  • Patent number: 8327950
    Abstract: An excavation apparatus includes a base structure mountable to a vehicle, and a first supporting member pivotally coupled to the base structure. The first supporting member is pivotable about a pivot axis that is generally parallel to a lateral direction between a retracted position and an advanced position. A second supporting member is rotatably coupled to the first supporting member. A rotary spindle is supported by the second supporting member and extends lengthwise along a cutting axis and is rotatable thereabout for driving a cutting element. When the first supporting member is in the advanced position, the second supporting member is rotatable about a rotation axis that is generally parallel to a longitudinal direction between a stowed position in which the cutting axis is generally parallel to the lateral direction and a deployed position in which the cutting axis is generally parallel to a vertical direction.

  • Patent number: 8326931
    Abstract: Embodiments of the systems and methods described herein facilitate the transmitting, receiving, and processing of encoded messages wherein the header fields in the message header are protected. In one embodiment, the contents of the header fields to be protected are inserted into the message body as one or more additional lines of text, for example, prior to encoding and transmitting the message to a message recipient. Upon receipt of the message, the message recipient processes the encoded message such that the contents of the protected header fields can be extracted from the message body. Accordingly, by inserting the contents of the header fields to be protected into the message body, the header fields may be protected using existing standards and protocols for facilitating secure message communication.
