There is provided a gaming system, gaming machine, and method that presents a plurality of symbols in an array corresponding to a plurality of symbol-bearing reels. Game-logic circuitry positions a persistent symbol at a first symbol position in the array. Using a random number generator, the game logic-circuitry spins and stops the reels. Concurrently with the moving of the reels, the game-logic circuitry moves the persistent symbol from the first symbol position in the array to a second symbol position in the array. The game-logic circuitry moves the persistent symbol in a direction toward a win zone outside of the array. The game-logic circuitry further determines whether a catalyst symbol appears in the win zone. In response to determining that the catalyst symbol appears in the win zone, the game-logic circuitry awards a value associated with the persistent symbol.

A random number generator including: a first ring oscillator including a first inverter chain, the first inverter chain including a plurality of serially connected first inverters, the first ring oscillator configured to output a first random signal generated at a first sub-node between two neighboring first inverters among the plurality of first inverters; a second ring oscillator including a second inverter chain, the second inverter chain including a plurality of serially connected second inverters, the second ring oscillator configured to output a second random signal generated at a second sub-node between two neighboring second inverters among the plurality of second inverters; and a signal processing circuit for generating a random number by combining the first random signal with the second random signal.

Technologies are provided for reformulation of a tail query to a head query with the same purchase intent by mapping the tail query to the head query. In some of the technologies, a reasonable embedding can be learned on historical head queries. The embedding can then be refined by leveraging rewards generated from a persistently noisy oracle that compensates for the lack of historical behavioral signal for tail queries. Further, a contextual sampling technique that uses text-based rewards or oracle-based rewards, or both, can be implemented in order to avoid biases introduced by persistent noise in the oracle. Numerical experiments on large scale e-commerce datasets demonstrate that the provided technologies can outperform several conventional approaches to query reformulation.

A random number generator includes a ring oscillator, an inversion selecting circuit, and controller. The ring oscillator includes an inverter chain having at least one inverter and generates an output signal. The inversion selecting circuit controlling a phase inverter configured to invert a signal of the inverter chain. The controller is configured to operate the inversion selecting circuit to provide an output of the first phase inverter to the inverter chain during a first operation mode to measure a frequency of the ring oscillator and operate the inversion selecting circuit to not provide the output of the phase inverter during a second operation mode for generating a random number.

An electronic gaming machine includes a display device, a player input interface configured to receive player input from a player; and a game controller configured to execute instructions. The instructions cause the processor to display a plurality of game reels including a first game reel type having a plurality of symbol positions and a second game reel type including a grouped symbol position. The instructions also cause the processor to display a bonus symbol in the grouped system position and, in response to displaying the bonus symbol, to display an expanded display area comprising at least one additional symbol position located above the reels of the first game reel type. The instructions further cause the processor to determine a game outcome based upon a combination of the at least one additional symbol position and the plurality of symbol positions.

A gaming device having a processor that selects symbols from a first set of reel strips for a plurality of columns of symbol positions, and from a second set of reel strips for a plurality of columns of symbol positions, and controls a display to display the symbols selected including displaying, at each symbol position for which a defined symbol is selected, the defined symbol with the symbol selected at a respective symbol position. Upon the symbols selected including a qualifier symbol, the processor randomly selects one of at least two different symbol replacements, and determines, using the symbol replacements, a replacement symbol for the defined symbol selected. The processor updates the plurality of symbols to incorporate the replacement symbol, and evaluates the updated plurality of symbols for winning symbol combinations.

The invention relates to a method for operating a memory assembly. A physical address is received. The physical address is associated with a first memory segment of a memory assembly. The physical address is modified to a modified physical address. The modified physical address is associated with a second memory segment of the memory assembly.

A slot game may assign a multiplier value to a stacked reel having an outcome including a stack of special symbols or wild symbols. The assigned multiplier value may be selected based on a random game outcome of preceding reels. The slot game may display the stacked reel with the assigned multiplier value or by replacing the stack of special symbols with a single symbol and the assigned multiplier value. The slot game may display a merged multiplier value over adjacent stacked reels, the merged multiplier value being the product of the assigned multiplier values for each of the adjacent stacked reels.

A system and a method for a supply-chain hardware integrity for electronics defense (SHIELD) dielet embedded over a component of a device, a radio frequency identification (RFID) probe system coupled to the SHIELD dielet, and a secure server system communicating with the RFID probe system that can enable security services is provided. Embodiments include a multi-function SHIELD software defined, hardware enabled security system that provides hardware identity, anti-tamper, encryption key generation and management, trusted platform module services, and cryptographic software security services for a device.

A storage device and a data access method are provided. The storage device includes a primary storage unit and at least one additional unit. The primary storage unit includes: a primary memory element configured to store secret data and a primary access unit configured to receive an external access command. Each additional unit is configured to receive the external access command. Each additional unit includes: an additional memory element configured to store non-specific data, a local access generation element configured to trigger generating an internal access command based on the external access command, and an additional access unit configured to receive a local access command. The primary storage unit and each additional unit are coupled to a same power rail and a connection wire to simultaneously receive the external access command to parallelly (simultaneously) access the secret data and the non-specific data stored in each additional unit.
