  • Patent number: 8116758
    Abstract: Time-varying conditions in a wireless network are simulated using an architecture that includes an enclosure for shielding a wireless device under test (“DUT”) from electro-magnetic interference, including other wireless devices; and at least one of: (1) a communications traffic generating device operable to generate communications traffic having selected characteristics; and (2) at least one dynamically adjustable attenuator in communication with the wireless device and the traffic generator. Embodiments of the architecture include wireless test equipment for testing operating range, roaming and capacity. The attenuator is used to adjustably attenuate signals between the device and the traffic generator over time during a test, whereby motion of the device is simulated. By connecting multiple access points, each associated with a dynamically adjustable attenuator, it is possible to force the DUT to roam between access points.

  • Publication number: 20070143940
    Abstract: A combination tool for cleaning the bristles of a paintbrush includes a plurality of wire strands arrayed on said base in rows and columns, at least one blunt-edged scraper blade arrayed on said base in transversely disposed relation to a longitudinal axis of the tool, and a plurality of comb teeth arrayed on said base between the handle and the wire strands and the at least one scraper blade. The tool performs three functions at one time so that the amount of time required to clean the bristles is one-third the time required to use all three tools separately. The tool increases productivity and reduces the number of paintbrushes that must be purchased in a given time period.

  • Publication number: 20060229018
    Abstract: A modular test chassis for use in testing wireless devices includes a backplane and a channel emulation module coupled to the backplane. The channel emulation module comprises circuitry for emulating the effects of a dynamic physical environment (including air, interfering signals, interfering structures, movement, etc.) on signals in the transmission channel shared by the first and second device. Different channel emulation modules may be included in the test system depending upon the protocol, network topology or capability under test. A test module may be provided to generate traffic at multiple interfaces of SISO or MIMO DUTs to enable thorough testing of device and system behavior in the presence of emulated network traffic and fault conditions. A latency measurement system and method applies timestamps frames as they are transmit and received at the test module for improved latency measurement accuracy.
