Embodiment Construction

[0029] Turning now to the drawings, embodiments of the present disclosure provide methods and corresponding devices for confirming whether a peripheral device worn by a user is sufficiently close to (ie, within a predetermined distance of) the user's wireless communication device. Thus confirmed, the user's wireless communication device can safely perform a predetermined security function using data and information transmitted by the peripheral device, such as transitioning from a locked state to an unlocked state.

[0030] figure 1 is a perspective view illustrating system 10 constructed in accordance with one embodiment of the present disclosure. System 10 includes a wireless communication device (shown here as a smartphone 70 ) and a peripheral device (which in this embodiment is a "wristband" 90 worn on the wrist by a user). Typically, both the smartphone 70 and the wristband 90 communicate with each other via a two-way communication link 14, which, as described in more d...

Abstract

A system including a wireless communication device and a peripheral device communicate with each other using radio frequency (RF) waves that are propagated using a user's own body as a transmission medium. The wireless communication device selectively controls the transmit output power of the peripheral device to cause the peripheral device to transmit data and information in a low-power transmission mode. This minimizes the amount of RF waves that are received at the wireless communication device as reflected RF waves, but helps to ensure that the RF waves that do reach the wireless communication device are transmitted as surface waves along the user's skin. Responsive to the receipt of the surface waves, and based on a validity of the information carried by those surface waves, the wireless communication device transitions from a locked state to an unlocked state.

Description

technical field [0001] The present disclosure relates generally to transmit power control of a remote device, and more particularly to a wireless communication device that controls transmit power of a peripheral device to enable communication between two devices. Background technique [0002] There is currently an emerging consumer market for a specific class of wearable peripherals that serve as companion products to smart devices. Their popularity can be traced in part to the various features they offer. Such devices include, for example, rings, necklaces, eyeglasses, and "wristbands" (eg, watches or wristbands) that are worn around a user's wrist. [0003] One feature provided by these wearable devices allows the wearable device to be used as a personal token to automatically access a locked smartphone. In particular, a wearable device worn by a user may transmit a code or token to the user's smartphone, allowing the user to bypass manual entry of a predetermined unlock...
