A method for determining the state of a battery, or battery pack, that is independent of the type of battery technology under test. The method employs one or more charging and discharging cycles, and measures one or more parameters of battery voltage, temperature, charging time, and charging cycle counts to produce a test value that is compared to empirical data. Based on the comparison, the state is determined, for example, on a pass / fail basis. The method may be embodied as instructions stored in memory and implemented by means of a microprocessor coupled to the memory. In another embodiment, the empirical data is stored within another memory located internal to the battery pack under test.

Secure computation environments are protected from bogus or rogue load modules, executables and other data elements through use of digital signatures, seals and certificates issued by a verifying authority. A verifying authority-which may be a trusted independent third party-tests the load modules or other executables to verify that their corresponding specifications are accurate and complete, and then digitally signs the load module or other executable based on tamper resistance work factor classification. Secure computation environments with different tamper resistance work factors use different verification digital signature authentication techniques (e.g., different signature algorithms and / or signature verification keys)-allowing one tamper resistance work factor environment to protect itself against load modules from another, different tamper resistance work factor environment. Several dissimilar digital signature algorithms may be used to reduce vulnerability from algorithm compromise, and subsets of multiple digital signatures may be used to reduce the scope of any specific compromise.

Method and system for diagnosing whether vehicular components are operating abnormally based on data obtained from sensors arranged on a vehicle. In a training stage, output from the sensors during normal operation of the components is obtained, each component is adjusted to induce abnormal operation thereof and output from the sensors is obtained during the induced abnormal operation. A determination is made as to which sensors provide data about abnormal operation of each component based on analysis of the output from the sensors during normal operation and during induced abnormal operation of the components. During operation of the vehicle, the output from the sensors is obtained and analyzed, e.g., by inputting it into a pattern recognition algorithm or neural network generated during the training stage, in order to output an indication of abnormal operation of any components being diagnosed.

Verification of a source of a package is facilitated. A data terminal certified by an authority obtains location data from a location detection component. The location data indicates a source location from which the package is to be shipped, and is detected by the location detection component at the source location. Secure package shipment information, including the location data, is provided with the package to securely convey the detected source location to facilitate verifying the source of the package. The data terminal can be a portable data terminal certified by the authority and have a tamper-proof boundary behind which resides the location detection component and one or more keys for securing the package shipment information. Upon tampering with the tamper-resistant boundary, the certification of the portable data terminal can be nullified.

A system may perform interconnect BIST (IBIST) testing on source synchronous links. The system may perform, at normal operating frequency, a source synchronous link test that tests a victim line on the source synchronous link using a transition weave pattern. The transition weave pattern causes interaction between a data transition on the victim line, previous transitions on the victim line, and transitions on the other lines of the link (the “aggressor” lines). The interaction caused may be: (i) a first crossing pulse on the victim line; (ii) a second crossing pulse of the opposite polarity on each aggressor line concurrent with the first crossing pulse on the victim line; and (iii) a reflection in the opposite direction of the first transition of the first crossing pulse, wherein the reflection results from a previous transition on the victim line.

An adaptive alarm system is responsive to a physiological parameter so as to generate an alarm threshold that adapts to baseline drift in the parameter and reduce false alarms without a corresponding increase in missed true alarms. The adaptive alarm system has a parameter derived from a physiological measurement system using a sensor in communication with a living being. A baseline processor calculates a parameter baseline from a parameter trend. Parameter limits specify an allowable range of the parameter. An adaptive threshold processor calculates an adaptive threshold from the parameter baseline and the parameter limits. An alarm generator is responsive to the parameter and the adaptive threshold so as to trigger an alarm indicative of the parameter crossing the adaptive threshold. The adaptive threshold is responsive to the parameter baseline so as to increase in value as the parameter baseline drifts to a higher parameter value and to decrease in value as the parameter baseline drifts to a lower parameter value.
