Abstract:
A timing method for a sports competition at the same time on different sites (4) around the world. In a first phase, all time bases of the timing devices, of a start coordinator device (3) and of each site are synchronised. Next, a measurement of the transmission times between the start coordinator device and each site is performed to determine a maximum transmission time. The start coordinator device establishes a start time equal to the time of the date of each site and while adding a time difference longer than the determined maximum transmission time. The start time is adapted to each site where the competition takes place to automatically order, by each timing device, the start of the competition at the same time on each site and on the base site of the start coordinator device to have a sports competition taking place live on all competition sites.

An imaging device for a photo finish system, including a first camera aligned on a finish line and a mechanism for display of three dimensional stereoscopic images.
Abstract:
A display method including the steps of: acquiring, at a first predetermined frequency, a first series of one-spatial-dimensional instant images of the finish line of a race; simultaneously acquiring a second series of two spatial-dimensional instant images of the same finish line (19) at a second predetermined frequency; forming a temporal image (10) of the photo finish type from the first series of instant images; choosing an instant (15, 22) of the temporal image (10); analysing a two-spatial-dimensional image of the second series, the image being correlated with the selected instant (15, 22) to determine at least one distance; and displaying the analysed two-dimensional image with the determined distance or distances. Also, a display system for implementing the method.
Abstract:
Method for the adjustment of a photo finish camera including a matrix color filter, characterized in that the method includes the following steps: a first step of selecting a basic pattern having optical properties of sensitivity, of color quality and of resolution which are predefined according to race parameters; a second step of software selection of a set of adjacent columns whose number corresponds to the width of said selected basic pattern; a third step of centering said set of adjacent columns on the finish line.
Abstract:
The process enables a time of an athlete in a hurdle race to be measured or predicted with a personalized transponder module positioned on the athlete and a base station. The transponder module comprises a receiver unit, a processing unit, a transmitter unit for data signals and a motion sensor to supply measurement signals to the processing unit. The module is activated by a wake-up signal and a measurement of the movement is conducted by the sensor after the start of the race on passage of each hurdle. The data signals are transmitted to the base station and determination of a passage time over each hurdle is conducted.
Abstract:
Color filter for a digital sensor formed of a two-dimensional array of pixels, each pixel corresponding to a given color. The pixels are arranged in at least one base pattern repeated over a given surface, which has at least three pixels of three different colors. The color filter is characterized in that it includes a plurality of distinct base patterns, each of these patterns having predefined optical properties of sensitivity, of color quality and of resolution, and in that it is subdivided into a plurality of distinct areas, each corresponding to a two-dimensional sub-array of pixels. Each of the base patterns is repeated several times along each dimension of the two-dimensional sub-array, respectively over the entirety of a corresponding area.
