Abstract: An early alert system and a method for livestock disease detection are disclosed. An activity measurement zone (AMZ) is defined near an incentive device (e.g. a livestock feeder) with an RFID tag reader and a uniquely-designed feedlot fence crossbar-embedded RFID antenna, which amplifies multiple signal wavelengths in a single dipole antenna. The early alert system is configured to detect and count an animal's access into the AMZ with an RFID tag attached to the animal. If the animals' activity relative to the AMZ drops to an alarmingly low level (e.g. dropping below an alert trigger point) over time, then a user of the early alert system is informed of a potential health problem of the animal and may also be encouraged to inspect the animal in person for further determination of its current health and potential medical issues.

Abstract: Embodiments of the present disclosure relate to continuous and/or binocular time warping methods to account for head movement of the user without having to re-render a displayed image. Continuous time warping allows for transformation of an image from a first perspective to a second perspective of the viewer without having to re-render the image from the second perspective. Binocular time warp refers to the late-frame time warp used in connection with a display device including a left display unit for the left eye and a right display unit for the right eye where the late-frame time warp is performed separately for the left display unit and the right display unit. Warped images are sent to the left and the right display units where photons are generated and emitted toward respective eyes of the viewer, thereby displaying an image on the left and the right display units at the same time.

Abstract: A movement notification is received from a display. The movement notification corresponds to a movement. A set of movement frames that reflect the movement is rendered by a graphical processing unit. The set of movement frames is transmitted to the display. A notification that the movement has ceased is received from the display. A stop command is transmitted to the display. The stop command instructs the display to not display the first subset of frames in the set of movement frames. The first subset of frames reflects the end of the movement.

Abstract: A method for generating an augmented reality image from first and second images, wherein at least a portion of at least one of the first and the second image is captured from a real scene, identifies a confidence region in which a confident determination as to which of the first and second image to render in that region of the augmented reality image can be made, and identifies an uncertainty region in which it is uncertain as to which of the first and second image to render in that region of the augmented reality image. At least one blending factor value in the uncertainty region is determined based upon a similarity between a first colour value in the uncertainty region and a second colour value in the confidence region, and an augmented reality image is generated by combining, in the uncertainty region, the first and second images using the at least one blending factor value.
