Wireless devices, systems and approaches or methods having the capability of determining the location of a given wireless device. An example system includes a wireless device that generates at least one pulse as a part of an output signal, and the at least one pulse is captured by anchor devices and used, in a time of arrival approach, to determine the location of the example device. The at least one pulse may be generated during a designated portion of an otherwise normally modulated message. Another example system includes an anchor node that generates a directional output signal, the direction output signal including data indicating its direction, and the directions of output signals from plural anchor nodes when pointed at a wireless device are used to determine the location of the wireless device. Combinations of the pulse and directional antenna systems, devices used within each of these systems, and approaches associated with these systems are also included.
Low-Power Wireless Inflatable Bladder Damper For Forced Air Heating, Ventilation, And Air Conditioning Systems
A low-power, wireless, inflatable bladder damper device for controlling the flow of air through an airflow channel, and a method of operation for the same. Rather than requiring power supply and/or control wiring for operation of a wireless damper device, a low-power inflatable bladder damper device that requires no external wiring for operation can be used. A completely wireless damper device can reduce the cost of installation of damping devices in airflow channels, as well as the complexity of installation, while at the same time providing improved control of airflow throughout an airflow system.

International Classification:
H04B 7/212 H04J 3/06
US Classification:
455502, 370324, 370503, 370507
Abstract:
A wireless system having an infrastructure node and several leaf nodes in a non-redundant version or having at least two infrastructure nodes and several leaf nodes in a redundant version. Leaf nodes may individually seek out timing information in order to be in synch with an infrastructure node. Upon receipt of synch information from an infrastructure node, the respective leaf node may send data to the infrastructure node. In the case of a redundant system, primary and secondary nodes may be selected from a list of infrastructure nodes. Communications between an infrastructure node and a leaf node may occur on one of a number of channels, and the channel may be changed for communications between the nodes. In the case of a redundant system, a single transmission from the leaf node is received simultaneously by the redundant infrastructure nodes.

International Classification:
H04J 3/06
US Classification:
370350, 370328, 370338, 455502
Abstract:
A system includes multiple wireless nodes forming a cluster in a wireless network, where each wireless node is configured to communicate and exchange data wirelessly based on a clock. One of the wireless nodes is configured to operate as a cluster master. Each of the other wireless nodes is configured to (i) receive time synchronization information from a parent node, (ii) adjust its clock based on the received time synchronization information, and (iii) broadcast time synchronization information based on the time synchronization information received by that wireless node. The time synchronization information received by each of the other wireless nodes is based on time synchronization information provided by the cluster master so that the other wireless nodes substantially synchronize their clocks with the clock of the cluster master.
