RFID buckle closure and presence sensor system for safety childseat

In the preferred embodiment of the present invention a passive, wireless, RFID-based wireless buckle-closure sensor determines whether the buckle of a child safety seat is secured. Sensors also are provided to determine if the child is in the seat, the temperature and if the vehicle is in operation, and alarms are sounded if an unsafe condition is detected by the system. Child safety seats utilize a 3-point or 5-point locking-mechanism for seat belt and harness restraints. The locking-mechanism requires that metal belt / harness components latch together and are released by depression of a lock-mounted release button. In the preferred embodiment of the present invention a passive RF transponder is affixed to the buckle. Essentially the RF transponder comprises an RFID device without a data component. The RF transponder is interrogated by a frequency-scanning reader, which determines the resonant frequency of the transponder. The resonant frequency of the transponder is affected by the presence of the metal fittings local to the RF transponder. Thus, since the major components of the buckle and latch are metal, the detection of the change in the resonant frequency of the transponder, also referred to as “detuning,” permits the determination of the state of the belt / harness buckle—latched or unlatched. This sensing is wireless, unobtrusive, and requires only a passive component be attached to the buckle. Further disclosed is a method of determining the status of a child in a child safety seat, including: whether or not a child is in the seat, whether or not the belt / harness buckle is latched, whether the vehicle's engine is in operation, and whether or not the surrounding temperature exceeds the temperature range. If an unsafe condition is detected, an alarm is activated.

Network server emergency information accessing method

InactiveUS8116723B2Emergency connection handlingDevices with sensorAutomated crash notificationNetwork service
A Means and Methods for providing a PSAP with means for tracking the real time location of a wireless telephone that connects to an Internet server upon detection of predefined events or reception of a command from a person to do so and transmits location information and event data to said server for viewing by authorized users. The server also displays a telephone number for a PSAP having jurisdiction over the location of the wireless telephone. Said PSAP telephone numbers being stored in a server data base and providing a means whereby a person logged-onto the server can call this PSAP telephone number, explain the reason for the call, provide the call taker with log-on information allowing access to the server and the data transmitted from the wireless telephone so that he can access mapped location information showing the location of the wireless telephone and then take appropriate action. Methods for delivering vehicle Automatic Crash Notifications to a PSAP, for establishing VoIP communications with crash victims and for providing crash data and video information to emergency responders showing the injury level of crash victims is disclosed as well as a video security system with multiparty command dialed PSAP notification voice calls and audio, video and location data transmission to the server. Satellite security telephones, offender monitoring devices, child safety telephones and medical alert notification embodiments of the invention are also disclosed.

Seat cushion adjusting mechanism of integrated automobile safety seat for children

The invention discloses a seat cushion adjusting mechanism of an integrated automobile safety seat for children, which comprises a seat cushion height adjusting mechanism and a seat cushion length adjusting mechanism, wherein the seat cushion height adjusting mechanism is installed below the middle seat cushion of the back-row seats, and the middle seat cushion of the back-row seats can be lifted by a driving device and a link mechanism, so that the seat for adults can be changed into a heightened seat for children; and the seat cushion length adjusting mechanism is connected with multiple sections of additional seat cushions which can be connected with or separated from each other at the front side of the seat cushion of the seat, so that the length of the seat cushion can be adjusted according to the body sizes of the children. The invention can realize the stepless adjustment of the seat cushion height based on the height of the children and the multistep adjustment of the seat cushion length, thereby protecting the children from being hurt in the process of automobile collision when being used by matching with the traditional three-point safety belt for adults. Besides, the invention can be adjusted to adapt to adults for use, has the advantages of simple structure, low cost and convenient use, and can realize the intelligent positioning of the children.
