Abstract:
A device for performing cell assays has at least one assay site. The site comprises a pair of stimulating electrodes and a cell confinement cavity for confining at least one cell in an extracellular fluid medium. The cell confinement cavity and the stimulating electrodes are arranged so that, in use, each cell is exposable to an electrical field generated by a potential difference applied across the stimulating electrodes. The stimulating electrodes are spaced a distance apart such that the potential difference can induce field stimulation of each cell and simultaneously be below the level that would result in electrolysis of the extracellular fluid medium.
Abstract:
The present disclosure provides a system and method of creating trenches of various widths, including widths that are substantially greater than the width of the boom head or even the chassis. According to the trencher system of the present disclosure, the boom is designed so that it can be easily configured to create a trench of a first width and subsequently create a trench of a second width that is different than the first width.
Abstract:
In a chain excavator including an excavation chain with links routed around a drive sprocket and an end idler with a base plate mounted to a link for supporting excavation implements, a stabilizing element extends rearwardly from directly behind the excavation implement in order to contact and be supported by its trailing base plate.

Abstract:
An excavating apparatus having a prime mover with a longitudinal centerline and a main frame with an engine, a ground drive system and an excavation boom operatively attached thereto wherein the excavation boom has a first end and a second end. The first end of the boom is operatively pivotally attached to the main frame along a main frame pivot axis. The main frame pivot axis is transverse to the longitudinal centerline of the prime mover. A head shaft operatively rotatably attached to the second end of said boom and is operatively pivotally attached to the second end of said boom Also, the excavation drum is mounted onto the head shaft in a manner that the excavation drum cooperates with the excavation chain and a fixed cutter pattern of the excavation chain to stay in consistent alignment with the fixed cutter pattern of the excavation drum.
Abstract:
Information about processes executing on a server together with network traffic and network state information such as ARP and routing tables is collected on each server in a network using a small piece of remote software running on the server. This information is sent to or gathered by a central collating and decoding program, which also obtains information from intervening network devices, such as routing tables, access control lists, load balancer maps and so on. This information is decoded to predict how the network traffic would look at all points in the network.
Abstract:
An interferometer arrangement includes an antenna array that receives radiation from a plane wave emitted by a transmitter, the radiation being incident on the array at an angle (θ). The array includes a plurality of antennas that provide output signals to a switching unit. The switching unit selects pairs of signals and passes them to a processor for processing. The processor is configured to produce an output signal that unambiguously indicates the value of the angle (θ).

Abstract:
An undercarriage having tracks or the like is attached thereto is provided for moving the undercarriage along the ground. A turret is attached to the undercarriage along a first substantially vertical axis so that the turret can rotate. A backhoe is pivotally attached to the turret along a second substantially vertical axis. A trencher is operatively attached to the turret and occupies an area adjacent the undercarriage. Structure is provided for preventing the backhoe from moving into an area occupied by the trencher.
