International Classification:

H04J 312

US Classification:

370352, 370524, 379 9301

Abstract:

A number of proposals have been developed to provide data communications over two-wire copper circuits at rates equivalent to a number of combined ISDN B-channels. For example, for an ISDN rate digital subscriber line (IDSL), the circuit between the network termination at the customer premises and the channel bank carries data on two combined B-channels. An IDSL circuit cannot carry voice communications. Some such services carry the lower rate signaling D-channel only on the subscriber line circuit. Normal ISDN services carry voice services on one of the two B-channels, limiting data communications to the other B-channel. Normal ISDN services do carry the lower rate D-channel through the network, but this channel is used only for call set-up signaling, low speed data communications and the like. The invention uses two or more B-channels on the DSL circuit for data communications and transports voice telephone communications on the low speed signaling D-channel. The bearer (B) channels typically connect to a high speed data network, such as SMDS, for services such as Internet access.

David Gavin Hunter - Towson MD, US

International Classification:

G09F001/04

US Classification:

4012401, 4012403

Abstract:

An improved greeting card is presented that incorporates cellular bubble material, such as bubble wrap, into the images and or text thereon. The bubbles of the cellular bubble material may be popped, thereby providing an amusing and pleasurable activity for the recipient of the card. By making reference to the popping activity, the message on the card may be reinforced. The cellular bubble material provides pleasing visual and tactile features, and if used in quantity provides integral protection of the card and its contents.

Abstract:

A patellofemoral brace consisting of a sleeve adapted to be worn by a user in the knee area and having a patella interior opening is provided with a glide which is adjustably carried by the sleeve and which includes a patella engaging brace pad which may be silicon filled and which is generally U-shaped having one longer leg and one shorter leg. The brace is used to influence proper positioning of the patella by the generation of a force applied to the superolateral aspect of the patella to correct misalignment of the patella.

Assignee:

Children's Medical Center Corporation - Boston MA

International Classification:

A61B 3/00

US Classification:

351246, 351201, 351202, 351209

Abstract:

Generally, the present invention relates to medical devices and a method of vision screening, and more particularly to a pediatric vision screening system and method thereof that identifies a risk factor for amblyopia or diagnoses amblyopia by measurement of microstrabismus. An embodiment of the invention is directed to a method of patient screening for risk factors for amblyopia which includes the steps of illuminating the eye with polarized light, scanning the polarized light about the eye, capturing the retro-reflected light emanating back from the eye, analyzing the retro-reflected light to determine ocular misalignment; and calculating a metric to determine if the patient passes or fails the screening test thereby providing an indication that the patient may have a risk of amblyopia based on either strabismus or anisometropia. The method is effective at detecting amblyopia related to focusing problems without the measuring the focus of the eye directly.

International Classification:

A61B 50478

US Classification:

600383

Abstract:

A headset and system for taking EEG measurements on the head of a test subject. The headset has a plurality of electrode sensors in predetermined anatomical positions on the head of a subject to take EEG measurements, for example of the subject's response to certain stimuli. The electrode sensors are formed of dry conductive foam rubber pads attached to conductor elements. An individual shielded cable is attached to each sensor to carry the detected signal to a signal processor. The sensors may be formed of a carbon impregnated foam rubber pad that offers high conductivity. The sensors do not require wetting agent, and thus can be used in a very time efficient manner, and can be easily replaced for sanitary considerations.

A61B 504

US Classification:

600544

Abstract:

A system to integrate and synchronize a plurality of signals for recording on a destination video recording device and/or for display on a monitor. The plurality of signals represent the response of a respective of a plurality of test subjects to certain stimuli. A plurality of test subjects view an audio-visual display from an audio-video source, such as a video cassette recorder, while respective EEG responses to the audio-video display are measured. The respective EEG responses are sent to respective processors and converted to graphical representations of the EEG signals. The graphical representations of the EEG signals and a signal from the source audio-video device are sent to respective destination VCRs and/or a respective destination audio-video recording device that records the data from both sources. The respective destination audio-video recording devices can send respective composite signals to a respective destination VCR and/or a respective destination monitor to record and/or display the synchronized signals from the source audio-video recording device and the graphical representation of the EEG signals simultaneously. The respective destination VCRs and respective destination monitors can also record and/or display output and control data such as the time and date of the test.
