Abstract: Example embodiments relate to techniques for hardware-in-the-loop testing with continuous integration for radar testing and development. A computing device may receive a target output for radar operation parameters undergoing development tests and determine whether a first output produced by a field programmable gate array (FPGA) based on the radar operation parameters differs from the target output less than a first threshold difference. When the output from the FPGA passes the comparison, the computing device may then cause a radar unit to transmit radar signals toward a target according to the radar operation parameters, which produces a second output that can also be compared to the target output. The FPGA may process signals for the radar unit. In some cases when the second output differs from the target output less than a second threshold difference, the computing device may provide the radar operation parameters as a radar software update to vehicles.

Abstract: An insertless perforated mill roll body adapted to be detachably sleeved upon a roller shaft for the grinding of a fluid-containing material such as sugar cane and extracting fluid such as sucrose juice therefrom. The insertless perforated mill roll body comprises a plurality of shish-ke-bab-like fluid channel strings to be encased in the roll body, each fluid channel string comprises a hollow fluid channel preferably defined by a channel wall member which generally extends between the two axial ends of the roll body with a plurality of fluid passage members affixed thereto. The roll body is formed by casting a castable material such as cast iron or steel to enclose the fluid channel strings, whereupon a hollow center bore is provided to receive the shaft therethrough. Each fluid passage member contains at least one generally radially extending fluid passage to allow communication between the outer periphery of the mill roll body and the fluid channel.
