An efficient synthesis for the preparation of N–6–2-oxo-1-azepan-3-yl-4-piperidine-1 -carboxamide, by coupling -3-amino-6–1-azepan-2-one and 2-oxo-1–2,3-dihydro-1H-imidazo4,5-bpyridine dihydrochloride with 1,1\u2032-carbonyldiimidazole as carbonyl source; and an efficient preparation of the potassium salt of N–6–2-oxo-1-azepan-3-yl-4-piperidine-1-carboxamide. The system includes a seat belt associated with a seat of a vehicle and a shoulder belt portion of the seat belt comprising a shoulder stabilizing zone and a thorax belt portion, wherein the shoulder stabilizing zone includes a larger width dimension than the thorax belt portion. The partial discharge detection test link is a permanent or temporary substitute for a conventional service link, connects directly across the power cable accessory and includes a conductor member and a partial discharge sensor. The heat from the capillary can be efficiently dissipated via the electrode, and also the temperature increase in the capillary can be prevented. A jet outlet is arranged to direct a jet of fluid across that side of the screen on which such matter would otherwise tend to collect when the apparatus is in use. Each of the EMA motoring subsystems includes: an EMA; at least one motor for driving the EMA; and power controls for operating the motor, wherein the power controls includes a DSP controller for sampling and processing data at low-frequency sampling rates.
