  • Patent number: 12634412
    Abstract: A computer-implemented method of operating a video conference endpoint. The video conference endpoint includes a video camera which captures images showing a field of view. The method comprises: receiving data defining of a spatial boundary within the field of view, the spatial boundary being at least in part defined by a distance from the video camera; capturing an image of the field of view; identifying one or more persons within the field of view of the video camera; estimating a position of the or each person within the field of view of the video camera; and generating one or more video signals, which include one or more cropped regions corresponding to one or more persons determined to be within the spatial boundary, for transmission to a receiver.

  • Patent number: 9005042
    Abstract: A combined CV joint boot and inner seal includes a boot portion having a first end and a second end and having a shaft sealing portion at the first end for sealing with a first shaft of the CV joint. A front can sealing portion is positioned at the second end of the boot portion. An inner seal portion extends generally inwardly towards the CV joint longitudinal axis to block lubricant from migrating into the interior of the boot portion.

  • Patent number: 8287393
    Abstract: An inner seal is provided for protecting a CV joint boot for a CV joint. The CV joint includes a bearing, a back sealing means and a front can. The bearing operatively connects a first shaft and a second shaft. The bearing has an inner race and an outer race and has a front and a back. The first shaft is connected to the inner race. The second shaft is connected to the outer race. The front can is connected to the outer race. The back sealing means seals against leakage of lubricant from the back of the bearing. The inner seal comprises an inner seal body having a front can sealing portion for sealing with the front can to inhibit the migration of lubricant from the bearing therebetween. The inner seal body has a shaft sealing portion for sealing with the first shaft to inhibit the migration of lubricant from the bearing therebetween. The inner seal body has a shield portion that extends between the front can sealing portion and the shaft sealing.
