US11568203B2 Failed and censored instances based remaining useful life (RUL) estimation of entities
Estimating Remaining Useful Life (RUL) from multi-sensor time series data is difficult through manual inspection. Current machine learning and data analytics methods, for RUL estimation require large number of failed instances for training, which are rarely available in practice, and these methods cannot use information from currently operational censored instances since their failure time is unknown. Embodiments of the present disclosure provide systems and methods for estimating RUL using time series data by implementing an LSTM-RNN based ordinal regression technique, wherein during training RUL value of failed instance(s) is encoded into a vector which is given as a target to the model. Unlike a failed instance, the exact RUL for a censored instance is unknown. For using the censored instances, target vectors are generated and the objective function is modified for training wherein the trained LSTM-RNN based ordinal regression is applied on an input test time series for RUL estimation.
US11568196B2 Memory card and terminal
A memory card and a terminal, where the memory card includes a storage device, a controller, and a memory card interface. The storage device and the controller are disposed inside a card body of the memory card. The memory card interface is disposed on the card body of the memory card. The controller is electrically coupled to the storage device and the memory card interface separately. Because a shape of the memory card is the same as that of a nano subscriber identity module (SIM) card, and a size of the memory card is the same as that of the nano SIM card, a nano SD card is provided.
US11568192B2 Multilayer chip component
In a multilayer chip component according to an aspect of the present disclosure, dots of a two-dimensional code provided on a main surface of an element body has a semicircular cross-sectional shape. That is, since substantially no corner portions are present in a cross-sectional shape of the dots, stress is unlikely to remain when the dots are formed, and stress is unlikely to be concentrated after the dots are formed. Therefore, cracking is unlikely to occur in the foregoing multilayer chip component.
US11568182B2 System and method for 3D blob classification and transmission
Embodiments described herein provide an apparatus comprising a processor to project and accumulate three-dimensional (3D) point data from a blob onto a plane; construct a histogram of the 3D point data; identify a center of mass of the blob based on histogram data; surround peaks in coordinates for data in the blob with a shape defined by a diameter of the blob based on the center of mass; obtain height data for the 3D point data; and calculate dimensions for a bounding box to surround the blob based on the shape and the height data. Other embodiments may be described and claimed.
