Abstract: Described herein are systems and methods for operating DC-DC regulators such as LED drivers. Various embodiments herein allow a DC-DC regulator to switch between buck mode and buck-boost mode without suffering effects otherwise resulting from transient currents when switching between modes. In certain embodiments, this is accomplished by operating the DC-DC regulator in a buck-boost mode to charge a boost capacitor with a substantially constant inductor current. The inductor current is also used to control a set of switches to operate the DC-DC regulator in a buck mode to drive a load by using the capacitor as a power source.

Abstract: Methods and systems for providing message playback using a shared electronic device is described herein. In response to receiving a request to output messages, a speech-processing system may determine a group account associated with a requesting device, and may determine messages stored by a message data store for the group account. Speaker identification processing may also be performed to determine a speaker of the request. A user account associated with the speaker, and messages stored for the user account, may be determined. A summary response indicating the user account's messages and the group account's message may then be generated such that the user account messages are identified prior to the group account's messages. The messages may then be analyzed to determine an appropriate voice user interface for the requester such that the playback of the messages using a shared electronic device is more natural and conversational.

Abstract: Forming a hardmask layer for reactive ion etching includes depositing a hardmask above an underlayer. The hardmask includes a layer of magnesium oxide having a thickness of up to 10 nm. A resist layer is deposited above the hardmask and developed to form a pattern that exposes portions of the hardmask. The pattern is transferred from the resist layer to the hardmask by rinsing exposed portions of the hardmask with a deionized water solution.

Abstract: A system receives a predictive model and receives one or more runtime constraints. The system generates a directed acyclic graph (DAG) of the predictive model indicating dependencies.

Abstract: A firmware protection module implements a hybrid firmware protection scheme on a computing device. The firmware protection module intercepts a message from a processor to a memory of the computing device. The message includes a command and an address in the memory corresponding to a firmware module stored in the module. The firmware protection module determines whether the command in the message is prohibited and whether the address in the message is protected. Responsive to a determination that the command is prohibited and the address is protected, the firmware protection module prevents at least a portion of the message from reaching the memory.

Abstract: Systems and methods for sender profile and/or recipient profile disambiguation and/or confirmation are disclosed. In instances where a sender profile is not indicated by a user sending a communication from a communal device, heuristic data may be utilized to infer the sender profile. Similar heuristic data may also be used when selection of the sender profile is associated with a low confidence level. Heuristic data may also be used to infer the recipient profile when the user does not indicate the recipient profile or when selection of the recipient profile is associated with a low confidence. Various confirmations may result from the sender and recipient profile disambiguation.

Abstract: A video display hub is mounted in a common household area such as a kitchen or family room. The display hub is configured to display various types of information for users in the area, such as weather, traffic updates, schedules, notes, messages, lists, news, etc. When the user is at a distance from the display hub, information is presented at a relatively low density, with a low level of granularity and detail in conjunction with large fonts, graphics, and icons. When the user is close to the display hub, information is presented at a relatively high density, with a high level of granularity and detail in conjunction with small fonts, graphics, and icons.
