Novel compounds of the structural formula are antagonists andor inverse agonists of the Cannabinoid-1 receptor and are useful in the treatment, prevention and suppression of diseases mediated by the CB1 receptor. The system includes a power transmitter configured to transmit power via a wireless coupling to the mobile devices. The verifying entity may determine from the version of the credential and the digital signature whether the credential originated from a trusted issuing entity. A first system recovers solvent or solution from the object being processed and chamber, and a second system, separate from the first system, further recovers residual solvent or solution from the object and chamber. The ductile binder phase, a cobalt-manganese alloy, is used in appropriate quantities to tailor good hardness and reasonable fracture toughness for hard materials so they can be used suitably in industrial machining and grinding applications.
