Abstract: Systems and methods for presenting audio using an audio system supporting multiple modes of operation are disclosed. In some embodiments, elements of the audio system are configured to operate in the different modes. For example, the audio system is configured to operate in a first mode and a second mode. The audio system may be operating in the first mode or the second mode based on an application running on a system or a signal generated by the system.

Abstract: A method for measuring and logging the performance of a wheeled vehicle suspension system by measuring the dynamic performance of at least one component of said vehicle suspension system, the method including the steps of: setting the vehicle on a pre-determined path and within a pre-determined speed range; causing the suspension of said vehicle to be displaced by a substantially predetermined amount by causing the wheels of the vehicle to roll over one or more objects of known size on said path; measuring the displacement of said at least one suspension system component relative to the sprung mass of the vehicle and/or one or more fixed objects in response to said displacement; measuring the oscillation frequency of said at least one vehicle suspension system component in response to said displacement; and determining the suspension damping characteristics relating to the at least one vehicle suspension system component using the displacement and frequency measurements.

The analysis is combined with an algorithm that recommends and enables the purchase of specific products that best address the results from the analysis.

Abstract: A system and method predicts events in a computer system. The system and method includes a controller that receives a crash profile. The controller generates granular information that identifies data indicative of a potential server cluster failure in an enterprise system without needing to identify an originating cause of the potential server cluster failure. The system and method trains a model by sampling portions of a profile that may include directives and data indicative of a normal operating state and a conditioned preamble operating state. The system and method provides a trained model to a prediction engine. The system and method modifies an allocation of computing resources in response to the prediction of the potential server cluster failure by the prediction engine monitoring one or more servers of a server cluster.

Abstract: Apparatuses that operate as both a public address speaker and a wireless access point (AP) for mounting to a ceiling or wall. The compact public address access points described herein may include an AP housing, enclosing a radio (e.g., a 3×3 MIMO radio) and antenna, that is coupled to a speaker assembly including a speaker, a conical acoustic reflector positioned between a front of the speaker and the housing of the AP, and an annular region comprising a concave inner wall facing the conical acoustic reflector. Although the AP is nested atop the front of the speaker, the speaker may produce high-quality sound with accurate voice reproduction without interfering with the operation of the wireless transmission of the AP. Methods of operating and installing these apparatuses are also described.

Abstract: An ear tip is disclosed that comprises an annular flange having a first end tapering downwardly to a second end and having a teardrop curve lateral cross section running from approximately the upper end to the lower end. An inner body extends internally from the upper end within a hollow interior defined by the flange toward the lower end. An acoustic channel extends through the inner body. The flange at least partially occludes an ear canal from ambient noise and creates at least a partial air seal in the ear canal and the acoustic channel is configured to allow the passage of sound into the ear canal when the inner body is connected with a sound source.

Abstract: Method of reducing performance variability of membrane scaling devices. Scaling device performance uncertainty is reduced, thereby reducing the scaling safety factor, by specifying a narrow range or subset of the set of all qualified manufactured membranes for installation into scaling devices. In certain embodiments, the scalability factor is reduced by determining where within the performance distribution a particular membrane lies, and adjusting the scaling factor accordingly.
