Energy loads, sources or batteries exchange mathematical models with each other to form clusters of devices that together provide a service (self-reliance, frequency control, etc.) to a grid operator. Models are exchanged before or after forming clusters; a particular model is used to control its own device and is also used by another load/source to influence its control policy. Heuristics and an optimization technique (using models) are used to form a cluster of devices. Exchanging models obviates the need for a central entity to directly control loads/sources, and the need to exchange real-time data between loads/sources, providing resilience against communication failure. A service manager (demand-response aggregator) sends a service or technical constraints to loads/sources to form clusters on their own. Negotiation between manager and clusters occurs to form consensus on a response. Each device in a cluster is controlled by its own control policy which may depend upon the model of another device in the cluster. If communication is lost the clusters continue to implement the service.

An electronic gaming device is provided that allows a live player to compete against a virtual player in a multi-player wager-based game using playing cards derived from the insertion of a physical denomination of currency. The electronic gaming device can be configured to simulate the decision making of a virtual player and associated behaviors of the virtual player during game play. In some instances, the simulated behaviors of the virtual player output at the electronic gaming device can be learned by a live player so that the live player can make better or more advantageous game play decisions. The simulated behaviors of the virtual player can be conveyed to the live player via visual images, such as simulated facial expressions of the virtual player.

A method of playing a modified electronic version of roulette includes providing an executable instruction set hosted on a gaming system having a central server system, a random number generator, a database connected to an electronic network and at least one display for presenting to a player a representation of a roulette wheel, a roulette betting table, and a bet acceptance display for placing bets. A player's bet is placed, and a random number is selected and associated to one of a field of numbers on the betting table representation as the winning number. The winning and losing bets are determined and the winning number is removed from the field of numbers on the betting table. The removed number is replaced with a randomly selected one of the numbers remaining in the field of numbers on the table and the odds of each possible bet are recalculated.

A system for authorizing a financial transaction of a financial presentation device such as a credit or debit card being presented from a customer to an online merchant. The system includes a peripheral device having a processor configured to generate a dynamic verification value for the card which changes for each financial transaction, and to transmit the dynamic verification value to a user computer via an I/O interface during an online transaction. The system also includes an authentication computer having a memory for storing information used to generate a comparison verification value, a communication device for receiving the dynamic verification value originating from the peripheral device, a processor and an authentication module executable by the processor adapted to generate the comparison verification value using information stored in memory. The authentication computer determines whether to authorize the financial transaction based on whether the comparison verification value matches the received dynamic verification value.

Systems and methods for preventing spoofing of vehicle identification number (VIN) provisioning service. The system includes a memory that stores instructions for executing processes for preventing spoofing of vehicle identification number (VIN) provisioning service. The system also includes a processor configured to execute the instructions. The instructions cause the processor to receive enrollment information including a VIN and a hardware identifier for enrollment in a provisioning service for a vehicle. The instructions also cause the processor to verify whether the VIN is associated with the hardware identifier. The instructions further cause the processor to transmit a message to the vehicle based on the verification of the VIN being associated with the hardware identifier.

Computing devices for authoring content in computer-based 3D environments are disclosed herein. In one embodiment, a computing device is configured to provide, on a display, a user interface of a 3D authoring application having a 3D working area with a predefined shape and size. The computing device is also configured to, in response to receiving a user input selecting a 3D component, retrieve one or more files of the 3D component containing data that is pre-processed according to the predefined shape and size of the 3D working area. Based on the retrieved data of the 3D component, the computing device can produce (i) a graphical representation of one or more objects or (ii) a sound in the 3D working area without modifying, outside of the 3D authoring application, underlying data of the one or more objects or sound.

A redundant tracking system comprising multiple redundant tracking sub-systems, enabling seamless transitions between such tracking sub-systems, provides a solution to this problem by merging multiple tracking approaches into a single tracking system. This system is able to combine tracking objects with six degrees of freedom (6DoF) and 3DoF through combining and transitioning between multiple tracking systems based on the availability of tracking indicia tracked by the tracking systems. Thus, as the indicia tracked by any one tracking system becomes unavailable, the redundant tracking system seamlessly switches between tracking in 6DoF and 3DoF thereby providing the user with an uninterrupted experience.

The present disclosure relates to an automatic three-dimensional solid modeling method and program based on a two-dimensional drawing, including at least: acquiring a drawing image; generating a figure by extracting line segments in the drawing image; identifying sub-areas within the figure and identifying spatial types of the sub-areas; and generating a three-dimensional space model by applying height information corresponding to the spatial types of the sub-areas. The present disclosure is convenient in that there is no need to visit the real three-dimensional space in order to implement the corresponding space on a computer, and can remarkably reduce the time required to implement the three-dimensional space.
