  An example of sensor circuit 1310, first target state identification circuit 1500, and first target state identification circuit 1700 will be discussed below.

  The sensor circuit 1310, the first target state identification circuit 1500, the first target state identification circuit 1700, and the third target state identification circuit 1900 are, for example, an astable oscillator circuit (or more specifically, a capacitive sensing circuit). It may be realized.

  FIG. 3 illustrates an example of an astable oscillator circuit implemented using a 555 timer integrated circuit. The frequency of the astable oscillator output signal is determined when the first component 50 is physically attached to the console 10 via a fixed electrical connection to the reference circuit 1313 (with the reference capacitor 1315) and (i) the intermediate component 30. The selective electrical connection of the first target state identification circuit 1500 (with the first target state capacitor 1510), (ii) when the user activates the second target state switch 1710 (second target state capacitor 1730) And a selective electrical connection of a second target state identification circuit 1700 (with a second target state switch), and (iii) a third target state capacitor 1930 when the user activates the third target state switch 1910 And a selective electrical connection of a third target state identification circuit 1900 (with a third target state switch 1910). It is. The output signal frequency of the astable oscillator is inversely proportional to the capacitance provided by the reference capacitor, the first target capacitor 1510, the second target capacitor 1730, and the third target capacitor 1930.

  In FIG. 3, trigger pin 2 and threshold pin 6 are connected to form a self-trigger, which causes the 555 timer IC to operate as an astable oscillator. Here, the resistor R1 and the resistor R2 function as a timing resistor, and the discharge pin 7 is connected to the junction of the resistor R1 and the resistor R2. When the power supply Vcc is connected, the reference capacitor 1315 and the selectively electrically connected first target capacitor 1510, second target capacitor 1730 and third target capacitor 1930 act like timing capacitors and change toward Vcc. . When one or more capacitors are charged, the output pin 3 remains high. When one or more capacitors are slightly above 2/3 Vcc, the upper comparator of the 555 timer IC starts the operation of the internal control flip-flop, and one or more capacitors are discharged to the ground side through the resistor R2. The power remains low during this discharge cycle. At the time of discharging, as the voltage across one or more capacitors reaches 1/3 Vcc, the operation of the lower comparator is started, charging is started again, and the output is maintained high.

  As additional capacitors are electrically connected, the capacitance provided is increased, thereby reducing the frequency of the unstable oscillator output. Unstable to be used to determine one or more states of the electrical arrangement of the first component based on a predetermined rating of the reference capacitor, the first target capacitor, the second target capacitor, and the third target capacitor The frequency of the oscillator output may be correlated.

In the first arrangement, where the first component is not attached to the console, the reference capacitor 1315 is selected such that the astable oscillator provides a feedback signal having a measurable baseline frequency. In the second arrangement in which the first component 50 is attached to the console 10, the first target state capacitor 1510 is selected such that the astable oscillator provides a feedback signal having a measurable first frequency different from the baseline frequency. In the third arrangement, where the first component 50 is attached to the console 10 and the second target switch 1710 is activated to electrically connect the second target state capacitor 1730, the second target state capacitor 1730 is a base The astable oscillator is selected to provide a feedback signal having a measurable second frequency different from the line frequency and the first frequency. The controller 1370 is configured to determine the capacitance provided by the unstable oscillator, for example, by counting rectangular wave pulses in a predetermined time period. The determined capacitance indicates a state of electrical arrangement of the first component 50 with respect to the console 10. It should be noted that even if the first component 50 is not attached to the console 10 (i.e., even in the first arrangement described above), the surgical system 1 and particularly the circuit 100 may be at a baseline frequency to control the AC signal generator 1103. A reference circuit 1313 having a reference capacitor 1315 is provided in the console 10 so that a feedback signal based thereon is provided to the controller 1370.

  In a variation of the circuit 100 shown in FIG. 3, an astable oscillator circuit configured with a 555 timer IC replaces the reference capacitor 1315 with a reference resistor, and a first target capacitor 1510, a second target state capacitor 1730. And replacing one or more of the third target capacitors with corresponding one or more of the first target resistor, the second target resistor, and the third target resistor.

  FIG. 4 illustrates another example of a reference circuit that implements an astable oscillator circuit and a sensor circuit 1310.

  FIG. 4 shows an unstable oscillator as a relaxation oscillator. The comparator captures and compares the reference voltage from the voltage divider and the device status signal, sends an output to a reset type latch circuit that provides feedback to the comparator, and provides the feedback signal to the controller. The reset type latch circuit includes a Schmitt trigger that provides hysteresis and a transistor switch that resets oscillation.

  The sensor circuit 1310, the first target state identification circuit 1500, the first target state identification circuit 1700, and the third target state identification circuit 1900 may be realized by, for example, a voltage sensor as illustrated in FIG.

  FIG. 5 shows a device status signal sensing circuit for DC, time invariant signals. The power supply voltage is supplied by the power supply Vcc through the pull-up resistor 511 on the bus 106 to the reference resistor 1510 and one or more standard resistors. The device status signal voltage on bus 106 is compared by device 522 to a reference voltage supplied by a voltage divider consisting of resistors 501 and 502. The stability of this comparison is provided by feedback resistor 520. The output of the comparator 522 is supplied to the analog-digital converter 521, and a feedback signal is generated.
