The present invention comprises a system for viewing measurements remotely, including a first processor that is connected to a wireless communications device; a sensor; and at least one measurement device comprising a second processor programmed to (1) receive an input from the sensor and (2) wirelessly communicate with the first processor. The first processor is programmed to retrieve measurements from the measurement device via the wireless communications device.

Wireless measurement device

A data link tester comprises a computer capable of a connection with a communications bus in a piece of equipment having at least one component in selective contact with the bus. The computer contains instructions for (1) building a roster comprising at least one identifier of the component and (2) then performing a diagnostic step comprising at least one of (i) analyzing communications received from the communications bus to determine the condition of communications with respect to the component, (ii) determining whether a message that contains the identifier has been received from the communications bus within a specified period of time, and (iii) diagnosing at least one fault condition in CAN communications in the communications bus by performing at least one CAN message check comprising determining whether a CAN message has been received from the communications bus and then performing at least one second diagnostic step. In some embodiments, the piece of equipment is a vehicle.

Data link tester

A virtual device driver for processing serial communications in a protected operating system. The virtual device driver adds a time-stamp to each character received at Ring-zero level of the operating system architecture. The time-stamp value is compared to a predetermined maximum acceptable time interval to determine if a valid packet was received.

Virtual device driver

An integral gear life monitor system and method for determining gear use and damage is disclosed. The system includes a first and second sensors for measuring the rotational speed and torque of a driveline component, such as an input shaft of a vehicle transmission, for a particular gear ratio at one or more time intervals over a period of time. Each time interval may be in the range of 40 ms to 100 ms. The period of time may be hours, days, month, or even years. A processor performs a statistical summation technique to transform the signals from the first and second sensors into an equivalent amount time for the particular gear ratio during that period of time. A driveline vibration analyzer can perform an online determination of the torsional vibrations for the particular gear ratio to determine whether vibration is a root cause of why a gear ratio is worn or damaged. The transformed signals can be stored in a non-volatile memory of the processor for later retrieval as a diagnostic tool to statistically measure the amount of life used by each gear ratio, to determine if a gear ratio is worn or damaged, to determine the root cause of why a gear ratio is worn or damaged, and to take proactive and/or reactive measures to extend the life of the transmission.

Transmission gear life monitor system

A convertible transmission system for a vehicle having an input shaft for connection to an engine and an output shaft for delivering rotational power to at least one axle. The transmission has a plurality of available gear ratios resulting in a maximum number of available gear ratios. In addition, a programmable controller is provided for selectively controlling the transmission to operate in a first operating configuration utilizing a first predetermined number of the available gear ratios that is less than the maximum number of available gear ratios. Moreover, the programmable control can have additional transmission configurations by selectively modifying certain operating characteristics, including for example, available gear ratios, desired operating gear ratios, maximum torque limits, shift points, default starting gear ratio, data relating to a predetermined shift strategy, a coast down gear ratio, shift delay timing, and/or skip shifting.

Convertible transmission system

A logistic service system includes a programmable vehicle module, a service computer, a central server, a first data link connecting the module to the service computer and a second data link connecting the service computer to the central server. Component information retrieved from the module and stored on the server is used to service the module. The component may be subjected to diagnostics or updated with new parameters.
