Abstract:
A disposable tool suitable for use in orthopedic alignment comprises a sensor (101) communicatively coupled to the wand (102) to register points of interest on a first and second bone and transmit location data related to the points of interest to the sensor (101) to assess orthopedic alignment with the points of interest. A display via a wireless connection to the tool reports and visually displays alignment information in real-time. The wand (102) and the sensor (101) each have at least two ultrasonic transducers. The wand (102) has a housing fits in a hand and includes a tip (134) for identifying and registering a location. The wand (101) can be attached to a mount in a predetermined position within the surgical field during a portion of the alignment procedure. Sensor (101) and wand (102) remain within the surgical field throughout the surgery and are disposed of after use in surgery.
Abstract:
An acoustical sensor can include a fabricated surface that produces an acoustical sound signature responsive to a finger tapping on the fabricated surface, and a microphone within proximity of the fabricated surface to analyze and associate the acoustical sound signature with a user interface control for operating a mobile device or earpiece, for example, to adjust a volume, media selection, or user interface control. The microphone can include an ultra-low analog circuit to set a capacitance and establish a frequency response, the analog circuit programmable to identify a direction of a directional touch or localized touch on the fabricated surface. The analog circuit by way of a floating gate can control a real delay between a front and back diaphragm to control microphone directivity. Other embodiments are disclosed.
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:
An earpiece (100) and acoustic management module (300) for in-ear canal echo suppression control suitable is provided. The earpiece can include an Ambient Sound Microphone (111) to capture ambient sound, an Ear Canal Receiver (125) to deliver audio content to an ear canal, an Ear Canal Microphone (123) configured to capture internal sound, and a processor (121) to generate a voice activity level (622) and suppress an echo of spoken voice in the electronic internal signal, and mix an electronic ambient signal with an electronic internal signal in a ratio dependent on the voice activity level and a background noise level to produce a mixed signal (323) that is delivered to the ear canal (131).
Abstract:
An apparatus for virtual navigation and voice processing is provided. A system that incorporates teachings of the present disclosure may include, for example, a computer readable storage medium having computer instructions for processing voice signals captured from a microphone array, detecting a location of an object in a touchless sensory field of the microphone array, and receiving information from a user interface in accordance with the location and voice signals.
Abstract:
A method and device for media searching based on touchless finger signs (312) and gestures (313) is provided. The device (100) can include a controller element (110) that receives a search string from a touchless sensing device and presents at least one media (412) that corresponds to at least a portion of the search string. The media can include audio, image, video, and text selections (326). The search string can include at least one alpha-numeric character generated in a touchless sensory field of the touchless sensing device.
Abstract:
A method for using an earpiece (800) in a work environment is provided. The earpiece (800) attenuates sound from the work environment to the user's ear. The earpiece (800) includes an ear canal microphone (820) for measuring a sound pressure level in an ear canal of the user. Sound pressure levels are measured periodically while in the work environment. Each measured sound pressure levels is stored in memory (127) of the earpiece with time and location information. The sound pressure level information is downloaded to a database (1704) when the earpiece is removed from the user ear for recharging. The sound pressure level information is analyzed and any potential noise compliance issues in the work environment are identified.
Abstract:
At least one embodiment is directed toward one or more disposable devices suitable for use in a surgical field of an operating room. One device includes a sensor communicatively coupled to a wand to register points of interest on a first or second bone of a muscular-skeletal system and transmits location data related to the points of interest to the sensor to assess orthopedic alignment with the points of interest.
Abstract:
An earpiece (100) and acoustic management module for in-ear canal suppression control are provided. A method for suppressing signals for a conference call, a vehicle, and a general communication event is also provided. The earpiece can include an Ambient Sound Microphone (111) to capture ambient sound, an Ear Canal Receiver (125) to deliver audio content to an ear canal, an Ear Canal Microphone (123) configured to capture internal sound, and a processor (121). The processor can generate a voice activity level (622) and suppress an echo, spoken voice, and media content in the electronic internal signal, and mix an electronic ambient signal with an electronic internal signal in a ratio dependent on the voice activity level and a background noise level to produce a mixed signal (323) that is delivered to the ear canal (131).
Abstract:
At least one exemplary embodiment is directed to a method and device for voice operated control with learning. The method can include measuring a first sound received from a first microphone, measuring a second sound received from a second microphone, detecting a spoken voice based on an analysis of measurements taken at the first and second microphone, learning from the analysis when the user is speaking and a speaking level in noisy environments, training a decision unit from the learning to be robust to a detection of the spoken voice in the noisy environments, mixing the first sound and the second sound to produce a mixed signal, and controlling the production of the mixed signal based on the learning of one or more aspects of the spoken voice and ambient sounds in the noisy environments.
