Abstract

Various embodiments of a light detection device and a method of using the device are disclosed. In one or more embodiments, the light detection device can include a housing that extends along a housing axis between top and bottom surfaces. The device can also include a port that is adapted to receive a sample, and a door connected to the housing. The door can include an actuator portion adapted to selectively move the door between a closed position and an open position, and a cover portion connected to the actuator portion and adapted to close the port when the door is in the closed position and open the port when the door is in the open position to allow external access to the port.

First claim

What is claimed is:

1. A light detection device, comprising:
a housing comprising a top surface and a bottom surface, wherein the housing extends along a housing axis between the top surface and the bottom surface, wherein the housing further comprises a handle portion disposed between the top surface and the bottom surface;
a port formed in the top surface of the housing, wherein the port is adapted to receive a sample; and
a door connected to the housing, the door comprising:
an actuator portion adapted to selectively move the door between a closed position and an open position; and
a cover portion connected to the actuator portion and adapted to close the port when the door is in the closed position and open the port when the door is in the open position to allow external access to the port;

wherein the light detection device is adapted to allow a user to grasp the handle portion with a hand and, with the same hand, engage the actuator portion to selectively move the door between the closed position and the open position; and
further comprising a latch attached to the housing and adapted to hold the door in the open position, wherein the latch is further adapted to release the door when the user engages the actuator portion to move the door from the open position to the closed position;
wherein the latch is further adapted to release the door when the user engages the actuator portion to move the door from the open position to the closed position; and wherein the light detection device is a luminometer, photometer, turbidimeter, colorimeter, or fluorometer.

2. The light detection device of claim 1 , wherein the door is connected to the housing by a hinge, wherein the actuator portion is adapted to selectively move the door by rotating the door between the closed position and the open position.

3. The light detection device of claim 1 , wherein the door is biased in the closed position.

4. The light detection device of claim 1 , further comprising a spring disposed between the door and the housing that is adapted to bias the door in the closed position.

5. The light detection device of claim 2 , further comprising a spring disposed between the door and the housing that is adapted to bias the door in the closed position.

6. The light detection device of claim 1 , wherein the housing further comprises a ledge that surrounds at least a portion of the port, wherein the cover portion of the door is adapted to engage the ledge when the door is in the closed position; and wherein the housing further comprises a gasket disposed along at least a portion of the ledge, wherein the gasket is adapted to prevent moisture and ambient light from entering the port.

7. The light detection device of claim 4 , wherein the door is connected to the housing by a hinge, wherein the actuator portion is adapted to selectively move the door by rotating the door between the closed position and the open position.

8. A light detection device, comprising:
a housing comprising a top surface and a bottom surface, wherein the housing extends along a housing axis between the top surface and the bottom surface, wherein the housing further comprises a handle portion disposed between the top surface and the bottom surface;
a port formed in the top surface of the housing, wherein the port is adapted to receive a sample; and
a door connected to the housing, the door comprising:
an actuator portion adapted to selectively move the door between a closed position and an open position; and
a cover portion connected to the actuator portion and adapted to close the port when the door is in the closed position and open the port when the door is in the open position to allow external access to the port;

wherein the light detection device is adapted to allow a user to grasp the handle portion with a hand and, with the same hand, engage the actuator portion to selectively move the door between the closed position and the open position;
wherein the housing further comprises a ledge that surrounds at least a portion of the port, wherein the cover portion of the door is adapted to engage the ledge when the door is in the closed position; and wherein the housing further comprises a gasket disposed along at least a portion of the ledge, wherein the gasket is adapted to prevent moisture and ambient light from entering the port; and wherein the light detection device is a luminometer, photometer, turbidimeter, colorimeter, or fluorometer.

9. The light detection device of claim 8 , wherein the door is connected to the housing by a hinge, wherein the actuator portion is adapted to selectively move the door by rotating the door between the closed position and the open position.

10. The light detection device of claim 8 , wherein the door is biased in the closed position.

11. The light detection device of claim 8 , further comprising a spring disposed between the door and the housing that is adapted to bias the door in the closed position.

12. The light detection device of claim 9 , further comprising a spring disposed between the door and the housing that is adapted to bias the door in the closed position.

13. The light detection device of claim 8 , further comprising a latch attached to the housing and adapted to hold the door in the open position, wherein the latch is further adapted to release the door when the user engages the actuator portion to move the door from the open position to the closed position.

14. A method, comprising:
grasping a handle portion of a housing of a light detection device, wherein the light detection device further comprises a top surface, a bottom surface, and a port formed in the top surface, wherein the handle portion is disposed between the top surface and the bottom surface;
engaging an actuator portion of a door connected to the housing to move the door from a closed position to an open position, wherein the door further comprises a cover portion connected to the actuator portion that is adapted to close the port when the door is in the closed position and to open the port when the door is in the open position to allow external access to the port;
disposing a sample within the housing through the port; and
engaging the actuator portion of the door to move the door from the open position to the closed position;
and wherein the method further comprises
pressing the actuator portion with a finger or thumb of a hand that is grasping the handle portion of the housing to move the door from the closed position to the open position, or
maintaining a force on the actuator portion of the door to keep the door in the open position while the sample is being disposed within the housing, or measuring a characteristic of the sample after the door has been moved from the open position to the closed position, or
more than one of the foregoing; and

wherein the light detection device is a luminometer, photometer, turbidimeter, colorimeter, or fluorometer.

15. The method of claim 14 , comprising pressing the actuator portion with a finger or thumb of a hand that is grasping the handle portion of the housing to move the door from the closed position to the open position.

16. The method of claim 14 , the method comprising maintaining a force on the actuator portion of the door to keep the door in the open position while the sample is being disposed within the housing.

17. The method of claim 14 , wherein engaging the actuator portion of the door to move the door from the open position to the closed position comprises releasing the actuator portion of the door to move the door from the open position
