The invention provides an intelligent heartbeat keeping method and system. The method comprises the steps that a heartbeat test is conducted according to a current heartbeat packet time interval when it is monitored that intelligent heartbeat self-adaptive computing conditions are met; when test success conditions are met, a predetermined heartbeat increased step length is added to the current heartbeat packet time interval to serve as a new current heartbeat packet time interval, and the step that the current heartbeat packet time interval is adopted to conduct the heartbeat test is executed again; when test failure conditions are met, a stable heartbeat packet time interval is determined according to the current heartbeat packet time interval. According to the scheme, a heartbeat packet time interval which adapts to a current network environment, can maintain network connection and is as large as possible can be obtained; due to the fact that the heartbeat packet time interval is as large as possible, the electric quantity, flow and network resources can also be saved to some extent.

A method and apparatus for concurrency testing within a model-based testing environment is provided. One implementation involves concurrency testing within a model-based software system testing environment, by receiving concurrent test service requests; duplicating a model representing software under test, based on the number of requests; sending the concurrent requests to each of the duplicated models sequentially but in different orders; storing the outcomes of each of the models; comparing the outcomes from the models to the outcome from the software system under test; and if all comparisons fail, then indicating test failure.

Alarm tests are disclosed which use alarm test signals to assess alarms provided by medical devices. Especially relevant are implanted devices that monitor cardiac activity and provide notification in response to medically relevant events. Alarm tests can occur periodically, or in response to a patient, doctor, or remote party initiating the alarm test. Alarm tests can also occur during the actual alarms issued to detected medical events. Alarm tests lead to pass or fail results, which in turn may cause operations to contingently occur. Alarm test failure in the auditory, visual, or tactile modality, may cause an alternatively defined alarm signal to be used as back-up. Alarm test logs can store alarm test results, including quantification of the measured alarm signal. Rapid alarm tests are described, as are various methods of accurately measuring characteristics of the test signal in ambulatory patients, which are especially relevant to a vibration alarm.

An automated emergency power supply system (EPSS) and testing solution that records generator load values and engine exhaust temperature values to evaluate whether an EPSS test satisfies legislated test criteria. The EPSS test is carried out under software control, which initiates a test by instructing an automatic transfer switch (ATS) to change its status to a test status, causing the essential loads to be powered by a generator instead of a main utility power source. Power monitors record the ATS and generator status during the test as well as electrical parameter data from the ATS and generator and exhaust temperature data and other engine parameter data from the generator. When the test is concluded, the ATS is instructed to return the status to normal so that power delivery is resumed from the main power source. The electrical and engine parameter data is analyzed and compared against legislated test criteria to determine a pass/fail result of the EPSS test.
