Rendering augmented reality with occlusion
AR elements are occluded in video image frames. A depth map is determined for an image frame of a video received from a video capture device. An AR graphical element for overlaying over the image frame is received. An element distance for AR graphical elements relative to a position of a user of the video capture device (e.g., the geographic position of the video capture device) is also received. Based on the depth map for the image frame, a pixel distance is determined for each pixel in the image frame. The pixel distances of the pixels in the image frame are compared to the element distance, and in response to a pixel distance for a given pixel being less than the element distance, the pixel of the image frame is displayed rather than a corresponding pixel of the AR graphical element. |

Automated medication compliance assurance system
Provided is a system providing a solution for improving prescription drug compliance monitoring and compliance. Prescription drug compliance monitoring may be achieved by using patient's electronic device to initiate secure digital imaging. Medications may be dispensed in containers with pre-printed encoded unique identifiers and markings. The patient may use the digital camera in their smart phone to take a picture of the dispensed blister pack which may be processed and analyzed. Analysis may include assessment of the number of pills taken from and remaining in the uniquely identified blister pack. Package identification and consumption information may then be linked with other prescription information to determine if the observed rate of use is compliant with the legal prescription and to document that the imaged medication package is the same as the dispensed medication package. Data may also be linked with pharmacologic and clinical data to categorize risk and urgency of misuse. |

Memory device and method of operating the same
A memory device may include: memory cells each having any one of first and second programmed states as a target programmed state; a peripheral circuit configured to perform a program operation so that each memory cell has a threshold voltage corresponding to the target programmed state; and a control circuit configured to control the peripheral circuit. The control circuit may include a program operation controller configured to control the peripheral circuit so that, during the program operation, an intermediate program operation is performed on the memory cells using an intermediate verify voltage, an additional program operation is performed on memory cells each having the second programmed state as a target programmed state if an intermediate verify operation passes, and a final program operation is performed on the memory cells such that each memory cell has a threshold voltage corresponding to the target programmed state. |

PCRAM analog programming by a gradual reset cooling step
In some embodiments, the present disclosure relates a phase change random access memory device that includes a phase change material (PCM) layer disposed between bottom and top electrodes. A controller circuit is coupled to the bottom and top electrodes and is configured to perform a first reset operation by applying a signal at a first amplitude across the PCM layer for a first time period and decreasing the signal from the first amplitude to a second amplitude for a second time period; and to perform a second reset operation by applying the signal at a third amplitude across the PCM layer for a third time period and decreasing the signal from the third amplitude to a fourth amplitude for a fourth time period greater than the second time period. After the fourth time period, the PCM layer has a percent crystallinity greater than the PCM layer after the second time period. |

Memory device and method for writing data
A memory device includes a storage unit array and a controller. The storage unit array contains storage units arranged in M rows and N columns and has M word lines and N bit line pairs. Each of the N bit line pairs includes a bit line and a source line. In operation, after obtaining Q rows of data that are to be written into Q rows of storage units in the storage unit array, the controller writes a first value into each of storage units in a column j in P columns of storage units. The controller then determines to-be-written rows in the Q rows of data, and writes in parallel a second value into each of storage units of the to-be-written rows in the storage units in the column j. |

Non-volatile memory device including a row decoder with a pull-up stage controlled by a current mirror
An embodiment non-volatile memory device includes an array of memory cells, coupled to word lines, and a row decoder including a pull-down stage and a pull-up stage, which includes, for each word line: a corresponding control circuit, which generates a corresponding control signal; and a corresponding pull-up switch circuit, which is controlled via the control signal so as to couple/decouple the word line to/from the supply. The control circuit includes: a current mirror, which injects a current into an internal node; and a series circuit, which couples/decouples the corresponding internal node to/from ground, on the basis of selection/deselection of the corresponding word line so as to cause a decrease/increase in a voltage on the corresponding internal node. Each control signal is a function of the voltage on the corresponding internal node. |

Circuit and method of writing to a bit cell
A circuit includes a bit line, a pass gate coupled between the bit line and a power node having a first power voltage level, and a driver coupled between the bit line and a reference node having a reference voltage level. The pass gate couples the bit line to the power node when the first signal has the reference voltage level and decouples the bit line from the power node when the first signal has the first power voltage level. The driver receives a second signal based on a control signal, couples the bit line to the reference node when the second signal has a second power voltage level below the first power voltage level, and decouples the bit line from the reference node when the second signal has the reference voltage level. An input circuit generates the first signal independent of the control signal. |

Memory device
A memory device is disclosed, in which node contacts extend into a substrate, where they are come into electrical connection with active areas. This allows greater contact areas between the node contacts and the active areas and electrical connection of the node contacts with high ion concentration portions of the active areas. As a result, even when voids are formed in the node contacts, the node contacts can still possess desired connection performance. For node contacts allowed to contain voids, this enables them to be fabricated faster with lower difficulty, thus increasing manufacturing throughput of the memory device. |
