Abstract: Systems and methods for enhancing the security of an electronic device by causing the electronic device to go into a mode for lost or stolen devices after a security component receives information regarding an event at the electronic device and determines that the event indicates the electronic device is lost or stolen.

Abstract: A software component, upon receiving a request for access to a provider having a plurality of service levels, determines the current security state of the requesting device. The security state of the requesting device varies according to severity levels of device security events. The software component compares that security state to a policy associated with the provider. The software component then allows the requesting device access to the provider services where the device's current security state meets or exceeds the security state required for the service.

Abstract: Methods and systems are provided for conditionally granting access to service levels based on a determined security state of the device requesting access. A software component, upon receiving a request for access to a provider having a plurality of service levels, determines the current security state of the requesting device. The software component compares that security state to a policy associated with the provider. The software component then allows the requesting device access to the provider services where the device's current security state meets or exceeds the security state required for the service.

Abstract: A method is provided for comparing a usage of a mobile communications device to a stored pattern of usage. When a measure associated with a difference between the usage and the stored usage pattern exceeds a threshold, the mobile communications device is caused to emit a sound encoded with information that may be decoded by another electronic device.

Abstract: Methods and systems are provided for sharing information and improving the functioning of devices by blocking potentially harmful communications. In the methods and systems disclosed, a security component on an electronic device may receive a policy. The security component may also receive, from a local device proxy on the electronic device, information pertaining to a communication. The security component may compare the information pertaining to the communication to the policy. The comparison may result in a determination that the communication is potentially harmful. The security component may then instruct the local device proxy to block the communication from proceeding past the local device proxy.

Abstract: A method, device, and system for evaluating a vessel of a patient, and in particular the hemodynamic impact of a stenosis within the vessel of a patient. Proximal and distal pressure measurements are made using first and second instrument while the first instrument is moved longitudinally through the vessel from a first position to a second position and the second instrument remains in a fixed longitudinal position within the vessel. A series of pressure ratio values are calculated, and a pressure ratio curve is generated. One or more stepped change in the pressure ratio curve are then identified and/or located using an Automatic Step Detection (ASD) process and/or algorithm.

Abstract: Apparatus and associated methods relate to transmitting an independent data stream from a beamforming base station to a User Equipment receiver in a beam directed based on the User Equipment transmitter signal Angle of Arrival estimated as a function of separately demodulated and jointly decoded User Equipment transmitter signals received by at least two spatially separated base station antennas, and scheduling transmission to and from the User Equipment as a function of the Angle of Arrival. In an illustrative example, the beamforming base station may be an LTE base station. The User Equipment may be, for example, a user's smartphone accessing the Internet. The independent data stream may be transmitted to the smartphone in a beam directed to the location of the smartphone. Various examples may advantageously provide higher bandwidth, for example a concentrated beam directed to User Equipment may provide an independent data stream with the full radio bandwidth.

Abstract: Disclosed herein is a composition for coating an optical fiber comprising a free radically curable acrylate and/or a methacrylate functionalized oligomer having a density of less than 1.0 g/cm3; where the acrylate and/or the methacrylate functionalized oligomer has a functionality of 1 or more; a photoinitiator, and optionally a free radically curable acrylate and/or methacrylate diluent monomer that has a density of less than 1.0 g/cm3; where the coating composition is disposed and cured on an optical fiber, where the density of the cured coating is less than 1.0 g/cm3; and where the average functionality of the composition is greater than one.

Abstract: A method is provided for comparing a usage of a mobile communications device to a stored pattern of usage. When a measure associated with a difference between the usage and the stored usage pattern exceeds a threshold, the mobile communications device is caused to emit a sound encoded with information that may be decoded by another electronic device.

Abstract: Methods and systems are provided for sharing information and improving the functioning of devices by blocking the installation of an application based on an assessment. In the methods and systems disclosed, a server may receive data pertaining to an application from the mobile communications device. The server may process the data from the mobile communications device to determine an assessment of the application, where the assessment is based on an analysis using information shared by sources other than the mobile communications device. The server may then provide the assessment to the mobile communications device.

Abstract: A method is provided for evaluating the usage of a mobile communications device that itself provides access to a resource. In the method, a detected usage of the mobile communications device is compared to a stored usage pattern of an authorized user. When a measure associated with the difference between the detected usage and the stored usage pattern exceeds a threshold, it is concluded that the mobile communications device is being used by an unauthorized user. In response to this conclusion, a restriction is placed on an ability of the mobile communications device to access the resource.

Abstract: A server receives from a mobile communication device information about a data object (e.g., application) on the device when the device cannot assess the data object. The server uses the information along with other information stored at the server to assess the data object. Based on the assessment, the device may be permitted to access the data object or the device may not be permitted to access the data object. The other information stored at the server can include data objects known to be bad, data objects known to be good, or both.

Abstract: Methods and systems are provided for sharing security risk information between collections of computing devices, such as mobile communications devices, to improve the functioning of devices associated with the collections. The methods and systems disclosed may share security risk information by identifying a security risk response by a first collection and then providing the security risk response to a second collection when a relationship database profile for the first collection indicates the security response may be shared with the second collection. Methods and systems are also provided for determining whether to allow a request from an originating device where the request may have been initiated by a remote device.
