Abstract: A programmable fountain controller for varying the flow rate of an AC PMSM fountain pump in a pre-determined manner so as to generate dynamically changing flow patterns. A micro-controller is provided to vary the pulse width and frequency timing over time for generating signals to an output switching circuit that drives the pump. A mode switch provides user-settable modes of operation selected from a group comprising a programmed flow control mode, a manual flow setting mode, an audio input mode and an external data input/output mode.

Abstract: Removably attachable wrist band devices for use in helping an addicted cigarette smoker permanently quit smoking. The devices comprise an acupressure stimulator section, a wrist attachment section, and an elastic section with controlled elasticity. The wrist band is placed on a user's wrist such that the acupressure stimulator is positioned proximal to the L-7 acupuncture point and the elastic section of the wrist band is positioned on top of the user's wrist. The elastic section of the wrist band is designed to limit the maximal energy that the user can transfer to a unit area of skin when the band is snapped against the wrist. This is so that snapping the wrist band will not be perceived as aversive to the user. The disclosed wrist band devices have the dual functions of providing a non-aversive behavioral modification function together with providing stimulation of the L-7 acupuncture point, which has therapeutic value in treatment of smoking addiction.

Abstract: A removeably attachable wrist band device for use in helping an addicted cigarette smoker permanently quit smoking. The device comprises an elastic section, a hook fastener section, a loop fastener section, and an acupressure stimulator. The device is placed on a user's wrist such that the acupressure stimulator is positioned proximal to the L-7 acupuncture point and the elastic section of the wrist band is positioned on top of the user's wrist. The elastic section of the wrist band is designed to limit the maximal energy that the user can transfer to a unit area of skin when the band is snapped against the wrist. This is so that snapping the wrist band will not be perceived as aversive to the user. The disclosed wrist band has the dual functions of providing a non-aversive behavioral modification device together with providing continuous and differential stimulation of the L-7 acupuncture point, which has therapeutic value in treatment of smoking addiction.

Abstract: Improved optical holographic apparatuses are disclosed for making white light viewable rainbow holograms in one step utilizing concave mirror optics. On-axis and off-axis configurations are presented for holography of real objects and for reduced image holography of a real image projection from a laser transmission hologram. An optical apparatus and curved recording devices are devised to reduce and/or eliminate certain aberrations introduced by the concave mirror. To yield a wide holographic field of view at low cost, small diameter mirrors are employed in two alternative devices for replacing a single concave mirror in the various embodiments. Two methods are then presented to obtain reduced image size one-step rainbow holograms from a full size object or holographic image.

Abstract: An exposure station and a film transport comprise apparatus for recording a series of strip holograms on a continuous length of non-perforated film. The apparatus includes a vacuum-platen for keeping the film stable during holographic recording and a film stepping mechanism for advancing the film in equal steps between successive exposures. The film stepping mechanism is operationally coupled to the vacuum-platen and includes a drive arm that grips the film during each advance and releases the film without backlash between successive film advances. The film stepping mechanism includes a single-acting vacuum cylinder for moving the drive arm. The apparatus does not introduce strain in the film during the transport process which could result in non-uniform demodulation of the successive strip holograms. The stepping increment (holographic strip width) is adjustable with accurate increments as small as 0.005" being obtainable.
