Abstract: In an online conference session involving a presenter at an endpoint device and a plurality of attendees at respective endpoint devices, screenshots of content displayed at the endpoint device of the presenter and content displayed at the endpoint devices of each of the attendees are captured on a periodic basis. First data is stored that represents screenshots of content displayed at the endpoint device of the presenter and of content displayed at the endpoint devices of each of the attendees for each screenshot capture instance. Second data is stored that represents captured screenshots at each of a plurality of screenshot capture instances at the endpoint device for each attendee during the conference session. An attention metric is generated for one or more attendees based on the first data and second data.

Abstract: The invention discloses a method for precisely estimating the remaining capacity of a rechargeable battery in a practical system. To evaluate the remaining capacity of a battery through a calibrated current which is calculated from a predictable capacity close to the end of discharge or to the end of full charge, so that the remaining capacity of battery will approach end points smoothly. A system can thus detect battery status and take necessary actions safely. Battery aging problem is considered while calculating the remaining capacity and the full charge capacity (FCC) of battery is also updated according to the total cumulated charges during a charge or discharge stage.

Abstract: The invention discloses a method for precisely estimating the remaining capacity of a rechargeable battery in a practical system. To evaluate the remaining capacity of a battery through a calibrated current which is calculated from a predictable capacity close to the end of discharge or to the end of fill charge, so that the remaining capacity of battery will approach end points smoothly. A system can thus detect battery status and take necessary actions safely. Battery aging problem is considered while calculating the remaining capacity and the full charge capacity (FCC) of battery is also updated according to the total cumulated charges during a charge or discharge stage.

Abstract: A shape cutting apparatus is provided having a lower mold body that can cut characteristic openings within the outer shape of sticker whose outer contour is cut by an upper mold body. When the outer shape of the sticker is cut, the inner characteristic openings are also cut at the same time. A protrude-out device that pushes out the finished sticker has a contour that is the same as the finished sticker.

Abstract: An apparatus for forming a selectively-shaped paper cut-out comprises a cutting table assembly which has a plurality of cutting means disposed therein, In one embodiment, the cutting table assembly is rotatably mounted to a base member within a U-shaped support bracket extending therefrom. In another embodiment, the cutting table assembly is not mounted on a base member; rather, it has the necessary actuating means in place to independently actuate each of the plurality of cutting means provided therein. To use the apparatus, a user simply turns the cutting table assembly to choose the desired shape, inserts a sheet of paper into the assembly, and punches out the desired shape.

Abstract: A contact lens cleaning apparatus having a clockwork controlled by a rotary knob to turn a ratchet wheel against a pawl, causing the lens cage to oscillate in the cleaning solution in the container, wherein the lens cage consists of two symmetrical semispherical gratings hinged together and retained in the closed position by a fastener for carrying the left eye contact lens and the right eye contact lens respectively.
