摘要:
A method and an apparatus for enumerating one or more specific elements within a biologic fluid sample are provided. An embodiment of the method includes the steps of: a) providing a chamber formed between a first planar member that is transparent and a second planar member, which members are separated from one another by a substantially uniform height; b) introducing the biologic fluid sample into the chamber, wherein the chamber height is sized such that the sample extends between the first and second members, and sized relative to the specific elements within the sample such that the specific elements non-uniformly distribute within the sample upon introduction into the chamber; c) examining substantially all of the sample within the chamber and enumerating all of at least one of the specific elements; d) determining the volume of sample contained within the chamber; and e) determining the number of the at least one of the specific elements per unit volume.

It is based on an apparatus (1) forming a closed chamber (2) inside of which is installed an upper centered digital camera (15) oriented toward a removable support (17) over which is placed either a panel fitted with receptacles for holding the liquid culture mediums or a plate for placing on it a solid culture medium, the support (17) being located between lower lighting means (18) and upper lateral lighting means (19) complemented with light diffusers (20) and (21). The apparatus includes external operation indicators, switches, outlets and connections providing for appropriate operation and control through a central computer. The system captures and interprets the images produced by the reactions taking place in said culture mediums, either liquid or solid, allowing the bacterial reactions to be converted into values, in addition to analyzing microorganism growth.

The apparatus of the present invention for determining existential conditions of objects on a certain detecting region, includes: a temperature distribution detecting section for obtaining a thermal image including a plurality of elements each having temperature data by detecting the temperature distribution on the detecting region; an element classifying section for classifying the plurality of elements in the thermal image into at least two groups, all elements belonging to one of the groups being in a certain temperature range, the temperature range of the one group being distinct from a temperature range of another one of the groups; a group selecting section for selecting at least one group of a relatively higher temperature range in the thermal image from the at least two groups; an element selecting section for selecting, among elements included in the selected group, elements having temperature data indicative of local temperature peaks in the thermal image; and an output section for outputting the number of the selected elements by the element selecting means as the number of objects on the detecting region.
摘要:
An apparatus (10) for counting discrete objects (30) of various sizes and shapes as they travel through the apparatus in a disorderly flow. The apparatus includes a sensor array (25a) which comprises a plurality of photodetectors (38) arranged in a linear fashion. The discrete objects are passed over the sensor array. By utilizing the sensor array as a means for obtaining information about the discrete objects, the apparatus samples the sensor array at predetermined time intervals, examines the various contours of the images produced through the sampling and based upon predetermined criteria determines whether an image represents one or more objects.
摘要:
In a defect counting method and apparatus, a projection or a corner of a defect area is successively identified from a pixel and pixels close to the pixel, especially, from four pixel groups. The number of defect areas is incremented when the projection is identified and decremented when the corner is identified.
摘要:
Method for detecting insects using an insect trap and detection device (10) and a post-processing platform (5), by determining a total probability P tatal of a detection event signalled by the insect trap and detection device (10). Pre-processing the sensor signal (2a) is obtained by applying a detection algorithm and a subsequent buffering algorithm to obtain a detector signal (3a) using parameters N det , N cool , N pre , N post , W buff and B buff . Optionally also a blocking algorithm is applied, and a post-processing algorithm can be applied to a plurality of detection signatures obtained from the detection records (3a) in the received detector signal (3a, 3b). The insect trap and detection device (10) has a sensor channel (12) and a beam interrupt sensor (2) positioned in the sensor channel (12), and a local processing unit (3) connected to the beam interrupt sensor (2) and to a transmitter unit (4).

Provided is a counting apparatus capable of accurately counting count target objects. A counting apparatus 1 includes: a storage unit 11 in which a learning model is stored, the learning model being trained using multiple pairs of training input images each obtained by capturing an image of multiple count target objects with the same shape, and training output images each containing teaching figures that are arranged at respective positions of the multiple count target objects; a captured image acquiring unit 12 that acquires a captured image of multiple count target objects; an output image acquiring unit 13 that acquires an output image in which the count target objects contained in the captured image are converted into count target figures, by applying the captured image to the learning model; a counting unit 15 that counts the number of count target objects, using the multiple count target figures contained in the output image; and an output unit 16 that outputs the number of count target objects counted by the counting unit 15.
