  • Patent number: 11972971
    Abstract: A wafer lift pin system is capable of dynamically modulating or adjusting the flow of gas into and out of lift pins of the wafer lift pin system to achieve and maintain a consistent pressure in supply lines that supply the gas to the lift pins. This enables the wafer lift pin system to precisely control the speed, acceleration, and deceleration of the lift pins to achieve consistent and repeatable lift pin rise times and fall times. A controller and various sensors and valves may control the gas pressures in the wafer lift pin system based on various factors, such as historic rise times, historic fall times, and/or the condition of the lift pins. This enables smoother and more controlled automatic operation of the lift pins, which reduces and/or minimizes wafer shifting and wafer instability, which may reduce processing defects and maintain or improve processing yields.

  • Patent number: 11916471
    Abstract: An example electronic device includes a controller to determine a user touch detection by a power adaptor coupled to the electronic device to operate the electronic device in an AC power mode. The power adaptor may comprise a proximity sensor to detect a user touch for detachment of the power adaptor from the electronic device, and a control circuit to operate a configuration pin in a low output mode to signal user touch detection. The controller may initiate central processing unit (CPU) throttling to reduce power consumption by the electronic device. The controller may further stop CPU throttling in response to detecting that the power adaptor has been detached from the electronic device. Further, the controller may switch the electronic device to a DC power mode to operate using DC power supplied by a battery of the electronic device in response to power adaptor detachment.

  • Patent number: 11414783
    Abstract: A method of fabricating one or more colour centres in a crystal is described. The method comprises focusing a laser into a crystal to induce the creation, modification, or diffusion of defects within a focal region of the laser. Fluorescence detection is used to determine when one or more colour centres are formed within the focal region and the laser is terminated when a desired number of colour centres have been formed. The method enables colour centres to be formed in a crystal with a high degree of control in terms of both the number and location of colour centres within the crystal, and a degree of control over other parameters such as colour centre orientation and local environment. In particular, it is possible to form a well-defined pattern of colour centres within a crystal.
