A method and system for receiving digital artifacts from a management server. The method includes sending a request for a digital artifact from a mobile application to the management server for display within a specific mobile application generated screen, receiving the digital artifact from the management server, and displaying the digital artifact with the specific mobile application generated screen.

A communication device includes a first processing unit that sends a first command to start an activation processing. The communication device also includes a second processing unit that receives the first command from the first processing unit. In addition, the communication device includes an interface between the first processing unit and the second processing unit. The first processing unit activates the interface at a predetermined interface level from among a plurality of interface levels. The second processing unit starts an application in accordance with the activated interface level. The first processing unit and the second processing unit exchange data by the activated application. The first processing unit and the second processing unit perform a deactivation processing of the activated interface.

According to an aspect, a display device includes: a display portion having a display region; a backlight configured to illuminate the display region from a back side of the display portion, the backlight including a light guide plate, and a light source provided facing a lateral side of the light guide plate and configured to emit light; an antenna electrode wound around, facing a back side of the backlight, and configured to reflect light within the display region in a plan view, the light having entered the light guide plate from the light source; and a plurality of dummy electrodes provided on a part of a plane on which the antenna electrode is provided, the part being in a region unoccupied by the antenna electrode. The dummy electrodes reflect light within the display region in a plan view, the light having entered the light guide plate from the light source.

A method for activating an electronic subassembly includes receiving at least one activation signal using a reception module of the electronic subassembly. The electronic subassembly is transferred from an idle state to an active state using the at least one activation signal. The electronic subassembly is intermittently supplied with electric power via the at least one activation signal.

An electronic device may include an antenna element, coil, sensor board, and grounding ring structures. The coil may receive wireless charging signals through the grounding ring structures. The grounding ring structures may include concentric ring-shaped traces separated by at least one gap. The ring-shaped traces and gaps may configure the grounding ring structures to short antenna currents at relatively high frequencies from the antenna element to a ground trace on the sensor board while blocking currents at relatively low frequencies. The grounding ring structures may include conductive wings that increase capacitive coupling between the grounding ring structures and the antenna element. The grounding ring structures may be soldered to the antenna element. The antenna element and the grounding ring structures may be formed from traces patterned on the same substrate. The ground trace may form part of an antenna without substantially impairing wireless charging efficiency of the coil.

A transaction card may monitor an amount of electric current induced in a first near-field communication (NFC) component of a transaction card. Electric current may be induced in the first NFC component when the first NFC component is within an electromagnetic field generated by a second NFC component of a transaction terminal. The transaction card may dynamically activate one or more output components associated with the transaction card based on the amount of electric current induced in the first NFC component. The one or more output components may indicate whether the transaction card can communicate with the transaction terminal. The transaction card may perform an action related to completing a transaction after determining that the amount of electric current induced in the NFC component satisfies a first threshold. The first threshold may indicate that the transaction card can communicate with the transaction terminal.

An emergency alarm system peripheral, such as a hazard detector, intrusion detector, or a notification appliance, includes a base that is permanently installed on a wall or ceiling, and a head which mounts to the base. Various embodiments and methods are provided to easily and efficiently assign addresses to the peripherals in the system.

One example discloses a near-field interface device, including: a near-field antenna; a physical port configured to be coupled to a computer; a controller coupled to the antenna and the physical port; wherein the controller is configured to translate a near-field signal received from the near-field antenna into an input command generated by a user; and wherein the controller is configured to transmit the input command to the computer through the physical port.

A sensor module for monitoring an asset in an electrical power generation or distribution system includes a module body, a sensor, a sensor near field coupling structure, and an interrogation near field coupling structure. The sensor is supported by the module body, arranged to sense a parameter of the asset and configured to generate a sensor output relating to the parameter. The sensor near field coupling structure is connected to the sensor and supported on a first side of a module body. The interrogation near field coupling structure is supported on a second side of the module body. The sensor output is transmitted from the sensor near field coupling structure to the interrogation near field coupling structure. The sensor module is configured to provide electrical isolation between the asset and a monitoring circuit configured to receive the sensor output through the interrogation near field coupling structure.
