摘要:
A method and apparatus of establishing a connection between a wireless device and a second device includes maintaining a state of the connection between the wireless device and the second device, and receiving an indication that a wireless link to the wireless device has been lost or may be lost. In response to the receiving the indication that the wireless link to the wireless device has been lost or may be lost, the state of the connection is transitioned from a first state to a second state.
摘要:
Apparatus and methods for ultrasonic coupling using ultrasonic radiation pressure generating are provided. Ultrasonic energy is generated to propagate in the form of ultrasonic waves in a medium coupled to a second element. The ultrasonic energy is converged in the medium to couple the medium to an object located at a distance from the second element. Additional apparatus and methods are disclosed.

A service for searching for unsolicited communications is provided. For example, the service may inspect e-mail messages, instant messaging messages, facsimile transmissions, voice communications, and video telephony, and analyze these communications to determine whether an intended communication is unsolicited. In connection with voice and video telephony, a voice sample may be obtained from the caller and voice recognition may be performed on the sample to determine an identity of the person or the voice. The voice sample may also be used to determine the type of voice—i.e., if the voice is live, machine generated, or prerecorded. Where the call is a video telephony call, image recognition may be used to inspect an image of the person. The information obtained from voice recognition, voice type recognition, and image recognition may be used to detect whether the messages if from a known source of unsolicited communications.

摘要:
Apparatus and methods are disclosed involving a linear actuator motor such as a voice coil motor, including a driver for the motor, powered by a power supply. A failure of one or more of the power outputs of the power supply used by the linear actuator motor and the driver is determined. Alternatively, or in addition thereto, energy in the linear actuator motor outside a predetermined range is determined. The power supply or the power supply outputs are caused to shut down based on the failure of the power outputs and/or energy determined in the linear actuator motor.

Apparatus and methods for ultrasonic coupling between a coupling fluid and an object using micro surface tension and capillary effects are provided. The apparatus may include a chamber comprising a wall, a bottom, and a fluid inlet. The fluid inlet may allow a fluid to enter the chamber. Portions of the wall may have a number of slits with dimensions that allow a controlled overflow of the fluid to hold a top surface of the fluid in a stable contact with the object when the fluid is flowing into the chamber. The object may be located at a distance from the top of the wall. Additional apparatus and methods are disclosed.

摘要:
A Fresnel Annular Sector Actuator (FASA) for micromixing of fluids, utilizes a self-focusing acoustic wave transducer which focuses acoustic waves through constructive wave interference. In the transducer, RF power is applied between the electrodes (sandwiching a piezoelectric film) with its frequency preferably corresponding to the thickness mode resonance of the piezoelectric film. Strong acoustic waves are generated over the electrode area, and interfere with each other as they propagate in the fluid. By proper design of the electrodes, and forming various combinations of the electrodes, wave focusing can be achieved. The mixing can be further enhanced by providing selective actuation and sequencing of the different segments by an RF signal source.
