Abstract: Aspects of the disclosure include a threat detecting apparatus. The threat detecting apparatus can include an interface circuit, an opcode detector, and a pattern analyzer. The interface circuit is configured to receive a data stream. The opcode detector can be configured to identify an opcode sequence embedded in the data stream based on a first model graph that includes a plurality of interconnected token nodes. Each token node is representative of an occurrence or a non-occurrence of a token. The pattern analyzer may be configured to identify an opcode signature embedded in the identified opcode sequence based on a second model graph, and to output a signal indicative of the successful identification of the opcode signature. The second model graph can include a plurality of interconnected opcode nodes, and each opcode node can be representative of an occurrence or a non-occurrence of a predetermined combination of one or more opcodes.

Abstract: An iontophoretic delivery device utilizing a polymeric gel matrix to ameliorate pH deviation within the device wherein the pH of the polymeric gel matrix is buffered at select pH ranges in order to reduce skin irritation. The polymeric gel matrix is housed within the iontophoretic delivery device as a buffering agent wherein the matrix provides a suitable physiological pH level above 4.0 and particularly the pH level deviates between approximately 4.1 to approximately 4.9, and preferably at the pH 4.5 for an effective operation of the iontophoretic delivery of a medicament to treat affected areas of a living subject's body.
