  • Publication number: 20170366978
    Abstract: Various embodiments provide methods, devices, and non-transitory processor-readable storage media enabling network path probing with a communications device by sending probes via a network connection to a STUN server and receiving probe replies. The communications device may increment a counter and transmit a test probe configured to be dropped at the first access point (NAT) causing all subsequent NATs to release their IP/port mappings. The communications device may send another probe to the STUN server and receive a probe reply. The communications device may compare the first and second probe replies to determine whether the final IP addresses within the network path match. By continuously incrementing the counter and querying access points, the communications device may determine the number of access points lay along any given network path. The presence of addition or unexpected numbers of NAT Servers may indicate the presence of a rogue access point.

  • Publication number: 20170318426
    Abstract: Systems, apparatus and methods for selecting a base station or a set of base stations for RTT measurements, or other interactive radio localization technique, to determine a position fix of a device are presented. The method imposes a processing load on only inactive or less active base stations. Busy or busier base stations are not used in the interactive radio localization technique. By imposing a processing load on only less active base stations, transmitting devices may be under loaded and encounter a more uniform processing delay, and thus provide a more accurate measurement resulting in a more accurate position fix.

  • Publication number: 20170308701
    Abstract: A network and its devices may be protected from non-benign behavior, malware, and cyber attacks caused by downloading software by configuring a server computing device to work in conjunction with the devices in the network. The server computing device may be configured to receive a software application from an application download service, establish a secure communication link to a client computing device in the network, receive exercise information from the client computing device via the secure communication link, use the received exercise information to exercise the received software application in a client computing device emulator to identify one or more behaviors, and determine whether the identified behaviors are benign. The server computing device may send the software application to the client computing device in response to determining that the identified behaviors are benign, and quarantine the software application in response to determining that the identified behaviors are not benign.

  • Publication number: 20170284236
    Abstract: A switchable valve train assembly including a carrier housing defining a hydraulic circuit, a supply assembly, a plurality of rocker shafts, a plurality of separators, and a plurality of rocker arm assemblies is provided. Each one of the plurality of separators divides the rocker shafts into (1) a first chamber extending between a first chamber axial end and the separator, and (2) a second chamber extending between a second chamber axial end and the separator. The plurality of separators each include an orifice defined between the first chamber and the second chamber that provides fluid connection between the first chamber and the second chamber. Locking assemblies of the rocker arm assemblies are selectively actuated based on the supply assembly. The separators ensure that hydraulic fluid within the hydraulic fluid is de-aerated and that the second chambers remain primed with hydraulic fluid for faster actuation of the locking assemblies.

  • Publication number: 20170279701
    Abstract: Various embodiments provide methods, devices, and non-transitory processor-readable storage media enabling network probing with a communication device based on the communication device sending a probe via a first network connection and receiving the probe via a second network connection. By leveraging a capability of a communication device to establish two network connections at the same time, various embodiments may enable a single communication device to act as both a probing client and a probing server. In this manner, various embodiments may enable standalone network probing, i.e., network probing that may not require a remote dedicated probing server to act as a probe generator or a probe sink.

A server computing device receiving vehicle information from a reporting vehicle may compare the received vehicle information to contextual information to generate a comparison result, and determine whether the received vehicle information should be evaluated with greater scrutiny based on the comparison result. The server computing device may select sensors for polling based on the received vehicle information (and in response to determining that the received vehicle information should be evaluated with greater scrutiny), and poll the selected sensors to received sensor information. The server computing device may use the received sensor information to corroborate the received vehicle information, and perform a responsive action based on the result of the corroboration.

  • Patent number: 9743241
    Abstract: Systems, apparatus and methods for estimating a location of a mobile device are presented. Before computing a location estimate, the mobile device groups a plurality of access points into two or more categories (for example, a first list of access points having a first characteristic and a second list of access points having a second characteristic). Round-trip time (RTT) measurements are computed for access points in the first list. A Short Interframe Space (SIFS) value may be determined for each access point in the first list or generally SIFT representing the first list as a whole. The RTT measurements are compensated with the appropriate SIFS value. The mobile device then computes its location or position fix estimate using the compensated RTT values while excluding less accurate RTT values from other access points. As a result, the location estimate eliminates adverse influent from some access points.
