Abstract: A method of reducing gray energy consumption and achieving optimal gray energy saving for carbon neutralization is proposed. In a cellular network, each cell or BS (group of cells) has renewable (green) and non-renewable (gray, on-grid power) energy sources. The renewable (green) energy is highly variable and unpredictable, while non-renewable (gray, on-grid power) is stable but is not renewable and thus has more carbon impact. Each cell or BS (group of cells) services is associated UEs when it is on. In one novel aspect, a cell or BS (group of cells) that consumes more non-renewable energy can give some or all of its served UEs to another cell or BS (group of cells) that consumes less non-renewable energy.

Abstract: A system for generating and verifying a matrix barcode includes a generating device for generating a matrix barcode by encoding a target data set and a verification data set, and a verifying device. The matrix barcode has a verification zone presenting verification information that is related to the verification data set. The verifying device decodes the matrix barcode to obtain the target data set and the verification data set, obtains the verification information from the verification zone in the matrix barcode, and determines whether the verification information obtained from the verification zone is related to the verification data set obtained by decoding the matrix barcode.

Abstract: In a method for identity authentication, a portable electronic device displays a barcode encoding verification information for verifying authorization of access to the portable electronic device, and identification information for authenticating an identity of a user of the portable electronic device. An identification device scans the barcode and generates an authentication command. An authentication server extracts the verification information and identification information from the authentication command. When determined that the verification information is authentic, the authentication server authenticates the identification information and transmits a result to the identification device.

The control module allows establishment of a data connection to the electronic device after it is determined that credential information obtained from the electronic device is authenticated, receives an asserted user ID and an asserted user password from the electronic device, looks up a user authority in a permissions table based on the asserted user ID, and enables the electronic device to operate the storage module based on the user authority, the asserted user ID, the asserted user password and a ID-password table.

Abstract: A method is for managing an electronic medical record (EMR) entry which is to be written into a data storage device possessed by a patient and includes generating information associated with a health professional who provides a health care service that results in the EMR entry, and a location which is related to the health care service, determining whether to permit writing of the EMR entry into the data storage device according to the information thus generated, determining whether the patient agrees with writing of the EMR entry into the data storage device according to input of the patient, and writing the EMR entry into the data storage device when writing of the EMR entry is permitted by the EMR management system and is agreed upon by the patient.

Abstract: A mobile device includes an access control unit including a storage module and a control module, a memory unit storing an application program, and a processing unit connected to the aforementioned components. The processing unit executes the application program so as to transmit credential information to the access control unit for verification. When the application program is verified as authentic, the control module allows the processing unit to transmit an asserted user ID and an asserted user password thereto, looks up in a permissions table a user authority based on the asserted user ID, and enables the processing unit to operate the storage module based on the user authority, the asserted user ID, the asserted user password and an ID-password table.

Abstract: In a method for processing a payment, a seller-end electronic device transmits payment information to a transaction platform, which transmits an authentication code to the seller-end electronic device. A buyer-end electronic device allows the user thereof to input a verification code associated with the authentication code, and to transmit the verification code to the transaction platform. When the verification code is deemed valid, the buyer-end electronic device receives a personal identification number (PIN), and transmits a confirm signal to the transaction platform when the PIN is correct. The transaction platform then communicates with a bank terminal to process a payment, according to the payment information.
