Abstract:
1. An interface between a surgeon and an automated assistant, comprising: a. at least one array comprising N RF transmitters, where N is a positive integer; b. one RF receiver provided with at least two co-located directional antenna; each of which is adapted to transmit a signal; each of said co-located directional antenna is characterized by an antenna Gain, Gr; each two co-located directional antenna are characterized by a predetermined dependency of the gain's ratio as a function of the direction from which said signal has been sent; c. means for attaching said RF transmitter array to at least one surgical tool; and, d. a computerized operating system adapted to record the received signal strength (RSS) received by each of said directional antenna of said one RF receiver; said interface is characterized by calculating the angle from which a signal had been received, by comparing said RSS received from all of said directional antenna in said RF receiver and the antenna's gain of each of said directional antenna according to the following equation RSS(directional antenna
