Publication number: 20250343947Abstract: At least one embodiment is directed towards a computer-implemented method for generating compressed video content. The computer-implemented method includes the steps of receiving a plurality of triplanes associated with video content; extracting channel range values from each triplane included in the plurality of triplanes; normalizing the plurality of triplanes based on the channel range values to generate a plurality of normalized triplanes; storing the channel range values with the plurality of normalized triplanes; generating a plurality of tiled triplanes based on the plurality of normalized triplanes; compressing the plurality of tiled triplanes to generate compressed video content; and transmitting the compressed video content to an endpoint device. Another embodiment is directed towards a computer-method for rendering video content. Yet another embodiment is directed towards a computer-implemented method for training generative artificial intelligence (AI) models.Type: ApplicationFiled: April 30, 2025Publication date: November 6, 2025Inventors: Michael STENGEL, Amrita MAZUMDAR, Koki NAGANO, Matthew CHAN, Shalini DE MELLO, Alex EVANS, David LUEBKE

Publication number: 20250232267Abstract: An embodiment includes a method of automated environment management using an analog environment device. The method involves generating a virtual device that represents the analog environment device by mapping a template to a digital form configured to receive manual input related to the device's attributes. Data received from the digital form is interpreted as coming from the virtual device and is normalized into a common format for system management. Based on the normalized data, the system determines if a defined condition exists in the environment related to the analog device or the environment itself. If such a condition is detected, the system triggers an automated action to address it.Type: ApplicationFiled: January 14, 2025Publication date: July 17, 2025Applicant: Ivanti, Inc.Inventors: Alex Evans, David Brugneaux

Patent number: 9365228Abstract: In one embodiment, a coast control system, or dead-man brake inhibitor, is associated with a tiller arm that is used for steering a vehicle. A spring acts upon the tiller arm when an operator releases a control handle attached to the tiller arm to move the tiller arm to a braking position which causes an electronically or mechanically actuated brake to be applied. Before releasing the control handle, the operator may actuate the coast control system to inhibit movement of the tiller arm towards the braking position when the control handle is released. The operator may vertically reposition the tiller arm while the coast control system remains actuated by overcoming the inhibiting force applied by the coast control system when the tiller arm is moved toward the braking position and by overcoming the spring acting on the tiller arm when the tiller arm is moved away from the braking position.Type: GrantFiled: April 4, 2014Date of Patent: June 14, 2016Assignee: Hyster - Yale Group, Inc.Inventors: Robert Clay Dunigan, Jeff Monico, Alex Evans, Allen Brock, Lisa French
