Abstract

A system for detecting foreign materials comprising an alternative light source (ALS), one or more filters operationally associated with the ALS, one or more camera lenses operationally associated with the ALS and the filters, one or more processors, a computer readable memory, and a computer readable storage medium operatively associated with a computing device operatively associated with the ALS, one or more sensors operationally associated with the computing device and the ALS, wherein the sensors detect the presence of the filter and a camera operationally associated with the lens and the computing device.

Claims (52)

1. A system for detecting foreign materials comprising:

an alternative light source (ALS);

one or more filters operationally associated with the ALS;

one or more cameras and camera lenses operationally associated with the ALS and the filters;

one or more processors, a computer readable memory, and a computer readable storage medium operatively associated with a computing device operatively associated with the ALS and the camera;

one or more sensors operationally associated with the computing device and the ALS, and camera, wherein the sensors detect the presence of the filter;

a filter holder operationally associated with the ALS and the filter; and

a lens step ring including one or more magnets operationally associated with the ALS and the filter;

wherein the lens step ring releasably secures the filter to the ALS;

wherein the one or more sensors detects the presence of the one or more filters when they are secured to the filter holder; and

wherein the sensor activates programming instructions to change the wavelength of light generated by the ALS based on the filter detected.

2. The system of claim 1 further comprising:

programming instructions to select one or more wavelengths of light to emit from the ALS.

3. The system of claim 1 further comprising:

programming instructions to configure the ALS and the camera based on available light and filters; and

programming instructions to capture one or more images of a subject being photographed.

4. The system of claim 1 further comprising:

one or more rings of lights surrounding an opening through the ALS, the lights being operationally associated with the computing device.

5. The system of claim 1 wherein the ALS can emit light in wavelengths including white (400-700 nm), ultraviolet (350-380 nm), violet (400-430 nm), blue (420-470 nm), blue/green (445-510 nm), green (480-560 nm), orange (570-610 nm), red (610-660 nm) and/or infrared (800-900 nm).

6. The system of claim 1 wherein the filter is selected from the group including: orange, yellow, red, or any combination thereof.

7. The system of claim 1 wherein the ALS and the camera communicate with the computing device by wire, wirelessly, or a combination thereof.

8. A method for detecting foreign materials comprising the steps of:

a) providing a system for detecting foreign materials comprising:

an alternative light source (ALS);

one or more filters operationally associated with the ALS;

one or more camera lenses operationally associated with the ALS and the filters;

one or more processors, a computer readable memory, and a computer readable storage medium operatively associated with a computing device operatively associated with the ALS;

one or more sensors operationally associated with the computing device and the ALS, wherein the sensors detect the presence of the filter;

a filter holder operationally associated with the ALS and the filter; and

a lens step ring including one or more magnets operationally associated with the ALS and the filter;

wherein the lens step ring releasably secures the filter to the ALS;

wherein the one or more sensors detects the presence of the one or more filters when they are secured to the filter holder; and

wherein the sensor activates programming instructions to change the wavelength of light generated by the ALS based on the filter detected:

a camera operationally associated with the lens and the computing device;

b) activating white light LEDS on the ALS;

c) securing one or more filter to the ALS;

d) detecting the presence of the filter using the one or more sensors;

e) deactivating the white light LEDs on the ALS;

f) activating blue light LEDS on the ALS;

g) directing light from the ALS onto a subject or object being examined;

h) locating the foreign materials on the subject or object being examined; and

i) capturing one or more images of the foreign materials with the camera.

9. The method of claim 8 further comprising:

programming instructions to select one or more wavelengths of light to emit from the ALS.

10. The method of claim 8 further comprising:

programming instructions to configure the ALS and the camera based on available light and filters; and

programming instructions to capture one or more images of a subject being photographed.

11. The method of claim 8 further comprising:

one or more rings of lights surrounding an opening through the ALS, the lights being operationally associated with the computing device.

12. The method of claim 8 wherein the ALS can emit light in wavelengths including white (400-700 nm), ultraviolet (350-380 nm), violet (400-430 nm), blue (420-470 nm), blue/green (445-510 nm), green (480-560 nm), orange (570-610 nm), red (610-660 nm) and/or infrared (800-900 nm).

13. The method of claim 8 wherein the filter is selected from the group including: orange, yellow, red, or any combination thereof.

14. The method of claim 8 wherein the ALS and the camera communicate with the computing device by wire, wirelessly, or a combination thereof.
