The present disclosure provides a range-finding system capable of data communication. The range-finding system includes a rangefinder for acquiring ranging data, a magnetic ring unit having at least two communication channels, and a data processing and control unit. Each communication channel includes a magnetic ring. The magnetic ring unit transmits the ranging data as downlink data from the rangefinder to the data processing and control unit via one or more of the communication channels.

A power saving wire-free earpiece has a Bluetooth transceiver and a Bluetooth Low Energy (BLE) transceiver. A stream of audio from a remote source is separated into a local audio stream and a stream sent to the BLE transceiver for a remote earpiece. The earpiece is operative in a first and second mode, the first mode enabling the BT transceiver and BLE transceiver, the second mode enabling only the BLE transceiver for receiving remote streams of data. The first and second mode alternate so that the local and remote earpiece have substantially uniform current requirements.

A wireless device system employs short-range wireless communication to require the proximity of a user device to a defined area prior to communicating a request or notification to the wireless user device. The system authenticates a request and the proximity of the user to or within the defined area prior to transmitting a command, request, or notification to the user or a third party. Additionally, the system uses an access node configured to shape the radiation pattern of short-range wireless communications to better determine the position of a user proximate in or around a defined area.

Disclosed embodiments provide techniques for managing custom media overlays for social media applications. Custom media overlays, sometimes referred to as filters, lenses, or effects, can be used to augment a digital image, providing entertainment and increasing engagement in social media applications. In various situations, it may be desirable to reveal a custom media overlay only after an associated event has occurred. Disclosed embodiments allow a custom media overlay to be defined and associated with an event. Prior to the event occurrence, the custom media overlay is only available to a first subset of users. Once the event occurs, the custom media overlay is provided to a second subset of users. In this way, the custom media overlay is concealed from the second subset of users until the event occurs.

Control over the operation of an electrically-controlled motor is supported by an interface circuit between the electrically-controlled motor and a near-field radio frequency communication controller. The interface circuit includes a first circuit that receives at least one control set point through a near-field radio frequency communication issued by the near-field radio frequency communication controller. A second circuit of the interface generates one or more electric signals in pulse width modulation based on the control set point.

A packaging system for at least one article includes a multilayer laminate structure and at least one sensor. The laminate structure encapsulates a transformative material between first and second conductive layers, which undergoes a state change that changes impedance between the first and second conductive layers in response to a perforation produced by the at least one sensor. An NFC/RFID circuit is electrically coupled to the first and second conductive layers of the multilayer laminate structure. At least one operational characteristic of the NFC/RFID circuit is dependent on the impedance change between the first and second conductive layers in response to a perforation produced by the sensor under predetermined environmental conditions. The operational characteristic(s) of the NFC/RFID circuit can be ascertained and analyzed (for example, by operations of an NFC/RFID interrogator) to detect and register the predetermined environmental conditions and provide an indication thereof.

Example embodiments of systems, methods, and devices for transaction card alignment are provided. In one example embodiment, a mobile device may include a first component and a second component foldable with respect to one another between a first configuration and a second configuration. The mobile device may further include a screen interface on an interior side of the first component, and an alignment feature along the interior side, the alignment feature providing alignment for a contactless card with respect to the screen interface, wherein the contactless card is uncovered by the second component in the first configuration and covered by the second component in the second configuration.

A wireless communication apparatus which comprises: a shared antenna shared for communication and power reception; an impedance matching circuit connected to the shared antenna and having a first switch element; a communication circuit connected to the impedance matching circuit; a second switch element connected to the first switch element; and an impedance matching adjustment circuit configured to switch an on/off state of each of the first switch element and the second switch element at the time of communication and at the time of power reception.

Embodiments of this specification provide a method and apparatus for quick enabling a service in an application program and an electronic device. When a user terminal receives tag content transmitted by a near field communication (NFC) tag, an operating system of the user terminal may enable an application program that has registered NFC. Then, the enabled application program uploads the tag content to a server. According to a service routed by the server after the server decodes the tag content, the application program executes the routed service.
