Abstract
A detection system senses the location of a preselected color within one or more monitored zones of a machine tool. If the operator of a machine tool wears a red glove, the system detects the location of the color red and defines various monitored zones through the use of synchronization signals and a time circuit. The system can take action based on the location of the particular monitored zones in which the red glove is sensed. These actions can include the sounding of a horn, the lighting of a light, or the deactivation of the machine tool.
Claims20
A method for sensing a presence of a human body part within a predefined region of a machine tool, comprising the steps of:
- receiving a data signal which comprises one or more sensor values, each of said one or more sensor values being representative of a color of one of a plurality of locations within a viewed area;
- identifying a first monitored zone within said viewed area;
- comparing each of said one or more sensor values within said first monitored zone to a preselected color which is representative of said human body part;
- and
- responding to said preselected color being generally equal to one of said one or more sensor values within said first monitored zone by taking a first predetermined action.
A method for detecting a presence of a human body part within a predefined region of a machine tool, comprising the steps of:
- receiving a signal which comprises one or more magnitudes, each of said one or more magnitudes being representative of a color of one of a plurality of locations within a viewed area;
- identifying a first zone within said viewed area;
- comparing each of said one or more magnitudes within said first zone to a preselected color which is representative of said human body part;
- identifying the presence of at least one of said one or more magnitudes within said first zone as being generally equal to said preselected color;
- and
- responding to said presence with a first predetermined action.
A method for detecting a presence of a human body part within a predefined region of a machine tool, comprising the steps of:
- receiving a video signal from a color camera, said video signal comprising one or more sensor values which represents a color of a plurality of locations within a viewed area;
- detecting the presence of a preselected color within a first monitored zone within said viewed area;
- and
- responding to the detection of said preselected color within said first monitored zone by taking a first predetermined action, said preselected color being representative of said human body part.
