A charging system for a peripheral device, such as a stylus, including orientation control. The charging system includes charging circuitry and magnets. The magnets are configured so that they attract the peripheral device to an engagement surface when it is in a first orientation relative to the engagement surface so that charging circuitry in a peripheral device portion couples with charging circuitry in a charger portion. The magnets are configured so that they also repel and rotate the peripheral device when it is in a second orientation relative to the engagement surface.

Charging system including orientation control

A machine implemented method includes alternately energizing multiple transmit coils in a first device, receiving indications of received signal strength at receive coils in a second device, selecting a first pair of coils including a first transmit coil and a first receive coil having the greatest received signal strength, and transferring energy from the first transmit coil to the first receive coil.

Receive and transmit coil pair selection

Methods of RFID tag assembly include affixing an antenna to an integrated circuit (IC) by forming one or more capacitors coupling the antenna and the IC with the dielectric material of the capacitor(s) including a non-conductive covering layer of the IC, a non-conductive covering layer of the antenna such as an oxide layer, and/or an additionally formed dielectric layer. Top and bottom plates of the capacitor(s) are formed by the antenna traces and one or more patches on a top surface of the IC.

RFID tag assembly methods

RFID tags are assembled through affixing an antenna to an integrated circuit (IC) by forming one or more capacitors coupling the antenna and the IC with the dielectric material of the capacitor(s) including a non-conductive covering layer of the IC, a non-conductive covering layer of the antenna such as an oxide layer, and/or an additionally formed dielectric layer. Top and bottom plates of the capacitor(s) are formed by the antenna traces and one or more patches on a top surface of the IC.

Radio Frequency Identification (RFID) tags are provided, along with apparatuses and methods for making. In some embodiments, the RFID tags include an RFID tag chip that is attached to an inlay and/or a strap. The inlay or strap has one or more contact bumps formed thereon. In some of these embodiments, the RFID tag chip includes pads for electrical contacts, but not chip-bumps, thanks to the contact bump.

RFID tags with bumped substrate, and apparatuses and methods for making

A precursor for a Radio Frequency Identification (RFID) tag includes a conductive lead frame with at least three segments, an RFID Integrated Circuit (IC) with at least two antenna terminals, and at least two jumpers. The RFID IC is mounted on at least one of the segments. The antenna terminals are electrically coupled to at least two of the segments, and the jumpers electrically couple the segments such that the coupled segments form a two-turn coil between the antenna terminals of the RFID IC.

A single sideband radio system. The system comprises a transmitter and a receiver. The transmitter comprises a transmitter baseband processing portion for generating a first baseband signal comprising first, second, and pilot components and modulating the first baseband signal in inverse proportion to the strength of the first component of the first baseband signal and an RF output stage for generating and transmitting a single sideband signal comprising first, second, and pilot portions corresponding to the first, second, and pilot components of the modulated first baseband signal. The receiver comprises an RF input stage for receiving the single sideband signal and a receiver baseband processing portion for generating a second baseband signal comprising first, second, and third components corresponding to the first, second, and third portions of the single sideband signal and for correcting the second baseband signal based on the pilot component of the second baseband signal.
