摘要:
A circuit arrangement includes an antenna port, a transmission port, and a reception port, each of which is connected to one respective 90° hybrid that splits an input signal into two output signals that are in quadrature. The circuit arrangement also includes two duplexers which are connected in such a way that the two output signals emitted by the 90° hybrid that is connected to the transmission port constructively interfere on the antenna port, while spurious signals caused by the two output signals destructively interfere on the reception port.

A wireless signal communication system controls wireless signal transmission levels in response to detection of attenuation characteristics of a medium in a line of sight of the wireless signals. In one form, the system performs real time detection of moveable objects in a line of sight of sub-terahertz electromagnetic waves delivered to data streaming, charging, and other systems. The system downscales the signal transmission level responsive to the presence of the moveable object in the line of sight or based on an increase attenuation of the signal, and up-scales the signal transmission level responsive to the absence of the moveable object in the line of sight or based on a decrease in the attenuation of the signal.

Systems, apparatuses, and methods for secure beacon authentication via mobile devices are disclosed. In some example embodiments, a verification element comprises: a memory storing a plurality of non-repeated verification codes; a wireless broadcast element; and a processing circuit electronically coupled to the memory and the wireless broadcast element, the processing circuit being configured to retrieve one of the non-repeated verification codes from the memory and to transfer the non-repeated verification code to the wireless broadcast element, the wireless broadcast element being configured to wirelessly broadcast the non-repeated verification code to a plurality of mobile devices for individual verification of the plurality of mobile devices, the non-repeated verification code being different than any other non-repeated verification code previously retrieved from the memory and used for individual verification of the plurality of mobile devices.

A communication device includes a transmitter (TX), a receiver (RX), one or more adaptively-tunable Electrically-Small Antennas (ESAs), and a control unit. The transmitter is configured to produce a TX signal for transmission on a TX frequency band. The receiver is configured to process an RX signal received on an RX frequency band. The adaptively-tunable ESAs are configured to transmit the TX signal on the TX frequency band and to receive the RX signal on the RX frequency band. The control unit is configured to adaptively tune respective responses of the one or more ESAs in the TX or RX frequency band.

A Wearable Medical System includes a support structure that is configured to be worn by a person. The WMS also includes an electronics module, a cable assembly, and at least one electrode that can be configured to be coupled to the support structure. The cable assembly includes a base member and a cable coupled to the base member. The support structure can be dimensioned relative to the person's body to be worn with tension, and be resiliently stretched under the tension. The stretching of the support structure can stretch the base member of the cable assembly, thus increasing the effective length of the cable, while reducing or even eliminating slack in the cable.

In at least one embodiment, a method of providing an automated coaching message to a user of a portable electronic device includes determining first information corresponding to a health-related action for the user of the portable electronic device, transmitting the first information from the portable electronic device to a remotely located computing device, determining whether a coaching message should be provided, and receiving an automated coaching message based on the first information.
摘要:
Embodiments include a method comprising providing a primary transceiver, and a plurality of secondary transceivers spatially distributed throughout a transceiver field; and executing a setup-routine comprising a wave-routine including: the primary transceiver transmitting a cascading identification command to at least one initial secondary transceiver, wherein the identification command holds instructions for the secondary transceiver to short-range retransmit a same or modified copy of the identification command indiscriminately to neighboring secondary receivers, provided no such retransmission of the identification command was effected during a wave period immediately preceding reception of the identification command by the secondary transceiver, so as to effect a travelling wave of secondary transceivers retransmitting the identification command.
摘要:
A system and method for distributed scheduling of transmissions between device-to-device (D2D) communications is disclosed. The distributed scheduling method employs a distributed scheduling structure in which device identifiers rather than connection identifiers are used to enable scheduling of a D2D data transfer between devices in a wireless neighborhood. The novel distributed scheduling structure is scalable to a larger number of D2D devices than is feasible with a connection identifier-based tone matrix.

Technology for communicating user equipment (UE) power consumption configurations is disclosed. One method can include selecting, at the UE, a Power Preference Indication (PPI) state of a power consumption configuration of the UE. The UE can receive, from a source evolved node B (eNB), instructions to begin a PPI Prohibit Event Interval during a handover from the source eNB to a target eNB, wherein the UE cannot send the PPI state to the source eNB during the PPI Prohibit Event Interval. The UE can send the PPI state to the target eNB after the PPI Prohibit Event Interval ends and handover has either successfully completed or failed from the source eNB to the target eNB.
