摘要： Present novel and non-trivial optical, laser-based measuring systems and method are disclosed. An optical, laser-based, or LIDAR measuring apparatus is comprised of a radiation receiver/transmitter, a beam-forming optical element, a beam steering device comprised of a deviation optical element and at least one actuator used to steer the deviation optical element in response to drive signal(s) from a processor. A method employed by the system may be comprised of the receiver/transmitter receiving a transmitter signal from the processor and transmitting promulgated radiation; the beam-forming optical element receiving the promulgated radiation and forming a beam of radiation; the deviation optical element receiving the beam of radiation, diverting a beam of radiation, receiving a reflected signal, and diverting the reflected signal; the beam-forming optical element receiving the diverted signal, forming a converging reflected signal, and directing the converging reflected signal to the radiation receiver/transmitter which receives the converging reflected signal.

摘要： The present invention includes an apparatus and a method for transceiver self-diagnostic testing in a communication system. A feedback unit (228, 326) is utilized that allows performance of a loopback test independent of a transmit frequency to receive frequency difference without undue proliferation of circuitry.

摘要： The invention relates to a scan mode of operating for a communication system that supports both voice and data communication services. Prior to entering the scan mode, a mobile station (28) provides a message to the fixed network equipment, and particularly a data controller (22) within the fixed network equipment, that it is entering scan mode. When exiting scan mode, the mobile station (28) sends a message to the data controller (22) indicating that it is no longer in scan mode. With knowledge of whether the mobile station (28) is in scan mode, the data controller (22) sends data messages to the mobile station using a preamble. The preamble may include a plurality of short confirmed message packets (606) and each may contain a preamble list of mobile stations to which data messages are scheduled to be sent.
