  • Patent number: 9757044
    Abstract: Disclosed are devices (100), systems (500), and methods for determining the dipole densities on heart walls. In particular, a triangularization of the heart wall is performed in which the dipole density of each of multiple regions correlate to the potential measured at various located within the associated chamber of the heart. To create a database of dipole densities, mapping information recorded by multiple electrodes (316) located on one or more catheters (310) and anatomical information is used. In addition, skin electrodes may be implemented. Additionally, one or more ultrasound elements (340) are provided, such as on a clamp assembly or integral to a mapping electrode, to produce real time images of device components and surrounding structures.

  • Patent number: 9658590
    Abstract: A toner cartridge according to one example embodiment includes a housing defining a reservoir for containing toner. An exit port in fluid communication with the reservoir faces downward on a front of the housing near a first side of the housing. A first alignment guide is positioned on the first side of the housing and a second alignment guide positioned on the second side of the housing. A toner delivery system for transferring toner from the reservoir out of the exit port includes a main interface gear. A portion of the main interface gear is exposed on the front of the housing at a second side of the housing above the second alignment guide. A connector on the first side of the housing has a forward facing opening positioned above the first alignment guide. Electrical contacts are positioned within the connector and are accessible through the forward facing opening.

  • Patent number: 9541860
    Abstract: A toner cartridge according to one example embodiment includes a housing that defines a reservoir for containing toner. An exit port in fluid communication with the reservoir faces downward on the front of the housing near a first side. A toner delivery system for transferring toner from the reservoir includes a main interface gear exposed on the front of the housing near the top of the second side. A rearward facing opening is exposed at the rear of the housing near the first side of the housing for receiving a first engagement feature in an image forming device. A forward facing opening is exposed at the front of the housing near the first side of the housing for receiving a second engagement feature in the image forming device. The forward facing opening overlaps with the rearward facing in a side-to-side dimension of the housing.

  • Patent number: 9417603
    Abstract: A toner cartridge for an image forming device according to one example embodiment includes a housing having a reservoir for containing toner therein. The housing has an exit port on a front of the housing in fluid communication with the reservoir. A first leg and a second leg each project from a bottom of the housing and extend primarily along a front-to-rear dimension of the housing. A first alignment guide is positioned on a first side of the housing and a second alignment guide is positioned on a second side of the housing. Each alignment guide extends primarily along the front-to-rear dimension of the housing. The first alignment guide includes a pair of rounded contact points and the second alignment guide includes a rounded contact point. The rounded contact points of the first and second alignment control the vertical position of the toner cartridge in the image forming device.

  • Publication number: 20160192902
    Abstract: Disclosed are devices, systems, and methods for determining the dipole densities on a cardiac surface using electrodes positioned on a torso of a patient. Electrodes are integrated into a piece of clothing worn by a patient. The clothing serves to fix the position of the electrodes adjacent a patient's torso. Ultrasonic transducers and sensors are used to determine a distance between the epicardial surface and the electrodes and are also used to detect epicardial surface motion as well as epicardial wall thickness.

  • Patent number: 9323178
    Abstract: A toner cartridge according to one example embodiment includes a housing having a reservoir for containing toner therein. An exit port in fluid communication with the reservoir faces downward on a front of the housing near a first side of the housing. A portion of a main interface gear for providing rotational power to a toner delivery system is exposed on the front of the housing near a top of a second side of the housing and engagable with a corresponding drive gear in the image forming device. A projection extends forward from the housing further forward than a frontmost portion of the exit port and is spaced from the exit port toward the first side of the housing. A front of the projection is unobstructed for engaging a developer unit when the toner cartridge is inserted into the image forming device.
