A method of detecting and attempting to correct a relay tack weld failure of its contacts is presented. This method senses the failure of a relay's contacts to open once it has been commanded to trip. This sensing may directly sense relay conditions, or may indirectly determine the failure by sensing a system parameter that shows the effects of the failure. Once the failure of the relay to open has been determined, the relay is again energized in an attempt to break loose the relay tack weld. If the relay fails to open after this first attempt, the relay may again be repulsed. Preferably a relay check timer is utilized to ensure that the system has stabilized before a repulse is attempted. A relay pulse timer may be used to control the pulse duration during these attempts. The number of attempts may also be limited.

Gaskets are provided for use in gas exchange measurement systems used for photosynthesis, respiration and transpiration measurements. Novel gaskets and gasket designs are provided, including composite gasket designs, along with corresponding construction techniques, which effectively provide low diffusion through bulk material, significant reductions in interfacial diffusion, sufficient compliance to conform to surface irregularities under low applied stresses, and/or low sorption properties, particularly of H2O vapor.

Systems and methods for selecting a form for crediting a payee by a payment service provider include receiving a request to pay a payee on behalf of a payer. A form for crediting the payee is selected based on at least one of a comparison of a payer account number associated with the payer and the payee to a merchant account scheme associated with the payee or a comparison of a payment amount associated with the received request to a merchant credit limit associated with the payee. A payment is directed to the payee in accordance with the selected form for crediting.

A safety system for a door-to-door jamb interface is provided. The safety interface uses several slidably joined members which are coupled to the door and its associated door jamb to prevent interaction between a user and the door-to-door jamb interface.

A gas flux chamber assembly is provided that includes a lift-and-rotate mechanism and a chamber. The chamber is moved between first and second positions, wherein the chamber is positioned over a sample in the first position and is positioned outside of an area above the sample in the second position. In operation, the chamber is first lifted off of the collar and is then rotated, about a rotational axis outside of the area above the collar. These acts are reversed to move the chamber from the second position to the first position.

To electronically present and pay bills, bill information representing a plurality of bills of a plurality of billers for a plurality of payors is transmitted to the plurality of payors. The transmitted bill information includes first information representing a first of the plurality of bills of a first of the plurality of billers for a first of the plurality of payors. A payment instruction from the first payor to pay the first bill, based on the transmitted first information, is received. A risk associated with payment of the first bill is determined and a debit type is selected based upon the determined risk. A payment of the first bill to the first biller is initiated based on the received payment instruction and to the selected debit type.

A storage controller and associated disk or disk portion where after the controller terminates its access to said disk or disk portion, data integrity problems in the disk or disk portion can be detected. Before host data associated with a write command is written from the cache memory to the disk or disk portion, an identity of the storage controller as a current user of the disk or disk portion and indication that the controller is operating in a mode it stores data in a cache is recorded on the disk or disk portion. If the storage controller is shut down abnormally, the record of the identity of the controller and the indication are not cleared. The storage controller is restarted or rebooted and the record is read to learn that the controller was using the disk or disk portion and operating in the foregoing mode before the shutdown.
摘要:
A method for generating a numeric or alpha-numeric identifier representative of a chemical structure having at least two atoms connected by a bond includes the step of assigning a numerical value to each atom and a numerical bond value to each bond. The method updates the numerical values for each atom based on the current values assigned to each atom and the numerical bond value. After the numerical values for each atom have been updated the method calculates a numeric or alpha-numeric identifier for the chemical structure.
