Abstract: Systems and methods for updating metadata. In some embodiments, in response to detecting an instruction executed by a hardware system, a source location of the instruction may be identified. First metadata associated with the instruction may be used to determine whether the instruction is allowed. In response to determining that the instruction is allowed, the source location of the instruction may be associated with second metadata.

Abstract: A system including at least one processor programmed to identify, based on a policy to be enforced, one or more metadata symbols corresponding to an entity name; identify, from a target description describing a target system, an entity description matching the entity name, wherein the entity description describes an entity of the target system; and apply a metadata label to the entity of the target system, wherein the metadata label is based on the one or more metadata symbols corresponding to the entity name, as identified based on the policy.

Abstract: Systems and methods for metadata processing. In some embodiments, a target address may be received from a host processor. The target address may be used to access mapping information and decoding information, the mapping information and the decoding information being associated with the target address. The mapping information may be used to map the target address to a metadata address. The metadata address may be used to retrieve metadata, and the decoding information may be used to decode the retrieved metadata.

Abstract: In some embodiments, a system is provided, comprising enforcement hardware configured to execute, at run time, a state machine in parallel with application code. Executing the state machine may include: maintaining metadata that corresponds to one or more state variables of the state machine; matching instructions in the application code to transitions in the state machine; and, in response to determining that an instruction in the application code does not match any transition from a current state of the state machine, causing an error handling routine to be executed. In some embodiments, a description of a state machine may be translated into at least one policy to be enforced at run time based on metadata labels associated with application code and/or data manipulated by the application code.

Abstract: A system including at least one processor programmed to translate a policy into policy code, wherein: the policy is provided in a policy language; the policy code is in a programming language that is different from the policy language; and the policy includes a statement that maps an entity name to one or more metadata symbols to be associated with an entity in a target system against which the policy is to be enforced.

Abstract: Devices, systems, and methods are provided for synchronizing presentation across multiple devices. A method may include receiving, by a first device, a first price associated with a product and a first time, wherein the first price is presented in a virtual location. The method may include determining a second price and a second time, the second price associated with the product, wherein the second price is presented at a physical location. The method may include determining that the first time is after the second time. The method may include determining a difference between the first price and the second price. The method may include generating, based on the difference, one or more application programming interface (API) calls associated with replacing, at the physical location, presentation of the second price with presentation of the first price.

Abstract: A door breaching device includes a longitudinal chassis having a first extremity, a piston assembly with a piston rod adapted for linear displacement within a piston chamber, a hydraulic pump operatively connected to the piston assembly, and a two-part head assembly with a fixed jaw attached to the first extremity of the longitudinal chassis and a moveable jaw operatively connected to an end of the piston rod proximate to the first extremity. When the device is in a rest position, the piston rod is in a retracted position within the piston chamber to allow portions of the fixed jaw and the moveable jaw to fit between a first surface and a second surface. Upon actuation of the door breaching device, the piston rod is linearly displaced from the retracted position and the movable jaw applies a force to increase a distance between the first surface and the second surface.

Abstract: Systems and methods for efficient metadata processing, for example, by resolving input patterns into binary representations ahead of time. In some embodiments, a plurality of input patterns may be identified, wherein an input pattern of the plurality of input patterns comprises a metadata label. A plurality of respective values may be selected for a plurality of variables, wherein the plurality of variables comprise a variable corresponding to the metadata label of the input pattern. A binary representation of the metadata label may be obtained based on the respective value of the variable.
