A control circuit for a ring oscillator uses an integrator and a comparator. The integrator receives a square wave signal as an input and provides a triangular wave signal as an output. The comparator generates a second square wave signal by comparing the triangular wave signal and a reference voltage. Duty cycle for the ring oscillator can be modulated by varying the reference voltage. For one embodiment of the control circuit, signal frequency of the ring oscillator can be modulated by varying biasing current for the comparator to set slew rate of the comparator. For one embodiment of the control circuit, a resistor and a capacitor form a simple RC circuit for the integrator. For an alternative embodiment of the control circuit, a resistor and an amplifier with a capacitor in a negative feedback loop form an active RC circuit for the integrator. For one embodiment of the control circuit, the comparator is an inverting comparator. A ring oscillator employing the control circuit can be formed using a plurality of inverters coupled in series with the control circuit.

Methods and apparatus for mitigating the effects of interference between multiple air interfaces located on an electronic device. In one embodiment, the air interfaces include a WLAN interface and PAN (e. g. , Bluetooth) interface, and information such as Receiver Signal Strength Index (RSSI) as well as system noise level information are used in order to intelligently execute interference mitigation methodologies, including the selective application of modified frequency selection, variation of transmitter power, and/or change of operating mode (e. g. , from multiple-in multiple-out (MIMO) to single-in, single-out (SISO)) so as to reduce isolation requirements between the interfaces. These methods and apparatus are particularly well suited to use cases where the WLAN interface is operating with high data transmission rates. Business methods associated with the foregoing technology are also described.

Devices and methods for thermal ablation of hypertrophied tissue, such as turbinates, with a resistive heating element adapted for insertion into the tissue. The device uses DC current to heat the resistive heating element, and is operated at relatively low voltage levels and low current levels. The device is easy to operate, and may be applied for predetermined time periods without feedback control, using a timing circuit or computerized control system. The resistive heating element is covered with a thin, non-stick, coating that is thermally conductive, such as Xylan, Teflon or other fluoropolymer or suitable material.

The disclosed embodiments provide a system that facilitates communication with a storage device. During operation, the system provides a physically operated mechanism for enabling detection of the storage device in proximity to a computer system using a discovery protocol. If detection of the storage device using the discovery protocol is enabled, the system uses the physically operated mechanism to establish a wireless peer-to-peer connection between the storage device and the computer system. The system then uses the wireless peer-to-peer connection to transfer a file between the storage device and the computer system.

A system and method for improved wireless communications at a host device (e.g., a portable computing device, a mobile communications device) having multiple wireless communication abilities (e.g., Bluetooth and Wi-Fi). When a component (e.g., a monitor, an Ethernet dongle) having Bluetooth capability is coupled to the host device (e.g., wired or wirelessly), the host device copies its Bluetooth link keys to the component, deactivates its own Bluetooth module and activates (or initiates activation of) the component's. The component's Bluetooth module is operated using a software stack executing on the host device. Thereafter, the component handles Bluetooth operations and the host device communicates with Bluetooth devices via the component. Greater radio isolation is thus provided between antennae used by Bluetooth and Wi-Fi.

A network computer system and method are provided in which each user of a group of users is monitored during a respective online session where the user performs a sequence of M activities, to selectively engage users of the group. A determination is made as to the impact of friction for each user of the group of users with respect to an intention of the respective user, and an action is performed for the user based at least in part on the determined impact of friction.
