Abstract: An alarm system and method for use with a breathing apparatus that provides a source of breathable air to a user/diver. A tactile signal is generated in response to a signal representing at least one parameter corresponding to the breathing apparatus status, and the tactile signal can be both felt and heard by the user. The tactile signal may be generated in combination with a visual and/or an additional audible alarm. The tactile signal may be a vibration. The alarm may be worn on the face, either on the mask or on the mouthpiece. The vibrator serves two functions, one as a tactile alarm that the diver can feel during operation, and a second as an auditory alarm through bone-conduction of sound. The tactile alarm indicates to the user/diver that his particular unit is the one transmitting an alarm signal, and cannot be mistaken for any other device.
Abstract: An apparatus is disclosed which includes a drilling device and a tube. The drilling device typically has a first end, at which a point is located and a second end which is connected to a first end of the tube. The apparatus also includes an insertion bar having a first end inserted into the tube and a second end at which a latching device is located. The latching device can set a location of the insertion bar with respect to the tube so that a height is set. The apparatus may also include a first pole receiver connected at the second end of the insertion bar. The apparatus may include a handle which can be inserted into the insertion bar for rotating the insertion bar, tube, and drilling device to drill the drilling device into the ground.
