Abstract: An electronic cigarette (“e-Cig”) may include improved charging of the battery. A more accurate battery voltage can be detected for the connectors with the chargers that can provide for an optimized evaluation of the charging process. Various battery properties may be detected based on resistance measurements from within the e-Cig. The battery charging can be controlled and optimized based on a slow control of the current and voltage.

Abstract: An electronic cigarette comprises a battery portion which is operable to provide power to a heating element of the electronic cigarette, and a cartomizer coupled with the battery portion. The cartomizer comprises a liquid container which provides a liquid toward the heating element wherein the liquid is used for producing and flavoring a vapor of the electronic cigarette when the liquid is heated by the heating element, and a memory which is operable to record and store an amount of the liquid remaining in the liquid container.

Abstract: An electronic cigarette (“e-Cig”) may be wirelessly charged through an inductive charging system. A receiving coil in or on the e-Cig may be in proximity to a wireless charger that transmits electrical power to the battery of the e-Cig. Alignment of the receiving coil in the e-Cig with a charging base can wirelessly charge the battery of the e-Cig.

Abstract: An active acoustic noise reduction system which comprises a single input transducer and an output actuator that are physically located next to each other in the same location. In one embodiment, the input transducer and the output actuator are a hybrid represented by a single element. The active noise reduction system is located as close as possible to the noise source and functions to generate an antinoise cancellation sound wave with minimum delay and opposite phase with respect to the noise source. The noise reduction system also comprises a non linearity correction circuit, a delayed cancellation circuit and variable gain amplifier. The system provides user control of the quiet zones generated by the system by varying the gain of the variable gain amplifier. The system provides a user with the ability In one embodiment, an echo canceler is utilized to remove echoes fed back from the output actuator.

Abstract: Methods for arrangement of studs or dents over the road surface in a way that when a vehicle passes on the road, a desired sound that is dependent on the driving speed and the arrangement and properties of the studs or dents is generated into the vehicle. The studs or dents are attached to the road and used to pass audio information such as warnings to the driver.

Abstract: A method and system for reducing noise of a cooking hood having a body containing a motor and a muffler mounted on an upper section of the body so as to be in fluid connection therewith. A motor active noise reduction unit produces motor reduction noise for reducing motor noise. Likewise, a muffler active noise reduction unit produces a muffler noise reduction signal for reducing muffler noise.

Abstract: A method and system for inhibiting noise produced by one or more sources of undesired sound from pickup by a speech recognition unit, where a respective transducer is located proximate each source of undesired sound for converting each source of undesired sound to a corresponding electrical signal, and a noise reduction system is coupled to each of the transducers for converting each electrical signal to an equivalent anti-phase electrical signal of equal amplitude. An output of the noise reduction or a signal corresponding thereto is fed to the speech recognition unit so each of the anti-phase electrical signals cancels or reduces a corresponding electrical signal produced by the speech recognition unit upon picking up the undesired sound from the respective source.
