Abstract: Methods relating to device level performance monitoring and analysis include accessing device data including a listing of network devices, with each network device having a device profile. The methods further include accessing service reports, with each report related to a service issue. A set of devices profiles from the listing of network devices may be identified based on a particular device being associated with a particular service issue. The method further includes determining a set of problem prone device profiles from the set of devices profiles. A system including at least one database and a report processor may be configured to associate device data with service reports, identify service issue trends from service reports, identify at least one at risk device susceptible to future service issues related to service issue trends, and provide preventative support to the identified at least one at risk device.

Abstract: Methods relating to the generation of service level agreement (SLA) performance report include measuring, over a service period, at least one service level measurement related to a provision of service. A measurable SLA commitment may include service level goals, with each goal containing a performance criterion, a target, and a comparison technique. A performance report may be generated based on the measurable SLA commitment and the at least one service level measurement and may include a goal analysis for each service level goal of the measurable SLA commitment. A system including a database and a report processor may be configured to generating a performance report including determining an actual level of service provided, comparing the measurable SLA commitment to the actual level of service provided, and determining a missed goal based on the actual level of service provided not realizing the SLA goal.

Abstract: A method of communicating information between a host device and a potentially portable module device which measures thermal accumulation over time via a temperature controlled counter. The temperature controlled counter may operate using substantially Arrhenius' law. The host device communicates with the portable module via a single wire bidirectional data bus. The single wire bus and one-wire communication protocol allows data flow between a host and a plurality of devices connected to the single wire bus. The single wire bus allows for a great versatility of uses for the portable module.

Abstract: A system architecture which provides efficient data communication, over a one-wire bus, with a portable data module which does not necessarily include any accurate time base whatsoever. The time base in the module can be extremely crude (e.g. more than 4:1 uncertainty). An open-collector architecture is used, with electrical relations defined to absolutely minimize the drain on the portable module's battery. The protocol has been specified so that the module never sources current to the data line, but only sinks current. The protocol includes signals for read; write-zero; write-one; and reset. Each one-bit transaction is initiated by a falling edge from the host. The time base in the module defines a delay, after which (in write mode) the module tests the data state of the data line. In read mode, after a falling edge the module does or does not turn on its pull-down transistor, depending on the data value.

Abstract: A secured metal token using a single wire communication system is employed to dispense units of value and to provide a secure storage device for controlling the dispensing of articles or service items. The metal token can be formed of two pieces with a simplified electronic circuit inside which can contain units of value for the dispensing of items using the memory within the metal token as a secure vault. The token uses a simple two wire (ground and combined clock/data) arrangment. As goods are purchased or services rendered the value of those good or services is deducted from a prestored amount within the token.

Abstract: A communication circuit is provided in which reads from a device are controlled by sensing a transition by a host communicating with a device. The device then accepts a one which holds the line high for a predetermined time period or accepts a zero when the line is held high for a different time period. The sending of data is accomplished in a symmetrical relationship by having the device after the host pulls the line high by either by allowing the line to remain high or forcing the line to ground within the requisite time periods. This allows the "slave" device to consume almost no power in either the read or the write modes.

Abstract: A portable electronic data module for secure transactions, the electronic data module having a random number generator and an optimized co-processor for producing unbreakable key sets for a two-key cryptosystem. A real-time clock is sampled depending upon an external random event series such as power-ups of the data module by a host apparatus, and based upon the contents of the sample thus obtained, the entropy of a previously-loaded accumulator is further enhanced to achieve a pool of true random numbers. By repeatedly requesting random bytes of information from said pool of random numbers, large random numbers are created which are then rendered prime and used for key set creation.
