  • Patent number: 12383174
    Abstract: A fluid sample optimization device for optimizing a fluid sample includes an inlet, an outlet, a sample path connected between the inlet and the outlet, and a contaminant containment reservoir connected between the inlet and the outlet. The contaminant containment reservoir includes an air permeable fluid resistor proximate the outlet, and is arranged to receive, when a pressure differential is applied between the inlet and the outlet, a first portion of the fluid sample to displace air therein through the air permeable fluid resistor and the outlet, such that upon receipt of the first portion of the fluid sample and containment of the contaminants in the contaminant containment reservoir, subsequent portions of the fluid sample can be conveyed by the sample path from the inlet to the outlet when subsequent pressure differentials are applied between the inlet and the outlet.

  • Patent number: 12388244
    Abstract: The present invention relates to replacing conductors in a high-voltage power transfer system. The method provides, for example, a method for maintaining sections of electrically conductive phases in a direct current (DC) two phase power conductor line, wherein the two phases are parallel and spaced apart. The phases are strung between support structures and supported above the ground. Maintenance work, which include replacement or repair, is performed on sections of the two phases without interrupting a power load in any one of the three phases and without transposing the relative positions of the phases.

  • Publication number: 20250174969
    Abstract: A horizontal conductor lifter includes a main beam to which an elongate wire holder adapter is connected through a horizontal, stacked bank of insulators and an inclined electrically insulating load transfer element collectively forming an electrically insulating truss to temporarily support the weight of a conductor or sub-conductors in a conductor bundle. The wire holder adapter supports vertically oriented wire holders thereon. A rotation actuator acts between the main beam and a distal end of a boom adapter on a crane or truck boom. In use, the rotation actuator, the stacked bank of insulators and the load transfer element prevent rotation of the wire holders to an off-vertical orientation so that the wire holders are maintained in their operative vertical orientation throughout a maintenance operation.

  • Patent number: 12257051
    Abstract: Blood sample optimization systems and methods are described that reduce or eliminate contaminates in collected blood samples, which in turn reduces or eliminates false positive readings in blood cultures or other testing of collected blood samples. A blood sample optimization system can include a blood sequestration device located between a patient needle and a sample needle. The blood sequestration device can include a sequestration chamber for sequestering an initial, potentially contaminated aliquot of blood, and may further include a sampling channel that bypasses the sequestration chamber to convey likely uncontaminated blood between the patient needle and the sample needle after the initial aliquot of blood is sequestered in the sequestration chamber.
