Abstract: The invention provides a two way mailer formed of a single blank of sheet material including first and second sections, and a perforated line for separably interconnecting the first and second sections. The first section includes bottom, top and side edges, and a first fold line spaced inwardly from and parallel with the bottom edge. The first fold line defines front and rear portions of the first section. The second section includes rear and return panels, each including bottom, top and side edges. The bottom edges of the rear and return panels coincidently define a second fold line parallel with the first perforated line and about which the return panel may be folded onto the rear panel.

Abstract: A system is disclosed for monitoring the position of a medical instrument with respect to a patient's body and for displaying at least one of a plurality of prerecorded images of said body responsive to the position of said medical instrument. In one embodiment the system includes a reference unit secured from movement with respect to the patient's body such that said reference unit is substantially immobile with respect to a target operation site.

Abstract: Antibodies against Ins(1,4,5)P.sub.3 were raised by immunizing rabbits with two types of IP.sub.3 -BSA conjugates which were synthesized by covalently coupling Ins(1,4,5)P.sub.3 to the carrier protein via alkyl linkages. The anti-Ins(1,4,5)P.sub.3 antibodies were detected by an ELISA where Ins(1,4,5)P.sub.3 was covalently attached to a microplate well surface. Both antiserum preparations showed specific binding with Ins(1,4,5)P.sub.3. The specificity of these antibodies was enhanced by affinity purification for the antiserum through Ins(1,4,5)P.sub.3 -agarose chromatography. The affinity-purified antibodies have IC.sub.50 values of 12 nM and 73OnM for Ins(1,4,5)P.sub.3 and Ins(1,3,4,5)P.sub.4, respectively. These antibodies showed many properties similar to those of biologically relevant receptors for Ins(1,4,5)P.sub.3.

Abstract: A hand held computer game including a housing, game controls located on an outer surface of the housing, a light source disposed within the housing and being operative to direct light along a light path, an at least partially transparent image surface disposed along the light path and a non-transparent reflective viewing surface having optical power, mounted on the housing and arranged to display an enlarged image of the transparent image surface to a user.

Abstract: Disclosed is an assembly seal for use in assembly comprising: packing formed in a predetermined shape from an elastic material; a core within the packing for providing substantial rigidity such that can maintain the desired shape of the packing; and a base for supporting the core, the base having substantial rigidity and being connected to the core portion in such a manner that the base can be easily separated from the core by a cutting operation. The assembly seal is used in an assembly method for assembling a plurality of parts into a set of assembled parts incorporating packing. The assembly method comprises the steps of: positioning the assembly seal so that the packing of the assembly seal is positioned at a specified position on one part of a set of assembled parts; separating the base of the assembly seal from the packing; removing the base so that only the packing of the assembly seal is left on said one part; and fitting the other parts of said set of assembled parts to said one part.

Abstract: The present invention relates to novel entangled-photon microscopy, spectroscopy and display systems. The systems include a source of light in the form of twin or multiple entangled-photon beams. The systems also include optical components that direct the twin or multiple entangled-photon beams towards a target material. The target material includes emission or indicator means responsive to an energy, which approximately equals the sum of the energies of the entangled photons. The systems may further include imaging means that is sensitive to the response of the target material. The present invention also relates to novel correlated-photon microscopy, spectroscopy and display systems. The present invention further relates to methods of correlated-photon microscopy in which a pump beam of photons is provided. A portion of the pump beam is split into a first beam and a second beam, the beams having corresponding correlated photons.

Abstract: A charge transfer device including a semiconductor substrate, a gate electrode provided in association with the substrate, the gate electrode having a corresponding channel region through which charge is propagated, the channel region having a predetermined potential; and means associated with the channel region for reducing charge trapping and recombination effects. In one aspect of the present invention, the reducing means includes a potential pocket defined within the channel region having a greater potential than the predetermined potential of said channel region. The potential pocket has a width dimension which is less than the corresponding width dimension of the channel region. The potential pocket is positioned in the center of the gate electrode, and is positioned so as to be aligned with a front edge of the gate electrode.

Abstract: A cartridge squeegee head for solder paste machines. A squeegee blade is fixed to a coupling block. The coupling block is characterized by a coupling slot formed therein. The coupling block pivots and puts the squeegee blade into a print stroke position. The squeegee blade is then driven across the stencil foil surface.

Abstract: A camera having an operating mechanism which comprises a body providing a film take-up chamber for containing an initially empty film cartridge, an exposure chamber having an open rear side, and a film supply chamber for containing a roll of film pre-exposed with border images on respective frames to define respective unexposed areas for subsequent photographic exposure. The operating mechanism includes a shutter mechanism, a film-advancing member for advancing the film frame-by-frame from the film supply chamber to the film take-up chamber across the exposure chamber rear side, and a trigger mechanism for operating the shutter mechanism in response to film advancement by the film-advancing member. A movable cover is used between the exposure chamber rear side and the film, which has a see-through portion to reveal the unexposed area for photographic exposure while protecting the border image of each successive frame.

Abstract: A spatial light modulator formed of a moveable electrode which is disposed opposite a fixed electrode and is biased to roll in a preferred direction upon application of an electric field across the electrodes to produce a light valve or light shutter. In one embodiment, the moveable electrode is restrained at one end and coils about the fixed end in a preferential roll direction. The bias is achieved by inducing anisotropic stress or anisotropic stiffness.

Abstract: Method and system for enhancing the function of sensory cells are disclosed. The method comprises locating a sensory cell area associated with the sensory cell whose function is to be enhanced and inputting a bias signal to the sensory cell area. The apparatus comprises a signal processor for producing a bias signal and an input device for inputting the bias signal to a sensory cell area associated with a sensory cell whose function is to be enhanced. Inputting the bias signal to a sensory cell area effectively lowers the threshold of sensory cells with which the sensory cell area is associated.

Abstract: The present invention provides a resonant cavity including a planar two-dimensional periodic dielectric structure which exhibits a photonic band gap and a defect in the periodic dielectric structure which results in an electromagnetic mode within the photonic band gap. The photonic band gap effects an in-plane spacial confinement of electromagnetic radiation generated within the structure. The electromagnetic radiation is vertically confined by total internal reflection.

Abstract: A method and system for deconvolution derived from the CLEAN technique. The nonlinear CLEAN method, combined with a priori knowledge of the point spread function allows for extraction and subsequent transmission of the non-redundant information. The point spread function is then treated as the redundancy function. Thus, the data set may be regarded as a convolution of the non-redundant information with the redundancy function. Since the non-redundant data is a small subset of the overall data set, images and/or other data may be transmitted over narrowband channels using the system of this invention. Effective data compression may be further enhanced by using the system of this invention prior to additional compression or encoding techniques based upon the digital data and digital compression techniques.
