A phone grip attachment includes a base configured for attachment to a phone and a finger-hold attached to the base. The finger-hold has a top member and a bottom member. The finger-hold is movable between an extended position in which an opening is defined between the top member and the bottom member for use in gripping the phone and a collapsed position in which the top member is substantially flat against the bottom member. The finger-hold can be biased to the extended position. The finger-hold can be rotatably attached to the base.

A wireless device can store account identifiers and facilitate transactions. The wireless device can be loaded with user account identifiers and can be presented to various checkpoint devices. When presented, the wireless device can transmit a selected account identifier to the checkpoint device. In the context of a purchase transaction, the checkpoint device can be a point-of-sale terminal and the account data can be financial account data. In some instances, the wireless device can also facilitate a purchase transaction, e.g., by obtaining information about products to be purchased, constructing a purchase order from the product information, and transmitting the purchase order to a point-of-sale terminal.

Systems and methods for managing communications between a wearable computing device and at least one remote computing device, using a host computing device. The host computing device provides a message handling service that receives one or more messages directed to the wearable computing device from the remote computing device, or directed to the remote computing device from the wearable computing device, and, for each of the one or more messages, determines an action associated with the respective message; and takes the action for each of the one or more messages.

A method includes providing a main frame configured to be attached to a surface associated with a portable electronic device, and providing a grip element. The method also includes forming a grip device based on receiving one or more slide element(s) of the grip element through a channel of the main frame, and enabling portrait and landscape orientation based operations associated with the portable electronic device through the attachment of the formed grip device to the portable electronic device.

A wearable device is described. The wearable device includes a body portion and an adjustable strap affixed to a body portion to form an opening. The opening receives a body part of a user therein. The wearable device includes a control component, a gesture component, and/or a sensing component configured to detect input, gestures, and/or biometric parameters of the user and transmit the input, the gestures, and/or the biometric parameters to a smart device connected to the wearable device via a wireless personal area network technology to modify parameters of the smart device. The wearable device may include one or more sensors that assist the control component, the gesture component, and/or the sensing component.

The present disclosure provides a method of generating codebook in a wireless communication system with multiple antenna arrays, as well as a wireless communication system, base station and terminal using the codebook for communication. The method comprises steps of: providing a basic codebook which contains multiple pre-coding matrices; and assigning phase offsets to certain pre-coding matrices in the basic codebook to form a codebook with phase offset. The feedback overhead from a client to a base station side is reduced and a good precision of feedback for multi-antenna array is kept by applying the method of generating codebook and using the generated codebook in the wireless communication system, base station and terminal.

A device for monitoring a health parameter in a person is disclosed. The device includes a semiconductor substrate, at least one transmit antenna configured to transmit millimeter range radio waves over a 3D space below the skin surface of a person, multiple receive antennas configured to receive radio waves, the received radio waves including a reflected portion of the transmitted radio waves, wherein the semiconductor substrate includes circuits for processing signals received on the multiple receive antennas, wherein processing signals includes mixing signals of two different frequencies, and wherein the semiconductor substrate includes at least one output configured to output a signal that corresponds to a health parameter of a person in response to received radio waves.

Methods and systems for improving and/or enabling wireless communication and data transfer between electronic devices worn by swimmers and both wireless networks and wireless headphones or other worn devices. The methods and systems disclosed detect when conditions are sufficient for wireless communication depending on the position of a worn electronic device relative to the surface of the water and/or wireless headphones and enables burst data transfer between devices and/or between a device and a wireless network during such times.

Systems, devices, and methods for proportionally balancing power during wireless communication are provided. The disclosures provide for an integrated radio in which the functionality of an active radio and a passive radio are integrated into a single radio, with the active and passive radios each being configured to operate in three different modes: active, passive, and backscatter. Based on power and communication link information, the integrated rode is able to balance the modes at which the two radios are operated, thereby optimizing power consumption of the device into which the integrated radio is incorporated. The resulting systems, devices, and methods lead to ultra-low power consumption that enables these communication techniques to enhance computing devices from smartwatches to laptops. Devices incorporating the integrated radios, and methods for power-proportionally exchanging data, among other systems, devices, and methods, are also provided.

A stand for a mobile device. The stand includes a back plate having a pair of parallel tracks, the back surface of the back plate attached to a back surface of the mobile device. The stand includes a sliding plate having a first end coupled to the back plate and configured to slide along the pair of parallel tracks. The stand includes a pivot plate having a first end connected to the second end of the sliding plate at a hinge, a second end connected to the back plate, and the pivot plate is configured to pivot relative to the back plate when the first end of the sliding plate slides along the pair of parallel tracks. The pivot plate, the sliding plate, and the back plate form one or more channels for receiving one or more fingers of a user when the stand is in the deployed position.
