Abstract: Examples describe data security for communication systems. One example includes validating a merchant system using merchant data and generating a set of merchant credentials. The set of merchant credentials is then used in authentication to facilitate a secure transaction, which involves automatically generating transaction data with a tokenized client account number associated with the secure transaction. A refund request associated with the secure transaction is received with the set of merchant credentials that are used for automatically authenticating the merchant system. The example then involves accessing a database that includes the transaction data for automatically facilitating settlement of a refund payment using the authenticated merchant system and the transaction data.

Abstract: A sensor assembly may be mounted in a ceiling used with an associated light fixture. The sensor assembly may include a body including a sensor end and a blade end opposite the sensor end. A sensor may be disposed on the body nearer the sensor end than the blade end. A cutting blade may be disposed on the body nearer the blade end than the sensor end. The cutting blade may be configured to cut an opening in the ceiling. At least one retainer protrusion may be disposed on the body between the sensor and the cutting blade. The at least one retainer protrusion may be configured to retain the sensor assembly in the opening of the ceiling.

Abstract: Program execution profile data is collected by direct measurement of some code paths, and by inferring data for unmeasured paths. The data collection process may cause errors, which are propagated by the inferencing process. The profile data thus constructed is further enhanced by detecting certain data mismatches, and adjusting inferred data to reduce the scope of errors propagated during the inferencing process. Preferably, a control flow graph of the program being measured is constructed. Mismatches in the total weights of input arcs versus output arcs are detected. For certain specific types of mismatches, it can be known or guessed which count is incorrect, and this count is accordingly corrected. Correction of arc counts proceeds recursively until it is no longer possible to correct mismatches. Additionally, certain other conditions are adjusted as presumed inaccuracies.

Abstract: Disclosed are an apparatus, method, and program product which each provide an enhanced database engine. Access to precise values is provided while permitting unfettered access to those who are not interested in precise values. This is accomplished via an enhanced database index and indexing method. The entries of the database index are normalized to exclude precision. Individuals interested in precision can then specify precision as part of their query through use of a PRECISE keyword. Results are then filtered to account for the specified precision.

Abstract: A compiler (or interpreter) detects source language instructions performing arithmetic operations using a fixed point format (preferably packed decimal). Where the operation can be performed without loss of precision or violation of other constraints of the source language, the compiler automatically converts the operands to a floating point format (preferably Decimal Floating Point (DFP)) having hardware support, and re-converts results to the original fixed point format. Preferably, the compiler may combine multiple operations and instructions in an expression tree, analyze the tree, and selectively convert where possible. The compiler preferably performs a heuristic cost judgment in determining whether to use a particular conversion.

Abstract: A program feature set is compared to a processor feature set. The comparison may be performed in response to restoring the program onto a system or requesting its execution. The processor feature set represents zero, one or more optional hardware features supported by the processor, whereas the program feature set represents zero, one or more optional hardware features the program relies upon in its generated code. Comparison of the feature sets determines whether a particular program may run on a particular processor. Programs may be automatically or manually rebuilt to achieve full compatibility. If the comparison indicates that the program requires a feature not supported by the processor, the program is rebuilt based on the processor feature set. Alternatively, the program may be rebuilt in response to a rebuild request, rather than the comparison. The program is preferably rebuilt from an intermediate representation (IR) stored with or locatable from the program.

Abstract: A front-end compiler generates unique instructions for virtual method calls in intermediate representation code that may be passed to a back-end compiler. A back-end compiler in accordance with the preferred embodiments receives the intermediate representation code, and processes the unique instructions to generate therefrom equivalent code with explicit method calls, where possible. The machine code from the back-end compiler is then executed using sample inputs to generate profile data. The profile data and intermediate representation code are fed into the back-end compiler, which then generates code that may devirtualize virtual method calls according to the profile data by providing one or more explicit method calls for target methods that have an execution frequency (as indicated by the profile data) that exceeds a predetermined threshold.

Abstract: Systems, devices, and methods are provided to inhibit apparent amplitude modulation in non-linear processing that causes distortion in a processed signal. One aspect of the invention includes a hearing aid. The hearing aid includes a microphone to receive an input signal, a speaker to reproduce the input signal, and a processor. The processor processes the input signal using a gain. The processor includes an inhibitor, which inhibits distortions, and an adjuster, which adjusts the gain. The inhibitor acts to smooth an envelope of the input signal to inhibit undesired modulation. The adjuster adjusts the gain if the envelope is either above or below a threshold.

Abstract: Method, system and article of manufacture for monitoring variables. In one embodiment, information generated by a compiler is used to determine which variables need to be updated when performing a step, a “run to cursor” operation, and when a breakpoint is hit. This may be accomplished by providing as debugger data which variables may be affected at each statement of a program and a control flow graph for the program or procedure. The information about which variables may be affected can be stored as individual variables or sets of variables. When execution of the program being debugged is halted, only those variables whose values may have changed are refreshed in a variables window of a user interface.

Abstract: On implementation of the invention provides a stackable chip-scale package for improving memory density that may be mounted within a limited area or module. A novel staggered routing scheme enables the use of the same trace routing at every level of the stacked architecture for efficiently accessing individual memory devices in a chip-scale package stack. The use of a ball grid array chip-scale package architecture in combination with thermally compatible materials decreases the risk of thermal cracking while improving heat dissipation. Moreover, this architecture permits mounting support components, such as capacitors and resistors, on the chip-scale package.
