Abstract: A camera may capture reflected light from the surface of the wafer during a semiconductor process that adds or removes material from the wafer, such as an etch process. To accurately determine an endpoint for the process, a camera sampling rate and light source intensity may be optimized in the process recipe. Optimizing the light source intensity may include characterizing light intensities that will be reflected from the waiver using an image of the wafer. Pixel intensities may be used to adjust the light source intensity to compensate for more complex wafer patterns. Optimizing the camera sampling rates may include nondestructively rotating a view of the wafer and converting the sampled intensities to the frequency domain. The camera sampling rate may be increased or decreased to remove spatial noise from the image without oversampling unnecessarily. These optimized parameters may then generate a clean, repeatable trace for endpoint determination.

Abstract: The present disclosure provides an inspection system and a method of stray field mitigation. The system includes an array of electron beam columns, a first permanent magnet array, and a plurality of shielding plates. The array of electron beam columns each includes an electron source configured to emit electrons toward a stage. The first permanent magnet array is configured to condense the electrons from each electron source into an array of electron beams. The first permanent magnet array is arranged at a first end of the array of electron beam columns. The plurality of shielding plates extend across the array electron beam columns downstream of the first permanent magnet array in a direction of electron emission. The array of electron beams pass through a plurality of apertures in each of the plurality of shielding plates, which reduces stray magnetic field in a radial direction of the array of electron beams.

Abstract: A computer includes a processor and a memory storing instructions executable by the processor to input steering torque data and steering wheel angle data to a machine learning program trained to output a status of a hand of an occupant relative to a steering wheel, the status being one of (1) the hand is on the steering wheel, (2) the hand is off the steering wheel and no weight is applied to the steering wheel, or (3) the hand is off the steering wheel and a weight is applied to the steering wheel, and actuate a steering subsystem when the output of the machine learning program indicates that the hand of the occupant is off the steering wheel.

Abstract: Disclosed are techniques pertaining to wireless dongles that can wirelessly transfer multimedia data (e.g., video and/or audio) between two computer devices. The computer devices can include a source (e.g., a laptop or tablet computer) and a sink (e.g., a television set or projector). The techniques improve the usability and flexibility of such dongles, allowing them to operate with a wide variety of devices.

Abstract: A method for establishing a location anchor network includes receiving, by a location application executing on a processor, GPS positions from each of the plurality of location anchors, determining, by the location application, a preliminary network topology using the GPS positions for each of the plurality of location anchors, receiving, by the location application, an inter-location anchor spacing between the plurality of location anchors, determining, by the location application, a final network topology based on the GPS position and the inter-anchor spacing, and storing the final network topology in a memory. The plurality of location anchors are portable, and the plurality of location anchors are deployed at a location associated with a structure. The final network topology defines a position estimate for each location anchor of the plurality of location anchors.

Abstract: A multilayer pet toy has an inner structure having an inner-structure resilient material; an outer structure joined to the inner structure, the outer structure having a first layer having a first sandwich structure, the first sandwich structure having an outer-structure resilient material and a non-resilient material. Therein, the inner structure resilient material includes a first rubber compound that has a percentage of 30% or less by weight of natural rubber and a remainder being filler. The outer-structure resilient material includes a second rubber compound that has a percentage of 44% or more by weight of natural rubber and a remainder being filler.
