Abstract: Systems and methods for controlling belt speed are provided. In one embodiment, a control system includes a driving mechanism configured to move a belt in a longitudinal direction, the belt having support portions separated from each other by gaps. The control system includes a sensing apparatus configured to optically detect the presence of the support portions and gaps when the belt is moved in the longitudinal direction. A processing device is configured to receive a detection signal from the sensing apparatus that is indicative of the presence of the support portions and gaps. The processing device is further configured to monitor belt speed based on a number of gaps detected over a predetermined amount of time. A controller is configured to receive control signals from the processing device and control the operation of the driving mechanism based on the number of gaps detected over the predetermined amount of time.

Abstract: A quick release pillow block bearing assembly has end pieces, a center bearing housing carrying a bearing, and quick release pins for retaining the bearing housing with the end pieces. The invention enables replacement and or repair of the bearing and its counterparts easily, efficiently, and less often. The user need only remove the quick release pins remove the bearing housing and thereby gain access to the housing, which also provides access to the bearing/shaft and counterparts. Upon removal of the quick release pins, the center housing may be removed from the structure, while the end pieces stay in place, allowing one to remove and install the bearing quickly. It also enables removal of the shaft in seconds, thus permitting easy and quick replacement of worn sections of the bearing.

Abstract: An autonomous path treatment system and associated path treatment method uses a mobile path recording device having a locator, a processor and firmware to capture a sequence of coordinates and directions of travel of a path as the mobile device is moved along the path and generate a path program file. The system also has an autonomous path treatment robot having: a treatment mechanism for treating the path; a controller having a processor and memory storing firmware that when executed obeys steps of the path program file to control the motor and the treatment mechanism to treat the path; and a server configured to execute a path program to process the captured sequence of coordinates and directions into the path program file containing instructions for controlling the autonomous path treatment robot to treat the path based upon the coordinates.

Abstract: A quick release roller for a conveyor system is configured to permit easy maintenance and replacement of the rollers in the system. The roller includes first and second roller segments that may be cooperatively joined together around a mounting shaft carried by the conveyor. The segmented roller permits the quick release to be removed and attached to the conveyor without disassembly of other conveyor components supporting the roller. The quick release roller facilitates maintenance and service of the conveyor system while limiting operational downtime for the conveyor while being serviced.

Abstract: A radio frequency locator system and method. First, second and third reference devices are operable to transmit a plurality of spread spectrum chirp signals frequency offset from one another. An object device is operable to receive the plurality of spread spectrum chirp signals, the object device is further operable to evaluate the received plurality of spread spectrum chirp signals for relative phase shifts between the plurality of spread spectrum chirp signals and derive a fine propagation time between the reference devices and the object device using the phase shifts between the spread spectrum chirp signals. The reference devices determine their location independent of the object device and determine the location of the object device as a function of each of their locations and of their range to the object device.

For example, there is provided a method that can include detecting a desaturation condition in an IGBT and initiating a turn off procedure when desaturation is detected. The turn off procedure can include holding a gate of the IGBT at at least one voltage level intermediate between a positive rail voltage and a negative rail voltage of an operational range of the IGBT.
