Abstract: Some embodiments provide a method for a document viewing application. While displaying a sequence of selectable items that each correspond to a different document in a sequence of documents, the method receives selection of an item corresponding to a particular document in the sequence. The method retrieves a first set of content for displaying at least a portion of the particular document. After the first set of content is retrieved and displayed, the method retrieves content for displaying documents surrounding the particular document in the sequence of documents such that the content is available if input is received to display one of the documents surrounding the particular document in the sequence.

Abstract: A shield assembly for shielding a housing of an electro-mechanical device from a hot body includes a first sidewall and a second sidewall disposed in a spaced apart relation from each other. A third sidewall extends between the first sidewall and the second sidewall to define a space therebetween. The first, second, and third sidewalls are configured to receive the housing of the electro-mechanical device in the space defined therebetween. The shield assembly further includes a backing plate extending laterally from a bottom end of at least one of the first, second, and third sidewalls. The backing plate is releasably fastened with a bottom end of the housing. The shield assembly further includes a tab member extending away from a top end of at least one of the first, second, and third sidewalls. The tab member is releasably fastened with a bracket associated with the housing of the electro-mechanical device.

Abstract: A valve assembly may include a valve disposed in a flow path and an actuator disposed above the valve. The actuator may be configured to actuate the valve to move between an open position and a closed position. The valve may also include a rocking member disposed above the actuator and configured to move with the valve. The valve may also include a pair of first and second position sensors disposed above and parallel to the actuator. The pair of first and second position sensors may be configured to detect a position of the rocking member. The position of the rocking member may be indicative of a position of the valve.

Abstract: The present invention provides a releasably mounted retrofit system that allows a standard back-mounted child carrier to also serve as a stroller. The retrofit system comprises an adjustable handlebar apparatus and a wheel unit. Both of these can be releasably mounted to the rear frame of an existing back-mounted child carrier thereby allowing existing carriers to also function as strollers.
