IC DEVICE-IN-POCKET DETECTION WITH ANGULAR MOUNTED LASERS AND A CAMERA

摘要

An apparatus includes a device holder including a device placement area configured to hold an electronic device, and a shoulder extending peripherally around the device placement area; a laser line generator configured to generate a laser line that includes (i) a device placement area laser line portion, and (ii) a shoulder area laser line portion; a camera configured to obtain an image of at least the laser line; and a processor configured to: receive the image from the camera, determine (i) an angle of the device placement area laser line portion, and/or (ii) an offset between the location of the device placement area laser line portion and the location of the shoulder area laser line portion, and determine whether an electronic device is positioned in the device placement area or positioned incorrectly in the device holder.

1. An apparatus comprising:
a device holder comprising a device placement area configured to hold an electronic device, and a shoulder extending peripherally around the device placement area; a laser line generator configured to generate a laser line that includes (i) a device placement area laser line portion extending across at least a portion of the device placement area or at least a portion of an electronic device held in the device placement area, and (ii) a shoulder area laser line portion extending across at least a portion of the shoulder; a camera configured to obtain an image of at least the laser line generated by the laser line generator; and a processor configured to:
receive the image from the camera,determine (i) an angle of the device placement area laser line portion, and/or (ii) an offset between the location of the device placement area laser line portion and the location of the shoulder area laser line portion, anddetermine, based on a comparison between said angle and/or offset and a predetermined normal angle and/or normal offset, at least one of (i) whether an electronic device is positioned in the device placement area, (ii) whether an electrical device is positioned incorrectly in the device holder, (iii) whether two electronic devices are improperly double-stacked in the device holder, and (iv) whether no electronic device is located in the device placement area.
