Tile feeding driving mechanisms, tile feeding assemblies and mahjong machine

The invention discloses tile feeding driving mechanisms, tile feeding assemblies and a mahjong machine. Each tile feeding driving mechanism of the mahjong machine comprises a tile feeding support, a tile storage groove, a tile feeding guide rail, a tile feeding pushing head and a steel wire rope, rolling parts are arranged at the position, close to the corresponding tile feeding guide rail and/or the corresponding tile storage groove, of each steel wire rope, each rolling part is installed on the corresponding tile feeding guide rail or the corresponding tile feeding support in a rotatable mode, the part, located in the corresponding tile storage groove, of each steel wire rope are in rolling contact with the multiple rolling parts, and a gap is maintained between the part, located in the corresponding tile storage groove, of each steel wire rope and the corresponding tile feeding guide rail and/or the side wall of the corresponding tile storage groove. According to the scheme, sliding friction of steel wire ropes in the prior art is replaced with rolling friction of the steel wire ropes, friction resistance in the operation process of the steel wire ropes is greatly decreased, and the situation that the service life and operation stability of the steel wire ropes are influenced due to sliding friction contact between the part, located in the corresponding tile storage groove, of each steel wire rope and the corresponding tile feeding guide rail and/or the arc-shaped bent side wall of the corresponding tile storage groove is avoided.

Tracking and gesture recognition system particularly suited to vehicular control applications

A system and method tracks the movements of a driver or passenger in a vehicle (ground, water, air, or other) and controls devices in accordance with position, motion, and/or body or hand gestures or movements. According to one embodiment, an operator or passenger uses the invention to control comfort or entertainment features such the heater, air conditioner, lights, mirror positions or the radio/CD player using hand gestures. An alternative embodiment facilitates the automatic adjustment of car seating restraints based on head position. Yet another embodiment is used to determine when to fire an airbag (and at what velocity or orientation) based on the position of a person in a vehicle seat. The invention may also be used to control systems outside of the vehicle. The on-board sensor system would be used to track the driver or passenger, but when the algorithms produce a command for a desired response, that response (or just position and gesture information) could be transmitted via various methods (wireless, light, whatever) to other systems outside the vehicle to control devices located outside the vehicle. For example, this would allow a person to use gestures inside the car to interact with a kiosk located outside of the car.
