A front loading refuse vehicle includes at least one positive displacement pump having an associated valve system in fluid communication with drive mechanism that operates a lifting arm, packer, a rear door of the vehicle, and a hoist for a refuse storage body. In one example, a head-mounted computing system includes a see-through display configured to present an augmented reality image in front of an environment when viewed through the see-through display, a logic subsystem, and a storage subsystem. Further described is a method for easier releasing soil from textiles in laundry processes and a detergent containing said block copolymers. This method allows more than one decoder to decode the same bitstream giving different resolutions depending on the computational capability of the decoder. The system may include a first client network device having a first client module and a second client network device of the plurality of client network devices where the second client network device includes a Dual Access Point and Station enabled device. Multiple panels for processing can be realised, with lower panels being processed before upper panels, by excavating a sub-level to separate the lower and upper panels.
