  • Publication number: 20240112904
    Abstract: Disclosed are systems and methods for improving front-side process uniformity by back-side doping. In some implementations, a highly conductive doped layer can be formed on the back side of a semiconductor wafer prior to certain process steps such as plasma-based processes. Presence of such a back-side doped layer reduces variations in, for example, thickness of a deposited and/or etched layer resulting from the plasma-based processes. Such reduction in thickness variations can result from reduced variation in radio-frequency (RF) coupling during the plasma-based processes.

  • Publication number: 20240104149
    Abstract: A computing system is provided, including one or more processors configured to provide a social media platform configured to serve a content feed to a user. The processor is further configured to generate user content interaction information by detecting user interactions with the content feed and provide a recommendation engine that selects content items for display in the content feed based on the generated user content interaction information. The processor is further configured to receive a refresh request to refresh the recommendation engine and refresh the recommendation engine at least in part by masking or resetting the user content interaction information upon receiving the refresh request. After the refresh, the processor is further configured to generate, via the recommendation engine, post-refresh content items based on the masked or reset user content interaction information, and transmit the post-refresh content items to the user device for display in the content feed.

    Abstract: One aspect of the present disclosure includes a delivery tool configured to deliver a neurostimulator into a pterygopalatine fossa of a subject. The neurostimulator can include a body connected to an integral stimulation lead having one or more stimulating electrodes. The delivery tool can comprise a handle, an elongated shaft extending from the handle, a hub portion, and a double barrel sheath. The hub portion can be located between the shaft and a spine member that extends axially away from the hub portion. The hub portion can be sized and dimensioned to releasably mate with the neurostimulator. The double barrel sheath can be connected to the spine member. A central lumen can extend through at least a portion of the shaft and the hub portion. The central lumen can be adapted to receive a lead ejector for selective deployment of the stimulation lead from the double barrel sheath.

  • Publication number: 20220361954
    Abstract: Novel tools and techniques are provided for implementing intelligent assistance (“IA”) or extended intelligence (“EI”) ecosystem to placement procedures for cardiac implantable electronic device (“CIED”). In various embodiments, a computing system might analyze received one or more first layer input data (i.e., room content-based data) and received one or more second layer input data (i.e., patient and/or tool-based data), and might generate one or more recommendations for guiding a medical professional in performing a CIED placement procedure in a heart of the patient, based at least in part on the analysis, the generated one or more recommendations comprising 3D or 4D mapped guides toward, in, and around the heart of the patient. The computing system might then generate one or more XR images, based at least in part on the generated one or more recommendations, and might present the generated one or more XR images using a UX device.

  • Publication number: 20220266034
    Abstract: An implantable medical device performs a method that includes detecting a cardiac event interval that is greater than a P-wave oversensing threshold interval. In response to detecting the cardiac event interval greater than the P-wave oversensing threshold interval, the device determines the amplitude of the sensed cardiac signal and withholds restarting a pacing interval in response to the amplitude satisfying P-wave oversensing criteria. A pacing pulse may be generated in response to the pacing interval expiring without sensing an intrinsic cardiac electrical event that is not detected as a P-wave oversensing event.

  • Patent number: 10863846
    Abstract: A motor driven system for raising and lowering a window covering executes motor ramp trajectory speed control. The motor ramp trajectory limits acceleration of an external motor from the idle (stationary) state to full operating speed, and limits deceleration of the motor from full operating speed back to the idle state. This function reduces stresses on a continuous cord loop drive mechanism. A control system manages solar heating effects in response to sunlight entrance conditions such as system sensor outputs, external weather forecasts, and other data sources. The system automatically opens or close the window covering to increase or decrease admitted sunlight under appropriate conditions. The input interface of the control system includes a visual display and input axis, which are aligned vertically if the window covering mechanism raises and lowers the window covering, and are aligned horizontally if the window covering mechanism laterally opens and closes the window covering.
