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.

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.

An improved case for electronic devices including a detachable and rotatable hand strap. The improved case is structured and arranged to secure electronic devices therein and to the hand of a user. The detachable and rotatable hand strap offers a full 360° of rotation and thus a more comfortable and reliable grasp to thereby reduce the risk of dropping and damaging the electronic devices.

A communication interference rejection system comprising a receiver operatively connected to a device connected to a body of a user. The receiver is configured to receive a signal transmitted through the body of the user, the signal comprising a data component and an interference component, the interference component due to human body antenna effect. The receiver is configured to integrate the signal using a relatively low-gain analog integrator and then digitally differentiate the output of said integration.

A magnetically configurable strap accessory for a mobile communications device and method of using the same is disclosed. The magnetically configurable strap accessory includes a strap and a base. The strap includes at least one strap magnet. The base includes at least one base magnet and a sleeve disposed at a first end of the base into which a portion of the strap can be retracted when the accessory is in a closed position and from which a portion of the strap can be extended when the accessory is in an open position. In the closed position, the strap is held in a substantially flat position against the base by way of magnetic attraction between at least one of the strap magnets and at least one of the first base magnets. In an open position, the strap is held in a substantially arched position with respect to the base hereby forming a loop between the base and the strap.

A wearable device can establish a verified session with a host device (e.g., by establishing that the wearable device is present in the vicinity of the host device and is currently being worn). The existence of such a verified session can be used to control user access to sensitive information that may be stored in or otherwise accessible to a host device. For example, the host device and/or application programs executing thereon can be configured to restrict a user's ability to invoke program functionality that accesses sensitive information based on whether a verified session with a wearable device is currently in progress.

A flexible handle assembly for holding a portable electronic device includes a ring-shaped ferromagnetic base mount (2212) with a ring-shaped magnet base (2220) with at least one arcuate portion (2222, 2224, 2236, 2238) with a set of two or more base magnets (2226, 2228) disposed therein, for magnetically coupling with a portion (2214 or 2216) of the ring-shaped ferromagnetic base mount (2212). The assembly also includes a flexible strap assembly (2240) with a first arcuate end (2242, 2250) with a first set of two or more magnets disposed (2242) therein for magnetically coupling with a portion (2230) of the ring-shaped magnetic base (2220) and a second arcuate end (2244, 2252) with a second set of two or more magnets (2248) disposed therein, for magnetically coupling with another portion (2232) of the ring-shaped magnetic base (2220), and a flexible strap (2264) with a first end (2260) fastened to the first arcuate end (2242, 2250) and a second end (2262) fastened to the second arcuate end (2244, 2252).

Method for controlling a wearable user device, which is a sensor and/or information device including establishment of a wireless communication link between the user device and a gateway, transmission of a connection event message to the process control system, wherein the connection event message contains an identifier of the user device, an identifier of the gateway and information on the successful establishment of the communication link, transmission of sensor data from the user device to the process control system, generation of at least one control instruction by the process control system in response to the received sensor data, wherein the control instruction is generated depending on the identifier of the gateway and depending on the received sensor data, and transmission of the at least one control instruction to the user device. Furthermore, a wearable user device as well as a control system are disclosed.

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.

A system in accordance with present embodiments includes a plurality of wearable devices and a virtual queue control system configured to maintain respective virtual queues for respective attractions and in communication with the plurality of virtual queuing attraction stations. The virtual queue control system is configured to receive communications from the plurality of virtual queuing stations and add guests to the respective virtual queues based on the communications.
