The present invention provides for systems and methods for dimming a LED matrix functioning as a backlight to an avionics display. A system according to an embodiment of the present invention comprises a processor for receiving inputs of ambient lighting and temperature, as well as light generated by the LED matrix. The processor provides modulated pulse wave signals (square waves) to two control circuits for controlling the LED matrix in two modes. At low dimming levels, the processor modulates the duty cycle of a first square wave for affecting the light level and maintains a minimal duty cycle of a second square wave. Once the highest light level is obtained by increasing the duty cycle of the first square wave, the processor then modulates a second square wave by increasing its duty cycle. The duty cycle of the second square wave is modified by a circuit to produce a voltage level which is provided as an input to control light level of the LED matrix. As the duty cycle of the second signal is increased, so is the voltage level provided to the LED matrix and the light generated by the LED matrix.

A method and apparatus is disclosed for improving the security of computer networks by providing a means operating passively on the network for detecting, reporting and responding to intruders. The system is comprised of a plurality of intruder sensor client computers and associated event correlation engines. Resident in the memory of the client computer and operating in the background is a Tactical Internet Device Protection (TIDP) component consisting of a passive intruder detector and a security Management Information Base (MIB). The passive intruder detector component of the TIDP passively monitors operations performed on the client computer and emits a Simple Network Management Protocol (SNMP) trap to an event correlation engine when it identifies a suspected intruder. The event correlation engine, through the use of a behavior model loaded in its memory, determines whether the user's activities are innocent or those of a perspective intruder. When the event correlation engine is unable to classify a user based on a single trap message, it can request historical information from the security MIB, a database of the operating history of the client computer including a chronology of the illegal operations performed on the client. Once the event correlation engine determines that an intruder is located at an associated client workstation, it generates a status message and transmits the message to all of its subscribers, informing them of the presence and location of a suspected intruder.

A current source generates, with high efficiency, a current that is substantially constant over a wide range of output voltages. This current is injected into the first end of a series-connected string (hereinafter referred to as string) of LEDs, with the second end of the string connected through a resistor to ground. The voltage developed across this resistor, which is a measure of current flow in the series string, is fed back to the current source, wherein feedback maintains nearly constant current output over a wide range of output voltages. A switch, such as a field effect transistor (FET) is placed in parallel with each LED in the string. A level shift gate driver couples a pulse width modulated control signal to the gate of each FET. When the FET across a particular LED is on, substantially all the current flows through the FET rather than the LED, and little or no light is emitted. Because the one resistance of the FET is very low, the power dissipated in the FET (current squared times resistance) is also very low. With the FET turned on, the forward voltage drop of the LED it is controlling drops to near zero, since little current is flowing through the LED. However, because the current source is designed to provide constant current over a wide range of output voltages, the current flow through the other LEDs in the series string changes little. When the FET is turned off, substantially all of the current flows through the associated LED, turning it on. By modulating the duty cycle of each FET, the brightness of each associated LED may be varied smoothly over its full range.

The invention concerns a multiparty accounts receivable and accounts payable system that allows business trading partners to use a single, shared system for both accounts receivable and accounts payable management. The system of the invention forms an electronic “bridge” between a plurality of business trading partners for purposes of invoicing, dispute resolution, financing, and settlement of single and multiple currency debts. As the invoicing and settlement activities of the participants are funneled through a common system, the system allows a participant to aggregate all debts owed to other participants, aggregate all debts owed by the other participants, and net debts owed to other participants with debts owed by these participants. After aggregation and netting, the participant issues a single payment to settle numerous accounts payable items, and receives a single payment that settles numerous accounts receivable items. The system allows participants to use the substantial amount of financial and cash flow information captured by the system to borrow more efficiently by permitting lenders to view this information. Furthermore, the system provides a confirmation process to convert existing debt obligations into a new, independent payment obligation due on a date certain and free of any defenses to the underlying contract. The confirmed debt obligations provide a better source of working capital for the participants, or can be converted into electronic promissory notes. The system provides an electronic exchange for electronic promissory notes, allowing participants to raise working capital in various ways, for example, by selling them.
