Abstract: Method and system for reading out and writing to RFID-transponders with inductive coupling including a read/write unit with a transmission frequency fs1 defined as a basic transmission frequency and a plurality of transponders operated at a resonance frequency fR. The resonance frequency fR is fixedly predetermined, then for operating conditions with a high distance range, the resonance frequency fR equal to the basic transmission frequency fs1 is selected. For operating conditions with a high recognition rate with a plurality of transponders located within a detection field, the basic transmission frequency fs1 is reduced to a fixed alternative value fs2 . This procedure guarantees reliable communication between the transponders and the read/write unit.

Abstract: A method for preventing a vehicle from deviating from a lane is provided, in which precise determinations of whether a vehicle is deviating from a lane may also be made when driving on curved sections of a road. Using DSRC, which is a system enabling communications between a vehicle and roadside equipment, information of road curvature and lane width is received. This road information and setting information of a camera mounted to the vehicle are then used to determine a lane deviation determination standard angle, which is used in curved sections of the road. A difference between the standard angle and a center value of left and right lane marker angles is compared with a critical value to determine whether the vehicle is deviating from the lane.

Abstract: A response form containing a means of input that on manual influence can switch a conducting electrical circuit connected to an electronic unit (40) incorporated into the response form for registration of the said influence. The present invention provides such a response form at low cost and enables the use of the response form as a patient journal. The patient journal also can be integrated with a pharmaceutical response package. The response package is formed of a disposable material in the form of a sheet (12), and a conducting circuit (26) is printed onto one side (16) of the disposable material. The means of input can consist of circuit makers (30, 32) that are visually marked-on one side of the disposable material and that are arranged to make electrical contact across an interrupted loop (28) of the conducting circuit (26) upon pressing together localized inner surfaces (14, 16) of the disposable material which face each other.

Abstract: A liquid level sensor for conductive liquids having a bias ring to prevent false “full” indications. The sensor is an inexpensive conductive probe that can be installed in any tank or container used to contain a conductive liquid. The build up of residue such as sludge on the inside of the container wall and probe pieces can cause a short between the probe and ground. This situation will result in falsely showing that the level of the liquid being measured is at least at the minimum predetermined requirement even though the actual level may be far less than that amount. The bias ring is a metal ring that is placed around the insulating base of the sensing probe between the probe tip and the top inside of the tank. The probe is then given a charge (positive for negative ground systems) which interrupts the current path between the sensing tip of the probe and ground via the conducting residue. Consequently, the sensor will read correctly despite the conductive residue that may be present.

The EAS device is placed or secured in the recess, the tail is wrapped around a piece of merchandise, and the other end of the tail is affixed to one of the bifolding bodies, and then the bifold is snapped shut permanently. The tag is made out of a tough, minimal stretch plastic such as nylon or another polyamide, enabling the tag to be assembled onto the merchandise simply by looping and snapping, without any riveting or other joining required. Using a tough polymer, the snap fit can be designed to create a permanent attachment so that the tag would have to be cut off or destroyed to remove it.

Abstract: A self-generating light-producing skateboard mainly includes at least one induction coil assembly mounted on at least one wheel supporter assembly, at least one magnet-containing wheel mounted on the wheel supporter assembly at an outer side of the induction coil assembly, at least one light-emitting element fixed to an outer periphery of a deck of the skateboard and electrically connected to the induction coil assembly, and a light-transferring strip mounted around the outer periphery of the deck. When wheels of the skateboard rotate at high speed, the magnets on the magnet-containing wheel interact with the induction coil assembly to produce current that drives the light-emitting element to emit light. The light-transferring strip transfers the light emitted from the light-emitting element to lighten the outer periphery of the deck, making the skateboard safer for use.
