  • Patent number: 8463565
    Abstract: A flashlight includes a light powered by a battery, and a circuit having: a memory for storing a battery life information and voltage output information versus time for the battery to power the light, a controller operating a count down timer to accumulate an amount of time that the battery powers the light, a voltage measure circuit for monitoring the voltage output by the battery while the battery powers the light and supply the voltage output to the controller. The controller determines: a first remaining battery life by comparing the accumulated time to the battery life, a second remaining battery life by comparing the voltage output to the voltage output information, and the lesser of the first and second remaining battery lives. The flashlight includes a display for receiving a command from the controller to display the lesser of the first remaining battery life and the second remaining battery life.

  • Patent number: 7659674
    Abstract: Methods and apparatus involving at least two LEDs configured to generate at least two different spectra of radiation that are combined to produce white light. At least one parameter of the at least two different spectra of radiation generated by the at least two LEDs is controlled, based at least in part on at least one lighting control signal received by the apparatus over at least one wireless communication link, so as to control at least a color temperature of the white light.

  • Patent number: 7364488
    Abstract: Methods and apparatus for enhancing an inflatable device. In one example, a first component adapted to generate at least one of light and sound is coupled to a second component that is adapted to facilitate insertion into an inflatable device. The first component may be an LED-based light source configured to generate single or multi-colored light in an interior space of the inflatable device once inserted into the inflatable device. The second component may be particularly configured with one or more valves or seals to facilitate a transfer of a substance (e.g., an inflating substance) into the inflatable device once the first and second components are inserted into the inflatable device. The second component also may be configured to conveniently facilitate an effective seal between the second component and the inflatable device.

  • Patent number: 5313557
    Abstract: A pen recorder comprises a hollow pen body having a proximal end and a distal end a solid state audio recorder in its interior. A retractable pen mechanism is mounted on the distal end of the pen body, and a microphone transducer and speaker transducer are mounted at the proximal end. The speaker transducer is transversely mounted across an open proximal end of the pen body so that the interior of the pen body acts as a resonator improving the sound quality of the speaker.

  • Patent number: 4794803
    Abstract: An improved SCUBA diving gauge. A pictograph display is provided which has a shape which conveys the type of information being displayed. The pictograph has the shape of a SCUBA tank for a tank pressure display and the shape of a person for a display of nitrogen absorbed. Pressure transducers coupled to the SCUBA tank and the external water provided the pressure readings required to produce the respective displays. The differential signal from the transducer is supplied to a processor through an auto-zeroing circuit. The auto-zeroing circuit uses a capacitor initially coupled to an amplifier reference input and single ended output to store an offset voltage. During a measurement, the capacitor is disconnected from the amplifier output and has its other lead coupled to a full scale value of the differential input to produce an output signal which is a ratio.
