Abstract: A method for determining a predicted state of health of an electrical energy storage unit in a machine includes providing a data-based or hybrid state of health model, the data-based state of health model is trained, depending on operating variables of the electrical energy storage unit and/or operating features derived from the operating variables, to indicate a state of health and to indicate a model uncertainty of the indicated state of health, ascertaining a state of health characteristic and the associated model uncertainty of the energy storage unit based on the operating variables using the state of health model, and generating at least one random constructed state of health characteristic candidate that corresponds to constructed state of health characteristics within characteristic of confidence intervals, the characteristic of confidence intervals defined by the model uncertainties of the states of health of the ascertained state of health characteristic.

Abstract: A method for operating a system for ascertaining a state of charge of a battery of a motor vehicle includes providing operating variables of the battery, providing a calculated state of charge in the motor vehicle using a state-of-charge model that indicates a calculated state of charge depending on at least one battery model parameter of the state-of-charge model for the battery, and ascertaining a reference state of charge using a reference state-of-charge model depending on the operating variables. The reference state-of-charge model is trained to indicate the reference state of charge depending on the operating variables and/or a predefined aging state. The method further includes performing a correction of the at least one battery model parameter depending on a difference between the reference state of charge and the calculated state of charge in order to adapt the calculated state of charge to the reference state of charge.

Abstract: A bone segment positioning device including a base shaft, wherein the base shaft includes a base mating structure and an anchoring thread for securing the base shaft to a distal portion of a broken bone. Additionally, a collar shaft is provided, wherein the collar shaft includes a stabilizer base and a collar mating structure configured for associating with the base mating structure to secure the base shaft to the collar shaft. Moreover, a stabilizing device is provided, wherein the stabilizing device includes a collar configured for associating with the stabilizing base to secure the collar shaft with a proximal portion of the broken bone.

Abstract: A system and method for repairing fractured long bones. A guide wire is inserted through an opening drilled in a proximal bone segment and pushed through the intramedullary cavity of the proximal bone segment, across the fracture site and into the intramedullary cavity of a distal bone segment. A dilator is inserted over the guide wire and pushed through the intramedullary cavity into the distal bone segment to a stop at the distal end of the guide wire. A flexible tube having a radially expandable distal portion is then pushed over the guide wire into the distal bone segment and against the dilator. A compression nut is threaded over the proximal end of the guide wire to engage the proximal bone segment and compress the flexible tube. Compression of the flexible tube deploys the radially expandable distal portion to anchor the device in the distal bone segment.
