摘要:
One method of estimating timing and frequency information of a payload transmitted through two or more frequency separated channels combines training fields from preambles from the two or more frequency separated channels to construct combined values that may be used to estimate the frequency and timing information. In one embodiment, the combined values may be determined by combining self-correlated training fields from the frequency separated channels. Another method of estimating the timing and frequency information selects the training fields from the preamble of one of the frequency separated channels based upon a signal quality metric. In another embodiment, the selection of the training fields based upon a signal quality metric may be biased to favor a particular channel.

A software license for a particular version of a software product on a computing device includes both a branding identifier that identifies the particular version of the software product and component dependency information that identifies one or more aspects of the particular version of the software product. To activate a software product on the computing device, the branding identifier is compared to a portion of the software product on the computing device. If the branding identifier matches the portion of the software product, then the component dependency information is compared to one or more aspects of the software product on the computing device. If the component dependency information matches the one or more aspects of the software product then the software product is activated. Otherwise, the a license state of the software product is kept unchanged.

A notification routing system may include a data storage system and a notification routing module. The data storage system may store the identity of entities and, for each entity, the identity of a group of cellular communication devices used by the entity. The notification routing module may detect a notification that is directed to at least one of the cellular communication devices, determine which cellular communication device is active within the group of cellular communication devices to which the notification is directed, and route the notification to the active cellular communication device.

The invention is a crawling pad for the babies with a replaceable intelligence patch. The characteristic lies in: The crawling pad is divided into several areas based on different colorful design with allocated pockets by suture. The LED lamination and sound chips formed an intelligence patch can be inserted into individual pocket on the pad. The inserted intelligence patch comprises of: printed circuit board, LED lamination, sound chip and a controller with the automatic time-delay switch. All these components are set inside a fully heat-sealed patch that is formed: a printed decorative vinyl cover; then a soft lining on top of the electronic components; and the bottom is a clear/solid color vinyl. The bright patterns and sound enhance the cause and effect development to the babies at their early age. The variety choices of changeable patch with different patterns and sound empower the babies gaining new knowledge over time.

Systems, apparatus and methods for determining a cyclic shift diversity (CSD) mode are presented. Examples use two different autocorrelations to determine a current CSD mode. Specifically, a delay-based autocorrelation and a cyclic shift-based autocorrelation are each computed then compared to each other, for example, by taking a difference of the two autocorrelations. A multipath signal leads to similar autocorrelations, where as a signal with a CSD mode enabled leads to dissimilar autocorrelations. By examining the number of peaks in the delay-based autocorrelation or the autocorrelation difference, a current CSD mode may be determined.

The main bus-bar assembly includes a first main bus-bar and a second main bus-bar attached to the first main bus-bar. The assistant bus-bar assembly includes a first assistant bus-bar and a second assistant bus-bar attached to the first assistant bus-bar. The first assistant bus-bar is electronically connected to the first main bus-bar, and the second assistant bus-bar is connected to the second main bus-bar. Each of the plurality of connector includes a first pin and a second pin. The first pin is engaged with the first assistant bus-bar, and the second pin is engaged with the second assistant bus-bar.
摘要:
A mobile station is configured to authenticate applications running thereon in order to control access by the authenticated applications to secure data stored in a subscriber identity module of the mobile station. Sensitive data securely stored in the subscriber identity module is associated with one of multiple personas implemented on the mobile station. When an application running on the mobile station requests access to the secure data, a secure domain controller processes the request and authenticates the application, for example based on an application authentication key. The secure domain controller further determines whether the application is associated with the same persona as the secure data identified in the request. If the application is authenticated, the secure domain controller then allows the application to access secure data associated with the same persona, but prevents the application from accessing secure data associated with other personas.

摘要:
Functionality can be implemented for automatic gain control (AGC) in a wireless network device to determine whether to change the gain of the wireless network device based on determining the strength of an RF signal. At various time instants, the strength of the RF signal can be compared against different thresholds to determine the presence of and severity of the saturation of the RF front end. The gain settings can be adjusted based on comparing the strength of the RF signal with a set of thresholds. This can help the wireless network device receive RF signals with little or no distortion, and can minimize RF saturation, gain compression, false detection and other performance degradation at the wireless network device.

A receiver for a wireless communication device comprising a mechanism for performing spur mitigation. A spur mitigation unit of the receiver is operable to determine a current estimate of a spur signal from an ADC output signal using a growing box filter. The spur mitigation unit can determine a power of the current estimate of the spur signal and a power of a previous estimate of the spur signal using a power measurement unit. The spur mitigation unit can determine whether the power of the previous estimate of the spur signal is greater than the power of the current estimate of the spur signal. If the power of the previous spur signal estimate is greater than the power of the current spur signal estimate, the spur mitigation unit can remove the spur signal from the ADC output signal based on the previous spur signal estimate.
