An electrically operated smoking device configured to receive a smoking article is provided, including: a housing defining a cavity configured to at least partially receive the smoking article; and an image sensor configured to detect indicia on the smoking article, the image sensor being disposed on a periphery of the cavity and including a light source, an image detector, and a plurality of microlenses held in a support structure, the plurality of microlenses being configured to provide a mosaic of inverted images on the image detector. A smoking system is also provided.

A positioning system, in particular, six-dimensions positioning system of a shadow sensor with respect to a constellation of light sources is provided. The sensor can be a shadow sensor and has a mask and a 2D imager. By recording the shadow of the mask cast by each light source on the imager, and by properly multiplexing the light sources, the system can compute the 6D position of the shadow sensor with respect to the constellation of light sources. This computation is based, in part, on treating the shadow of the mask cast on the imager as the equivalent of the projection of light in a pinhole or projective camera. In one embodiment, the system is applied in a surgical domain. In another embodiment, the system is rapidly deployed.

Positioning system and method

A positioning system, in particular, positioning in six dimensions of a sensor with respect to an assembly composed of a multitude of LEDs, is provided. The sensor is a shadow sensor and has a mask and a 2D imager. By recording the shadow of the mask cast by each LED on the imager, and by properly multiplexing the LEDs, the system can compute the 6D position of the LED assembly with respect to the shadow sensor. This computation is based, in part, on treating the shadow of the mask cast on the imager as the equivalent of the projection of light in a pinhole camera.

A security device for the identification or authentication of valuable goods is described, including a thin material layer () presenting a stochastic pattern including micro/submicrostructures, where the latter are arranged in blobs () each of which presents a complexity factor where L is the perimeter of the blob and A its area, and wherein blobs having a Cvalue greater than or equal to 2 cover at least 5%, preferably at least 15%, of the device surface. According to a preferred embodiment, the material layer may include a film including at least a first and a second polymers arranged respectively within a first and a second phases defining the micro/submicrostructures. Preferred processes of fabrication are also disclosed, as well as a method for securing a valuable good based on such a security device.

A position measurement system for determining 2D displacement or position of a mobile element with respect to a reference frame, including: a point light; an optical mask having transparent and opaque areas defining a repetitive pattern on at least one side of its surfaces; an imager, fixed to a mobile element, including integrated electronic circuits allowing detection, computing and analyzing of a shadow projected by the optical mask. The position measurement system includes an optical diffuser plate between the light source and the mask. The imager, mask and diffuser plate form an assembly so as to produce a light spot created by the scattering of the incident light beam emitted by the light source on the diffuser plate. The mask positioned between the diffuser plate and imager, produces a shadow on the imager, allowing to compute and provide 2D position of the mobile element relative to the fixed reference frame.

Positioning device comprising a light beam

A system measures the position of a light source in space using an imager and transparent surface with a pattern on top. The pattern consists of a repetitive pattern and a distinctive element. The system achieves sub-micron precision. It also handles the measurement of several light sources simultaneously, and the measurement of the position of a retroreflector instead of the light.

Measurement system of a light source in space

A one-dimension position measurement system includes: a first ruler having a first one-dimension binary code sapplied thereon, a camera for acquiring a picture of a portion of the code s, the portion having a length of I bits, and some processing elements. Each codeword of length I of the one-dimension code sis unique within the whole code s. A codeword ais read from the acquired picture, and the processing elements are implemented for computing an absolute position p of the codeword aof the code sfrom: (I). An ad-hoc interpolation method is used to obtain a precision way below the distance between two bits of the codewords. The code smay be applied on the ruler by using some geometric primitives, a geometric primitive for encoding a '1' being different from a geometric primitive for encoding a '0', both having the same horizontal projection. The horizontal projection is then used for fine interpolation, achieving nanometer-scale resolution.
