Abstract: Disclosed herein is a method of determining the nature of a fault in a radiotherapy device comprising a linear accelerator. The radiotherapy device is configured to provide therapeutic radiation to a patient. The radiotherapy device comprises a vacuum tube comprising an electron gun, a waveguide configured to accelerate electrons emitted by the electron gun toward a target to produce said radiation, and a flight tube. The electron gun is located at a first end of the vacuum tube and the flight tube is located at a second end of the vacuum tube. The radiotherapy device further comprises a first and a second sensor. The first sensor is configured to provide signals indicative of pressure at a first region inside the vacuum tube and the second sensor is configured to provide signals indicative of pressure at a second region inside the vacuum tube. The first region is closer to the first end of the vacuum tube than the second region is.

Abstract: A phantom, phantom system, and method of phantom identification include a first material that forms a phantom. A phantom identifier includes at least one unit marker. The at least one unit marker identifies a physical characteristic of the phantom. In a method of phantom identification, an image of the phantom is obtained that includes the phantom identifier. The at least one unit marker is identified, the at least one unit marker encodes a value representative of a physical characteristic of the phantom.

Abstract: Described is a method of determining whether repair or replacement of an electron gun of a radiotherapy device should be scheduled. The radiotherapy device comprises a linear accelerator and is configured to provide therapeutic radiation to a patient. The radiotherapy device comprises a vacuum tube comprising the electron gun, a waveguide configured to accelerate electrons emitted by the electron gun toward a target to produce said radiation. The radiotherapy device comprises also comprises a current sensor, the current sensor being configured to provide signals indicative of current supplied to the electron gun. The method comprises receiving a current value, processing the current value, and based on the processing of the current value, determining whether repair or replacement of the electron gun should be scheduled.

Abstract: A heat exchanger includes a header and a side plate. The header has a face plate that defines a plurality of orifices. The header has a protrusion that extends outward from the header and down such that a gap is formed between the header and the protrusion. An external portion of the protrusion is configured to break away from the header during thermal expansion. The side plate is disposed adjacent to an array of alternating tubes and fins. Each tube extends into one of the orifices of the plurality of orifices. The side plate has an end that is secured to the external portion of the protrusion.

Abstract: A header tank of a heat exchanger. The header tank includes a housing defining a coolant chamber through which coolant flows. The header tank further includes a flow control member, which extends into the coolant chamber. The flow control member is configured to advantageously reduce swirling of coolant in the coolant chamber, reduce velocity of coolant in the coolant chamber, and reduce liquid pressure drop of the heat exchanger.

Abstract: Implementations are directed to identifying potential churn of a user of one or more computer-implemented systems provided by an enterprise. In some examples, actions include identifying potential churn of providing a plurality of event profiles based on historical data, each event profile being representative of interactions of users with the enterprise and corresponding to churn of the users, at least one event profile being representative of an interaction of users with the one or more computer-implemented services, providing a pulse of the user at least partially based on historical data associated with the user, and one or more event profiles of the plurality of event profiles, and determining that the user is at-risk of churn based on the pulse of the user and a risk index value, and in response, displaying an indication that the user is at-risk of churn in a graphical user interface.

Abstract: A multifluid heat exchanger includes a first tank connected to a second tank through a plurality of fluid conduits. A partition disposed inside the first tank divides an internal space of the first tank into a first space and a second space. The first space is in fluid communication with the second tank through the plurality of fluid conduits. As a result, a first internal fluid may flow from the first space to the second tank, while a second internal fluid may flow through the second space.

Abstract: An online personal merchandise cataloguing system is equipped with integrated item tracking and hosted (or imported) social network functionality. The system comprises an internet application with a supporting backend network, the pertinent configuration and operation of both being substantially under the control of an individual retailer. Accessible through an internet browser or a smartphone “app”, the internet application is configured to provide a user with means for listing or otherwise cataloguing items of merchandise. In combination with and supported by the retailer's backend computer network, the internet application enables the user to share his online catalog with an extrinsic social network and to track cataloged items.

Abstract: A radiator for a vehicle includes a built-in oil cooler tank. The radiator includes two header tanks and a core member disposed between the header tanks. One of the header tanks includes a support member disposed along an inner surface of the header tank and further defines an aperture. The oil cooler tank includes two ports and a core portion extending between the ports. Each of the ports has a rim and defines a bore. The rim of a given port is disposed within a given support member such that the bore of the given port aligns with a given aperture of the header tank.
