Augmented reality dynamic authentication for electronic transactions
A system for authorizing an electronic transaction in an augmented reality environment comprises an augmented reality user device and an authentication server. The augmented reality user device includes a display that overlays virtual objects onto a field of view of the user. The user device receives a request to verify information about a payment card used in an electronic transaction. The request includes a virtual authentication object, which is a virtual representation of an object capable of being manipulated by the user in a particular sequence to enter an authentication code. The user device displays the virtual authentication object to the user and detects gestures performed on the virtual authentication object. The user device sends the detected gestures to the authentication server. The authentication server determines the authentication code using the virtual authentication object and the detected gestures, and uses it to authorize the transaction. |

Techniques are disclosed for managing a high performance, fault-tolerant, strongly consistent, distributed key-value store system. The key-value store may store information, such as metadata for a distributed file system.

Adapting transmitter training behavior based upon assumed identity of training partner
The present disclosure generally relates to reducing time for interface transmitter training based upon an assumed identify of the training partner. It is unlikely for a drive PHY to link up with multiple PHYs per power cycle. Therefore, it is a fair assumption that when there is no power loss, the drive PHY is connected to the same host device. The drive can therefore change its behavior based on the assumed identity of the host from previously exchanged identify frames, if the previously used training algorithm was sufficient for interface transmitter training for the particular host. The drive will go directly to the correct training algorithm without the need to do a PHY reset using a training algorithm that is tailored to the host and thus reduce interface transmitter training time. |

A tile of an FPGA provides memory, arithmetic functions, or both. Connections directly between multiple instances of the tile are available, allowing multiple tiles to be treated as larger memories or arithmetic circuits. By using these connections, referred to as cascade inputs and outputs, the input and output bandwidth of the arithmetic and memory circuits are increased, operand sizes are increased, or both. By using the cascade connections, multiple tiles can be used together as a single, larger tile. Thus, implementations that need memories of different sizes, arithmetic functions operating on different sized operands, or both, can use the same FPGA without additional programming or waste. Using cascade communications, more tiles are used when a large memory is needed and fewer tiles are used when a small memory is needed and the waste is avoided. |

The heating plate includes an electric heating conductor as the heat source and a temperature controller electrically connected with the heating conductor, sensing the temperature of the cooking vessel, controlling the heating plate output power, and limiting the temperature of the cooking oil in the cooking vessel. With this heating plate, the electric cooking apparatus will be able to prevent cooking oil ignition during cooking, while the minimum cooking temperature for a daily cooking is still maintained. |

Low-profile exhaust and air intake system for a direct vent fireplace
An exhaust and air intake system for a direct vent fireplace. A low-profile manifold assembly is coupled to a direct vent fireplace and is configured to receive exhaust gases from the fireplace and expel the exhaust gases outside of the building in which the fireplace is located. The manifold assembly also takes in fresh air from outside of the building and provides the fresh air to the fireplace to use during combustion. The manifold assembly includes separate chambers for the exhaust gases and the fresh air so that the exhaust gases and the fresh air do not mix together within the manifold assembly. Several pressure reduction and equalization structures are incorporated into the manifold assembly to regulate the amount and pressure of fresh air provided to the fireplace. |

Non-bypassable catalyst assisted appliances
A non-bypassable catalyst assisted appliance includes, for example, a housing having a combustion chamber, a loading door, an air inlet opening, and an exit opening connectable to a flue. A platform defines a non-movable separation in the housing between the combustion chamber and the exit opening. An insulated catalyst combustor is disposed between a top wall of the housing and the platform. When the door of the appliance is closed, gas from the combustion chamber is exhausted and directed along a single flow path horizontally through the insulated catalytic combustor and into the flue. When the door of the appliance is open, gas from the combustion chamber is inhibited from passing through the loading door opening, and ambient air entering the loading door opening and combustion gas from the combustion chamber are exhausted and directed along a single flow path horizontally through the insulated catalytic combustor and into the flue. |

Method for operating a gas burner appliance
In an example method for operating a gas burner appliance, during burner-on-phases, a gas/air mixture having a defined mixing ratio of gas and air is provided to a burner chamber. The gas/air mixture is provided by a mixing device that mixes an air flow with a gas flow. The air flow is provided by a fan in such a way that the fan speed of the fan depends on a desired burner load. During burner-on-phases, the combustion quality is monitored on the basis of a signal provided by a combustion quality sensor. The defined mixing ratio of gas and air of the gas/air mixture can be calibrated on the basis of the signal provided by the combustion quality sensor. |
