    Abstract: A distraction osteogenesis fixture to be anchored in a bone, including a lower anchor, a translational screw, and an upper anchor. At least a portion of the lower anchor is externally threaded. At least a portion of the lower anchor includes an anti-rotational feature. The lower anchor includes an internal passage. At least a portion of the internal passage is threaded. At least a portion of the translational screw is externally threaded such that the translational screw is receivable by the threaded internal passage of the lower anchor. The upper anchor includes an internal passage for receiving a portion of the lower anchor and has an anti-rotational feature for engaging the anti-rotational feature of the lower anchor. The internal passage of the upper anchor includes a surface for engaging the translational screw. At least a portion of the upper anchor is externally threaded.

    Abstract: A power and safety control hub, integrating fault tolerant power disconnect control, software monitoring of disconnect and multi-voltage power distribution and disconnect with non-hazardous power control, EMI filtering and multi-circuit current protection in a single unit, coordinating shutdown of connected mechanical drives, commanding them to come to a controlled stop before safety power is disconnected. The hub may also integrates segmented hazardous power control and automatically discharge energy sources within connected mechanical drives at the time of safety power disconnect of hazardous power. The hub may also include internal self-protection that automatically forces a control safety power disconnect (after warning the host) if the unit should approach its maximum operating temperature, or if a cooling fan stops.

    Abstract: A method of determining at least the concentration of a component from the intensity of electromagnetic waves with at least two selected wavelengths which are reflected by human tissue or transmitted through human tissue comprises firstly the step of converting the intensities of the received electromagnetic signals into at least one first and one second time-dependent electric signal. Then a time-discrete transformation of the first and of the second electric signal into the frequency domain is performed to determine first and second spectral values of the first and of the second signal. Complex combinatorial values are formed from said first and second spectral values and physiologically relevant combinatorial values are selected by evaluating the complex combinatorial values according to given criteria for the physiological relevance thereof. Finally, the concentration of the component is calculated by using the selected combinatorial values or by using the frequencywise-associated spectral values.
