    Abstract: A safety system for a power miter saw comprises a support member, at least one multidirectional manipulator including a workpiece holder member moveably mounted to the support member for securing a workpiece in place, and a control box. The workpiece holder member includes a presence indicator operatively connected to the control box and configured to detect the physical presence of a saw operator's hand on the at least one multidirectional manipulator when the saw operator's hand engages the presence indicator. The control box is operatively connectable to a trigger switch of the power miter saw so that an electric motor of the power miter saw is activated only when both the presence indicator of the safety system and the trigger switch of the power miter saw are engaged by both hands of an operator of the power miter saw.

    Abstract: An entry system includes a plurality of first user devices, such as key fobs, ID cards and the like. A plurality of second user devices are maintained by users, and may include mobile phones, smart watches and tablets. A main entry system controls a barrier to allow entry to approved individuals. An authorization system is configured to validate the first and second user devices, and to send an electronic questionnaire to the second user device. The user must complete the questionnaire and transmit it to the main entry system. The second user device, the main entry system, and the authorization system communicate with each other over a computer network. If the user successfully completes the questionnaire and the user's identity is authenticated, the main entry system allows the barrier to be opened so that the user may enter the facility.
