Abstract: A camera is integrated into eyeglasses to allow hands-free recording of video or still images. The eyeglasses also include electronic components, such as a processor for encoding the video and a radio for transmitting the video. The eyeglasses may stream the video to a server, where the video may be viewed my other users. The eyeglasses may connect to a cellular data network to stream the data or connect to a nearby mobile device that relays the streaming video to the cellular data network. The size of the eyeglasses with the integrated camera may be reduced by overmolding wiring and/or electronic components into temples of the frame and coupling components with the integrated camera through the temples and the front frame of the eyeglasses.

Abstract: A ballast including an inverter circuit for providing an oscillating power signal for energizing at least one lamp. The inverter circuit includes a first transistor having a first gain and a second transistor having a second gain, each configured for alternately operating between a conductive state and a non-conductive state. The power signal has a waveform cycle comprising a first pulse generated when a first transistor operates in a conductive state, and a second pulse generated when the second transistor operates in a conductive state. The integral value of the first pulse of each waveform cycle of the power signal is different from the integral value of the second pulse of each waveform cycle such that a differential relationship between the first gain and the second gain is greater than or equal to a minimum value in order to minimize lamp striations.

Abstract: A spinal treatment system for treating a spinal region of a patient's back includes a harness configured to be coupled to a preselected location on the patient. A force transfer member is coupled to the harness and is configured to transfer force to the harness. A vibrational movement head is controlled by a computer and is configured to apply a preselected laterally vibrating force to the force application member extending therefrom. A vertical displacement member is coupled to the computer and is configured to move the vibrational movement head to a preselected vertical displacement relative to the patient.

Abstract: A modality system that computes a signal having a first tension level, a second tension level, and transition tension levels between the first and second tension level, where the higher of the first and second tension levels includes an oscillation. The system communicates the signal to an electromechanical actuator to apply a modality treatment to a patient.

Abstract: A spinal treatment apparatus for applying a force to a patient includes a base portion, a telescoping support, a spinal distraction device and an actuator. The telescoping support is mounted on the base portion and includes a bottom member and a top member. The top member is engaged with the bottom member so that the top member has a retracted position and an extended position. The telescoping support is capable of withstanding a force, corresponding to the spinal treatment force, imparted on the top member, while in both the retracted position and the extended position. The spinal distraction device is mounted on the top member and applies the spinal treatment force to the patient. The actuator moves the top member vertically relative to the bottom member.

Abstract: A spinal treatment system for applying a preselected force regimen to a spine of a patient includes a treatment bed, having a head end and a foot end, is configured to support the patient. A harness is configured to transmit force to a portion of the spine of the patient. A cable having a first end is coupled to the harness and is configured to apply force to the harness. A matrix head is coupled to the cable and is configured to apply a force, having a force magnitude and a force direction, to the cable, so that the force direction varies along more than one axis. A vertical displacement drive is disposed adjacent to the foot end of the treatment bed and is configured to support the matrix head and to displace the matrix head along a vertical axis. A computer is programmed to drive the vertical displacement drive and the matrix head.

Abstract: An ultrasound system for imaging an object using data received from an ultrasound transducer employs a first touch screen configured to display ultrasound images and to receive control inputs relating to the images. A second touch screen is configured as a user input device. A processor is coupled to the ultrasound transducer so as to receive data therefrom. The processor is also coupled to the first touch screen and to the second touch screen. The processor is configured to generate ultrasound images based on the data received from the ultrasound transducer. The processor is also configured to cause the first touch screen to display the ultrasound images. The processor is also configured to receive control input data from the first touch screen and the second touch screen.

Abstract: A mechanism for mapping an anatomical characteristic of a patient includes a treatment bed having a top surface. A fiber Bragg grating channel is disposed along at least a portion of the treatment bed near the top surface and includes a fiber optic waveguide defining a plurality of spaced-apart Bragg-type gratings. A multi-wavelength light source generates a beam that is in optical communication with the fiber Bragg grating channel. A detector, in optical communication with the fiber Bragg grating channel, detects reflections of light from at least one of the Bragg-type gratings. A computer is programmed to calculate at least one anatomical characteristic based on a characteristic of at least one of the reflection of light.
