A capacitive sensing identification tag includes a substrate and a touch sensing layer disposed on one side of the substrate. The touch sensing layer includes high-sensing regions and low-sensing regions with different shapes. Both the high-sensing regions and the low-sensing regions have different stacked conductive layers and dielectric layers. A difference between the high-sensing regions and the low-sensing regions is that each of the high-sensing regions contains a dielectric layer, while each of the low-sensing regions does not. The capacitive sensing identification tag achieves an effect of sampling and identification of a touch panel by a capacitive sensing quantity that is different from a capacitive touch panel. And the capacitive sensing identification tag will not cause a difference in color or light transmittance between the high-sensing regions and the low-sensing regions, so there is no visible difference between the high-sensing regions and the low-sensing regions.

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.

A method for configuring a mobile terminal to control vehicle functions of a vehicle, where the mobile terminal and the vehicle each have a short-range radio system, includes receiving a request to a server to issue a vehicle key for the use of vehicle functions of the vehicle for a mobile terminal. The method also includes generating the vehicle key by the server, transmitting the vehicle key to a secure element of the mobile terminal, and storing the vehicle key in the secure element of the mobile terminal.

An apparatus for preventing malfunctions of a touchpad disposed near an antenna is provided. An NFC coil is disposed underneath a touchpad. In NFC, an NFC card approaches the surface of the touchpad. A touch controller sets the detection sensitivity of a finger to a reference value when an NFC module does not emit alternating magnetic fluxes. The touch controller reduces the detection sensitivity at the timing when the NFC coil starts the emission of the alternating magnetic fluxes. The touch controller returns the detection sensitivity to the reference value at the timing when the NFC coil stops the emission of the alternating magnetic fluxes. The NFC module directly transmits a signal with which the touch controller changes the detection sensitivity to the touch controller through a hardware line.
