Abstract: A method of calibration in a radiation delivery system. The method including acquiring, using a camera, an image of a radiation beam incident on a phantom, wherein the radiation beam being emitted by a radiation source of the radiation delivery system and the phantom comprising an X-ray luminescent material. The method further including determining a beam pointing offset based on the image. The method further including calibrating a position of the radiation source of the radiation delivery system based on the beam pointing offset and a relative position of the camera with respect to a beam axis of the radiation beam.

Abstract: Method for transferring service for a mobile station call signal from a first base transceiver station to a second base transceiver station in a wireless mobile telecommunication system, while a call is in progress. The method can include receiving at a base transceiver station an access burst from a mobile station with a call already in progress and requiring service from the base transceiver station. Based on the received access burst, the base transceiver station can electronically steer a beam of an adaptive antenna array of the base transceiver station toward a location of the mobile station.

Abstract: A method for calibration of RF paths of a frequency hopping adaptive base transceiver station is provided. The method of calibration calibrates a wireless cellular telecommunication system with a frequency hopping adaptive base transceiver station including an adaptive antenna array with two or more RF traffic transceiver apparatus chains. The wireless cellular telecommunication system communicates with mobile units on a frequencies defined by a hop list. The method of calibration includes the step of periodically interrupting a frequency hopping process of the frequency hopping adaptive base transceiver station while calls are in progress. The method of calibration further includes the step of calibrating an antenna transmit path for a RF traffic transceiver apparatus chain at a frequency selected to include one or more frequencies in the hop list to determine a set of weighting parameters for the antenna transmit path at the one or more frequencies.

Abstract: An inspection system (200) is for inspecting power generation equipment (202) and includes a remote receiving device (134) which receives images captured and transmitted by an inspection apparatus (100). A recording device (142) records the images thereby providing a permanent record of the inspection. The inspection apparatus (100) comprises: a flashlight assembly (102) including a power supply (110), an elongated housing (104) having first and second ends (105,107), a lens body (120) coupled to the first end (105), and a lens cover (114) covering the lens body (120). The inspection apparatus (100) further includes an imaging system (122) having a camera (130), such as a wireless video camera, which is disposed within the lens body opening (121), an illumination assembly (106) which generally surrounds the camera (130), and a protective cover (116) for the illumination assembly (106). An associated method is also disclosed.
