A haptic drive circuit for an electrical muscle stimulation electrode has an input for receiving a haptic signal based on a haptic effect from a haptic effects processor. The microprocessor disables or locks the wireless device if the measurement by the detector of the strength of the signal transmitted by the wireless transmitter is less than a predetermined value, thereby indicating that there is more than a predetermined separation distance between the protected device and the transmitter, i. The inner race includes a radially inner surface having a plurality of axially extending splines. The memory subsystem includes a separate TLB for stream prefetches; or a joint TLB backing the stream prefetch TLB and loadstore TLB; or a separate TLB for each prefetch engine. A fourth switch is coupled between second and fourth nodes in the H-bridge. These 1H-imidazole derivatives are potent cannabinoid-CB1 receptor agonists, partial agonists or antagonists, useful for the treatment of psychiatric and neurological disorders, as well as and other diseases involving cannabinoid neurotransmission.
