The invention of claim 1 (equivalent to the claim in China's patent documents) comprises a signal receiving device and a laser pointer, wherein the signal receiving device comprises a receiving processing loop and a camera connected with it, and the laser pointer comprises a head light emitter component and a laser pointer loop. A synchronous signal receiver connected with the receiving processing loop is built in the signal receiving device, and the image sensor in the camera is an image sensor that can be exposed globally. A synchronous signal transmitter corresponding to the synchronous signal receiver is arranged in the laser pointer, and the laser pointer emits light in pulse form. Regarding the electronic whiteboard system of synchronous laser pointer, Compared with Invention 1 (refer to abstract, paragraph numbers [42]-[55]), the light emitting part of the pen tip emits synchronous signals in the infrared band, and it also has a light receiving part, which corresponds to a coordinate detector characterized by a sensing unit that dynamically responds to the synchronous signals.
However, the invention in Claim 1 has slight differences in synchronization methods, and such differences can be easily obtained by ordinary technicians by comparing the structure of sending synchronization signals according to infrared rays on the position detection device side and the structure of emitting light within the time of aligning the synchronization signals under the instruction of the light receiving part in Invention 2. Therefore, the invention of claim 1 is easily invented by ordinary technicians on the basis of comparing the combination of inventions 1 and 2.
the additional structure in the inventions of claims 2 to 4 is the structure related to the synchronous signal transmitter, which is easily obtained from comparing the structure of synchronous signal transmission at the pen tip of invention 1 and the structure of synchronous signal transmission according to infrared rays at the position detection device side of invention 2.
the invention of claim 5 comprises a signal receiving device and a laser pointer, wherein the signal receiving device comprises a receiving processing loop, a camera and a synchronous signal transmitter; the laser pointer comprises a head light emitter component and a laser pointer loop; the camera and the synchronous signal transmitter are both connected with the receiving processing loop; the image sensor in the camera is an image sensor capable of global exposure; A synchronous signal transmitter in the laser pointer is connected with the receiving processing loop, and there is also a synchronous signal receiver corresponding to the synchronous signal transmitter in the laser pointer, and the laser pointer emits light in the form of pulses. As for the electronic whiteboard system of the synchronous laser pointer, compared with the structure of the invention 1 (refer to abstract, paragraph numbers [42]-[55]), the electronic whiteboard system of the synchronous laser pointer is provided with a light receiving part.
However, the invention in Claim 5 has slight differences in synchronization methods, and such differences can be easily obtained by ordinary technicians by comparing the structure of sending synchronization signals according to infrared rays on the position detection device side and the structure of emitting light within the time of aligning the synchronization signals under the instruction of the light receiving part in Invention 2. Therefore, the invention of claim 5 is easily invented by ordinary technicians on the basis of comparing the combination of inventions 1 and 2.
the additional structure in the inventions of claims 6 and 7 is the structure related to the synchronous signal transmitter, which is easily obtained from comparing the synchronous signal transmission structure at the pen tip of Invention 1 and the synchronous signal transmission structure according to infrared rays at the position detection device side of Invention 2.
therefore, the invention of claims 1-7 can be easily invented by comparing the combination of inventions 1 and 2.
generally speaking, the examiner thinks that the application is not creative.
