Abstract: A system and method for measuring the time of a moving object during at least one training exercise is disclosed. The system includes a mobile device having a camera and a time measurement computer program. After placing the mobile device in a fixed stationary viewing angle position, the camera is arranged to capture digital images and to enter an image calibration mode, an algorithm calibration mode, and a detection mode before executing a time measuring command on the computer program. The system and method utilize histogram calculation for the digital images to trigger the time measuring command and read object movement detection when threshold values are detected.

Abstract: The preparation of a pepsin extract from the stomach of pigs, sheep or cattle, which is suitable for the bating of hides, is presented. The process involves macerating the stomach mucous, sedimenting the material, reserving the middle layer for pharmaceutical preparation, combining the other two layers, drying them and adding salt for preservation. The resulting pepsin containing material is particularly suitable for acid enzymic bating of chrome tan hides after the pickle process with the main purpose of obtaining a higher surface yield and a softer leather.
