    Abstract: An exclusively digital timing engine that measures extremely short time intervals for use in time of flight systems such as laser range finding systems. This exclusively digital timing engine minimizes the use of high speed, high cost components by employing a novel time multiplexing scheme to execute each of the primary time of flight functions: frequency synthesis, range gating, and time of flight interval measurement. In addition, the timing engine incorporates a random time delay scheme which enhances the resolution of the time interval measurement.

    Abstract: Apparatus, systems and methods for reducing feedback in a hearing aid that includes a transducer configured to detect sound, a sound processor configured to process signals from the transducer, a receiver configured to receive signals outputted from the sound processor, and an acoustic feedback reduction system. The acoustic feedback reduction system is configured to provide signals to the sound processor to produce a null targeting signal steerable toward a source of feedback. Securing mechanisms for space access devices, such as an audio signal transmitting device, include a plurality of outwardly projecting members that are configured to transition from a relaxed state to a securing state when the space access device is inserted into an internal space or opening that has an inside diameter smaller than an outside diameter of the outwardly projecting members in the relaxed state. The outwardly projecting members securely engage a surface of the internals space, conform to the shape and size of the internal space, and modulate at least one of the attenuation and frequency of audio signals and/or differentially acoustically impede audio signals transmitted through the securing mechanism and/or internal space and the space access device, without fully occluding the internal space.

    Abstract: An audiometric apparatus including a stimulus generator (12) for transmitting at least one true random stimulus sequence to a subject's inner ear, through a transducer (14) and an earpiece (18), and a sampling member (24) for detecting the response signal returned from the subject's inner ear, and received by a microphone (20), in response to the stimulus sequence. The response signal has at least a first waveform. The sampling member includes a waveform reconstruction mechanism for reconstructing the first waveform. The reconstruction mechanism includes a mechanism for applying a plurality of true random frequencies to the response signal. An analyzer (10) controls the stimulus generator and analyzes the response signal.
