  • Patent number: 11958457
    Abstract: A military vehicle includes a passenger capsule having a front end and a rear end, a front module coupled to the front end of the passenger capsule, a rear module coupled to the rear end of the passenger capsule, a generator, and an export power kit. The front module includes a front subframe, a prime mover, a front axle assembly, and a front differential coupled to the front axle assembly. The rear module includes a rear subframe, a rear axle assembly, and a transaxle coupled to the rear axle assembly, the prime mover, and the front differential. The generator is configured to be driven by the prime mover to generate electricity. The export power kit is coupled to the generator and configured to facilitate exporting power off of the military vehicle.

  • Patent number: 10281343
    Abstract: The present subject matter discloses a method of measuring a peak load, including the steps of placing an indenter between a first surface and a second surface, exerting a load on at least one of the first and second surfaces, measuring at least one of a width, depth, radial chord length, and cross-sectional area of an indentation formed by the indenter in at least one of the first and second surfaces; and converting the measured parameter into a load value. Certain methods further include the steps of converting the measured parameter into a load per length value and obtaining a load value by integrating along a circumferential length of the indentation. In still other methods, the exerted load is a compressive load.

  • Patent number: 8609023
    Abstract: A method and apparatus for an automated biological reaction system is provided. In the processing of a biological reaction system, there is a need for consistently placing an amount of liquid on a slide. In order to accomplish this, several methods are used including a consistency pulse and a volume adjust means. Moreover, in order to reliably operate an automated biological reaction system, the dispenser must be reliable, easy to assemble and accurate. Among other things, in order to accomplish this, the dispense chamber is substantially in line with the reservoir chamber, the reservoir chamber piston is removed, and the flow of liquid through the dispenser is simplified. Further, in order to operate the automated biological reaction system more reliably, the system is designed in modular pieces with higher functions performed by a host device and the execution of the staining operations performed by remote devices.

  • Patent number: 8147773
    Abstract: A fluid dispenser useful in automated biological reaction systems comprising a barrel having a reservoir chamber, the barrel having an upper portion and a lower portion, a cap located on top of the upper portion of the barrel and connected to the reservoir chamber, the cap having an external surface with at least one hole therethrough, a valve comprising a biasing member and a hole sealer, the valve being located in the hole in the cap at the point where a downward force is applied against the cap, a coupler having a dispense chamber, the coupler being coaxial with the barrel and wherein the barrel lower portion moves into the dispense chamber during dispensing of fluid, and a vent located between the cap and the reservoir chamber, the vent including a vent opening and a vent material composed of oliophobic material.

  • Patent number: 7516749
    Abstract: Methods of and apparatus for washing an array of sites in high-density microplates or similar assay plates wherein the microplates or assay plates are washed in an inverted or nearly inverted position, rather than in an upright position. Preferably, the wash liquid is dispensed upwardly in the form of a sheet from a nozzle mounted on a spray bar as the spray bar moves relative to the microplate or assay plate. After washing, the microplate or assay plate is dried with a stream of gas such as air, also preferably blown upwardly in the form of a sheet.
