Granted: 2000-04-25
Abstract: A computer system is provided which allows keyboard access in a hands-free environment. An orientation sensor is mounted on a headset and provides a cartesian positional input to an interface. The device functions in either a cursor control mode or a keyboard simulation mode. In keyboard simulation mode, positional inputs are converted to keyboard input codes which are input to a standard keyboard controller. The key codes generated are displayed to a user on an LED display. A microphone on the headset connects to voice control circuitry of the interface which allows input selections to be made through voice commands. A user locates the desired keyboard input by observing the LED display and selects the input with a vocal command. RAM memory storage of keyboard inputs allows the system to appear as a manual keyboard from the perspective of the keyboard controller.

Abstract: Complex graphs are difficult to display legibly on computer display screens. Attempts have been made in the prior art to collapse  or  truncate  the  graphs  so  as  to  only  display portions of the graph. However,  these prior art processes have not been effective in dealing with cyclic or acyclic graphs.  The present invention overcomes these problems of the prior art by providing a process in which all nodes affected by the truncation operation are identified and are only removed from the portion of the graph being displayed when their removal will not result in displaying incorrect or false information. The process consists of viewing all nodes interconnected either directly or indirectly to any node selected for collapse or truncation.

Title: Horizontal line counter insensitive to large phase shifts of video
Inventor: TULTS JURI
IPC: H04N7/088
Filed: 1992-06-15
Granted: 2001-08-28
Abstract: A horizontal line counter (110, 115, 120) provides a signal (LINE Nr. 21) identifying the beginning of video data in a parti-cular horizontal video line. The counter is clocked by multiple clock signals.  A first clock signal (HOR PLS) clocks the counter un-til the tine count value equals a known value that is less than the line number of the horizontal line that is to be identified. When the count value equals the known value, clocking by a second clock signal (COMP SYNC) is enabled. Although, the first clock source provides a regular pulse waveform suitable for clocking the counter reliably, transitions on the first clock signal may not accurately indicate the beginning of information within a horizontal line interval. Transitions on the second clock signal accurate-ly indicate he beginning of the desired information. However, the wave form of the second clock signal may exhibit irregularities prior to the time at which clocking by the second clock signal is enabled that could adversely affect the reliability of the counter value. The combined clocking arrangement advantageously provides significantly higher reliability of the count value and im-proves the timing of the line identification signal with respect to the beginning of the desired video data.

Abstract: In a packet switched network, each network node has line and trunk ports to which LAN user terminals and links are connected and which are identified by a port address containing a node number plus a port number. The user terminals transmit a signaling packet when establishing a connection before sending information-bearing packets, containing in it a source network address (a protocol identifier plus a source user address) and a destination network address (the same protocol identifier and a destination user address). Each network node includes a memory for establishing correspondences between the network addresses of remote user terminals, the port addresses of the remote user terminals, and the port numbers of the ports of the network node through which local user terminals are accessible to the remote user terminals. The network node responds to the signaling packet from a user by detecting in the memory a corresponding port address and a corresponding port number and appending the detected port address to the packet and transmitting it to one of the ports of the node according to the detected port number.

Granted: 2005-08-16
Abstract: A portion of film, with a length proportionate to the dimensions and to the characteristics of the product to be wrapped, is subjected to a transverse pre-stretch-ing, the extent of which is also proportionate to the said parameters. The film is held at one end by a fixed dispenser (30) and at the other end by a movable rear clamp (61), which conveniently reduce the longitudinal tension of the film, both in pre-stretching and during the subsequent lifting of the product. In this phase, the side clamps (78-178) approach each other to reduce the pre-stretching, and are then inserted under the product and are opened, to extend the side flaps of the film under the product. This is followed by the operation, as a group, of the rear folder (52), which extends under the product a portion of the film held by the associated rear clamp (61), and the pusher (55) which pushes the product on to the front folder (37), while a final flap of film is drawn from the fixed dispenser (30), ie extended over the whole length of the bottom of the product, is cut to size, and is disposed under the side flaps and the rear flap, which has been released at the correct time by the said rear clamp.

Abstract: A method for curing a photosensitive resin composition includes use of an especially thin gauge protective cover film, preferably incorporating a coating to permit ease of removal after imaging. The method also uses a photosensitive resin composition incorporating a photospeed modified capping layer to selectively retard image growth during exposure. To eliminate undesirable defects in the cured photopolymer, a glass plate which had previously contacted and flattened the composition, is separated from the composition by at least 0.064 cm (at least 0.025 inches) after partially curing the composition but prior to completely curing the composition. The partial cure of the composition is achieved by directing light to the composition from a source of actinic radiation positioned about 15.2 cm to about 76.2 cm (about 6 to 30 inches) from the resin composition, where the actinic radiation has a wavelength of maximum intensity of about 365 to about 375 nm.
