An attachment device (10) for attaching accessories to a support comprising a connector (14) for connecting to a device to be supported, and a strap (11), the strap (11) having a support region (12) mounting the connector (14), and first and second flexible engagement portions (16, 18); the first engagement portion 16 including a plurality of spaced deformable fins (20) extending from one side thereof and a plurality of through apertures (24) spaced along the length of the first engagement portion (16), the second engagement portion (18) including a plurality of spaced deformable fins (22) extending from one side thereof, and at least one upstand (26, 28) extending from the other side thereof adapted to enter and engage with at least one of the through apertures (24) of the first engagement portion (16).

A chair for particular use in clinical or hospital environments has a frame to which a support material is secured. The support material may form a chair back and/or a seat for the chair to provide support to the chair occupant. The support material may be made from a textile that includes copper containing particles such as copper iodide or copper oxide within the textile fibers.

Method and apparatus for improving sound quality in audio cables, including a plurality of equally spaced conductive discs separated by a gap and configured in a generally linear array, each of the discs having an annular shape with planar sides, an outer diameter, a center hole having a diameter, and a thickness. The disc array is placed around an audio signal cable such that the planar sides of the discs are oriented parallel to one another and perpendicular to signal cable axis. The spacing between discs is approximately four to ten times the thickness of said discs, and the disc diameter is between 2 and 4 times the diameter of the center hole.

The present application discloses a body support device for surgery with a dynamic support for the torso. This device stimulates the adoption of a more natural posture and provides the dissipation of the load placed on the bone and muscle structures in the spinal column through the combination of the torso support (1) to the posterior support (13). The posterior support (13) consists of the systematization of the human vertebral column, comprising a set of segments (13) chained and aligned by the passage of an elastic medium (14) therein, controlled by the user's action. Thus, this technology allows for minimizing surgeon's physical fatigue resulting from a prolonged posture in surgery.

A dental chair cover kit is provided. The kit includes a dental chair cover having a cover body configured to cover a portion of a back rest of a dental chair, a headrest pocket configured to receive a headrest of the dental chair, an extendable neck member interconnecting the cover body to the headrest pocket, and a bib removably affixed to the cover body. The pocket includes an interior volume sized to receive the headrest of the dental chair and an opening for providing access to the interior volume. The extendable neck member includes an accordion fold biased to a first collapsed position and extendable to a second extended position for enabling extension of the cover body relative to the headrest pocket. The bib includes a strap for removably securing the bib to a user and a slot configured to removably receive and retain an item on the bib.
