Abstract: A sensorless temperature sensing and control system and method uses electrical voltage and current feedback signals to monitor and control the temperature of heating elements used in a heat sealing process wherein sensors are not physically connected to a heat seal bar during the heat sealing process. After calibration of a heat seal bar using a sensor, voltage and current feedback signals are processed by a programmable logic controller (PLC) to calculate the real-time electrical resistance of each heating element. Data and electrical resistance is used to calculate real-time temperature of the heat seal bar during heating.

Abstract: The present teaching relates to ranking search content. In one example, a plurality of documents is received to be ranked with respect to a query. Features are extracted from the query and the plurality of documents. The plurality of documents is ranked based on a ranking model and the extracted features. The ranking model is derived to remove one or more documents from the plurality of documents that are less relevant to the query and order remaining documents based on their relevance to the query. The ordered remaining documents are provided as a search result with respect to the query.

Abstract: A preFEC BER of a selected optical link is determined. A FEC Detected Degrade (FDD) threshold, FEC Excessive Degrade (FED) threshold, and FEC limit threshold are obtained for the selected optical link. The FDD threshold is less than the FED threshold and the FED threshold is less than the FEC limit. Based on the FDD threshold, FED threshold, the FEC limit, and a determination that a postFEC BER==0, it is determined whether a link down condition of the selected optical link can be asserted or de-asserted.

Abstract: Aspects of the present disclosure are directed to a holographic calling system providing holographic calling between an artificial reality device and a mobile device having both front and back facing cameras. The user of the mobile device can position it so one of the cameras is pointed toward their face and another camera captures the user's hand not holing the mobile device. The holographic calling system can automatically determine the position of the mobile device in relation to the user's face and hand. Once the mobile device is positioned within an appropriate capture zone, the captured images of the user's face are used to create a first representation of the sending user's face, the captured images of the user's hand are used to create a second representation of the sending user's hand. Each representation is provided as output from a receiving artificial reality device, positioned relative to each other.
