A dental bite block is provided. The dental bite block includes a body having a first end and a second end, an outer sidewall, and an inner sidewall. The body comprises an upper biting surface positioned within an upper channel and a lower biting surface within a lower channel. The outer sidewall and the inner sidewall extend past the upper and lower biting surfaces and define the upper channel and the lower channel, respectively. The upper channel and the lower channel are each able to receive a row of teeth therein. The dental bite block prevents the biting down and provides safe access to the interior of the mouth. A handle extends from the bite block and is releasably tethered to a toothbrush such that the teeth of the subject may be brushed when the teeth are received within the mouth of the subject.

Communication unit comprising a housing in which at least one transducer is placed, and on which a microphone arm is suspended. The housing also has means, such as an ear hook, for fastening the communication unit to the head of a user. The microphone arm is pivotally connected to the housing by a hinge link, and at an outer area of the housing, so that the microphone arm can be moved between a first position in which it lies up against the housing, and a second position in which it extends away from the housing. The microphone arm has a length, which in the main is less than or of the same order as the greatest extent of the housing, so that in the folded-in state the microphone arm does not project out over the circumference of the housing. The communication unit can be used on both the right and the left side of the head, in that the ear hook () can be suspended in two different positions, corresponding to the communication unit being worn on the right or the left ear, respectively.

A microphone array for providing a focused field of optimum audio reception is disclosed. The array has a series of interconnected microphones spaced within a housing. At a midpoint of the spaced microphones is an illuminated polarized centering marker which gives the user a visual signal that the user is located within the optimum filed of audio reception. The housing can be placed on the top front edge of video monitor and has slideably mounted removable feet, which allow the microphones to be aimed more accurately at the user. The array is foldable along a midpoint, which allow for compact storage. The folding mechanism is a hinge, which has a hollow core, and openings which allow the internal wiring to interconnect two wings of the array without exposing the wires. The wings are held in their longitudinally oriented position by a latching mechanism of pins in one wing which snap fit into capture boots within the other wing. Microphones are maintained in sound deadening pods, which absorb side and rear audio signals and provide rear pressure relief.
