Effects of Simultaneous Alarms on Resolution Heuristics
… that an alarm contained within a larger array of alarms should not be evaluated individually. Due to the increasing use of multiple alarms in complex environments such as operating rooms and cockpits (Konkani, Oakley, & Bauld, 2012; Woods, Suter, & Billings, 1997), it is important to identify …

Using Eye-tracking to Acknowledge Attended Alarms
… alarm floods would be altering the salience of alarms that operators might already notice, thereby reducing the disruption on workflow and attention for managing uninformative alarms. This research investigated the central hypothesis that eye fixations could supply passive input to acknowledge …

Temporal Patterns for Burglar Alarms and Police-coded Burglaries
… when burglaries are actually occurring. Burglar alarms are also important as manifestations of the fear of crime and as attempts to reduce crime. As the fear of crime has increased the number of burglar alarms has increased also. Along with the increase in alarms came an increase in alarm calls …

An Evaluation of Urine Alarms in Intensive Toilet Training Programs
… protocols include audible, urine-detecting alarms as part of comprehensive, reinforcement-based programs with effective results. However, the independent effects of urine-detecting alarms are unclear. Urine alarms may contribute to toilet training effects through reinforcing or punishing …

False Alarms in the Forecasting of Solar Energetic Particle Events
… but which failed to do so, may be termed “false alarms”. In this work, two simple SEP forecasting algorithms are defined: one (algorithm A.1) is based upon the observation of a magnetically well-connected CME with a speed of 1,500 km/s or greater (a ``fast CME''), and the other (algorithm A.2) is …

Auditory Alarms In The Intensive Care Unit: Experimental And Observational Studies
… A further feature of sounds used for auditory alarms is that there is, at present, no agreement between manufacturers on the types of sounds used. This means that the same item of equipment can have different alarms if produced by different manufacturers. Subsequently there is the potential for …

The human factors aspects of alarms in human supervisory control tasks.
This research thesis is concerned with the human factors aspects of industrial alarm systems within human supervisory control tasks. Typically such systems are located in central control rooms, and the information may be presented via visual display units. The thesis develops a human, rather than …

Characterization of monitoring alarms in a community hospital intensive care unit
Because the vast majority of monitoring alarms in the adult intensive care unit (ICU) do not require intervention, care providers are slow to respond to all alarms, endangering patients. We collect, characterize, and analyze alarms, alarm annotations provided by clinical staff while responding to …

Contextual Factors Influencing the Acute Care Registered Nurse's Response to Clinical Alarms
Nurses are faced with a multitude of clinical alarms on a daily basis. There is an inherent expectation that upon hearing an alarm the nurse will immediately respond to assess the situation and initiate appropriate action to correct the problem. Yet this does not always occur. Issues with alarm …

Simulation and mathematical notation of alarms unit for computer assisted resuscitation algorithm
… on the blood pressure of the patient. The alarms unit of CARA was simulated for the infusion pump in which the occurrence of alarms depends on the various criteria the infusion pump encounters when saline is being infused into patients. Various criteria may vary from an air bubble in the …

Drivers' Ability to Localize Auditory and Haptic Alarms in Terms of Speed and Accuracy
… ability to localize auditory and haptic (touch) alarms in terms of speed and accuracy. Thirty-two subjects, balanced across age (20-30 years old and 60-70 years old) and gender, participated in the study. Subjects were screened for minimum hearing of 40 dB for 500 Hz through 4000 Hz auditory …

Problems With Auditory Alarms in Anesthesia and Tests of a Proposed Solution: Multimodal Multitask Performance With an Auditory Display
Auditory alarms are used pervasively for patient-monitoring equipment to warn of potential problems, despite widely reported shortcomings in their design. Problems include high rates of false alarms; interruptive, uninformative, stress-inducing acoustic profiles for alarm sounds; and alarms that …

Azimuthal Localization and Detection of Vehicular Backup Alarms Under Electronic and Non-Electronic Hearing Protection Devices in Noisy and Quiet Environments
… earmuffs for workers if localizing backup alarms is important. In the first experiment, listeners' feeling of comfort for each hearing protector was assessed subjectively by using a comfort rating scale. In addition, a subjective assessment for listeners' confidence in their localization …

Fall Prevention: Responder 5 Bed Connectors
… fall prevention intervention, Responder 5 bed alarms, was explored. A literature review on falls was conducted to study the effectiveness of bed alarms. Capezuti et al. (2009) found bed alarms to be error prone and stress the importance of patient risk factor assessment and using bed alarms as …

Addressing the Problem of Alarm Fatigue: Enhancing Patient Safety through Cardiac Alarm Customization
… through enhanced cardiac alarm customization. Alarms are intended to enhance patient safety. However, unnecessary and non-actionable alarms contribute to alarm desensitization and fatigue, lessening response time to critical alerts. Alarm fatigue has become a growing patient safety concern and …

Food theft by deceptive alarm calls in the fork-tailed drongo
Why do animals make false alarms; are false alarms truly deceptive; and if, just as in Aesop's fable 'The boy who cried wolf' , animals can learn to ignore false alarms, why doesn't deception break down? I investigated these questions in a population of habituated and individually recognisable …

Heuristics for Improved Enterprise Intrusion Detection
… generate an overwhelming volume of false alarms, making the task of identifying genuine attacks nearly impossible. This problem is very difficult to solve even in networks of nominal size. The task of uncovering attacks in enterprise class networks quickly becomes unmanageable.</p> …

Effects of Visibility and Alarm Modality on Workload, Trust in Automation, Situation Awareness, and Driver Performance
… the clear visibility condition trusted tactile alarms more than the auditory alarms, whereas drivers in the heavy fog condition trusted auditory alarms more than tactile alarms. The findings of this investigation could be applied to improve the design of CAWS that would help improve driver …

Development and trialling of a low-power wearable fall detector
… % specificity, a false alarm rate of 0.023 false alarms/hour and a battery life of 664.9 days with a 3.7 V, 450 mAh battery. The second generation of fall detector was developed to overcome the limitations of Neon 1. Neon 2 with three variants of the fall detection algorithm, each employed a …

A model-based alarm processor for the assessment of protection systems performance
… also become unmanageable. Volumes of operational alarms, for example SCADA (Supervisory, Control and Data Acquisition) data, can reach up to 65,000 alarms within 24 hours during storm conditions. This thesis presents the use of model-based reasoning for the analysis of SCADA data for the …
