Abstract: Communication unit comprising a housing (1) in which at least one transducer is placed, and on which a microphone arm (2) is suspended. The housing also has an ear hook (6) for fastening the communication unit to the head of a user. The microphone arm (2) is pivotally connected to the housing (1) by a hinge link (3,4,5) at an outer area of the housing, and so that the microphone arm (2) can be moved between a position in which it lies up against the housing (1), and a 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.

Abstract: A wireless system is provided which enables a remotely located equipment monitor to control the equipment in the event that more than one alert or alarm for the same fault condition, at the equipment have been ignored by the equipment operator. Control options include instructing the operator to shut equipment down, automatically shutting the equipment down and putting the equipment in a safe mode of operation.

Abstract: Method and apparatus for detecting cargo state in a delivery vehicle. A method is provided for determining a cargo state in a delivery vehicle. The method includes sensing a cargo state change, and determining whether or not the delivery vehicle is in motion. The method also includes storing the cargo state change if it is determined that the delivery vehicle is not in motion.

Abstract: A headset (1, 10, 30) e.g. for use in connection with wireless communication by means of Bluetooth technology in connection with mobile telephones, PSTN telephones and the like, which comprises a housing (2, 3, 11, 28) with a transducer (5, 12, 27) in the form of a speaker, as well as a microphone (4, 14, 29) and an ear hook (6, 23, 28). In a first embodiment, the housing may be constructed as two shells (2, 3) which may be opened and closed so that all mechanical parts may be concealed on the housing when the headset (1, 10, 30) is not in use, thereby ensuring that the various parts are not damaged when the headset is stored in a pocket. The shells (2, 3) may be interconnected by means of a hinge (7, 8) which has an axis disposed in the same plane as the surface of the shells. Alternatively, the shells may be arranged such that the axis is disposed in a perpendicular plane relative to the surface of the shells.

Abstract: A method and apparatus for determining whether cargo is present in a freight car. The freight car has a proximal (“rear”) end with a loading door and opposing, distal (“front”) end. One or more transmitters and receivers are mounted inside the freight car at the front end, toward the car's ceiling. The transmitters/receivers are operated by a controller, which also functions to analyze data from the transmitters/receivers and transmit related reports to a remote monitoring site. During a prescribed time period, a transmitter generates an ultrasonic signal pattern with a coverage area of prescribed radius that terminates before reaching the loading door. During the time period of transmission, or slightly later to account for signal reflection time, the controller operates the receiver to detect reflected signals originating from the transmitter.

Abstract: An on-line indicator (40) for the multipurpose headset amplifier comprises a holder in two parts (45) arranged to be snapped onto the ascending, holder (10) which is mounted on the housing (5) of the multipurpose headset amplifier. The on-line indicator has a rotatable indicator or light emitting diode (41) which is coupled to the multipurpose headset amplifier by means of a cable (42). The light diode will light up when the headset is in use to indicate to others that the user of the headset is on the line.
