"If we can increase the number of genes implicated in blood pressure maintenance from the current 12 to the expected 50 in the next year, our understanding of the biology will change completely," he added.
Each product offers a specific consumer health benefit--resVida for healthy ageing, geniVida to improve bone health and help reduce menopausal symptoms, tensVida for healthy blood pressure maintenance and insuVida for blood glucose management.
Addressing functionality, the Engineered Solutions Team identified valve hysteresis as the key to improved response time and, consequently, critical pressure maintenance. Utilizing 310 valves, Humphrey was able to provide the customer with a fast-acting valve that met the requirements for a low leak rate and responsiveness down to [+ or -] 3 psi.
Downsized, the system uses a newly developed mechanism to autonomously intermittently run to drastically lower power consumption during pressure maintenance time, which accounts for 90% of the overall operation time.
