RIT MSD P15044 –Intelligent Mobility Cane Infrared Sensitivity 11 Dist B1 [ft] = 8ft Results Angle of the IR Sensor (°) Maximum Sweep Height (in) ***Angle is with respect to the cane. Worst Case Positive with Ideal Angle Worst Case Negative with Ideal Angle Dist B1 [ft] Maximum Sweep Height (in) Dist B1 [ft] = 7ft Results Angle of the IR Sensor (°) Maximum Sweep Height (in) ***Angle is with respect to the cane. Worst Case Positive with Ideal Angle Worst Case Negative with Ideal Angle Dist B1 [ft] Maximum Sweep Height (in) An increase in 2 degrees of the angle of the infrared sensor induces a 1 foot increase in the start of the drop-off detection distance.
