Drowsy driving alarm system
View Patent ↗A drowsy driving alarm system includes a monitoring mechanism with a camera and an indicator mechanism carrying drowsy driving software and a processor to process data received from the camera regarding drowsiness of a user of the drowsy driving alarm system. The monitoring mechanism can include at least one power source, at least one interface connection, at least one speaker, and a communication bus communicatively interconnecting elements of the monitoring mechanism. The monitoring mechanism can include at least one visual, audible, and/or physical indicator, a microphone, a transceiver, an antenna, at least one sensor and a compass. The indicator mechanism can include at least one display, at least one visual indicator, and a communication bus interconnecting elements of the indicator mechanism. The indicator mechanism can include at least one power source, and at least one interface connection. The indicator mechanism can include at least one audible and/or physical indicator.
1. A drowsiness alarm system, comprising:
a monitoring mechanism having a camera configured for monitoring a pupil of an eye of a subject in order to produce video data corresponding to an image of the eye, the monitoring mechanism further having a monitor processor and a communication bus connecting the processor to the camera, the monitor processor being configured for converting video data received from the camera into digital pixel data in RGB format; and
an indicator mechanism having a processor configured to process data received from the monitoring mechanism regarding drowsiness of the subject of the drowsiness alarm system, including:
a circuit configured for determining density of black pixels per image frame in the data;
a circuit configured for setting a threshold value of the density of black pixels per image frame in a selectable number of consecutive frames to indicate drowsiness;
a circuit configured for turning the indicator mechanism on in order to signal that the subject is drowsy when the determined density of black pixels falls below the threshold value in the selected number of consecutive frames; and
a circuit configured for permitting the subject to programmably set threshold red, green and blue values, digital pixel data falling below the threshold RGB values being counted as a black pixel by the circuit configured for determining density of black pixels per image frame.
2. The drowsiness alarm system according to claim 1 , wherein said camera comprises an analog camera.
3. The drowsiness alarm system according to claim 1 , wherein said camera comprises a digital camera.
4. The drowsiness alarm system according to claim 1 , wherein said monitoring mechanism further comprises at least one indicator selected from the group consisting of a visual indicator, an audio indicator, and a physical indicator, the indicator being connected to said monitor processor by the communication bus, the processor being configured to turn the indicator on to signal the subject when said camera is not focused on the pupil of the subject's eye.
5. The drowsiness alarm system according to claim 1 , wherein said monitoring mechanism further comprises at least one indicator selected from the group consisting of a visual indicator, an audio indicator, and a physical indicator, the indicator being connected to said monitor processor by the communication bus, the processor being configured to turn the indicator on when the determined density of black pixels falls below the threshold value in the selected number of consecutive frames in order to signal that the subject is drowsy.
6. The drowsiness alarm system according to claim 1 , wherein said monitoring mechanism further comprises:
an ear cradle to cradle the ear; and
a longitudinal arm with the camera positioned at an end of the arm, the arm being pivotally attached to the ear cradle to enable the position of the arm to be adjusted.
7. The drowsiness alarm system according to claim 6 , wherein said monitoring mechanism further comprises:
a light source mounted on the camera.
8. The drowsiness alarm system according to claim 6 , wherein said longitudinal arm substantially fixes the camera relative to a position of a pupil of the user's eye.
9. The drowsiness alarm system according to claim 1 , wherein said indicator mechanism is configured to enable monitoring of drowsiness of a user by a third party at a remote location.
10. The drowsiness alarm system according to claim 1 , wherein said indicator mechanism further comprises:
at least one display;
at least one visual indicator; and
a communication bus interconnecting said circuits, the at least one display, and the at least one visual indicator.
11. The drowsiness alarm system according to claim 10 , wherein said indicator mechanism further comprises:
at least one audible indicator connected to the communication bus.
12. The drowsiness alarm system according to claim 10 , wherein said indicator mechanism further comprises:
at least one physical indicator connected to the communication bus.
13. The drowsiness alarm system according to claim 10 , wherein said indicator mechanism further comprises:
at least one power source; and
at least one interface connection, the interface connection being connected to the communication bus.
