摘要:
A lighting system (100) including at least one controller (102) and a memory (104) containing program portions which configure the controller (102) to obtain weather forecast information including one or more of current and expected weather conditions over a period of time; determine one or more lighting settings based upon the weather forecast information; form lighting setting information in accordance with the determined lighting settings; and transmit the lighting setting information. The system (100) may include an illumination source (106) to provide illumination in accordance with the lighting setting information The system may change characteristics (e.g., illumination pattern, illumination intensity, illumination spectrum, illumination polarization,) of the illuminated source (106). The process may form lighting setting information to control one or more filters (130) in accordance with a desired lighting setting.
摘要:
Light management system for an outdoor lighting network (OLN) having lighting units, the system including a central control apparatus (40); lighting unit control apparatus (50); and a communication system (60). The central control apparatus (40) is operable to receive a configuration request; receive optimization objectives/constraints; identify the lighting units operably connected to the plurality of lighting unit control apparatus (50) associated with the configuration request; determine whether at least one of lighting requirements, illuminance model, and cost model have changed; update the lighting requirements, the illuminance and the cost model when at least one of the lighting requirements, the illuminance model, and the cost model have changed; optimize operation of the identified lighting units as a function of the optimization objectives/constraints, the lighting requirements, the illuminance and the cost model; and send an operation instruction to the lighting control apparatus (50).
摘要:
A method (400) for creating a group shared distributed reservation in a wireless network. The method comprises collecting information about the distributed reservation availabilities of devices in the wireless network (S410); selecting a group of shared devices to be included in the group shared distributed reservation based on the collected information (S420); sending a reservation request to each device in the group of shared devices (S430); and updating the group of shared devices to include only devices that accept the reservation request (S460), thereby creating a group shared distributed reservation of medium access time slots.
摘要:
A medical system includes one or more MBAN devices that acquire and communicate patient data. The medical system further including one or more medical body area network (MBAN) systems, each MBAN system including the one or more MBAN devices that communicate the patient data with a hub device via short-range wireless communication, the communication of the patient data via the short-range wireless communication being within a predefined spectrum. The hub device receives patient data communicated from the one or more MBAN devices and communicates with a central monitoring station via a longer range communication. The one or more MBAN devices transmit an association request to the hub device on one or more auxiliary channels to associate each MBAN device with the MBAN system, the auxiliary channels being outside the predefined spectrum.
摘要:
A policy-based OLN (outdoor lighting network) light management system including a central control apparatus (40); lighting unit control apparatus (50); a communication system (60) operably connecting the central control apparatus (40) and the lighting unit control apparatus (50); and a repository (70) in communication with the central control apparatus (40), the repository (70) being operable to store an OLN policy. The central control apparatus (40) is operable to: receive a policy; check the policy for consistency against the OLN policy; determine attributes and configuration commands for each of the lighting unit control apparatus (50) in accordance with the policy when the policy is consistent with the OLN policy; and communicate the attributes and the configuration commands for each of the lighting unit control apparatus (50) to a corresponding one of the lighting unit control apparatus (50).
摘要:
A centralized frequency agility technique is employed in conjunction with a plurality of medical body area network (MBAN) systems (10, 35, 36), each of which comprises a plurality of network nodes (12, 14) intercommunicating via short range wireless communication. A central network (20, 22, 23, 24) communicates with the MBAN systems via longer range communication that is different from the short range wireless communication. A central frequency agility sub-system (40) is configured to communicate with the MBAN systems. The central frequency agility sub-system receives current channel quality information for a plurality of available channels for the short range wireless communication, and allocates the MBAN systems amongst the available channels based at least on the received current channel quality information.
摘要:
A method (300) for improving quality of service of a wireless link between a source device and a destination device by forwarding frames on an alternate path between the source device and destination device. The method comprises selecting by the source device at least one forwarding device to be included on the alternate forwarding path; constructing a medium access control (MAC) forwarding frame (200) to include at least an address of the at least one forwarding device (S310); and transmitting the MAC forwarding frame to a forwarding device next to the source device (S320).
摘要:
A method (300) for performing link adaptation of wireless links in a wireless network. The method comprises generating a first enhanced link adaptation (ELA) information element (100) by the transmitter (S310); sending the first ELA information element to at least one receiver (S320); upon reception of a second ELA information element at the transmitter, determining optimal transmission parameters for the transmitter, wherein the second ELA information element is generated and sent by the at least one receiver in response to the first ELA information element (S370).

摘要:
A method and system is provided for transmitting data frames from a first device to a second device in a wireless network. The method includes concatenating a plurality of data frames (303) into an aggregated frame (100) by the first device; transmitting the aggregated frame (100) from the first device to the second device; validating each of the plurality of data frames (303) individually by the second device; and retransmitting each of the data frames (303) that contains an error by the first device, without retransmitting the data frames that are valid.
