  • Publication number: 20250128708
    Abstract: Systems and methods for controlling the speed of a vehicle traveling over a terrain. The methods comprise: predicting, by a mobile device (MD), a queue length defined by the number of vehicles in a queue at a downstream intersection based on a traffic volume and vehicle speeds that were detected during a past period of time by a detector located at or near an upstream intersection; sensing, by MD's sensor(s), the vehicle's velocity and location; computing a distance to a downstream intersection from the vehicle's location; generating a desired speed for the vehicle based on the traffic volume and vehicle speeds, signal phase and timing data for at least the next two cycles, the predicted queue length at the downstream intersection, the vehicle's velocity and location, the distance to the downstream intersection, and a current time; and using the desired speed to facilitate control of the speed of the vehicle.

  • Publication number: 20250095672
    Abstract: The present embodiments relate to a write head design with a patterned hot seed (HS). Particularly, the HS can be patterned as part of a multi-step patterning process that can partially or completely remove portions of the HS at multiple sides to form various designs. For example, the HS can have a two-step cliff design, etching multiple steps around an un-patterned center portion, and a flared angle. The designs of the patterned HS can improve write head performance.

  • Patent number: 12168768
    Abstract: The present invention is directed to a yeast strain, or strains, secreting a full suite, or any subset of that full suite, of enzymes to hydrolyze corn starch, corn fiber, lignocellulose, (including enzymes that hydrolyze linkages in cellulose, hemicellulose, and between lignin and carbohydrates) and to utilize pentose sugars (xylose and arabinose). The invention is also directed to the set of proteins that are well expressed in yeast for each category of enzymatic activity. The resulting strain, or strains can be used to hydrolyze starch and cellulose simultaneously. The resulting strain, or strains can be also metabolically engineered to produce less glycerol and uptake acetate. The resulting strain, or strains can also be used to produce ethanol from granular starch without liquefaction.
