Embodiment Construction

[0021] figure 1 An electronic blanket 1 suitable for use as a bed blanket is shown. The electronic blanket 1 is here formed of a textile web 2 with a sensor array 3 and a sensor target 4 adapted to affect the sensor array.

[0022] The sensor array 3 here comprises four proximity sensors 31 , 32 , 33 , 34 , each sensor being an inductive proximity sensor capable of generating an electromagnetic field. Each proximity sensor 31 , 32 , 33 , 34 here has a detection range of 150 mm, and within this range the proximity sensor 31 , 32 , 33 , 34 is able to detect Changes in the electromagnetic field. The sensor array 3 may be integrated in the paddle or attached to the paddle. The sensor target 4 is here a metal wiring.

[0023] The proximity sensors 31 , 32 , 33 , 34 and sensor target 4 are positioned in such a way that if any of the proximity sensors detects a sensor target, this indicates that the electronic blanket has assumed a given state. The given state is here the state ...

Abstract

An electronic blanket (1) comprising a sheet (2) of a foldable material, a sensor array (3), including one or several sensors (31,32,33,34), and a sensor target (4) adapted to affect said sensor array, wherein said sensor array is adapted to detect presence of said sensor target (4), said sensor array (3) and said sensor target (4) being attached to said sheet (1). The blanket also comprises circuitry (5) arranged to generate a state variable in response to detections by said sensor array (3), wherein said sensor array (3) and said sensor target (4) are arranged so that said state variable indicates when said electronic blanket has assumed a given state. As the sensor array and the sensor targets are both attached to the sheet, they provide information related to the positioning of the blanket in relation to itself.

Description

technical field [0001] The present invention relates to an electronic blanket to be used, for example, as a bed sheet, bed cover or curtain. Background technique [0002] It is well known in the art to employ electronic components in blankets to provide additional functionality. [0003] US 7,144,830 discloses a textile comprising electronic functionality and which can be used eg in a blanket. By providing a first type of functional yarn containing sensors and / or light sources and a second type of functional yarn containing a processor in the same fabric, it is possible to weave "smart" fabrics that can sense data and process sensory information. The measured data is generated for addressing of the illuminating light source and illuminating the addressed light source. [0004] As proposed in US 7,144,830, prior art arrangements may include sensors of temperature, force, pressure, sound, magnetic field or some other condition and thereby detect conditions in the environment...
