Abstract: A percussive machine comprises a housing (10) with a cylinder (11) therein, in which a reciprocating drive piston (40) via a gas cushion in a working chamber (44) repeatedly drives a hammer piston (15) to impact on the neck (17) of a tool (20) carried by the housing (10). At empty blows with the neck (17) out of reach, the hammer piston (15) is thrown forwardly and caught pneumatically in a braking chamber (47) at the bottom end (12) of the cylinder (11). The braking is combined with an elastic yielding of the bottom end (12) against the action of a recoil spring (23) in the housing (10). The pressure in the braking chamber (47) during such yielding is controlled by throttling apertures (48) in the cylinder (11) uncovered by the bottom end (12). The hammer piston (15) is thus checked to halt pneumatically by throttling avoiding to collide with the bottom end (12) and takes inactive position below ports (46) in the cylinder wall through which the working chamber (44) is relieved and ventilated. The bottom end (12) is returned upon yielding by the recoil spring (23) and closes the throttling apertures (48) by check valve action.

Abstract: An embodiment of the present invention is a shipboard GPS positioning system (12) having data links (28, 30, 32, 34) to outlying tailbuoys (18, 20, 22, 24) requipped with respective GPS receivers. On ship (12), an Intel 386-based microcomputer system collects data from various ship's equipment including the ship's GPS receiver and data from the several tailbuoy units (18, 20, 22, 24). A computer-implemented process located in the microcomputer system controls the following processes. Periodically each GPS receiver produces updated pseudo ranges (PRs) and these are time-tagged. The time-tagged PRs for the ship (12) are aligned according to their time tags with their counterpart PRs from the tailbuoys (18, 20, 22, 24). The raw PRs are then passed through a Kalman mathematical filter to produce filtered pseudo ranges       
     A position solution is then attempted for each GPS receiver using the 
           The filters provide statistical data that is used to rate the quality of each 
           in a weighted least squares solution process. Special measures are included to provide quality control/quality assurance, including the user of error ellipses on the display to present a graphic indication of expected solution accuracy, and the use of real time fault detection, isolation, and correction algorithms when redundant satellite information is available.

Abstract: An idle speed regulating system for an internal combustion engine (10) operating according to a fuel based control strategy determines the amount of fuel delivered the engine directly as a function of the demand for engine output power and controls the amount of air supplied to the engine as a function of the quantity of delivered fuel. The system senses the actual idling rotational speed of the engine (10), derives a desired idling speed for the engine (10), and reduces the difference between the desired and actual idling speeds by adjusting the flow rate of the quantity of fuel delivered to the engine as a function of the difference between the desired and actual idling speeds. The rate of fuel flow is adjusted on the basis of a sum of an open-loop feedforward value, a closed-loop feedback value, and preferably an adaptive learning correction value.

Abstract: An object to be inspected is, for example, a medical capsule (c) having differently colored surface areas. A beam splitter (3) divides light reflected by the surface of the object into two parts. Each of the divided parts of the light is passed through an optical filter (4,5) whose transmission wavelength range is set according to the colors of the object, to adjust the quantity of transmitted light from a high-brightness part of the object surface and the quantity of transmitted light from a low-brightness part of the object surface to a reference level. Image pick-up (6,7) elements pick up images of the object surface according to the divided parts of the light and provide image signals. One of the image signals is selected and provided outside. Unlike the prior art that adjusts levels of signals by amplifying the signals according to the brightness of an inspected object, the method and apparatus described here do not involve amplification. Thus, noise components are never amplified to cause errors in inspection, thereby improving inspection accuracy.
