摘要： An integrated gesture sensor module includes an optical sensor die, an application-specific integrated circuit (ASIC) die, and an optical emitter die disposed in a single package. The optical sensor die and ASIC die can be disposed in a first cavity of the package, and the optical emitter die can be disposed in a second cavity of the package. The second cavity can be conical or step-shaped so that the opening defining the cavity increases with distance from the upper surface of the optical emitter die. The upper surface of the optical emitter die may be higher than the upper surface of the optical sensor die. An optical barrier positioned between the first and second cavities can include a portion of a pre-molded, laminate, or ceramic package, molding compound, and/or metallized vias.

摘要： A method for aligning an opto-electronic component in an IC die with an optical port is disclosed. This is achieved, in various embodiments, by forming alignment features in the IC die that can mate with complementary alignment features of the optical port. The formation of alignment features can be performed at the wafer level during fabrication of the IC die. An optical signal carrier may be optically coupled to the optical port such that the signal carrier may communicate optically with the opto-electronic component.

摘要： An electrical circuit includes a sensor configured to generate a current signal comprising a first portion comprising a contribution from a target source and/or a second portion comprising a contribution from sources other than the target source, a trans-impedance amplifier that amplifies the current signal and generate a low noise signal, and a high pass filter that converts the low noise signal into an AC signal having a positive amplitude, a negative amplitude, and a zero cross-over point between the positive and negative amplitudes. The circuit also includes a positive integrating amplifier that receives the positive amplitude of the AC signal and generates a positive integrated value over an integration period, and a negative integrating amplifier that receives the negative amplitude of the AC signal and generates a negative integrated value over the integration period. The circuit further includes at least one analog-to-digital converter that receives the integrated values.

摘要： Embodiments of the present disclosure provide code readers for reading codes provided as patterns imprinted on objects. Light interacts with a pattern by e.g. being reflected from or transmitted through the pattern, and at least some of the light that has interacted with the pattern is incident on photosensitive element(s) of one or more photodetectors of a code reader. The code reader employs centroid-measuring photodetector(s), i.e. photodetectors that detect light in such a manner that centroid of a pattern can be obtained directly from the photocurrents generated as a result of the photosensitive elements detecting light incident thereon. The code reader is then configured to process the detected light to determine a centroid of the pattern from the detected light and to decode data encoded in the pattern based on a position of the centroid. Such code readers are substantially less complex than camera-based devices and avoid mechanical scanning.

摘要： A current detection module capable of differentiating and quantifying contribution to a current signal generated by a sensor in response to stimulation by a certain target source from contributions from sources other than the target source (ambient sources) is disclosed. As long as the contribution from the target source comprises a pulsed signal, the module may synchronize itself to the pulse(s) so that there is a predetermined phase relationship between the pulse(s) and functions carried out by various stages of the module. The module may be re-used to also detect and quantify contributions from ambient sources by presenting these contributions to the module as pulses that trigger synchronization of the module. To that end, a detection system disclosed herein is based on the use of such current detection module and allows mode switching where, depending on the selected mode of operation, the module is configured to perform different measurements.

摘要： An optical detector may include an epitaxial layer having a continuous surface provided on a surface of a substrate. Two or more electrodes may be arranged at different positions in the epitaxial layer so that the electron-hole pairs generated in the epitaxial layer from incident light passing through the aperture and reaching the epitaxial layer have a varying probability of being collected by each of the electrodes as the angle of the incident light changes. The electrodes may be arranged at different depths in the epitaxial layer. The epitaxial layer may be continuous and have a continuous aperture-facing surface between each of the electrodes associated with a particular aperture to ensure that more light passing through the aperture is absorbable in the epitaxial layer and subsequently detectable by the electrodes. This may result in improved light detection capabilities.

摘要： Device for improving an optical detecting smoke apparatus and implementing thereof. Apparatus and methods for detecting the presence of smoke in a small, long-lasting smoke detector are disclosed. Specifically, the present disclosure shows how to build one or more optimized blocking members in a smoke detector to augment signal to noise ratio. This is performed while keeping the reflections from the housing structure to a very low value while satisfying all the other peripheral needs of fast response to smoke and preventing ambient light. This allows very small measurements of light scattering of the smoke particles to be reliable in a device resistant to the negative effects of dust. In particular, geometrical optical elements, e.g., cap and optical defection elements, are disclosed.
