CPC Class H04N

Provided are embodiments for method performing elevator condition-based maintenance using an in-car camera. The method includes monitoring one or more conditions of an elevator system, and analyzing image data obtained from monitoring one or more conditions of the elevator system. The method also includes validating the one or more conditions of the elevator system, and executing an action based on the validation of the one or more conditions. Also provided are embodiments for a system for implementing the method described herein.

This display system is provided with: an image acquisition unit for acquiring a captured image obtained by capturing an image around a work vehicle; a detection unit for detecting an obstacle around the work vehicle; and a display control unit which, on the basis of the result of detection of the obstacle, generates a signal for displaying a marker image in a position corresponding to the obstacle, and a signal for causing the form of the marker image to change over time.

Systems, devices, and methods for drain cleaning using high voltage, high frequency AC electrical power supplied through a video push-cable are disclosed. In one embodiment, a drain cleaning system may include a cable for carrying electrical control and/or data signals as well as alternating current (AC) power at a high voltage and high frequency relative to AC mains frequencies.

A method of encoding video including: writing a plurality of predetermined buffer descriptions into a sequence parameter set of a coded video bitstream; writing a plurality of updating parameters into a slice header of the coded video bitstream for selecting and modifying one buffer description out of the plurality of buffer descriptions; and encoding a slice into the coded video bitstream using the slice header and the modified buffer description.

Camera heads and associated systems, methods, and devices for inspecting and/or mapping pipes or cavities are disclosed. A camera head may be coupled to a push-cable and may include one or more image sensors to capture images and/or videos from interior of the pipe or cavity. One or more multi-axis sensors may be disposed in the camera head to sense data corresponding to movement of the camera head within the pipe or cavity. The images and/or videos captured by the image sensors may be used in conjunction with the data sensed by the multi-axis sensors to generate information pertaining to the pipe or cavity may be generated.
