| 摘要 |
The invention pertains to automatic animal actuated apparatus, such as a power operated feeder, wherein an actuator worn by the animal is employed to control light sensing means operatively associated with the servicing apparatus. Interrogation means adjacent an animal station utilizes a plurality of light sensing devices oriented in a predetermined manner to magnetic orientation means. An actuator worn by the animal contains orientation means of a magnetic type for permitting predetermined orientation of the actuator to the interrogation light sensing devices, and a coded light transmitting pattern defined upon the actuator permits interrogation of the actuator by the passage of light therethrough to control the servicing apparatus in the desired manner.
