The invention discloses a method for moving targets tracking and number counting, comprising the steps of: a). acquiring continuously the video images comprising moving targets; b). acquiring the video image of a current frame, and pre-processing the video image of the current frame; c). segmenting the target region of the processed image, and extracting the target region; d). matching the target region of the current frame obtained in step c) with that of the previous frame based on an online feature selection to establish a match tracking link; and e). determining the number of the targets corresponding to each match tracking link based on the target region tracks recorded by the match tracking link. The invention can solve the problem of low precision of the number statistic results caused by the bad environment, such as that the distribution of the illumination is extremely not equilibrium spatially, the change in a time period is complicated, the change of the gesture during the people goes by is evident, and the like, under the normal application condition.

A tablet division feeder includes a moving unit to move a tablet T, a fixing blade located in a movement path of the tablet T, and a support plate extending from the fixing blade such that divided tablets T2 on the fixing blade are transferred and kept onto the support plate. The fixing blade divides the tablet T into upper and lower divided tablets as the tablet T is moved in such a manner that the lower divided tablet T1 is discharged and the upper divided tablet T2 is transferred from the fixing blade to the support plate by the moving unit and kept on the support plate. The upper divided tablet T2 is discharged from the support plate as the upper divided tablet T2 is further moved by the moving unit in such a manner that the upper divided tablet T2 is discharged from the moving unit.

The invention discloses a note detecting / counting device which comprises a sensor unit, a computing unit and a control unit, wherein the sensor unit is used for converting output signals of multiple sensors distributed on a note transmission channel into transmission states representing whether a note exists, wherein each sensor is corresponding to a note counter; the computing unit is used for computing a note distance between the current detecting position of any sensor and the position of the front end of a currently detected note according to the transmission states output by the sensor unit; and the control unit is used for carrying out searching from the transmission states currently cumulatively output by the sensor unit once the note distance computed by the computing unit exceeds a note distance standard value, and when at least a transmission state representing that a note existence state is changed into a note absence state is searched, 1 is added to the count value of the note counter corresponding to the sensor, and when at least a transmission state representing that a note absence state is changed into a note existence state is searched, the fact that current notes are detected completely is determined, the position of the sensor (the note distance between the position of sensor and the front end of the currently detected note is closest to the note distance standard value) is taken as the position of the front end of a next detected note and the position is sent to the computing unit, so that the computing unit takes the position of the front end of the next detected note as a starting position so as to compute the next note distance. The invention also discloses a note detecting / counting method.

The present invention discloses a method of counting the number of MBMS subscribers, comprising: setting different types of notifications, each of which is designed to instruct UEs in at least one mode to respond said counting number of subscribers; the network side issuing different types of notifications, so as to monitor the activation of UEs in at least one mode in the MBMS with said notifications, and thereby achieving counting the number of subscribers of each MBMS. The method of counting the number of MBMS subscribers provided in the present invention can be used to perform counting the number of subscribers of each MBMS more accurately, so as to take fuller advantage of the precious air interface resource.

Pedestrian detection and counting for traffic intersection control analyzes characteristics of a field of view of a traffic detection zone to determine a location and size of a pedestrian area, and applies protocols for evaluating pixel content in the field of view to identify individual pedestrians. The location and size of a pedestrian area is determined based either on locations of vehicle and bicycle detection areas or on movement of various objects within the field of view. Automatic pedestrian speed calibration with a region of interest for pedestrian detection is accomplished using lane and other intersection markings in the field of view. Detection and counting further includes identifying a presence, volume, velocity and trajectory of pedestrians in the pedestrian area of the traffic detection zone.

A self-contained pill dispenser is disclosed. A housing is provided and a hopper for containing a plurality of pills is supported by the housing. A transport tube receives pills from the hopper. The transport tube has a controllable aperture for facilitating or inhibiting delivery of pills to the transport tube. A microcontroller is also operatively connected to the hopper, the transport tube, and the input aperture. Optionally, a feed chute can be operatively connected between the hopper and the transport tube. The system can self-calibrate the mechanism for counting and dispensing pills by dynamically adjusting the input aperture based upon the stored information representative of the pulse width signal and the amplitude signal.
