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.

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.

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.

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.

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.

In one embodiment, the incident angle of the long-wavelength focused X-ray is ?24°, and the sample area is ?25 ?m×25 ?m.
