  • Publication number: 20230020387
    Abstract: A method for forming a coating on a component of a substrate processing system includes arranging the component in a processing chamber and applying a ceramic material to form the coating on one or more surfaces of the component. The ceramic material is comprised of a mixture including a rare earth oxide and having a grain size of less than 150 nm and is applied while a temperature within the processing chamber is less than 400° C. The coating has a thickness of less than 30 ?m. A heat treatment process is performed on the coated component in a heat treatment chamber. The heat treatment process includes increasing a temperature of the heat treatment chamber from a first temperature to a second temperature that does not exceed a melting temperature of the mixture over a first period and maintaining the second temperature for a second period.

  • Publication number: 20230014160
    Abstract: A motorized window treatment for controlling the amount of daylight entering a space through a window includes a covering material, a drive shaft, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions to minimize motor usage and conserve battery life. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors, or in response to an infrared or radio-frequency remote control.

  • Patent number: 11556665
    Abstract: Disclosed herein is a data storage device comprising a data path and an access controller. The data path comprises a data port configured to transmit data between a host computer and the data storage device. The data storage device is configured to register with the host computer as a block data storage device. A non-volatile storage medium stores encrypted user content data and a cryptography engine is connected between the data port and the storage medium and uses a cryptographic key to decrypt the encrypted user content data. The access controller generates a challenge for an authorized device; sends the challenge to the authorized device; receives a response to the challenge from the authorized device over the communication channel; calculates the cryptographic key based on the response; and provides the cryptographic key to the cryptography engine to decrypt the encrypted user content data stored on the storage medium.

  • Patent number: 11556312
    Abstract: A co-processor for performing a matrix multiplication of an input matrix with a data matrix in one step may be provided. The co-processor receives input signals for the input matrix as optical signals. A plurality of photonic memory elements is arranged at crossing points of an optical waveguide crossbar array. The plurality of memory elements is configured to store values of the data matrix. Input signals are connected to input lines of the optical waveguide crossbar array. Output lines of the optical waveguide crossbar array represent a dot-product between a respective column of the optical waveguide crossbar array and the received input signals, and values of elements of the input matrix to be multiplied with the data matrix correspond to light intensities received at input lines of the respective photonic memory elements. Additionally, different wavelengths are used for each column of the input matrix optical signals.

  • Patent number: 11554017
    Abstract: Dislodgment of a constricting cord from an annulus can be prevented by delivering the distal loop portion of the constricting cord to the annulus using a percutaneous delivery tool, and launching anchors into the annulus so as to affix the distal loop portion of the constricting cord to the annulus. The percutaneous delivery tool is withdrawn in a proximal direction after the anchors have been launched. A pushing member is pressed in a distal direction so that the pushing member holds a portion of the constricting cord against the annulus with enough pressure to prevent dislodgment of any of the anchors during the withdrawal of the percutaneous delivery tool.

  • Patent number: 11558252
    Abstract: The present technology provides a system, method and computer-readable medium for configuration pattern recognition and inference, directed to a device with an existing configuration, through an extensible policy framework. The policy framework uses a mixture of python template logic and CLI micro-templates as a mask to infer the intent behind an existing device configuration in a bottom-up learning inference process. Unique values for device/network identifiers and addresses as well as other resources are extracted and accounted for. The consistency of devices within the fabric is checked based on the specific policies built into the extensible framework definition. Any inconsistencies found are flagged for user correction or automatically remedied by a network controller. This dynamic configuration pattern recognition ability allows a fabric to grow without being destroyed and re-created, thus new devices with existing configurations may be added and automatically configured to grow a Brownfield fabric.
