  • Stacked semiconductor die assemblies with high efficiency thermal paths and molded underfill
    Patent number: 11239095
    Abstract: Semiconductor die assemblies having high efficiency thermal paths and molded underfill material. In one embodiment, a semiconductor die assembly comprises a first die and a plurality of second dies. The first die has a first functionality, a lateral region, and a stacking site. The second dies have a different functionality than the first die, and the second dies are in a die stack including a bottom second die mounted to the stacking site of the first die and a top second die defining a top surface of the die stack. A thermal transfer structure is attached to at least the lateral region of the first die and has a cavity in which the second dies are positioned. An underfill material is in the cavity between the second dies and the thermal transfer structure, and the underfill material covers the top surface of the die stack.

  • Composite filament 3D printing using complementary reinforcement formations
    Patent number: 11237542
    Abstract: In a method for additive manufacturing, a multi-strand core reinforced filament including a flowable matrix material and substantially continuous reinforcing strands extending in a direction parallel to a length of the filament is supplied. A first consolidated composite swath of a height less than ½ the width of the filament is deposited in a first reinforcement formation including at least one straight path and at least one curved path against a deposition surface, and a second consolidated composite swath of a height less than ½ the width of the filament is deposited in a second reinforcement formation against the first consolidated composite swath. Each deposition flows the matrix material and applies an ironing force to spread the reinforcing strands within the filament against the underlying surface and/or previously deposited swath.

  • Systems and methods for a table game using a special deck of cards and a conventional deck of cards
    Patent number: 11235227
    Abstract: Embodiments provide for card games such as blackjack that allow at least one card to be dealt from a special deck (e.g., a restricted deck) into a hand, while the remainder of the cards for that hand (and, in some embodiments, other hands involved in the game event) are dealt from a main/conventional deck. In accordance with some embodiments, the at least one card dealt from the special deck is dealt into a hand of the player while in other embodiments it is dealt into the hand of a dealer and/or an opponent player. A special deck may be a deck that includes cards configured to provide an advantage to the player (e.g., in a blackjack game, restricted deck may only include high value cards if being used for a player hand or only low value cards if being used for a dealer hand).

  • Techniques for determining geolocations
    Patent number: 11237277
    Abstract: The described geolocation techniques determine a location of an earth-based vehicle using a non-geostationary satellite. For instance, the non-geostationary satellite receives signals transmitted by the earth-based vehicle, determines the arrival times of the signals, and the position information of the satellite corresponding to the arrival times of the signals. The arrival times and position information of the satellite are sent to a signal processing unit to determine a location of the vehicle.

  • Method and apparatus for controlling cache line storage in cache memory
    Patent number: 11237972
    Abstract: A method and apparatus physically partitions clean and dirty cache lines into separate memory partitions, such as one or more banks, so that during low power operation, a cache memory controller reduces power consumption of the cache memory containing the clean only data. The cache memory controller controls a refresh operation so that a data refresh does not occur for the clean data only banks or the refresh rate is reduced for the clean data only banks. Partitions that store dirty data can also store clean data; however, other partitions are designated for storing only clean data so that the partitions can have their refresh rate reduced or refresh stopped for periods of time. When multiple DRAM dies or packages are employed, the partition can occur on a die or package level as opposed to a bank level within a die.

  • Ultrasonic lens cleaning system with foreign material detection
    Patent number: 11237387
    Abstract: Disclosed examples include lens cleaning systems, drivers and operating methods, including a transducer mechanically coupled to a lens, a driver to provide an oscillating drive signal to the transducer and a controller to control the drive signal frequency to vibrate the lens at frequencies in a range of interest. The controller determines a measured resonant frequency of the lens cleaning system in the range of interest according to a transducer feedback signal and selectively performs a lens cleaning operation if the measured resonant frequency differs from a baseline resonant frequency of the lens cleaning system for a clean lens.
