Definitions

  • the present invention relates to an attachment for use with an accelerometer-equipped electronic device, where said attachment utilises the accelerometerof the device to create consumer relevant information; and methods of assessing a surface using the attachment and device.
  • the invention has particular application in the field of smart mobile phones and the field of personal care, particularly in the assessment of static-dynamic friction on hair, skin and teeth.
  • TA PC linked Texture Analyser
  • Devices that can differentiate a variety of properties of surfaces are known. The following are concerned with sensors for assessing the condition of hair and/or skin and converting a signal from the sensor:
  • EP 1 691 195A discloses a hair sensor for detecting a sliding sound of hair to estimate hair characteristics. The sound is transmitted to a microphone.
  • W0 12/020043 discloses apparatus, method and a computer program for evaluating the condition of the skin, scalp and hair. Sensors assess the hair and produce an analog signal which is converted into an audio signal and related to a computer or mobile device.
  • JP 2004-159830 discloses a hair evaluation system comprising a comb or a brush with a microphone attached, which receives the signal of the combing sound, amplifies it and outputs it as sound.
  • US 2003/233861 discloses a method for assessing the friction of hair using a device comprising a comb means and a noise sensor arranged to capture frictional noise generated by passage of comb means through hair.
  • US2015/0342515 discloses a system comprising a hairstyling tool and a remote entity which can be connected to the hairstyling tool by a wireless connection
  • the hairstyling tool is a comb or hairbrush type comprising: a handle and a body, provided with teeth, a battery for storing electricity, at least one movement sensor or accelerometer, an electronic control unit, configured to capture and format signals provided by said sensor, a wireless communication means suitable for data transmission to the remote entity, which is configured to send back information about the hair being styled to the user.
  • Such devices should be capable of measuring a range of properties and of quickly providing information about a range of different consumer related surfaces. . Such devices should provide customisable features that enable the user to tailor the device to give the type of information desired by that individual consumer.
  • the present invention provides the consumer with a personalised measure of properties of surfaces, for example hair, and enables the consumer to track changes in the properties of the surface, via different treatment regimes and product uses, over a period of time.
  • the present invention offers interchangeable probing devices that are capable of making a range of measurements and signals thus providing a diversity not known in the prior art. Because it is so accessible and easy to use, measurements can be performed many times a day, to provide a powerful tool in the hands of the everyday consumer. Thus, the invention provides a means of getting sophisticated infomnation to the consumer about the condition, health and properties of surfaces, thus enabling them to make informed (product) choices for those surfaces.
  • the device of the invention operates as a single unit such that no electronic connection to another device is required.
  • the device that picks up data also analyses it and
  • the device comprises a non-electronic attachment for the generation of vibrations.
  • This invention provides an unexpectedly convenient, flexible and sophisticated tool that does not require additional electronics or power sources over that already present in the hand held electronic device which forms part of the system.
  • the device is used insitu, with no stresses on the surface.
  • an accelerometer provides an accurate measure of small vibrations that are generated when moving a probing device across a surface, such as hair, skin and teeth.
  • the vibrations generated vary according to the nature of the surface.
  • the measurement of the "squeaky clean" state of the surface provides a particular advantage to the user of the device, in the evaluation of the condition of that surface.
  • “Squeaky clean” is a term used by consumers to describe a condition of their hair, skin or teeth. In hair, it is typically evaluated by rubbing the fingers on the surface of the hair, commonly during washing. It can be seen as a positive or negative state, depending on the individual and the characteristics of their hair, both technical (objective) and self- perceived. Some people take a squeaky clean feel as an indication that their hair is really clean and free from oils, grease and silicones, so they are satisfied that their hair is clean. Others take it to mean that their hair is over-cleaned and "stripped” of beneficial materials such as conditioning silicones and "good” oils. When consumers use this as an indication that their hair is dry and lacking moisturisation they will often apply a moisturising or silicone based product.
  • a squeaky clean feel can be taken as an indication that the teeth are properly clean and/or shiny. Or it may be an indication of damage on the surface of the enamel.
  • Squeaky clean is caused by repeating successive static and dynamic friction along a direction of movement, known in the field as "stick-slip" movement.
  • Stick-slip can be described as surfaces alternating between sticking to each other and sliding over each other, with a corresponding change in the force of friction.
  • the static friction coefficient between two surfaces is larger than the kinetic friction coefficient, which is the "stick” component. If an applied force is large enough to overcome the static friction, then the remaining kinetic friction can cause a sudden jump in the velocity of the movement; this is the "slip" component.
  • Smooth sliding is when a fluid film, by virtue of viscous forces, is formed. This film maintains a gap that ensures the applied load (for example a finger, a cloth, a probe) is fully supported by the lubricant within the space or gap between the parts in motion relative to one another, and solid-solid contact is avoided. So smooth sliding occurs rather than stick-slip.
  • the present invention enables the individual user to make an accurate and useful assessment of the squeaky clean property of surfaces, easily and quickly, when and where required, for example at point of sale, in the home or on the move.
  • the present invention also allows the assessment of the effect of different films or deposits on a surface.
  • the films or deposits may be provided by a product or treatment regime, for example one that is remedial or beneficial.
