abstract: An optical or optoelectronic receiver, an optoelectronic transceiver including the same, and a method and system for protecting a photodetector in the same are disclosed. The method of protecting a photodetector generally includes providing a control voltage to the photodetector so that a current flows through the photodetector, and determining that a transient event has occurred or a transient state exists in the receiver. During the transient event or transient state, the method maintains the control voltage at a normal operating voltage when the current through the photodetector is at or below a predetermined threshold current, and switches the control voltage to a safe mode voltage when the current through the photodetector is above the predetermined threshold current.

  • Publication number: 20190139308
    Abstract: Methods and systems are provided for performing dynamic mapping between a virtual environment and a real-world space. During dynamic mapping, a current virtual scene of the virtual environment that is within view of a user is prioritized over areas of the virtual environment that are out of view. The dynamic mapping between the virtual environment and the real-world space can be utilized to render a virtual scene for user in real-time. As a user interacts and/or moves within the virtual environment, dynamic mapping can be performed in real-time to capture any dynamic changes to the real-world space and/or the virtual environment.

  • Patent number: 10260121
    Abstract: In a method for increasing steel impact toughness, the steel composition contains from about 5 wt % to about 10 wt % manganese and has a martensite finish temperature (Mf) below room temperature. The steel composition is exposed to hot forming to form a steel part. During hot forming, the steel composition is subjected to a heat treatment temperature above its fully austenite formed temperature, is transferred to a die, and while in the die, is simultaneously formed and quenched. In one example, quenching cools the steel composition to room temperature, and the steel part is removed from the die and reheated to a baking temperature ranging from about 120° C. to about 400° C. In another example, quenching is interrupted at an interruption temperature ranging from about 120° C. to about 400° C., and the steel composition is maintained at the interruption temperature for a predetermined time and then is cooled to room temperature.

  • Publication number: 20190071747
    Abstract: A method of heat treating a steel workpiece may include two heat treatment stages. In the first stage, the steel workpiece may be heated to a first temperature greater than or equal to its A1 temperature, but less than its A3 temperature to transform the microstructure of the steel workpiece into a multiphase microstructure including grains of ferrite and grains of austenite having an average grain diameter. In the second stage, the steel workpiece may be heated to a second temperature greater than the first temperature to increase the average grain diameter of the grains of austenite. Thereafter, the steel workpiece may be cooled to ambient temperature at a rate sufficient to retain a major portion of the grains of austenite obtained during the first and second heat treatment stages. The as-heat treated steel workpiece may comprise a retained austenite phase dispersed within a ferrite matrix phase at ambient temperature.

  • Publication number: 20180333855
    Abstract: Teams of robots can be organized to collectively complete complex real-world tasks, for example collective foraging in which robots search for, pick up, and drop off targets in a collection zone. A dynamic multiple-place foraging algorithm (MPFAdynamic) is a scalable, flexible, and efficient algorithm for robot swarms to collect objects in unmapped environments. It achieves scalability through a decentralized architecture in which robots search without central control, and then return to mobile depots which provide collection and communication points. Mobile depots move closer to clusters of targets as robots discover them, which reduces robot transport time as well as collisions among robots. Flexibility is achieved by incorporating individual robot behaviors in which robots move and communicate in ways that mimic the foraging behaviors of ants.
