Abstract: A media identification system is provided. The system comprises an audio input configured to receive an audio signal, and an audio clip extraction module configured to extract an audio clip from the audio signal. The system further comprises an audio clip processing module configured to generate metadata based upon the audio clip, and a first communication interface configured to transmit media identification data corresponding to the audio clip to a media identification server when the metadata based upon the audio clip meets a predetermined requirement, wherein the predetermined requirement comprises the metadata indicating that the audio clip comprises music.

Abstract: An audio interface system is disclosed that receives an audio signal from an audio line and outputs a normalised audio signal. An audio interface device of the audio interface system comprises a signal conditioning module, a gain module to apply a gain to the audio signal and an attenuation module to apply an attenuation to the audio signal to output the normalised audio signal. The audio interface device further comprises an interface configured to communicate the normalised signal to an external device. In response to determining that an amplitude of the audio signal does not meet a minimum amplitude requirement or exceed a maximum amplitude requirement, the signal conditioning module is to adjust the amplitude of the audio signal by applying the gain and/or attenuation to meet the requirement.

Abstract: There is provided an anode for a magnetron, the anode comprising: a cylindrical shell defining a longitudinal axis, a centre of the shell for accommodating a cathode of the magnetron; a plurality of vanes arranged at angular intervals around the shell, wherein an angular separation between each vane and its adjacent vane is configured to provide a cavity resonator of the magnetron, wherein each vane has a width extending radially inwardly from the shell toward the centre of the shell, and has a length extending longitudinally in parallel with the longitudinal axis of the shell; and a plurality of annular strap rings for setting a resonant mode spectrum of the cavity resonator, wherein the strap rings are arranged at longitudinal intervals and concentrically with the longitudinal axis of the shell, wherein alternate vanes are configured to support the alternate strap rings, such that each vane couples alternate strap rings and each strap ring couples alternate vanes, wherein a cross-sectional dimension of at l

Abstract: An electrical arrangement, which may, for example be a magnetron, has a sealed chamber and electrically insulating fluid contained within the chamber. A temperature expansion compensation bladder comprising a helical tube is located within the chamber, the helical tube having an end open to ambient atmosphere outside the chamber, and having a closed end within the chamber.

Abstract: An electrical arrangement, which may, for example be a magnetron, has a sealed chamber 12 and electrically insulating fluid contained within the chamber. A temperature expansion compensation bladder comprising a helical tube 13 is located within the chamber 12, the helical tube 13 having an end 15 open to ambient atmosphere outside the chamber 12 and having a closed end 14 within the chamber.

Abstract: A lift assist device for a slide-out room includes a base and a floor support having a fixed portion, a deflecting portion, and a biasing member disposed between the base and the deflecting portion. When the slide out room is in an extended position, the weight of the room deflects the deflecting portion, thereby compressing the biasing member. As the slide-out room is being retracted from the extended position, the biasing member decompresses, thereby facilitating lifting of the slide-out room.

Abstract: An improved device and method of lubrication for a tongue jack, 5th wheel jack, or other jack or other threaded positioning device. Ports are provided in the inner and outer tubes of the jack. The aligned ports provide access to a lubrication cavity in the jacknut. The lubrication cavity may include a grease fitting such as a zerk fitting. When the ports are in alignment, a grease gun can be inserted easily to the zerk fitting to apply grease to the interior structure of the nut as well as to the threads of the jackscrew. The lubricant may be introduced directly at a region of contact between a screw and the load bearing element. Applicant's test results show that this improved lubrication can increase the life cycle of the jack by more than 100%.

Abstract: A hinged two-part doorstop wedge that can be folded into a generally flat or collapsed configuration, and which can be unfolded and deployed in an elevated configuration for placement on the ground near a door so as to stop the motion of the door. The doorstop includes pivotally coupled first and second hinge elements, wherein in the fully collapsed configuration the first hinge element and the second hinge element have generally coplanar upper and lower surfaces, and when in the elevated configuration the top side of the first hinge element is angled upwardly to engage the bottom rail of a door.
