Abstract: Introduced here is a wearable audio system including modular ear-cup and ear-bud that can be attached and detached to the user together, or independently of each other. Further, the modular ear-cup and ear-bud can operate together, or independently of each other. The wearable audio system can perform active noise cancellation by measuring noise inside the ear-cup and/or the ear-bud, computing the noise canceling sound, and forwarding the noise canceling sound to a speaker inside the ear-cup and/or the ear-bud. The wearable audio system can be wirelessly charged while operating, thus allowing the user to continuously listen to music more than previously possible. The wearable audio system can optimize power consumption by redistributing power intensive tasks to power sources with the highest amount of power. Further, the ambient sound outside the ear-cup can be measured and played by the speakers in the earbud allowing the user to hear the surrounding environment.

Abstract: Introduced here are systems and methods to enable recording artists and engineers to specify exactly how the audio track should be played as well as perceived by the user in the case where the frequency transfer functions of the sound playback system and/or listening mechanisms (user's own hearing) can be measured and compensated for. For example, the acoustic environment during recording and mastering can be measured, and the measurements can be recorded in an inaudible portion of an audio track. The acoustic environment can include speaker frequency, distortion, reverberation, channel separation, room acoustics, etc. In addition, a hearing profile of the audio creator, such as the recording artist, sound engineer, mastering person, etc., can be included within the inaudible data. Further, the acoustic environment and/or the hearing profile of the audio consumer can also be used to modify the audio prior to reproducing the audio to the audio consumer.

Abstract: Introduced here are systems and methods to increase accuracy of speech recognition by utilizing multiple sensors placed at multiple speech transmission regions such as a user's lips, throat, ear canal, etc. The various speech transmission regions are better at transmitting certain phonemes, and a sensor placed close to a particular speech transition region can more accurately detect the phoneme transmitted through the particular speech transmission region. For example, a microphone placed close to the lips can better detect labial phonemes such as m, n, p, and b, than a microphone placed close to the throat. Further, disclosed here are ways to reduce energy consumption while performing speech recognition.

Abstract: Presented here is an audio device, such as a headphone, that can create, maintain and use secure data. The secure data can include an amount of time that the user has used the audio device and/or an amount of time allocated to the user. When the amount of time the user has used the audio device exceeds the amount of time allocated to the user, the audio device can stop emitting the audio. The secure data can also include a hearing profile of the user, which ca uniquely identify the user. The secure data associated with the headphone can be encrypted to prevent tampering.

Abstract: Presented here is an apparatus and method to increase a listener's enjoyment of sound by combining in-ear headphones with either over-ear headphones or on-ear headphones. One embodiment is headphones that include an ear-cup with an ear-bud protruding toward the listener's ear-canal. The ear-cup substantially surrounds the listener's ear and delivers sub sonic and low-frequency vibrations to the listener's skin stimulating a vibrotactile response. The ear-bud is disposed within the listener's ear canal and delivers a full range of audible frequencies. Additionally, the headphones, along with the ear-cup in the ear-bud, provide both passive and active noise cancellation.

Abstract: A wireless device configured as a group owner determines whether all client devices paired with the group owner are currently associated with the group owner. If all paired client devices are currently associated with the group owner, the group owner enters a first mode in which the group owner is in an active mode (powered up to communicate) during a first portion of a beacon interval and is in a low power mode (in which no communication occurs) during a second portion of the beacon interval. If not all paired client devices are currently associated with the group owner, the group owner enters a second mode in which the group owner is in the active state during the first portion and at least part of the second portion of the beacon interval. The group owner and client devices are configured to operate as master and slave.

Abstract: It is possible to provide a radio communication terminal device, a radio communication base station device, and a radio communication method capable of rapidly completing a handover even during DRX/DTX. In the devices and the method, a terminal (100) transmits a quality measurement result to a base station (150) at an Active interval. Here, the terminal (100) sets the DRX/DTX interval to a short interval since performance of a handover is predicted. The base station (150) which has received the quality measurement result transmitted from the terminal (100) recognizes that the terminal has set the DRX/DTX interval to a short interval and transmits a handover instruction to the terminal (100) at the Active interval, considering the shortened DRX/DTX interval.

Abstract: A base station receives an uplink data packet from a user equipment based on a synchronous hybrid automatic repeat request (HARQ) protocol, and transmits a first information element and a second information element in parallel to the user equipment. The first information element indicates whether to perform a retransmission of the uplink data packet, and the second information element indicates modulation and coding scheme (MCS) for the retransmission. The base station receives the retransmission from the user equipment according to the modulation and coding scheme. The first information element is for example an ACK/NACK feedback message.

Abstract: The present invention relates to a method and transmission apparatus for transmitting broadcast system information in a mobile communication system. Further, the invention relates to a method and mobile terminal receiving the broadcast system information. To provide an improved method for broadcasting broadcast system information the invention suggests mapping different partitions of broadcast system information to a shared transport channel or a broadcast transport channel for transmission. The mapping may take into account parameters inherent to the mobile terminals to which the broadcast system information is to be transmitted and/or parameters inherent to the different partitions of broadcast system information.

Abstract: A multi-sensor gas detector includes a solid state heatable gas sensor, and at least one, different, infrared gas sensor. Emitted radiant energy from a heated surface of the solid state gas sensor, incident on the infrared gas sensor generates an output signal indicative thereof.

The evaluation circuits can be implemented with a programmable processor and associated, executable control software to establish the presence of a target gas. One or more gas detectors can be incorporated into a regional monitoring system that includes a control unit coupled to a plurality of fire, smoke or gas detectors.
