  • Patent number: 9703994
    Abstract: Checking of security elements for value documents, which have a plurality of magnetic regions, includes at least a high-coercivity magnetic region having a high-coercivity magnetic material, a low-coercivity magnetic region having a low-coercivity magnetic material, and, where applicable, a combined magnetic region containing both the high-coercivity and the low-coercivity magnetic material. After magnetization of all magnetic materials or the magnetic regions formed therefrom in one direction with a first magnetic field region, only the low-coercivity magnetic material is remagnetized in another direction in a subsequent second magnetic field region. Magnetic signals of the magnetic regions are captured while the security element is still subjected to the second magnetic field region. On the basis of the signals all three types of magnetic region can be reliably distinguished.

    Abstract: A reader for a card having an information strip, the reader comprising a first movable member, a read head capable of reading the information strip, the read head disposed on the first movable member and a second movable member which upon translation causes the first movable member to translate in a direction opposite to the second movable member. The reader includes a guide slot disposed in line with the direction of translation of the second movable element such that when a card is placed in the guide slot and subsequently moved transversely along the guide slot, the card urges the first movable member in the opposite direction and moving the head across the information strip as the information strip is moved in the opposite direction as the read head movement.

  • Patent number: 9380969
    Abstract: Methods and systems are provided that include sampling a light intensity signal at different frequencies based on the waveform of the signal to produce a more accurate digitized signal. The light intensity signal is an analog signal proportional to the intensity of light received at a detector of a pulse oximetry system. In one embodiment, the signal may be sampled exponentially during pulse width periods, such that the end of the pulse width periods where the signal reaches a maximum amplitude may be sampled more frequently. The signal may also be exponentially sampled or oversampled during periods when the signal is expected to near a maximum amplitude. Further, the signal may be sampled less frequently during low amplitude periods of the signal, and during dark periods, such that processing power may be conserved.

  • Patent number: 9361569
    Abstract: A card is provided, such as a credit card or security card, that may transmit information to a magnetic stripe reader via a magnetic emulator. The emulator may transmit the information serially in order to reduce the amount of circuitry needed to emulate a particular block of information. Additionally, for example, a serial encoder may send any amount of information through a single emulation segment. Such a magnetic emulator may be provided on a credit card. A dynamic credit card number may be provided by, for example, coding a number with a different coding scheme for different periods of time. The magnetic emulator may be utilized to transmit a particular coded number for a particular period of time. In this manner, a dynamic credit card number may be provided such that to help secure, and progress, a payment transaction.

  • Patent number: 9347242
    Abstract: A door lock/unlock system for a building automatically controls locking and unlocking of a door. A door lock controller interfaces with an electronic door lock and receives messages including door lock commands from a local receiver. In turn, the local receiver interfaces with a hub device through a mesh network. The hub applies a rule set to make lock operation decisions, and sends messages comprising commands to operate the door lock through the mesh network to the local receiver. The local receiver decodes the messages and passes the commands to the door lock controller to automatically control the electronic door lock. A door state device checks the state of the door. When the checking mechanism indicates that the message was not received or the lock operation failed, the system alerts the user to take appropriate lock action.

  • Patent number: 9311585
    Abstract: A proxy card comprising a swipe speed sensor that detects the speed at which the proxy card is traveling through a magnetic card reader and a microcontroller that uses the swipe speed to adjust a rate at which magnetic stripe data stored in a memory on the proxy card is transmitted to a magnetic stripe emulator on the proxy card is disclosed. The magnetic stripe emulator emulates the magnetic stripe data by generating a magnetic field that changes at the rate at which the magnetic stripe data is received from the microcontroller to ensure that the changing magnetic field is readable by a magnetic stripe reader in the time it takes to complete the swipe. The rate at which the magnetic stripe data is transmitted to the magnetic stripe emulator can be a predetermined multiple of the swipe speed of the proxy card.

  • Patent number: 9299069
    Abstract: Apparatus for electronically notifying an individual of an incomplete transaction associated with a received correspondence item is provided. The apparatus may include a receiver for receiving a single paper correspondence item associated with a first correspondence. The apparatus may include a processor for deriving a digital image from the paper correspondence item. The processor may be configured to determine, based on the derived digital image, whether the correspondence item is a paper check. In response to the determination of the correspondence item as a paper check, the processor may be further configured to use a real-time notification channel to notify the individual of receipt of the paper check. The notification may be based, at least in part, on the identification of the individual. The processor may be further configured to use the real-time notification channel to present at least one option for identification of an account to which the check should be applied.

  • Patent number: 9240208
    Abstract: There is provided a recording apparatus which can effectively execute compression processing regardless of the mixdown level, and which can thereby carry out the mastering process easily. A DSP mixes down audio signals assigned to a plurality of tracks into a stereo audio signal. When performing the mastering process, the DSP uses a peak value detected during the mixdown to adjust a threshold value for the compression processing, and carries out the compression processing using the adjusted threshold value. Subsequently, the DSP performs normalization processing so as to produce a master data, and records the master data in a recorder.
