Abstract: An analytical instrument having a sensing system, a stage adapted to receive a sample carrier, a motion actuator assembly for positioning the sensing system and/or the stage, a temperature control element, and a signal processing module are disclosed. Methods of analyzing cell samples with the analytical instrument are also disclosed.

Abstract: A control system for preventing vehicle collisions may include a vehicle location determination module, a terrain determination module, a terrain surface coefficient of friction estimation module, and a sensing system configured to generate signals indicative of vehicle speed, vehicle pose, vehicle size, vehicle weight, vehicle tire type, vehicle load, vehicle gear ratio, weather characteristics, and road conditions for a vehicle operating at a job site. A manned vehicle trajectory determination module may receive location information and plot a first travel path for a manned vehicle based at least in part on a location, heading, and speed of the manned vehicle and a desired destination for the manned vehicle.

Abstract: A method for indirectly detecting a movement of a machine and a failure of a speed sensor is disclosed. The method may include receiving an operator input signal, and determining a first factor based on the operator input signal. The method may also include measuring a machine operation parameter, and determining a second factor based on the machine operation parameter. The method may further include identifying a movement of the machine if the first factor is out of a first threshold range and the second factor is out of a second threshold range for at least a first threshold length of time. The method may also include determining a speed sensor failure if the movement of the machine is identified and no speed is detected by the speed sensor for at least a second threshold length of time.
