Abstract: A microphone can include a cover having a series of slits and a nest. The nest can be configured to receive a first diaphragm, a second diaphragm, and a PCB in a stacked arrangement, such that the PCB is positioned between the first diaphragm and the second diaphragm. Also, the first diaphragm can define a first plane, the second diaphragm can define a second plane, and the PCB can define a third plane and the first plane, the second plane, and the third plane can extend parallel to one another. The cover can also include slits having a first length and a second length, and the first length can be greater than the second length. The slits can extend both radially and axially.

Abstract: A communications headset in which a microphone at the end of a support boom can be adjustably secured in a position selected by the wearer and can accommodate a variety of wearers. The headset may include a boom arm clip configured to receive a boom arm retaining a microphone. The boom arm clip can include an opening, and the opening may include a pair of grooves, the pair of grooves together can define a channel sized to fit and retain the boom arm therein. The headset may also include an adjusting knob, which can secure the boom arm clip in order to adjustably fix the boom arm in a number of positions on the headset to accommodate for different sized users.

Abstract: A shock mount for a microphone comprises a first frame member having an upper ring-shaped frame member and a lower ring-shaped frame member. The lower frame member has a microphone mount for receiving a microphone. The shock mount also has a second frame member comprising a ring. The first frame member is suspended from the second member by wire rope or other substantially non-elastic flexible material, and the wire rope is configured to help reduce the amount of vibration encountered by the first frame member. A method comprises providing a first frame member and a second frame member and suspending the first frame member from the second frame member by wire rope or other substantially non-elastic flexible material and mounting a microphone on the first frame member to help reduce the amount of vibration encountered by the first frame member and the microphone.

Abstract: A Czochralski single crystal pulling apparatus having a one or more flow nozzles used to reduce or eliminate unwanted orbital motion during crystal growth. A portion of the purge gas supplied to the crystal puller is diverted to the flow nozzles, which direct purge gas flow on the growing crystal in a direction that counteracts the orbital force. Mass flow controllers and/or valves are actuated by a controller such that flow is only directed by any flow nozzle when the crystal is in a perigree interval relative to that nozzle, with the proper amount of purge gas directed such that orbit can be significantly reduced or eliminated.

Abstract: A method for universally distributing a therapeutic agent, in an encapsulated form, to the brain of a subject using intrathecal administration, excluding the lumbar region, is described. Methods for treating stroke and/or Traumatic Brain Injury (TBI) are also described. The methods involve intrathecal administration into the cerebrospinal fluid of a subject, of a therapeutic agent in an encapsulated form. Pharmaceutical compositions intended for the amelioration of stroke and/or Traumatic Brain Injury (TBI) are also described. The pharmaceutical compositions comprise a therapeutic agent encapsulated in a pharmaceutically acceptable polymer, suitable for injection into the cerebrospinal fluid of a subject suffering from stroke and/or Traumatic Brain Injury (TBI).
