Methods and apparatuses relate to detection and provisioning for lighting interfaces. In one embodiment, a hardware apparatus includes a sensing module to detect a lighting interface from a plurality of lighting interfaces to power a light emitting element, and a dimming module to supply multiple power levels of the lighting interface to the light emitting element. In another embodiment, a hardware apparatus further includes a communication module to provide a signal from a network to the sensing module to detect the lighting interface. A lighting interface may be a digital lighting interface or an analog lighting interface.


Systems, methods, and apparatuses for improved powerline communication (PLC) are described. In one embodiment, a system comprises power down hardware coupled to internal wiring of a premises to selectively power down a portion of the internal wiring on request, and at least one hardware device to transmit a request to the power down hardware to selectively power down a portion of the internal wiring on request and to transmit data using power line communication hardware of the at least one hardware device while the portion of the internal wiring is powered down.

Embodiments of the invention include methods, apparatuses, and systems for processing an image update in a networkable node. An exemplary method comprises initiating an image update process with a node, transmitting an update image to the node, transmitting a confirmation request to determine the node received the update image, upon receiving confirmation the node received the update image, transmitting a switchover command to the node to cause the node to switch from its primary image to the update image, and confirming the switching of the image of the node.

Embodiments of the invention include methods, apparatuses, and systems for processing an image update in a networkable node. An exemplary method comprises initiating (201) an image update process with a node, transmitting (203) an update image to the node, transmitting (205) a confirmation request to determine the node received the update image, upon receiving confirmation the node received the update image, transmitting (209) a switchover command to the node to cause the node to switch from its primary image to the update image, and confirming (211) the switching of the image of the node.


A method implemented in a device is disclosed for networking through signals transmitted across a shared medium network. The method starts with monitoring for a first signal on a shared medium of the shared medium network. The first signal is processed after it is received and while the first signal is being processed, a set of one or more signals is received on the shared medium. Then a set of one or more amplitude increases is determined, where each amplitude increase is from an earlier received signal to a later received signal. The set of one or more amplitude increases is compared to a threshold value and at least partially in response to the comparison, the device discards one or more signals from the first signal and the set of one or more signals.


Techniques for construction of internal controls for improved accuracy and sensitivity of DNA testing include obtaining first data and determining weights over real numbers for a normalization function in less than a day. The first data indicates a measured amount of reference sequences for nucleic acids from training samples. The reference sequences include a target, for which an abundance is indicative of a condition of interest, and covariates not correlated with the condition of interest. The normalization function involves a sum of abundances of the covariates, as internal controls, each multiplied by a corresponding one of the weights. The weights are determined based on minimizing variance of a Taylor expansion of a ratio of a measured amount of the target divided by a value of the normalization function evaluated with measured amounts of the covariates over a portion of the first data in which the condition is absent.


A method is disclosed for detecting packet at a receiving system in a Multi-Carrier Modulation (MCM) system. The method starts with receiving a signal at the receiving system. Then during the plurality of symbol durations, a set of phases of the signal for each symbol duration is obtained, where each phase is a phase of a carrier of the number of carriers. Then a set of phase variances for each carrier of the number of carriers is obtained, where each phase variance is a difference of phases of a carrier in different symbol durations. Then a phase variance value based on the set of phase variances is computed and it is compared with a threshold to determine whether a packet has been detected from the received signal.

Embodiments of the invention include an apparatus for performing Galois multiplication using an enhanced Galois table. Galois multiplication may include converting a first and second multiplicand to exponential forms using a Galois table, adding the exponential forms of the first and second multiplicands, and converting the added exponential forms of the first and second multiplicands to a decimal equivalent binary form using the Galois table to decimal equivalent binary result of the Galois multiplication.


A method is disclosed for detecting packet at a receiving system in a Multi-Carrier Modulation (MCM) system. The method starts with receiving a signal at the receiving system. Then a deviation value of the signal is computed, where the deviation value is computed at least partially based on phase differences between some number of carriers in the preamble. The deviation value is compared with a threshold to determine whether a packet has been detected from the received signal. In response to the determination that a packet has been detected, a symbol offset is computed optionally, where the symbol offset indicates a number of sample points from a beginning of a symbol.
