Disclosed is a ring shaped wearable communication device (ring) for a user's finger. The ring includes: a sound sensor that detects ambient sound levels; a speaker that produces sound in human audible frequency range per at least one signal received, wherein intensity of the sound produced is based on the ambient sound level; an out port; and a hollow channel with an increasing cross-section that wraps around the finger, wherein: smaller cross-section end of the hollow channel is connected to the speaker and the other end of the hollow channel is connected to the out port to provide a horn-like structure; the out port and the hollow channel are configured to reduce the mismatch between the acoustic impedance of air immediately outside the out port and the acoustic impedance as seen by the speaker just outside the speaker; and the out port emits sound received from the speaker as directional sound in close vicinity of the user's hand.

Systems and methods are presented for establishing a communication link between two or more electronic devices. A portable eyewear electronic device is configured to communicate with a handheld electronic device, such as a ring, that in turn is retained by an accessory electronic device to establish a wired communication link. The accessory electronic device may be retained or housed by a second accessory electronic device, such as a remote control or wearable device.

Provided is a wearable personal digital device for point of healthcare saliva testing. The wearable personal digital device may comprise a processor, a display, biometric sensors, activity tracking sensors, a memory unit, a communication circuit, a housing, an input unit, a projector, a timepiece unit, a haptic touch control actuator, a band, a mounting clip, a saliva sample insert apparatus, a pinhole, a light emitting diode board, a battery, and a set of sensors. The processor may be operable to receive data from an external device, provide a notification to a user based on the data, receive a user input, and perform a command selected based on the user input. The housing may be adapted to enclose the components of the wearable personal digital device. The band may be adapted to attach to the housing and secure the wearable personal digital device on a user body.

An improved wearable locator has an ultra-low power RF transceiver, GPS receiver, cellular network RF transceiver, processor, programmable non-volatile memory, LCD display, accelerometer and rechargeable battery. To ensure that the locator is within a perimeter, it can cooperate with a subordinate unit that includes an ultra-low power RF transceiver, processor, power supply, DC charging output, rechargeable battery, visual, audible and tactile enunciators and pushbutton, and can be plugged into an outlet or be unplugged and be mobile. Other wireless units can be used to define a perimeter.

The present disclosure relates to a wearable radio device for access control. The radio device has an inside portion and an outside portion. The inside portion includes a first transponder and a second transponder. A first barrier is located between the first transponder and the second transponder. A second barrier is located between the first transponder and the second transponder in an outside portion of the wearable device.

Systems, devices, and methods that are effected in or by an electronic device in response to establishing and/or terminating a physical communications link are described. An electronic device may be entered into deep sleep and may include a power control circuit that activates the device out of deep sleep in response to establishing a physical communications link with a source of electric power, such as another electronic device. Either in combination with or separate from this, an electronic device may establish wireless communications with another electronic device in response to establishing and terminating a physical communications link with the other electronic device. The physical communications link may be used to transfer device identity data from one device to the other and thereby bypass the cumbersome “discovery” process common to conventional wireless communication techniques. Portable electronic devices and personal computing devices that are operative to perform the above are described.

Cases, devices, and methods for protecting and holding portable handheld devices, such as cell phones and smart phones, in separate protective cases having outwardly extending resilient bumper corner eye lit rings which cushion the case and function as bumpers when the portable electronics device are dropped. The outwardly extending bumpers/eye lit rings can also support lanyards and keychain rings, and the like, so that the cases with portable electronics devices can be easily and safely held in one's finger, about their wrist, or on their neck. A central ring can be formed from an upper middle portion of the case for allowing the forefinger of a user to be inserted therein with the back of the hand supporting the case, and the lanyard wrapped about the user's wrist. The novel cases can also be used to safely protect other types of portable electronic devices, such as tablets and laptop computers, and the like, in similar manners. Portable electronic device housings can be initially manufactured and built with the outwardly extending resilient rings offering safe protection from being dropped and for being held, carried or worn.

An exemplary wearable mobile device attachment article comprises a mobile device cover with a first face and a second face opposite the first face. An exemplary first face may be configured to provide access to the screen of a mobile device. A receptacle may project outwardly from the second face while a wearable article has at least one surface for frictionally engaging the mobile device cover.

A wearable device can establish a verified session with a host device. For example, if a user wearing the wearable device unlocks the host device (e.g., by entering a credential), the devices can create a verified session, which can persist across lock and unlock events at the host device. For the duration of the verified session, a host device can request session confirmation from the wearable device at any time to confirm that the verified session is still in progress. While the session is in progress, the host can make features available such as bypassing re-entry of a credential during unlock operations.

An apparatus that facilitates one-handed use of a mobile device has a finger brace coupled a plurality of flexible lengths. At least one of the flexible lengths is coupled to an intermediate point of the finger brace. Each of the flexible lengths is coupled to the mobile device at its rear-facing back. At least two of the flexible lengths are coupled at opposed ends of the rear-facing back. The length of the flexible lengths and where they are coupled to the brace and mobile device are such that two fingers of the user's hand can press against the finger brace on opposed sides of the intermediate point to brace the mobile device when the two fingers are between the finger brace and the mobile device.
