Title: Account transaction system
Inventor: MYATT LARRY H
IPC: G07F7/08
Filed: 1991-06-11
Granted: 1996-01-09
Abstract: A system for performing transaction from an account such as a checking account which adds a measure of assurance of payment to the account issuer is provided.  The system includes a remote transaction terminal located at the point of the transaction.  The terminal reads data on a card which identifies the card holder.  The amount and type of the transaction are inputted into the transaction terminal.  A transaction processor is provided which accesses two negative data files. One of the negative data files is compiled by the account issuer and the other of the negative data files is compiled by a number of account issuers such as by a number of different merchants.  The data identifying the card holder is compared to the data in both of the negative files and an authorization or denial signal is generated in response to the comparison.

Granted: 2000-06-27
Abstract: A yeast cell, preferably Saccharomyces cerevisiae, which contains a functional stable recombinant DNA sequence that does not allow for the encoding of a negative regulator of phospholipid biosynthesis therein and which has multiple copies of an INO1 gene. In a preferred embodiment, the recombinant DNA sequence is an OPI1 gene deletion which results in the deregulation of inositol or inositol-containing metabolites such as inositol-1-phosphate synthase. Moreover, there is a method for obtaining inositol, inositol-containing metabolites or phospholipids such as myo-inositol or inositol-1-phosphate. The method comprises the steps of genetically engineering a stable yeast cell, preferably Saccharomyces cerevisiae, to continually produce inositol, inositol-containing metabolites or phospholipids. Additionally, them is the step of then generating the inositol, inositol-containing metabolites or phospholipids. In a preferred embodiment, the genetically engineering step includes the step of altering the negative regulatory step involved in phospholipid biosynthesis to overproduce inositol, inositol-containing metabolites or phospholipids such as myo-inositol.

Title: Automatic frequency control circuit
Inventor: KUMAGAI YOSHIAKI
IPC: H03J7/04
Filed: 1992-06-17
Granted: 2000-08-08
Abstract: An automatic frequency control (AFC) circuit receives input signals and generates converted signals by mixing the input signals with a local oscillation signal. An extraction circuit extracts a pilot signal, if present, from the input signals and provides the pilot signal to a switch. A frequency divider divides a frequency of the local oscillation signal output from a voltage controlled oscillator, and provides the frequency-divided local oscillation signal to the switch. The output of the switch is compared with a reference frequency in a phase comparator which generates a comparison result which controls the voltage controlled oscillator. If the pilot signal is not present, the switch selects the frequency-divided oscillation signal, to construct a phase-locked loop to stabilize the frequency of the local oscillation signal. Alternatively, an AFC circuit includes a frequency divider for selectively dividing a frequency of a pilot signal included in the converted signal.      Various frequencies of the pilot signal can be received by altering a division number in the frequency divider.

Granted: 2000-07-25
Abstract: A method is disclosed for protecting a harvested crop from pathogens comprising applying to the harvested crop and to any pathogen present thereon a compound capable of generating an active oligomer elicitor in the crop or the pathogen. The compound is applied with a penetrating agent which aids in the entry of the compound into the cuticle layer of the harvested crop or the pathogen. The elicitor is generated in the crop or the pathogen in an amount effective to elicit production in the crop of an anti-pathogenic agent. When the elicitor is generated in a pathogen present on the harvested crop, the elicitor is generated in sufficient amount to transfer into the crop, which transfer may be aided by the presence of said penetrating agent, in order to produce the desired phytoalexins in the harvested crop. Also disclosed is a composition comprising the above compound and a penetrating agent for the compound as well as a harvested crop treated with the above composition.

Abstract: The invention provides for protecting floating blocks of  text  or  other  portions  of  a  shared  data  object  in collaborative  computer  based  system  from  simultaneous manipulation  originating  with  two  or  more  users.  The collaborative  computer  based  system  includes  a  network connecting a plurality of terminals for communication.  Each terminal includes an output display device and a user input device.   A shared data object simultaneously accessible by a plurality of users of the  system.   Responsive to a user obtaining access to the  shared data object,  the user is assigned  a  cursor  available  for  display  on  the  visual display  devices  of  all  current  users.   Responsive  to movement by a user of his or her cursor, an attempt is made to establish a lock region  in the shared data  object  by determining   position   coordinates.    If   the   position coordinates do not include any portion of any previously established lock region, a lock region associated with the user's  cursor may be  established.   Movement of  a cursor operates to release any prior lock region associated with the cursor if a new lock is established or if the cursor leaves the old lock.

Patent CA-2100233-C (CA)

IPC: G01N27/62
Filed: 1993-07-09
Granted: 1999-02-02
Abstract: A sensor for determining the stoichiometric air to fuel ratio (A/F) at the input to the cylinders of an internal combustion engine which is based on measuring the change in the workfunction of a material which occurs when the oxidizing and reducing species in the adjacent gas phase are at or near their stoichiometric ratio.  In one method the sensor includes a material which is capable of thermionically emitting alkali metal or other appropriate ions into an exhaust gas atmosphere where they are subsequently collected by a nearby collector electrode and the magnitude of the emission current is measured The interaction of the emitting surface with the gas phase reversibly changes the workfunction of the emitting surface from large to smaller values as that gas phase is varied through the stoichiometric ratio with respect to the amounts of the oxidizing and reducing species in the gas.  Such a change in workfunction of the surface is accompanied by a change in the rate of the thermionic emission at the stoichiometric ratio thereby sensing that ratio in the gas phase which is proportional to the A/F at the input to the cylinders.

IPC: H04W52/04
Filed: 1993-11-26
Granted: 1997-06-10
Abstract: A high-frequency-signal detecting circuit is capable of smoothing a mean power in each time slot, and of performing rapid response during a transition time. A detector detects the envelope of a radio-frequency signal whose power level may change depending on the time slot.  A filter narrows the pass band in the data field of each time slot, and broadens it in the transition field of the same.  The output of the detector is applied to the filter.   The detecting circuit,  therefore, produces an output which is smoothed in the data field without regard to the content of data, and which sharply responds to a change in the power level in the transition field.
