TRANSFER OF EXERCISE DATA FROM AN EXERCISE DEVICE (18124500)

Inventor Henrik BENGTSSON

Brief explanation

This abstract describes a monitoring system for an exercise device that tracks a user's exercise activity. The system establishes a connection to a user device and broadcasts progress data during the connection process. Once the connection is established, it transmits data items representing the exercise activity. The user device receives the progress data and displays the progress of the exercise activity during the connection process. After the connection is established, the user device displays the progress based on the data received. This system allows the user to start their exercise activity without having to wait for the connection to be fully established.

Abstract

A monitoring arrangement for an exercise device generates data items representing exercise activity by a user, performs a connection process for establishment of an end-to-end connection to a user device, broadcasts progress data that represents data items generated during the connection process, and sequentially transmits, on the end-to-end connection data items, generated after establishment of the end-to-end connection. The user device receives the progress data and presents, during the connection process, progress of the exercise activity based on the progress data. After establishment of the end-to-end connection, the user device presents progress of the exercise activity based on data items received on the end-to-end connection. The combination of broadcasting and sequential transmission obviates the need for the user to wait for the end-to-end connection before starting exercise activity.

Brief explanation

The abstract describes an illumination apparatus that consists of three main components: a light source section, a phase modulation section, and a control section. The light source section includes a light emitting element. The phase modulation section is responsible for modifying the phase of the incoming light from the light source section. The control section manages the phase modulation section in a way that multiple domains, created by dividing the phase modulation plane, reproduce a light intensity distribution based on a common phase distribution. This common phase distribution is determined using a method called Freeform, and it is applied to a specific region on a projection plane.

The light source section has a light emitting element. The phase modulation section performs spatial light phase modulation on incident light from the light source section. The control section controls the phase modulation section in such a manner that a plurality of domains formed by dividing a phase modulation plane of the phase modulation section reproduces a light intensity distribution based on a common phase distribution determined on the basis of a Freeform method in a common region on a projection plane.

Inventor RAKSHA JALAN

Brief explanation

The abstract describes an electronic device that generates recommendations using trust-based embeddings. It collects correlation information about users in different domains and uses a Graph Attention Network model to create trust embeddings. These embeddings are then used in a recommendation model to suggest items to the user.

Abstract

An electronic device for generation of recommendations using trust-based embeddings is provided. The electronic device determines first correlation information of a first set of users associated with a first domain. The electronic device generates, based on the first correlation information, a first vector indicating a trust embedding of a first user with respect to the first set of users, in the first domain. The electronic device receives second correlation information associated with a second set of users associated with a second domain. The electronic device utilizes a Graph Attention Network model for the second correlation information to generate a second vector indicative of a trust embedding of the first user, with respect to the second set of users, in the second domain. The electronic device applies a recommendation model on the first vector and the second vector to recommend one or more items to the first user.

TRANSMIT IDENTIFIER TO USER PRIORITY / AC MAPPING (18179041)

Inventor Liangxiao Xin

Brief explanation

The abstract describes a method called Enhanced TID-to-UP mapping, which allows multiple Traffic Identifiers (TIDs) to be mapped to User Priorities (UPs) in a wireless network. This means that different types of data packets can be differentiated and prioritized for transmission. 

The method allows one device to set the TID-to-UP mapping for another device, enabling the classification and prioritization of different types of data packets. It also allows for the assignment of TIDs and UPs to specific traffic streams, which can further enhance the performance and reduce latency in the network.

Overall, this enhanced mechanism improves the efficiency and performance of data transmission in wireless networks by allowing for better differentiation and prioritization of different types of data packets.

Abstract

Enhanced TID-to-UP mapping is performed which allows multiple TIDs to be mapped to the UPs of the same AC. Thus, a first STA can set TID-to-UP mapping for a second STA, whereby TID-to-UP mapping can differentiate the MSDUs or A-MSDUs that are transmitted. In addition, an MSDU / A-MSDU can be classified by TID first, then use TID-to-UP mapping to map it to the corresponding UP. In addition, an SCS traffic stream can assign a TID and a UP to that SCS traffic stream. The use of these enhanced mechanism can enhance low latency performance.
