  • Publication number: 20240028245
    Abstract: A memory apparatus and a data rearrangement method for computing in memory (CIM) are provided. The method includes determining whether first sequence data has two target bits that are both of a first value, inserting a non-target bit of a second value between the two target bits that are both of the first value and adjacent to each other to generate second sequence data, and receiving the second sequence data through memory cells in a memory to perform a multiply-accumulate (MAC) operation on the second sequence data. Each bit in the first sequence data is the first value or the second value. One of the two target bits is located adjacent to the other one of the two target bits in the first sequence data. The two target bits and the non-target bit are located in the first sequence data. Accordingly, the error rate is decreased.

  • Publication number: 20240028452
    Abstract: A data processing circuit and a fault-mitigating method are provided. A first data is written into a memory. A computed result is determined according to one or more adjacent bits of the first data at faulty bits. According to the computed result, new values are determined. The new values replace the values of the first data at the faulty bits to form a second data. The first data includes multiple bits. The first data is image-related data, weights used by a multiply-accumulate (MAC) for extracting features of images, and/or values used by an activation calculation. The adjacent bits are adjacent to the faulty bits. The computed result is obtained through computing the values of the first data at non-faulty bits of the memory. Accordingly, an influence of a memory fault is reduced.

  • Publication number: 20240028294
    Abstract: Aspects of the present disclosure are directed to quantitatively tracking food intake using smart glasses and/or other wearable devices. In some implementations, the smart glasses can include an image capture device, such as a camera, that can seamlessly capture images of food being eaten by the user. A computing device in communication with the smart glasses (or the smart glasses themselves) can identify the type and volume of food being eaten by applying object recognition and volume estimation techniques to the images. Additionally or alternatively, the smart glasses and/or other wearable devices can track a user's eating patterns through the number of bites taken throughout the day by capturing and analyzing hand-to-mouth motions and chewing. The computing device can log the type of food, volume of food, and/or number of bites taken and compute statistics that can be displayed to the user on the smart glasses.

  • Patent number: 11876527
    Abstract: An error calibration apparatus and method are provided. The method is adapted for calibrating a machine learning (ML) accelerator. The ML accelerator achieves computation by using an analog circuit. An error between an output value of one or more computing layers of a neural network and a corresponding corrected value is determined. The computation of the computing layers is achieved by the analog circuit. A calibration node is generated according to the error. The calibration node is located at the next layer of the computing layers. The calibration node is used to minimize the error. The calibration node is achieved by a digital circuit. Accordingly, error and distortion of the analog circuit could be reduced.

  • Publication number: 20240012364
    Abstract: Methods, systems, apparatuses, and computer program products are provided for enabling devices to determine the time zone in which they are located. A mobile device may receive location information from one or more sources. Based thereon, the current location of the mobile device may be determined in terms of latitude and longitude. The indication of the current location may be converted to an index value according to a Hilbert curve (or other space-filling curve), and the index value applied to a time zone index file to determine the local time zone. A time zone setting of the mobile device may be updated accordingly. Furthermore, “geofencing” may be used by the mobile device to detect movement towards and through a time zone boundary, leading to a new time zone determination being initiated.

  • Patent number: 11867595
    Abstract: This disclosure relates to an apparatus and methods for applying X-ray reflectometry (XRR) in characterizing three dimensional nanostructures supported on a flat substrate with a miniscule sampling area and a thickness in nanometers. In particular, this disclosure is targeted for addressing the difficulties encountered when XRR is applied to samples with intricate nanostructures along all three directions, e.g. arrays of nanostructured poles or shafts. Convergent X-ray with long wavelength, greater than that from a copper anode of 0.154 nm and less than twice of the characteristic dimensions along the film thickness direction, is preferably used with appropriate collimations on both incident and detection arms to enable the XRR for measurements of samples with limited sample area and scattering volumes. In one embodiment, the incident angle of the long-wavelength focused X-ray is ?24°, and the sample area is ?25 ?m×25 ?m.
