A method of read magnetic stripe card(s) into a database, to select a specific card from the database, and to output the data related to that specific card to existing merchant card reader equipment with no modification. A simulated magnetic stripe card can be tethered to a cell phone via the headset jacks. A more complex design uses an un-tethered, simulated magnetic stripe card by including BLUETOOTH (or other wireless) communications on the card. This dual purpose invention is intended to eliminate the need to carry multiple magnetic stripe cards in a wallet or purse by consolidating all of the individual card information into a form to be reproduced onto the simulation card when needed by the user. It can also be used at a merchant POS card reader to allow an existing MSD reader to be converted to use in wireless cell phone transactions e.g. BLUETOOTH or NFC.

A video holographic display device operates so that the size of a reconstructed three dimensional scene is a function of the size of the hologram-bearing medium; the reconstructed three dimensional scene can then be anywhere within a volume defined by the hologram-bearing medium and a virtual observer window through which the reconstructed three dimensional scene must be viewed. This contrasts with conventional holograms, in which the size of the reconstructed scene is localised to a far smaller volume and is not a function of the size of the hologram-bearing medium at all.

In a method for operating a radar system, the object is to determine by simple means and at low cost the distance and / or the radial velocity of at least one target object with high resolution. For this purpose, in each measuring phase of the measurement process in the "pulse FMCW radar system", switchover between a transmission mode and a receiving mode is effected a multiple number of times and at short intervals of time. In the transmission mode, all receiving units of the radar system are switched off, while a pulse-shaped (frequency-modulated) transmission signal with time-successive transmission pulses having a specific pulse-on time and a specific carrier frequency is emitted from at least one transmitter unit of the radar system. In receiving mode, all transmitter units are switched off in the pulse-off times of the transmission pulses, while from at least one receiver unit all reflection signals originating from the last emitted transmission pulse are detected as received signal from the entire observation range before emission of the next transmission pulse. The distance and / or the radial velocity of the reflection objects is determined indirectly by the signal processing unit of the radar system by evaluation of the frequency difference and / or phase difference between the transmission signal and the received signal.

The invention discloses a touch panel, a display panel, a display device and a fingerprint identification method. The touch panel comprises a substrate, a plurality of fingerprint identification units arranged on the substrate, and an encapsulation layer covering the plurality of fingerprint identification units; and the fingerprint identification units include light-emitting devices and light-sensitive devices. In addition, the touch panel also includes optical path restricting structures arranged above all the light-emitting devices. Because of the optical path restricting structures arranged above the light-emitting devices, light emitted by the light-emitting devices is transmitted in the optical path restricting structures in a total reflection manner.

Most of light is irradiated on the light-sensitive devices corresponding to the light-emitting devices, so that the crosstalk of light received by the light-sensitive devices in different identification units is avoided and thus accurate fingerprint identification is realized.

The invention discloses a method for controlling channel access of a wireless sensor network. A base station node and each sensor node adopt a time frame structure with different lengths of time frame, so that the sensor nodes can reserve different time slots by dispatching to carry out data packet transmission, thereby not only reducing collision probability of forwarding data packets among sensor nodes in a high-density monitoring area and improving the utilization rate of wireless channel, but also effectively avoiding overhearing in the wireless sensor network and frequent status switching of a transceiver; therefore, the sensor nodes can be in dormancy status as fully as possible during idle transmission so as to greatly reduce energy consumption under the high-loading network condition and have good energy efficiency. A path reserve mechanism can reserve a multi-hop time slot in advance along data packet forwarding direction in time slot reservation phase, according to the time frame synchronizing characteristics of the sensor nodes on a forwarding path, thereby effectively avoiding end-to-end transmission delay of single data packet caused by intermittent transmission of data packets on the forwarding path.
