Abstract: A disinfection device includes a radiation lamp (112) having an aperture for delivering radiation. A flexible shroud (132) surrounds a perimeter of the aperture. The shroud includes a surface configured to deform and create a seal around the aperture when in contact with a target surface. A sensing circuit (120, 156) is configured to sense a state of the seal and enable the radiation lamp when the seal is complete.

Abstract: An accessory enabled device includes a first device (102) including a selectively activated feature (105). An interrogation source (108) is configured to interrogate an accessory device (106), such that, responsive to an interrogation, feedback from the accessory device is measured to determine compatibility between the first device and the accessory device. The selectively activated feature is enabled to perform a task only when compatibility exists between the first device and the accessory device.

Abstract: A disinfection device includes a reflective surface (107) configured to direct light at a plurality of angles toward a target surface (108). The reflective surface forms a partial enclosure and has end portions (110). A light source (104) is disposed within the partial enclosure, wherein at least a portion of the light source is positioned within the partial enclosure such that light from the light source is reflected off the end portions to provide an angle of incidence on the target surface to treat an under-shadow region of an object or an uneven target surface.

Abstract: The present invention relates to an extended wear biomedical electrode assembly, comprising at least two conductive gel pads spaced apart from each other, electrodes in contact with the gel pads, a support construction disposed substantially laterally with respect to the gel pads, surrounding the gel pads, filling space between neighboring gel pads, and overlapping an lower, outer perimeter of each of the gel pads. A smooth, even skin-contacting surface and a mechanical decoupling of the connector from the skin improve user comfort.
