Abstract: Multi-stage sporting events, such as triathlons, can present particular challenges regarding collection and processing of exercise data. For example, the general length of certain multi-stage sporting events can be problematic regarding battery life for conventional tracking devices, particularly if such devices include a relatively high quantity of sensors and/or sensors that consume particularly high amounts of power during use. This disclosure presents power management functionality to address this challenge. Multi-stage sporting events can also present challenges regarding the need to switch between different sets of sensors to measure particular parameters for a given activity. This disclosure present functionality for automatic touchless transitioning between stages of an event.

Abstract: An application services broker includes a plurality of adapter modules, each of which are associated with a respective application service. Application service data is received from a first application service and converted to a first message having a predefined message format by a first adapter module associated with the first application service. The first message is sent from the first adapter module to a second adapter module associated with a second application service. The first message is converted to application service data for the second application service by the second adapter module.

Abstract: The disclosed system for extracting desired information from a speech signal includes means for taking overlapping samples of an utterance, computer means programmed to test each sample to determine whether it is voiced or unvoiced and for performing the following operations on each voiced sample: applying a 30 ms. Hamming window to smooth the edge of the signal and to ensure that false artifacts will not be present in the following processing stage, obtaining a magnitude spectrum using at least 1024 points Fast Fourier transform, obtaining the log of the magnitude spectrum, compressing the spectrum, performing a three-point filter algorithm a suitable number of times, expanding the spectrum so obtained and locating the dominant peaks in the resulting spectrum to give the information content contained in said speech signal. The specification also discloses the time equivalent of the above method. The transformed spectrum is smoothed to suppress low amplitude peaks at harmonics of the pitch frequency.
