摘要:
A sample tray carrying a two-dimensional array of sample tubes for analyses by an instrument. Tabs on the side of the tray inform the instrument as to the location of the rows of sample tubes within the tray. A short wide rack gear followed by two long thin rack gears cooperate with a pinion gear on the instrument to move the sample tray along a channel established by the instrument. The wide short rack gear serves to properly orient the tray in the instrument's channel. A C-hook at the rear of one tray can engage a T-tab at the front of a following tray to couple the two trays together. The coupling components do not extend below the upper half of the tray to assist the operator when coupling two trays together. Overhanging rack gear segments between the two coupled trays allow for their continuous propulsion by the instrument's cooperating pinion gear. The tray may take the form of a hollow shell into which fit holders providing the actual locations for the sample tubes. The holder may have a composition of plastic, cardboard, or styrofoam. Alternatively, the tray may have a nonremovable holder and operate as a solid unit.

Providing a network address is disclosed. A communication indicating that a first node desires to communicate via a packet data network with a second node configured to provide access to a private resource is received. A non-publicly advertised packet data network address usable to communicate with the second node via the packet data network is provided to the first node.

A method of operation of a call center system includes: providing a commissioning terminal in a first locale; providing a hardware device coupled to the commissioning terminal; provisioning a first locale controller from the hardware device by the commissioning terminal; and managing an inter-locale gateway, by the first locale controller, for commissioning a second gateway in a second locale.

A method of operation of a call center system includes: providing an operator console having a first interface port and a second interface port; communicating with a local controller, having a primary interface port and a secondary interface port, by the operator console; establishing a redundant communication mode between the operator console and the local controller; and transmitting redundant messages between the operator console and the local controller including transmitting transmission headers having identical content on the first interface port and the second interface port.
摘要:
Mobile communication data received at the sending based transceiver station via a radio frequency transmission is received a packet data network from a sending base transceiver station. The mobile communication data is forwarded to a base station controller via an interface defined at least in part by a third party base station controller vendor.

An axial fan assembly includes a hub, a plurality of connection structures, and a plurality of isolated members. The hub is rotatable about an axis of rotation and includes a radially extending face and a cylindrical portion extending axially from the face. The face includes a radially inner face portion and a radially outer face portion. The plurality of connection structures extends radially inwardly from the radially outer face portion and extends radially outward from the radially inner face portion. The plurality of isolated members extends radially outwardly from the radially inner face portion and is isolated from the plurality of connection structures and from the radially outer face portion by a plurality of slots.

A sports swing exercise device composed of a weight attached to a shaft by means of a spring. When the shaft is swung, the muscles used in the swing are not only strengthened with repeat use, they are stretched toward full articulation with the spring as it eases the transition of momentum and inertia at the ends of the swing from one direction to its opposite.

A reference cell simulating the light amplitude spectrum of an alpha scintillation cell containing radon.sup.222. The cell includes a gas-tight container having a transparent window. The interior of the container, aside from the window, has a coating of a luminescent material. Inside of the container lies an amount of radium.sup.226. The radium radioactively decays to produce alpha particles and radon.sup.222. The radon.sup.222 and its daughter particles also undergo radioactive decay to produce further alpha particles. The 1620-year half life of the radium.sup.226 assures an adequate supply of the radon.sup.222 for a greater time period than radon's 3.825-day half life. The production rate of the alpha particles within the container increases for a period of approximately 22 years after the cell's construction. Although the radium.sup.226 generally has a nonuniform distribution in the cell, the produced radon assumes a gaseous form and uniformly diffuses throughout the entire cell. The decay products of the radon.sup.222 return to the solid state and deposit uniformly on the cell's walls. The cell may allow the alpha particles from the radium.sup.226 to contact the luminescent material and produce light. Alternately, the cell may prevent the utilization of these alpha particles by interposing a barricade between the radium and the luminescent material. Making the cell involves coating the inside of the container with luminescent material while leaving the window clear. After placing the radium.sup.226 inside, the cell undergoes permanent sealing against the ingress or egress of gaseous components.
