A metabolic energy monitoring system having one or more physiological measurement platforms and displays enabling the calculation and display of energy balance, kilocalorie energy expenditure and kilocalorie intake is described. In preferred embodiments, the system utilizes one or more on-body monitoring platforms to enable measurement of change in body composition and kilocalorie energy expenditure over a period of time thereby enabling a comparator to calculate net energy balance over this period of time and to calculate kilocalorie intake over this same period of time. Such data may then be displayed on a display device in wireless communication with the on-body monitoring platform to provide the user of the system with useful information and guidance in weight management applications.

A device including an array of electrodes generates one or more electrical signals from a user, extracts one or more noise signals, and generates one or more de-noised electrical signals upon processing the electrical signal(s) with the noise signal(s). The array of electrodes is coupled to a surface of the device, where the device also includes force sensors in mechanical communication with the surface for detecting user weight and other forces. The device can be configured to generate electrical signals from different subportions of the array of electrodes and to extract noise signals from different subportions of the array of electrodes, where the subportion(s) for electrical signal generation may or may not overlap with the subportion(s) of electrodes for noise signal extraction.

The inventive concept relates to a body composition analysis system. A body composition analysis system according to an embodiment of the inventive concept includes a sinusoidal signal generator, a synchronous detector, and a bioimpedance analyzer. The sinusoidal signal generator converts a digital sinusoidal signal having a target frequency into an analog sinusoidal signal. The synchronous detector extracts a target frequency component of a bioelectrical signal generated in response to an analog sinusoidal signal based on the digital sinusoidal signal. The bioimpedance analyzer calculates the bioimpedance based on the target frequency component of the bioelectrical signal. According to the inventive concept, it is possible to improve the selectivity for extracting the target frequency component of the bioelectrical signal and to reduce the area and variations of characteristics for the implementation of the integrated circuit.

A wrist-worn training computer includes one or more biosensors; a casing; a display lens positioned against the casing to form an interface between the display lens and the casing, and to enclose together with the casing an enclosed space between the casing and the display lens; a first part of an antenna of a satellite navigation receiver disposed within the enclosed space; and a gasket positioned along the interface between the display lens and the casing to seal the enclosed space. The gasket comprises electrically conductive material that forms a second part of the antenna.

The present invention may provide a system for recommending a user-customized beverage through a genetic test, and a method for driving same, the system comprising: a genetic information acquisition unit for acquiring user's genetic information from a result of a user's genetic test; and a beverage recommendation unit for recommending at least one user-customized recommendable beverage on the basis of the genetic information acquired from the genetic information acquisition unit, wherein the system for recommending a user-customized beverage through a genetic test can recommend a customized-beverage to a user by reflecting a genotype through the user's genetic test.

An apparatus for energy expenditure estimation includes a heart rate sensor for producing a heart rate value indicative of a heart rate of an individual, a heat-flux sensor for producing a heat-flux value indicative of a heat-flux flowing through a measurement area on the skin of the individual, and a processing system communicatively connected to the heart rate sensor and the heat-flux sensor. The processing system is configured to produce an estimate of the energy expenditure based on the heart rate value and the heat-flux value. The use of the heat-flux value improves the accuracy of the estimation especially during low-intensity exercise and rest, when both heart rate and acceleration values often fail to provide information meaningful enough for energy expenditure estimation.

Embodiments of the present disclosure pertain to transmission dielectric probes with at least one channel that extends across the probe. The channel includes a first opening on a first side of the transmission dielectric probe, and a second opening on a second side of the transmission dielectric probe. The first opening and the second opening are on opposite ends of the transmission dielectric probe, and the second opening is associated with an outer surface of the transmission dielectric probe. Additionally, the first opening and the second opening have different diameters, different geometries, or combinations thereof. Further embodiments pertain to methods of operating the transmission dielectric probes by placing the outer surface of the transmission dielectric probe on a surface of an object, transmitting a signal from a first channel through the surface and into the object, and receiving the transmitted signal back through a second channel.
