Abstract: The described embodiments concern one or more methods, systems, apparatuses, and computer readable mediums storing processor-executable process steps to authenticate mobile subscribers for using a foreign application when they are outside of their home telecom carrier's mobile network zone (“foreign zone”). A mobile subscriber can be authenticated through data roaming service, voice roaming service, and/or WiFi service. After cross network authentication, a mobile subscriber can use the foreign application to provide the same or similar services in a foreign zone, such as foreign country, through the home services in connection with the subscriber's home telecom carrier in a similar manner like he/she can use in his/her home zone, such as home country.

Abstract: A lock for securing a portable device is disclosed. The lock can be inserted into a cavity. The cavity has a first sidewall and a second sidewall both of which extend away from an opening into the cavity with a gradually increasing distance between the two sidewalls for a section of the two sidewalls. The lock for securing a portable device comprises a lock body; a first engaging member projecting from the lock body and having an outside part outside the lock body, a cross-sectional area of the outside part of the first engaging member being substantially the same or become larger from a front end towards a rear end of the outside part of the first engaging member; and a second engaging member, connected to the lock body and configured to move along a side of or across the first engaging member to insert into the cavity for a locking status and to withdraw from the cavity for an unlocking status.

Abstract: A head wearable display system includes a head wearable device for a user and an image processing module, to process the images captured by a first image sensing module and a second image sensing module. The head wearable device includes a frame to be worn on the user's head, a display module, disposed on the frame. The first image sensing module to capture images in a first direction toward the user's face, and the second image sensing module to capture images in a second direction away from the user's face. In this device, the first image sensing module and the second image sensing module are adjustably mounted on the frame.

Abstract: The present disclosure concerns methods and systems for storing and selecting digital property pieces from and for a transaction, and for managing the changes from a transaction, based on cryptographic technology in a digital property management system, in order to improve the throughput and performance of the system. The digital property management system can define and maintain a plurality of bins for storing digital property pieces in memory. After receiving a transaction request at a transaction value, the digital property management system can determine a transaction bin, from which digital property pieces can be selected for a transaction.

Abstract: The present disclosure concerns methods and systems for increasing anonymity and traceability of a digital property management system that manages digital property transactions on a distributed transaction consensus network. The digital property management system comprises a sender's digital property manager and a recipient's digital property manager. The sender's digital property manager further comprises a sender's module and a sender's transaction node and the recipient's digital property manager further comprises a recipient' module and a recipient's transaction node. To increase anonymity of a remittance transaction between, sender's module is not allowed to access a recipient's virtual identification. Thus, recipient's module generates a token to temporarily replace a recipient's virtual identification. To increase anonymity, an encrypted label is generated for each sub-transaction to identify sub-transactions and their sequence in the same remittance set.
