Abstract: This is a system and method for network surveillance and detection of attempted intrusions, or intrusions, into the network and into computers connected to the network. The System functions are: (A) intrusion detection monitoring, (B) real-time alert, (C) logging of potential unauthorized activity, and (D) incident progress analysis and reporting. Upon detection of any attempts to intrude, the System will initiate a log of all activity between the computer elements involved and send an alert to a monitoring console. When a log is initiated, the network continues to be monitored by a primary surveillance system. A secondary monitoring process is started which interrogates the activity log in real-time and sends additional alerts reporting the progress of the suspected intruder.

Abstract: A method and apparatus for stopping the operation of a failed device and preventing that device from being turned back on is shown, using two thresholds, a first failure threshold is shown when the device may be turned off or prevented from further operation. A second safe operation threshold is shown, different from the first threshold and within the safe operation range of the device. As the temperature rises, this transistor is driven further to conduction diverting base current from a second transistor and driving it further into nonconduction. The collector current from the second transistor is diverted to a resistor providing additional bias to the temperature sensitive transistor and driving it to a new bias. This bias establishes the second threshold. According to the inventive principles, the device is prevented from being turned back on until the safe operating threshold is reached.

Abstract: An IC is constructed with deep layers preventing current flow due to parasitic transistors formed within the IC. Reverse current in case of voltage source polarity reversal is prevented by means of the reverse bias diodes formed by the addition of a P+ ring, and N+ well, for the embodiment disclosed.

Abstract: A set of series connected power supplies are progressively connected to a load as the voltage to the load increases. Starting with a first voltage power supply, as the load voltage increases at or to the first voltage level, a switch connects the next successive power supply in series with the first power supply and to the load. As the load voltage increases progressively approaching each successively connected power supply in the set of series connected power supplies, the load is switched to the next series connected power supply increasing the voltage and current available to the load. As the load voltage decreases progressively from the highest series connected voltage to the voltage of the next lower series connected power supply voltage, the load is switched to that next lower series connected power supply. In operation, a first power supply is connected in series to a plurality of power supplies. A switch connects the first power supply to a load.

Abstract: A differential voltage monitor is shown using a resistive bridge to produce a sample value representing that differential voltage. A portion of the resistive bridge is located on an IC and a portion is external to the IC. The object is to compare the differential voltage with a reference, producing a logic signal at a threshold level. The threshold level serving as a reference and the sample valve representing the differential voltage are made to be equally dependent on the bridge components located on the IC. In this way, any changes in the IC located bridge resistors compared to the bridge resistors located outside the IC are prevented from affecting the measurement.

Abstract: An SCR clamp provides a low impedance discharge path for static charges across on IC's pins. The SCR clamp cathode, cathode, gate anode, and anode gate float when the protected IC is disconnected from its associated circuit elements. Under this condition, the SCR clamp can be turned on at the low Vh and Ih levels of the SCR, allowing the clamp to operate to discharge static electricity at the low voltage determined by SCR junction biases.

Abstract: A dual discharge network is shown discharging any residual charge on the gates of MOSFET's used to protect a device from over voltages. The dual discharge networks are separately responsive to a positive or negative voltage at an input terminal such as an I/O input terminal, for example. Bias to each of the discharge networks is provided by the positive or negative I/O voltage and power to the transistors within each discharge network is provided by the MOSFET gate charges. In this way, a conduction path is formed between the positively and negatively charged MOSFET gates driving the gates towards ground, driving the MOSFETs to non-conduction and isolating a protected device from a I/O over-voltage where positive or negative.

Abstract: The cavities of IC's are inspected for contaminants rising a point source x-ray. The IC's are arranged on a curved surface, approximating the arc formed by the radiation from the point source x-ray. In this way, the IC's may be stood on end with the sides parallel to the x-ray radiation. In this arrangement, the radiation from the x-ray point source passes approximately parallel to the IC size and a clear image of the cavity is achieved without distortion produced by the x-rays passing thou the bottom or the top. Alternately, the curved surface for mounting the IC's may be formed of small straight sections formed at angles approximating the curve.

Abstract: A method and apparatus is shown for holding callers in a queue for the broadcast of a message. Callers are assembled by a common attribute such as a caller I.D. The callers are assembled in a queue according to this attribute and according to a suitable priority process. Once the callers are assembled into a set, the priority process has been completed, then all of the callers within the set are connected to receive the same broadcasted message.

Abstract: A transistor built on a substrate employs two collectors, an output collector and a secondary collector. The purpose of the secondary collector is to collect minority carriers at saturation and feed these minority carriers back to the input reference of a current mirror. This saturation current causes a decrease in the current through the input reference transistor and decreases the current in the output of the current mirror responsively, driving it away from saturation.

Abstract: A switch provides time multiplex connections between ports in a telephone system. These connections are organized according to protocols located in software programs on an Integrated Multi-Protocol Processing unit (IMP). IMP includes several processing systems for processing the several protocols received by the telephone switch. Each of these IMP's then processes the respective protocol to produce switching control information. This switching control information is then transmitted to the telephone switch on a separate communications channel. The switch then uses this process protocol information to establish and remove telephone connections, according to the particular protocol received.

Abstract: A gas phase plasma cleaning method and apparatus is shown for removing contaminants from the surface of exposed metallic parts on integrated circuits (IC's). A two step method is shown using a defined gas mixture of argon and oxygen, and ammonia and hydrogen. The gases are separately introduced into a plasma chamber. The argon oxygen mixture is used to remove carbonatious material by chemical reaction and by milling. The ammonia hydrogen mixture is introduced to chemically remove and reduce oxides and phosphates. Surface energies are increased to permit improved adhesion of inks. Additionally, intermediate oxides formed after the plasma exposure prevent complete regrowth of the normally passivating oxide layer.

Abstract: A current rise in fall time limited voltage follow is shown having a voltage driver providing a voltage signal into a current driver. The output of the current driver is a load varying in resistance, for example, as the number or combination of devices connected to the load vary. The maximum current into the load and the maximum rise time of the current into the load is limited at the output of the current driver to a maximum by the input impedance of the current driver. The rise time and the current into the load may increase until the resistance of the load is substantially that of the current driver input resistance reduced by a factor of N. The factor N is the maximum current capability of the output of the current driver related to the current driver input current generated by the voltage signal from the voltage driver.

Abstract: In a digital radio system, data is transmitted in packet form. A check or parity bit is used to determine whether any errors have occurred between data transmission and demodulation. That same check bit is used to identify its location in a packet. From that check bit location, it is then possible to identify the starting and ending data bits in a packet and to correctly interpret the packet data.

Abstract: Within an ion implanter, a source element or filament may be cured outside of the ion implanter. This may be accomplished within a vacuum chamber using the same source assembly or canister to hold the filament as is used within the ion implanter. The filament within the source canister is inserted into the vacuum chamber and a vacuum is produced at a first set point. Then, the current is gradually increased while monitoring the pressure compared to a second set point. The current is decreased where the second pressure set point is reached to prevent oxidation. Where the chamber pressure is below the second set point, the current is allowed to increase. The curing of the filament is indicated when the filament increases to the third set point, without chamber pressure exceeding the second set point.

Abstract: A wideband detector having a substantially flat response is made by using the signal at the isolation port of a coupler. As the response or transfer characteristic at the isolation port is substantially linear, a matching network having the inverse opposite transfer characteristic with respect to frequency may be connected to the coupler. The addition of the matching network transfer characteristic to the transfer characteristic of the coupler in the isolation port produces a superposition. Accordingly, the matching network transfer characteristic compensates for the linear varying transfer characteristic at the coupler isolation port to produce a substantially flat output of the matching network. The detector connected to the matching network output will then produce a detector signal which is substantially flat over the frequency range of the bandspread of interest.

Abstract: A formable or deformable material is pressed into place and in contact with the leads connected to semiconductor device. A connection is made through a snap or other device to ground or to some other suitable connection. With the deformable material in place, any static electricity appearing on the semiconductor device is dispersed to ground. In this way, static electricity building on a semiconductor device is prevented from being transferred to other connected devices and injury to those devices. The deformable material is electrically conductive and makes contact by being pressed into place around, or on to, exposed contact leads.

Abstract: A data transmission network includes circulating loops designed to increase the reliability of the network and its transmission speed. Redundant transmission within the circulating loops is sensed and terminated. This is accomplished by identifying those stations serving as an entrance port to a circulating loop within the network. When a transmission of information is received at that station, it is marked with that station's address. The information is sent into the network including into the circulating loop. As the circulating loop leads back to itself, that transmission is received at the same entrance station which transmitted it into the circulating loop. Upon receipt, the entrance station recognizes its own address and terminates any further transmission.
