Abstract: A clock signal in a clock distribution network is transmitted using network packets with the clock signal embedded within a bit of the network packets. The clock signal is adjusted to account for propagation delay in transmitting the clock signal throughout a clock distribution network. The propagation delay is computed using a round-trip packet. When a previous clock signal is received, a timer is set to a local clock's estimate of when the next clock signal will occur minus the propagation delay to the downstream device. When this timer expires, the clock signal is sent to the downstream device, which will allow it to arrive at the downstream device at the same time as the next clock signal is received on the local device.

Abstract: Pixelated-LED chips include substrate sidewalls with sidewall involutions and/or increased sidewall surface area regions to affect light extraction therefrom. A LED lighting device incorporates a superstrate that supports lumiphoric material and includes sidewalls with sidewall involutions and/or increased sidewall surface area regions. Methods for fabricating sidewall features may include etching (e.g., deep etching) of substrate or superstrate materials, such as by using an etch mask having edges with non-linear shapes to produce and/or enhance sidewall involutions when an etchant is supplied through the etch mask to selectively consume substrate or superstrate material.

Abstract: Protecting sensitive data from unauthorized disclosure is provided. For example, systems, methods, and computer readable storage devices are described that may be operable or configured to tokenize sensitive data attributes that may be included in a data file received from a client. Tokens that are anonymized but representative of the attributes may be generated and mapped to the sensitive data attributes. A tokenized data file may be de-tokenized and re-tokenized to perform processes that require the sensitive data attributes. A document may be transformed to protect the sensitive data attributes while reducing risk of disclosure of the sensitive data.

Abstract: A clock selection circuit allows seamless switching between different clock signals in a clock distribution network. The clock selection circuit can be an Integrated Circuit (IC). The clock signals can be analyzed by a processor in communication with the IC to ensure the clock signals are validated. Analysis can include comparing time stamps between received pulses of the clock signals to determine if the clock signals are occurring at regular intervals. The processor can then assign a priority order to the clock signals and select one of the clock signals to use. An identifier associated with the selected clock signal can be programmed into the IC. The IC can then redistribute the selected clock signal to multiple other ICs in a hierarchical clock distribution network. Ultimately, the distributed clock signal can be received by server computers to ensure instances being executed have accurate and synchronized timing.
