Abstract: A skid (700) for use in separating biocomponents includes a housing (701) bounding a compartment (708), the compartment being partially bounding by a mounting platform (709); and a loading assembly (800) secured to the housing so as to communicate with the compartment.

Abstract: Known operator housings include a vertical groove in an internal bore adapted for engagement with a roller. Over time the groove will fail as the roller exits the groove resulting in a gouge in the internal bore. Operator housings are disclosed in which a recess is disposed in the internal bore of the operator housing. The recess is adapted to receive a removable, arcuate-shaped insert. The insert may include a groove section adapted for longitudinal alignment with the groove in the internal bore of the operator housing. The groove section will be located within the internal bore such that the roller will exit the groove section of the insert. If the roller causes damage, it will be to the insert, not to the operator housing. If such damage occurs, the damaged insert can be removed and replaced with a new insert. This avoids scrapping or refurbishing damaged operator housing.

Abstract: Techniques regarding nanofluidic chips with a plurality of inlets and/or outlets in fluid communication with one or more nanoDLD arrays are provided. For example, one or more embodiments described herein can comprise a nanoscale deterministic lateral displacement array between and in fluid communication with a global inlet and a global outlet. The nanoscale deterministic lateral displacement array can further be between and in fluid communication with a local inlet and a local outlet. Also, the nanoscale deterministic lateral displacement array can laterally displace a particle comprised within a sample fluid supplied from the global inlet to a collection region that directs the particle to the local outlet. An advantage of such an apparatus can be the expanded versatility of the nanoscale deterministic lateral displacement array for sample preparation applications involving nanoparticles not accessible to other higher throughput microscale microfluidic technologies.

Abstract: Improved valve seal and integrity systems and methods are disclosed. Pressure in an internal cavity of a valve may be monitored and stored to assist in determining whether one or more seals in the valve are leaking. Internal cavity temperature may also be recorded and monitored to assist in determining whether there are any valve seal leaks. Expected pressure corresponding to a detected internal cavity pressure (that may be determined by correlating temperature and known fluid properties) may be compared to detected internal cavity pressure to assist in determining the existence of valve leaks. Internal cavity pressures and pressure differentials over time may be used to determine remaining valve seal life, leak severity, and/or integrity of a check valve on the valve. Indications of seal life, leak severity, seal integrity, and/or check valve integrity may be displayed to an end user or otherwise provided to a database or computer.

Abstract: High-accuracy locating systems and methods are used for determining successful caregiver rounding, monitoring whether housekeepers have properly cleaned patient beds, or determining whether patients have ambulated sufficient distances during recovery. Patient beds having at least two locating tags are used for establishing patient care zones around the patient beds. Locating anchors and equipment tags are moved around a patient room to determine optimum locating anchor placement within the patient room based on signal quality values. A locating tag on a patient bed switches roles to operate as a locating anchor in response to the patient bed becoming stationary. A locating tag has a digital compass which is used to determine a field of good ranging relative to a front of a caregiver wearing the locating tag.
