A self-monitoring tire includes a tire body and a tire pressure sensor. The tire body includes a tread rubber for contact with ground, a bead for coupling to a rim, and a sidewall structure including two portions disposed at opposite sides of the tread rubber, and extending from opposite sides of the tread rubber to the bead. The tire pressure sensor is disposed between respective outward surfaces of the two portions of the sidewall structure, and secured on or embedded in either one of the two portions of the sidewall structure.

In an intelligent monitoring system, a wireless signal processing device transmits a wireless signal toward a first target object in a monitored area, receives a wireless status signal, and generates a monitoring signal corresponding to the first target object according to the wireless status signal. In addition, at least one signal-relaying device receives a back scattering signal, which is reflected from the first target object in response to the wireless signal, transfers the back scattering signal into the wireless status signal, and transmits the wireless status signal to the wireless signal processing device. The signal-relaying device includes a power supply device for supplying power for operations of the signal-relaying device, and the signal-relaying device is disposed in the monitored area between the first target object and the wireless signal processing device.

Intelligent monitoring system and method

An IP camera includes a camera unit for picking up images of a target object; a wireless signal processing unit for transmitting an intelligent monitoring ng a wireless signal to the target object and receiving a scattering wireless signal reflected from the target object; and a signal processing unit electrically coupled to the camera unit and the wireless signal processing unit for receiving a data corresponding to the image of the target object from the camera unit and a data corresponding to the scattering wireless signal reflected from the wireless signal processing unit. The signal processing unit analyzes the data corresponding to the image of the target object to obtain a status ate information and generates a reference signal according to the status information, and the reference signal is processed together with the data corresponding to the scattering wireless signal by the signal processing unit to generate a change detection signal.

The present invention provides a relay-based foolproof circuit for over-voltage protection, which is electrically connected between a plug and an electric device, and includes a relay having at least one magnetic core, a coil wound around the magnetic core and two reed switches each having a reed and being normally in a closed state because of the elastic effect of its reed. The relay-based foolproof circuit is able to provide AC power of a first specification (e.g., 110 V AC power) received from the plug to the electric device. However, when AC power of a second specification (e.g., 220 V AC power) greater than the first specification flows through the coil, the coil causes the magnetic core to generate a magnetic force great enough to drive the two reed switches into an open state for stopping the AC power of the second specification from being provided to the electric device.

A system for managing a community Ethernet switch and apparatus utilizes a network management control circuit for receiving network management packets from the exchange through an independent line and based on the received network management packets for setting a management value of a management information base (MIB) of a simple network management protocol (SNMP) by the SNMP so that the Ethernet switch is capable of monitoring the at least one network interface circuit based on the management value, and transmitting enable or disable signals to a detection loop installed therein based on the management value when the network interface circuit is disabled for performing a loop detection on each network interface circuit, writing a test result into the MIB, and commanding the SNMP to collect the result for transmitting to the exchange for analysis and determination by network management personnel.

System for managing community ethernet switch and apparatus thereof

An ethernet card connected between a host computer and an ethernet includes a transmitting circuit connected between a CPU and a transceiver, a detection circuit connected between the CPU and a MAC (media access control), and an arbitration circuit to arbitrate packet data transmission order between packet data from the CPU to the ethernet and packet data from the host computer to the ethernet, wherein when the ethernet card receives packet data from the ethernet, packet data is received by the MAC through the transceiver and, at the same time the detection circuit is driven by the CPU to detect packet data received by the MAC. As a result the CPU directly drives the MAC to discard received packet data if packet data received by the MAC has nothing to do with the host computer, and the CPU immediately dispatches corresponding packet data to the ethernet through the transmitting circuit and the transceiver if packet data received by the MAC can be directly replied to by the ethernet card.
