Abstract: A collaborative security management system and methods are presented. The system includes a processor communicating with two or more user devices and memory communicating with the processor. The memory stores instructions that when executed result in the processor storing two or more data structures in memory. Each data structure includes secured information. The processor establishes at least one safe associated with the data structures and defines security rules for the safe. Each rule governs one of an access and an operations privilege. The access privilege grants or denies access to the safe by the user devices via an interface. The operations privilege enables or disables performance of operations upon the safe initiated by the user device from the interface. The processor controls, by the security rules, at least one of access to and operations performed upon the safes and data structures associated therewith by the user devices.

Abstract: An electric grill comprises a heating platform, side walls, and grill bars spaced above the heating platform, together defining a heating chamber. The heating platform is heated electrically. A first air supply delivers pressurised air evenly across the heating platform from a central location. A second air supply directs airflow along the side walls to create a vortex of air flowing around the first air supply. The forced airflow provides for fuller combustion of fats and oils from foodstuffs being cooked so that no fat tray is required.

Abstract: Systems and methods for training AV models in accordance with embodiments of the invention are illustrated. One embodiment includes an autonomous vehicle (AV), a vehicle, a processor, and a memory, where the memory contains an AV model capable of driving the vehicle without human input, where the AV model is trained on a plurality of edge case scenarios. In a still further additional embodiment, a method for training AV models, including obtaining a data structure storing a plurality of scenarios that an AV can encounter, and distance metrics indicating the distance between each scenario, generating a list of edge case scenarios within the plurality of scenarios, identifying hazard frames within the edge case scenarios, encoding the hazard frames into one or more records interpretable by an AV model, and training the AV model using the one or more records.

Abstract: Cooking apparatus for cooking food by a barbecue grilling method, comprises an outer housing receiving an inner housing which defines a heating volume. A chamber for pressurised air is defined between the outer and inner housings. Apertures in the inner housing allow pressurised air to exit the chamber into the heating volume. At least one burner is located in the inner housing. A combustible fuel/air mixture is supplied to the burner and this is separate from the supply of pressurised air to the chamber. A cooking surface is placed across the top of the heating volume to support food to be cooked.

Abstract: There is set forth herein in one embodiment, a structure including a metallic grating having a grating pattern, the metallic grating including a critical dimension. The metallic grating can output a spectral profile when exposed to electromagnetic radiation, the spectral profile having a feature. The grating pattern can be configured so that a change of the critical dimension produces a shift in a value of the feature of the spectral profile. A method can include propagating input electromagnetic radiation onto a metallic grating having a two dimensional periodic grating pattern and measuring a critical dimension of the metallic grating using output electromagnetic radiation from the metallic grating.

Abstract: A drawer for an airline trolley, which has a generally rectangular tray, is closed by a lid. The lid has a flap which is openable, and the drawer has a lock unit with which the flap engages. The lock unit is lockable by a breakable seal. The flap can be hinged about a line extended across the lid at a position forward of the back of the tray. The flap can be connected to the sides of the tray by webs which fold under the flap in its closed position, the webs preventing access to the interior of the tray under the lid. The flap can have a catch at its forward end which engages in a lockable chamber on the front of the drawer, a breakable seal being insertable into the chamber to engage the catch.

Abstract: Embodiments of the invention relate to a system, method, computer product, computer system and device for providing a live broadcast, the method includes receiving a first audio content; determining a first video content that matches the first audio content; matching the first video content with the first audio content in real time, forming matched first audio/video content; and providing the matched first audio/video content in the live broadcast. The method further includes receiving a second audio content; determining a second video content that matches the second audio content; matching the second video content with the second audio content in real time, forming matched second audio/video content; and providing the matched second audio/video content in the live broadcast.

Abstract: A gypsum stucco composition comprising the following components finely divided; calcium sulphate hemihydrate in calcined solid beta crystalline form; and in intimate mixture with said finely divided calcium sulphate hemihydrate and mixed therewith no later than calcination to form the hemihydrate, a sulphate salt comprising at least one of ammonium sulphate and aluminium sulphate, in an amount such that when the stucco composition is mixed with water and allowed to set, the resulting set plaster has increased compressive strength, flexural strength and/or E-modulus compared to a set plaster produced from said finely divided calcium sulphate hemihydrate containing no said sulphate salt.

Abstract: Devices and methods using wireless or wired network communications to form cooperative alarm networks centered on themselves. Intrusion detection alarms broadcast signals notifying other intrusion detection alarms of its status. When an alarm system experiences a security event, such as an attempted break-in, it notifies its network of its security event and other alarm systems within a cooperative network commence security measures, such as honking horns and flashing headlights. The cooperative response of the networked alarm systems increases decibel level and, in turn, the likelihood of a deterrent intervention, such as the perpetrator being apprehended, as well as increases the deterrence capability of the alarm systems.

Abstract: Methods and apparatus are provided for controlling temperatures in the environments of oil, gas condensate, or gas wells. Methods are provided for reducing the melting of glaciers and ice dams through the deployment of hydrate-forming substances. Active methods involve employing a vapor-compression refrigerator/heat pump cycle in an annulus lying between the relatively hot production string and the relatively cold outer pipe. Passive methods include: deploying cold hydrate-forming fluids into the external ice-laden environment of an oil, gas condensate, or gas well in a permafrost area and allowing those hydrate forming fluids to mix with any melt-water that may be present or that may subsequently form due to the loss of heat from the oil, gas condensate, or gas well. Mixtures of the hydrate forming fluids and the melt-water will set up into a solid having a much higher melting point and a much lower thermal conductivity than those of ice.
