    摘要: A system suitable for use in classifying radio signals includes a plurality of feature extractors configured to extract a plurality of features from an object and a plurality of classification layers. Each of the plurality of classification layers includes one or more reduced enhanced Gaussian classifiers selected from a plurality of Gaussian classifiers based on a classification error rate of each of the plurality of Gaussian classifiers and configured to classify the object as belonging to an object class in a subgroup of correctly classified object classes or in a disjoint error subgroup that needs further classification, using at least one of the extracted plurality of features. If the object is classified as belonging to an object class in a disjoint error subgroup at a layer, the object is passed on to a different reduced enhanced Gaussian classifier in a next layer for further classification.

    摘要: Examples of the disclosure enable a set top box to be installed. In some examples, a remote control device, a computing device, and a set top box are provided. The computing device downloads configuration information for a location and receives input from an installer at the location. The set top box includes a remote control interface that receives commands from the remote control device, a local communications channel that transmits data to the computing device, an emulator that emulates the receipt of the commands by injecting remote control keypresses into the remote control interface to issue the commands, and a diagnostic feature activatable over the local communications channel by the computing device after the computing device receives the input to perform verification tests and to return results of the verification tests to the computing device to confirm to the installer that the set top box has been installed correctly.

    摘要: A system includes one or more hardware processors causing performance of operations. The operations include transmitting, by a first access point, a set of one or more wireless signals that include a request for feedback information. The set of wireless signals incorrectly identifies a second access point as the sender of the set of wireless signals instead of correctly identifying the first access point as the sender of the set of wireless signals. The operations further include receiving, from a client device associated with the second access point, a feedback information corresponding to the receipt of the set of wireless signals by the client device, and, based on the feedback information: determining a distance between the first access point and the client device that is associated with the second access point.

    摘要: A remote management system employs multiple wireless links, which may include a local wireless link and a remote wireless link. The remote wireless link may be in place between a troubleshooting device held by a person located at a service site, and a remote service center for a service provider, such as an Internet service provider. The local wireless link may be in place between the person at the service site and the equipment needing service, such as a DSL model provided by the service provider. Establishing the multiple links allows the service provider to troubleshoot the equipment, without incurring the substantial cost of sending a specialized service technician to the service site. As examples, the troubleshooting device may be a smart phone, the remote wireless link may be a cellular connection, and the local wireless link may be a Bluetooth or NFC connection.
