Automated unpacking of executables packed by multiple layers of arbitrary packers
The packing manager provides an automated method that allows existing AV scanning technology to be applied to detect known malware samples packed by one or more packers that are potentially proprietary. The packing manager tracks the memory areas to which an executable binary writes and executes, and so can unpack programs packed by multiple arbitrary packers without requiring reverse-engineering of the packers or any human intervention. By tracking page modification and execution of an executable binary at run time, the packing control module can detect the instant at which the program's control is first transferred to a page whose content is dynamically generated, so AV scanning can then be invoked. Thus, code cannot be executed under the packing control manager without being scanned by an AV scanner first. |

Surgical robot and robotic controller
The present invention was developed by a neurosurgeon and seeks to mimic the results of primate neurological research which is indicative of a human's actual neurological control structures and logic. Specifically, the motor proprioceptive and tactile neurophysiology functioning of the surgeon's hands and internal hand control system from the muscular level through the intrafusal fiber system of the neural network is considered in creating the robot and method of operation of the present invention. Therefore, the surgery is not slowed down as in the art, because the surgeon is in conscious and subconscious natural agreement and harmonization with the robotically actuated surgical instruments based on neurological mimicking of the surgeon's behavior with the functioning of the robot. Therefore, the robot can enhance the surgeon's humanly limited senses while not introducing disruptive variables to the surgeon's naturally occurring operation of his neurophysiology. This is therefore also a new field, neurophysiological symbiotic robotics. |

Apparatus and method for implementing a suspend mode in an ethernet-based communications system
The present invention describes a communications system having a first link partner and a second link partner that are connected by a communications link having at least four pairs of conductors. According to IEEE Standard 802.3 (e.g. Ethernet) for 1000Base-T, a data link is maintained (in a period absent data transmission) by sending idle signals over four pairs of conductors of the cable to maintain a logical connection. This idle signal scheme is replaced with an alternate idle signaling scheme that uses only two pairs of conductors to maintain a logical connection and therefore can operate with using lower power. The other two pairs of conductors of the four pairs of conductors are unused to maintain a logical connection absent data transfer, and therefore can be used to implement a Suspend Mode of operation. During Suspend Mode, the physical layer of each link partner powers down unnecessary circuitry so as to operate in a low power environment. To initiate the Suspend Mode, idle signals are sent on one of the un-used pairs of the conductors mentioned above. To exit Suspend mode, idle signals are sent on respective conductors simultaneously. |

Route optimization for on-demand routing protocols for mesh networks
Various embodiments implement a set of low overhead mechanisms to enable on-demand routing protocols. The on-demand protocols use route accumulation during discovery floods to discover when better paths have become available even if the paths that the protocols are currently using are not broken.
