Abstract:
Optical cubes and optical cube assemblies for directing optical beams are provided. The optical cubes are optically transparent modules that can be adapted to reflect, transmit, and/or partially reflect and transmit optical beams. The optical cubes may include bi-direction or multi-direction beam directing elements for directing optical beams. The optical cube assemblies may include flexible chip assemblies attached to optical cubes. The chip assemblies may include vertical cavity surface-emitting lasers for emitting optical beams or receivers for receiving optical beams mounted on a flexible and electrical interconnect mounting assembly.
Abstract:
Methods for the detection and/or quantification of a biological material in a sample. The method includes the steps of liquefying the sample (if necessary) and pouring the liquefied sample into the incubation vessel. The incubation vessel has a generally flat horizontal surface and the surface is divided into at least one incubation site. Each incubation site is adapted to hold an aliquot of liquid and is sized and shaped, and formed of a suitable material, to hold the aliquot within the well by surface tension. Any excess liquid from the liquefied sample is poured from the surface of the incubation vessel. The method then involves incubating that incubation vessel until the presence or absence of the biological material is determined. The presence of air bubbles can be dramatically reduced by the presence of a surface acting agent in the liquid sample deposited on the device surface. Such an agent can be added to the sterile diluent used to prepare the test reagent, can be separately added to the test reagent after it is prepared, or can be added to the test sample directly while it is being prepared for testing.
Abstract:
A retaining clip for retaining reagent test slides in a stacked arrangement includes a first assembly having a first cover plate and at least two parallel, co-planar rails extending transversely from an inner surface of the first cover plate. A second assembly includes a second cover plate, and a rail receiving platform extending transversely from an inner surface of the second cover plate. The first cover plate and the second cover plate define between them a space for receiving the plurality of reagent test slides. The rails of the first assembly include ratchet teeth, and the rail receiving platform of the second assembly includes pawls. The pawls engage the ratchet teeth to prevent the separation of the first assembly and the second assembly and to securely but removably hold the plurality of reagent test slides in a stacked arrangement between the first and second cover plates.
Abstract:
The current invention provides a method of attaching a plurality of cores wherein a core has a via with a conductive surface to be electrically connected to a conductive surface on another core. The method provides for applying a metallurgical paste to a conductive surface, removing a portion of the flux from the paste and joining the two cores. The current invention also provides a structure including a plurality of cores wherein a metallurgical paste electrically connects a via with a conductive surface on a core to a conductive surface on another core.
