A message retrieving system and method for signal collision mitigation and the method thereof are disclosed. The message retrieving system transmits two orthogonal signals over two isolated antenna during a time period that it expects to receive the response. Two virtual channels are artificially created and the collision of response signals originated from the respondents is mitigated.

Message retrieving system with signal collision mitigation and a method thereof

An information broadcasting and interaction system includes: a control device; a Bluetooth smart network connected with the control device, including a plurality of node devices and sense devices, and configured to operate in a mesh mode, a beacon mode, or a deep sleep mode; and a plurality of user devices connected with the Bluetooth smart network. Each node device is configured to relay control and broadcast information or feedback information between the control device and any specific device in the Bluetooth smart network, and to broadcast customized information to the user devices in a predetermined range. Each sense device is configured to collect data with a sensor integrated with the device, and relay the data to the control device.

Information broadcasting and interaction system

A locating and tracking system includes: at least one monitoring device; and a plurality of Bluetooth low energy (BLE) devices acting as either backbone nodes or tracking nodes. The backbone nodes are connected with each other and form a mesh network to relay information to the monitoring device in mesh mode so that the monitoring device knows all the backbone nodes' presence and locations. Each backbone node is further connected with a plurality of tracking nodes to form a sub-network. Within the sub-network, the backbone node is configured to operate in beacon mode to periodically check presence of all the tracking nodes and other compatible BLE devices within its coverage.

Locating and tracking system

An antenna circuit is having an impedance circuit which can cancel signal leakage from the input port into the isolation port of a directional coupler. The antenna circuit further comprises a second impedance circuit for optimizing power transfer from the input port to the output port of the directional coupler. Furthermore, the antenna is tunable in order to maximize the reception strength of the antenna. The antenna circuit provides at once the possibility of tuning the antenna strength, optimizing the power transmission and reducing signal jamming by cancelling signal leakage. The antenna finds use as an effective and miniature RFID antenna.

Antenna circuit and a method of optimisation thereof

The presently claimed invention is to provide a package for compact RF signal system, and a method to form the package thereof in order to miniaturize the size of package, improve signal integrity, and reduce manufacturing cost. The package comprises a hybrid substrate with a sandwiched structure, in which the hybrid substrate comprises an upper layer and a lower layer with different dielectric properties being separated by an interposer for improving electrical isolation and mechanical stiffness. Metal layers are formed on the sidewalls of the opening to surround an active component, such that the metal sidewalls together with two ground plates in the upper and lower layers constitute a self-shielding enclosure inside the package to protect the active component.

Partitioned hybrid substrate for radio frequency applications

The present invention relates to a device with portions of the device on plural substrate surfaces. The device includes a low resistivity substrate having first and second surfaces with a first electrically-conductive device component disposed over a first surface. An intermediate electrically-insulating layer may be disposed between the electrically-conductive component and the low resistivity substrate. A second electrically-conductive component is disposed over the second surface of the low resistivity substrate. A cavity formed in the low resistivity substrate is at least partially filled with a high resistivity material. One or more electrically-conducting pathways are formed in the high resistivity material electrically connecting the first electrically conductive component and the second electrically-conductive component to form a device. Exemplary devices include inductors, capacitors, antennas and active or passive devices incorporating such devices. Vertically integrated device systems can be formed using the device.
