Abstract: The invention aims at downsizing a sensor node incorporating a biosensor to detect biological information and at improving the accuracy of detection made by the biosensor and ensures a quality of communication performed by the sensor node. In the sensor node, a sensor section with a pulse wave sensor formed therein and a main body section with a data processing unit and a wireless communication unit formed therein are separated. The sensor section includes an A/D converter unit that converts an analog signal corresponding to biological information detected by the pulse wave sensor to a digital signal. Digital signal transmission is performed from the A/D converter unit to the data processing unit. Moreover, in the sensor node, there is no conductive member that planarly overlaps with an antenna.

Abstract: An apparatus is described that includes an image sensor having timing and control circuitry and threshold circuitry. The timing and control circuitry is to generate signals to cause multiple transfers of charge from a photo-diode to a storage capacitor within a pixel cell during an image capture sequence. The threshold circuitry is to track the storage capacitor's voltage over the course of the multiple transfers and recognize when the storage capacitor's voltage reaches a threshold.

Abstract: A composition, a method fabricating the infrared ray transmitting filter, and an infrared ray sensor are provided. When the composition forms a film with a thickness of 1 μm, transmittance of the film in a wavelength in a range from 400 nm to 700 nm is less than 4%, and transmittance of the film in a wavelength in a range from 900 nm to 1300 nm is more than 90%. The composition comprises an alkali-soluble resin at least containing an acrylic group, a carboxyl group, and a fluorene ring, a photoinitiator, an unsaturated monomer, a pigment mixture, and a solvent. The pigment mixture is formed by mixing a colorant dispersion and a pigment in a weight ratio from 60:40 to 70:30.

Abstract: Presented here are devices and methods to correct ambient light measurements made in the presence of optical elements, such as the curved edge of the cover glass associated with the mobile device. In one embodiment, a film with optical properties is placed within the ambient light sensor to diffuse the high-intensity light beam coming from the optical element. In another embodiment, an aperture associated with the ambient light sensor is disposed to prevent the high-intensity light beam from entering the ambient light sensor. In another embodiment, a processor coupled to the ambient light sensor smooths the peak associated with the high intensity light beam produced by the optical element.

Abstract: One embodiment of the disclosure includes an A-D conversion circuit connected to a photodiode for providing a silicon photomultiplier that with enhanced detection accuracy and a time resolution. A current generated upon photon detection by the photodiode partially flows into another photodiode adjacent to the photodiode arranged in parallel via a resistor. At this time, the current is charged into a parasitic capacitance adjacent to the photodiode, and thereafter is discharged. However, the discharged current cannot flow toward an output terminal by the A-D conversion circuit, and also cannot switch the A-D conversion circuit. Consequently, the construction of the disclosure can detect light with no influence of the current discharged from the parasitic capacitance. As a result, the disclosure achieves a silicon photomultiplier with high detection accuracy and a satisfactory time resolution.
