摘要:
A firestopping apparatus including a housing having a wall surface extending between opposed front and rear panels with an inner chamber defined therein. The front panel defines a front opening therethrough and the rear panel defines a rear opening therethrough. The housing includes first and second housing members which are moveable relative to one another between an assembled condition wherein the first and second housing members are interconnected and the wall surface is substantially continuous about the internal chamber, and an open condition wherein at least a portion of the first and second housing members are spaced from one another such that at least a portion of the wall surface is non-contiguous to define an opening into the internal chamber. An intumescent material is positioned within the internal chamber.

摘要:
A device for providing active, closed-loop humidity control to the environment surrounding and within a hollow-bodied wood instrument. The device includes at least one humidity sensor, and preferably two, one for monitoring the environment's humidity, and one for monitoring the device's response. With data from these humidity sensors, a microcontroller determines whether the system should take action to increase the humidity of this environment by controlling a vapor-generating device. Water is supplied to this device by a water reservoir.
摘要:
An electrical connection device for electrically connecting an electronic component of the type having a plurality of electrical connection points. The electrical connection device includes an electrical cable extending between first and second ends with at least one of the ends including an interface plug with a first set of internal contacts in electrical communication with the electrical cable. The device also includes at least one connector adapter including a first end configured for connection to the interface plug and a second end defining an electrical connector. The at least one connector adapter includes a second set of internal contacts configured to conductively engage the first set of internal contacts such that the electrical connector is in electrical communication with the electrical cable.
