Abstract

An electroshock device for delivering an electrical discharge to a target includes an electrical discharge circuit, an electrode coupled to the electrical discharge circuit and having an attachment feature attachable to the target. Upon attachment the electrode is enabled to monitor a physiological condition of the target, generate a signal based on the physiological condition, and deliver the electrical discharge to the target. The electroshock device also includes a controller communicatively coupled to the electrical discharge circuit and the electrode. The controller is configured to modulate delivery of the electrical discharge based on the signal.

First claim

What is claimed is:

1. An electroshock device for delivering an electrical discharge to a target, the electroshock device comprising:
an electrical discharge circuit;

monitor an involuntary muscular condition of the target;
generate a signal based on the involuntary muscular condition; and
deliver the electrical discharge to the target; and

a controller communicatively coupled to the electrical discharge circuit and the one or more electrodes, the controller being configured to determine whether the target is temporarily incapacitated based on the signal, and to modulate at least one of an intensity and a duration of the electrical discharge based on the determination.

2. The electroshock device of claim 1 , wherein at least one of the electrodes is configured to sense the involuntary muscular condition of the target while the electrical discharge is delivered to the target, and wherein the involuntary muscular condition includes an involuntary response of the target to delivery of the electrical discharge.

3. The electroshock device of claim 1 , wherein the controller is configured to determine whether the target is sufficiently subdued based on the signal, and wherein the controller is configured to modulate at least one of an intensity and a duration of the electrical discharge based on the determination.

4. The electroshock device of claim 1 , wherein the controller is configured to modulate a predefined electrical discharge based on the signal prior to allowing the one or more electrodes to deliver the electrical discharge to the target.

5. The electroshock device of claim 1 , wherein the at least one electrode is configured to monitor the involuntary muscular condition of the target by electromyography.

6. The electroshock device of claim 1 , wherein the at least one electrode is further configured to monitor a physiological condition of the target by detection of an electrocardiographic signal.

7. The electroshock device of claim 6 , wherein the controller is configured to detect at least one of heart arrhythmia and heart fibrillation in the target based on the electrocardiographic signal, and wherein the controller is configured to decrease at least one of an intensity and a duration of the electrical discharge based on detecting at least one of heart arrhythmia and heart fibrillation.
