Abstract: A battery system includes a battery subpack having first and second battery cells, a cell monitoring circuit, a RF transmitter, an RF receiver, a subpack microprocessor, and a first transceiver. The circuit measures a voltage of a first battery cell. The system includes a master controller having a second transceiver. The RF transmitter sends a voltage value corresponding to the voltage of the first battery cell to the RF receiver. The subpack microprocessor determines the first battery cell has an overvoltage condition based on the voltage value and sends an overvoltage message to the master controller via the first and second transceivers. The subpack microprocessor induces first and second subpack contactors to each have an open operational state when the master controller sends an open command to the subpack microprocessor.

Abstract: A method optimizes machine learning systems. A computing device accesses a committee of classifiers that have been trained using an initial labeled instance of data from an annotator. The initial labeled instance of data includes annotator-ranked attributes of the data, initial values of the attributes, and an initial prediction label that describes an initial predicted state based on the values. The computing system compares the attributes ranking from the annotator to attributes rankings that are generated by and used by each of the machine learning systems when evaluating one or more instances of unlabeled data that include the attributes, and weights the machine learning systems according to how closely each of the attributes rankings generated by and used by each of the machine learning systems match the attributes ranking from the annotator. The machine learning systems are then optimized based on this matching.

Abstract: Embodiments provide devices, systems and methods for preventing deep vein (DV) thrombosis (DVT). One embodiment provides a DVT prevention device including a cuff that fits over a patient's knee, an applanator coupled to an inside cuff surface, an expandable member (EM) coupled to the applanator, a pressure source fluidically coupled to the EM and a controller for controlling EM inflation. When the EM is inflated, it applies a force to the applanator which is transmitted to the knee back surface causing a popliteal vein (PV) under the cuff to be compressed so as to increase backpressure behind the compressed PV and subsequently increase the velocity of blood flow in the leg DVs when the EM is deflated. The EM can be inflated in a cycle including pulsed inflation, inflation hold and relaxation. The cycles can be repeated and adjusted to achieve a desired increase of blood flow/velocity in leg DVs.

Abstract: An online concierge system receives information describing items in orders placed by a customer and a sequence of events associated with each order and identifies an impulse item included in the orders based on a set of rules, attributes of each item, and/or the sequence of events. The system applies a model to predict a measure of similarity between the impulse item and each of multiple candidate items and identifies larger-size variants of the impulse item based on this prediction and attributes of the impulse item and each candidate item. The system applies another model to predict a likelihood the customer will order each variant, computes a recommendation score for each variant based on this prediction, and determines whether to recommend each variant based on the score. Based on the determination, the system generates and sends a recommendation for a variant to a client device associated with the customer.
