Publication number: 20130085370Abstract: In systems and methods for generating cross-linking activity in an eye, a feedback system monitors a biomechanical strength of the eye in response to the photoactivation of a cross-linking agent applied to an eye. The feedback system includes a perturbation system that applies a force to the eye and a characterization system that determines an effect of the force on the eye. The effect of the force provides an indicator of the biomechanical strength of the eye. The characterization system determines the effect of the force on the eye by measuring an amount of deformation caused by the force or a rate of recovery from the deformation.Type: ApplicationFiled: October 2, 2012Publication date: April 4, 2013Applicant: Avedro, Inc.Inventor: Avedro, Inc.

Patent number: 8403862Abstract: A method includes directing toward a portion of a subject's body a first pulse of electromagnetic energy. While the portion is in a functional state due to the first pulse, a second pulse is directed toward the portion. At a second-pulse time, reflected energy due to the second pulse is detected. While the portion is in a functional state due to the first and second pulses, a third pulse is directed toward the portion. At a third-pulse time, energy of the third pulse, reflected from the portion, is detected. In response to detecting the pulses at the second-pulse time and the third-pulse time, a characteristic of the portion is quantified resulting from (a) the functional state due to the first pulse and (b) the functional state due to the first and second pulses. A clinical state of the subject is identified. Other embodiments are described.Type: GrantFiled: December 22, 2008Date of Patent: March 26, 2013Assignee: Yeda Research and Development Co. Ltd.Inventors: Amiram Grinvald, Darin Nelson, Harel Primack

Publication number: 20130057829Abstract: Various embodiments of a device for performing a gaze field sobriety test are disclosed. The device includes a housing. A light source is affixed in or on the housing. The light source generates light during at least a portion of the gaze field sobriety test. A speaker positioned in or on the housing generates sounds during at least a portion of the gaze field sobriety test. A power source is coupled to the speaker and the light source. An input is positioned on the housing. The input is selectable by a test administrator to initiate an audible sound through the speaker at a predetermined time interval during at least a portion of the gaze field sobriety test. The audible sound provides an indication to the test administrator during the gaze field sobriety test to assist in proper performance of the gaze field sobriety test.Type: ApplicationFiled: November 2, 2012Publication date: March 7, 2013Applicant: ENFORCEMENT INNOVATIONSInventor: Enforcement Innovations

Patent number: 8379871Abstract: A personalized hearing profile is generated for an ear-level device comprising a memory, microphone, speaker and processor. Communication is established between the ear-level device and a companion device, having a user interface. A frame of reference in the user interface is provided, where positions in the frame of reference are associated with sound profile data. A position on the frame of reference is determined in response to user interaction with the user interface, and certain sound profile data associated with the position. Certain data is transmitted to the ear level device. Sound can be generated through the speaker based upon the audio stream data to provide real-time feedback to the user. The determining and transmitting steps are repeated until detection of an end event.Type: GrantFiled: May 12, 2010Date of Patent: February 19, 2013Assignee: Sound IDInventors: Nicholas R.
