    A prosthesis is conventionally controlled and monitored by recording and converting the electrical signals from the muscles (electromyography) into machine-understandable signals. However, the activity of the muscle can be registered not only electrically, but also magnetically, as every electrical activity within the muscle also generates a magnetic field. This magnetomyography originates from the same ionic currents and presents comparable temporal and spectral profiles, but poses two potential advantages over electromyography: A) the intrinsic contactless nature of the measurement and b) a theoretical superiority when it comes towards the decomposition of muscle signals. MMG can be recorded contactless as the magnetic permeability of human tissue is comparable to that of empty space and thereby magnetic field is less distorted. This suggests a possible superiority of MMG for the study of muscle signal and theoretically leads (in silico) to a twofold discrimination of motor neurons of the spinal cord, when compared to electromyography. Despite these advantages, current challenges are the need for magnetic shielding and sensor size and sensitivity-which can be partly surpassed using nitrogen-vacancy diamond magnetometers. Given the circumstance that little is known for magnetomyography and prosthesis control, we performed several experiments using commercially available optically pumped magnetometer to provide a reference about current technological possibilities (e.g., sensor sensitivity); furthermore, we present a new fully-integrated nitrogen vacancy-based sensor system, which may augment and/or replace traditional biosignal interfaces to peripheral devices such exoprostheses or exoskeletons.

    Intelligent Pointer Unit to Speed Up the Shelf Replenishment Process in Retail Stores

    Shelf replenishment is a repetitive, manually executed, and time-consuming task in retail. This paper addresses this issue with an intelligent pointer unit that helps staff reduce the orientation time for small and similar products in the shelf replenishment process. The user wears a ring scanner to scan an article or its box, whereon the pointer unit illuminates the target shelf position received from a digital store model. A comprehensive evaluation extracts the performance of the pointer unit within two user groups. The results show a reduction of the orientation time of 88.5% for beginners, respectively 75% for experienced staff members. Furthermore, accounting for the times needed for handling and alignment, a reduction of the overall search time of 71.5% for beginners, respectively 22.5% for experienced staff members, has been achieved.

    Quanten-Ghost-Imaging mit asynchroner Detektion
    Ein fortschrittlicher Aufbau für Quanten-Ghost-Imaging ermöglicht rauscharme 3-D-Bildgebung von entfernten Objekten. Eine wesentliche technische Neuerung liegt in der asynchronen Detektion durch unabhängige SPAD-Detektoren, wodurch sich der Aufbau entscheidend vereinfachen lässt und sich nun für beliebige Entfernungen eignet. Wie jüngste experimentelle Ergebnisse verdeutlichen, besitzt dieser Aufbau das Potenzial, klassische Systeme in vielen Aspekten zu übertreffen.

    Ready or Not, AI Comes - an Interview Study of Organizational AI Readiness Factors

    Artificial intelligence (AI) offers organizations much potential. Considering the manifold application areas, AI's inherent complexity, and new organizational necessities, companies encounter pitfalls when adopting AI. An informed decision regarding an organization's readiness increases the probability of successful AI adoption and is important to successfully leverage AI's business value. Thus, companies need to assess whether their assets, capabilities, and commitment are ready for the individual AI adoption purpose. Research on AI readiness and AI adoption is still in its infancy. Consequently, researchers and practitioners lack guidance on the adoption of AI. The paper presents five categories of AI readiness factors and their illustrative actionable indicators. The AI readiness factors are deduced from an in-depth interview study with 25 AI experts and triangulated with both scientific and practitioner literature. Thus, the paper provides a sound set of organizational AI readiness factors, derives corresponding indicators for AI readiness assessments, and discusses the general implications for AI adoption. This is a first step toward conceptualizing relevant organizational AI readiness factors and guiding purposeful decisions in the entire AI adoption process for both research and practice.
