  • Patent number: 12623522
    Abstract: A panel top assembly adapted for a vehicle including a pivotal portion that is rotatable between a closed position and open sunroof position, the pivotal portion is coupled to guide assemblies to selectively slide rearward to another top open position. There is provided a removable hard rear window, a rear hard drip rail; and a pair of removable hard rear side window assemblies on the side of the vehicle that wrap around to the back of the vehicle creating clear rear hard corners and that are also in sealing engagement to the rear window. The rear hard drip rail and pivotal portion selectively drop down at an angle into the rear cargo area of the vehicle when a fully open top experience is desired.

  • Patent number: 12609990
    Abstract: Systems and methods for secure portals between virtual worlds are provided. In some embodiments, the systems and methods include deploying a secure portal between two virtual worlds. This is performed by rendering a top cell for a first virtual world. Rendering includes a transparent region overlapping a portal. Then an intermediate cell is layered underneath the top cell. This intermediate cell comprises the portal. A message is received from the top cell. The message includes a minimum rendering size, shape and at least one transform. This message is transferred to a bottom cell for a second virtual world, where it is rendered (in part) responsive to the message. The top cell, the intermediate cell and the bottom cell are then layered to generate a scene. In some embodiments, the rendered portion of the bottom cell comports to the minimum rendering size, and the intermediate cell is transparent. In some cases, the cells are either iFrames, or separate applications.

  • Patent number: 12592597
    Abstract: A radial flux electric motor includes a stator having a radially inner stator surface and stator windings arranged thereon. The motor also includes a rotor mounted inside the stator and configured to rotate relative thereto about an axis. The rotor has a rotor core constructed from a ferromagnetic material having relatively high magnetic permeability and defined by a rotor outer surface establishing an airgap between the rotor and the stator. The rotor also has a plurality of magnetic poles set in the rotor core and configured to generate magnetic flux. The rotor additionally has inserts constructed from a material having relatively low magnetic permeability in at least one geometric direction. Each insert is mechanically fixed to the rotor core to thereby control magnetic flux distribution and minimize flux leakage inside the rotor.

The motor also includes a rotor mounted inside the stator and configured to rotate relative thereto about an axis. The rotor has a rotor core defined by a rotor outer surface and includes magnetic poles configured to generate magnetic flux and defining flux leakage zones. The motor additionally includes a selective permeability sleeve arranged circumferentially on the rotor and fixed to the rotor outer surface, thereby establishing an airgap between the sleeve and the stator. The sleeve provides reinforcement to the rotor core and to the magnetic poles and includes regions of relatively high and relatively low magnetic permeability alternating around the rotor outer surface. The regions of relatively low magnetic permeability are arranged radially outward and across from the flux leakage zones to control magnetic flux distribution in the motor.

  • Patent number: 12413326
    Abstract: Systems and methods for a shared virtual environment are provided. The systems and methods include a unique architecture where domains known as “islands” are replicated across various local machines. These islands include objects that publish events. These events include messages that are provided from the island's controller, to a reflector for the addition of a timestamp. The timestamp ensures computational synchronization between all mirrored islands. The timestamped messages are provided from the reflector back to the controllers of the various islands. The controllers incorporate these messages into the existing message queue based upon the message timing. The local machines then execute the messages in time order, until the external message indicates. These timestamp “heartbeats” thus dictate the execution activity across all islands and ensure synchronization of all islands.

  • Patent number: 12311755
    Abstract: A vehicle transaxle comprising a plurality of mounting flanges fixedly mountable to an axle tube of the vehicle absent any additional structure for mounting the transaxle to the vehicle. The axle tube houses a wheel axle to which the transaxle is operably couplable. The transaxle additionally comprises a transaxle mounting collar that is fixedly mounted to or integrally formed with a housing of the transaxle. The mounting collar is structured and operable to have a prime mover of the vehicle mounted thereto and to support the weight/mass of the prime mover such that the prime mover is mountable to the vehicle via only the mounting collar absent any additional structure for mounting the prime mover to the vehicle such that the prime mover can be cantilevered from (e.g., suspended from) the transaxle, e.g., the prime mover is ‘free floating’.

  • Patent number: 12145066
    Abstract: Systems and methods for a unitary physics engine and image smoothing is provided. In this method, a game and a plug-in physics engine are initialized on multiple gaming systems. Time advancement messages are received by a controller within the physics engine from a reflector, causing the physics engine to compute events in a queue up to the time of the timing message, according to the same set of physics rules. This causes a deterministic computation of all object positions within the game that is identical across all gaming systems. In between the deterministic calculations, the local gaming system may compute speculative object positions, based upon the last deterministic position and the accelerations, velocities and object attributes at that moment. These speculative calculations may be performed at least as often as the frame rate of the display (typically 30, 60 or 120 frames per second).
