A processor supports instruction pointer (IP) relative addressing in at least one operating mode of the processor. For example, in some implementations, IP relative addressing is supported in an operating mode or modes in which the address size is greater than 32 bits (e.g. up to 64 bits). In some embodiments, the displacement may be limited to less than the address size (e.g. 32 bits, in one implementation) when such operating modes are active. Code density may be higher than if the displacemen...

A watch comprising a motor driving in rotation a first rotary hour indicator at a period of 1/N revolution per day, and a second rotary minute indicator driven by a concentric axis. The invention is characterized in that the minute indicator (13, 23) is driven at a speed (N+1)/N revolutions per day, N being a whole number.

A graphics system and method for rendering image on a display device. The graphics system receives 3D graphics data including vertices for a triangle. The triangle is tested to determine if it is larger than a maximum triangle size, and if so, it is fragmented into sub-triangles smaller than the maximum size. After this size limiting, a bin bounding box is computed for each triangle. The absolute coordinate of a triangle's vertices are converted into relative coordinates with respect to an origi...

A navigation system for navigating an autonomous vehicle along a path that is confined by walls that are within range of on-board sensors is described. The system determines the relative location and orientation of the walls with respect to the vehicle. The system controls the steering angle and the ground speed of the vehicle by employing: (a) range data to establish free space in front of vehicle; (b) active contours to generate a desired path; (c) driving hints to guide the active contours al...

A method of measuring relative channel delay between components of a video signal includes removing a local mean from each of the pair of input component signals and cross-correlating the resulting pair of input component signals. A mean is removed from the cross-correlation and a centroid for the cross-correlation is found within a region bound by nearest zero-crossing to a peak in the cross-correlation. The centroid is then converted to a delay time as a function of sample rate after removing ...

Method and system for measuring a relative position and orientation of range cameras using a movement of an object within a scene. In general, the method and system determine the relative pose between two cameras by measuring a path the movement of the object makes within a scene and calculating transformation parameters based on these measurements. These transformation parameters are used to determine the relative position of each camera with respect to a base camera. The system and method incl...

A pressure sensor for measuring a pressure difference between a pressure being measured and the ambient atmospheric pressure surrounding the pressure sensor, including a platform and a membrane loadable with a pressure being measured. The membrane is secured at its edge to the platform, with a pressure chamber thus being formed between the platform and the measuring membrane. The pressure chamber communicates over a reference air path with the atmosphere, with the reference air path being a wind...

Method to coil metal wire made of steel arriving directly from an in-line rolling plant, in which the metal wire is delivered to a rotating loop-forming head (11) cooperating coaxially with a hollow drum (12) to form the coil (13), the hollow drum (12) having a controlled rotary movement, the relative speed of the loop-forming head (11) and the drum (12) together being functional to the layer being formed, the drum (12) being associated with an alternate axial moving system. Device to coil metal...

A construction modification and associated method used in pre-stressed building structures is designed to enhance resistance to extreme high wind environments, such as hurricanes and tornadoes, and in earthquake prone regions is most useful for structures built of lightweight materials such as wood or aluminum but is also applicable to structures built of heavy materials such as brick, stone, concrete, reinforced concrete and steel. Modifications include increased spacing of the wall frame eleme...

In order to produce relative velocity signals in accordance with the relative velocity between a following and a preceding vehicle, a Doppler signal transmitter, which targets the preceding vehicle, is attached to the following vehicle. The thus obtained Doppler signals impinge on a signal processor which analyzes the frequency spectrum of the Doppler signal. Velocity signals are formed from the frequencies within this frequency spectrum, which frequencies lie outside the range of those frequenc...
