Title: Safety harness system for children with medical lines
Inventor: CAMPBELL MICHAEL C
IPC: A62B35/00
Filed: 1997-03-18
Abstract: A harness system to insure the safety of children or other patients or with I.V., enteral, and/or other long term hook-ups is easily and readily adjustable. This is complicated by routing of the medical lines with the adjustable straps, which is needed for growing patients, multiple patient use, and alternating medical equipment. The harness is high on the patient's chest, making it as out of the way as possible. The hardware used has rounded edges, and is with out protruding, parts to accommodate the patient and the medical lines. Hardware of the smallest size possible, and still being failsafe is used for the patient's comfort. The said medical lines are routed in such a way to prevent pulling, and kinking. This allows the patient maximum movement from the medical equipment. The loops of medical lines made by routing the lines along the tether strap, connecting the harness to the pumps, is held in place with a zipper sleeve.

Abstract: A container raising and conveying device, a two wheel hand cart, a carrier, a two wheel dolly used for moving recycle boxes, trash containers, storage containers, laundry hampers and many other containers. It has a unique approach using two hooks that hook under the overlap, the lip, the fold-over, the rim at the top of the containers and by pulling back on the handle, levers the container off the ground without having to lift anything. This is a similar approach as a pry bar for removing a nail, thus removing the burden of carrying a heavy container. This is where "Le Litter Buggy" takes the "HEAVY" out of the job.

Title: Micro-cellular capacitor for use in implantable medical devices
Inventor: MATTHEWS M DEAN
IPC: H01G2/14
Filed: 1997-05-02
Abstract: A capacitor optimized for use in an implantable medical device such as an implantable defibrillator is disclosed. In its simplest form, the capacitor comprises a thin planar dielectric sheet that has an array of cells open to one or both sides. Metallization is applied to the surface of the cells such that the walls of adjacent cells form a capacitor with the wall that separates the cells serving as the dielectric. The metallization pattern that forms the electrical connection to the cells may be patterned to limit the allowable current flow to each individual cell, thereby providing a fuse in the case of local dielectric failure.

Abstract: Tundishes and ladles used in processing molten metals and alloys frequently contain both as permanent and disposable linings. The disposable lining acts as a thermal and chemical barrier to protect the permanent lining. However, the presence of alkali in the disposable lining results in a tendency to bond to the permanent lining making removal of the disposable lining difficult. The present invention provides a disposable lining material comprising: a basic refractory aggregate comprising magnesia, magnesite, olivine, doloma, dolomite, calcia, or mixtures thereof; and at least one density reducing material comprising hollow ceramic microspheres in an amount sufficient to reduce the density of the composition.

Abstract: An integrated search processor (128) used in a modem (110) for a spread spectrum communications system buffers in a buffer (172) received signals samples and utilizes a time sliced transform processor (120) operating on successive offsets from the buffer (172). The search processor (128) autonomously steps through a search as configured by a microprocessor (136) specified search parameter set, which can include the group of antennas to search over, the starting offset and width of the search window to search over, and the number of Walsh symbols to accumulate results at each offset. The search processor (128) calculates the correlation energy at each offset, and presents a summary report of the best paths found in the search to use for demodulation element (122) reassignment. The search is done in a linar fashion independent of the probability that a signal being searched for was transmitted at any given time.

Title: Method and apparatus for providing speaker authentication by verbal information verification using forced decoding
Inventor: LEE CHIN-HUI
IPC: G10L17/00
Filed: 1998-05-29
Abstract: A method and apparatus for authenticating a proffered identity of a speaker in which the verbal information content of a speaker's utterance, rather than the vocal characteristics of the speaker, are used to identify or verify the identity of a speaker. Specifically, features of a speech utterance spoken by a speaker are compared with at least one sequence of speaker-independent speech models, where one of these sequences of speech models corresponds to speech reflecting information associated with an individual having said proffered identity. Then, a confidence level that the speech utterance in fact reflects the information associated with the individual having said proffered identity is determined based on said comparison. In accordance with one illustrative embodiment, the proffered identity is an identity claimed by the speaker, and the claimed identity is verified based upon the determined confidence level. In accordance with another illustrative embodiment, each of a plurality of proffered identities is checked in turn to identify the speaker as being a particular one of a corresponding plurality of individuals. The features of the speech utterance may comprise cepstral (i.e., frequency) domain data, and the speaker-independent speech models may comprise Hidden Markov Models of individual phonemes. Since speaker-independent models are employed, the need for each system user to perform an individual training session is eliminated.
