Abstract:
A system and method for is provided for operation of an orthopedic system. The system includes a load sensor for converting an applied pressure associated with a force load on an anatomical joint, and an ultrasonic device for creating a low-power short-range ultrasonic sensing field within proximity of the load sensing unit for assessing alignment. The system can adjust a strength and range of the ultrasonic sensing field according to position. It can report audible and visual information associated with the force load and alignment. Other embodiments are disclosed.
Abstract:
At least one exemplary embodiment is directed to a website configured to collect sound signatures from around the world and beyond. A communication device automatically stores acoustic information received by a microphone of the communication device. The acoustic information is analyzed for a trigger event. The trigger event stores the acoustic information, attaches metadata, creates a Gaussian Mixture Model, and measures sound pressure level. The communication device automatically sends the sound signature to a database when a communication path is opened to communication device. Each sound signature has associated metadata including a time stamp and geocode. Automatically collecting sounds using a communication device adapted for the process enables a database that captures sounds globally on a continuous basis.
Abstract:
A portable measurement system is provided comprising a probe, two trackers, a receiver and a pod. A user interface control captures a location and position of the probe in a three-dimensional sensing space with respect to a coordinate system of the receiver from time of flight waveform analysis. The system suppresses a ringing portion of the received ultrasonic and minimizes distortion associated with ultrasonic transducer ring-down during high-resolution position tracking of the probe and the two trackers. Media is presented according to a customized use of the probe and two trackers during an operation workflow.
Abstract:
A spine alignment system is provided to assess load forces on the vertebra in conjunction with overall spinal alignment. The system includes a spine instrument having an electronic assembly and a sensorized head. The sensorized head can be inserted between vertebra and report vertebral conditions such as force, pressure, orientation and edge loading. A GUI is therewith provided to show where the spine instrument is positioned relative to vertebral bodies as the instrument is placed in the inter-vetebral space. The system can distract vertebrae to a first height and measure the load applied by the spine region. The GUI can indicate that the load is outside a predetermined range. The spine region can be distracted to a second height where the load is measured within the predetermined load range.
Abstract:
A system and method of touchless interaction is provided for resolving a pivot point of an object where direct placement of a sensor at the pivot point is not practical. It applies to situations where the pivot point of a rigid object is inaccessible but remains stationary, while the other end is free to move and is accessible. The system maps the object's pivot point by way of an external sensor that detects constrained motion of the rigid object within a hemispherical banded boundary. It can also detect a geometric pattern and acceleration during the constrained motion to compensate for higher order rotations about the pivot point. Other embodiments are disclosed.
Abstract:
A mobile communication environment (100) can include a mobile device (160) to measure and send sound pressure level data. The mobile device (160) can initiate the collection of audio information responsive to detecting a trigger event. Mobile device (160) can measure or calculate the sound pressure level from the audio information. Metadata including time information and geographic location information can be captured with the collected audio information. Mobile device (160) can send the sound pressure level data and metadata through a wired or wireless communication path to a database (614).
Abstract:
One embodiment of a sterile networked interface system is provided comprising a hand-held surgical tool and a data processing system. The surgical tool includes a sensor for sensing a physical variable related to the surgery, a wireless communication unit to transmit the physical variable to the data processing system, and a battery for powering the hand-held surgical tool. The surgical tool sends the physical variable and orientation information responsive to a touchless gesture control and predetermined orientation of the surgical tool. Other embodiments are disclosed.
Abstract:
A touchless sensing unit (110) and method (200) for operating a device via touchless control is provided. The method can include detecting (210) a finger (310) within a touchless sensory space (101), and handling (220) a control of the device (100) in accordance with a movement of the finger. A first finger movement can be recognized for acquiring a control, and a second finger movement for selecting a control. The method can include estimating (230) a location of the finger in the touchless sensory space for acquiring the control, and identifying a finger movement (250) of the finger at the location for selecting the control.
Abstract:
A method for determining position and alignment is provided. The method includes monitoring a first and second sequence of ultrasonic signals transmitted from the first device to a second device, estimating a location of the first device from Time of Flight measurements of the ultrasonic signals at respective microphones on the second device, calculating a set of phase differences, weighting a difference of an expected location and estimated location of the first device with the set of phase differences to produce a relative displacement, and reporting a position of the first device based on the relative displacement.
Abstract:
A method (400) and device (100) for touchless control of an headset or earpiece is provided. The device can include a sensing unit (202) for determining (402) a presence of a finger within a proximity of the earpiece, tracking (404) a touchless movement of the finger in air within the proximity, selecting (410) the control in accordance with a movement of the finger, and adjusting (414) the control in accordance with the tracking. A circular movement of the finger can be tracked for scrolling through a list. Menu options in the list can be audibly played during the scrolling.
