A system and method including a disposable wearable device that provides enhanced capabilities to a non-wearable device for a limited period of time by sensing proximity and securely exchanging permissions with the non-wearable device. In one embodiment, the wearable device is capable of sensing one or more bio-signals that are provided to the non-wearable, tactile feedback, or the like. The wearable device may be disposable and may also provide additional tactile feedback for the extended feature (e.g. game feedback, etc). In another embodiment, the wearable device is capable of sensing one or more bio-signals that are provided to the non-wearable, tactile feedback, or the like.

The present invention provides a method of calculating certain body and mental rhythms, and then using this information to indirectly determine the state (flow, body and mental rhythms) which is also reflective of balance between the sympathetic and parasympathetic portions of the autonomic nervous system of the user. By calculating the HRV real time including High Frequency components of the heart information, and for example determining the flow by multiplying the Heart Rate frequency with the Heart Rate Variability, a new method for determining a user state is invented. It is efficient and effective method to use less power within a faster response time for determining such a state. It is applicable in the frequency and time domain.

In one aspect, an example system includes an arrow nock configured to couple to an arrow, a transmitter coupled to the arrow nock, and a controller. The controller is configured to (i) determine that the arrow has been shot from a bow and (ii) responsive to determining that the arrow has been shot from the bow, cause the transmitter to transmit a beacon signal at a variable rate that varies based on an amount of time elapsed since determining that the arrow has been shot from the bow.

A smart wearable device with sensors that can acquire biological input about the user as well as environmental data is presented. Theses sensors can acquire sensor input which causes the smart wearable device to identify a required task to perform. If the smart wearable device determines that the task can only be performed properly by acquiring new capabilities, the smart wearable device can automatically acquire the necessary capabilities from various data sources and configure itself to perform the task properly.

A method of using access control devices to send event notifications and to detect user presence includes receiving a notification of an event. The receiving is at an access control device in a wireless mesh network and the notification is initiated by an originating computer. The access control device is at a geographic location. The notification of the event is broadcasted at the access control device. An indication of a presence of a user at a mobile device within proximity of the access control device is received at the access control device. The receiving is in response to the broadcasting and to an action of the user at the mobile device. The indication of the presence of the user and the geographic location is transmitted to the originating computer via the wireless mesh network.
