Abstract: A self-tonometry device for measuring intra-ocular pressure in an eye of a subject, may include a plurality of sensors and a processor for executing a machine learning module. The plurality of sensors may be arranged in an array for measuring a plurality of pressures at respective positions on an eye of a subject, when the plurality of sensors in the array apply a force to the eye at the respective positions through an eyelid of the subject. The processor may be configured to receive the plurality of pressures at the respective location from the plurality of sensors, and to compute using the machine learning module, an intra-ocular pressure in the eye based on the plurality of pressures measured at the respective positions through the eyelid of the subject.

Abstract: Operations in a worksite (20) are managed by networking at least some items of apparatus (4, 16, 24, 26, 30, 28, 34) which perform tasks in connection with said worksite and which receive and/or send data. The items of apparatus are organized in hierarchical levels according to a determined dependency relationship of the worksite. Communications are made with an electronic data network comprising management means (74, 76, 66, 64) cooperating with a plurality of communications interfaces (42-46), a given item of apparatus having a data link with a specified communications interface. The management means stores a correspondence between each item of apparatus and an address structure reflecting the hierarchical position of that item of apparatus (4, 16, 24, 26, 30, 28, 34) in the determined dependency relationship of the worksite.

Abstract: The invention relates to a method for controlling a surface-modifying machine, wherein information on the desired condition and on the actual condition of ground to be prepared is provided and is used to derive control statements for the machine based on a comparison of the desired and the actual condition. The information on the actual condition is represented by a point cloud as a spatial distribution of discrete surface points. In order to derive control statements, at least two surface points each from the point cloud are used for every horizontal position so that non-differentiated information can be derived that for example also allow to identify various planes.
