  • Publication number: 20240062334
    Abstract: A fluorescent single molecule emitter simultaneously transmits its identity, location, and cellular context through its emission patterns. A deep neural network (DNN) performs multiplexed single-molecule analysis to enable retrieving such information with high accuracy. The DNN can extract three-dimensional molecule location, orientation, and wavefront distortion with precision approaching the theoretical limit of information content of the image which will allow multiplexed measurements through the emission patterns of a single molecule.

  • Publication number: 20240053153
    Abstract: A device operates in pairing mode, indoor navigation mode or search mode. For each mode, a magnetic sensor in the device senses one or more alternating current (AC) magnetic fields emitted by one or more transmitters in a three-dimensional (3D) space, and uses the one or more AC magnetic fields to determine a position of the device relative to the one or more transmitters or another device. In pairing mode, relative position vectors computed from two or more AC magnetic fields allows the device to choose the closest transmitter for pairing. In indoor navigation mode, multiple detections of AC magnetic fields emitted by multiple transmitters assist a user in navigating an indoor space. In search mode, a companion device and a lost device each sense an AC magnetic field from a transmitter, and he AC magnetic fields are used to determine a relative position vector from the companion device to the lost device.

  • Publication number: 20240038682
    Abstract: A laser grooving operation is performed to form a plurality of grooves in a semiconductor die prior to attaching the semiconductor die to a semiconductor device package substrate. In addition to forming a first groove through which blade sawing is to be performed to separate the semiconductor die from other semiconductor dies, a second groove may be formed between the first groove and a seal ring of the semiconductor die. The second groove is configured to contain any potential delamination that might otherwise propagate to an active region of the semiconductor die. Accordingly, the second groove and the associated laser grooving operation described herein may reduce the likelihood of delamination that might otherwise be caused by swelling and/or expansion in a molding compound formed around the semiconductor die after the semiconductor die is attached to the semiconductor device package substrate.
