degrees of freedom
A degree expressing freedom of movement equivalent to that of human joints. 4th degree of freedom is equivalent to the degree of freedom enabled by the human shoulder (front, back, up, down, rotation) and the elbow (bending).
 digital signal processor (DSP)
A microprocessor ideal for processing voices and images.
 central pattern generator (CPG)/ numerical perturbation (NP) method
Central pattern generator (CPG) - a neural-oscillator system that combines multiple neural oscillators, similar to features found in earthworms and lampreys; a type of neural network used in engineering. Neural oscillator - a part of the central nervous system that is found in vertebrates and is believed to generate a periodic rhythm. Numerical perturbation method (NP) method - a method of analysis used to approximate nonlinear functions that are difficult to analyze. Long used to calculate satellite orbits, in recent years this technique has been applied to fluid dynamics and quantum dynamics. The numerical perturbation method uses a computer to numerically process perturbations. The CPG/NP method is a method used for generating smooth and natural motion of robots, utilizing CPG networks and the NP method. Fujitsu employed the CPG/NP method for the humanoid robots it developed, HOAP-1 and HOAP-2, to enable speed learning of motion.
 natural prosody speech synthesis method
A speech synthesis method developed by Fujitsu Laboratories Ltd. that can synthesize remarkably natural voice in various speech styles, by using the prosody pattern which is extracted from a natural human voice. Prosody refers to the characteristics of speech, such as intonation, rhythm, and volume.
Founded in 1968 as a wholly owned subsidiary of Fujitsu Limited, Fujitsu Laboratories Limited is one of the premier research centers in the world. With a global network of laboratories in Japan, China, the United States and Europe, the organization conducts a wide range of basic and applied research in the areas of Multimedia, Personal Systems, Networks, Peripherals, Advanced Materials and Electronic Devices.
