An invertebrate capturing device comprising a main body having an interior passage for connection with a vacuum source. The method includes determining, by a processor, the alignment of the detector with respect to a collimated radiation beam. The generation of the invocation sequence by the synthesizer removes the need for complex hand encoding of form structures, and provides a means by which the functions may be generated as part of a server, client or middleware application. The frequency of the transmitted signal at the moment when the comparison indicates that the sensor is being driven at its resonant frequency is the resonant frequency of the sensor. The organic light emitting display device includes a substrate, a first electrode formed on the substrate, an inorganic pixel defining layer formed on the first electrode and having an opening exposing at least a portion of the first electrode, an organic layer disposed on the first electrode and having at least an organic emission layer, and a second electrode formed on the organic layer.
