Abstract: Systems operable for monitoring a user’s operations are disclosed. The system includes a workstation and a sensor operable to obtain data from the workstation. The data is related to the user’s operation of the workstation. The system further includes a computer system in electronic communication with the sensor. The computer system is operable to receive the data from the sensor, process the data, and provide feedback to the user related to the user’s operation of the system. Methods of monitoring a user’s operation of a system are also disclosed. The method includes utilizing a sensor to obtain data and feeding the data to a computer system. The computer system processes the data and provides feedback to the user related to the user’s operation of the system.

Abstract: A computer-implemented method, system, and computer program product for predicting fatigue and injury risk for users, such as workers performing material handling operations, in real-time. Motions performed by a user, such as lifting, carrying, and manipulating objects, are captured in real-time, such as via camera-based optical devices, electromyography sensors, and inertia measurement units. Upon capturing motions performed by the user, such captured motions are utilized by a trained machine learning model to predict fatigue and injury risk to users. Such a prediction is made by the trained machine learning model by comparing the captured motions to predefined thresholds of range of motion constraints based on the biomechanical parameters of the user from a digital twin model of the user. Feedback may then be provided based on the predicted fatigue and injury risk of the user, such as in the form of video, audio, and/or haptic alerts.

Abstract: A satellite phone repeater comprises a plurality of antennas and a plurality of amplifiers coupled to the antennas. At least one of the antennas is configured to communicate with a plurality of handsets. Through the repeater, the handsets simultaneously can communicate with a satellite. The repeater may include phase shifters to ameliorate multipath interference. The repeater may also include an electronically controlled switch that couples each of two receiver/transmitters to a single antenna configured to communicate with the satellite.

Abstract: A seal puncture fitting mounted to the distal end of a spout of a liquid container including a cylindrical collar disposed about the spout in telescopic relation thereto wherein the collar is attached to the spout by a cam structure designed to allow both rotational and vertical movement of the collar in relation to the spout. A cutting blade is disposed within the collar at an upper end thereof, such that downward vertical movement of the collar causes the cutting blade to puncture a membrane seal disposed in covering, sealed relation to the spout opening. The upper portion of the collar includes a threaded outer surface for threaded engagement of a cap thereby preventing liquid from spilling between each use.
