Abstract: The present invention provides a heatable long range metal target capable of providing acoustic feedback to the user on impact and is durable to withstand the repeated vibration stress that occurs during repeated use. In a preferred embodiment, target includes a reactive target body for generating an audible feedback signal on impact by a firearm round (such as a metal gong), a heating element and a fastening structure connectable to the target body for mounting of the heating element to the target body. The target body has a front, impact surface and a rear surface and is constructed of hardened steel for withstanding repeated impact by high velocity rounds on the impact surface without penetration. The heating element heats a target region of the target and the fastening structure connects the heating element to the target body away from the impact surface. The fastening structure includes a vibration dampening portion.

Abstract: A fluid sensor assembly is provided for sensing a fluid property in-line. The assembly includes a body with a port for connecting the body to a fluid line and internal passage connecting the first port to a second port. The assembly also includes a sensor interface portion attached to the body and a fluid sensor that interfaces with the sensor interface portion. The fluid sensor includes a sensing element that communicates with the internal passage via the second port. The sensor and the body are fixably attached by an attaching portion to form a single, integrated part.

Abstract: The portability, quality and integrity of optical storage media have made such media the dominant distribution mechanism for a wide variety of audio-visual entertainment including music, films, compilations of television series, and electronic games. The primary distribution being by an initial sale or rental, followed by re-rentals and re-sale. In the later scenarios the integrity or quality of the data stored within the optical storage medium can determine the users overall satisfaction with the audio-visual entertainment, commercial rental organization or commercial re-seller. As such a method of providing a verification or certification of the data within an optical storage medium prior to its return into the distribution chain would be extremely beneficial.

Abstract: The rapid proliferation of streamed audio-visual services to users via the Internet, especially fee-based services, has increased the importance for content providers in establishing, maintaining, improving and validating the quality of service and experience they provide to the subscribers or users of their services. Accordingly, there is provided a method of determining quality metric data at the user's display in response to a provided digital multimedia stream. The quality metric data being stored for subsequent transmission to a remote server for aggregation and correlation with other quality metric data and defect related data of provided digital multimedia streams to provide service and network providers with quantified data relating to the quality of experience of users of Internet based audio-visual services. As such the quality metric data may be applied to discrete or continuous audio-visual content facilitating quality determinations for streamed content.

Abstract: A method of grading a level of damage to digital data provides a scan of the digital data for errors therein. Based on the detected errors and predetermined data based on at least one of audio human perception and human visual perception a grade of plain quality is determined. The grade of plain quality is then provided of an output from the system for interpretation by a user or a subsequent system.

Abstract: A method of attaching at least one component to a ring laser gyro block. The method may include positioning the component so that a mounting surface of the at least one component is substantially parallel to a mounting surface of the ring laser gyro block and applying a fluid adhesive to the exposed interface of the mounting surface of the at least one component and the mounting surface of the ring laser gyro block. The method also includes allowing the fluid adhesive to harden.
