Abstract: A wearable device is provided. The wearable device includes a housing. The housing includes a housing base, a housing hook extending from the housing base, and a locking pin extending from the housing base. The wearable device also includes a cover. The cover includes a cover base having an opening to receive the locking pin and a cover hook extending from the cover base. The cover hook is configured to engage the housing hook for latching the cover onto the housing. The wearable device also includes a strap. The strap includes a connector that has a through hole to receive the locking pin securing the strap to the housing and the cover when the housing and the cover are latched.

Abstract: Methods for providing a bioimpedance measurement based interface for controlling a wearable device are provided. An example wearable device includes a strap configured to be worn by a user, an outer electrode located on the outer side of the strap, an inner electrode located on the inner side of the strap and configured to be in permanent contact with the skin of the user, a bioimpedance measurement module configured to measure a differential voltage between the outer electrode and the inner electrode and determine, based on the differential voltage, a bioimpedance signal of the user, and a microcontroller configured to determine that the bioimpedance signal is within a predetermined range, in response to the determination, analyze the bioimpedance signal to determine a pattern of touching the outer electrode by the user, determine that the pattern matches a predetermined pattern, and execute an operation corresponding to the predetermined pattern.

Abstract: Systems and methods for performing combined inter-device multi-point bioimpedance measurements are provided. An example system includes a first device and a second device.

The controller can provide an electrical current to electrodes of the first subset and measure voltages from the electrodes of the second subset to determine bioimpedance parameters of the human body.

Abstract: Systems and methods for bioimpedance measurement are provided. An example system includes a strap for carrying a smart watch on a wrist of a user, a bioimpedance measurement module, and an acoustic generator embedded into the strap. The bioimpedance measurement module is configured to measure an impedance of a tissue of the user. The acoustic generator is further configured to generate an acoustic signal modulated to carry data including the impedance. The acoustic signal can be sensed by an acoustic sensor of the smart watch. The smart watch may include an application for sensing the acoustic signal and for converting the sensed acoustic signal into a value for the impedance.

Abstract: Provided is a tracking device. The tracking device may include an internal sensor, a receiver, and a controller. The receiver may include a first electrical contact and a second electrical contact each configured to receive an electrical signal from an external device. The controller may be configured to analyze a first electrical signal from the internal sensor to determine first data. The controller may be configured to detect a presence of a second electrical signal in the first electrical contact and the second electrical contact and, identify the external device based on a portion of the second electrical signal and analyze, based on the result of the identification, the electrical signal to determine second data. The controller can perform combined analysis of the first data and the second data to determine an additional value of physiological parameters of a user, behavioral parameters of the user, or environmental parameters.
