Abstract: Embodiments of the present disclosure provide a surgical robot system may include an end-effector element configured for controlled movement and positioning and tracking of surgical instruments and objects relative to an image of a patient's anatomical structure. In some embodiments the end-effector may be tracked by surgical robot system and displayed to a user. In some embodiments the end-effector element may be configured to restrict the movement of an instrument assembly in a guide tube. In some embodiments, the end-effector may contain structures to allow for magnetic coupling to a robot arm and/or wireless powering of the end-effector element. In some embodiments, tracking of a target anatomical structure and objects, both in a navigation space and an image space, may be provided by a dynamic reference base located at a position away from the target anatomical structure.

Abstract: A coupon generator system according to the present invention may include a coupon generator, a database, a calendar generator, and a flash coupon generator. The coupon generator may be configured to receive coupon information from a user and generate coupon images and information regarding coupons. The database may be configured to receive images and information from the coupon generator and provide access to the data to other components of the system. The calendar generator may be configured to draw information and images from the database and generate a publicly-accessible calendar with coupons. The flash coupon generator may be configured to draw information from the database and generate flash coupon files for print media. Preferably, the system comprises a web server coupled to the Internet. The system may further include an on-line community calendar configured to receive content from the calendar generator.

Abstract: A device for moving an object relative to a surface, for example for pushing a bar in a bar feed mechanism, comprises a piston mounted for reciprocation within a chamber (2), and a piston rod (8) extending from one end of the chamber. Front and rear locking devices (12, 10) respectively associated with the piston rod (8) and chamber (2) are activated alternately in synchronism with the movement of the piston in opposite directions respectively in the chamber (2).
