摘要:
Techniques for mobile device speaker control are described, including monitoring one or more devices coupled to a data network, receiving one or more data packets from each of the one or more devices, filtering the one or more data packets by evaluating a received signal strength of each of the one or more packets, the one or more packets being ordered in a priority based on a value, and comparing the received signal strength of each of the one or more packets to a threshold to determine whether the one or more devices are to perform an action.

Interaction between wireless devices, one of which may be equipped with a directional radio (a radio with a directional antenna for directional sensing capabilities) can be used in directional peer-to-peer networking. A method can include obtaining, at a first device from a serving device, proximity information regarding a second device. The method can also include obtaining, at the first device from the serving device, direction information regarding the second device. The method can further include calculating a position of the second device with respect to the first device based on the proximity information and based on the direction information. The method can additionally include communicating with the second device based on the position.

Embodiments of the present application relate generally to wireless electronics, wireless portable electronics, wireless media presentation devices, audio/video systems, and more specifically to passive or active RF proximity detection of wireless client devices in an environment that may or may not include wireless access points. A wireless client device may be forced, triggered, or configured to broadcast a wireless scan (e.g., an active WiFi scan) that includes data (e.g., packets) that may be discovered by a wireless media device (e.g., received by RF circuitry in the media device) and information from the wireless scan may be used by the wireless media device to detect presence of the wireless client device and/or its user, to establish a wireless data communications link with the wireless client device, to determine proximity of the wireless client device to the wireless media device, and for near field communication (NFC) with the wireless client device.

This invention describes a method for improving antenna isolation in an electronic communication device using grounded RF microwave elements and patterns (structures). According to embodiments of the present invention, the RF microwave element can be implemented as a short-circuited section of a quarter-wavelength long transmission line (such as a stripline), or the RF microwave element can contain a metallic coupler and two thin striplines with different lengths, or the RF microwave element can be implemented using a balun concept.

A re-configurable RF architecture includes both a 2×2 MIMO mode and a 1×2 MIMO mode. The 2×2 MIMO mode includes a first RF chain coupled with a first dual band antenna and configured to both transmit (Tx) and receive (Rx) using two different RF protocols. The 2×2 MIMO mode also includes a second RF chain coupled with a second dual band antenna and configured to both Tx and Rx using a single RF protocol. The first RF chain may be coupled with a third antenna configured for near field proximity sensing. The RF architecture is reversibly switchable from the 2×2 MIMO mode to the 1×2 MIMO mode when near field proximity detection is required. In the 1×2 MIMO mode the Tx/Rx capabilities of the second chain using the second dual band antenna are retained and the first chain is configured for Rx only capability using the third antenna.

Methods, apparatuses and computer program products are provided for facilitating interaction via motion gestures. A method may include receiving an indication of at least one motion gesture made with a device. The method may further include determining a contextual state of a device. The method may additionally include determining, by a processor, a relationship between the at least one motion gesture and each of a plurality of predefined motion gestures and causing, based at least in part on the determined relationship, the device to perform an action associated with a respective predefined gesture. Corresponding apparatuses and computer program products are also provided.

The specification and drawings present a new apparatus, method and software product for using a cover antenna (e.g., conductive, metallic, etc.) in an electronic device, with multiple coupled feeds (e.g., dual feed) to the antenna and with one or more switches and a matching circuit. Then it is possible to use a metal plate as a metal cover, e.g., for mobile devices, which will act as an antenna with multiple feedings for cellular and non-cellular radios.

摘要:
Embodiments relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, electronic media presentation of audio and video, and wearable/mobile computing devices configured to facilitate communication among electronic devices, including mobile phones and media devices that present audio and/or video content. More specifically, disclosed are systems, components and methods to autonomously discover and/control operation of devices, such as media devices, by modulating and demodulating packet characteristics to establish an overlay communication channel. In various embodiments, a method includes receiving at least one RF channel including an overlay communication channel over which packets convey message data modulated with characteristics of the packets. The method includes selecting the RF channel and demodulating a subset of the packet characteristic values to form extracted symbols. At least one method can select a device that autonomously discovers another device using modulated packet characteristics.

Mobile device speaker control may include: monitoring one or more devices wirelessly coupled with a data network, receiving one or more data packets from each of the one or more devices, filtering received data packets by evaluating a received signal strength (e.g., RSSI) of the received packets, comparing the received signal strength of each of the received packets to a threshold to determine whether the one or more devices are to perform an action, and performing the action only if one or more indicia other than the received signal strength indicate a near field proximity within the threshold or a direct physical contact between a wireless device receiving the data packets and one of the one or more devices that is wirelessly transmitting the data packets.
