A digital sensor is an electronic or electrochemical sensor, where data is digitally converted and transmitted. Sensors are often used for analytical measurements, e.g. the measurement of chemical and physical properties of liquids. Typical measured parameters are pH value, conductivity, oxygen, redox potentials, and others. Such measurements are used in the industrialized world and give vital input for process control.
Remotely powered and remotely interrogated wireless digital sensor telemetry system
ActiveUS7256695B2More powerElectric signal transmission systemsElectrotherapyElectronic systemsPower flow
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.

Medical probe with reduced number of temperature sensor wires
InactiveUS6979329B2Little and no noiseReduce in quantityThermometers using electric/magnetic elementsCatheterBody tissueDigital switching
Systems and methods for reducing the number of temperature measurement wires in multiple temperature sensor ablation systems are described. In a preferred embodiment, temperature sensors capable of measuring the temperature of body tissue and transmitting the temperature data digitally are incorporated in a catheter or probe ablation system that also includes electrodes in operative contact with the sensors. The sensors are connected in parallel to a common electrical bus, thereby allowing the system to operate using a reduced number of electrical paths as compared to conventional ablation systems. The present invention is also directed to ablation systems that incorporate analog sensors rather than digital sensors. In this embodiment, the system utilizes digital switching, filtering circuits, or oscillators to reduce the number of wires required to operate the sensors.

Color interpolation using data dependent triangulation
ActiveUS7305148B2Quality improvementFunction increaseGeometric image transformationCharacter and pattern recognitionAnti-aliasingTriangulation
A fast method of color interpolation of pixels of an image acquired by a color filtered digital sensor uses a very simple cost function that nevertheless produce interpolated images of good quality. The cost function is computationally simpler because it does not require the calculation of powers and square roots. The triangulation algorithm may be executed in far less time, while practically ensuring the same performance. The triangulation algorithm on average may use only two iteration steps. The interpolation process may be followed by an anti-aliasing processing that effectively removes color artifacts.

InactiveUS20060244851A1Improve fill factorKeep resolutionTelevision system detailsTelevision system scanning detailsFill factorElectromagnetic radiation
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.
