Abstract: When the intake input mode is set and a 2D function key, such as “?{square root over ( )}” or “a/b,” is operated in a state where the cursor has been moved to an arbitrary position on the formula displayed on the display unit of an electronic calculator, the range of the formula covered by the input 2D function (or to be calculated) is determined on the basis of the position of the cursor by recognizing a formula part sandwiched by parentheses or a chunk of the formula part of a function with parentheses, recognizing a chunk of a formula part of a 2D function, recognizing a chunk of a formula part with successive numerals and characters, and recognizing the position of an arithmetic symbol (“+,” “?,” “×,” or “÷”) or a delimiter (“:” or “,”). The determined range is taken in by the input 2D function.

Abstract: A complex solver that is able to solve a diverse variety of model analytics. Upon identifying the various input variable(s) and output variable(s) of the model variables, if a straight forward solve is not to be performed, it is determined whether the model analytics is to be inverted such that a forward solve can be performed. For instance, it might not be known generally, or at least to the solver, how to invert a particular equation of other model analytics. If the model analytics is to be inverted, the model analytics is inverted, and the forward solve is performed. On the other hand, if the inversion of the model analytics is not to be performed, then a numerical analysis solve is performed.

Abstract: A cost-effective system that provides for the efficient protection of transmitted non-public attribute information may be used, for example, to control access to a secure area. Encryption of the attribute information may be performed using symmetric encryption techniques, such as XOR and/or stream cipher encryption. A centralized database that stores and transmits the encrypted attribute information may generate the encryption/decryption key based on selected information bytes, for example, as taken from a card inserted into a handheld device used at the secure area. The selected information to generate the encryption key stream may be varied on a periodic basis by the centralized database. Information as to which selected bytes are to be used for a particular access authorization request may be transmitted to the handheld unit or may be input through action of a user of the handheld unit, for example by entry of a PIN code.

Abstract: The invention relates to a system and a method for the securely recording input values used for processing in a safety-oriented processor.

Abstract: A method, system, and computer instructions for using MD4 checksum to link transactions across machines. Transaction information is received, wherein transaction information comprises a checksum and topology information, and wherein the checksum serves as a unique identifier of the current transaction. A first data structure is populated with the checksum and attribute information for the current transaction. A second data structure is then populated with the checksum and topology information for the current transaction, wherein populating the second table preserves a root/parent/current transaction relationship. Preserving the root/parent/current transaction relationship allows for automatically linking a transaction to its related transactions when the transaction is uploaded from a client to a transaction database.

Abstract: Disclosed are methods, systems, and computer program products for receiving input from a multi-function momentary switch by providing feedback from a user interface for each function associated with the switch. According to one method, alphanumeric input values are associated with a momentary switch. Each of the alphanumeric input values is associated with a different active time duration for the switch and at least two of the alphanumeric input values are associated with a same alphanumeric text entry mode. A duration of time the switch is in the active state is monitored. At least one of tactile and audible feedback is provided each time the duration of time matches a duration associated with an alphanumeric input value. The alphanumeric input value associated with the alphanumeric text entry mode and duration for the last feedback provided is selected as input from the switch.

The input device includes a set of number entry keys for data entry, enabling inputted data to be stored in registers in the memory, so that the user can fetch a specific datum from the registers sequentially with a function key for further editing through the number entry keys. When entering EDIT mode under statistic mode, the user can clearly find out the desired data for editing, and then delete or edit the data. By means of this humanized design, the user can conveniently review the correctness of every inputted data.

Abstract: A new method for identifying a predetermined number of data points of interest in a large data set. The data points of interest are ranked in relation to the distance to their neighboring points. The method employs partition-based detection algorithms to partition the data points and then compute upper and lower bounds for each partition. These bounds are then used to eliminate those partitions that do contain the predetermined number of data points of interest. The data points of interest are then computed from the remaining partitions that were not eliminated. The present method eliminates a significant number of data points from consideration as the points of interest, thereby resulting in substantial savings in computational expense compared to conventional methods employed to identify such points.

Abstract: The inventive computer includes a RAM which sequentially stores a series of calculation expression data thereto, a proof unit which proves the series of calculation expression data by inputting those data again, and a display which displays calculation data found to be non-coincident in the proof operation. First, when a series of calculation expression data is input to the computer, the computer performs a required calculation on the series of calculation expression data and sequentially stores the data in the RAM. After the series of calculations on the data is completed, the user inputs data on designation of a proof operation to confirm whether the result of the calculation is correct. Thus, the proof mode is selected and a second series of calculation expression data is input.
