Abstract: Implementations relate to configuration of wireless communication signals between devices. In some implementations, a method includes determining a transmission scenario associated with transmission of wireless signals of a particular wireless communication protocol from a first device to a second device. The transmission scenario specifies one or more transmission characteristics for the signal transmission. A test message is sent wirelessly from the first device to the second device according to the transmission scenario, and a reply message is received from the second device in response to test message. The reply message includes one or more signal quality indicators that indicate a signal quality of the test message. The transmission scenario is selected as a designated scenario based on the signal quality indicators, and data is wirelessly transmitted from the first device to the second device according to the designated scenario.

Abstract: System and techniques are provided for preconfigured antenna beamforming. A device having a first antenna system for communicating over a first wireless link and a second antenna system for communicating over a second wireless link may be provided. For different transmit power levels of the first and/or second wireless links, an antenna coupling factor between the first antenna system and the second antenna system may be measured for different beamforming configurations of the first antenna system, a received signal strength indicator (RSSI) of the first and/or second wireless link may be measured for the different beamforming configurations of the first antenna system, and a beamforming configuration at each of the different transmit power levels with the measured antenna coupling factor and the measured RSSI may be stored in a memory as a predefined beamforming configuration.

Abstract: A method of determining preventive maintenance for an optical inspection system for inspecting photolithography processed substrates. The method includes measuring at least one operational characteristic of the optical inspection system and comparing a measurement result for said at least one operational characteristic with predetermined preventive maintenance criteria for the operational characteristic. Also included is determining a preventive maintenance requirement based on a comparison result of said comparing, and initiating a preventive maintenance action on said optical inspection system, said preventive maintenance action corresponding to said preventive maintenance requirement. A method of automatically performing preventive maintenance on an optical inspection system, and for retrofitting an optical inspection system to facilitate preventive maintenance of the optical inspection system are also disclosed.

Abstract: An engine mounting stand for small engines, and particularly adapted for motorcycle engines. The engine mounting stand includes an upright and a journal bearing, the upright is attached to a base, a rotating bracket assembly is attached to the journal bearing of the upright, the bracket assembly designed to attach to the engine mount holes of the engine, and is operative for rotatably positioning the engine so that the mechanic can access all areas of the engine. The engine mounting stand can further include an outrigger support attached to the rotating bracket assembly, and an outrigger secured to the outrigger support. The outrigger attaches to the engine and outrigger end aperture can provide further attachment support to the bracket assembly.
