Abstract: A core drill apparatus includes a swing arm pivotably couplable to a mobile platform and a core drill carried by the swing arm. The core drill being movable via the swing arm between a stowed position and a deployed position with respect to the mobile platform. An excavation rig incorporating the same is also provided.

Abstract: A phased array antenna is disclosed where the transmit/receive modules are replaced by a series of separately packaged components. The components include, for example, a vector control component, a high power amplifier component, a low noise amplifier component, a transmit/receive duplexing component and ancillary supporting components. An advantage of this arrangement is that cheaper antenna arrays can be constructed without limiting the capability and/or performance of a system incorporating such an array when compared to known solutions.

Abstract: This invention relates to utilizing a larger number of lower power transmit/receive modules in a phased antenna array in order to utilize cheaper and simpler transmit/receive modules whilst retaining comparable power per unit area as can be achieved through using conventional high powered transmit/receive modules. The advantage of this arrangement is that cheaper antenna arrays can be constructed without limiting the capability and/or performance of a system incorporating such an array when compared to a conventional solution.

Abstract: A dispenser is provided. The dispenser has a reservoir for storing a liquid or solid material. The dispenser may have a piezoelectric valve or pump located in an opening of the reservoir for regulating dispensing of the material. Alternatively, the dispenser may have a piezoelectric inchworm that directly or indirectly propels the material against or out of the opening. The opening may deposit the material directly or indirectly on the surface of an animal, or under the animal's skin. The dispenser also has means for being attached to the surface of the animal. Alternatively, the dispenser may be placed inside the animal. In certain embodiments, the dispenser comprises a reservoir containing a material to be dispensed, an actuable dispensing element, and an identifying device for remotely communicating information about the dispenser. The dispenser may also include a positioning device adapted to transmit the position of the dispenser.
