摘要:
A system and method of determining unprocessed items which is used to verify an item count based upon the number of radio frequency identification labels that have responded with their label information. The system includes an imaging system for producing image information about items in a container, and a computer for receiving label information from a radio frequency identification label reader following interrogation of a number of radio frequency identification labels on the items in the container, for producing a first count of the items from label information obtained from the number of radio frequency identification labels, for producing a second count of the items in the container from the image information, and for comparing the first count to the second count to produce a third count of the items not processed by the radio frequency identification label reader.

A retail terminal/customer service workstation integrates various retail devices and consolidates all of the associated functions of the retail devices and non-associated functions into a single, easy to use workstation. In accordance with one embodiment, the customer service workstation includes a large, touch-screen display, various customer payment devices, and other peripherals in electronic communication with and under the control of a microprocessing unit. A plurality of windows or areas is shown on the display according to the mode of the customer service workstation and/or transaction currently being processed by the customer service workstation. The customer service workstation is intelligently couplable with existing retail systems in order to supplement the existing retail system and obtain and use information/data therefrom, as well as provide various payment options.
摘要:
Sequence control apparatus provides a plurality of output signals selectively based upon either the rising or falling edge of a clock signal. The apparatus includes a plurality of groups of bistable devices such as flip flops. In each group, half of the flip flops are triggered by the rising edge of a clock pulse and the other half of the flip flops are triggered by the falling edge. The outputs of these flip flops are coupled to a series of gates, which in turn are controlled by logic input select signals to provide output signals which may be used, for example, for memory control purposes. The output signal from one group of flip flops is provided as an input signal for the next group.

A method for detecting the size of a DRAM memory includes the steps of establishing a table of memory bank configurations each having a different memory capacity, selecting one of the memory configuration, writing and reading a data word at the lowest address in the bank having the highest memory capacity, writing a data word at an address higher than the lowest address, reading the data word at the lowest address and storing the selected memory configuration in a storage register as the memory configuration of the memory when the data word read at the lowest address was not the word written at the highest address.
摘要:
A process for the production of 4-acetoxybutyraldehyde is described. The process comprises reacting allyl acetate with a mixture of carbon monoxide and hydrogen in the presence of a solvent and a catalyst comprising a rhodium complex and a diphosphine. The diphoshine is a substituted or unsubstituted 2,2′-bis(dihydrocarbylphosphino)diphenyl ether. The process gives a high ratio of 4-acetoxybutyraldehyde:3-acetoxy-2-methylpropionaldehyde.

A process for the production of 4-hydroxybutyraldehyde is described. The process comprises reacting allyl alcohol with a mixture of carbon monoxide and hydrogen in the presence of a solvent and a catalyst comprising a rhodium complex and a diphosphine. The diphoshine is a trans-1,2 -bis(bis(3,4-di-n-alkylphenyl)phosphinomethyl)cyclobutane and/or a 2,3-O-isopropylidene-2,3-dihydroxy-1,4-bis[bis(3,4-di-n-alkylphenyl)phosphino]butane. The process gives high yield of 4-hydroxybutyraldehyde compared to 3-hydroxy-2-methylpropionaldehyde.
摘要:
A catalyst, useful for the hydroformylation of allyl alcohol, is described. The catalyst comprises a rhodium complex and a 6-bis(3,5-dialkylphenyl)phosphino-N-pivaloyl-2-aminopyridine or a 3-bis(3,5-dialkylphenyl)phosphino-2H-isoquinolin-1-one. The invention also includes a process for the production of 4-hydroxybutyraldehyde comprising reacting allyl alcohol with a mixture of carbon monoxide and hydrogen in the presence of a solvent and the catalyst. The process gives a high ratio of the linear product 4-hydroxybutyraldehyde to the branched co-product 3-hydroxy-2-methylpropionaldehyde.
摘要:
A digital receipt (e-receipt) having various transaction data that is generated after a consumer transaction by a retail terminal or via a public or private electronic network may be forwarded to the consumer or third party with selective transaction data omitted from the digital receipt. The digital receipt is forwarded to the consumer either directly from the point of the transaction or indirectly via a data warehouse, clearing center or the like.
