Abstract: An electronic device may have a housing in which an antenna is mounted. An antenna window may be mounted in the housing to allow radio-frequency signals to be transmitted from the antenna and to allow the antenna to receive radio-frequency signals. Near-field radiation limits may be satisfied by reducing transmit power when an external object is detected in the vicinity of the dielectric antenna window and the antenna. A capacitive proximity sensor may be used in detecting external objects in the vicinity of the antenna. The proximity sensor may have conductive layers separated by a dielectric. A capacitance-to-digital converter may be coupled to the proximity sensor by inductors. The capacitive proximity sensor may be interposed between an antenna resonating element and the antenna window. The capacitive proximity sensor may serve as a parasitic antenna resonating element and may be coupled to the housing by a capacitor.

Abstract: An electronic device may include an optical image sensor and a pin hole array mask layer above the optical image sensor. The electronic device may also include a display layer above the pin hole array mask layer that includes spaced apart display pixels, and a transparent cover layer above the display layer defining a finger placement surface capable of receiving a finger adjacent thereto.

Abstract: Described herein are computer-implemented methods, computer-readable media, and computer systems for the establishment of data communications between devices based through the use of acoustic signals. A first device transmits an acoustic signal, which is received by one or more other devices. The first device and the receiving devices establish a new communications network (e.g., create a new Wi-Fi network and/or peer-to-peer wireless network), or form/establish a grouping within a pre-existing communications network to which the devices are all connected. The devices can then exchange data over the new communications network or within the grouping on the pre-existing network. Also described herein are techniques for a device to determine its distance and/or other positioning information relative to another device, using acoustic and/or RF signaling.
