Abstract: The method of this invention provides a simple and inexpensive method for manufacturing self-sealing pneumatic rubber tires of the tubeless type having a higher degree of uniformity than can be made utilizing conventional manufacturing procedures that are currently being practiced. In the practice of this invention a low viscosity sealant formulation, which would ordinarily be difficult to handle and build into an uncured tire, is encapsulated in a stiff rubber formulation. This makes it relatively easy to build the sealant layer into the tire since the low viscosity sealant formulation is contained with the more rigid solid material. The low viscosity sealant material requires little and preferably no depolymerization to act effectively as a sealant. Accordingly, it does not need to be depolymerized with a peroxide which causes off-gassing and the resultant tire uniformity and balance issues normally associated with polymer break down.

Abstract: Within an indoor setting and upon a floor-based mobile platform, exists one servomotor-controlled IR distance measuring sensor, while some distance away exists a passive and fixed reflector. The IR sensor operates to acquire and track the fixed reflector, the relative bearing of such defining navigation by a single reference point with obstacle detection.

Abstract: A system and method for a patent search and analytics software tool that finds prior art for each claim limitation/element by breaking up claims into individual claim limitations. Once the claims are separated, the system finds the best prior art for each of the individual separate, different claim limitations/elements. Additionally, the software finds the best prior art for entire claims, including non-patent literature (NPL) searching. The system takes into account the limitations of the claim under consideration (query claim of query patent), the text of the art, the link structure of the citation network, and the patent classification and then constructs a network that consists of two types of nodes: (i) the art (patents and non-patent literature) and the (ii) classes of the patent classification. Each art node is linked to all the art nodes that it cites and is linked to all the classification nodes that it belongs to.

Abstract: Systems, methods, tangible non-transitory computer-readable media, and devices for autonomous vehicle operation are provided. For example, a computing system can receive object data that includes portions of sensor data. The computing system can determine, in a first stage of a multiple stage classification using hardware components, one or more first stage characteristics of the portions of sensor data based on a first machine-learned model. In a second stage of the multiple stage classification, the computing system can determine second stage characteristics of the portions of sensor data based on a second machine-learned model. The computing system can generate an object output based on the first stage characteristics and the second stage characteristics. The object output can include indications associated with detection of objects in the portions of sensor data.

Abstract: A mobile or desktop application and associated system that provides a centralized storage platform for users to motivate the users to capture, organize, and/or share the user's own achievements over time is described herein. As one example, the users may be students, and the centralized storage platform may motivate such users to capture, organize, and/or share the user's own achievements over time in preparation for college admissions or employment (e.g., trade-based employment, college graduate employment, etc.).

Abstract: A creep resistant material comprises a core layer (12) of rigid polyurethane with a first tensile reinforcement layer (17) applied on one surface and a second tensile reinforcement layer (17) applied on the other opposed surface of the core layer, the entire respective first and second tensile reinforcement layers being in contact with the first and second surface of the core layer of the material.

Abstract: A system for detecting leaks is provided comprising an accumulator, a flow controller in communication with the accumulator, and a flow meter/sensor in communication with the accumulator, the flow controller and a UUT. The flow meter is structured to supply gas from the accumulator to the UUT and measure a flow rate of the supplied gas, the flow meter providing feedback to the flow controller representing the flow rate, and the flow controller responding to the feedback by supplying flow compensation gas to the accumulator to maintain a desired pressure in the accumulator. Methods are also provided for detecting small leaks, especially with large units under test (“UUTs”).
