The handheld demi-face shield device includes a demi-shield comprising an outer edge, a handle end, a left edge, a right edge, a block end, a bottom portion, and a top portion; a nose bridge, a dowel adapter; and a dowel handle. The nose bridge is removably affixed to demi-shield and the dowel adapter includes a slideable clip, a receiving portion, a face, plurality of dowel holes, a dowel cuff; there is also a dowel handle.

Abstract: In a particular implementation, an apparatus to control clamping devices includes a detection circuitry, a clamping device, inverter circuitry, and first and second control circuitry. In response to a first voltage corresponding to a gate terminal of the clamping device, the first control circuitry is configured to generate a second voltage to set the first voltage below a first voltage threshold. Also, in response to the second voltage, the second control circuitry is configured to generate a third voltage to set a voltage of the detection circuitry below a second voltage threshold.

Abstract: An eyeglass storage system is provided for use in combination with electronic devices, such as smart phones. The storage systems disclosed herein include a casing having a storage cavity within the casing that houses compact reading glasses. The casing may be a unit that attaches to electronic devices, or may be a combination casing that houses the electronic device along with the reading glasses.

Abstract: An article of eyewear includes an elongated bi-stable spring, two lenses disposed along a side edge of the elongated bi-stable spring in a spaced apart relationship with each other along the side edge, a flexible covering encasing the elongated bi-stable spring and the two lenses, and an arcuate shape defined between the two lenses.

Abstract: A vision assist device without side temples comprises a frame for holding a first vision assisting lens with a carabiner clip that extends from the frame for use as a handle. The carabiner clip has at least 3 sides, at least one of said sides including a bar with spring biasing to define a closed clip position. The carabiner clipped device can be used as reading glasses, a magnifying glass, lorgnette and/or binoculars. Optionally, the carabiner includes a switch-activated light. One preferred embodiment uses overlapping lenses to provide twice the vision correction when folded closed.

Abstract: An apparatus to implement a deflate process in a compression engine. An embodiment of the apparatus includes a hash table, a dictionary, comparison logic, and encoding logic. The hash table is configured to hash a plurality of characters of an input data stream to provide a hash address. The dictionary is configured to provide a plurality of distance values in parallel based on the hash address. The distance values are stored in the dictionary. The comparison logic is configured to identify a corresponding length for each matching distance value from the plurality of distance values. The encoding logic is configured to encode the longest length and the matching distance value as a portion of a LZ77 code stream.

Abstract: Eyeglasses having an integral case. The eyeglasses may swivel or slide out from a protective case. An attachment mechanism, such as a clip, may be integrated with the case. A file or other personal care item may also be integrated with the case or frame. In another embodiment, the earpieces of the eyeglasses can be folded to cover at least a majority of the surface area of the lenses.

Abstract: An eyeglass apparatus is provided including a pair of lenses and a housing therefor in which the lenses are disposed in a stowed position and are able to be shifted to a use position while still connected to the housing. The lenses are operably connected to a pivot mount, so that they pivot into and out from the housing to provide for space conservation in the housing. A detent is provided between the lenses and housing which releasably maintains the lenses in their stowed position and is operable via an actuator to allow the lenses to shift to their use position where the housing preferably is between the lensee to be used as a handle. In this form, the housing includes opposite side openings, and there is a biasing mechanism that urges the lens assemblies out through the side openings. The viewing lenses are kept attached to the housing whether in the stowed or use position thereof so as to prevent their separation from each other, and the potential for loss that this creates.

Abstract: Flyglasses having two lenses, at least one of which is faceted and both of which are held in a mount that is preferably flat. The mount can be in the form of a so-called lorgnette having a handle made in the form of a small board which is especially suited for application of decorative patterns or advertizing or it can be in the form of conventional eyeglass frames or goggles.

Abstract: An emergency lorgnette making it possible for a user having defective eyesight to see reasonably well regardless of the nature of the defect. The lorgnette is molded of transparent synthetic plastic material to define a strip having formed at one end thereof a handle and along its length in alignment with the upper edge of the strip, first and second pairs of lenses in staggered relation, whereby the left eye lenses of the two pairs which are adjacent each other are spaced from the right eye lenses of the two pairs which are adjacent each other. Indented in the lower edge of the strip are first and second notches, each of which is adapted to receive the bridge of the user's nose when the lorgnette is held by its handle adjacent the eyes of the user. The first notch is placed midway between the left and right eye lenses of the first pair, the second notch being placed midway between the left and right eye lenses of the second pair.

Abstract: A swizzle stick for stirring mixed drinks, the stick being convertible to a lensless ophthalmic device, making it possible for a typical individual having defective sight to see clearly regardless of the nature of the defect. The swizzle stick includes a strip section having a profile defining a pair of eyepieces joined to a nose piece and a handle extending from one of the eye pieces. Extending from the other eyepiece is a swizzle shank, the junction therebelow being scored so that the shank may be broken off to convert the stick to an ophthalmic device. Each eyepiece has a pattern of pin holes therein adapted to project a clear image of the object viewed by the related eye of the user of the device.

Abstract: An audio frequency signal identification apparatus of the present invention has a correlator for obtaining the full band power component and autocorrelation coefficients of a digital audio frequency signal to be identified for each analysis time, a plurality of band pass filters for dividing and filtering the audio frequency signal into a plurality of bands, a plurality of integrators for full wave rectifying and integrating the outputs from the plurality of band pass filters for each analysis time so as to obtain individual power components for the respective bands, a first identification parameter calculator for calculating a maximum power component, a minimum power component, a frequency band yielding the maximum power component, a bandwidth, and a difference between the individual band power components in the respective analysis times, from the individual band power components as the outputs from the plurality of integrators, a second identification parameter calculator for calculating a difference betwee

Abstract: A lorgnette eyeglass frame has a lens-bearing frame and a handle of box-shaped conformation. The frame is slideably guided within the handle which constitutes the case for same.
