Abstract: According to some embodiments of the present disclosure, methods of forming a semiconductor device on a semiconductor layer having opposing first and second surfaces are disclosed. An n-type doped region including an n-type dopant may be formed at the first surface of the semiconductor layer. A p-type dopant source layer including a p-type dopant may be formed on the n-type doped region.

After diffusing the p-type dopant, the p-type dopant source layer may be removed.

Abstract: A controller reduces power output of an inverter of an electric drive system while a sensed temperature associated with the inverter, a sensed current output of the inverter, and parameter values of a busbar of the inverter are indicative of a predicted temperature of the busbar being greater than a threshold to maintain busbar temperature lower than the threshold. The current output of the inverter may be outputted over the busbar. The parameter values are obtainable from a thermal model of the busbar. The thermal model may be derived from testing a test version of the inverter under different drive cycles in which for each a set of information is recorded including a sensed temperature of the test inverter, a sensed current output of the test inverter, and a sensed temperature of the busbar of the test inverter.

Abstract: Systems and methods presented herein generally provide for the compensation of asset providers and/or communications network providers for the non-consumption of assets provided with programming. In this regard, when users elect not to consume the assets associated with the programming, the asset provider loses the opportunity to present their assets to such non-consuming users and is thereby injured in relation to the price they have paid for the delivery of their assets. In one arrangement, a reporting module at a customer device is operative to identify when a user skips an asset and report that skip event to the network. This information may then be utilized to adjust the bill of the asset provider and/or to bill the user associated with the skip event.

Abstract: An authentication system is implemented for authenticating the identity of an entity. By registering and verifying user accounts for entities using the authentication system, the authentication system ensures with high confidence that user accounts are associated with verified entities. Authenticating identities between entities may be established and represented in the authentication system by authenticated identity objects. The entities may access the authenticated identity objects by requesting dynamic tokens linked to the authenticated identity object. A requesting entity can provide the dynamic token to another entity who may then provide the dynamic token back to the authentication system. Based on verifying the dynamic token, the authentication system provides an indication of a verification of the entity. In this way, an entity may rely on the verification prior to further interacting with another entity or individual.

In one arrangement, after selecting an asset, the asset is inserted into the content stream and the content stream is disseminated to subsequent network platforms (e.g., local platforms). At this time, the local platforms may insert local assets into the content stream in predetermined local asset insertion spots.

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: Methods, apparatus, and systems to non-invasively determine intra-luminal placement and patency of a vascular access device. Patency and/or placement are estimated indirectly by measuring a physiological parameter which is indicative of proper patency and/or placement of the vascular access device in a patient. The measurement is compared to a reference value or calibration. If the comparison indicates indication of proper patency and/or placement, a signal is generated. The signal can be used in a number of ways. One example is to give a user-perceivable alarm or indication of proper patency and/or placement. Non-limiting examples include activating a light, an audible buzzer, a vibration, readable displayed text or graphics, or some combination of the same. The user can then have an indirect and at least semi-automatic way of estimating proper patency and/or placement of a vascular access device.
