  • Patent number: 9395562
    Abstract: A method and apparatus for contactless measurement of the characteristics of patients' eyes and eyewear without using any reference device for scaling measurements. The non-contact system comprises of a measurement device having an array of proximity sensors for contactless distance measurement, which is embracing a mobile device having a digital camera, a processor, gyroscope or 3-axis accelerometer sensors, and wireless transceivers. The wireless transceivers support fast and real-time communication between the mobile device and the measurement device. The mobile device is configured to obtain information of distance between the patient face the measurement device at the same time as the digital camera is capturing images of the patient. Such distances assist the processor of the mobile device to re-construct actual eye and eyewear characteristics from the captured image of the digital camera.

  • Publication number: 20160005313
    Abstract: The invention is an augmented stop sign that functions more like a traffic signal light commonly used on road junctions in place of existing passive stop signs. The cost of the stop sign is extremely less than a typical existing traffic signal system at a junction and the time and effort involved in installation and maintenance is similar to that of installing an existing stop sign.

  • Publication number: 20150286075
    Abstract: Described herein is an apparatus and method for characterizing the precise dimensions of a pair of eyeglass frames, including that of the internal setting groove, through a non-mechanical measurement mechanism. The intended spatial resolution in all three orthogonal axes (x, y, & z) is better than 50 microns (millionths of a meter).

  • Publication number: 20150049952
    Abstract: Systems and methods for measuring facial characteristics of patients. In various embodiments, the system uses a geometric pattern to determine a reference scale for an image that includes the geometric pattern and at least a portion of the patient's face. The system may determine the reference scale based at least in part on a known measurement within the geometric pattern. The known measurement may include a distance between two geometric attributes of the geometric pattern. The system may be further configured to correct for errors caused by an orientation of the geometric pattern within the image and/or distortion of the geometric pattern within the image. The geometric pattern may be disposed on a reference device that may be configured to enable a user to attach the reference device to the head of the patient or a pair of eyewear worn by the patient.

  • Publication number: 20150042307
    Abstract: The industry practice to detect and identify objects such as wires, cables, pipes and tuned coils is to inject a known tone from a tone generator into the object by conduction or induction, occasionally with tagging information. The invention is a tone detection apparatus, also known as the tone probe, to detect the presence of such injected tones that makes use of a microphone or audio electrical input of a mobile computer and software application running on the mobile computer such as a contemporary “smart-phone”. The use of a mobile computer reduces the cost of this tone probe and provides the ability to use mobile internet connection to communicate and store the tagging and location information about object under detection. The display of the mobile computer allows providing more information than a typical tone probe.

  • Publication number: 20110215808
    Abstract: A passive electronic marker comprising a single tuned LC circuit, having an inductance and one capacitance element, that respond substantially uniformly to a marker locating instrument irrespective of the orientation the marker was installed in. The inductance is split among more than one electrically contiguous coils; each of the coils is oriented in different axes along the three dimensional space to achieve the substantially uniform response to a marker locating instrument. The tuned circuit is enclosed in a protective housing that may or may not help in the orientation of the marker during burying. The passive marker is of a type that is buried relative to portions of an object for use in locating such objects when necessary.
