An auxiliary hydraulic system for vehicles, in particular pick-up trucks, is configured to supply hydraulic fluid under pressure to both on-board and off-board auxiliary equipment such as snow plows, dump boxes and wood splitters. The exemplary flexible network simulator can establish different connectivity protocols between multiple electronic devices and test the electronic devices using customized sets of network conditions. The microwave chamber comprises a permeable top and wave guides around the perimeter through which microwaves can be introduced into the device using magnetrons. The output is created either after the processing step, where the output is created in accordance with the control instructions decoded from the control image, or prior to the processing of the control instruction. A plurality of cavities are formed in the encapsulant to expose the corresponding ball placing regions to resolve the solderability of the solder balls and to enhance the stability and reliability of wire bonding and solder ball placing. Selected interconnecting optical fibers include controllable wavelength-selective elements, such as magnetically controllable fiber gratings, which are capable of transmitting or reflecting individual channels within the multi-wavelength optical signals so that a selected channel of a particular wavelength can be routed from any of the input ports to any of the output ports of the switch.
