A user of a virtual object or computer model uses a haptic interface device in the real world to manipulate a virtual tool in a virtual environment to interact and modify the virtual object. The chemical separation unit, the Raman sensor substrate, and the Raman scattering spectrometer unit are held in or mounted to the single device body. The modifier includes a flag option marker configured to attach a flag to data; a sequence adding unit configured to add a protocol specific number to a sequence number; and a sequence subtracting unit configured to subtract the protocol specific number from an acknowledgement number. An operating state of the controlled transistor is changed in response to the control signal. The second support structures can include an elastomeric device that is configured to adjust radially and urge the interface of the preform against the first support structure.
