Abstract:
A mail tub in the form of a substantially rigid container and a removable lid which seals the container. The container includes an air inlet port and an air outlet port for sampling air in the mail tub for possible biological contamination, such as anthrax. The container includes structure along the bottom and walls to prevent mail from contacting the walls and bottom. Such structure, in one embodiment, may include raised standoffs along the bottom of the container and channels along the walls to facilitate airflow efficiency through the mail tub when the lid is attached and an air pressure source is applied to the one of the ports. Air samples of the sealed container air are collected for contamination analysis.
Abstract:
This invention provides a mechanism for receiving flat articles, such as mail, moving in a travel path with a substantially horizontal orientation and for dropping selected such articles into either a single receptacle positioned below the mechanism or into a plurality of receptacles spaced along the length of the travel path, while maintaining the substantially horizontal article orientation for all such articles. The mechanism includes a holding station for each receptacle into which each article to be dropped is initially deposited, the holding station being just below the travel path, a retractable floor for the holding station and a driver selectively operable for rapidly retracting the floor in a substantially horizontal direction to permit articles accumulated in the holding station to drop substantially vertically into the corresponding receptacle. The driver may be activated in response to the holding station being filled by a selected amount. Where there are plurality of holding stations, a separate driver may be provided for each, or two or more of the holding stations may be operated by a single driver.
Abstract:
A conveyor or article transportation system for conveying or transporting, for example, pieces or units of mail, or similar flat articles, has a pair of guide fingers operatively extending downstream from a downstream end of the conveyor so as to project into a stacking chamber within which the pieces or units of mail, or flat articles, are to be stacked. The guide fingers effectively vertically support the downstream end portions of the pieces or units of mail, or articles, such that the downstream end portions of the mail or articles do not curl or curve downwardly, or sag, whereby the pieces of mail or articles are deposited within the stacking chamber in a substantially flat state so as to prevent rollover of the pieces of mail or articles which would otherwise become jammed within the stacking system and cause upstream jamming or interruptions within the conveying system. In addition, the prevention of the curling or rollover of the pieces of mail or articles, in turn, prevents the pieces or articles from being stacked partially inside each other and therefore out of their previously sorted serial sequence.
Abstract:
A flat article conveyor system comprises a forming wheel which is provided for operative cooperation with a grooved roller whereby a relatively shallow and temporary longitudinal crease, rib, or spine is formed or impressed within relatively thin pieces or units of mail, or similar flat articles, as the pieces or units of mail, or similar flat articles, are conveyed so as to effectively reinforce the piece or unit of mail, or similar article, such that the piece or unit of mail will not experience curl or sag so as not to subsequently rollover when, for example, the particular piece or unit of mail, or similar flat article, is being released from a conveyor mechanism into a stacking or similar accumulation chamber.
Abstract:
A blast energy mitigation structure may employ a V-shaped hull to decrease the pressure wave imparted to a vehicle during a blast event, and/or an energy absorbing structure to absorb a portion of the blast force, thereby minimizing the forces and accelerations experienced by passengers in the vehicle and consequently reducing their injuries and increasing their survivability during a blast event. An exemplary blast energy mitigation structure may have a V-shaped hull and an energy absorbing structure incorporated into the chassis of a vehicle such as a Tactical Wheeled Vehicle, the energy absorbing structure comprising a truss-like structure including I-beams.
Abstract:
A process for determining a center of gravity of a vehicle having a sprung portion and an unsprung portion on the basis of selective variation of a lateral and a longitudinal orientation of the sprung portion relative to the unsprung portion.
Abstract:
A system and method for vehicle mobility traction/ride control. The system includes a mode controller configured to output control signals to a variety of vehicle control subsystems in response to operator mode selection input.

Abstract:
A system and method for substantially eliminating the release of pathogen agents circulating in the air within a collection box. The mail deposit openings (12, 14) of a collection box mail chute (16) are adapted with gaskets (18, 20) to form an airtight seal when the mail chute (16) is opened and closed, thereby isolating the collection box interior (26). An alternative embodiment can further include a charging device (32) and a chargeable material (34) to attract and detain airborne and free pathogen particles that enter the mail chute passage (22) either by newly deposited mail pieces (38) or airborne pathogen particles that migrated from within the collection box collection area (26).
Abstract:
A mail processing apparatus, includes an enclosure adapted for receiving deposited mail articles, a depository port adapted for passing deposited mail articles into the enclosure, and a sealing apparatus operatively associated with the depository port and adapted to seal deposited mail articles that pass through the depository port. The sealing apparatus may be a laminator adapted to apply a layer of plastic material to opposing sides of deposited mail articles.
