Abstract: A projection screen includes a substrate having at least a first surface, a reflective layer having a first surface and an opposing second surface, and diffusion layer having a first surface defined by a matte finish and an opposing second surface. The second surface of the reflective layer is attached (e.g., via an adhesive) to the first surface of the substrate and the second surface of the diffusion layer is attached (e.g., via an optically transparent adhesive) to the first surface of the reflective layer. The projection screen is preferably flexible and wound around a conventional roller to form a projection screen system. Alternatively, the projection screen may be attached to a rigid substrate. The second surface of the diffusion layer has a preferably smooth finish, but may include desired irregularities to achieve a desired screen directivity performance.

Abstract: A shelter to enclose articles of personal property such as motorcycles, bicycles, lawn and garden equipment, etc. comprising a base frame mounted coextensively in horizontal fashion to the ground, a plurality of u-shaped rib members covered by a suitable covering material which articulate around a novel hinge mechanism and which are essentially equally spaced in spanning relation over the base when in the first, covering, position and which are collapsed upon themselves in stacked relation when in the second, opened, position. A motor and gear assembly may be employed to permit automated operation of the device, or the device may be manually operated.

Abstract: A shutter system for covering a wall opening includes a mounting assembly and a retractable/deployable barrier assembly. The mounting assembly includes at least one pair of guide tracks that are mountable on opposing sides of the opening. Each guide track includes inner surfaces that define a guide channel. Two of the inner surfaces oppose one another and at least one of such surfaces includes a protruding member that extends into the guide channel and angles away from an open end thereof. The barrier assembly includes a series of interlocking slats, some or all of which define angled recesses constructed to accommodate unobstructed passage of the slats in the guide channel during deployment and retraction. The recesses in the slats are further constructed to enable the slats to engage the protruding members of the guide tracks in the event that the slats are deflected due to exertion of a displacement force.

Abstract: A storage case or receptacle used to secure CDs and DVDs used in rental or purchase applications. The case is comprised of a housing having a lid and a base between which is removably positionable a CD, DVD or the like. A releasable locking mechanism retains the lid and base in position in surrounding relationship about the CD or DVD. The locking mechanism may be of any type, such as some of the various security tag locks commonly used in the electronic article surveillance (“EAS”) industry.

Abstract: A method for producing a diamond includes forming a table lying in a table plane; forming crown facets that are oriented at an angle of between 26° and 35° relative to the table plane; forming upper pavilion (UP) facets below the crown facets at an angle of between 45° and 80° relative to a girdle plane lying between bottoms of the crown facets and tops of the UP facets; and forming a set of lower pavilion (LP) facets between bottoms of the UP facets and the culet at an angle of between 38° and 44° relative to the girdle plane. The UP and LP facets form a rib line positioned between one-fifth and four-fifths the distance between the girdle plane and the culet, such that the UP facets extend between 20% and 80% of the distance between the girdle plane and the culet.

Abstract: A sailboat sail includes a sheet of material that contains stretchable webs that assume a planar orientation when placed against a planar surface, but which can stretch into a sail or airfoil orientation when mounted to a sailboat and exposed to wind loading. The sheet includes at least two webs of PVC vinyl laminated together between which is disposed a scrim of polyester yarn. The yarn is cross-hatched in a predetermined directional pattern. The sail has informational content, such as advertising, printed thereon or otherwise imparted thereto. A method for manufacturing such a sail includes providing a sheet of the aforementioned sail material, printing on one or both sides of the sheet information content to be displayed while the sail is mounted upon a sailboat, and cutting the sheet into the shape of a sail. The sheet may be cut before or after the information is imprinted thereon.

Abstract: A text-to-speech system utilizes a method for producing a speech rendition of text based on dividing some or all words of a sentence into component diphones. A phonetic dictionary is aligned so that each letter within each word has a single corresponding phoneme. The aligned dictionary is analyzed to determine the most common phoneme representation of the letter in the context of a string of letters before and after it. The results for each letter are stored in phoneme rule matrix. A diphone database is created using a way editor to cut 2,000 distinct diphones out of specially selected words. A computer algorithm selects a phoneme for each letter. Then, two phonemes are used to create a diphone. Words are then read aloud by concatenating sounds from the diphone database. In one embodiment, diphones are used only when a word is not one of a list of pre-recorded words.

Abstract: The present invention relates to new and unique designs that improve and enhance the section properties of load bearing structural members, which have particular, but not exclusive, application in connection with aluminum extrusions for use in screened pool, patio and porch enclosures. The invention utilizes one or more reinforcing inserts or slats which attach to a structural member such as a hollow extruded beam to increase the effective wall thickness of the beam in the area where the slat is applied.

Abstract: A method of producing and using a solution, and the solution itself, for extending the shelf life of fresh flowers, fruits and vegetables after they are harvested which includes the steps of extracting juice from the flowers, flowering plant parts, fruits or vegetables, filtering the juice, disintegrating the parts from which the juice is extracted, extracting an enzyme or enzymes from the parts using a solvent without the denaturing the enzymes, removing the parts and mixing the remaining ingredients with the extracted juice.

Abstract: A process for preparing a consumable beverage containing a natural dairy beverage additive in the form of agglomerated natural milk powder. The powder is combined with other ingredients, either prior to being placed in the vending machine or upon demand within the vending machine, for the subsequent creation of a consumable beverage which includes the natural dairy beverage additive.

Abstract: The present invention relates to an improved electrical power strip which will automatically energize and de-energize one or more devices which are plugged into the strip, upon receiving an electrical signal from the primary device, without the need for manual actuation of a switch on the electrical strip or an under monitor system by the user. This system senses the primary status of the power supply through a low voltage power tap connector which is plugged in any appropriate socket of the primary device (which may be a personal computer). The output signal triggers a synchronous transfer switch or relay which enables power to secondary devices (which may be a monitor, printer, scanner, sub woofer, modem, etc.), permitting them to be synchronously turned on or off depending on the computer system status (ON or OFF).

Abstract: The invention is a small, portable illumination device which is used to illuminate reading material or other material. The device contains a clip which a user can employ to attach the device to a book or other reading material. The clip holds the illuminating device in place relative to the material. The device uses either battery or alternating current as power and can be switched from one to the other by insertion or removal of a male plug of a 120V AC/DC adapter into or from a jack in the device. The device can be turned on or shut off when a user switches the ON-OFF switch. In addition, there is a countdown timer which the user can set to a desired number of minutes. Once the countdown timer starts, the device will illuminate the material for the number of minutes to which the user set the countdown timer. When the countdown timer reaches zero, the device shuts off automatically. A buzzer sounds when the countdown timer reaches two minutes.
