INFRARED SIGNAL BASED POSITION RECOGNITION SYSTEM FOR USE WITH A ROBOT-ASSISTED SURGERY
First Claim
1. A device for regenerating an infrared signal transmitted over the air for use in detecting a 3-dimensional position of an object, comprising:
- an infrared signal transmitter that transmits an infrared signal over the air towards an object whose position is to be determined;
an infrared signal detector that receives from the object a responsive infrared signal in response to the transmitted infrared signal;
a low pass filter that receives the responsive infrared signal from the detector and outputs a filtered signal; and
a comparator that generates a comparator output representing a logic state based on a first input receiving the responsive infrared signal from the infrared signal detector and a second input receiving the filtered signal from the low pass filter.

Abstract
An improved device for regenerating an infrared signal transmitted over the air for use in detecting a 3-dimensional position of an object. The regeneration device includes an infrared signal transmitter and detector that receives from the object a responsive infrared signal in response to the infrared signal transmitted by the transmitter. A low pass filter receives the responsive infrared signal from the detector and outputs a low-pass filtered signal. A comparator compares the output of the infrared signal detector and output of the low pass filter and generates an output representing a logic state based on the comparison.
