According to an aspect, there is provided a personal care device () for performing a light-based hair removal or photo-epilation operation on a body of a subject. The personal care device () comprises a housing () that includes a first window or opening (), a light source configured to generate light to perform the light-based hair removal or photo-epilation operation, wherein the light source is arranged in the housing such that light emitted by the light source illuminates a part of the body, a receiving member in or on the housing () for receiving and retaining a consumer electronic device () in or on the personal care device (), and an optical system () in the housing () for enabling an imaging unit () of a consumer electronic device () retained in the recess () to obtain images of a part of the body via the first window or opening ().

Personal care device configured to perform a light-based hair removal

A toothbrush () includes a brushhead (), a first force sensor (A) for measuring a first force exerted by the brushhead at a first angle relative to a tooth and a second force sensor (B) for measuring a second force exerted by the brushhead at a second angle relative to the tooth, the second angle being different than the first angle, and a processing unit (). The processing unit is structured to: (i) receive first information indicative of the first force as measured by the first force sensor, (ii) receive second information indicative of the second force as measured by the second force sensor, and (iii) determine information regarding a current brushing angle of the brushhead based on the first information and the second information.

The invention relates to a photoplethysmography (PPG) apparatus (), comprising at least one light source () configured to generate a beam of source light () having a source beam angle () and at least one controllable beam angle adapter () configured to receive a beam-angle control signal () indicative of a modified beam angle () to be set, the beam angle adapter () being further configured to provide the beam of source light () with a modified beam angle () to an external object (). The PPG apparatus () comprises at least one PPG sensor()configured to provide a sensor signal () indicative of source light () scattered by the external object (), and a PPG evaluation and control unit () configured to receive the sensor signal (), to provide the beam-angle control signal () and to provide at its output () an AC signal component of the sensor signal ().

Photoplethysmography apparatus

An oral cleaning system provides motivating feedback to a user before brushing and includes: a power toothbrush (); one or more sensors () on or within the toothbrush; a processor () within the toothbrush configured to process sensor information obtained from the one or more sensors during a first brushing session of a user; and a feedback system () on or within the toothbrush responsive to the processor and configured to communicate brushing information to the user at a time subsequent to the first brushing session but before a second brushing session of the user.

Systems and methods for providing motivation feedback to a user before brushing

An apparatus (') is configured such that passage of a fluid () through an open port of a distal tip (&#x2032;) enables detection of a substance () that may be present on a surface (), e.g., a surface of a tooth, based on measurement of a signal correlating to a substance at least partially obstructing the passage of fluid () through the open port. The apparatus (&#x2032;) includes a proximal pump portion () and at least one distal probe portion () configured to be immersed in another fluid (), e.g., water in toothpaste foam. A corresponding system () includes one or two such apparatuses (). A method of detecting the presence of a substance on a surface includes probing an interaction zone () for at least partial obstruction of flow of the second fluid medium () through a distal probe tip.

Plaque detection using a stream probe

A detection apparatus enables detection of a substance that may be present on the surface based on measurement of a stream probe signal correlating a substance at least partially obstructing the passage of fluid through a stream probe includes a distal optical gum detector transmission portion and a distal optical gum detector reception portion in a position to transmit and to receive, respectively, an optical signal controlled by a controller, enables the controller to determine if an open port of a distal tip of the stream probe is in contact with a substance at least partially obstructing the passage of fluid through the open port and not in contact with the gums of a subject or of a user of the detection apparatus to override false positive signals.

A method of detecting the presence of a substance on a surface includes probing an interaction zone for at least partial obstruction of flow of the fluid through the distal probe tip. The distal probe tip may have a structural configuration for preventing blocking of the open port. The distal probe tip may also have a non-uniform wear profile. The at least one distal probe portion may include two or multiple components to improve performance and reliability.
