Abstract: One embodiment of a display backlight driver integrated circuit can be configured for operation in at least two different ways. A first method transfers data from an EEPROM to hardware registers prior to regular operation. A second method also transfers data from an EEPROM to registers. However, hardware registers can be overwritten with data accepted from a control bus, prior to regular operation. A keyboard driver IC can detect the presence or absence of a cable to an LED. If the cable is absent, the driver IC will not supply power for the LED. One embodiment of a keyboard and display backlight control system can be configured to allow substantially independent operation.

Abstract: A test code generation technique that replaces instructions having a machine state dependent result with special redirection instructions provides generation of test code in which state dependent execution choices are made without a state model. Redirection instructions cause execution of a handler than examines the machine state and replaces the redirection instruction with a replacement instruction having a desired result resolved in accordance with the current machine state. The instructions that are replaced may be conditional branch instructions and the result a desired execution path. The examination of the machine state permits determination of a branch condition for the replacement instruction so that the next pass of the test code executes along the desired path. Alternatively, the handler can execute a jump to the branch instruction, causing immediate execution of the desired branch path.

Abstract: Validation data, such as an image selected by a merchant, is rendered on a mobile device of a customer to provide the merchant confirmation that payment for an item submitted through the mobile device of the customer was in fact received by the merchant. The merchant may establish an account on a network-accessible computing device (e.g., in the “cloud”) that includes the validation data. The customer authorizes payment to the merchant from the mobile device using the network connectivity of the mobile device. When the payment is received by the merchant, the network-accessible computing device sends the validation data to the customer's mobile device. The merchant may be confident that he or she has in fact received an electronic payment from the customer when the validation data is presented on the mobile device. Techniques to prevent reuse and copying of the validation data are also discussed.

Abstract: A hypervisor receives an interrupt that includes a target address and, in turn, branches to an administrating interrupt vector. Next, the administrating interrupt vector determines whether to branch to a piggyback interrupt handler corresponding to a piggyback interrupt vector. Based upon the determination, the hypervisor either branches to the piggyback interrupt handler or to an administrating interrupt handler that corresponds to the administrating interrupt vector.

Abstract: A band that employs low voltage resistance wire (11) to provide heat for the purpose of relieving the pain and discomfort caused by menstrual cramps. It is wrapped around the hip/lower abdominal area of the body and velcro (1, 2) is used to hold it in place. In addition to the velcro, elastic materials (7) enable the abdominal heat band to have an adjustable size so that it is able to fit both large and small individuals. Elastic also helps provide a snug fit allowing the user to effectively conceal the band beneath their clothing if desired. A remote control (3), which also houses the battery, controls the power and intensity of the heat. The remote is detachable from the band which allows the band to be washed without risk of getting the remote control wet.

Abstract: A system for stealing interrupt vectors from an operating system. Custom interrupt handler extensions are copied into an allocated block of memory from a kernel module. Also, operating system interrupt handlers are copied into a reserved space in the allocated block of memory from an interrupt vector memory location. In response to copying the operating system interrupt handlers into the reserved space in the allocated block of memory, custom interrupt handlers from the kernel module are copied over the operating system interrupt handlers in the interrupt vector memory location. The custom interrupt handlers after being copied into the interrupt vector memory location handle all interrupts received by the operating system.

Abstract: Computer implemented method, system and computer usable program code for configuring a computing system. A determination is made whether there are any errors in the model, and responsive to determining that there is at least one error in the model, a determination is made whether there is at least one resolution for correcting the at least one error. Responsive to determining that there is at least one resolution for correcting the at least one error, at least one resolution among the at least one resolution for correcting the at least one error is selected to form at least one selected resolution to correct the at least one error. The at least one selected resolution is applied to the model to form a transformed model, and the transformed model is output to a user.
