Abstract: Rubber compounds with increased resistance to fire are disclosed. The rubber compounds are incorporated into fire seals and in particular into fire seals for aerospace applications. The advance rubber compounds are created by adding a powdered vitreous or glass material in combination with a fiber such as carbon fiber, with or without intumescent material to a base rubber compound and then curing.

Abstract: A ground-based node of a satellite system operates by: communicating control data with LEO navigation satellites in LEO around the earth; transmitting corrections data to the LEO navigation satellites; receiving a first collection of observations based on signaling from non-LEO navigation satellites in non-LEO around the earth, the signaling including collected observations from the non-LEO navigation satellites; receiving a second collection of observations based on navigation messages from the LEO navigation satellites, wherein the navigation messages facilitate client devices to determine their enhanced position when received in conjunction with second signaling from the non-LEO navigation satellites, and wherein the navigation messages are generated by the LEO navigation satellites in response to the corrections data; updating the corrections data based on the first collection of observations, the second collection of observations and based on telemetry data corresponding to the LEO navigation satellites

Abstract: Methods and apparatus for accelerating transforms via sparse matrix operations. Conventional processing architectures use bit-reversed addressing and a “butterfly” operation to perform digital signal processing techniques (such as the FFT, DFT, DCT, etc.). However, bit-reversed addressing may also be performed as a single sparse matrix permutation; similarly, butterfly operations may also be represented as a number of multi-matrix multiplications. Exemplary sparse matrix processors can perform these operations locally with great efficiency. Importantly, instead of sending data from a machine learning (ML) co-processor to a DSP to perform signal processing functions (and then back to the ML co-processor); the entire sequence may be performed on a sparse ML processor. This may greatly improve system power consumption and may entirely obviate the need for a separate DSP in certain (e.g., embedded) systems.

Abstract: Methods and apparatus for localized processing within multicore neural networks. Unlike existing solutions that rely on commodity software and hardware to perform “brute force” large scale neural network processing the various techniques described herein map and partition a neural network into the hardware limitations of a target platform. Specifically, the various implementations described herein synergistically leverage localization, sparsity, and distributed scheduling, to enable neural network processing within embedded hardware applications. As described herein, hardware-aware mapping/partitioning enhances neural network performance by e.g., avoiding pin-limited memory accesses, processing data in compressed formats/skipping unnecessary operations, and decoupling scheduling between cores.

Abstract: Disclosed herein are pigments comprising mostly rutile TiO2, wherein the mostly rutile TiO2 consists essentially of low abrasion TiO2 particles produced by introducing a metal halide into the chloride process.

Abstract: A means of constructing water filtration and treatment products that fill rapidly without pressure, and freely dispense the treated water simply by the force of gravity. The means used to treat the water is by static filtration applying highly porous media which occupies all or a significant segment of the container of the product. The water is retained within the container in direct and constant contact with the treatment media thus providing residence time beyond the capability of other filtration technologies in similar size and types of containers, with numerous advantages over standard water filtration products.
