Abstract: Systems and methods that, responsive to an amount of a credit meter of a video lottery terminal being less than a designated amount and an occurrence of a credit meter contribution event, cause the video lottery terminal to reduce the amount of the credit meter, and modify, based on at least part of the reduced amount of the credit meter, an amount of a contribution pool maintained independent of the video lottery terminal. A probability of winning the amount of the contribution pool associated with the occurrence of the credit meter contribution event is independent of the reduced amount of the credit meter.

Abstract: Systems and methods that, responsive to an on-demand occurrence of a contribution event associated with a user selected amount at a video lottery terminal, communicate data that causes the video lottery terminal to reduce an amount of a credit meter by the user selected amount, and modify, based on at least part of the reduced amount of the credit meter, an amount of a contribution pool maintained independent of the video lottery terminal. The amount of the contribution pool is won independent of any displayed event occurring in any displayed play of any game at any video lottery terminal and a probability of winning the amount of the contribution pool associated with the occurrence of the credit meter contribution event is independent of the reduced amount of the credit meter.

Abstract: A gaming device includes a display device, an input device, a processor circuit, and a memory. The memory includes machine-readable instructions that, when executed by the processor circuit, cause the processor circuit to receive, by the processor circuit and via an operator processing circuit, identification corresponding to multiple game sets. Each of the game sets may include a subset of games. The processor circuit is caused to determine a recommended game set switch from a first game set to a second game set. The first and second game sets are on an electronic gaming machine (EGM) and the determining is performed using artificial intelligence that uses external data to identify the second game sets. The processor circuit is caused to transmit, to the EGM, an identification of the recommended game set switch.

Abstract: Systems and methods for computer memory management by a memory coordinator and a plurality of memory consumers. An urgency and memory quota of each memory consumer is initialized by the memory coordinator, which then adjusts the memory quota of each memory consumer such that the sum of the memory quota of each memory consumer does not exceed a finite amount of computer memory. Each memory consumer adjusts its memory usage in response to the quota input and urgency input from the memory coordinator.

Abstract: Commands in a command queue are received and scheduled. For each of the commands, scheduling includes determining an age of a command based on an entrance time of the command in the command queue. When the age of the command satisfies a first threshold, marking all other commands in the command queue as not issuable when the command is a deterministic command, and marking all other commands in the command queue as not issuable when the command is a non-deterministic command and the intermediate command queue is not empty. Scheduling the command further includes determining whether the command is a read command and marking the command as not issuable when the command is a non-deterministic read command and the intermediate command queue is empty.

Abstract: Embodiments of the present disclosure are directed to maintaining a self-versioning data lake. According to one embodiment, a method for providing access to a data lake can comprise maintaining a corpus of data in an initial version the data lake, monitoring versioning information for each of a plurality of schemas for data submitted to the data lake, and detecting a change in a schema of the plurality of schemas based on the monitoring of the versioning information for the plurality of schema. A new version of the data lake can be created based on the detected changes in the schema while maintaining the initial version of the data lake. A notification of availability of the new version of the data lake can be provided to users of the data lake.

Abstract: A system may include a memory and memory controller configured to communicate with the memory over two or more channels. The memory controller may have a buffer with buffer locations distributed across memory channels, and may be configured to receive a write command for writing current data to a memory location within the memory and may be configured to determine whether to buffer data and/or parity, and configured to write the current data or the current parity in the buffer when it is determined to be stored in the buffer. As the buffer is faster and uses less power, the reduction in back-end accesses improves performance and reduces power consumption.

Abstract: Systems and methods for finite time counting period counting of infinite data streams is presented. In particular example systems and methods enable counting row accesses to a memory media device over predetermined time intervals in order to deterministically detect row hammer attacks on the memory media device. Example embodiments use two identical tables that are reset at times offset in relation to each other in a ping-pong manner in order to ensure that there exists no false negative detections. The counting techniques described in this disclosure can be used in various types of row hammer mitigation techniques and can be implemented in content addressable memory or another type of memory. The mitigation may be implemented on a per-bank basis, per-channel basis or per-memory media device basis. The memory media device may be a dynamic random access memory type device.

Abstract: Systems and methods that provide a mechanism to transition static schema to dynamic schema while maintaining backwards capability. Simple removal of static schema elements, followed by replacement with dynamic schema elements, make a third-party code incompatible since the third-party code references schema entities that no longer exist. Provided is a mechanism to decrease the memory use of non-material static schema entities. Transitioning static schema to dynamic schema allows the database to avoid loading non-material schema entities, thereby decreasing overall memory usage.

After the tournament time period, the plurality tournament scores for the plurality of players are evaluated, and a tournament prize is awarded to a player of the plurality of players based on the evaluation of the tournament scores.

Abstract: A method and apparatus for inscribing a Bragg grating in the core of an optical waveguide. Electromagnetic radiation at a chosen wavelength passes through a diffractive optical element optimized for the wavelength such that a beam is generated on the waveguide having an interference pattern so as to form a Bragg grating in the core of the optical waveguide, the beam being sufficiently intense to cause a permanent (Type II) change in the index of refraction in the core in the form of at least one elongated micropore. The Bragg grating period can be selected to promote coupling of guided light into a radiation mode for detection by a detector to form a spectrometer. The Bragg grating is characterized by a scattering loss less than 10?5 dB per grating period at the Bragg resonance but outcoupling efficiency at visible wavelengths of 0.03% per grating period.

Abstract: A variety of applications can include memory or memory sub-systems having a memory-centric protocol with dedicated unidirectional serialized interfaces in the two directions of the interface for the memory or the memory sub-systems. The unidirectional serialized interfaces can be realized by dedicated pins on the devices connected by the devices. The memory-centric protocol with dedicated unidirectional serialized interfaces can support both deterministic and non-deterministic timed input/output to media and memory sub-systems.
