A method of selectively commissioning a node device by a coordinator device in a network created by the coordinator device is disclosed. The coordinator device and the node device interact with each other to check and confirm that a coordinator temporal indication related to a commissioning start time recorded by the coordinator device and a node temporal indication related to a commissioning start time recorded by the node device are the same or temporally very similar or close to each other. Then the coordinator device will commission the node device by joining the node device into the network created by the coordinator device. The ensures that only wanted or expected node devices will be joined into the network created and managed by the coordinator device.

An adaptive balancing mechanism of dual-head cement trowelling machine includes a water tank, a screw support base, an adjusting screw, a sensor and controller, a counterweight, a stepper motor, an underframe, a guide rail, a guide rail support plate, limit plates, and a transmission member. The controller collects the weight change information of the water in the water tank in real time according to the operation process. Adjust the position of the counterweight in real time by the stepper motor and the adjusting screw to make the two trowel heads in adaptive dynamic balance to the ground pressure.

The prevent invention discloses a defrosting machine column fixed support with an inclined flat leg, including a defrosting machine (), a connecting support (), a pedestal bolt (), and a pedestal (). The connecting support () includes an anti-tilting guide barrel (), a fixed pillar (), a rib plate (), and a connecting plate (). The pedestal () includes a pedestal plate () and a flat leg (). The pedestal bolt () is used for fixedly connecting the connecting support () with the pedestal (). The pedestal plates are hit into the soil so as to solve digging difficulties and low efficiency of a small diameter mounting deep hole with high accuracy requirements; each pedestal plate is respectively vertically provided with two intersecting flat legs in an inclined mode, thus balancing forces in each direction and stabilizing the defrosting machine column. The holes on the pedestal plates can integrate the soils on the inner side and outer side and two sides into one body, thus stabilizing the defrosting machine. In addition, the connecting support is employed, and standard tubes replace conventional non-standard tubes, thus saving on material cost, and transport and storage are also convenient. The support is simple in structure, convenient to implement, can be applied on pebbled land, not only reduces labour intensity when mounting, but also improves the anti-sinking, anti-horizontal torsion and anti-tilting abilities of the defrosting machine column, improves defrosting machine work reliability, and improves mounting efficiency and economic benefits of the defrosting machine.

The invention relates to a method for transmitting information, particularly network parameters for connecting to a wireless network, from a provisioning device to a wireless device via a wireless interface. The information is obtained in an encoded form in the provisioning device and the provisioning device transmits a sequence of data packets () in accordance with a pattern generated based on the encoded information. Each element of the pattern correspond to a predetermined time distance between consecutive data packets () or to a predetermined data packet length, and the data packets () have a length which is smaller than a maximum length supported by the wireless interface.

Provisioning a wireless device without keypad

A method of operating a wireless communication system is disclosed. The method includes receiving respective downlink transmissions at N second transceivers from a first transceiver, where N is a positive integer greater than 1. The reception acknowledgement signals by the N second transceivers are combined into a single reception acknowledgement signal and transmitted to the first transceiver.

HARQ design for high performance wireless backhaul

A method of operating a wireless communication system is disclosed. The method includes receiving first and second parallel data streams. The first data stream is converted to a first frequency-domain data stream by a discrete Fourier transform (DFT) having Nsize, where Nis a positive integer. The second data stream is converted to a second frequency-domain data stream by a DFT having Nsize, where Nis a positive integer. The first and second frequency-domain data streams are mapped to respective subcarriers.

This invention generally relates to interference mitigation, and more specifically to interference mitigation in wireless communications networks. The proposed solution takes advantage of the clear channel assessment (CCA) function used by WLAN networks. Hence, by jamming the interfering WLAN channel during a predetermined time period, the interfering WLAN network is forced to withhold transmissions on the WLAN interfering channel during a backoff period of time. The solution of the subject application makes use of this backoff period to enable a WPAN network to transmit critical information such as, but not limited to, a request for changing the current working frequency.

A mesh WLAN controller () operates in mesh soft-access-point or mesh client modes. When operating in the mesh client mode it performs a mesh network scan, for detecting at least one mesh WLAN BSS (), send mesh client access requests to mesh WLAN BSSs detected, and, if mesh client access is achieved, provide information indicative to the accessed WLAN BSSs of any other mesh WLAN BSS to which mesh client access is achieved, and if mesh client access is not achieved with any of the detected mesh WLAN BSSs, operate in the mesh soft-access-point mode. Upon receiving an instruction to operate in a mesh bridge-client mode, the controller detects messages from any of the mesh WLAN BSSs () with mesh client access, and forwards the received mesh WLAN messages within any other of the mesh WLAN BSSs to which mesh client access has been achieved.
