In a method of synchronizing with a separated disk cache, the separated cache is configured to transfer cache data to a staging area of a storage device. 1 to 20 mol % of the EXM copolymer and is a 4-vinylphenyl ester, preferably 4-acetoxystyrene; M is from 0 to 40 mol % of the EXM copolymer and is one or more ethylenically unsaturated monomers; and E is ethylene. To aid this optical interrogation, the display surfaces may be generally orthogonal to the disparate interrogating components. When the sensed temperature value is higher than the preset temperature value, the microprocessor controls the indication device not to operate and controls the heating unit stop heating the electronic components. Secured to the mast distal from the connector is at least one strap attachable to the dog’s collar or harness. In another embodiment, where selected frequencies are distributed in octave steps, the impedance spectrum can be determined using a captured time record that is reduced to a half-period of the lowest frequency.
