Abstract: A voltage-glitch detection and protection circuit and method are provided. Generally, circuit includes a voltage-glitch-detection-block (GDB) and a system-reset-block coupled to the GDB to generate a reset-signal to cause devices in a chip including the circuit to be reset when a voltage-glitch in a supply voltage (VDD) is detected. The GDB includes a voltage-glitch-detector coupled to a latch. The voltage-glitch-detector detects the voltage-glitch and generates a PULSE to the system-reset-block and latch. The latch receives the PULSE and generates a PULSE_LATCHED signal to the system-reset-block to ensure the reset-signal is generated no matter a width of the PULSE. In one embodiment, the latch includes a filter and a sample and hold circuit to power the latch, and ensure the PULSE_LATCHED signal is coupled to the system-reset-block when a voltage to the GDB or to the latch drops below a minimum voltage due to the voltage-glitch.

Abstract: A method and apparatus for video encoding/decoding are provided. In some examples, an apparatus includes processing circuitry for video decoding. The processing circuitry decodes prediction information of a block in a current picture from a coded video bitstream.

Processing I/O operations may include: receiving a write operation that writes data to a target logical address; determining a fingerprint for the data; querying the fingerprint hash table using the fingerprint to determine a matching entry of the fingerprint hash table for the fingerprint; and responsive to determining that the fingerprint hash table does not have the matching entry that matches the fingerprint, performing processing including: inserting a first entry in the fingerprint hash table, wherein the first entry includes the fingerprint for the data and identifies a storage location at which the data is stored; and inserting a second entry in a backend location hash table, wherein the second entry references the first entry.

Abstract: An intelligent assistant records speech spoken by a first user and determines a self-selection score for the first user. The intelligent assistant sends the self-selection score to another intelligent assistant, and receives a remote-selection score for the first user from the other intelligent assistant. The intelligent assistant compares the self-selection score to the remote-selection score. If the self-selection score is greater than the remote-selection score, the intelligent assistant responds to the first user and blocks subsequent responses to all other users until a disengagement metric of the first user exceeds a blocking threshold. If the self-selection score is less than the remote-selection score, the intelligent assistant does not respond to the first user.

The user's account balance is decreased, and simulated reels are spun. Adjustment arrows are displayed for a subset of the plurality of simulated reels. The player selects a simulated reel and a direction of adjustment for the simulated reel. If the player's adjustment creates a winning pattern, the user is rewarded with an increased account balance. The user may also be provided a bonus amount for achieving a number of consecutive wins.

Abstract: In some cases, signal attenuation may occur when a mobile device communicates with a vehicle. To accommodate for this, a vehicle may determine a distance between the vehicle and the mobile device by evaluating a signal strength of a wireless signal received from the mobile device. An erroneous distance result may be produced when the wireless signal is attenuated by an intervening object. A wearable device worn by the individual is used to detect the presence of the mobile device. The detection procedure involves measuring a separation distance between the wearable device and the mobile device at different instances in time as the individual swings his/her arm back and forth while moving towards the vehicle.
