A projection system includes an image projector, an invisible light transmitter and an invisible light sensor. The image projector is used for projecting a projection image on a physical plane. The invisible light transmitter is used for generating an invisible light plane, which is parallel with the physical plane. The invisible light sensor is in communication with the image projector. When a pointing object is placed on a touching point, an invisible light beam reflected from the pointing object is received by the invisible light sensor. According to the invisible light beam, a sensing signal indicative of a spatial coordinate position of the touching point is acquired and transmitted to the image projector. The image projector recognizes and calculates the spatial coordinate position of the touching point according to the sensing signal and performs a controlling action according to the spatial coordinate position.

A system and method for performing real-time quality inspection of objects is disclosed. The system and method include a transport to move objects being inspected, allowing the inspection to be performed in-line. At least one optical acquisition unit is provided that captured optical images of the objects being inspected.

The point clouds are compared to the extracted CAD models for each object, where CTF are compared to user input or CAD model information and the object is determined to be acceptable or defective based on the extent of deviation between the point cloud and the CAD model.

The size of a pointing object is determined based on a detection result of a touch operation with a pointing object, and the number of electrodes in a group is switched according to the size of the pointing object. In particular, the size of the pointing object is categorized into three groups based on the size of an adult's finger, a child's finger, and a stylus, and the number of electrodes in a group is set to three levels. The number of electrodes in a group varies according to powers of two, such as two, four, and eight.

A mechanism for the flow of access by derivation is provided. An access point may be any object, such as files or functions, to which the access recipient is granted access rights by the access provider. Access is typically represented by a relationship object referencing the access provider function, the access recipient function, and the access point object, and a set of access rights. This membership access relationship object is typically represented as a subtype of the access relationship. When a membership access relationship is created, typically a new associated persona function is generated, representing the new identity created for the access recipient function while serving as a member of the access point function. When a persona function is invited to be a member in another function, that in turn generates a membership and a second persona that is derived from the first persona, resulting in identity derivation.

A method for determining an actual trajectory of a vehicle using object detection data and vehicle dynamics data. An object detection system identifies point objects and extended objects in proximity to the vehicle, where the point objects are less than a meter in length and width. An updated vehicle pose is calculated which optimally transposes the point objects in the scan data to a target list of previously-identified point objects. The updated vehicle pose is further refined by iteratively calculating a pose which optimally transposes the extended objects in the scan data to a target model of previously-identified extended objects, where the iteration is used to simultaneously determine a probability coefficient relating the scan data to the target model. The updated vehicle pose is used to identify the actual trajectory of the vehicle, which is compared to a planned path in a collision avoidance system.

A turning point marker on a power gauge and an impact point object are displayed in a game image. The impact point object is displayed according to the current lie. The turning point marker is positioned away from the left end of the power gauge depending on the difficulty of the shot. The moving direction of a cursor moving along the power gauge is reversed at the turning point marker. With the turning point marker, it is possible to clearly indicate to the player how limited the power available is under the current situation as compared with the situation where the maximum power is available, and thus how difficult it is to play the current situation.

The invention relates to a system for enlarging a retinal image, comprising an intraocular implant and an external lens. The implant comprises a peripheral part and a central part with a negative power. The lens has a positive power and is for arrangement outside the eye, typically in a glasses frame. The lens and the implant produce an enlarged image of an object at the back of the eye of a standard user. For a pupil with a diameter of 1.5 mm, each point object in a reading field forms a dark image of a size between 20 and 50 μm at the back of the eye. The invention permits a large reading field, at the cost of a degradation in the performance of the system along the axis, acceptable when taking into account the acuity of the patients treated and, furthermore, provides a system with little variation in performance with displacement of the lens from the nominal position.
