Inventor: AHONEN MIKA
IPC: B24B7/22
Filed: 2019-09-03
Abstract: A method in dry shake coating of a concrete floor, whereby an applied floor concrete mass (B) is first of all subjected to early after-care, most preferably by spraying its surface with an early aftercare agent, in which connection, if necessary, after floating, on top of the floor concrete mass is applied a dry shake material (K) for two or more superimposed dry shake layers, in which connection the surface of a currently underlying dry shake layer is troweled prior to the application of a next dry shake layer to be processed thereupon, whereafter the lastly processed dry shake layer of a concrete floor is troweled and the concrete floor is subjected to actual aftercare with an aftercare agent, water spraying, plastic sheet, filter fabric protection, or the like. The application of an underlying dry shake layer (Kl) is followed by spreading over its surface a water soluble silica-based medium (V) prior to and/or during the course of troweling this particular dry shake layer and prior to the application of an overlying dry shake layer (K2) to be spread thereupon.

Title: Methods and systems for preauthenticating tokens issued by a client
Inventor: LEON FELIPE
IPC: H04L9/32
Filed: 2020-02-25
Abstract: Methods and systems for authorizing a service request between two services in a network environment are disclosed. One method includes, in a recurring background process occurring separate from a service request, having a target service obtain a pre-authorization token including a signature of the request service. In response to confirming the pre- authorization token was issued by the request service, the pre-authorization token is acknowledged and stored for access by instance(s) of the target service. The acknowledged pre-authorization token is saved for use with service requests to the target service from the request service. In response to receiving a service request including pre- authorization token at an instance of the target service,the method confirms the pre-authorization token matches a stored, acknowledged pre-authorization token, and, if so confirmed, authorizes the service request. Pre-authorization tokens have a set duration. The methods and systems reduce computational overhead of the authorization, resulting in decreased latency.

Title: Relative spatial localization of mobile devices
Inventor: POLLEFEYS MARC ANDRE LEON
IPC: H04W4/02
Filed: 2020-01-30
Abstract: To obtain a relative localization between a plurality of mobile devices, a first mobile device observes a second mobile device within a field of view of the first mobile device's camera at time t1, determines a first position of the first mobile device at t1, and receives from the second mobile device a second position of the second mobile device at t1. The first mobile device determines information about the first mobile device's orientation with respect to the second mobile device at t1 based at least in part on the first position and the observation of the second mobile device. The first mobile device identifies two constraints that relate the mobile devices' coordinate systems based at least in part on the second position and the orientation information. The first mobile device's pose relative to the second mobile device may be calculated once at least six constraints are accumulated.

Abstract: A method for obtaining a data segment, by a client device communicating with content delivery networks, is provided. The method involves calculating a score associated with a content delivery network indicative of a quality of transmission of data from the content delivery network to the client device. The score is based on a transmission error heuristic and transmission error is measured at a session layer or an application layer. A specific content delivery network is randomly selected so that a first probability of selecting the specific content delivery network associated with a first score indicative of a first quality of transmission is higher than another probability of selecting another content delivery network associated with a second score indicative of a second quality of transmission lower than the first quality of transmission. The selected network is required for the client device to obtain the data segment from the selected network.

Title: Smart dimming & sensor failure detection as part of built in ambient light harvesting inside the luminaire
Inventor: GURJAR RAVINDRA VIRAJ
IPC: H05B47/11
Filed: 2020-08-21
Abstract: A self-adjusting luminaire (100) whose primary operation is to provide ambient or focused lighting in a hazardous environment is configured to modify (e.g., continuously) the energization intensity levels of its on-board illumination sources (108a, 108n) based on magnitudes of difference between an amount of light in the environment of the luminaire (e.g., including both light produced by the luminaire and ambient light) as measured by on-board sensors (130) and a setpoint amount of light corresponding to the luminaire. Further, the self-adjusting luminaire may detect that its on-board sensors are malfunctioning when the illumination sensors fail to sense a change in the amount of light in the environment of the luminaire after the luminaire has modified the energization intensity levels of its illumination sources. Upon detecting a sensor malfunction, the self-adjusting luminaire may generate an alarm, and/or may automatically modify the intensity of its illumination sources to mitigate effects of the detected malfunction.

Title: Control of unsaturation in polymers produced in solution process
Inventor: WANG QINYAN
IPC: C08F210/16
Filed: 2020-09-28
Abstract: The copolymerization of ethylene with an optional comonomer is conducted in the presence of a catalyst having a specific aryloxy ether ligand structure. The process enables very high conversions of ethylene to polyethylene at very short residence times when conducted under conditions of pressures of at least 10.3 MPa and high ethylene feed concentrations of from 70 to 150 grams per liter. Using these polymerization conditions, the level of unsaturation may be controlled by the polymerization temperature: for example, a level of 0.09 vinyl groups per 1000 carbon atoms was observed at a polymerization temperature of 160°C and a level of 0.22 vinyls per 1000 carbon atoms was observed at 220°C.
