Abstract: A wireless device may alert a wireless smart card reader that communication of data between the wireless device and the wireless smart card reader is probably imminent by sending an activation alert. Upon receipt of the activation alert, if the wireless smart card reader is in a low-power state, the wireless smart card reader may enter a higher-power state. If the wireless smart card reader is in the higher-power state upon receipt of the activation alert, the wireless smart card reader may remain in the higher-power state until a timeout period has expired. The wireless device may instruct the wireless smart card reader to enter the low-power state by sending a deactivation alert if the wireless device detects that communication of data between the wireless device and the wireless smart card reader is not likely to occur within a specified period of time.

Abstract: In accordance with a representative embodiment, a method for reducing the effect of jitter in a sampled signal is described. The method comprises: obtaining a frequency-domain data set representing the sampled signal; obtaining an average sideband amplitude distribution generated by jitter around one or more principal frequencies of the signal; estimating the jitter phases for sidebands generated by jitter in the frequency-domain data set; subtracting a jitter contribution characterized by the average sideband amplitude distribution and the estimated jitter phases from the data record.

Abstract: Communications between a computing device and a smart card reader (SCR) configured for communication with a smart card are facilitated through the use, by the computing device, of a smart card resource manager and a smart card reader service (SCRS). The SCRS acts as a relay for commands between the smart card resource manager and the SCR. Appropriate configuration of the SCRS obviates a redundant downloading of certificates from smart card to computing device subsequent to loss of a connection between the computing device and the SCR. However, upon re-establishing a previously lost connection to a SCR and determining that a communication link between a smart card and the SCR has been ended and reestablished during the loss of connection, the SCRS may indicate to the smart card resource manager that smart card is absent and, subsequently, that the smart card is present.

Abstract translation: 通过计算设备使用智能卡资源管理器和智能卡阅读器服务（SCRS），便于通过配置用于与智能卡通信的计算设备和智能卡阅读器（SCR）之间的通信。 SCRS充当智能卡资源管理器和SCR之间的命令的中继。 在计算设备和SCR之间的连接丢失之后，SCRS的适当配置消除了证书从智能卡到计算设备的冗余下载。 然而，在重新建立与SCR的先前丢失的连接并且确定智能卡和SCR之间的通信链路已经在连接丢失期间已经结束并被重新建立时，SCRS可以向智能卡资源管理器指示智能卡 不存在，随后智能卡存在。

Abstract: A beamformer is arranged to receive an input from a first antenna element and from at least one other antenna element and to generate at least a first and second output beam. The first and second output beams are combined at a connecting port such that signals received at the first antenna element are constructively combined at the connecting port and signals received at another antenna element or elements are destructively combined at the connecting port, so that a receiver connected to the connecting port may receive signals from the first antenna element and may not receive signals from the other antenna element or elements. The arrangement may also be used to transmit a signal which is fed into the connecting point from the first antenna element and not from the other antenna element or elements.
