Title: Method for controlling computer network security
Inventor: SHWED GIL
IPC: H04L9/00
Filed: 1994-12-14
Granted: 2008-06-17
Abstract: A filter module allows controlling network security by specifying security rules for traffic in the network and accepting or dropping communication packets according to these security rules. A set of security rules are defined in a high level form and are translated into a packet filter code. The packet filter code is loaded into packet filter modules located in strategic points in the network. Each packet transmitted or received at these locations is inspected by performing the instructions in the packet filter code. The result of the packet filter code operation decides whether to accept (pass) or reject (drop) the packet, disallowing the communication attempt.

Abstract: A light scanner for determining the configuration of elongated objects, such as logs or lumber, is described. The object is moved laterally through the scanner past a plurality of laser light sources and a plurality of photo-detector cameras spaced along the object. The coherent laser light beams are parallel to each other and to the lens axis centerline of the cameras for easier alignment and to prevent the laser light spot on the object from moving relative to such axis centerline for objects of different thickness.      The cameras have a photo-detector target which may be a linear diode array CCD semiconductor device for producing scan data signals in response to reflected light beams which are processed by a computer system giving preference to the data produced by the beams in the outer portions of the camera viewing field to determine the thickness of the object at points spaced along the object. Non-coherent polychromatic light is also reflected from the object to the cameras to detect the ends of the object and to determine its length.      Reference targets are provided along one side of the object to sense the leading end and the trailing edge of the object as it is moved laterally to block light reflected from or emitted by such targets to the cameras on the opposite side of the object.

Title: Ink container having plural porous members for storing ink and ink jet apparatus having said ink container
Inventor: UJITA TOSHIHIKO
IPC: B41J2/175
Filed: 1995-01-30
Granted: 1999-12-07
Abstract: An ink container for storing ink and an ink jet apparatus having such an ink container is provided. The ink container has an ink tank providing an enclosed space within an inner wall of the tank. The ink container is filled with inner and outer porous members having open pores for holding ink. The inner porous members are disposed within the enclosed space so as to only contact and press against other inner or outer porous members or both. The outer porous members are disposed within the enclosed space so as to contact and press against the inner porous members and the inner wall of the ink tank. This arrangement of inner and outer porous members within the ink container prevents an uneven compression distribution which occurs when conventional porous members are inserted into ink containers or when ink containers containing such conventional porous members suffer impacts. Further, the porous members can fill the entire ink container regardless of the shape of its interior, thus reducing the amount of non-dischargeable ink and leakage.

Abstract: A network includes a system and a population of subscriber units. System satellites move in low earth orbits and form moving cells on the surface of the earth. A pattern of static areas that covers the service area of the system is defined in a map. The system discovers the static areas for the subscriber units. When an incoming call needs to be directed to a subscriber unit, the subscriber unit's static area is converted into identities of beams that form the cells that coincide with the static area. A ring signal is transmitted in only these cells. Subscriber units monitor area identification signals that identify the static areas coincident with the cells where the signals are transmitted. When the static area known by the system is not among the identified static areas, a subscriber unit engages in re-registration communications.

Abstract: A low ink sensing system is combined with an ink cartridge detection system to enable a more efficient ink jet printer. An ink container which supplies ink to an associated printhead is modified by the incorporation of two light directing elements, in the preferred embodiment, a faceted prism and a roof mirror, into a transparent wall of the container housing. The cartridge, comprising the ink container and associated printhead, is mounted on a scan carriage. Periodically, the carriage is conveyed to a sensing station comprising a pair of light sources and a commonly used photosensor. A first light source is energized and a beam of light is directed to a location where the roof mirror, would be positioned if the cartridge is present. If the cartridge is absent, lack of a reflected return signal is sensed, indicating a cartridge has not been inserted. Print operation is halted until a cartridge is inserted. If a cartridge is properly inserted, the roof mirror returns most of the incident light to the photosensor which generates a signal indicating the presence of the cartridge. A second light source is then energized and directed towards the faceted prism, which is either immersed in ink or exposed to air within the interior of the container. If the latter, light is internally reflected by the prism facets back to the photosensor. If a print operation has been in progress, and the ink level has fallen, the common photosensor detects either a strong or weak redirected light component and initiates a status check and generates appropriate displays of low ink level or out of ink warnings.

Abstract: The present invention relates to a hydrocopter. A hydrocopter is a vehicle b y which it is possible to move over water, particularly in an archipelago, under difficult conditions, e.g. during the thaw. The wat erproof hull of the hydrocopter bears against the underl ying surface, such as snow, ice, slush or water, and is driven forward by a prope ller mounted on top of the hull. The problem with the cu rrent hydrocopters is that they are very difficult to steer and uncomfortable to r ide in. Division of the hydrocopter hull into two portio ns (1, 2) connected to each other by a hinge joint (3), in accordance with the inventi on, makes it possible to use frame steering. This new st ructure makes the hydrocopter easier to handle. The invention provides a vehicle whi ch has a small turning radius and which is steerable eve n at very slow speeds.
