Methods for more efficiently managing a buffer by controlling the threshold based on the length of delay line instructions are disclosed. Methods for disposing multi-type and multi-size operations in hardware are disclosed. Methods for condensing look-up tables are disclosed. Methods for in-line alteration of variables are disclosed.

Abstract: A system, apparatus, and method to identify incentives in multi-party interactions where such incentives are represented by specification value pairs and through the use of game theory, machine leaning, pattern identification and recognition and/or digital twins in any arrangement, misalignment of such specification value pairs may be identified and responded to in manner that can avoid and/or mitigate the impact of such misalignments on the interactions of those parties, including in pursuit of the reduction of fraud or other undesirable behaviors within at least one system.

Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to improve convolution efficiency of a convolution neural network (CNN) accelerator. An example hardware accelerator includes a hardware data path element (DPE) in a DPE array, the hardware DPE including an accumulator, and a multiplier coupled to the accumulator, the multiplier to multiply first inputs including an activation value and a filter coefficient value to generate a first convolution output when the hardware DPE is in a convolution mode, and a controller coupled to the DPE array, the controller to adjust the hardware DPE from the convolution mode to a pooling mode by causing at least one of the multiplier or the accumulator to generate a second convolution output based on second inputs, the second inputs including an output location value of a pool area, at least one of the first inputs different from at least one of the second inputs.

Abstract: A filter assembly for an engine, has: a housing having a longitudinal axis and defining an internal volume, the housing having an open end; and a cartridge assembly receivable within the internal volume via the open end of the housing and securable to the housing, the cartridge assembly including a filter cartridge, a cover removably secured to the filter cartridge, and a sealing member between the cover and the filter cartridge, a locking engagement between the cover and the filter cartridge to limit an axial movement of the cover relative to the filter cartridge upon removal of the cartridge assembly from the housing.

Abstract: An assembly for a gas turbine engine having: static and rotating components; a seal between the static and rotating components, and between a cavity and an environment outside thereof, the cavity having an inlet fluidly connectable to a source of lubricant and an outlet fluidly connectable to a scavenge pump for drawing lubricant out of the cavity; and a drain conduit having a drain inlet outside the cavity in proximity to the seal for receiving leaked lubricant, and a drain outlet fluidly connected to the outlet of the cavity, the drain outlet located in proximity to a scavenge inlet via which the lubricant exits the cavity to flow toward the scavenge pump such that, in use, a lubricant flow within the drain conduit is entrained by the lubricant exiting the cavity via the scavenge inlet.

Abstract: A method and system to verify identity while protecting private data. To locally verify identity without requiring communication with an external database or passing personal/identity information over network connections. To create a database and/or statistical model for later use to verify identify, private information from a first media is input to a device. Private information subsequently presented via a second media is then verified locally by comparing to the private information previously captured from the first media. If the resultant correlation score is sufficiently high the private information from the first media and from the second media are determined to belong to the same individual, and the user is authenticated or a desired action is approved. In case of a low correlation score, a notification may be sent to one or more entities alerting authorities of a security breach or identity theft.
