Abstract: Techniques and apparatuses enabling high accuracy video object detection using reduced system resource requirements (e.g., reduced computational load, shallower neural network designs, etc.) are described. For example, a search domain of an object detection scheme (e.g., a target object class, a target object size, a target object rotation angle, etc.) may be separated into subdomains (e.g., such as subdomains of object classes, subdomains of object sizes, subdomains object rotation angles, etc.). Specialized, subdomain-level object detection/segmentation tasks may then be separated across sequential video frames. As such, different subdomain-level processing techniques (e.g., via specialized neural networks) may be implemented across different frames of a video sequence. Moreover, redundancy information of consecutive video frames may be leveraged, such that specialized object detection tasks combined with visual object tracking across consecutive frames may enable more efficient (e.g.

Abstract: An apparatus, for example, the imager of a printer is disclosed. The apparatus comprises an elongate member including an optical element. At least one bearing supports the member to allow rotation about a lengthwise axis of the member. An actuator comprises a plurality of load sharing motors to apply torque to the member at a plurality of locations, the locations being spaced apart along the length of the member.

Abstract: An engine system with advance detection of detonation and/or pre ignition, the system comprising an engine, operative for propulsion of a vehicle by generating rotational motion, whose rotational velocity over time is monitored; and a detonation and/or pre ignition detector operative to provide an alert for impending detonation and/or pre ignition of the engine, if the rotational velocity fluctuates over time to an extent which is predetermined to be unsafe.

Abstract: An attachment for a towelette container provides a path through which the towelettes pass as they are removed from the container and a heater warms the towelettes as they are in and move through the path. The attachment is detachably secured to the container so that it can be used on new containers as the original containers become depleted of their contents. The heater can be an incandescent bulb and the outer wall of the attachment can be at least partially light-transmissive, so that the attachment can also function as a lamp or night light.
