Abstract: After start of an electric drive system, a controller reduces power output of an inverter responsive to sensed temperature of a power switch of the inverter, sensed current of a power electronics module, sensed DC-link voltage, and thermal impedance parameters of a DC-link capacitor being indicative of an estimated temperature of the DC-link capacitor that is greater than a threshold to maintain DC-link capacitor temperature lower than the threshold.

Abstract: Data account management systems and methods are described. A server is in communication with one or more information source systems, at least one user device associated with at least one user and one or more electronic data accounts associated with the user. The server links the electronic data accounts, monitors data among the information source systems and the linked accounts for any changes in activity associated with the user, predicts a behavioral activity of the user via machine learning based on at least one of the monitored data and historical data associated with the user, identifies at least one notification instruction specific to the user based on the predicted behavioral activity, and generates an interactive graphical user interface (GUI) for display on the user device. The interactive GUI presents one or more of the notification instruction and a user profile of the at least one user among the linked accounts.

Abstract: An electric drive system includes a power electronics module (PEM) having a DC-link capacitor and an inverter. A controller reduces power output of the inverter while a sensed temperature of an inverter power switch, a sensed current of the PEM, such as a sensed ripple current of the DC-link capacitor, and parameter values of the DC-link capacitor are indicative of a predicted temperature of the capacitor being greater than a threshold to maintain capacitor temperature lower than the threshold. The parameter values are obtainable from a thermal model of the DC-link capacitor. The thermal model may be derived from testing a test version of the PEM under different drive cycles in which for each drive cycle a set of information is recorded including a sensed temperature of the inverter power switch test version, a current of the PEM test version, and a sensed temperature of the DC-link capacitor test version.

Abstract: A system includes an ion source configured to generate ions having a first polarity, one or more extraction electrodes configured to extract the ions from the ion source as an ion beam having an extraction energy, a mass resolving slit or aperture configured to select a desired isotope from the ion beam such that a desired isotopic ion beam passes through the mass resolving slit or aperture, a target positioned relative to the mass resolving slit or aperture so that the desired isotopic ion beam is incident on the target, and a voltage source coupled to the target and configured to hold the target at a first voltage having the first polarity. The first voltage causes a reduction of the extraction energy as the desired isotopic ion beam approaches the target to minimize sputtering and maximize collection of the ions on the target to reconstitute an ionized material.

Abstract: A media item recommendation can be based on application purchase data. Application purchase data of a population of users can be used to create application preference clusters that represent unique application preference profiles. Media preference data of the same population of users can be used to create media preference clusters that represent unique media preference profiles. A preference relationship between an application preference cluster and a media preference cluster can be identified based on the number of members of the media preference cluster that are also members of the application preference cluster. Upon receiving a recommendation request from a user, the user's application preference profile can be determined based on the user's application purchase data. A media item can then be recommended based on a media preference cluster that has a preference relationship with an application preference cluster that represents the application preference profile of the user.
