Abstract: A method and related system for monitoring a time-temperature profile comprises measuring by a temperature sensor a temperature of an object, recording by an electronic device a time-temperature data point including the temperature and a time at which the temperature was measured, communicating the recorded time-temperature data point by the electronic device to a computing system, and determining by the computing system whether the recorded time-temperature data point is outside a predetermined acceptable range.

Abstract: A flexible fuel sensor for measuring the fuel level in a tank in which the sensor is installed. The flexible fuel sensor comprises a fitting arranged to be mounted to a mated fitting on a fuel tank associated with a hole in the fuel tank, a flexible down member extending from the fitting in a first direction and including a fuel level sensing mechanism, the down member configured to be mounted to extend through the hole into the fuel tank, and a sensor head extending from the fitting in a second direction and including sensor electronics coupled to the fuel level sensing mechanism. The flexible down member may comprise a coil made of steel wire.

Abstract: One or more sensors mounted on a railcar sense the effect of weight of the railcar and transmit the data, for example via a communication link, to a user for storage and feedback where needed. In one embodiment the sensors are mounted on one or more rail trucks that carry the car body.

Abstract: A mobile refrigerator unit is operated remotely via wireless technology using a system with a local maintenance switch. A local override switch turns the refrigerator unit on and off, but keeps it on in the event of failure of the maintenance switch.

Abstract: An antenna switch is provided, comprising: an antenna cable connector that connects to a radio RF output port that both receives an RF signal at a receive frequency, and transmits an RF signal at a transmit frequency that differs from the receive frequency; an RF switch having a common contact that is switchable between a receive antenna contact and a transmit antenna contact; a level comparator comprising an input connected to the antenna cable that: when a voltage at the input is below a predefined threshold value, causes the RF switch to contact the receive antenna; and when the voltage at the input is above a predefined threshold value, causes the RF switch to contact the transmit antenna.

Abstract: To test whether a trailer is coupled to a tractor when the tractor ignition switch is off, a test switch in the trailer connects a high-impedance power source in a trailer to a line carrying energy from the tractor ignition switch to the trailer's electrical load, and measures the voltage at the line. A high voltage indicates a connection only to the electrical load in the trailer and thus a decouple. A low voltage indicates a measurement of the electrical loads in both trailer and tractor and hence a coupling.

Abstract: A method and apparatus are provided for determining a level of fuel in a tank, comprising determining a dielectric constant of fuel in a tank; measuring a capacitance of an unknown depth of the fuel in the tank; and calculating the depth using the dielectric constant and the capacitance. Embodiments of the apparatus utilize a capacitor plate submerged in the fuel to determine the dielectric constant of the fuel, and then use a plate of a separate capacitor to determine the fuel level, once the dielectric constant is known.

Abstract: An automated and/or remote method for identifying and/or changing the source of power for these generator sets, which may apply to any environment where there are alternative sources of power available which must be managed remotely (such as for other powered containers not used for refrigeration transport).
