  • Patent number: 9519000
    Abstract: Systems and methods for processing and analyzing samples are disclosed. The system may process samples, such as biological fluids, using assay cartridges which can be processed at different processing locations. In some cases, the system can be used for PCR processing. The different processing locations may include a preparation location where samples can be prepared and an analysis location where samples can be analyzed. To assist with the preparation of samples, the system may also include a number of processing stations which may include processing lanes. During the analysis of samples, in some cases, thermal cycler modules and an appropriate optical detection system can be used to detect the presence or absence of certain nucleic acid sequences in the samples. The system can be used to accurately and rapidly process samples.

  • Patent number: 8118042
    Abstract: The present invention concerns an improved apparatus for cleaning the interior of a liquid handling probe to reduce the amount time and the volume of wash fluid required to clean the probe and minimize carryover of material between different samples. In addition to the probe, the apparatus includes one or more wash fluid reservoirs, a compressed gas supply, one or more pumps, two or more valve-controlled probe lines and a controller for opening and closing the valves and actuating the pump(s) at desired time intervals. The invention further concerns a method of cleaning a liquid handling probe using the claimed apparatus and comprising sequential steps of pumping wash fluid and compressed gas through the probe.

  • Patent number: 6548982
    Abstract: A robotic vehicle capable of traveling over various terrain and traversing obstacles. In one embodiment, the vehicle includes a cylindrical body having two or more drive wheels coupled to the ends thereof. The wheels are selectively powered to propel the vehicle. The vehicle may further include a spring member which may be deflected to a first, stored position from a second, extended position. The spring member may be quickly released from the first, stored position such that it strikes the terrain with sufficient force to lift and propel the vehicle over or onto a proximate obstacle or object. Robotic vehicles of the present invention may also include one or more sensing devices operable to collect information. Electronics may further permit autonomous, semi-autonomous, and/or remote control of the vehicle. In still other embodiments, the robotic vehicle forms part of a multi-robot surveillance team.
