    Abstract: Techniques are described for reducing frequency pulling in voltage-controlled oscillator (VCO) circuits. Some embodiments operate in context of a transmitter having a VCO and a power amplifier (PA), where resonant components of the VCO are impacted by magnetically coupled feedback from resonant components of the PA. The VCO and PA are coupled via a set of signal path components that cause signal path delay, such that the feedback signal is phase-delayed with respect to the signal generated by the VCO. A coupling delay matching system is used to introduce additional delay, thereby further phase-shifting the feedback signal to an integer multiple of the oscillation period of the VCO signal; thereby reducing frequency pulling of the VCO.

  • Patent number: 10505653
    Abstract: The present disclosure describes methods and apparatuses for fine timing measurement with frequency domain processing. In some aspects, a first device receives a frame that is transmitted by a second device via a wireless medium. A degree to which the frame is affected by multipath propagation in the wireless medium is determined based on frequency power and linear phase of the frame, which can be calculated using frequency domain processing. Based on the degree to which the frame is affected, a time of arrival calculation for the frame can be compensated for effects related to the multipath propagation. By so doing, the effects of multipath propagation can be addressed without time domain processing, which is typically complex and more expensive to implement.

  • Patent number: 10405287
    Abstract: A signal is emitted by an unrelated, non-cooperating party. The SA scans this spectrum, and selects and filters to a portion of the signal emitted. The SA, using its internal clock, time tags a sequence of peaks of the time domain of the filtered signal. The SA sends (over the internet or other method) the time tagged peaks, frequency and location of the emission to the IN. The IN receives the message from the SA. It compares the peaks with its own data, collected using its local antenna at the specified frequency. The IN uses its location, and the location encoded in the message, to compute the different time of arrival of the signal, and uses the locally found peaks at that frequency to determine a “phase shift.” The phase shift is used to calculate the local clock skew. The SA repeats step 2, selecting a different frequency.

  • Patent number: 10148411
    Abstract: The present disclosure provides a secure one-step IEEE 1588 clock using either a symmetric or asymmetric protection scheme. Clocks of mission-critical or highly-available devices in industrial automation systems connected to a communication network are synchronized by sending, by a master clock, a synchronization message, e.g., a single message of the one-step-clock type according to IEEE 1588, including a time stamp, and by receiving and evaluating, by a slave clock, the synchronization message. A synchronization component or module of the master clock prepares, or composes, prior to a projected send time, a synchronization message including a time stamp of the projected send time, and secures the synchronization message in advance of the projected send time. Securing the synchronization message occurs by suitable cryptographic means allowing for authentication of the time stamp at a receiving slave clock. At the projected send time, the secured synchronization message is transmitted.

It can communicate this information to a base station (210) of the second wireless communication network (200). The base station (210) of the second wireless communication network (200) can then use this information to more efficiently allocate frequency channels and/or time slots for future traffic reservations of the first station (220) of the second wireless communication network (200).

  • Patent number: 9736271
    Abstract: Described herein are improved systems, methods, and devices for delivering and managing metadata in a distributed computing platform such as a content delivery network (CDN) so as to configure content servers to handle client requests. The teachings hereof provide, among other things, scalable and configurable solutions for delivering and managing metadata, preferably by leveraging dynamically obtained control information. For example, in one embodiment, a given content server may store metadata, e.g., in a configuration file, that references dynamic, late-bound control information for use in satisfying dependencies. This dynamic control information can be requested by the CDN content server, typically from a remote host, when needed to parse and execute the metadata.

  • Patent number: 9697171
    Abstract: A method begins by a processing module of a computing device receiving a most current revision value for a data element, where a revision value for the data element is generated based on a current time of a storing device. The method continues with the processing module generating a new revision value for a currently revised version of the data element based on a current time of the computing device and comparing the current time of the new revision value with the current time of the most current revision value. When the current time of the new revision value precedes the current time of the most current revision value, the method continues with the processing module adjusting the new revision value to produce an adjusted revision value and facilitating storage of the currently revised version of the data element having the adjusted revision value.
