FIG. 2A illustrates an embodiment of the communications headset 100 wherein the first arm 160 is in an engaged position and the second arm 180 is in an inactive position. When the first arm 160 is in the engaged position, the microphone 162 of the first arm 160 may be located proximate the mouth of the user. When the second arm 180 is in the inactive position, the shield assembly 190 of the second arm 180 may be located proximate the upper chest of a user. FIG. 2B illustrates a configuration of the communications headset 100 wherein the first arm 160 is in an inactive position and the second arm 180 is in an engaged position. When the second arm 180 is in the engaged position, the shield assembly 182 of the second arm 180 may be located proximate the mouth and nose of the user, completely enclosing the area to hinder the entrance and exit of airborne particles. When the first arm 160 is in the inactive position, the microphone 162 of the first arm 160 may be located proximate the upper chest of a user and away from the mouth of the user, thereby creating distance between microphone 162 and the mouth of the use so that unwanted sound input is not communicated through the microphone 162. Additionally or alternatively, the first arm 160 and/or second arm 160 may also be pivotable to inactive positions above the head of the user, e.g., above or adjacent to the support band 140 to achieve a similar effect. In one embodiment, the first arm 160 may only be pivotable between an engaged position in front of the mouth of the user and an inactive position above the head of the user, while the second arm 180 may only be pivotable between an engaged position covering the mouth of the user and an inactive position proximate the chest of the user, whereby the first and second arms 160, 180 would not collide when both are placed in the inactive position.

[0040] In another embodiment, as shown in FIG. 3, the first arm 160 and second arm 180 may be pivotable about a vertical axis such that the first arm 160 and the second arm 180 rotate in an outward direction away from the mouth of the user, whereby, in an inactive position, the first arm 160 and second arm 180 may be positioned laterally to the side of the head of the user. The first arm 160 or the second arm 180 may then be rotated inward about its respective vertical axis to place the first arm 160 or the second arm 180 in the engaged position. It is within the scope of this disclosure that the communications headset 100 may employ both pivot systems, allowing for the pivoting of the arms 160, 180 upwardly/downwardly and outwardly.

In this embodiment, the microphone 162 of the first arm 160 or the second microphone of the second arm 180 and the speaker 120 may be used as external microphones and speakers for a cellular telephone, thereby allowing a user to make and receive calls from a cellular telephone in proximity to the headset system 100. One or more buttons may be disposed at the first end 144 or the second end 146 that may correspond to powering the headset system 100, the raising of volume in the speaker 120, the changing of radio channels for the headset system 100, or other commands known in the art.

[0052] In another embodiment, an example of which is shown in FIG. 5, the support band 140 may be comprised of a semi-rigid material and adapted to be supported by the neck and collar of user. The support band 140 may be configured in a semi-circular shape, whereby the elongated body 142 of the support band 140 is wrapped around a back of the neck of the user when worn and wherein the first end 144 and the second end 146 are proximate the front of the neck of the user. In various configurations, the headset 100 may include one or more ear covers 122 configured to position over ears of a user. Ear covers 122 may be positioned along first and second ends 144, 146 at locations corresponding to ears of the user. Ear covers 122 may include a speaker 120 in some embodiments. In one embodiment, only the second arm 180 comprising the shield assembly 190 is attached to the neck-supported support band 140, whereby the speakers 120 and the first arm 160 and microphone 162 are not present. In another embodiment, all features presented in the head-supported communications headset 100 are present. The one or more speakers 120 of the communications headset 100 may extend vertically from the support band 140 to a location proximate the ears of the user. The first arm 160 and the second arm 180 may be configured in a similar fashion to the head-supported communications headset 100 of FIGS. 1-3, whereby the first arm 160 and the second arm 180 are disposed at the first end 144 and the second end 146 of the support band 140, respectively. In this embodiment, the first arm 160 and the second arm 180 may be pivotable about an attachment point at the distal end 144 and the second end 146 of the support band 140, respectively. The first arm 160 and the second arm 180 may extend substantially vertical when in an engaged position to a position proximate the mouth and nose of the user. In an inactive position, the first arm 160 and the second arm 180 may extend substantially downward and rest upon the chest of the user.

[0053] The support band 140 may comprise a semi-rigid metal adapted to be manipulated by the user to configure the support band 140 into a desired shape. Thus, the shape of the support band 140 may be changed to accommodate specific dimensions of the neck of the user currently wearing the communication headset 100.

[0054] In one embodiment, the first arm 160 and second arm 180 are removably attachable to the support band 140. In this embodiment, the first arm 160 may be removed to allow for the operation of the communications headset system 100 with solely the second arm 180 attached or the second arm 180 may be removed to allow for the operation of the communications headset system 100 with solely the first arm 160. In one embodiment, the first arm 160 and second arm 180 may also be removably attachable and configured to receive the opposite end 144, 146 of the support band 140, whereby the first arm 160 and the second arm 180 may switch sides relative to the head of the user. For example, if a starting configuration of the communications headset 100 comprises the first arm 160 disposed to the left of the head and the second arm 180 to the right of the head, and a user prefers the shield assembly 190 of the second arm 180 to the left of the head, the user may detach the first arm 160 and the second arm 180 from the support band 140 and reattach the second arm 180 to the left of the head and the first arm 160 to the right of the head.

[0055] With reference to the example embodiment of FIG. 6, a wrist-mounted shield assembly 200 is disclosed. In one embodiment, wrist-mounted shield assembly 200 comprises a wrist band 210, a pivotable arm 220, and a mask assembly 230. The wrist band 210 is adapted to secure the wrist-mounted shield assembly 200 to the forearm of a user. The pivotable arm 220 is secured to an outer face of the wrist band 210 at a connection point and the mask assembly 230 is disposed on an opposite end of the pivotable arm 220. In one embodiment, the connection point is a simple pin joint allowing for a single degree of rotation. In another embodiment, the connection point between the pivotable arm 220 and the wrist band 210 allows for multiple degrees of freedom, whereby the arm may be positioned in different configurations.

[0056] In a closed position, as depicted in FIG. 7A, the pivotable arm 220 may be aligned approximately parallel with the arm of the user, with the mask assembly 230 located at an upper area of the forearm. As shown in FIG. 7B, the pivotable arm 220 may be rotated about the connection point to an erect position, whereby pivotable arm 220 is positioned perpendicular to the forearm of the user. In the erect position, the user may lift the fore arm near the face of the user to engage the mask assembly 230 against the face of the user. The mask assembly 230 may comprise a similar configuration and similar features to the shield assembly 190 of the previous embodiments. In one embodiment, a connection point between the pivotable arm 220 and the mask assembly 230 may comprise a hinge, whereby the mask assembly 230 may pivot relative to the pivotable arm 220 to allow for ease of use and more versatility when the mask assembly 230 is engaged with the face of the user.

[0057] In the erect position, a user may lift its arm to a height below its chin and position the mask assembly 230 to press against the face of the user to completely cover the nose and mouth of the user. The pivotable arm 220 may be approximately eight inches in length. In one embodiment, the pivotable arm 220 may be telescoping, whereby the length may be increased or decreased depending on the preference of the user. In one embodiment, the pivotable arm 220 may further comprise a second joint along its length, whereby the pivotable arm 220 may fold upon itself In this embodiment, the mask assembly 230 may be positioned proximate the wrist of the user when in the closed position. The wrist band 210 may be positioned proximate the wrist of the user and comprise a single strap that is secured about the wrist. In another embodiment, the wrist band 210 may comprise multiple straps connected by a connection rod running the length of the forearm of the user, thereby increasing the stability of the wrist-mounted shield assembly 200. The wrist-mounted shield assembly 200 may further comprise a third microphone and radio components in operational communication with the headset assembly 100, whereby sound input through the third microphone may be transmitted to the communication unit 126 of the communications headset 100. The one or more straps of the wrist band 210 may comprise hook and loop fasters, whereby the strap may be wrapped around the wrist or forearm of the user and a portion of the strap comprising hooks may be compressed against a portion of the strap comprising loops, thereby securing the one or more straps in place. Alternatively, the one or more straps may be comprised of an elastic fabric, such as conventional cotton wristbands, that are stretched, slid over wrist, and secured on the forearm via compression caused by an elastic force of the fabric.
