Publication number: 20140194770Abstract: An apparatus and a method are provided for the treatment of soft tissue. The apparatus includes a light source and at least two optical assemblies. Each of the optical assemblies includes at least one optical element and a light-transmitting contact surface configured to transmit a substantially uniform distribution of light therethrough. The apparatus further includes at least two optical transmission devices each disposed between the light source and a corresponding one of the at least two optical assemblies. The apparatus also includes a handpiece to which the at least two optical assemblies are attached, and which is adapted to bring the light-transmitting contact surfaces of the at least two optical assemblies in contact with soft tissue disposed therebetween.Type: ApplicationFiled: March 13, 2014Publication date: July 10, 2014Applicant: Gradiant Research, LLCInventor: Kathleen McMillan

Publication number: 20140194771Abstract: An implantable device for estimating neural recruitment arising from a stimulus, has a plurality of electrodes. A stimulus source provides stimuli to be delivered from the electrodes to neural tissue. Measurement circuitry obtains a measurement of a neural signal sensed at the electrodes. A control unit is configured to control application of a selected stimulus to neural tissue using the stimulus electrodes; and after the selected neural stimulus, apply a probe stimulus having a short pulse width. A remnant neural response evoked by the probe stimulus is measured; and the control unit estimates from the remnant neural response a neural recruitment caused by the selected neural stimulus.Type: ApplicationFiled: May 11, 2012Publication date: July 10, 2014Inventors: John Louis Parker, James Hamilton Laird, Dean Michael Karantonis

Publication number: 20140194772Abstract: A device for measuring a neural response evoked by a stimulus. First and second sense electrodes are positioned at distinct locations along a neural pathway. A neural stimulus is applied and first and second recordings of a neural response evoked by the stimulus are obtained from the respective sense electrodes. The first recording and the second recording are compared to determine propagation properties of the evoked neural response.Type: ApplicationFiled: May 11, 2012Publication date: July 10, 2014Applicant: Saluda Medical Pty. Ltd.Inventors: Peter Scott Vallack Single, James Hamilton Laird

Publication number: 20140194773Abstract: Apparatus, systems and methods employing contact lens with capacitive sensors are provided. In some aspects, a contact lens includes: a substrate; a capacitive sensor, disposed on or within the substrate, that senses a capacitance on the contact lens; and a circuit disposed on or within the substrate. In some aspects, the circuit can include a capacitance analysis component that determines a condition of an eyelid associated with the eye over which the contact lens is disposed and/or a parameter associated with the eye over which the contact lens is disposed. In some aspects, the condition can be a blink of an eyelid. In some aspects, the parameter can be at least one of a pressure of an object in proximity to the contact lens, a thickness or type of a layer of material disposed on or within the contact lens or a composition of material on the contact lens.Type: ApplicationFiled: September 23, 2013Publication date: July 10, 2014Applicant: GOOGLE INC.Inventors: Nathan Pletcher, Brian Otis

Publication number: 20140194774Abstract: A system for administering a hearing test to a remotely located user or subject using a user computing device connected to a communication network. The system provides for testing of ambient noise at the remote location and accuracy of sound reproduction by headphones engaged to the user computing device in a calibration of the loudspeakers of the headphones and the venue prior to communicating the test sounds. The calibration insures results determined by user input provide an accurate outcome.Type: ApplicationFiled: January 10, 2013Publication date: July 10, 2014Inventor: Robert Gilligan

Publication number: 20140194775Abstract: A system and method are provided for capturing hearing characteristics from self-administered hearing tests, including loudness tolerance levels at different sound frequencies, as an individualized shaped auditory profile for automatically enhancing audio to complement and address as closely as possible an individual's hearing deficits experienced via a particular signal pathway, the signal pathway including the audio device used to administer the test, the sound environment, and the user's hearing capabilities. The user may self-administer a hearing test on a convenient personal apparatus, such as a smartphone. The shaped auditory profile may then be used to produce enhanced sound subsequently transmitted to the individual via the same signal pathway. In certain of its aspects, the invention is useful for any individual seeking an enhanced hearing experience, whether having hearing within normal range or hearing that is impaired.Type: ApplicationFiled: January 9, 2014Publication date: July 10, 2014Inventors: Charles Andrew VAN HASSELT, Chi Shan Anna KAM, Pui Tong Paul LEE, Ka Kui CHENG
