Abstract: A method and system for providing wireless power transfer through a metal object is provided. In one aspect, an apparatus for wirelessly receiving power via a magnetic field is provided. The apparatus includes a metal cover including an inner portion and an outer portion. The outer portion is configured to form a loop around the inner portion of the metal cover. The outer portion is configured to inductively couple power via the magnetic field. The apparatus includes a receive circuit electrically coupled to the outer portion and configured to receive a current from the outer portion generated in response to the magnetic field. The receive circuit is configured to charge or power a load based on the current.

Abstract: There is herein described a structure for converting light from LED arrays from shorter wavelength, for example blue, into longer wavelength light, for example red and green, so as to form displays containing red, green and blue sub-pixels. More particularly, the present invention relates to a structure and process in which light from LED arrays of the same wavelength is converted into alternate colours by means of a colour conversion structure.

Abstract: A system includes an inductive backplane, at least one communications interface, and a control unit. The inductive backplane is configured to secure and inductively power a plurality of detachable medical device modules. The control unit controls, via the at least one communications interface, at least one attribute of each medical device module when the medical device module is secured to the inductive backplane. Related apparatus, systems, techniques and articles are also described.

Abstract: A system includes an inductive backplane, at least one communications interface, a control unit and an intelligent power module. The inductive backplane is configured to secure and inductively power a plurality of detachable medical device modules. The control unit controls, via the at least one communications interface, at least one attribute of each medical device module when the medical device module is secured to the inductive backplane. The intelligent power module monitors at least one parameter of the detachable medical device modules. Related apparatus, systems, techniques and articles are also described.

Abstract: There is disclosed an electroluminescent device (200; 300; 400; 500) in which a phosphor (6) is deposited in gaps (3) between electrodes (2a, 2b). The deposition of phosphor on top of the electrodes is minimised as phosphor on top of the centre of an electrode will not experience a significant electrical field and thus will not usefully emit light. Some embodiments improve the efficiency with which phosphor is utilised during manufacture. In some embodiments (400; 500) the electrodes and phosphor may be on opposite sides of a substrate (1). In some embodiments (100), the phosphor has a sufficiently high dielectric strength that a dielectric layer between the phosphor and the electrodes is not required.
