An electronic system includes a reader and a remotely powered and remotely interrogated sensor transponder. The sensor transponder includes a coil or an antenna, a switched reactance circuit, a processor, and a sensor. The sensor transponder receives power radiated from the reader to the coil or antenna. The sensor uses the power for sensing. The sensor transponder is capable of processing sensor data in the processor and transmitting the sensor data to the reader using the switched reactance circuit. In one embodiment, the receiver coil or antenna is part of a resonant tank circuit which includes an impedance matching circuit. The impedance matching circuit is connected to the receiver coil or antenna to provide greater current to the sensor or other power-using device than would be available to the sensor or other power-using device if the sensor or other power-using device were connected between the first and second end. The impedance matching circuit can be two or more taps to the coil or antenna.

A real-time digital cytometer on a chip system utilizing a custom near field CMOS active pixel intelligent sensor that is flip-chip attached to a fluidic microchannel etched in a thin glass substrate. The CMOS active pixel sensor, fabricated using a 0.18 micron process, is a mixed signal chip comprising a sixteen pixel linear adaptive spatial filter coupled to a digital serial interface.

Disclosed are systems, devices, and methodologies that facilitate increasing the effective fill-factor of digital sensors. In general, fill-factor relates to the active area or photosensor region of the sensor with respect to the inactive area/deadzone or space between pixels. By increasing the effective fill-factor, transmission of optical information is increased to the sensor while mitigating information loss between pixels. A digital camera may contain a sensor that is responsive to electromagnetic radiation and a coherent scattering medium between the sensor and a lens that diffuses the electromagnetic radiation with respect to the sensor in order to increase the effective fill-factor.

A wireless sensor and actuator network includes a number of wireless nodes, each of which may be connected to any one or combination of analog sensors, digital sensors, and actuators, and is powered by an autonomous power supply such as a battery or solar panel. Since autonomous power sources may not have sufficient voltage for powering many types of analog sensors, digital sensors, and actuators, power management techniques are used in the node and in the autonomous power supply as needed to enable effective and long life operation of the node and connected devices. These power management techniques include the use of a low impedance energy reservoir and a variable voltage boost converter whose output voltage magnitude, duration, and operating times are software configurable and controllable. The power management techniques are particularly useful for operating a wide range of different types of sensors and actuators.
