Abstract: There are provided methods, systems, and non-transitory storage mediums for performing a meta-prediction of time series by using a set of forecasting models each associated with a forecasting theme. Time series data is received, and a set of forecast signals is generated. At least one signal and feature processing model generates a set of features. A meta-learner having been trained on historical time series data generates, based on the time series data and the set of features, a set of weights for the set of forecasting models. A meta-prediction is generated by using the set of features and forecast signals. Implementations may use combinations of endogenous and exogenous data, latent space transformations and generate interpretations and explanations for the meta-prediction.

Abstract: A locking arrangement for a patient lift configured to selectively lock the vertical movement of a patient support mounting device connected to a lifting device of the patient lift via a load bearing member. The locking arrangement including a shape memory alloy element and a locking device. The shape memory alloy element is connected to the locking device and arranged to selectively actuate the locking device to control a locking force on an engagement member mechanically connected to a motor and the load bearing member of the patient lift. The present invention further relates to a patient lift including the locking arrangement.

Abstract: An exoskeletal (or endoskeletal) ankle connector for use in fixedly securing a prosthetic foot to a prosthetic leg. The foot has an elongated cantilever spring type keel. The keel defines an elongated forefoot part, an ankle part and a heel part merging the ankle part with the forefoot part. The keel ankle part is provided with a cavity. The leg has a bottom end with an integral bolt with the bolt having a free projecting threaded stem.
