Abstract: The frame of a heavy duty ratchet supports a spool about an axis of rotation. A handle, pivotable about the axis of rotation, includes protrusions engageable with toothed wheels on opposed sides of the spool to urge incremental rotation of the spool upon repetitive pivotal movement of the handle. A pair of spring-loaded pawls engage the toothed wheels to limit the direction of rotation of the toothed wheels. A cam, formed as part of the handle, disengages the pair of pawls from the toothed wheels upon pivotal movement of the handle to a certain extent to permit rotation of the spool in either direction.

Abstract: The disclosure relates to several embodiments of a concealed speaker system, The concealed speaker system further has a speaker assembly mounted to the base frame and an active member which may be formed of PVC, expanded PVC, hardened fibrous materials, foam core, or equivalents that has an outer surface which in some embodiments is substantially coplanar with the surrounding wall section, and in other embodiments extends slightly outward therefrom. The base frame, speaker assembly, and the active member cooperate to form an acoustic chamber that is positioned behind the inner surface of the active member. Acoustic energy is transferred from the speaker assembly to the active member where the sound is produced therefrom to the room.

Abstract: A device-mounted infrared (IR) camera and a hybrid visible/IR light projector may be used to project visible animation sequences along with invisible (to the naked eye) tracking signals, (e.g. a near IR fiducial marker). A software (or firmware) platform (either on the handheld device or to which the device communicates) may track multiple, independent projected images in relation to one another using the tracking signals when projected in the near-IR spectrum. The resulting system allows a broad range of new interaction scenarios for multiple handheld projectors being used in any environment with adequate lighting conditions without requiring the environment to be instrumented in any way.

Abstract: An image processing apparatus includes a first image pick-up unit, a projecting unit that projects imaging light, an optical unit that transmits part of light entering from a first image pick-up direction and guides the part of the light to the first image pick-up unit while reflecting part of the imaging light projected from the projecting unit and outputting the reflected light in the first image pick-up direction, and reflects part of light entering from a second image pick-up direction and guides the part of the light to the first image pick-up unit while transmitting part of the imaging light projected from the projecting unit and outputting the part of the imaging light in the second image pick-up direction, and an attenuating unit that is movably placed between two positions.

Abstract: A dynamic aperture, positioned in the path of light, includes a pair of parallel blades, a connecting member, a driving member, and a motor. The projection device includes a light source configured for generating light. The connecting member is fixed to the projection device and rotatably interconnects a same side of the blades. The driving member rotatably interconnects the opposite side of the blades so that the blades, the connecting member, and the driving member constituting a variable quadrangular frame. The motor is coupled to the driving member and is configured for rotating the driving member. Rotation of the driving member and restriction of the projection device to the connection member alter dimensions of the variable quadrangular frame and accordingly adjust a gap between the blades through which the generated light passes.

Abstract: Systems and methods provide audio-visual distraction to a patient while the patient is undergoing a surgical or other such medical procedure. When used in the context of a surgical procedure, local anesthetics are used to eliminate the pain of the procedure, autonomic blockade (beta blockers and/or alpha-2 agonists) is used to control autonomic responses, and audio-visual distraction is provided to distract the patient. The system allows reduction in the need for pharmacologic sedation.

Abstract: A removable vehicle entertainment system is provided. The system includes a video display screen for displaying entertainment to an occupant of the vehicle. The system can be removed from the docking bracket in the vehicle, and attached to an external docking station such that the system can be used independently of the power supply and speakers of the vehicle. Further, the system can be used as a self-contained personal entertainment system. The system includes mechanical and/or electrical componentry that determines audio mute and video display configuration based on a power signal and a docked signal.

Abstract: A projector includes a lamp unit. This lamp unit includes a lamp which emits light, a shield member in which an opening portion is formed which allows light emitted by the lamp to radiate to the exterior, a cover glass fitted to the opening portion, and a retention member which retains the cover glass by squeezing it against the shield member. The retention member is provided with projecting flange portions which press against the four edges of the cover glass.

Abstract: A rear projector has a lower cabinet disposing an image generator and an upper cabinet for a screen body to be mounted, two woofer boxes being mounted on the front side of the lower cabinet and high-pitched sound speaker boxes being respectively mounted on the right and left lateral sides of the upper cabinet, so that, since the woofer box is disposed in the lower cabinet, vibration is not easily transferred to a screen body on the upper cabinet and a reflection mirror inside the upper cabinet, thus avoiding flicker of the image on the screen body even when great volume of sound is outputted by the woofer box.

Abstract: A method and system of projecting light on a planar surface to produce an image for tracing is disclosed. The system includes a projector that has a light source and a signal conditioner that is operably connected to the projector. A computer is operably connected to the signal conditioner. A scanner is connected to the projector. A test pattern from the computer is projected from the projector through the scanners to visually align an image to a sector on a work surface. A grid is operably aligned with the work surface. A geometric pattern from the computer is then projected by the projector on the planar work surface for tracing. The method comprises the steps of creating a pattern, tracing lines along the pattern on the planar work surface, cutting the pattern along the traced lines, discarding pieces of the planar surface outside the pattern, and placing edging along an outer edge of the pattern.

Abstract: Autostereoscopic images are produced by projecting a stereo pair of images onto a modified cube-corner retroreflective material. The cube-corner differs from that commonly available in that it has been altered to return the light to viewers eyes rather than directly back to the source of the projection.

Abstract: An improved audio-visual toy is provided by a housing assembly configured to simulate a portable television set. A magnetic deck assembly reads the signals on a magnetic tape element to produce an audio transmission that describes a story. Concurrently, the signals tell the user when to activate a pneumatic system that houses a clutch and ratchet system to advance a film element for producing a sequence of projected images that also describe the story.

Abstract: A motion picture projector having a housing or casing having one narrow side and one wide side, substantially perpendicular to each other. The film spools are arranged on the wide side. In a first projection position, the housing is arranged upright, resting on its narrow side, with the wide side approximately vertical. To enable projection to take place also when the projector is laid on a wide side, rather than standing upright, a first mirror is swung into position across the beam of projected light rays, and projects the rays upwardly to a second mirror arranged at an opening in the wide side of the housing. A control knob moves both mirrors simultaneously to effective projecting position, and also serves to adjust the exact inclination of the second mirror so as to vary the height of the projected image on the viewing screen at some distance from the projector.
