Title: System and method for reading package information
Inventor: BJORNER JOHANNES A S
IPC: G06K9/00
Filed: 1996-09-20
Abstract: A system (10) for reading package information includes an imaging system (12) and a label decoding system (14). The imaging system (12) captures an image of a package surface (34) that includes a machine readable code such as a bar code (36) and an alphanumeric destination address (38). The label decoding system (14) locates and decodes the machine readable code and uses OCR techniques to read the destination address (38). The destination address is validated by comparing the decoded address to a database of valid addresses. If the decoded address is invalid, an image of the destination address is displayed on a workstation (30) and an operator enters the correct address. The system (10) forms a unified package record by combining the decoded bar code data and the correct destination address data. The unified package record is used for subsequently sorting and tracking the package (20) and is stored in a database and applied to a label that is affixed to the package (20).

Filed: 1996-11-06
Abstract: In a hard disk drive (20), heads (36) are cleaned by loading them onto a storage disk (10) and rotating the disk at a low speed which produces a high force of contact between the head and the disk to clean the head.  Periodically, a more thorough cleaning cycle is manually initiated. The heads are loaded onto a cleaning cartridge which has a disk surface which is mildly abrasive to the head. A low frequency is applied to the actuator arm (32) to vibrate the heads radially on the medium which is rotating at low speed.  Thereafter, the speed of the spindle (29) is increased up to the operating speed at which the heads are in pseudo contact with the disk surface. This cleaning cycle is repeated five times to clean the heads. The cleaning cycle is initiated by depressing the eject button (26) for longer than five seconds and placing the cleaning cartridge in the drive in response to a flashing LED  (27).

Inventor: CHEN JER-KANG
IPC: C12Q1/68
Filed: 1997-10-02
Abstract: The invention relates to methods and compositions for simultaneously generating a plurality of polynucleotide sequencing ladders or PCR  amplification products. Each sequencing ladder is generated from a recoverable primer, i.e., an oligonucleotide primer comprising a recovery tag. The recovery tag may be an oligonucleotide. Each sequencing ladder has a unique recovery tag. After the generation of the multiple sequencing ladders, the different sequencing ladders are separated from one another, i.e., purified, by binding to recovery tag binding compounds that have been immobilized on one or more solid supports. The recovery tag binding compounds are immobilized on the solid support in an addressable manner, i.e, the recovery tag binding compounds have distinct locations on the solid support. The binding of the sequencing ladders to the recovery tag binding compounds serves to separate the different polynucleotide sequencing ladders present in a given solution.  The separated sequencing ladders may then be released from the immobilized recovery tag binding compounds and subsequently resolved into individual components of the sequencing ladders or PCR products. The subject methods of separating sequencing ladders simultaneously generated in the same vessel may readily be adapted to separate a plurality of simultaneously generated polynucleotide amplification products. Other aspects of the invention are kits for the generation or recovery of a plurality of polynucleotide sequencing ladders or amplification products. The kits comprise a plurality of recoverable primers having unique recovery tags. Preferably, the recovery tags are polynucleotides that have substantially the same denaturation temperature when bound to appropriate recovery tag binding compounds, i.e., the primers comprise an integrated set. The kits may further comprise recovery tap binding compounds. The kits may further comprise labeled chain terminators. Other aspect of the invention include polynucleotide recovery devices.
