Disclosed is a method of detecting a smoking behavior based on an acceleration sensor. A method of detecting a smoking behavior based on an acceleration sensor according to an exemplary embodiment of the present disclosure includes: calculating a wrist acceleration variation value which is a variation value of gravitational acceleration applied based on a gravitational direction with respect to a user's wrist in accordance with a motion of the user's wrist by using a three-axis acceleration sensor worn on the user's wrist; converting the wrist acceleration variation value into a wrist angle variation value which is a variation value of a wrist angle that indicates an angle to the user's wrist based on the gravitational direction; comparing at least one template signal made by modeling the variation value of the user's wrist angle corresponding to a smoking behavior with the wrist angle variation value; and detecting the user's smoking behavior based on the comparison result.

Systems and methods are provided for inserting an endoscope through an anatomical cavity to a target site. A speaker is positioned externally proximate to a patient and the endoscope is inserted into the anatomical cavity. A signal is received from at least one sensor positioned near the distal end of the endoscope. The signal is indicative of vibrations induced in internal cavity tissue by the externally positioned speaker. A first anatomical structure in contact with the distal end of the endoscope is identified based on the signal indicative of vibrations induced in the internal cavity tissue by the externally positioned speaker. As the distal end of the endoscope moves from the first anatomical structure into contact with other anatomical structures along a path to the target site, the received signal indicative of induced vibrations changes correspondingly and is used to guide the endoscope to the target site.

Systems and methods for treating and/or averting cardiac arrhythmias, such as atrial fibrillation, are provided. A device comprises a housing including an energy source, a contact surface and an electrode. The energy source is configured to transmit an electrical impulse to the electrode through the outer skin surface to a vagus nerve of the patient. The electrical impulse comprises bursts of about 2 pulses to about 20 pulses with each of the bursts having a frequency of about 3 Hz to about 100 Hz. The electrical impulse modulates the vagus nerve to treat a cardiac arrhythmia of the patient. A system includes a sensor for detecting a physiological parameter of a patient's heart, such as heart rate variability, and a controller configured to activate the stimulator based on the physiological parameter to cause the stimulator to generate the electrical impulse.

A computerized visual orientation surgery assist system and method receives initial anatomic image information of a patient scan, which may be taken at a registration position of the patient; receives initial surgical instrument positional information from a first positional sensor positioned on a surgical instrument, where the positional sensor senses three-dimensional spatial position transmits the surgical instrument positional information; establishes the initial surgical instrument positional information as a surgical instrument origin in three-dimensional space for the initial anatomic image information; displays a visual representation of the initial anatomic image information on a computerized display, the visual representation including a surgical instrument representation based on the initial surgical instrument positional information; receives subsequent surgical instrument positional information from the first sensor associated with movement of the surgical instrument; and updates the computerized display to reflect the subsequent surgical instrument positional information.
