A transmitter coil inductively couples to a receiver coil contained in a contact lens. In one approach, the transmitter coil is contained in a headgear, for example a head band. When the user wears the headgear, the transmitter coil is positioned on a side of the user's head and between the user's ear and the user's eye opening. In one implementation, a head band loops from one ear behind the user's head to the other ear, and also extends slightly forward of each ear. The transmitter coil(s) may be located in the portion of the headband that extends forward of each ear. This places the transmitter coil close to the receiver coil, typically within 40-50 mm of the user's eye opening, while still maintaining an unobtrusive aesthetic.

Headgear providing inductive coupling to a contact lens

An augmented reality system includes an electronic contact lens and a plurality of conductive coils to be worn, for instance, around a neck, around an arm, or on a chest of a user. The conductive coils can inductively couple to the electronic contact lens by producing magnetic fields that the electronic contact lens can convert into power. A direction of the resulting magnetic at the electronic contact lens can rotate over time, enabling the electronic contact lens to periodically form a strong inductive coupling with the plurality of conductive coils despite the orientation of the electronic contact lens. The electronic contact lens can also output a feedback signal representative of the power produced at the electronic contact lens or an orientation signal representative of the orientation of the eye, and the magnetic fields produced by the conductive coils can be altered based on the feedback signal or orientation signal.

An augmented reality system including a necklace and a contact lens display can be used to project information from the contact lens display onto the retina of the wearer's eye. In one example, the necklace generates a time-varying magnetic field (TVMF) that provides energy and information to the contact lens display via inductive coupling. The necklace can be configured to decrease the amount of energy absorbed by the body of the wearer and increase power transfer to the contact lens display. The necklace includes a conductive loop and one or more bucking loops that are positioned to increase transmitted energy while reducing the amount of energy absorbed by the human body. The amount of current travelling in one direction through the loops of the necklace is greater than the amount of current travelling in the opposite direction through the loops of the necklace. The necklace can include any number of signal generators and winding patterns for the loops.

Power generation necklaces with field shaping systems

An augmented reality system including a source and a contact lens display can be used to project information from the contact lens display onto the retina of the wearer's eye. The source provides energy to the contact lens display and operates at a source frequency. The source includes a source circuit including a conductive coil. The contact lens display includes a resonant circuit including another conductive coil and a capacitive circuit. The resonant circuit receives energy from the conductive coil of the source via a magnetic field inductively coupling the conductive coils. The contact lens display additionally includes a feedback circuit to adjust the capacitance of the capacitive circuit to control a resonant frequency of the resonant circuit. The feedback circuit can control the capacitive circuit to maintain the resonant frequency of the resonant circuit near the source frequency as the wearer's eye blinks.

Adaptive tuning of a contact lens

An augmented reality system can include an electronic contact lens, a power source, and a head wearable object. The contact lens, power source, and head wearable object all include corresponding conductive loops to enable wireless transfer of power between the power source and the contact lens. When current is driven through a conductive loop of the power source, the power source generates a primary time-varying magnetic field. The primary time varying magnetic field induces a current in a conductive loop of the head wearable object. The induced current in the head wearable object generates a secondary time-varying magnetic field. Both the primary and secondary time varying magnetic field generate a current in the conductive loop of the contact lens. The system can also include a haptic feedback system that allows information to be communicated between elements of the system.

An augmented reality system including a necklace and a contact lens display can be used to project information from the contact lens display onto the retina of the wearer's eye. In one example, the necklace generates a time-varying magnetic field (TVMF) that provides energy and information to the contact lens display via inductive coupling. The necklace can be configured to minimize the amount of energy absorbed by the body of the wearer while maintaining power transfer to the contact lens display. In one example, the necklace includes multiple conductive coils generating constructively interfering TVMs to effectively transmit energy while reducing the amount of energy absorbed by the human body. In another example, the necklace includes a parasitic coil generating a destructively interfering TVMF and a magnetic shield to effectively transmit energy while reducing the amount of energy absorbed by the human body.

Embodiments of the present application relate generally to electronic hardware, computer software, wireless communications, network communications, wearable, hand held, and portable computing devices for facilitating communication of information and presentation of media. An electrically conductive substrate, such as a sheet of metal or metal alloy, for example, includes an active antenna formed by a slot or opening formed in the substrate, and also includes at least one separate passive slot or opening (e.g., a passive slit) formed in the substrate. The active antenna may be intentionally detuned from one or more target frequencies (e.g., 802.11, 2.4 GHz, 5 GHz) such that the active antenna is not optimized (e.g., is not tuned) for the one or more target frequencies. One portion of the active antenna may be electrically coupled with a ground potential. Another portion of the active antenna may be electrically coupled with a RF receiver, transmitter, or transceiver.

A re-configurable RF architecture includes both a 2&#xd7;2 MIMO mode and a 1&#xd7;2 MIMO mode The 2&#xd7;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&#xd7;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&#xd7;2 MIMO mode to the 1&#xd7;2 MIMO mode when near field proximity detection is required. In the 1&#xd7;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.

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.

Methods, systems and apparatus to affect RF transmission from a non-linked wireless client

An apparatus, method, and computer program product are described that provide for a user to share content with other users who are proximate to his or her device in a simple and intuitive manner. In some embodiments, a 'wave' gesture is used to identify users of devices that nearby to the source user's device with whom the source user may communicate, such as to share content. Upon receiving a first orientation input, a scanning mode may be initiated during which one or more devices proximate the apparatus are determined. A second orientation input that is different from the first orientation input, and the scanning mode may be terminated in response. As a result, a communication with at least one selected device of the one or more devices determined to be proximate the apparatus may be facilitated.
