Abstract: An apparatus and technique for applying markings or decorations to the sidewall of a cured tire. A thin polyester carrier sheet has a thermoplastic transfer stock thereon. A heated die is provided having thereon the geometric configuration of the desired marking or decoration. The heated die is urged against the transfer laminate to impinge the transfer stock against the sidewall of the cured tire. The heat of the die effects a release of the transfer stock from the carrier sheet in areas congruent with the indicia carrier by the die. The affinity of the transfer stock for the tire is greater than its affinity for the carrier sheet and the transfer is thus made.

Abstract: In a guidance system for guiding an automated vehicle around an area such as a warehouse, a scanning laser beam from a source mounted on the vehicle impinges upon reflectors located around the area. Each reflector incorporates an optical code which identifies that reflector. Laser light reflected back to the vehicle from the reflectors is used to control the movement and heading of the vehicle. The area is divided notionally into a number of equal sub-areas of predetermined dimensions, each having at least two differently-coded reflectors. The vehicle is first moved to a position from which it can scan initialization reflectors located at selected initialization positions.

Abstract: A vehicle guidance system includes a computer for generating signals to control a number of vehicles to carry out movements within a predetermined area. Data identifying locations of notional points on the floor of the area are entered into the computer together with a look-up table specifying pairs of those points between which movements of vehicles may be required, and specifying which other of the movements between pairs of points must be considered as potential causes of collision between vehicles when any particular movement is to be effected. When a vehicle movement is requested, the computer determines from the table which other movements must be considered, and determines whether any such movements are being effected at that instant. If so, the computer inhibits the requested vehicle movement or, if not, it initiates the requested vehicle movement.

Abstract: An electrical connector system includes self-terminating pin and socket terminals which have forward mating ends and identical rearward wire receiving ends. The wire receiving ends are mountable in a modular rear housing. The modular rear housing is mateable with either a front plug housing or a front receptacle housing. The terminals can be mass terminated by inserting a plurality of wires into the modular rear housing and by axially advancing the modular rear housing toward the front housing component of the system. The housing components can be readily separated from one another for repair or replacement of terminals. Selected connectors may be lockingly mountable to panels and may be lockingly mateable with one another.

Abstract: A dispensing cartridge comprising a plurality of stacked individual articles formed of rigid or semi-rigid thermoplastic material, each article being fusion bonded at its periphery to adjacent articles in the stacked relationship. The cartridges are formed by passing a stack of the articles through a heating zone to fusion bond the articles one to the other without producing any visual discontinuity about the periphery of the cartridge.

Abstract: An I.C. chip carrier and header assembly is provided. The assembly comprises a generally rectangular shrouded header with pins force fit therein. The pins are connectable to conductive traces on a printed circuit. A protective tape may be disposed over the header to control the locations at which conformal coatings may be applied, and thereby avoid extensive cleaning operations. The assembly further comprises a carrier with receptacles for receiving box-type double female carrier terminals. The I.C. chip is mountable in the carrier with the leads thereof being connectable to the carrier terminals by soldering. A cover is locked into engagement with the carrier to define a plugable subassembly. The subassembly is then urged into lockable but removable engagement with the header and the pins thereof.

Abstract: A vehicle control and guidance system in which a desired route for the vehicle is stored in the vehicle in the form of co-ordinates in a ground reference frame. The `vectors` between these junction points are divided by successive reference points into incremental vectors, the reference points being generated ahead of the vehicle at regular intervals. A dead reckoning system predicts the position of the vehicle at the end of each interval and this estimate is corrected, using a Kalman filter, by an independent fixed-target detection system using a scanning laser. The error between the estimated vehicle position and the local incremental vector provides a steering angle correction for the vehicle and the vehicle speed is dependent upon the lag of the vehicle behind the generation of reference points.
