A sensing method and device for sensing the position of an object are provided. The sensing device comprises a light source for generating a plane light, and a sensor unit disposed at one side of the light source. The sensing method comprises driving the light source to generate the plane light, forming a reflective light distribution by the object reflecting the plane light; and estimating a relative distance between the object and the light source according to the reflective light distribution.

Systems and methods are provided for measuring articles contained within and/or dispensed from a receptacle. The present invention incorporates a counter device that measures the displacement of a conductive target relative to an LC circuit using an inductance-to-digital converter. In operation, a change in weight of articles in a receptacle will displace or deform a conductive target relative to the position of the LC circuit and, as such, it will create a measurable differential relating to inductance. Based on the measured differential, the number of articles (e.g., pills) within and/or taken from the receptacle is determined using a processor. In accordance with a further aspect, the counter is configured to compensate for a temperature-dependent variation in the measured electrical parameter algorithmically using the processor and/or through the particular configuration of the receptacle components.

The present invention relates to a position compensation device using visible light communication and a method thereof. To this end, the present invention receives a visible light signal which includes lighting position information from a lighting device to extract the lighting position information from the received visible light signal, and calculates a compensated position of a position compensation device by using the extracted lighting position information if a request for position compensation exists, thereby providing an exact position of a user indoors.

A measurement apparatus detects a person and an umbrella based on acquired image data, and measures the number of persons based on a detected result.

A device for determining an occupancy rate of a conveying means is provided. The device comprises an adjusting means for adjusting at least one detecting means such that the at least one detecting means detects, after detecting the freight conveyed by the conveying means, the conveying means without conveyed freight, or such that the at least one detecting means detects, after detecting the conveying means without conveyed freight, the freight conveyed by the conveying means, and a determining means for determining a current occupancy rate of the conveying means on the basis of the position of the at least one detecting means, which was adjusted by the adjusting means.

An autofocus imaging system for a microscope system includes a tilted autofocus image sensor that images an oblique cross-section of a slide. The autofocus imaging system focuses multiple sequential overlapping images, which have been taken by the tilted autofocus image sensor, by making a comparison of the multiple sequential overlapping images. An axial position of a tissue layer on the slide can be determined from a polar error signal resulting from this comparison.

Optoelectronic devices (e.g., optical proximity sensors), methods for fabricating optoelectronic devices, and systems including optoelectronic devices, are described herein. An optoelectronic device includes a light detector die that includes a light detector sensor area. A light source die is attached to a portion of the light detector die that does not include the light detector sensor area. An opaque barrier is formed between the light detector sensor area and the light source die, and a light transmissive material encapsulates the light detector sensor area and the light source die. Rather than requiring a separate base substrate (e.g., a PCB substrate) to which are connected a light source die and a light detector die, the light source die is connected to the light detector die, such that the light detector die acts as the base for the finished optoelectronic device. This provides for cost reductions and reduces the total package footprint.
