Abstract: A sleep-retraining method includes monitoring, via a sleep-retraining beanie, electrical brain-activity of a user during an initial sleep session. The electrical brain-activity is reflected in the form of brain-activity data. The method further includes receiving, via an electronic device, physical-activity data for the user that is indicative of a physical activity of the user occurring after the initial sleep session. The method further includes, based on the brain-activity data and the physical-activity data, suggesting an optimal sleep session for the user that has an improved sleep quality relative to the initial sleep session.

Abstract: A method includes receiving, at a first computing device, data associated with the sleep session. The method further includes transmitting a first portion of the data associated with the sleep session to a second computing device. The second computing device is configured to analyze the first portion of the data to generate an initial set of one or more stimuli to be applied to the individual during the sleep session. The method further includes receiving, at the first computing device, the initial set of one or more stimuli from the second computing device. The method further includes determining, by the first computing device, a final set of one or more stimuli to apply to the individual during the sleep session based at least in part on the initial set of one or more stimuli and a second portion of the data associated with the sleep session.

Abstract: An apparatus for managing contention in a communications system, the apparatus comprising a processor and a non-transitory computer readable storage medium storing programming for execution by the processor. The programming may include instructions to receive a ranging code from a device in a ranging channel, the ranging code corresponding to a current ranging attempt. The programming may further include instructions to broadcast a message acknowledging reception of the ranging code. The programming may further include instructions to receive a ranging request message from the device, the ranging request message comprising a ranging retries parameter that specifies a number of ranging retries that the device performed during the current ranging attempt.

Abstract: In a system and method of adapting an ECSD connection, interruption times and data loss due to a change in the modulation, coding scheme, and number of timeslots of the connection may be minimized or eliminated. The interruption times and data loss may be minimized or eliminated by allocating a peak number of substreams for a given mobile radio connection based on a user requested data rate and/or the number of timeslots used to realize the user requested data rate. Data loss may also be minimized or eliminated by using in-band signaling to signal a change in the modulation, coding scheme, and/or number of timeslots.
