Abstract

The invention includes various electronic devices for avoiding or minimizing XRF analyzer user fatigue. In one embodiment, the XRF analyzer can include a finger tap switch for activating the XRF analysis. In another embodiment, the XRF analyzer can include a hand sensor and a finger tap switch, activation of both required to activate the XRF analysis. In another embodiment, the XRF analyzer can include a microphone capable of receiving a verbal command from a user and a finger tap switch, both receipt of the verbal command and activation of the finger tap switch required to activate the XRF analysis. Additional benefits of some embodiments include improving XRF analysis safety and avoiding XRF analyzer theft.

First claim

What is claimed is:

1. An x-ray fluorescence (XRF) analyzer comprising:
a) an x-ray source configured to emit x-rays towards a sample and an x-ray detector configured to receive fluoresced x-rays emitted from the sample;
b) an activation switch electrically coupled to an electronic processor and operable to activate an XRF analysis, the XRF analysis including:
i) the x-ray source emitting the x-rays towards the sample;
ii) the x-ray detector receiving the fluoresced x-rays emitted from the sample; and
iii) analysis of the fluoresced x-rays; and

c) the activation switch including a finger tap switch configured to activate the XRF analysis by a tap from a finger of a user on the finger tap switch, the finger tap switch having a required duration of less than three seconds.

2. The XRF analyzer of claim 1 , wherein:
a) the activation switch further comprises a microphone configured to receive a verbal command from a user; and
b) the activation switch is configured to activate the XRF analysis upon receipt of both the verbal command and the tap from the finger of the user on the finger tap switch.

3. The XRF analyzer of claim 2 , wherein a password, voice recognition, or both, in the verbal command to the microphone, is required for activation of the XRF analysis.

4. The XRF analyzer of claim 2 , wherein the XRF analyzer is configured for a verbal command from the user into the microphone to stop the XRF analysis.

5. The XRF analyzer of claim 1 , wherein the finger tap switch has a required duration of less than one second.

6. The XRF analyzer of claim 1 , wherein the finger tap switch has a required duration of less than 0.25 seconds.

7. The XRF analyzer of claim 1 , wherein the finger tap switch is configured to activate the XRF analysis by multiple taps and each tap has a required duration of less than one second.

8. The XRF analyzer of claim 1 , wherein the finger tap switch is configured to activate the XRF analysis by multiple taps and each tap has a required duration of less than 0.25 seconds.

9. The XRF analyzer of claim 1 , further comprising a speaker electrically coupled to the electronic processor, and wherein the speaker is configured to notify the user upon activation of the XRF analysis.

10. The XRF analyzer of claim 1 , further comprising a kill switch located at an exterior of the XRF analyzer spaced apart and separate from the finger tap switch, electrically coupled to the electronic processor, and configured to terminate the XRF analysis when pressed.

11. The XRF analyzer of claim 1 , further comprising a hand sensor, and wherein:
a) the hand sensor is located at a handle of the XRF analyzer and spaced apart from the finger tap switch;
b) the hand sensor comprises a temperature sensor, a photo sensor, a pressure sensor, a capacitive sensor, or combinations thereof;
c) the activation switch is configured to activate the XRF analysis only upon:
i) the tap from the finger of the user on the finger tap switch; and
ii) the hand sensor sensing a hand of the user.

12. The XRF analyzer of claim 11 , wherein the hand sensor comprises
the temperature sensor, the photo sensor, the capacitive sensor, or combinations thereof.

13. An x-ray fluorescence (XRF) analyzer comprising:
a) an x-ray source configured to emit x-rays towards a sample and an x-ray detector configured to receive fluoresced x-rays emitted from the sample;
b) an activation switch electrically coupled to an electronic processor and operable to activate an XRF analysis, the XRF analysis including:
i) the x-ray source emitting the x-rays towards the sample;
ii) the x-ray detector receiving the fluoresced x-rays emitted from the sample; and
iii) analysis of the fluoresced x-rays; and

c) the activation switch including a microphone configured to receive a verbal command from a user and a finger tap switch, the activation switch configured to activate the XRF analysis upon receipt of both the verbal command and a tap from the finger of the user on the finger tap switch.

14. The XRF analyzer of claim 13 , wherein a password, voice recognition, or both, in the verbal command to the microphone, is required for activation of the XRF analysis.

15. The XRF analyzer of claim 13 , wherein the XRF analyzer is configured for a verbal command from the user into the microphone to stop the XRF analysis.

16. The XRF analyzer of claim 13 , further comprising a speaker electrically coupled to the electronic processor, and wherein the speaker is configured to notify the user upon activation of the XRF analysis.

17. The XRF analyzer of claim 13 , wherein the finger tap switch has a required duration of less than one second.

18. An x-ray fluorescence (XRF) analyzer comprising:
a) an x-ray source configured to emit x-rays towards a sample and an x-ray detector configured to receive fluoresced x-rays emitted from the sample;
b) an activation switch electrically coupled to an electronic processor and operable to activate an XRF analysis, the XRF analysis including:
i) the x-ray source emitting the x-rays towards the sample;
ii) the x-ray detector receiving the fluoresced x-rays emitted from the sample; and
iii) analysis of the fluoresced x-rays; and

c) the activation switch including:
i) a finger tap switch; and
ii) a hand sensor located at a handle of the XRF analyzer and spaced apart from the finger tap switch,

d) the activation switch is configured to activate the XRF analysis upon both a tap from a finger of a user on the finger tap switch and the hand sensor sensing a hand of the user.

19. The XRF analyzer of claim 18 , wherein the hand sensor comprises a temperature sensor, a photo sensor, a pressure sensor, a capacitive sensor, or combinations thereof.

20. The XRF analyzer of claim 18 , wherein the finger tap switch has a required duration of less than one second.
