Abstract: Techniques are provided to estimate the location of an RFID tag using tag read information, such as a tag read count or a tag read rate, and an opportunity metric, such as an inventory cycle duration, inventory cycle rate, or inventory cycle count. A tag tracking system determines read information for a tag in a zone and an opportunity metric associated with the tag and the zone. The tag tracking system then computes a success rate based on the tag read information and opportunity metric, and uses the success rate to estimate the location of the tag.

Abstract: A method for detecting cavitation in a hydrostatic system includes capturing an oscillation typical for the cavitation from a pressure captured over time. Furthermore, the method includes establishing an evaluation variable for cavitation on the basis of the captured oscillation. Additionally, the method includes comparing the evaluation variable to a comparison value.

Abstract: A power split transmission includes a first power branch having a continuously variable transmission and a separable second power branch. The two power branches are combined again in a summation gear and a device connects or disconnects the second branch when a synchronous condition is present when changing from an initial driving range into a target driving range. A control device for controlling and adjusting the transmission ratio of the first power branch is connected to the continuously variable transmission. A predicting device for predicting an efficiency ?v of the first power branch in a target driving range is connected to the control device.

Abstract: RFID readers, systems, and methods are provided for overcoming the effects of RF interference. While a system is communicating in a channel, RF interference is monitored. If it is low, then the next channel to be hopped onto is chosen in an unbiased manner. But if interference is high, then the next channel to be hopped onto is chosen in a biased manner that disfavors at least one channel over another, in view of the detected interference. The choice of the next channel can thus result in diminishing communication in channels with a lot of RF interference.

Abstract: RFID readers, systems, and methods are provided for overcoming the effects of RF interference. While a system is communicating in a channel, RF interference is monitored. If it is low, then hopping to another channel is performed according to an ordinary decision. But if interference is high, then hopping out to another channel can be earlier than would be dictated by the ordinary decision under the same circumstances. The earlier hopping out can result in diminishing communication in channels with a lot of RF interference.
