Abstract: The present invention is directed most particularly to wireless communication systems for interconnection with telephone systems, and more particularly to methods and apparatus to suppress unwanted and annoying audio spikes or bursts that infiltrate the wireless system from ultimately reaching the user's earpiece. An embodiment of the invention is directed to a telephone headset amplifier system with a noise blanking or squelching capability, which attenuates the incoming audio signal when the incoming signal exceeds a predetermined threshold.

Abstract: Telephone sets can be fitted with auxiliary headset features but they will still require mechanical lifters to raise and lower the handset in response to a call. The lifter needs to be in circuit with some portion of the telephone set but it is impractical to modify an unlimited number of disparate set types. To solve this problem, the audio line cord, which is easily detachable, is passed through the lifter system and manually operable remote switch. The switch issues signals in tandem with audio signals on the handset cord and the lifter system differentiates the signals to respond only to switching signals intended to lift or lower the handset from its cradle.

Abstract: A headset with an adjustable microphone boom which can be adjusted to and from a position near the mouth of a user and is mounted in a housing by a friction part being coupled to a flexible friction coupling which is configured in a plate in that co-operating plates are stamped out of the plate and are connected to the plate by means of flexible arms. The friction part has a shaft which can be accommodated in a bearing defined by recesses which are configured partly in the inside of the housing and partly in the plate. The microphone boom, the housing and the plate with friction coupling are held together by means of a locking ring. In this way a stable, adjustable microphone boom is provided which does not become loose with time, understood in the way that no matter in which position and regardless of how frequently the position is changed, the microphone boom will remain secured with a sufficient force in the friction coupling.

Abstract: 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 (6) can be suspended in two different positions, corresponding to the communication unit being worn on the right or the left ear, respectively.

Abstract: A retainer that is attachable to a set of interfacing cables prevents physical separation of the cables while allowing electrical disconnection of the cables. The retainer uses a body member with a hinged end cap on each end. The end caps include a snap pin and the ends of the body include receiving voids for the snap pins. The end caps can be locked into place by rotating around the hinged attachment until the snap pins engage the receiving voids. Either one or both of the end cap and elongated body have notches that form restraining voids when the end caps are locked in place.

Abstract: An earring for a headset comprising a speaker and possibly a transducer or microphone, is arranged to be worn on one ear of a user so that the earring surrounds the outer ear of the user, and is arranged so that the size of the earring is adjustable. With the object of providing simple adjustment to the size of the ear of the user, the earring is produced with a hard part and a soft part, where the second part can be introduced into the first part. The adjustment of the size of the earring is effected with an adjustment button being secured to the soft part, in that the button with the soft part can be displaced in a channel, which is provided longitudinally in the hard part. The channel is possibly configured by the hard part being configured with a closing part. With the invention an adjustment arrangement for an earring for a headset is thus provided, which is easy for the user to operate, also when the earring is placed on the ear of a user.

Abstract: 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.

Abstract: A headset which consists of an ear hook and a holding ring that are interconnected by means of an attachment element formed by a hinge, which is made of a deformable, flexible material that may be an elastomer, such as EPOM, TPE or Santroprene®The hinge has a four-sided hole in which one end of the ear hook may be received, said end being formed with a four-sided shape in dimensions corresponding to the hole. Teeth are formed in the hole which are capable of cooperating with depressions formed on the four-sided end. The invention provides an attachment element which may be manipulated several times when adjusting the position of the ear hook relative to the holding ring, without play occurring in the hinge at any time, since there are no mutually movable slide bearing parts, such as shafts that can slide. In other words, a stable attachment is ensured between the ear hook and the holding ring in the positions selected by a user.
