摘要:
A system for detecting network intrusions and other conditions in a network is described. The system includes a plurality of collector devices that are disposed to collect data and statistical information on packets that are sent between nodes on a network. An aggregator device is disposed to receive data and statistical information from the plurality of collector devices. The aggregator device produces a connection table that maps each node on the network to a record that stores information about traffic to or from the node. The aggregator runs processes that determine network events from aggregating of anomalies into network events.

A data input system has a key pad with a plurality of keys and a display. The selected key is displayed in the display, but the character size of the selected key on the display is small and difficult to recognize. The face of the selected key appears on the display as a pop-up display in an enlarged scale. Thus, it is easy to recognize the selected key.

A system for sensing velocity of a wheeled vehicle has a flexible arm connected to a speed sensor and wireless transmitter at one end and to an adjustable strap or clamp at the other end. The strap is attached near the wheel to be measured. The sensor can then be positioned via the flexible arm to a location immediately adjacent the wheel. There is also a display unit connected to another strap or clamp. The display unit contains a wireless receiver that receives the data transmitted by the transmitter on the sensor, and a microprocessor that calculates the data and displays it for the user to view. A magnetic strip is attached directly to one of the wheels of the device. As the wheel rotates, the magnetic strip passes by the sensor positioned adjacent the wheel, and this passage is recorded by the sensor.

A method for determining a structural image of a pane, the structural image being suitable for the detection of a visibility impairment of the pane, especially raindrops. The method includes a step of removing a background brightness from an image of the pane, on which image a surface of the pane is shown in focus and a background of the pane is shown out of focus, in order to determine a structural image of the pane. In a further step, accentuation of image structures present in the structural image is carried out in order to determine an enhanced structural image of the pane.

The data protection management apparatus protects digital licenses and digital data, so that the abuse and illegal use of digital data is prevented. The apparatus has an I/O port, session manager, license management engine, usage rules administrator, encryption engine, memory manager, and memory. The license management engine acquires, stores, and manages licenses in sessions opened by the session manager, and the usage rules administrator provides an encryption algorithm and protocol for securely storing and sending digital license data by applying the usage rules to the use of licenses managed by the license management engine.
摘要:
An apparatus for transmitting sound in a motor vehicle including a housing (1) with an inside partition (2), which together define or delimit two separate subspaces (3, 4), which in turn are separated by a transmission valve (6) which opens through the partition (2) and can pivot about a pivot axis (5). The first subspace (3) is connected to an intake manifold of an internal combustion engine, and the second subspace (4) is connected to an interior of the motor vehicle. An elastic and at least partially perforated sealing element (8) is provided in a gap (25) between a peripheral edge (7) of the transmission valve (6) and the housing (1).
