Abstract: This invention relates to a device comprised of at least two interchangeable modules, wherein at least one module has a power source and/or data storage unit and can transmit power and/or data to all of the electrically and mechanically mated modules. The device is designed for use in extreme weather environments, such as but not limited to, snow, rain, at elevation, and/or under pressure. In addition, each mating point between the at least two modules is waterproof. In a preferred embodiment, the device is comprised of a first module that is an optical head, with at least two optical lenses and can sense and capture image data. A second module is a handle comprised of a battery. When the first and second modules are electrically and mechanically mated, the two modules are secure and waterproof and the device operates as a 360° optical camera with an interchangeable power handle module.

Abstract: An improved numerical technique is disclosed for processing digital photo-graphs for measuring surface strain by speckle photogrammetry. The data to be processed is obtained by recording two digital photographs of speckle patterns of the image of the surface of an object where one photograph is recorded before a stress is applied and the other recorded afterward. In the case of a vibratory stress, the recordings are made by illuminating the object stroboscopically first at one extreme of its vibration cycle for the first photograph and then at the other extreme for the second photograph. Each photograph is divided into sectors and digital Fourier transforms are performed on each sector. The phase of these transforms is calculated for each image sector on both photographs, the resulting phase functions from the unstressed recording are subtracted from the corresponding phase functions on the stressed recording, and the results wrapped into a numerical range of ?pi to plus pi.

Abstract: A coprocessor in an image processing system is coupled to the bus to which a CPU and RAM holding image data are also coupled. The coprocessor extracts an input pixel stream corresponding to input images from selected bus transactions, performs computations on the input stream to produce output pixel streams corresponding to output images, and inserts the output pixel streams into selected CPU-to-memory bus transactions so that the memory stores the data. The CPU generates the selected bus transactions with specially marked address and/or control signals. The coprocessor includes a lookup table, and a first row delay. The row delay accumulates the three most recent rows of input pixels, which are sent to Sobel and rank processing sections for neighborhood processing. The results are thresholded and formatted, and are either output directly or passed through an additional pair of row delays to accumulate three rows of result data for neighborhood peak detection.

Abstract: A hand-held electronic dice game randomly generates pictorial representations of a plurality of die faces in display windows. Players' scores are determined by comparing wagers made by a player to a predetermined scoring schedule. The hand-held electronic disce game displays the score each turn and accumulated running scores.

Abstract: A method for a plurality of players each having a turn and a score to play a dice game using a plurality of dice and comprising the steps of throwing one die of the plurality of dice by each player of the plurality of players so as to decide which player of the plurality of players is the first player, throwing the plurality of dice in turn by each player of the plurality of players so that the dice game may begin, removing at least one die from the plurality of dice in turn by each player of the plurality of players so that each player may continue playing the turn, throwing in turn the remaining dice of the plurality of dice by each player of the plurality of players, throwing continually in turn the remaining dice of the plurality of dice by each player of the plurality of players until a score is reached and a decision to continue is made by each player of the plurality of players, and throwing the plurality of dice by each player of the plurality of players until a winning score is reached.
