Abstract: ABSTRACT     In a relational database management system, interactive error-handling means comprises means for calling an operation means and a fetch means.  The fetch means operates against a cursor to retrieve a record occurrence noninteractively for operation.  The operation means validates the selected operation and can set an error condition signal.  When the selected operation is valid, the operation is performed and the operation means provides a return signal to the calling means, which calls the fetch means to retrieve the next record occurrence.  When the selected operation is invalid, the fetch means responds to the error condition signal by operating interactively to display the previously retrieved signal with an error message.  The interactive user can correct the error so that noninteractive operation can continue.

Title: Arrangement for a portable data carrier having multiple application files
Inventor: ANDERL EWALD C
IPC: G06F21/62
Filed: 1987-04-29
Granted: 1991-08-20
Abstract: ARRANGEMENT FOR A PORTABLE DATA CARRIER            HAVING MULTIPLE APPLICATION FILES            Abstract A portable data carrier typically the size of a standard plastic credit card is usable in a variety of applications, from custom repertory dialing to storage of individual medical and/or banking records. The portable data carrier provides a high security file system capable of supporting multiple applications, all independent of the details of the data carrier's generic internal structure. Although the data carrier looks and feels much like an ordinary credit card, it includes a computer and an electrically erasable programmable read-only memory. Power for operation of the portable data carrier is provided from an associated station via a reader/writer. The reader/writer also couples data between the data carrier and the associated station. Security is enhanced since application software in the station receiving and interpreting the data from a file sees a contiguous stream of bytes relating only to the file of the application being accessed. No information is provided to a user of a particular application about other applications in the data carrier or about the data carrier's internal file structure.

Title: Serial data bus for sci, spi and buffered spi modes of operation
Inventor: MIESTERFELD FREDERICK O R
IPC: H04L12/413
Filed: 1987-05-21
Granted: 1991-01-08
Abstract: ABSTRACT OF THE DISCLOSURE The aim of the Chrysler Collision Detector (CCD) Bus System is to allow multiple microprocessors to easily communicate with each other over a common pair of wires (called a bus) using a scheme similar to a telephone party line. All microprocessors connected to the bus are able to receive all messages transmitted on the bus. Any microprocessor with a message to transmit on the bus waits untilany current user is finished before attempting to use it. Whenever the bus is available, its use is allocated on a first-come, first-serve basis (i.e., whichever microprocessor first begins transmitting its message on the bus after any previous message finishes gets the use of the bus). If, however, multiple microprocessorsattempt to begin transmitting their messages on the bus at exactly the same time, then the message with the highest priority wins the use of the bus. All messageshave unique message priority values and each message is transmitted by only one microprocessor. The subject invention provides the ability to communicate with aSCI port, a SPI port or a buffered SPI port. This allows communication with any device configured with any one of these ports, all on the same bus.

Title: Line feed mechanism for line trimmers
Inventor: COLLINS IMACK L
IPC: A01D34/73
Filed: 1987-12-16
Granted: 1992-04-21
Abstract: ABSTRACT         The  cutting  head  assembly  of  a  motor-driven flexible  line  trimmer  has  a  line  feed  mechanism  which includes a housing member connected to and driven by a drive shaft from the prime mover and having a centrally located cylindrical wall  for  receiving  a compression spring.   A locking plate and cup member is reciprocably disposed around the cylindrical wall and compresses the spring substantially to its normal running position where it is held in position relative  to  the  housing  member  by  suitable  retention structure.   A spool is disposed around the cup portion of the locking plate and cup member and unless restrained, is free to rotate relative to the housing member to pay out line through an aperture in the housing member.   A cover ring member has a central opening which is coupled to the housing member and holds a ground engaging button member against the lower end of the cup member when both are in the lower,  normal  running  position,  yet  permits  the  button member to reciprocate upwardly against the locking plate and cup member to compress the spring when the button member is bumped against the ground.  The locking plate and cup member is driven by the housing member while being permitted to reciprocate axially, while the button member is driven by the cover ring member by way of the housing member while also permitting the button member to reciprocate axially. The spool is held against axial reciprocation by the cover member  and  the  housing  member  in  a  manner  permitting rotation of the spool relative to the housing.   The upper and lower faces of the spool have radially extending ribs which cooperate with locking teeth on the lower face of the locking plate and escapement teeth on the upper edge of the button member to lock the spool against rotation when the locking  plate  and  cup member  are  in  the  lower, normal running position, and to permit the spool to rotate through a controlled increment when the button is bumped against the ground and thus reciprocated, along with the locking plate member, upwardly then downwardly as a result of the biasing force of the spring.
