A Vibratory Alarm for a Ventilator

The evolution of vocal alarm communication in rodents

On encountering a predator, many species emit potentially risky vocalizations known as alarm calls. We evaluated the relative importance of two adaptive hypotheses on the evolution of calling: (1) communicating to predators, which may function by deterring pursuit and hence increasing individual survival, and (2) an alternative nepotistic hypothesis for alarm calling whereby callers obtain dire...

Improving Clinical Alarm Management: Guidance and Strategies.

This article focuses on the type of problems that lead to false or nonactionable clinical alarms and the type of data that can help identify which of these alarms are most prevalent in specific units in healthcare facilities. The process of identifying necessary data is first described, as this activity will drive later choices on capturing data. This article also discusses how to use the data ...

Designing Empowering Vocal and Tangible Interaction

Our voice and body are important parts of our self-experience, and our communication and relational possibilities. They gradually become more important for Interaction Design due to increased development of tangible interaction and mobile communication. In this paper we present and discuss our work with voice and tangible interaction in our ongoing research project RHYME. The goal is to improve...

Heterospecific alarm call recognition in a non-vocal reptile.

The ability to recognize and respond to the alarm calls of heterospecifics has previously been described only in species with vocal communication. Here we provide evidence that a non-vocal reptile, the Galápagos marine iguana (Amblyrhynchus cristatus), can eavesdrop on the alarm call of the Galápagos mockingbird (Nesomimus parvulus) and respond with anti-predator behaviour. Eavesdropping on com...

Improving Equipment Maintainability via Alarm Threshold Optimization

The Operations Technology Center (OTC) is responsible for the systems used to manage and maintain the AT&T long distance network. In this paper we describe an effort within the OTC to improve the maintainability of AT&T’s 4ESS switches, by optimizing the thresholding rules within the operation support system responsible for maintaining these switches. This optimization task required us to firs...
