    Abstract: Feedback cancellation apparatus uses a cascade of two filters along with a short bulk delay. The first filter is adapted when the hearing aid is turned on in the ear. This filter adapts quickly using a white noise probe signal, and then the filter coefficients are frozen. The first filter models parts of the hearing-aid feedback path that are essentially constant over the course of the day. The second filter adapts while the hearing aid is in use and does not use a separate probe signal. This filter provides a rapid correction to the feedback path model when the hearing aid goes unstable, and more slowly tracks perturbations in the feedback path that occur in daily use. The delay shifts the filter response to make the most effective use of the limited number of filter coefficients.

    Abstract: A dual completion for gas wells includes a dual base with a primary hanger incorporated in the base. Primary and secondary coiled tubing strings extend through the base at a downwardly converging angle of 2.degree. or less. The dual base is mounted on an annular blowout preventer. At the top of the annular blowout preventer is a tubing centralizer that aligns the two tubing strings parallel to one another. The blowout preventer has two side ports below the bladder allowing the operator to produce gas from the annulus, to flare gas to atmosphere or to pump in kill fluid in the event of an emergency. The alignment of the tubing strings allows production recorders to be run in either string.

    Abstract: An in-flight contact charging system includes a charging contact, a power receiver, and a recharging controller connected to the charging contact. The charging contact is mounted on a support. The power receiver is mounted on an aerial vehicle containing an electrical load. The power receiver connects to the electrical load. The recharging controller can detect contact between the charging contact and the power receiver; transmit electricity to the charging contact; detect a spike in battery impedance; and discontinue transmission of electricity to the charging contact. The system enables a drone to rapidly recharge its battery while in flight by making brief contact between the charging contact and the power receiver. This system keeps the drone airborne, does not waste energy, and is comparatively cheap to build and maintain.
