This invention is a removable flashlight insert for fitting into an oil-type cigarette lighter outer case. The flashlight insert contains an LED lamp module with a movable switch element and a battery module contained within a top chamber and a bottom chamber respectively of an outside metal shell. The outside metal shell provides a direct conduction path between a battery terminal in the bottom chamber and the movable switch element in the top chamber. The flashlight insert may contain two different LEDs, where either of the two LEDs may be user selected by a separate switch. A rechargeable flashlight insert is also shown having an electronic circuit contained inside the outer metal shell. Lamp and battery modules are also provided in a kit to transform an oil-type cigarette lighter insert into a flashlight insert.

This invention is a night light assembly containing a multiple LED light source and an electronic controller whereby the electronic controller causes the multiple LED light source to continually change its light output from a high intensity photopic light output to a low intensity scotopic light output in response to a transition from light to dark of an ambient light, matching a human eye response to a sudden decrease in ambient light.

Momentary night light assembly

This invention relates to assemblies used as night lights and contains certain embodiments that improve, add features, and/or lower the cost of the type of momentary night light defined by U.S. Pat. No. 7,253,570. The words 'momentary night light assembly' as used in this invention means a light that remains lit for only a short fixed period of time following a transition from light to dark of the local ambient light. It then turns itself off after a short time period until another light to dark transition occurs. The words 'night light' as used herein means a light that remains on while the local ambient light is dark following a light to dark transition.

A secondary light assembly emits light into an area lit by a primary light source. The secondary light assembly includes a light sensor for sensing light emitted from the primary light source. A secondary light source is operatively connected to the light sensor. A controller is electrically connected to the light sensor and the secondary light source. The controller calculates a rate of change of light emission from the primary light source such that the controller turns the secondary light source on when the rate of change of light emission from the primary light source is above a predetermined rate threshold.

An eyes up instrument having a transparent display is disclosed which is mountable on or above the dashboard of a vehicle to allow the instrument to be read by a vehicle operator without lowering his eyes to the vehicle instrument panel. The display of the instrument is transparent and therefore does not interfere substantially with the view of the operator. The compact design of the instrument and use of a miniature crossed coil gauge supported in the display itself allow it to be mounted unobtrusively on a dashboard even in applications where transparency is not required.

A miniature crossed coil gauge is provided having an oriented rare earth magnet fixedly mounted on a rotary shaft for supplying a magnetic flux directed transverse to the shaft axis. The gauge housing provided by an upper and lower bobbin surrounds the magnet and supports the rotary shaft. A first and second coil are wound about the gauge housing in a crossed coil orientation encircling the magnet. A flux ring is disposed around the first and second coils axially aligned with respect to the magnet. The magnet has sufficient strength and the flux ring is mounted in sufficiently close proximity to the first and second coils to redistribute the flux supplied by the magnet so that the magnetic flux measured at the surface of the coils is substantially increased relative to the magnetic flux density measured with the flux ring removed. This gauge construction facilitates the fabrication of gauges so small that they can be directly mounted on printed circuit boards using conventional electronic component mounting equipment.

A miniature telltale module which combines a plurality of telltale functions into one unit and provides reduced cost per function. The module uses a miniature rotary actuator or driver, an image disc having a series of interconnected images or icons and a single light source. The actuator or driver allows a wide tolerances at the inputs while still precisely selecting the image positions. The module includes a light absorbing shield disposed about a light source and having a light opening positioned and sized to provide illumination of the icon, containment of light not directed through the light opening, and control of the angle of light emitted from the opening.

An compass having an electronic magnetic field sensor and an analog directional display is disclosed wherein a signal from the field sensor proportional to one component of the earth's magnetic field is alternated in polarity and integrated to produce a triangular waveform the frequency of which is proportional to the strength of that field component and wherein a triangular waveform having a frequency proportional to the second component of the earth's magnetic field is produced in the same manner. These values are used by a microcontroller to control an air-core gauge such that a disk with reference markings attached to the gauge remains positioned with one of the reference markings facing either magnetic or true north. A resistor ladder network is also connected in parallel to the inputs of the integrators and controlled by the microprocessor through a shift register in order keep the integrators out of saturation.

A back lighting device is formed as an assembly of a frame, light waveguide, lamp and terminal assembly and a diffuser sheet. In one embodiment, the lamp and terminal assembly is received in a pocket through a rear opening in the frame and includes terminals having leg portions that are seated on seat portions in the pocket that optimally align a lamp member of the lamp and terminal assembly with an edge of the waveguide to provide optimum light transmission into the waveguide. The diffuser sheet covers the rear of the waveguide and extends across the rear opening of the pocket to limit the escape of light from the pocket and the waveguide to the rear of the back lighting device. The diffuser and frame are preferably molded of a white glass filled material that provides good diffusion of light reflected therefrom and reflects a maximum amount of diffused light back into the waveguide for transmission through a front surface for back lighting of a liquid crystal display or other light receiving member.

A back lighting device includes a light waveguide having generally planar upper and lower surfaces, a light module having a lamp member encapsulated between the upper and lower surfaces, a specular reflective material applied about the waveguide lower surface, and a light extracting material applied about the waveguide upper surface. The waveguide can be mounted in a user specific frame to allow high volume usage of a common waveguide element.
