System and method for auto triggering of a data acquisition device
View Patent ↗A data acquisition device for an auto triggering thereof includes a movement detector, a distance detector, a processor, and a data acquiring component. The movement detector detects movement data of the data acquisition device. The movement data indicates a state of movement for the data acquisition device. The state of movement is one of static and dynamic. The distance detector detects distance data between the data acquisition device and an object to which data is to be acquired. The processor receives the movement data to determine the state of movement and, when the state of movement is determined to be static, receives the distance data to determine the distance of the object from the data acquisition device. The data acquiring component acquires the data from the object when the processor initially determines that the state of movement is static and subsequently determines the distance is within a predetermined range.
1. A data acquisition device, comprising:
a movement detector detecting a state of movement of the data acquisition device and generating movement data indicative of the state of movement of the data acquisition device, the state of movement being one of static and dynamic;
a distance detector generating distance data indicative of a distance between the data acquisition device and an object to which data is to be acquired;
a processor receiving the movement data to determine the state of movement and, when the state of movement is determined to be static, receiving the distance data to determine the distance of the object from the data acquisition device; and
a data acquiring component triggered by the processor to automatically acquire the data from the object when the processor initially determines that the state of movement is static and subsequently determines the distance of the object from the data acquisition device is within a predetermined range.
2. The data acquisition device of claim 1 , wherein the movement detector is an accelerometer.
3. The data acquisition device of claim 2 , wherein the accelerometer generates the movement data for the data acquisition device in three dimensions.
4. The data acquisition device of claim 3 , wherein the movement data being substantially constant determines whether the data acquisition device is static.
5. The data acquisition device of claim 3 , wherein the state of movement is changed from static to dynamic if at least one of the movement data is greater than a first threshold value.
6. The data acquisition device of claim 3 , wherein the state of movement is changed from dynamic to static if all of the movement data is less than a second threshold value.
7. The data acquisition device of claim 1 , wherein the distance detector is an infrared (IR) component comprising a transmitter and a receiver.
8. The data acquisition device of claim 1 , wherein the predetermined range sets a minimum and a maximum range in which the data acquisition device is capable of acquiring the data from the object.
9. The data acquisition device of claim 1 , wherein the acquiring of the data is performed automatically as a function of the distance.
10. The data acquisition device of claim 1 , wherein only the state of movement is determined if the state of movement is dynamic.
11. A method, comprising:
determining a state of movement of a data acquisition device with a movement detector coupled to the data acquisition device, the state of movement being one of static and dynamic;
when the determined state of movement of the data acquisition device is static, determining a distance of the data acquisition device from an object from which data is to be acquired with a distance detector; and
when the determined distance is within a predetermined range, automatically acquiring data from the object with the data acquisition device.
12. The method of claim 11 , wherein the state of movement is determined by an accelerometer.
13. The method of claim 12 , further comprising:
generating movement data by the accelerometer for the data acquisition device in three dimensions.
14. The method of claim 13 , further comprising:
changing the state of movement from static to dynamic if at least one of the movement data is greater than a first threshold value.
15. The method of claim 13 , further comprising:
changing the state of movement from dynamic to static if all of the movement data is less than a second threshold value.
16. The method of claim 11 , wherein the distance is determined by an IR component comprising a transmitter and a receiver.
17. The method of claim 11 , wherein the predetermined range sets a minimum and a maximum range in which the data acquisition device is capable of acquiring the data from the object.
18. The method of claim 11 , wherein the acquiring of the data is performed automatically as a function of the distance.
19. The method of claim 11 , wherein only the state of movement is determined if the state of movement is dynamic.
