We present a novel method for mapping and localization in indoor environments using a wearable gesture interface. The ear-mounted FreeDigiter device consists of an infrared proximity sensor and a dual axis accelerometer. A user builds a topological map of a new environment by walking through the environment wearing our device. The accelerometer is used to identify footsteps while the proximity ...

OBJECTIVE To determine the level of awareness and practice of use of protective eye devices among welders in Ile-Ife. METHODS This is a cross-sectional descriptive study of 405 consenting welders. A pretested proforma was utilized to obtain information on sociodemographic characteristics, as well as awareness and use of protective eye device. RESULTS The age of the respondents ranged from 1...

In this article, we present a simple, rapid prototyped polystyrene-based microfluidic device with three-dimensional (3D) interconnected microporous walls for long term perfusion cell culture. Patterned 3D interconnected microporous structures were created by a chemical treatment together with a protective mask and the native hydrophobic nature of the microporous structures were selectively made...

In this paper, we describe a human-computer interface (HCI) system that includes an enabler for controlling gadgets based on signal analysis of brain activities transmitted from the enabler to the gadgets. The enabler is insertable in a user’s ear and includes a recorder that records brain signals. A processing unit of the system, which is inserted in a gadget, commands the gadget based on deco...

OBJECTIVES/HYPOTHESIS To determine whether betamethasone (BM) reduces the cochlear toxicity of otic gentamicin (GM) if given together. STUDY DESIGN Controlled animal study. METHODS Thirty-four mice were assigned at random to receive intratympanic injections of either 0.1 % BM (11 mice), 0.3% GM (13 mice), or a combination of both (GM/BM) with benzalkonium chloride (10 mice) in the left ear ...

Voice activity detection (VAD) aims for detecting the presence of speech in a given input signal, and is often first step voice -based applications such as communication systems. In context personal devices, own (OVD) sub-task VAD, since it targets person wearing device, while ignoring other speakers interference signals. This article summarizes recent single multi-microphone, multi-sensor, hea...

ing creating a radical mastoid cavity, obliteration of the eustachian tube, obliteration of the mastoid cavity with free abdominal fat, and permanent closure of the external ear canal. This technique has been evaluated for a period of less than 1 year, but seems to offer a real potential of disease eradication. In addition to this procedure, a device for sealing the cochlea at the point of entr...
