International Classification:

H04K 1/10

US Classification:

375260

Abstract:

A system for detection and avoidance of victim services in ultra-wideband (UWB) systems is provided. A detect and avoid module may calculate power averages of Orthogonal Frequency Division Multiplexing tones. The power of tones may be measured and compared with power averages of corresponding tones. If a measured tone power exceeds an average power of a corresponding tone by a dynamic threshold, the tone may be identified as associated with an interferer. The threshold may be inversely related to the gain level of an automatic gain control module. The UWB subsystem may be configured with known bands of victim services of other radio frequency systems, and a tone identified as associated with an interferer that is within a known victim service band may be identified as a victim service. The UWB subsystem may attenuate or otherwise suppress transmission within the victim service band to avoid interfering with the victim service.

International Classification:

G06F 9/26

US Classification:

712241

Abstract:

In an embodiment, a microcode unit for a processor is contemplated. The microcode unit comprises a microcode memory storing a plurality of microcode routines executable by the processor, wherein each microcode routine comprises two or more microcode operations. Coupled to the microcode memory, the sequence control unit is configured to control reading microcode operations from the microcode memory to be issued for execution by the processor. The sequence control unit is configured to stall issuance of microcode operations forming a body of a loop in a first routine of the plurality of microcode routines until a loop counter value that indicates a number of iterations of the loop is received by the sequence control unit.

Abstract:

A method, system, and computer-readable medium for detecting an interferer in a wireless communication system are provided. The method includes receiving a signal having P tones, each of the P tones being associated with a frequency, determining a first signal quality of each of the P tones, determining a second signal quality of each of the P tones, and detecting the interferer that occupies the same frequency as one of the P tones based on the respective first signal quality and the respective second signal quality. The first signal quality and second signal quality behave differently when the interferer is present. The detecting the interferer includes determining a discrepancy in the behavior of the first signal quality and the second signal quality.

International Classification:

G06F 17/30

US Classification:

707610, 707640

Abstract:

A file I/O operation is initiated to store a result of a file I/O operation in a destination file. In response to the file I/O operation being in progress, an amount of the file I/O operation currently completed is monitored. In response to determining that the amount of the file I/O operation currently completed is less than a threshold amount, another destination file is specified through a user interface, in which to store a result of file I/O operation not yet completed. The file I/O operation stores the remaining result of the file I/O operation at the another destination file. A single file handle is updated for the result of the file I/O operation to reference the destination file comprising the portion of the result and the another destination file comprising the remaining result.

US Classification:

235380

Abstract:

Conducting payment card transactions through a payment network through a card reader with a merchant authentication code attached. A payment is processed in connection with a transaction using a payment card. Prior to approving the transaction, the payment card holder is contacted and requested to provide the merchant authentication code. If the merchant authentication code provided by the payment card holder is consistent with the merchant authentication code affixed to the device, approving the transaction. The merchant authentication code may be text, a bar code, a quick response code, a hologram or other code. The merchant authentication code may include information regarding the merchant such as location, business name and the like.

US Classification:

235380

Abstract:

Conducting payment card transactions through a networked device of a user wherein the networked device comprises a card reader and a wireless application operated by the networked device. The transaction may comprise acquiring information from a client's payment card using the card reader; providing such information from the card reader to the networked device through a headphone or similar jack; and processing the data through the mobile application connected to a payment network. More specifically, the networked device transmits a known first signal to the card reader, the card reader returns a second signal which is a function of the first signal and a third signal generated by the card reader that is indicative of information stored on a payment card, and the networked device derives the third signal from the first signal and the function applied to the first signal and the third signal.
