    • A Totally Modular Arm Prosthesis 

      Kyberd, Peter J.; Gow, David; Sperling, Lena; Boman, Andreas (1999)
      While some groups and centres have attempted to promote greater levels of sophistication in exo-prosthetics it is only in the past couple of year s that the ideas of computer control to be applied in prostheses has receiived ...
    • CANCELLATION OF FORCE INDUCED ARTIFACTS IN SURFACE EMG USING FSR MEASUREMENTS 

      Fougner, Anders; Sæther, Marthe; Stavdahl, Øyvind; Kyberd, Peter J.; Blum, Jeremy (2008)
      As multifunction prostheses become increasingly common, there is a need for improved control signal quality in order to control all the functions. Most signals commonly used for prosthesis control are sensitive to sweaat, ...
    • Experience With Hierarchically Controlled Hand Prosthesis 

      Kyberd, Peter J. (1999)
      The principles of hierarchical control ofhand prostheses have been described in previous MEC meetings. Simply put: It is possible to achieve easy use of a multi-axial artificial hand if the detailed control of the hand'ss ...
    • Multimodal Input Device With SEMG And Contact Force Sensors 

      Stavdahl, Øyvind; Kyberd, Peter J.; Magne, Tordis; Ottermo, Maria V.; Mugaas, Terje (2011)
      In myoelectric prostheses, movement artifacts are known to impair control performance. This study relates to a novel sensor which measures surface electromyograms (SEMG) as well as contact force at the electrode-skin intterface. ...
    • The Use of Fuzzy Logic In the Processing Of Myoelectric Signals 

      Taffler, Sean; Kyberd, Peter J. (1999)
      This paper describes the use of Fuzzy logic for the processing of EMG signals. This can increase the recognition rate and significantly reduce the number of computations required to generate an output. The initial placemment ...
    • The use of the Hilbert transforra in EMG Analysis 

      Taffler, Sean; Kyberd, Peter J. (1999)
      The Fourier transform has traditionally been used for the detailed analysis of EMG signals. This has yielded many useful results, none more so than the descriptions of the energy produced at differing frequencies. This hhas ...
    • Using multiple outcome measures to determine skill level in myoelectric prosthesis use 

      Bouwsema, Hanneke; Kyberd, Peter J.; Hill, Wendy; van der Sluis, Corry K.; Bongers, Raoul M. (2011)
      Most studies on prosthesis usage focus merely on one type of outcome measures, using questionnaires, functional tests, or kinematics. However, a combination of several outcome measures should provide a better picture on ...
