A payment card (e.g., credit and/or debit card) or other device (e.g., mobile telephone) is provided with a magnetic emulator operable to communicate data to a magnetic stripe read-head. Gift cards may be inputted by a user into such a payment card or other device such that a user can combine gift cards. Similarly, a user be provided with a global payment account that can be utilized in multiple countries that have different standards for formatting data. A user may be provided with a default country (e.g., United States) but may have a way to select that the user is in a different country (e.g., Japan). Accordingly, a user may select that a Japanese data structure be transmitted through a magnetic stripe reader when the user is in Japan.

An anti-skimming card reader device, and systems and methods for using the same, are provided. The card reading device can include a plate having a first surface and a second surface opposite the first surface. The device can also include a magnetic stripe reader disposed at the second surface. The magnetic stripe reader can include at least one sensor configured to acquire data from a magnetic stripe of a card disposed at the first surface and at least one proximity sensor configured to detect that the card is disposed at the first surface and to cause the at least one sensor to acquire the data from the magnetic stripe.

A method for manufacturing a magnetic core module in a magnetic head, the magnetic core module and the magnetic head. The method for manufacturing the magnetic core module includes: a process for placing a magnetic core group in a holder mold cavity as an insert; and a process for injection-molding in the holder mold cavity. A method for manufacturing the magnetic core module allows the magnetic core group and the holder to be integrally injection-molded with a method of injection molding which uses the magnetic core group as an insert. The method simplifies the process of manufacturing a magnetic head to improve production efficiency, and saves labor and production costs. Further, the method prevents failures such as positional displacement and scattering of magnetic cores, which tends to occur when assembling thin and small magnetic cores, and ensures an ideal yield for a product.

A teleoperable medical system comprises a manipulator arm and a cannula mount coupled to the manipulator arm. The manipulator arm comprises an interface configured to operably couple with a medical instrument. The cannula mount is configured to removably mount a cannula to the manipulator arm in a position to permit removable insertion of the medical instrument through the cannula. The cannula mount comprises a receptacle configured to receive an attachment portion of the cannula in a mounted state of the cannula, and a reader positioned to be in magnetic field sensing proximity to the attachment portion of the cannula in the mounted state of the cannula. The teleoperable medical system comprises a controller configured to receive output signals from the reader and determine identification information about the cannula based on the output signals.

The present disclosure concerns a magnetic reader (MR) sensor device for reading magnetic stripes, the MR sensor device comprising a substrate provided on a wafer, a back-end-of-line (BEOL) interconnect layer and a plurality of magneto-resistive sensor elements embedded within the BEOL interconnect layer; the MR sensor device comprising a protective layer having a Vickers hardness of at least 3 GPa. The present disclosure further concerns a method for manufacturing the MR sensor device. The MR sensor device can be brought close to the surface to the magnetic stripe so that the magnetic stripe can be read with an increased resolution.

Accordingly, a user may select that a Japanese data structure be transmitted through a magnetic stripe reader when the user is in Japan.

An electronic device may include a transmission circuit and an inductive element. The inductive element may be configured to generate a wireless communication signal based on a current. The transmission circuit may be configured to output the current based on a supply voltage; to increase an intensity of the current, from zero to an increased intensity that is less than or equal to a target value, by alternately repeating a first increase and a first decrease of the intensity of the current, in a first time interval; to decrease the intensity of the current, from the increased intensity to zero, by alternately repeating a second increase and a second decrease of the intensity of the current, in a second time interval.

A magnetic secure transmission system includes an inductor, a switching circuit connected to the inductor, and a control circuit. The control circuit controls the switching circuit to adjust a level of a current in the inductor by a first amount over a data transmission period, such that the inductor emits a magnetic pulse including a first magnitude during the data transmission period. The control circuit controls the switching circuit to adjust the level of the current in the inductor such that the level of the current is increased and decreased repeatedly by a second amount between two different levels during a data non-transmission period, and the inductor emits a magnetic pulse including a second magnitude during the data non-transmission period. The second amount is less than the first amount, the first magnitude is greater than a threshold value and the second magnitude is less than the threshold value.

A cannula for insertion of a medical instrument includes a tube portion and an attachment portion coupled to the tube portion. One or more magnets are arranged at the attachment portion and configured to encode identifying information of the cannula. The attachment portion comprises a plurality of encoding positions that each indicate part of the identifying information; and for each encoding position of the plurality of encoding positions, absence of one of the one or more magnets at the respective encoding position indicates a first value, presence of one of the one of the magnets with a first orientation at the respective encoding position indicates a second value, and presence of one of the one of the magnets with a second orientation at the respective encoding position indicates a third value.

An anti-skimming card reader device, and systems and methods for using the same, are provided.
