Abstract: Various examples relate to a wired local area network (WLAN) including a shared transmission medium. An apparatus includes a beacon counter and an operational mode controller. The beacon counter is operably coupled to a line of a shared transmission medium of a wired local area network. The beacon counter is to count beacon signals on the line and determine a beacon count over a predetermined time period, or a beacon rate of the beacon signals. The operational mode controller is to control the apparatus to take over operation as a master node of the wired local area network based, at least in part, on a maximum bus cycle length of bus cycles on the line and responsive to the beacon count or the beacon rate.

Abstract: Various embodiments relate to a wired local area network (WLAN) including a shared transmission medium (e.g., a 10SPE network). A method may include detecting an event in a WLAN including physical level collision avoidance (PLCA). The method may also include disabling a beacon of a first node operating as a master of the WLAN in response to the event. Further, the method may include enabling a second node to operate as the master of the WLAN.

Abstract: Disclosed embodiments relate, generally, to traffic shaping at a network segment having a shared bus. Some embodiments relate to performing aspects of the traffic shaping at a physical layer device. In some cases, transmit timeslot signaling may be tuned at a physical layer device to create transmit timeslots that are aligned with the traffic shaping profile.

Abstract: Various embodiments relate to wired local area networks. A method may include detecting, at a node in a wired local area network, at least one event. A physical layer device of the network node is configured to implement a physical level collision avoidance (PLCA) sublayer. The at least one event may include at least one of an amount of data stored in a first-in-first-out (FIFO) buffer of the node being at least a threshold amount, and a received packet being a precision time protocol (PTP) packet incurring variable delay. The method may further include emulating a collision at the node in response to the at least one detected event.

Abstract: Synchronization for audio systems and related systems and circuitry are disclosed. An audio system includes a word select line of a digital audio interface, a serial clock line of the digital audio interface, and hardware circuitry. The hardware circuitry is configured to provide a word select signal to the word select line and a serial clock signal to the serial clock line. The word select signal is configured to indicate channels of a serial data signal provided to a serial data line of the digital audio interface. The hardware circuitry is also configured to synchronize the serial clock signal to a clock reference stream of an audio stream communicated via a network interface.

Abstract: A microcontroller includes a packet matching circuit, a hardware timer circuit, and a processor. The packet matching circuit is configured to match contents of received packets to the microcontroller and identify whether a packet has been received. The hardware timer circuit is configured to provide a synchronization timestamp based on a signal from the packet matching circuit that a synchronization packet has been matched, and provide a follow-up timestamp based on a signal from the packet matching circuit that a follow-up packet has been matched after reception of the synchronization packet. The processor is configured to adjust a clock base to determine a synchronized clock base based upon the synchronization timestamp and upon the follow-up timestamp.

Abstract: A glass container inspection machine is disclosed for inspecting glass stippled bottles for defects. Stippled bottles are supported at an inspection station and are illuminated with a light source. The stippled bottle is imaged a pixel matrix with the pixels of the image varying in intensity from bright to gray at the points of stippling. A computer evaluates the pixels of the image including a look up table for values to be assigned to specific light intensities from light to black, the plot of the look up table having a high gain portion from black to gray and a continuous low gain portion from gray to white.
