For example, some hospitals have had their own engineers design a custom-made walker for ventilated patients that incorporates a walking frame on wheels, an intravenous pole, an oxygen basket and a platform to support a ventilator, all in a single device.
The resulting architecture aims at achieving optimal performance in terms of low-distortion and high power efficiency while still allowing a low-cost implementation: all the digital processing part integrated in a single device, for example, a low-complexity FPGA, plus off-chip components only for the power stage, made up of a MOS H-bridge and an LC filter but without any heat sink.
To find all of these virtues in a single device, you'll have to wait another year or two.
Then, unless your demand for tidiness requires that all of your services are integrated in a single device, rely on free apps that offer alternatives to the Garmin pay services.
In this work, we designed a modified TSRR with metamaterial property to obtain desirable negative permeability bands that help in accommodating all three frequency bands of interest in a single device.
In order to overcome the above-mentioned limitations our research group is currently working on the design and fabrication of "true" lab-on-chip systems that integrate in a single device all the analytical steps from the sample preparation to the detection without the need for bulky external components such as pumps, syringes, radiation sources or optical detection systems.
An all-metal NSTX-U is envisioned to make direct comparison between all high-Z wall operation and liquid lithium PFCs in a single device.
