Mitscherlich PartmbB

The present invention proposes an RF enabled lighting system unit, such as e.g. a sensor or a LED driver. The unit comprises an essentially RF antenna integrated in a wall or behind it of a casing of the unit, and a spacer element arranged on top of the RF antenna and made from an non RF signal attenuating material, wherein the spacer element is configured to prevent direct contact between the RF antenna and an external building element made from a RF signal attenuating element.

The present invention provides a luminaire comprising: a casing; a driver disposed within said casing, configured to provide electrical power to the luminaire; lighting means disposed within said casing, configured to emit light upon receiving power from the driver; and at least one RF antenna module with directed transceiving characteristic attached to or integrated with said casing. The antenna is configured to enable communication between the luminaire and an external building device or network.

An optical element (30) for influencing the light of a light source (15) is a louvre, which is formed by a grid-like arrangement of a plurality of reflector cells (31), each of which forming a ring-like wall (32) with a reflective surface, which extends from a light entry opening (33) of the associated reflector cell (31) to a light exit opening (34) of the reflector cell (31) The reflector cells (31) form at least one row (31<1>, 31<2>,31<3>) extending in a longitudinal direction, wherein lateral sections of the walls (32) of at least some reflector cells (31), with respect to the longitudinal direction have a reduced height compared to perpendicular portions of the wall (32) or form a translucent section.

This application provides a method and an apparatus for discovering an edge service. The method includes: A first network element receives first information, where the first information includes first service information. The first network element receives second information, where the second information includes first domain name information. When the first domain name information corresponds to the first service information, the first network element determines, for a first terminal device, an application server that is the same as that of a second terminal device or an application server in an edge network that is the same as that of a second terminal device. The first network element sends a first rule to indicate a second network element to send first application server address information to the first terminal device, or the first network element sends a third rule, where the third rule includes second option information, and the second option information is used by a DNS server to determine application server address information. The method provided in this application can be used to determine a same application server or an application server in a same edge network for terminal devices belonging to a same terminal group, and reduce an interaction delay between the terminal devices in the terminal group.

An information providing method for providing information to a work-related person including any one of a worker who performs work on a work site, a supervisor who supervises the worker, a manager of the work site, and an owner of the work site, the information providing method comprising: acquiring a state of the work site; generating display information to be displayed on display means (304) of a terminal (30), used by the work-related person, based on the acquired state of the work site; and displaying the generated display information on the display means.

Embodiments of this application provide a data processing method and apparatus, to scramble, by using one interleaver or one LDPC tone mapper, a bit sequence of a bitstream of a user to whom a plurality of RUs are allocated, so that hardware costs are reduced. The method includes: allocating a coded bitstream of a first user to M RUs or a first RU including M RUs, where the M RUs or the first RU is an RU allocated to the first user, and M is a positive integer greater than 1; reordering all bits in the coded bitstream by using a first interleaver or a first tone mapper.

A method and an apparatus for predicting a high frequency excitation signal are disclosed. The method includes: acquiring, according to a received low frequency bitstream, a set of spectral frequency parameters that are arranged in an order of frequencies, where the spectral frequency parameters include low frequency LSF parameters or low frequency ISF parameters; for the set of spectral frequency parameters, calculating a spectral frequency parameter difference (102) between every two spectral frequency parameters that have a same position interval in some or all of the spectral frequency parameters; acquiring a minimum spectral frequency parameter difference (103) from the calculated spectral frequency parameter differences; determining, according to a frequency bin that corresponds to the minimum spectral frequency parameter difference, a start frequency bin (104) for predicting a high frequency excitation signal from a low frequency; and predicting the high frequency excitation signal (105) from the low frequency according to the start frequency bin. By implementing this embodiment, a high frequency excitation signal can be better predicted, thereby improving performance of the high frequency excitation signal.

This application discloses a message processing method and a related apparatus. In the message processing method, a terminal device receives a first push message of a first application that is sent by a push server; the terminal device receives a second push message of a second application that is sent by the push server; the terminal device displays the first push message and the second push message on a first user interface; the terminal device receives a first input operation performed by a user on the second push message; and the terminal device displays a second user interface in response to the first input operation, where a display form and/or a display sequence of the second push message on the second user interface are/is different from a display form and/or a display sequence of the second push message on the first user interface. In this way, an operation of querying a push message can be simplified, and user experience can be effectively improved.
