Hybrid fiber coaxial node
Digital information can be carried on the fiber leg of an access network using binary modulation. Binary modulated data received at an O/E node can then be modulated onto an analog waveform using quadrature amplitude modulation or some other technique for modulating an analog waveform and transmitted over, for example, the coaxial leg of the network.

Time-resolving sensor using shared PPD + SPAD pixel and spatial-temporal correlation for range measurement
A Time-of-Flight (TOF) technique is combined with analog amplitude modulation within each pixel in a pixel array using multiple Single Photon Avalanche Diodes (SPADs) in conjunction with a single Pinned Photo Diode (PPD) in each pixel. A SPAD may be shared among multiple neighboring pixels. The TOF information is added to the received light signal by the analog domain-based single-ended to differential converter inside the pixel itself. The spatial-temporal correlation among outputs of multiple, adjacent SPADs in a pixel is used to control the operation of the PPD to facilitate recording of TOF values and range of an object. Erroneous range measurements due to ambient light are prevented by stopping the charge transfer from the PPD—and, hence, recording a TOF value—only when two or more SPADs in the pixel are triggered within a pre-defined time interval. An autonomous navigation system with multi-SPAD pixels provides improved vision for drivers under difficult driving conditions. |

Privileged access to target services
A method of providing a client with a privileged access ticket (PAT) to access a target service is performed at a credentials management service (CMS) in communication with a client and an authentication service. The CMS receives a privileged access ticket request from the client. The PAT request uses authentication credentials. The CMS retrieves privileged credentials using the authentication credentials, and sends a PAT request to the authentication service using the privileged credentials.
