Abstract: Herein described may be an embodiment of a surround sound headphone device for the production of surround sound which may comprise a first and second headphone assembly which may have acoustic chamber surrounds. The acoustic chamber surrounds may envelope a first and second acoustic chamber assembly. The first and second acoustic chamber assembly may have an acoustic chamber dividing partition, a one or more than one high frequency external port, a one or more than one low frequency external port, a one or more than one low frequency high frequency port, a one or more than one high frequency high frequency port, a one or more than one high frequency auditory source and, a one or more than one low frequency auditory source.

Abstract: The present disclosure provides a device for holding portable electronics. The device may include a base, a plurality of legs rotatably connected to the base, and a platform rotatably connected to the base via at least one first hinge. The platform may be configured to receive an electronic device and to pivot about the at least one first hinge between a level position and an inclined position. The device of the present disclosure may further include a retractable grip connected to the platform and configured to move between a retracted position and an extended position outside of the platform. In the extended position, at least one contact of the retractable grip may be configured to provide a bias force to an upper surface of the electronic device, such that at least a portion of the electronic device is disposed between the platform and the at least one contact.

Abstract: Fluid flow cartridges, systems and methods for qualitative or quantitative analysis of a sample material are disclosed. Cartridges of the invention are constructed for fluid flow into, out of and internally throughout the cartridges. The cartridges can be used with an analytical instrument configured to interface with the instrument and present the sample or a reagent fluid at a location and in a form appropriate for analysis of the sample by the instrument. The invention is particularly advantageous for use in analytical systems in many fields but may also be used for non-analytical purposes.
