Methods and apparatus for monitoring nutrition, especially fermentation in a rumen of a ruminant, wherein a characteristic value of carbon dioxide inside the rumen and/or reticulum is determined.

A device that is capable of determining its relative position with regard to another device. The device accomplishes this by receiving and analyzing two sets of information emitted by the device whose unique identifier and relative position is to be determined. The first set of information received by the device includes a structured light pattern with a known geometric configuration reflected off a surface in view of both devices. The second set of information received by the device includes a digital communication signal that encodes the unique identifier of the emitting device. Both sets of information may be transmitted on a free space optical communication channel that can be non-directed and non-line of sight.

A transceiver dongle enables signal penetration into a building. The transceiver dongle includes an interface for connecting the transceiver dongle with a processing circuit that provides a received RF signal. A signal processing chipset converts the received RF signals to a format that overcomes losses occurring when the RF signals penetrate a structure of the building over a wireless communications link. Transceiver circuitry converts between the RF signals and signals in the format that overcomes losses occurring when the RF signals penetrate the structure of the building as controlled by the signal processing chipset. An antenna transmits and receives the signals in the format that overcomes losses from the transceiver circuitry between the transceiver dongle and a second transceiver dongle.

An approach is described for a method for a base station in a fifth generation (5G) wireless c01mnunication or a new radio (NR) system that includes the following steps. The method includes determining base initial seeds and a time parameter. The method further includes generating actual initial seeds based on the base initial seeds and the time parameter; generating a Pseudo-Noise (PN) sequence based on one of the actual initial seeds; and generating a remote interference management reference signal (RIM-RS) sequence based on the PN sequence. The method further includes transmitting the RIM-RS sequence to a remote base station.

An access device constructs a beacon frame, where the beacon frame includes a newly added field, and the newly added field represents multiple data guard interval lengths supported by the access device. The access device broadcasts the beacon frame, so that a terminal selects an available guard interval length matching a data guard interval length supported by the terminal from the beacon frame, and performs data communication with the access device by using the available guard interval length. Data communication between the access device and the terminal can be implemented when the access device supports multiple data guard interval lengths.
