Abstract: In-ear sound pressure level, SPL, is determined that is caused by output audio being converted into sound by a headset worn by a user. The in-ear SPL is converted into a sound sample having units that are suitable for evaluating sound noise exposure. These operations are repeated to produce a sequence of sound samples during playback. This sequence of sound samples is then written to a secure database. Access to the database is authorized by the user. Other aspects are also described and claimed.

Abstract: To effectively and efficiently provide control information, a broadcast pointer channel (BPCH) may be used to identify the type and perhaps relative location of control information that is being provided in a given frame structure, such as a sub-frame, frame, or superframe. A sub-frame (or like framing entity, such a frame or superframe) may have a BPCH and a corresponding system control information segment in which control information may reside. The system control information segment may have any number of control information blocks, wherein each control information block that is present may correspond to a particular type of control information. The BPCH is used to identify the type of control information that is present in a corresponding system control information segment, and if needed or desired, the relative locations of the various control information.

Abstract: The present disclosure generally relates to user interfaces and techniques for managing audio exposure using a computer system (e.g., an electronic device). In accordance with some embodiments, the electronic device displays a graphical indication of a noise exposure level over a first period of time with an area of the graphical indication that is colored to represent the noise exposure level, the color of the area transitioning from a first color to a second color when the noise exposure level exceeds a first threshold. In accordance with some embodiments, the electronic device displays noise exposure levels attributable to a first output device type and a second output device type and, in response to selecting a filtering affordance, visually distinguishes a set of noise exposure levels attributable to the second output device type.

Abstract: A digital signal processing method for ambient sound acoustic dosimetry. Strength of a microphone signal generated by a watch worn by a user is determined and converted into a sound sample having units for sound noise exposure. This is repeated multiple times to produce a time sequence of sound samples that is written to a secure database access to which is authorized by the user. Other aspects are also described and claimed.

Abstract: Methods and systems are provided that enable an OFDM transmitter to be used for transmitting conventional OFDM or a form of transformed OFDM. A technique is provided for transforming a coded and modulated sequence of samples prior to an IFFT that enables the transformed sequence of samples to be transmitted using conventional OFDM or transformed OFDM. The selection of a transform function for transforming the coded and modulated sequence of samples may be based on optimizing the transform function for particular operating conditions between the transmitter and receiver. In some embodiments of the invention OFDM and time transformed OFDM are multiplexed in time and/or frequency in a transmission frame. In some embodiments of the invention a pilot pattern is provided in which the pilot are sent using OFDM and data is sent using OFDM and/or transformed OFDM.

Abstract: A channel descriptor management message is transmitted on a broadcast connection to a mobile terminal. The channel descriptor management message provides a format for a frame. The frame includes a resource space. The channel descriptor management message defines a plurality of channels within the resource space and allocates at least one of the channels to a plurality of users. Subsequent resource allocation messages may refer to a location within a channel rather than a location within the entire resource space.

Abstract: A mobile terminal in a wireless communication network may be one of several modes of operation. When in an idle mode, the mobile terminal may avoid a lengthy random access procedure normally associated with responding to a page from a base station, if the base station includes in the page an indication of a resource that the mobile terminal may utilize when responding to the page. Additionally, the mobile terminal may transmit an efficient location update MAC header to a base station, whether prompted to by a page from the base station or not. Furthermore, without leaving the idle mode or a sleep mode, the mobile terminal may exchange short data burst messages with a base station.

Abstract: A method for execution by a mobile station (MS) in a mobile communications network, the method comprising: receiving a first MS identifier from the network during a ranging operation involving the MS; using the first MS identifier to extract the contents of at least one message received from the network during said ranging operation; using a second MS identifier, different from the first MS identifier, to extract the contents of at least one message received from the network after said ranging operation is complete. Also, a method for execution by the base station, comprising: outputting a first message destined for the MS, the first message including a first identifier for use by the MS during a ranging operation; determining that said ranging operation is complete; outputting a second message destined for the MS, the second message including a second identifier for use by the MS in subsequent communication with the network.
