Abstract:
Disclosed is a redundant braking system for a vehicle. A controller may monitor a status of a hydraulic braking system, and during vehicle travel, automatically switch to a modulated electric braking system which is separate from the hydraulic braking system when the hydraulic braking system fails. The modulated electric braking system may utilize a brake acting on a drive shaft of the vehicle, and an operator-actuated switch may set a mode of the modulated electric braking system to a non-modulated parking brake mode.
Abstract:
A mail box configured to contain and reduce exposure to hazardous particulates, which includes a container having a deposit port at an upper end and a collection chamber at a lower end. There is at least one door at the upper end for mail to be placed into the deposit port. A normally open sealable bag is located in the collection chamber for receiving mail and for being sealed when the mail is to be removed from the container. There is a bag holder constructed and arranged to hold a bag in place and normally open so that in a first position, mail placed into the deposit port falls downwardly through the bag holder and into a bag in the collection chamber and which bag may be preliminarily sealed while in this position, and in a second position, the bag may be more securely sealed and removed from the bag holder. The bag holder is movable from its first position in which the bag is within the collection chamber to the second position in which the bag is outside of the collection chamber and includes two open frames hinged together for removably holding the top of a bag. The bag holder has an upper frame and a lower frame which are arranged so that the top of an open bag may be clamped between the upper and lower frames to hold an open bag in place in the collection chamber.

Abstract:
A mail drop box for isolating mail deposited therein having a closable, removable container inside the box for receiving mail and has an opening in the top. A plurality of mail transmitting chutes each having a deposit port at its upper end and an exit port at its lower end to receive mail through the deposit port and direct such mail into the container. The opening in the removable container is closed when desired to isolate mail from the ambient atmosphere and permit removal of the container without exposing the ambient atmosphere to hazardous particles which may be on or in such mail. A removal door permits removal of the container. A transparent door is adjacent to, but inside of, the removal door for allowing viewing of the opening of the container when the removal door is open.
Abstract:
A rejection rate of a selective sequential processing apparatus such as a mail sortation apparatus is reduced by combining results of at least two feature discrimination arrangements such as optical character recognition and a bar code reader based on comparisons of results of the feature discrimination results against each other and against expected values to validate at least one result and rejecting articles for manual processing only when no feature discrimination result can be validated. The results of one feature discrimination technique can be used to augment results of another feature discrimination technique to improve selective processing accuracy and processing speed and throughput are increased by allowing use of faster or accelerated feature discrimination processes while maintaining a greater number of articles within the automated process.
Abstract:
A drop-box mechanism or system is disposed adjacent to an article conveyor and atop a flat mail storage tub and comprises a platen movable between first and second chambers at which the open top of the storage tub is respectively uncovered and covered. When the platen uncovers the storage tub, deflecting fingers move downwardly so as to cover the platen tracks and the space defined between the bottom of the drop-box mechanism and the open top of the storage tub so as to prevent flat mail articles from becoming jammed within the tracks or from being inadvertently discharged through the space defined between the bottom of the drop-box mechanism and the open top of the storage tub. In this manner, the predetermined conveyed order of articles is preserved so as to facilitate sequence address delivery of the articles to recipients.
Abstract:
A system and method reorients flat articles in a serial stream, by receiving a horizontally moving, serial input stream of substantially vertically oriented flat articles each having a downwardly oriented primary edge, laterally diverting the flat articles in the serial input stream alternately between a pair of separate paths, impeding horizontal movement of each flat article in each separate path, accelerating each flat article with impeded horizontal movement in the direction of its primary edge, and delivering substantially horizontally oriented flat articles from each separate path.
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 method and system for orienting the attitude of a vehicle. The method includes determining a path of travel of the vehicle, determining a slope of the terrain over the path of travel, and adjusting a height of at least one adjustable support of the vehicle.
Abstract:
A mail depository apparatus includes a rigid housing forming a channel adapted for directing deposited mail items and an interface member adapted to attach a flexible container to the housing for receiving deposited mail items from the channel, wherein the interface member is adapted to seal the flexible container to the housing to substantially prevent escape of air from the flexible container and the housing at the interface member.
