BACKGROUND Implantable heart rhythm devices are susceptible to interference in hospitals where electromagnetic interference (EMI) sources are ubiquitous. CASE DESCRIPTION We report three cases in which EMI from the external defibrillator caused the inability to interrogate Boston Scientific cardiac resynchronization therapy-pacemaker (CRT-P) devices. We have documented interference with the B...

ABSTRACT: SRAM area is expected to exceed 90% of overall chip area because of the demand for higher performance, lower power, and higher integration. To increase memory density, memory bitcells are scaled to reduce their area by 50% each technology node. High density SRAM bitcells use the smallest devices in a technology, making SRAM more vulnerable for variations. This variation effect the sta...

‎In this paper‎, ‎a coherent system consisting of non-identical dependent active components and‎ ‎equipped with non-identical dependent standby components is considered‎. ‎The main object of this study is the random quantity‎ ‎which account the number of surviving standby components when the system‎ ‎is failed‎. ‎We represent the distribution function of the corresponding random variable in ter...

BACKGROUND Postvention services aim to ameliorate distress and reduce future incidences of suicide. The StandBy Response Service is one such service operating in Australia for those bereaved through suicide. Few previous studies have reported estimates or evaluations of the economic impact and outcomes associated with the implementation of bereavement/grief interventions. AIMS To estimate the...

This paper presents a new fault tolerance scheme suitable for humanoid robot applications. In the future, various tasks ranging from daily chores to safety-related tasks will be carried out by individual humanoid robots. If the importance of the tasks is different, the required dependability will vary accordingly. Therefore, for mobile humanoid robots operating under power constraints, fault to...

In this paper, we propose a five-transistor (5T) static random access memory (SRAM) that can be read and written reliably with the assistance of read/write circuits. The read/write circuits include a voltage control circuit, a pre-charging circuit and a standby start-up circuit. The voltage control circuit is connected to the sources corresponding to driver transistors of each row memory cells....

Cascade reliability model is a special type of Stress Strength model. The n Cascade system is a h ierarch ical standby redundancy system, where the standby component taking the place of failed component with decreased value of stress and independently distributed strength. This paper deals with the generalized exponential distribution with cascade system.

Some theoretical evaluation methods of mean time to failure (MTTF) in 2-component standby redundant system with priority have been suggested under the prerequisite that the probability distributions of failure and repair times in each component are respectively specified by the explicit functions. However, this prerequisite might be considerably strict in practical scenes. If we cannot identify...
