摘要:
An apparatus for processing a biological sample is provided. The apparatus includes a body having a processing chamber, a first reservoir, a second reservoir, a filter, a first one-way valve, a second one-way valve, a first fluid pathway, and a second fluid pathway. The first fluid pathway and the second fluid pathway pass through the filter. A method of processing a sample using the apparatus is also provided. The method includes placing a sample comprising a liquid into the processing chamber; urging at least a portion of the liquid through the filter; after urging the at least a portion of the liquid through the filter, urging a portion of a back-flush liquid through the filter into the process chamber to form a first processed sample; and analyzing at least a portion of the first processed sample to detect an indication of a microorganism.
摘要:
A biomedical sensor system. The system can include a sensor adapted to create a signal based on a physiological characteristic from a subject, and a hub adapted to receive the signal from the sensor. The signal can include at least one of an electromagnetic signal, an electrical signal, an acoustic signal, a mechanical signal, a thermal signal, and a chemical signal. The system can further include a connector adapted to couple the sensor and the hub, the connector having a variable length, such that the sensor and the hub can be positioned a variable distance apart by changing the length of the connector. The connector can be adapted to provide a pathway between the sensor and the hub for the signal. A method of applying a biomedical sensor system to a subject can include changing the length of the variable-length connector to provide an appropriate distance between the sensor and the hub, and coupling the sensor to the subject.

A hand-held, manually-operated, sanding tool for use with a replaceable sheet-like abrasive material, such as sandpaper, includes a base member and clamping mechanisms pivotally connected with opposed ends of the base member. The clamping mechanisms include tensioning members arranged to slidably engage angled contact surfaces provided on the ends of the base member opposite the clamping mechanisms to tighten the sheet-like abrasive material as it is installed on the tool.
