Abstract: According to some embodiments, a method includes placing a device under test (DUT) in a test chamber and applying a pulse-modulated RF wireless test signal to the DUT in the test chamber. The method further includes detecting an acoustic output of the DUT. In addition or as an alternative to applying the pulse-modulated test signal, the test signal strength may be at a level of 30 V/m or 90 V/m. If the DUT is a telephone, it may be coupled via a voice signal path to another telephone, and an output of the other telephone may also be detected.

Abstract: Certain embodiments provide improved two-way communication devices, such as wireless headsets, including a port configured to deliver sound, a circuit board operatively connected to the port, an antenna configured to receive wireless transmissions, the antenna operatively connected to the circuit board and positioned at a first end of the circuit board and a boom including a microphone configured to receive sound, the boom operatively connected to the circuit board via a wire configured to run across a ground plane of the antenna. Certain embodiments provide fixed booms, other embodiments provide removable booms.

Abstract: An auger boring machine includes a track having an initial end and a terminal end, and the track is provided with a rack. The boring machine also includes a sled that is mounted on the track and adapted to be moved between the initial end and the terminal end of the track. The boring machine also includes a mechanism for rotating an auger on the sled and a drive system. The drive system includes a pinion which is mounted so as to engage with the rack on the track and a mechanism for rotating the pinion so as to drive the sled along the track.

Abstract: In a system for managing and selecting a service to fulfill a request, a client application can issue a message to execute a function. A service proxy can receive the message from the client application and identify one of a plurality of services to execute the function in accordance with one or more rules. Upon identifying the service to execute the function in accordance with the rules, the service proxy can send a message to the identified service to execute the function. Alternatively, the service proxy can send the identity of the identified service to the client application. The client application can then send the message to execute the function to the identified service upon receiving the identity of the identified service from the service proxy.

Abstract: A method for operating a TEM cell to determine the characteristics of a radiation source in a circuit. The circuit is placed in the TEM cell such that the relative orientation of the circuit and the TEM cell is measurable. The TEM cell provides an output signal indicative of the energy radiated by the circuit when the circuit is operated in the TEM cell. The output signal of the TEM cell is measured for at least 6 different relative orientations of the circuit and the TEM cell. The electric and magnetic dipole moments of a radiation source having an orientation and physical dimension associated therewith are determined from the measured output signals. The electric and magnetic dipole moments determined from the measured output values are compared to moments predicted by each of a plurality of antenna types to provide an estimate of the orientation of the radiation source relative to the circuit.
