摘要:
An insert device and co-culture device assembly incorporating the insert device, which includes an insert chamber with two fluid impermeable side walls that extend from a microporous bottom to an open top to form an inner cavity. The first side wall is shaped to form a convex arc that follows between about half of a circumference of the well and less than an entire circumference of the well. The second side wall joins ends of the first side wall and protrudes inward towards a center of the convex arc. A flange extends outward from or beneath the top and is notched to form a gap adjacent to the second side wall, which forms an access port allowing access to the lower chamber with a micropipette tip when the insert device is inserted into a well of a single or multi-well plate.

A trailer wiring connector to provide mating to a trailer-side wiring harness. The trailer wiring connector includes a plug and a freely rotatable nut. The plug is configured to electrically communicate with electrical systems of a trailer. The freely rotatable nut is movably surrounding the plug and configured to mate with a trailer wiring connector assembly. At least two projections are disposed on the plug and preventing the freely rotatable nut from being removed.

A method of operating a single-tuner radio includes tuning into a first frequency. A pause in a first signal associated with the first frequency is detected. Tuning is switched from the first frequency to a second frequency. A signal quality metric for the second frequency is measured. Tuning is switched from the second frequency to the first frequency.

A method of performing alternate frequency switching in a radio includes tuning the radio to a primary frequency. A candidate alternate frequency is identified. It is determined whether the candidate alternate frequency is a third order inter-modulation artifact. Tuning is switched from the primary frequency to the candidate alternate frequency only if it is determined in the determining step that the candidate alternate frequency is not a third order inter-modulation artifact.

A modular container has identically molded sides pieces connected together at corner joints and separately molded, identical top/bottom pieces. The corner joints are formed by snap fit engagement of flexible locking tabs of one side piece with pockets on another side piece when the molded side pieces are serially connected together. The flexible locking tabs are biased oppositely to one another in alternating manner and each tab engages with a shoulder in the corresponding pocket to enable a zipper effect with respect to the assembly and disassembly of the corner joints. Two top/bottom pieces are secured by relative rotation to the assembled side pieces to form the container. An extension ring or divider can be used between upper and lower sets of the assembled side pieces to enable different container sizes. The component parts are molded with a degree of flexibility that enhances the assembly/disassembly of the corner joints.

A method of operating a single-tuner radio includes tuning into a first frequency. A pause in a first signal associated with the first frequency is detected. Tuning is switched from the first frequency to a second frequency during the pause. Fieldstrength, multipath, adjacent channel energy, frequency offset and FM modulation for the second frequency are measured. Tuning is switched from the second frequency to the first frequency. Tuning is switched from the first frequency to the second frequency dependent upon the measuring step.

The present invention relates to a support block and a system for roof cooling. The support block supports a pipe above a structure, wherein the pipe has a cross sectional area and a diameter of predetermined dimensions, and the support block includes a number of outer surfaces each having an opening and a cavity. Each cavity has a cross sectional area larger than the cross sectional area of a pipe and the opening can be less than the diameter of the cavity cross sectional area or slightly less than the diameter of a pipe. Dovetail notches on the surfaces of the support block are present to attach the support block onto the roof. Adhesives can be used in the dovetail notches or an adaptor plate attached to the roof can be used to attach the support block to the adaptor plate. Alternatively, the support block can be used to assist in supporting and routing any type of conduit or cabling.

A method and apparatus for cleaning dust and particulate from automated mail processing equipment having a conveyer disposed along a plurality of processing stations is provided. The cleaning system includes at least one air nozzle disposed at each station and at least one vacuum port disposed at each station and spaced apart from the air nozzle. A vacuum for creating a vacuum at the vacuum port and an air source for directing air through the air nozzle is provided. A sequencer for allowing air to sequentially pass through the air nozzle at each station while a vacuum is created at the same station is provided. A controller in communication with the sequencer is provided for relaying sequencing information to the sequencer.
