Abstract: Methods and devices for flexible and adaptable outputting of audio files in text or audio format based on certain parameters are described. Before delivering an acquired audio file to a user, the methods and devices described herein detect a current value of a pre-specified parameter, such as an environmental noise parameter, a mute setting parameter, a ring tone setting parameter, an audio/video playback parameter, or a setting parameter of an application acquiring the audio file, and compare the current value of the pre-specified parameter with a preset condition for the same parameter. The methods and devices described herein with output the audio file or a text file created from the audio file depending on the result of the comparison.

Abstract: Method and apparatus for controlling a physical layer protocol data unit (PPDU) transmission rate of a physical layer in a first terminal are provided. The method includes: obtaining a media access control protocol data unit (MPDU) retransmission frequency of the first terminal in a first period, where the first terminal is a station or an access point in a wireless network; if the MPDU retransmission frequency is less than a frequency threshold, promoting the PPDU transmission rate in a second period; and else, suppressing the PPDU transmission rate in the second period, where the second period is following and adjacent to the first period along a time axis. The PPDU transmission rate may be adjusted adaptively according to a channel's practical transmission state, the physical layer rate may be prevented from decreasing continuously in noisy channel environment, and a throughput rate may be improved in real time.

Abstract: Method and apparatus for controlling startup of RTS/CTS mechanism is provided. The method includes: obtaining a noisy level of a channel based on the number of first data received by a first terminal in a first period, where the first terminal is a STA or an AP in a wireless network, and the first data include aggregation frames or non-aggregation frames; and if the noisy level is greater than or equal to a noisy level threshold, controlling the first terminal to start up the RTS/CTS mechanism when data is transmitted in a second period which is following and adjacent to the first period along a time axis. The noisy level of the channel may be obtained in real time, and the RTS/CTS mechanism may be controlled to be started up reasonably in real time, so that channel resources is utilized sufficiently, and a throughput rate is improved.

Abstract: Method and apparatus for controlling CCA threshold of a wireless communication channel is provided. The method includes: obtaining a noisy level of the channel based on the number of first data received by a first terminal in a first period, the first terminal being a STA or AP in a wireless network, and the first data include aggregation frames or non-aggregation frames; and adjusting the CCA threshold the first terminal uses in data transmission in a second period based on the noisy level. The first terminal may adaptively detect the noisy level of the channel, and the CCA threshold may be selected reasonably based on the noisy level, which enables the first terminal to obtain an opportunity of accessing the channel in time when it needs to send data, enhance the first terminal's competition ability of occupying channels, and improve a throughput rate.

Abstract: Method and apparatus for controlling length of aggregation frames in a wireless network is provided. The method includes: obtaining a noisy level of a channel based on the number of first data received by a first terminal in a first period, the first terminal being a STA or AP in the wireless network, and the first data include aggregation frames or non-aggregation frames; and determining length of an aggregation frame to be transmitted by the first terminal in a second period based on the noisy level, where the second period is following and adjacent to the first period along a time axis. The first terminal may detect the noisy level and select the length of the aggregation frame based on the noisy level. Thus, inter-frame collision and interference in the channel may be reduced, channel resources may be well utilized, and a throughput rate may be improved in real time.

Abstract: The present disclosure introduces new multi-functional vibrating devices, methods of using the devices, and methods of manufacturing the devices. A multi-functional vibrating device can include one or more actuators, each paired with an amplifier capable of converting small lateral vibration into large vertical vibration. The present disclosure also involves interactive information acquisition technologies and assistive technologies, particularly devices, methods, and systems for tactile information transfer and acquisition. Some embodiments incorporate multi-functional vibrational devices, methods, and systems to achieve unique structural and operational characteristics—such as high-resolution, robustness, versatility, compactness, and/or rapid refresh rates—for communicating information. Some embodiments can convert information from a format that is less convenient and/or accessible in some cases (e.g., visual or audio) to an intuitive and/or private format (e.g., tactile patterns and motions).
