Abstract
A transmitter is provided by the present application. The transmitter comprises a first element, configured to receive signal with a first frequency group, wherein first impedance value of the first element is changed according to a force, a second element with a second frequency group, and a tip section, configured to receive outputs of the first and the second elements and to transmit an electric signal, wherein the tip section is used to receive the force.
Claims30
An active transmitter, comprising:
- a battery for providing power;
- a first signal source for providing a first frequency group;
- a second signal source for providing a second frequency group, wherein the second signal source is independent from the first signal source, wherein the first signal source and the second signal source are powered by the battery;
- a first element, configured to receive signals with the first frequency group from the first signal source, wherein a first impedance of the first element changes according to a pressure;
- a second element, configured to receive signals with the second frequency group from the second signal source, wherein the second element has a second impedance;
- and
- a tip section, configured to receive outputs of the first element and the second element and output an electric signal, wherein the tip section is used to receive the pressure;
- wherein the second impedance does not change according to the pressure.
A method for controlling an active transmitter, wherein the transmitter comprises a battery for providing power, a first signal source, a second signal source independent from the first signal source, a first element, a second element, and a tip section, the tip section is configured to receive outputs of the first element and the second element, the method comprising:
- changing a first impedance of the first element according to a pressure received by the tip section;
- providing signals with a first frequency group from the first signal source to the first element;
- providing signals with a second frequency group from the second signal source to the second element, wherein the second element has a second impedance, wherein the first signal source and the second signal source are powered by the battery, the second impedance does not change according to the pressure;
- and
- transmitting an electric signal via the tip section.
