    摘要： Described is a solid wax mitigation barrier for a hearing aid that is cleanable via a simple wiping motion, is not a cause of irritation within the ear canal, and is acoustically transparent. In one embodiment, a wax barrier function is provided by a tube cap for fitting over the acoustic port tube of a hearing aid receiver. The tube cap may be constructed of an elastomeric high tear strength material so as create a small flexible acoustic tube cap that prevents direct ingress of wax into the hearing aid receiver. The design of the cap may also include a bridge that spans an acoustic port inlet so as to block direct material ingress.

    摘要： A device to provide a quick and safe elimination of the supply of electricity to a building. The device attaches to the protective housing of the electric meter and permits the user to remain at a safe distance while further providing leverage to be applied to the meter to facilitate removal. If arcing of the electricity flowing through the meter occurs, the operator is safe from it harmful effects. It being recognized that during firefighting operations water is being applied in vast quantities and the dangers of arcing are significantly increased when water is present. The elimination of the supply of electricity to a building on fire is necessary to ensure the safety of the firefighters and other emergency personnel. The device is simple to apply and is applicable to all known types and sizes of meters. The extensive use of nonconductive materials, in the design of the device, ensure the safety of the user. Once the housing cover is opened or removed the device is secured to the protective cover of the meter by encircling the cover with a strap or band. A wedge shaped, or raised section, is provided to ensure a secure attachment to the protective cover, which generally tapers slightly inward toward the exposed end. Upward or downward pressure is then applied to the opposing end from attachment, the meter is pivoted, the connections disengage, the meter is removed from its housing, and the flow of electricity is terminated, while the operator remains at a safe distance.

    摘要翻译： 提供快速，安全地消除建筑物供电的装置。 该装置连接到电表的保护壳体，并允许用户保持安全距离，同时进一步提供施加到仪表的杠杆以便于移除。 如果发生通过电表流动的电弧，操作人员将无法避免有害影响。 人们认识到，在消防作业中，大量施用水，当存在水时，电弧的危险性会大大增加。 为了确保消防员和其他应急人员的安全，必须消除对建筑物的供电。 该设备易于应用，适用于所有已知类型和尺寸的仪表。 在设计设计中广泛使用非导电材料，确保用户的安全。 一旦壳体盖被打开或移开，装置通过用带或带环绕盖子固定到仪表的保护盖上。 提供楔形或凸起部分以确保与保护盖的牢固附接，该保护罩通常朝着暴露端稍微向内变细。 然后向上或向下的压力施加到相对端的附接，仪表枢转，连接脱离，仪表从其壳体移除，并且电流终止，同时操作者保持安全距离。

    摘要： An apparatus for changing a light bulb that is out of reach for a person even with the use of a six foot ladder includes a substantially hollow elongated member and an extendable member which is disposed within the substantially hollow elongated member. A locking member is engageable with the hollow member and the extendable member for adjusting the length of the apparatus. A replaceable vacuum cup having a predetermined shape is disposed on a first end of the extendable member for attachment to such light bulb. A vacuum pump is disposed adjacent a bottom portion of the hollow elongated member, such pump is engageable with the cup for creating a vacuum in the cup for securing such light bulb therein. A vacuum release assembly is disposed on the pump for releasing such vacuum.
