Abstract

Handheld weapons using tactile feedback to deliver silent status information are described. One embodiment comprises a handheld weapon comprising: a housing comprising a user contactable region, a tactile element coupled to the user contactable region, and an actuator coupled to the tactile element and capable of outputting a haptic sensation localized to the tactile element.

First claim

That which is claimed is:

1. A handheld device comprising:
a user graspable housing comprising a user contactable region;
a tactile element coupled to the user contactable region;
a fingerprint sensor configured to detect a fingerprint and transmit a first signal associated with the fingerprint;
a sensor configured to detect data and transmit a second signal associated with the data, wherein the sensor comprises a magnetic detector;
a processor coupled to the fingerprint sensor and the sensor, the processor configured to:
receive the first signal from the fingerprint sensor;
receive the second signal from the sensor;
determine whether a user is a known user based in part on the first signal;
determine a haptic signal based in part on the first signal and the second signal; and

an actuator assembly positioned within the housing and coupled to the tactile element, the actuator assembly configured to receive the haptic signal and output a silent haptic sensation localized to the tactile element, the actuator assembly comprising a piezoelectric transducer, the piezoelectric transducer comprising a metal diaphragm, the metal diaphragm comprising an added mass configured to lower the natural frequency of the diaphragm.

2. The handheld device of claim 1 , wherein the actuator outputs a force to the tactile element to laterally move the tactile element substantially along a plane of a contact surface of the tactile element.

3. The handheld device of claim 1 , wherein the actuator outputs a force to the tactile element to move the tactile element substantially orthogonal to a contact surface of the tactile element.

4. The handheld device of claim 1 , wherein the actuator is a solid state element.

5. The handheld device of claim 4 , wherein the piezoelectric transducer comprises a piezoelectric ceramic transducer.

6. The handheld device of claim 1 , further comprising a driving mechanism that is coupled to the actuator assembly to control a delivery of the haptic sensation.

7. The handheld device of claim 1 , wherein the handheld device comprises a gun or a stun-gun.

8. The handheld device of claim 1 , wherein the user contactable region of the housing is a handle or a grip.

9. The handheld device of claim 1 , wherein the haptic sensation is a controlled pulse.

10. The handheld device of claim 1 , wherein the haptic sensation is a periodic force sensation.

11. The handheld device of claim 10 , wherein the periodic force sensation comprises a sine wave, a square wave, a saw-toothed-up wave, a saw-toothed down wave, or a triangle wave.

12. The handheld device of claim 1 , further comprising a detector coupled to the tactile element that is configured to detect when a user is contacting the tactile element and transmit a third signal to the processor.

13. The handheld device of claim 12 , wherein the processor is further configured to determine the haptic effect based in part on the third signal.

14. The handheld device of claim 1 , wherein the fingerprint sensor comprises a user input device.

15. The handheld device of claim 1 , wherein the haptic effect is a confirmation effect associated with an identification of the user.

16. The handheld device of claim 1 , wherein the sensor comprises a sensor configured to detect a wireless electromagnetic signal.

17. The handheld device of claim 1 , wherein the sensor comprises a bar code scanner.

18. The handheld device of claim 1 , wherein the silent haptic sensation comprises a frequency of less than 500 Hz.

19. A handheld device comprising:
a user graspable housing comprising a user contactable region;
a tactile element coupled to the user contactable region;
a fingerprint sensor configured to detect a fingerprint and transmit a first signal associated with the fingerprint;
a sensor configured to detect data and transmit a second signal associated with the data, wherein the sensor comprises a bar code scanner;
a processor coupled to the fingerprint sensor and the sensor, the processor configured to:
receive the first signal from the fingerprint sensor;
receive the second signal from the sensor;
determine whether a user is a known user based in part on the first signal;
determine a haptic signal based in part on the first signal and the second signal; and

an actuator assembly positioned within the housing and coupled to the tactile element, the actuator assembly configured to receive the haptic signal and output a silent haptic sensation localized to the tactile element, the actuator assembly comprising a piezoelectric transducer, the piezoelectric transducer comprising a metal diaphragm, the metal diaphragm comprising an added mass configured to lower the natural frequency of the diaphragm.
