Abstract: A contact sensor and system for incorporation within clothing and other wearable items to monitor activity at a body surface. The sensor includes a contact membrane having a body surface contacting area and one or more base layers of knitted fabric. The base layer(s) is thicker over an area congruent with the body surface contacting area of the contact membrane. As a result, the contact membrane is urged into the forming of a raised outer surface for projection against a body surface.

Abstract: Embodiments of the present invention provide a method of reducing power consumption in a wireless network device, comprising determining a duration prior to a beacon being received by the device; comparing the duration against a predetermined value; and adjusting a duration of a sleep period in response to the comparison.

Abstract: The present invention relates to deformable supports that provide a compressive force on a human or animal limb or body and can self-determine that force and monitor it. The invention further relates to garments comprising those supports and an associated system for self-determination, monitoring and communicating the compressive force.

Abstract: In a control method for a power converter, an output voltage is generated according to a control law controlling a switched power stage. During ramp up of the power converter, at least one parameter of the power stage is identified, and the control law is adapted to the identified at least one parameter of the power stage for operating the power converter.

Abstract: A control method is provided for a power converter configured to generate an output voltage according to a control law controlling a power stage. The method comprises a dual stage identification process for identifying parameters of the power stage. The method includes, in a first stage, identifying at least one parameter of the power stage during ramp up of the power converter and adapting the control law to the identified at least one parameter of said power stage for operating the power converter. The method further includes, in a second stage, determining a response of the power stage; identifying at least one other parameter of the power stage by characterizing the response; and further adapting the control law according to a characteristic of the response.
