DETAILED DESCRIPTION

[0049] In FIG. 1, the reference TG denotes a contactless transponder. In this example, the transponder, used in reader mode, is configured to communicate with a figurine FG or an object fitted with another contactless transponder TGF, for example a tag, via its antenna ANT by using a carrier signal having a frequency of for example 13.56 MHz. The figurine or the object may be a statuette, a playing card, a packaging label, or any other object that can be fitted with a transponder

[0050] The transponder TG is in this case a transponder that is capable of communicating in accordance with a contactless communication protocol that uses near-field communication (NFC) technology, for example.

[0051] This transponder TG, incorporated here within a video game device, is for example intended to read characteristics of the figurine that are stored in a memory of the transponder TGF so as to allow the player to play as a character corresponding to said figurine FG.

[0052] This transponder TG comprises an integrated circuit IC, for example an integrated circuit of the ST25 family marketed by STMicroelectronics.

[0053] The transponder TG includes two terminals AC0 and AC1 that are connected, respectively, to the two terminals of the antenna ANT.

[0054] The two terminals AC0 and AC1 in this case form a first contactless communication interface IF1 of the transponder.

[0055] The integrated circuit IC forms a contactless component CMP and also includes processing circuitry MT, including for example an energy recovery circuit, a microprocessor and/or a wired logic unit.

[0056] The processing circuitry MT are in particular configured to process the information received from the transponder TFG of the figurine.

[0057] The transponder TG also includes, as is conventional, an impedance-matching network ADI forming, with the antenna ANT 1, a resonant circuit at the carrier frequency, in this case 13.56 MHz.

[0058] The integrated circuit IC also includes a second communication interface IF2, in this case an I.sup.2C interface linked, by an I.sup.2C bus, referenced BS, to a processing unit external to the integrated circuit, referenced MCU, for example a microcontroller. As is conventional, the microcontroller MCU is the master device on the bus BS, and the communication interface IF2 is a slave device.

[0059] The microcontroller MCU is used in particular to manage and to control the video game.

[0060] A memory means MM is coupled between the processing circuitry MT and the second communication interface IF2.

[0061] The transponder TG is here a dynamic transponder acting as a gateway for the transmission of information from the figurine to the microcontroller MCU.

[0062] In other applications, the transponder TG may also act as a gateway for the transmission of information from the microcontroller MCU to another contactless device.

[0063] In NFC technology, information or data are generally transmitted in the form of frames, as is the case for example for the Type A protocol of the ISO-14443 standard.

[0064] The exchanged frames contain headers, data bits and parity bits.

[0065] The processing circuitry MT are therefore configured to extract, on reception, the data from the frames received from the figurine FG so as to write them to the memory means MM.

[0066] The microcontroller MCU is then configured to read these data from the memory means MM via the second communication interface IF2.

[0067] The transponder TG and the microcontroller MCU are borne by a printed circuit board bearing the reference PCB2.

[0068] The printed circuit board PCB2 is housed in a device DIS (FIG. 2), here a video game device.

[0069] This device DIS here takes the form of a controller handset possessing a housing 1 having an upper face 10 from which a control element 2 protrudes.

[0070] FIG. 3 shows an overall view of the control element 2.

[0071] It includes a base 20 and a joystick 21 that is articulated to and coupled to the base 20 so as to allow the movement of a character for example or the movement of a cursor on a screen, for example a screen of the video game device itself or a television screen for example, to be controlled. The joystick 21 may be referred to as a control member.

[0072] As will be seen in greater detail below, the control element 2 also includes a printed circuit board that is connected, by a connector 23, to the printed circuit board PCB2.

[0073] As illustrated in greater detail in FIG. 4, the base 20 of the control element includes here two lugs 201 and 202 that allow the base to be secured to the printed circuit board PCB2.

[0074] The base also includes a cavity 200 within which the joystick 21 articulates.

[0075] As illustrated in greater detail in FIG. 5, the joystick 21 includes a shaft 210 having a lower end 211 that cooperates with the cavity 200 in the base for the articulation of the joystick in three dimensions. The lower end 211 may be referred to as a first end of the joystick 21.

[0076] The joystick also includes, opposite the lower end 211, a free end, which is circular in shape, possessing here a groove 2120 covered with a cover 2130. The free end may be referred to as a second end of the joystick 21.

[0077] Additionally, as will be seen in greater detail below, this groove 2120 will house for example the antenna ANT of the transponder TG.

[0078] Lastly, as illustrated in greater detail in FIG. 6 and as mentioned above, the control element 2 includes a printed circuit board PCB1 that is connected to the printed circuit board PCB2 by the connector 23.

[0079] Reference is now made more particularly to FIG. 7, which schematically illustrates one exemplary configuration of the antenna ANT.

[0080] As mentioned above, the antenna ANT is housed in the groove 2120 that is located at the free end of the joystick 21.

[0081] This free end protrudes from the top of the housing 1 of the handset.

[0082] In the example illustrated here, the antenna ANT is circular and comprises a plurality of turns.

[0083] By way of nonlimiting indication, the diameter of the antenna is for example 1.6 cm. Its resistance at 13.56 MHz is 1 ohm and it has an induction value of about 500 nH.

[0084] Since the antenna ANT is located in the control element, it is away from the metal elements of the game device, thereby improving contactless communication while avoiding the use of ferrite sheets. Furthermore, using an element of the game device that is already present (the joystick) to house the antenna provides a cost saving.

[0085] The control element 2 includes here two first electrically conductive linking means 212 and 213. These two means 212 and 213 are, for example, metal tracks leading into the shaft 210 of the joystick 21 of the control element 2. The electrically conductive linking means 212, 213 may be referred to as electrical connectors.

[0086] These two metal tracks possess two first ends 214 and 215, respectively.

[0087] These two first ends 214 and 215 are connected, respectively, to the two terminals BA1 and BA2 of the antenna ANT.

[0088] The two tracks 212 and 213 further possess two second ends 216 and 217 that are located opposite the two first ends 214 and 215.

[0089] The device then further comprises two second electrically conductive linking means 24 coupling the two second ends 216 and 217 to the impedance-matching circuit ADI.

[0090] In the example described here, the second linking means 24 includes flexible connecting means 240, possessing here two flexible cables 2400, 2401, that are connected between the two second ends 216 and 217 and metal tracks 242 and 243 of the printed circuit board PCB1, these metal tracks 242 and 243 being connected to the interface IF1 of the board PCB2 and consequently to the impedance-matching circuit ADI of the transponder TG. The flexible connecting means 240 may be referred to as a flexible connector.

[0091] As shown more precisely in FIG. 8, the two second ends 216 and 217 may be provided with female and male connectors 216C and 217C. The female connector 216C has a first shape configured to receive a corresponding male connector with a second shape, and the male connector 217C has a third shape configured to receive a corresponding female connector with a fourth shape.

[0092] As illustrated in FIG. 9, the flexible connecting means 240 may themselves be fitted with a male and female connector 2430 that is intended to cooperate with the connectors 216C and 217C. The flexible connecting means 240 further include, at the other end, another connector 2420 that is intended to be connected to the printed circuit board PCB1 so as to cooperate with the metal tracks 242 and 243. The female connector 2430 has a first shape configured to receive a corresponding male connector with a second shape, and the male connector 2430 has a third shape configured to receive a corresponding female connector with a fourth shape.

[0093] Of course, the length of the flexible connecting means 240 is chosen so as to maintain an electrical connection while not hindering the movement of the joystick articulated to its base.

[0094] FIG. 10 is another schematic view showing the connection of the flexible connecting means 240 to the printed circuit board PCB1 and the metal tracks 242 and 243 that route to the printed circuit board PCB1.

[0095] The disclosure is not limited to the embodiments that have been described, but encompasses all variants.

[0096] Thus, as illustrated in FIG. 11, it would be possible for the flexible connecting means 2400 and 2401, which are connected to the two second ends 216 and 217 of the first linking means, to be connected to electrically conductive securing screws 250 and 251. These securing screws allow the base 20 to be secured to the control element at the site of the lugs 201 and 202 (FIG. 4) and they come into contact with the metal tracks 242 and 243 so as to make an electrical connection from the antenna to the impedance-matching circuit.

[0097] Furthermore, although only one antenna has been shown, it would be possible for the handset 1 to include a plurality of antennas located, respectively, within a plurality of protruding elements. These antennas would then be connected in parallel and all linked to the impedance-matching circuit.

[0098] Furthermore, although the game device has been shown in this exemplary embodiment in the form of a handset, it would of course be possible for the device to include a console that is distinct from the handset including the control element.

[0099] The game device could also have a plurality of controller handsets.

[0100] The control element could also be a control button protruding from the housing of the controller handset.

[0101] The various embodiments described above can be combined to provide further embodiments.

[0102] These and other changes can be made to the embodiments in light of the above-detailed description. In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled. Accordingly, the claims are not limited by the disclosure.
