Abstract: A system for measuring the thermal diffusivity of a material includes a housing having an upper portion and a lower portion, a plate holding the material in a fixed position between the upper portion and lower portion of the housing, and a source at the lower portion of the housing projecting heat onto the material along a first axis that is perpendicular to the plate. A sensor at the lower portion of the housing is movable in relation to the plate and senses the heat radiating through the material along a second axis that is perpendicular to the plate and offset from the first axis. A controller receives data from the sensor and calculates the thermal diffusivity of the material.

Abstract: A device for the photothermic investigation of a sample, with an excitation source for generating an electromagnetic excitation beam directed onto an excitation side of the sample, a detector for detecting thermal radiation emitted by a detection side of the sample, and a temperature-controllable sample chamber with a sample holder accommodated therein for the arrangement and temperature control of the sample. According to the invention, provision is made such that an adjustable detection lens system is provided between the sample holder and the detector, the detection lens system being adjustable in order to adjust a desired field of vision of the detector on the sample surface.

Abstract: A method is disclosed for licensing software components and providing access authorization to software components and/or instantiations of software objects through sublicenses and/or value points, wherein a sublicense and/or value points are associated with each software module and/or the instantiation of a module. Access authorization is based on a comparison between acquired sublicenses/value points and the sublicenses/value points required for an machine task. Sublicenses/value points can be exchanged/traded between different machines and/or users.

Abstract: The invention relates to a method for providing licenses and access authorizations of software components or for instantiation of software objects by the acquisition of value points (WP), wherein every software module or instantiation of a module is associated with a defined number of value points (WP). Licensing is based on a comparison of the acquired value points (WP) (value point credit) with the value points (WP) (value point debit) required for the application.

Abstract: The invention relates to a method for granting licenses and authorising access to software components or instantiations of software objects through the purchase of value points (WP, WP1-WPn), whereby a specific number of value points is allocated to each software module or to each instantiation of a module. Granting licenses is based on a comparison between the acquired value points (WP, WP1-WPn) (credit) and the value points required for an application (WP, WP1-WPn) (debit). The comparison is carried out by a license manager which is advantageously implemented as a mobile agent in distributed environments.

Abstract: A method for determining authorization to use software components of a computer system or a controller using a unique hardware identification code is disclosed. An identification number is generated by an encoding algorithm from a hardware identification code and license information, optionally including additional information. Comparison of encoded and decoded identification numbers will permit or restrict access to the software components.
