Abstract: A support for the trunk or a limb or joint of a human or animal comprises a first band having first and second end portions with respective fasteners which can be fastened together to fix the band in a loop around the trunk or a limb or joint and at least one pad located inwardly of the first band for engaging a surface portion of the trunk or a limb or joint. The second band has a portion located inwardly of the first band and supports said at least one pad for movement independently of the first band when the first band is fixed to apply pressure to said surface portion. An adjustment means is connected to the second band and extends from an inner side to an outer side of the first band to allow operation outwardly of the first band when the first band is fixed for adjusting the position of said at least one pad.

Abstract: This invention provides neck traction devices wherein a resilient folded biasing body provides a traction force between a shoulder contacting side of the fold and paired head contacting regions. In use, a neck traction is developed when the folded device is applied to a patient with the respective shoulder and head regions contacting the patient's shoulder and head.

Abstract: A game delivery system delivers a plurality of games in a training program. The training program is configured to systematically drive neurological changes to overcome cognitive deficits associated with a neurological disorder. In one embodiment, the training program includes an initial batch of games that predominantly exercise elemental, lower-level cognitive processes and sensory deficits. After a game participant progresses through the initial batch of games, the training program provides games that impose comparatively greater higher-order cognitive processing requirements on the participant. A clinician portal provides remote access to a clinician to data about the game participant's compliance and performance with the training program. The clinician portal also enables the administrator to configure the training program.

Abstract: A new hearing profile assessment plays each of a plurality of frequency tones multiple times at a plurality of loudness levels. For each frequency, the patient indicates which tones that they can hear, establishing minimum-amplitude thresholds for each frequency. The assessment adapts loudness levels until the patient indicates consistent minimum-amplitude thresholds for each frequency. Also, a new system for training the hearing of a subject is disclosed. The system instructs the subject to vocalize various sound items and remember the sounds that they vocalize. The system plays either recorded samples of the subject's own voice, or comparison samples of a synthesized voice or other's vocalizations of the same sound items. The system prompts the subject to compare the played samples with the sounds they remembered vocalizing. The system uses the feedback to adjust sound processing parameters for a hearing aid, cochlear implant, sound output devices, or a training program.

Abstract: In one embodiment, a display device includes a movably suspended diffuser screen, and a voice-coil mechanism coupled to the diffuser screen. A signal-processing device, such as a microprocessor, is coupled to a driver circuit to produce a drive signal at an output terminal for the voice coil in response to a voltage sensed across the voice coil. The driver circuit includes shutdown control to drive its output terminal to a high-impedance state to accommodate sensing voltage across the voice coil. Thus, the signal for the voice coil is produced by the signal-processing device in a closed-loop feedback arrangement without the need for separate position-sensing elements. In a preferred arrangement, a second voice coil is coupled to the diffuser screen and to the signal-processing circuitry to produce a second signal for the second voice coil to accommodate generating a circular motion for the diffuser screen without stationary points.

Abstract: Rapid development of a collaborative database uses a spreadsheet application to implement the database. Each parameter of the database variables is entered into a corresponding cell in the spreadsheet. A first spreadsheet code is entered that refers to selected cells related to a first variable and resolves into database code that instructs a database application to create the first variable in the collaborative database. A second spreadsheet code is also entered also referring to selected cells related to the first variable and resolves into application server (AS) code that instructs an application server to generate a graphical data entry form for that variable. In order to develop the same database and AS code for the remaining variables, the developer uses the autofill function of the spreadsheet to autofill the spreadsheet codes to cells related to the other variables and resolving into their own database and AS codes.

Abstract: In accordance with the teachings of the present disclosure, a system and method for displaying an image are provided. In one embodiment, the method includes receiving a laser through a rotary diffuser. The rotational speed of the rotary diffuser may be continuously varied to reduce the effect of an image artifact in a light pattern. The image artifact may be caused by an imperfection in the rotary diffuser. The light pattern is projected on a display device.

Abstract: Pulses of optical radiation are counted by a pulse counter in a way representative of its effects on tissue. An analog to digital converter digitizes detected optical radiation pulses and an integrator integrates the digitally detected pluses. The integrator has a time constant characteristic sufficient to combine digitally detected pluses that are close enough together so that they are effectively one pulse with respect to tissue exposure limits. The integrator can be programmable to a particular time constant based on a thermal confinement duration of human tissue and wavelength of laser pulses. A counter circuit counts pulses, and a display displays the counted pulses. A capture circuit enables counting the number of pulses occurring within a capture duration by the counter circuit. The analog to digital converter can be configured to a sensitivity.
