Hardware-efficient auto-reconfigurable hearing aids using 3-level octave interpolated filters for auditory compensation applications.

A reconfigurable hearing aid is a generic type that can be used for various hearing disabilities without modifying the device hardware. This requires several trials to identify the best matching with the impaired person's audiogram. The objective of this paper is to propose a novel reconfigurable hearing aid of low complexity with auto-adapting capability which makes it suitable for different types of hearing disabilities ranging from mild to severe intensities.

A low-complexity 3-level filter bank design for effective restoration of audibility in digital hearing aids.

A low-complexity method for sub-band decomposition of audio signals in digital hearing aids for audibility restoration applications is described in this paper. This 3-level filter bank is capable of generating an array of 4, 8, and 16 sub-filters from a single finite impulse response filter. The prototype low pass filter is accomplished using the Parks McClellan algorithm with a minimal number of 28 multipliers.

An analysis of legally uncertified deaths in England and Wales, 1979-2002.

Legally uncertified deaths are unusual, with not more than a few hundred occurring each year. However, they are of interest because they have increased in number over the last 25 years. This article examines the circumstances under which deaths become legally uncertified and presents information on their characteristics and recent trends.

[Ofuji's papuloerythroderma: two cases treated with azathioprine].

Background: Ofuji's papuloerythroderma is a rare disorder, characterized by a generalized pruriginous eruption, sparing the folds. It predominates in the elderly. The pathology is still unknown but associations with lymphoma have been described.
