No overlap may be provided between the field of view of the radiation detector(s) and the emitter(s), such as by providing a blocking element.

There is provided an electronic device having Bluetooth communication function. The electronic device confirms whether a current packet received in a receive slot is a retransmitted packet according to a SEQN bit in the packet header so as to determine whether to continuously turn on an RF receiver in the receive slot or early turn off the RF receiver to save power.

Aspects of the subject technology relate to a device including a microphone, a filter and a processor. The filter receives an audio signal including ambient noise and a voice of a user of the device from the microphone. At least a portion of ambient noise is filtered from the audio signal. The processor determines a level of the ambient noise in the received audio signal and dynamically adjusts a gain applied to the filtered audio signal based on the level of the ambient noise.

The embodiments of the present disclosure disclose an acoustic apparatus. The acoustic apparatus may include a support assembly. The support assembly may include a first portion and a second portion. When a user is wearing the acoustic apparatus, the first portion may be hung between a first side of an ear and a head of the user, the second portion may contact a second side of the ear. The first portion may cause the second portion to provide a compressive force on the second side of the ear.

The present disclosure provides a method for obtaining a vibration transfer function from a sound generation unit to other positions. The method comprises: generating a first sound and a second sound based on a first test audio signal and a second test audio signal; outputting a first feedback signal after receiving the first sound, the first feedback signal including a signal transmitted from a sound generation unit to a first position through vibration transmission path and air conduction transmission path; outputting a second feedback signal after receiving the second sound, the second feedback signal including a signal transmitted from the sound generation unit to a second position through air conduction transmission path; determining the vibration transfer function from the sound generation unit to the first position based on the first test audio signal, the second test audio signal, the first feedback signal, and the second feedback signal.

An electronic device may include one or more radios and one or more antennas. Radio-frequency transmission lines may couple a radio to a corresponding antenna. To more efficiently form a radio-frequency transmission line, the radio-frequency transmission line may be formed from interconnected conductive traces distributed between a plurality of printed circuits. By integrating transmission line structures onto printed circuits that also serve other functions, the device can require less space to implement a radio-frequency transmission line. While one or more of these printed circuits may individually be unsuitable to implement a radio-frequency transmission line with a particular impedance, the composite impedance of these transmission line structures across the printed circuits, when properly configured, may provide a radio-frequency transmission line with the particular impedance.

A method utilized in a wireless device used to wirelessly receive and play audio information includes: receiving a data packet stream transmitted from an audio source; monitoring a data amount of at least one buffer of a memory of the wireless device; and tuning an audio clock frequency dedicated for playing audio samples if the data amount of the at least one buffer deviates from a specific data amount level.
