Abstract

A device including smart sensors with a local signal processor is disclosed. The device includes an end-effector including at least one sensor and a signal processing component corresponding to the at least one sensor; and a handle configured to receive processed information from the signal processing component. The processed information is generated by the signal processing component at the end-effector based on data received from the at least one sensor at the end-effector.

Claims

1. A device comprising:

an end-effector including a first sensor and a signal processing microprocessor corresponding to the first sensor;

a handle including a microcontroller configured to receive processed information from the signal processing microprocessor and control the end-effector based on the processed information; and

a second sensor configured to send second data to the signal processing microprocessor, wherein the second sensor is located at the end-effector, wherein the second sensor is separate from the first sensor,

wherein the signal processing microprocessor is configured to process first data received from the first sensor located at the end-effector locally to generate the processed information to enable the microcontroller in the handle to use the processed information directly without further processing the processed information by the microcontroller in the handle, and

wherein processing, by the signal processing microprocessor, the first data to generate the processed information comprises calibrating, by the signal processing microprocessor, the first data in response to the second data from the second sensor.

2. The device of claim 1, wherein the signal processing microprocessor and the first sensor are part of a single module at the end-effector.

3. The device of claim 1, further comprising:

a shaft configured to communicatively couple the signal processing microprocessor of the end-effector and the handle.

4. The device of claim 1, further comprising a memory in communication with the signal processing microprocessor, wherein the memory is configured to store calculation data that enables the signal processing microprocessor to process the first data received from the first sensor.

5. The device of claim 1, wherein the first sensor comprises a magnetic sensor located at a first jaw member of the end-effector and a second jaw member of the end-effector includes a magnet, and wherein the magnetic sensor is configured to detect changes in a magnetic field caused by a movement of the magnet.

6. The device of claim 1, wherein controlling, by the microcontroller, the end-effector based on the processed information comprises an operation selected from the group consisting of stopping the end-effector, starting the end-effector, and ending a process of the end-effector.

7. A device comprising:

a plurality of smart sensors positioned on an electrical power line located at an end-effector for delivery of electrical power and communicatively coupled to a handle;

a shaft including a return path through which at least one of the plurality of smart sensors and the handle are communicatively coupled; and

a controller at the handle to which at least one of the plurality of smart sensors is commutatively coupled,

wherein at least one of the plurality of smart sensors includes a signal processing microprocessor in the end-effector,

wherein the signal processing microprocessor is configured to process first data received from a first sensor component of at least one of the plurality of smart sensors locally to generate processed information,

wherein the controller is configured to receive the processed information from the signal processing microprocessor and control the end-effector based on the processed information without further processing the processed information by the controller, and

wherein processing, by the signal processing microprocessor, the first data to generate the processed information comprises calibrating, by the signal processing microprocessor, the first data in response to second data from a second sensor component of at least one of the plurality of smart sensors.

8. The device of claim 7, further comprising a memory in communication with the signal processing microprocessor, wherein the memory is configured to store calculation data that enables the signal processing microprocessor to process the first data.

9. The device of claim 7, wherein the first sensor component comprises a magnetic sensor located at a first jaw member of the end-effector and a second jaw member of the end-effector includes a magnet, and wherein the magnetic sensor is configured to detect changes in a magnetic field caused by a movement of the magnet.

10. The device of claim 7, wherein controlling, by the controller, the end-effector based on the processed information comprises an operation selected from the group consisting of stopping the end-effector, starting the end-effector, and ending a process of the end-effector.
