20170163379 | WIRELESS COMMUNICATION DEVICE AND METHOD - SISO decoding of a reception signal having a scrambled symbol arrangement is realized using a process having reduced complexity. Coordinates are generated for a reference point obtained by scrambling and mapping a symbol number not a symbol reference point position. This reference point simulates transmission-side scrambling and is generated for each symbol number by a first mapping unit. Because the binary expression of a corresponding original signal number is retained, a bit likelihood calculation unit can easily calculate a bit likelihood based on the distance between the reference point and a reception signal. The calculated bit likelihood is then deinterleaved and subjected to SISO error-correcting decoding. The thus obtained bit likelihood is then reinterleaved and used to calculate a symbol probability. Soft symbols are generated through the multiplication of all the calculated symbol probabilities by corresponding reference points output by a second mapping unit similar to the first mapping unit. | 2017-06-08 |

The method includes: (1) obtaining a plurality of messages, including one or more target messages authored by a particular user account; (2) obtaining a determination as to whether the messages includes at least one priority message authored by the particular user account; and (3) in accordance with a determination that the messages includes at least one priority message authored by the particular user account, displaying a user interface including: (a) at least a subset of the one or more target messages; (b) the at least one priority message; and (c) feedback for the at least one priority message, the feedback indicating a popularity of the at least one priority message. | 2017-06-08 |
20170163468 | SYSTEMS AND METHODS FOR PERMISSION-BASED MESSAGE DISSEMINATION IN A COMMUNICATIONS SYSTEM - The various embodiments described herein include methods, devices, and systems for disseminating messages in a communications system. In one aspect, a method is performed at a server. The method includes: (1) receiving a priority message from a first user of a plurality of users of the communication system, the priority message directed toward one or more users of the plurality of users, including a second user; (2) determining whether the second user has interacted with one or more prior messages of the first user; and (3) in accordance with a determination that the second user has interacted with the one or more prior messages of the first user, sending the priority message to the second user. | 2017-06-08 |
20170163469 | ELECTRONIC MAIL MESSAGING SYSTEM - The present invention comprises a method and apparatus for receiving, modifying and transmitting electronic communications. In one or more embodiments, the invention comprises a method performed by a server computer system that receives communications addressed to e-mail addresses created by the server computer system for recipients from senders having existing e-mail addresses. The server system creates modified e-mail messages by removing the sender's existing e-mail address and inserting an e-mail address created by the server computer system for that sender, wherein the created e-mail address identifies a name of the sender. The server computer system then transmits the modified e-mail message to an existing e-mail address of the recipient. | 2017-06-08 |
20170163470 | METHOD AND DEVICE FOR MEASUREMENT BY DEVICE-TO-DEVICE TERMINAL IN WIRELESS COMMUNICATION SYSTEM - An embodiment of the present invention relates to a method for measuring a device-to-device (D2D) signal by a D2D terminal in a wireless communication system, the method comprising the steps of: receiving a D2D signal; and carrying out a measurement using a reference signal included in the D2D signal, wherein the terminal determines the result of the measurement to be valid, when the measurement has been carried out within a measurement window, a value related to the intensity of the reference signal is higher than a preconfigured value, and the D2D signal has been successfully decoded. | 2017-06-08 |
20170163471 | Collaborative Recovery for an Account Associated with a Social Network - A system and method for recovering a user account is disclosed. A challenge module generates questions for recovering an account of a first user. The first user is associated with a social network. A verification module determines that the first user owns the account based on answers of the questions from the first user. A helper module determines a list of users that the first user can ask for help. The first user is connected to the list of users in the social network. The help module notifies the list of users about a recovery request submitted by the first user and receives responses from at least some users in the list of users. The verification module determines that the first user owns the account based on the responses. A recovery module recovers the account for the first user. | 2017-06-08 |
20170163472 | SYSTEMS AND METHODS OF ALERT GENERATION - Systems and methods for providing an alert to a user device based on generated parameters are disclosed herein. The system can include: a content management server; and a memory communicatingly connected to the content management server via a communication network. The memory can include: a content library database; and a user profile database. The system can include a user device and a supervisor device. The system can include a content management server that can calculate a risk probability and can generate and send an alert to the supervisor device when the risk probability exceeds a threshold level. | 2017-06-08 |
