An important concern of any low power, wireless system is power management. Customers continue to demand small products in applications that require longer battery life. Two primary ways to meet that demand is to increase the energy available and to create more power efficient designs. Telesensors understands that proper application of both techniques will provide customers with the best performance and lowest overall cost.
Energy Availability
Telesensors addresses energy availability by first applying the best and most appropriate battery technology for the application. Type of battery, voltage levels, discharge characteristics, system power draw, recharging requirements, and overall environmental condition are all important considerations in battery selection. Matching the right battery to the system needs can greatly enhance overall battery life.
To further increase the available energy, power or energy harvesting can be used. Mature energy harvesting techniques such as solar panels and small wind generators are often a good cost effective choice. Newer technologies that can harvest energy from vibration, ambient noise, changes in temperature, and other environmental sources are also good choices depending on the application. Telesensors can apply a variety of energy harvesting techniques to create the best solution.
Power Efficient Designs
Designing more power efficient electronics in battery operated systems is equally as important as increasing the available energy. Telesensors heritage in ASIC design provides a distinct advantage in developing very energy efficient electronics. Understanding which system components consume the most power and selecting the most power efficient options are the first steps in creating energy efficient designs. Applying low power techniques to power cycle and duty cycle of the components adds another level of energy savings. Data compression and efficient firmware can provide even more power savings.
The best energy/power management solution is rarely achieved using a single power management technique. Many applications require a multi-faceted approach to achieve the required battery life. As demands for more information from less power continues to increase, Telesensors is meeting the challenge by developing comprehensive strategies to solve our customer’s complex problems while providing the best overall value.
