A method for controlling the output power of power sourcing equipment powering a device through an ethernet cable, comprising: performing a power negotiation between the power sourcing equipment and the powered device, the negotiation comprising establishing a relation between an output voltage of the power sourcing equipment and a loop current from the powered device to the power sourcing equipment by measuring the loop current in a current-sensing device; obtaining indications of whether the powered device needs increased power and whether the power sourcing equipment is able to deliver increased power; if the powered device needs increased power and the power sourcing equipment is of a power sourcing equipment type able to deliver increased power, physically manipulating the current-sensing device such that it senses a manipulated lower loop current; and providing a manipulated higher output power from the power sourcing equipment to the powered device.

In a method of providing a packaging laminate with an identification code the packaging laminate is subjected to a magnetic field, thus magnetising a matrix of magnetic domains in the packaging laminate. Each magnetic domain is made up of a number of the magnetisable particles. A method of identifying a package is also disclosed. The package has walls of a packaging laminate comprising magnetisable particles. The method comprises the steps of subjecting the packaging laminate to a magnetising magnetic field, thus magnetising a matrix of magnetic domains in the packaging laminate, and detecting an emitted magnetic field emitted by the magnetic domains in the matrix. A package having an identification code is also described.

A system and a method for production of a packaging laminate that comprises a layer containing magnetizable particles. The method involves marking faults, such as single spot defects and splices, on the packaging laminate by the application of a magnetic field to make a magnetic mark on the packaging laminate. A packaging device is arranged to sense the presence of the magnetic mark related to a package made from the packaging laminate.
