US11023596B2	Non-rasterized image streaming system that uses ray tracing samples Secure rendering system that creates ray tracing samples with obfuscated positions, so that images can only be viewed by an authorized consumer able to recover the sample positions. Obfuscation of ray directions is integrated into the rendering process, for example by incorporating encryption into a lens shader. The rendering system never stores or transmits an image without obfuscating positions, so even the rendering system cannot see the image it is rendering. Embodiments may use public key cryptography, so that encryption of sample positions is done with a public key, and only the owner of the secret private key can view the rendered image. Since keys are asymmetric, the rendering system cannot decrypt the obfuscated samples. Piracy of rendered images is therefore mitigated. Some compositing operations may be performed on the secure rendering output prior to decrypting sample positions; for example, colors may be modified globally or for selected objects.

US11022412B2	Morris 80 plastic apollo bolt When combined with a metal point, this ten inch plastic pistol crossbow bolt is designed to extend past the barrel of a pistol crossbow so it can be used for small game hunting, pistol crossbow fishing, recreational shooting and competition shooting. The major fault of the standard bolt commonly used with a pistol crossbow is, they are less than seven inches in length and do not extend past the end of a pistol crossbow barrel. Therefore, their use is limited to target points and recreational shooting only. Other faults of the standard short bolts are their high travel speed. They are very difficult to be viewed in flight, causing most bolts to be lost after one use. Also, because of their irretrievability from any commonly used target, they cannot be found and scored in any type of shooting competition. This ten inch bolt is a solid one piece unit made of a strong but, light weight plastic compound. It has a NOCK to securely hold the bow string in place. Standard pistol crossbow bolts do not have a nock. It has two ROUNDED WINGS and a stabilizing TAIL which creates an accurate and stable bolt flight. No other pistol crossbow bolt has rounded wings and a tail. These features allow this bolt to be easily viewed in flight. The shaft has a THREADED TIP to accept almost any type metal point. The major advantage of this new bolt over other patented bolts of this size is the rounded wings. The rounded wings gives this bolt added body weight. This added body weight requires additional point weight to balance with that heavier body weight. This heavier bolt body gives this bolt the added weight needed for knock-down power in small game hunting and, the necessary added weight for better water penetration when used for pistol crossbow fishing.
