Abstract: An apparatus for converting measurement signals into digital signals suitable for processing in a microprocessor (12), with the signals having been initiated in a piezo sensor (6) by accelerations acting on the sensor during the impacts of a percussion device (1), particularly a hydraulic hammer, and being used to determine the number of work strokes that have been executed in the impact direction (arrow 3) of the percussion device (1).

Abstract: A fault detection apparatus for use in an electrical distribution network to distinguish normal network operations from various network faults. Pre-event and post-vent signal patterns are compared and analyzed to produce an event characteristic which distinguishes the faulted feeder and the faulted phase. The characteristic also allows for discrimination between the various events and controls network response accordingly.

Abstract: In a telephone system employing a PBX server to communicate with local telephones over a local area network, fallback adapters are provided to automatically respond to a power failure and also respond to the failure of the PBX server to automatically connect the telephones directly to a telephone line. This automatic connection enables the telephones to be used as analog phones and make and receive calls directly without using the PBX server. Power failure is detected by relays which default to a position to connect the telephones directly to the telephone line. The fallback detectors have controller logic which detects the presence of a ringing signal on the telephone line and the failure of the PBX to respond to the ringing signal. In addition, the fallback detectors detect the failure of the PBX to respond when a telephone is used to attempt to make an outgoing call or a call to another one of the local telephones.

Abstract: A windup window shade is provided with windup window shade means which, in the extracted state, make possible different degrees of opacity at the window. To this end, the two window shade web can either be wound on separate windup shafts and spread out in the same direction from the same starting point, or the two window shade webs have been connected with each other and, after having been extended, are moved in the manner of a film in front of the window. Two windup shafts are employed in both cases, wherein in the one case the two windup shafts are located directly next to each other, while in the other case the windup shafts are separated from each other during the extension of the shade.

Abstract: In a system for displaying medical images, medical images are generated from views internally within a body by means of x-rays, CAT scan, or MRI. The images are spaced in time or are views of spaced slices through tissue or through an organ within a body. The spacing between the images is such that the display of the images as a motion picture would result in the motion being depicted as jerky in the motion picture. A video processor generates dense motion vector fields between adjacent frames of the original set of images and, from the dense motion vector fields, generates interpolated images between the images of the original set. The interpolated images are assembled into a motion picture set of images, which are displayed by a video display device.

Abstract: A method of restricting file access is disclosed wherein a set of file write access commands are determined from data stored within a storage medium. The set of file write access commands are for the entire storage medium. Any matching file write access command provided to the file system for that storage medium results in an error message. Other file write access commands are, however, passed onto a device driver for the storage medium and are implemented. In this way commands such as file delete and file overwrite can be disabled for an entire storage medium.

A system and method for assigning future slots of a transmission frame to a data packet in the transmission frame for transmission over a wireless telecommunication network system includes applying an advanced reservation algorithm, reserving a first slot for a first data packet of an internet protocol (IP) flow in a future transmission frame based on the algorithm, reserving a second slot for a second data packet of the IP flow in a transmission frame subsequent in time to the future transmission frame based on the algorithm, wherein the second data packet is placed in the second slot in an isochronous manner to the placement of the first data packet in the first slot. There may be a periodic variation between the placement of the first data packet in the first slot and the placement of second data packet in the second slot or no periodic variation between placements of slots.

Abstract: A method is disclosed for accessing a removable storage medium. The removable storage medium is inserted within a removable storage drive. When the newly inserted removable storage medium is detected, an identifier is read therefrom. The identifier is used to determine if a symbolic link to that medium already exists. When a symbolic link exists, the symbolic link is updated to reflect the physical path to the storage medium. When the symbolic link does not exist, a symbolic link is created linking the identifier to the storage medium. The symbolic link indicates a non-standard storage medium. The symbolic link is then used to read data from and write data to the storage medium.
