摘要： Provided is a method of determining a concentration (Ca) of a first analyte (a) in sweat excreted by a first sweat gland type at a first skin location (i) having the first sweat gland type and a second sweat gland type. The method comprises measuring a first concentration (I) of the first analyte in sweat excreted at the first skin location and measuring at least one parameter of sweat excreted by the second sweat gland type at a second skin location (ii) having the second sweat gland type but not the first sweat gland type. The at least one parameter is used to determine a dilution factor (II) which quantifies dilution of the first analyte by sweat excreted by the second sweat gland type at the first skin location. This dilution factor (II) is then used to correct the first concentration (I) so as to determine the concentration (Ca). Further provided is an apparatus (100) for determining the concentration (Ca).

摘要： An on-body sensor system (30) comprises at least two skin interface units (32, 34) for coupling signals into and out of the body, with one of the units being for placement at a known location. One unit applies electrical signals to the body and the other senses them at a remote location. By analyzing the sensed signals using a set of pre-determined body-transmission parameters, a position of one of the skin interface units can be determined. This allows accurate placement of one or the units, for instance to allow more accurate monitoring of physiological parameters using the unit. The body transmission parameters can change over time, whereas once the interface units are put in position, their position is stable. Hence the system also includes functionality to re-calibrate the transmission parameters using at least one known stable set of initial positions of the interface units. The re-calibration comprises a process of re-calculating the parameters based on the known positions. These can then be stored and used for future determinations of the position of the one of the skin interface units having a moveable location, for instance in the case that it is re-positioned or replaced.

摘要： An on-body sensing system (30) comprises a plurality of skin interface elements for coupling electrical signals to and from the body. The system is adapted to derive an indication of a position of at least one positionable interface unit (32) based on transmission of signals between the positionable unit and a set of spatially separated reference units (34), the reference units being positioned at a set of known locations on the body. Transmitted signals are sensed at multiple pairs (52) of electrodes on each reference unit and signal characteristics derived for each pair, and based on this a direction of arrival of the signal determined. By collating all of the measured arrival angles, and by reference to a reference dataset containing information indicative of known signal arrival angles when signals are transmitted internally between the reference units themselves, an indication of position of the positionable unit is derived.

摘要： There is provided a wearable device operable to determine an orientation of the wearable device, when placed on a body. The wearable device comprises a plurality of electrode pairs located at different positions. At least two of the plurality of electrode pairs are configured to receive a signal transmitted from a reference device using the body as a transmission medium. The wearable device also comprises a processor configured to determine a property associated with the signal received at the at least two electrode pairs, compare the determined property to a corresponding reference property and determine, from the comparison, whether the wearable device is in the predetermined orientation on the body. The determined property is indicative of an orientation of the wearable device with respect to the reference device and the corresponding reference property is indicative of a predetermined orientation for the wearable device on the body.

摘要： A hair cutting device for cutting hair on a body of a subject includes a light source for generating laser light at one or more specific wavelengths corresponding to wavelengths absorbed by one or more chromophores in hair; and a cutting element that has an optical waveguide that is coupled to the light source to receive laser light. A portion of a side wall of the optical waveguide forms a cutting face for contacting hair where, at least at the cutting face, the optical waveguide has a refractive index that is equal to or lower than the refractive index of hair and higher than the refractive index of skin.

摘要： An intravascular Doppler ultrasonic device comprises a tip region forming a fraction of a catheter body at a distal end thereof and carrying an ultrasound probe. The tip region is bendable in a direction perpendicular to a longitudinal direction. An actuator is provided in the tip region, which is configured to receive actuation drive power provided through the catheter body and to exert to the tip region a bending moment of a controllable amount. An actuation controller is configured to control actuation drive power delivery to the actuator so as to control the amount of the bending moment. A Doppler spectrum analysis unit is configured to receive Doppler spectrum data and to determine from it a Doppler signal quality measure indicative of a signal quality of the Doppler spectrum. The actuation controller is configured to determine the actuation drive power in dependence on the determined Doppler signal quality measure.
