  • Publication number: 20170095038
    Abstract: A strain relief element for a footwear article is provided. The strain relief element is engageable with a portion of a footwear article for engagement with a portion of the foot of a subject, wherein the strain relief element is formed from an elastically deformable material, the strain relief element is sized and provided with a geometry, such that upon engagement with the engagement portion of a foot of a subject, the strain relief element elastically deforms and the internal surface of the strain relief element which engages with the foot of a user substantially conforms to the engagement portion of the surface of the foot of a subject. Footwear including such a strain relief element are also provided.

  • Publication number: 20160089078
    Abstract: Disclosed is a device for sleep monitoring, which includes a detecting module, a processing module electrically connected with the detecting module and an output module electrically connected with the processing module. The detecting module is used for collecting physiological feature signals which represent sleep state of user, the physiological feature signals include one or more than one of heart rate feature signals which represent the heart rate of user and respiration feature signals which represent the respiration of user; the processing module is used for processing the physiological feature signals from the detecting module so as to obtain evaluation results of sleep of user; and the output module is used for outputting the evaluation results of sleep from the processing module. By collecting the physiological feature signals which represent the heart rate and/or respiration of user during sleep, the sleep quality of user can be evaluated accurately.

  • Publication number: 20150230547
    Abstract: The footwear article comprises a generally elongate sole having a first portion for interaction with a ground surface during ambulation, a second portion for interaction with the ground surface during ambulation, and a third portion between the upper surface and the lower surface. The first portion includes a first material with a first material property, the second portion includes a second material with a material property, and the third portion includes a material with a third material property. The first and portions extend to the upper surface of the sole. The first material property provides dampening of impact load imparted to the foot of the person upon contact of the footwear article with the ground surface. The third material property is a visco-elastic property for providing controlled deformation upon contact of the footwear article with the ground surface and returns to an initial state upon removal of the impact.
