摘要:
A reach back secure communications terminal includes an easily removed and secured personality faceplate including an encryption device. The personality faceplate removes the encryption device from the reach back secure communications terminal, while leaving behind non-secure portions of the reach back secure communications terminal. This feature is most advantageous in emergency situations where a user needs to evacuate an area quickly, without the need to have to disconnect and carry in a secure manner the entire reach-back terminal. Because the personality faceplate with the encryption device attached is smaller than the entire reach-back terminal, it is more easily physically secured once removed.
摘要:
A reach back secure communications terminal includes a modem to satellite interconnect board that captures DTMF tones, demodulates encrypted modem information, and converts both into an ASCII string for presentation to a data port of a satellite phone, allowing out-of-band control of a non-secure satellite system (e.g., AT command control of a data port) by a user on a secure side of an encryption device, by including the ability to interpret control signals and control the satellite system appropriately. A false dial tone is presented to the encryption device, and the data stream coming from the encryption device is monitored for the presence of dual-tone, multi-frequency (DTMF) tones representing control signals, the DTMF tones are converted to ASCII characters, which are in turn received as control signals by the satellite phone, allowing control of the functions of the satellite system directly from the secure side of the encryption device.

Asphalt compositions and methods of forming such are described herein. The asphalt compositions and methods of forming such are generally adapted to enable open air processing while producing asphalt compositions that exhibit properties capable of meeting SUPERPAVE™ specifications.
摘要:
A system and method is provided for automatically identifying and removing malicious data packets, such as denial-of-service (DoS) packets, in an intermediate network node before the packets can be forwarded to a central processing unit (CPU) in the node. The CPU's processing bandwidth is therefore not consumed identifying and removing the malicious packets from the system memory. As such, processing of the malicious packets is essentially “off-loaded” from the CPU, thereby enabling the CPU to process non-malicious packets in a more efficient manner. Unlike prior implementations, the invention identifies malicious packets having complex encapsulations that can not be identified using traditional techniques, such as ternary content addressable memories (TCAM) or lookup tables.

Phosphonate substituted compounds with HIV protease inhibitory properties having use as therapeutics and for other industrial purposes are disclosed. The compositions inhibit HIV protease activity and/or are useful therapeutically for the treatment of AIDS and other antiviral infections, as well as in assays for the detection of HIV protease.
摘要:
In methods of preparing asphalt including asphalt/elastomeric polymer compositions, it has been discovered that the emission or evolution of H2S can be reduced by adding certain H2S scavengers to the asphalt mixture, but that not every known H2S scavenger can be effective in this method. Particularly helpful H2S scavengers include inorganic metal salts. Suitable inorganic or organic metal salt H2S scavengers include, but are not necessarily limited to those where the metal of the salt is zinc, cadmium, mercury, copper, silver, nickel, platinum, iron, or magnesium, and mixtures of these salts.

摘要:
An auger/cut off assembly for a floating screed asphalt paver. The auger/cut off assembly consists of an auger mechanism with an axis of rotation and a cut off mechanism. The cut off mechanism has a concave cut off panel that rotates about the axis of the auger mechanism from an open strike off position to a closed cut off position. Because the concave cut off panel closely conforms to a portion of the circumference of the auger mechanism, the cut off mechanism provides for low ground clearance. The concave cut off panel serves the dual function of striking off the paving material when in the open strike off position and cutting off the deposit of paving material when in the closed cut off position.

摘要:
A dispenser for dispensing foamable compositions includes a first module comprising a first housing, a fluid flow fitting in the first housing, a shutoff valve in the first housing and in fluid communication with the fluid flow fitting. The dispenser further includes a second module comprising: a second housing, a valving chamber in the second housing for receiving fluid from the shutoff valve and the fluid flow fitting; and an attachment for securing the first and second modules to one another with the valving chamber in fluid communication with the shutoff valve and the fluid flow fitting so that foam precursors can travel from the foam fittings to the valving chamber, and be dispensed from the chamber to form foam.
