  • Patent number: 10548510
    Abstract: A computer implemented system and method for performing a quantitative balance assessment on a subject are described. The method comprises instructing the subject to perform an assessment task with at least a first kinematic sensor mounted on the subject's head; collecting kinematic sensor measurements, comparing the measurements to a threshold value; summing the total number of kinematic sensor measurements that exceed the threshold value to generate a numerical score indicative of the subject's postural stability. The system makes use of only kinematic data collected from the wireless sensors to quantify BESS, and generate a BESS score, without any other physiological variables such as forward sway.

  • Patent number: 9106987
    Abstract: Embodiments of the invention include a micro speaker assembly that has two drivers, each having a separate yoke, set of magnets, voice coil, and acoustic diaphragms. One driver may produce high frequency (HF) sound while the other produces low frequency (LF) sound. The two drivers may be packaged, side-by-side, within the same micro speaker acoustic enclosure. The drivers may have their respective magnet systems physically connected to each other, in order to enhance heat transfer from one to the other. In particular, a thermally conductive portion or bridge may be used to directly join or thermally connect adjacent edges of the yoke portions of the two magnet systems, in order to enhance heat transfer between the first and second micro speaker drivers. Thus, the assembly can handle more power without overheating. Other embodiments are also described and claimed.

  • Patent number: 8847779
    Abstract: Various inventive features are disclosed for efficiently generating regulation-compliant audible alerts, including but not limited to 520 Hz square wave alert/alarm signals, using an audio speaker. One such feature involves the use of a non-linear amplifier in combination with a voltage boost regulator to efficiently drive the audio speaker. Another feature involves speaker enclosure designs that effectively boost the output of the audio speaker, particularly at relatively low frequencies. Some of the disclosed speaker enclosure designs rely on an interference effect and/or a resonance effect to transfer energy from higher-order harmonics downward to the fundamental frequency and lower-order harmonics. These and other features may be used individually or combination in a given alarm-generation device or system to enable regulation-compliant audible alerts to be generated using conventional batteries, such as AA alkaline batteries.

    Abstract: A method of configuring an array of speaker elements is disclosed. The method computes a sound that pressure level at various points in the venue and is evaluated by various objective functions. The configuration of a candidate array is changed, for example by the orientation or position of the speakers and the sound field is recalculated. The process is then iterated until an acceptable configuration is found. The real physical array of speakers is then configured in that manner. The method also provides a 3D plot of the sound pressure level displayed against freguency and position in the venue.
