Abstract: A light source unit generates an optical signal out of a bend-insensitive (“BI”) optical fiber that is compliant with a desired encircled flux (“EF”). The unit includes a light source to generate an optical light signal and a conventional multimode optical fiber coupled to receive the optical light signal from the light source at a first end. A modal conditioner is arranged to condition the optical light signal propagating along different modes of the conventional multimode fiber. A first bend-insensitive (BI) multimode optical fiber has an input end, the input end of the first BI multimode optical fiber being coupled at a second end of the conventional multimode optical fiber to receive the conditioned optical light signal from the conventional multimode fiber. The output from the first BI multimode optical fiber outputs an optical signal having the desired EF.

Abstract: Described are techniques and systems for secure camera based IMU calibration for stationary systems, including vehicles. Existing vehicle camera systems are employed, with enhanced security to prevent malicious attempts by hackers to try and cause a vehicle to enter IMU calibration mode. IMU calibration occurs when a calibration system determines the vehicle is parked in a controlled environment; calibration targets are positioned at different viewing angles to vehicle cameras to act as sources of optical patterns of encoded data. Features of the patterns are for security as well as for alignment functionality. Images of the calibration targets enable inference of a vehicle coordinate system, from which calculations for IMU mounting error compensations are performed. A relative rotation between the IMU and the vehicle coordinate system are applied to IMU data to compensate for relative rotations between the vehicle and the IMU, thereby improving vehicle slope and bank metrics.

Abstract: Methods and apparatus are described by which a rich, time-correlated information set is captured during automated testing of an application in a way that allows the application developer to understand the state of the application under test (AUT), the browser interacting with the AUT, and/or the device interacting with the AUT, as it/they changed over time. Mechanisms or features associated with browsers and/or device operating systems are exploited to capture such information, not only for the purpose of better understanding individual test runs, but also to enable the use of analytics over data sets.

Abstract: An authentication system includes an authentication module maintaining a store of credentials for a set of users. In response to an identity specified by credentials provided from a requestor address not being found in the store of credentials, the authentication module transmits an authentication failure response. In response to the provided credentials matching selected credentials, the authentication module transmits an authentication success response. The authentication system includes an analyzer module configured to determine a number of identity-not-found failures corresponding to a first address, identify a triggering event in response to the number exceeding a predetermined threshold, and, in response to the triggering event, add the first address to a block list.

When the first and second assemblies are in the second position, each rail of the second assembly is at least partially nested in one of a pair of channels formed in the top cap.

Abstract: Methods, computer systems, and computer storage media are provided for sorting and presenting a patient's medical information by body system. A selection of a body system filter directed to a body system is received, and the patient's medical information is accessed. The selected body system filter is applied to the patient's medical information to generate a set of body-system specific patient information. The body-system specific patient information is presented on a body system view user interface.

Abstract: Systems, methods and products for identifying IP mass hosts and determining whether they are good or bad. One embodiment is a method including selecting a first candidate IP address, identifying a set of domains hosted at the IP address, and identifying registrants of the domains. A number of unique ones of the registrants is determined and if the number of unique registrants exceeds a threshold number, the candidate IP address is deemed an IP mass host. Otherwise, the candidate IP address is deemed not to be an IP mass host. For an IP mass host, domains that have bad reputations are identified, and it is determined whether the bad domains comprise at least a threshold percentage of the total hosted domains. If the IP mass host has at least the threshold percentage of bad domains, the IP mass host is deemed a bad mass host.

Abstract: Systems, methods and products for determining the trustworthiness of anonymous sensors, including a sensor health check, a data ballpark check, a reputation comparison, and optional “last resort” procedures. The sensor health check examines sensor operating parameters to see if they fall within an envelope of expected values. If not, the sensor is unhealthy and is not trusted. The data ballpark check determines whether the sensor's traffic data falls within a predefined envelope of values. If the sensor is healthy and the traffic is within expected ranges, the sensor is trusted. If the traffic data is outside expected ranges, the reputation comparison, determines whether IP addresses, domains or other IOCs in the traffic data are found in the reputation list which may corroborate the traffic as trustworthy because it represents malicious or not-in-the-wild traffic. “Last resort” procedures may include applying safelists/blocklists, signature controls etc. to verify sensor/data trustworthiness.
