    摘要: A one-piece housing holds an image sensing module having a transparent image sensing surface and a document drive roller in close alignment. A cover closely fits around the housing and is positioned in close alignment with respect to the housing. The cover and housing cooperate to define a document entry path in which a plurality of sensors are located: a set of document-skew-detecting sensors and a set of document-insertion-detecting sensors, the sets of sensors acting independently of each other. The number and spacing of the sensors is the set of document-insertion-detecting sensors is such that the narrowest expected document encounters at least one such sensor. The cover and housing also cooperated to define a document scanning path and one or more document exit paths. The cover includes a movable member adjustable by a user to either one of two positions, the member cooperating with the cover and housing to define a first document exit path directing documents toward the user and a second document exit path directing documents away from the user. The cover includes a plurality of cover portions, the cover portions interlocking to accurately position the cover portions with respect to each other and the housing.

    摘要: A laptop computer (10) with a tiltable and swivelable display (12) is connected to case (29) by a pivot mechanism (20) and a swivel mechanism (33). In the pivot mechanism (20), a first pivot (22) connects display (12) to a pivot plate (50), and the second pivot (24) connects the pivot plate (50) to base (32) of the display (12). The first pivot (22) consists of a pair of pivot pins (52) on each end of the pivot plate (50). The second pivot (24) consists of split pivot pins (54) at each end of the pivot plate (50). The pivot pins (54) and inboard shafts (58) are fastened together and inboard shafts (58) rotate within outboard shafts (56). The outboard shafts (56) and the inboard shafts (58) are surrounded by clutch springs (60), which are connected so that the clutches are in their free rotating direction, i.e., does not resist motion between them when the display is being opened, and which resist motion between the inboard shafts (58) and outboard shafts (56) when the display is being lowered, to produce a greater friction than produced by the first pivot (22). The swivel mechanism (33) consists of a first swivel member (70) fixedly attached to case (29) and a second swivel member (72) which is fixedly attached to display base (32) and nests inside the first swivel member (70). The second swivel member (72) rotates inside the first swivel member (70).

    摘要: A portable apparatus for measuring the electrochemical characteristics of a sample is disclosed. A disposable cartridge, including a plurality of interconnected flow chambers, houses a printed circuit board substrate upon which reference and indicating electrodes are formed. The electrodes are employed in the presence of chemical reagents to aid in the electrochemical determination of a sample undergoing analysis. A thermal sensing element is in close proximity to the electrodes to permit the correction of the measurement for variations in temperature. After a pH value has been determined, the used cartridge can be mechanically ejected thus eliminating user exposure to the blood sample being measured. In this way, the pH of a blood sample can be determined quickly, effectively, inexpensively and with a minimum amount of sample and reagent preparation.

    摘要: Systems and methods for brewing beverages in accordance with the present invention can improve the flavor of brewed beverages and reduce the vertical space required for a system using suction. One such assembly comprises a brewing chamber adapted to hold a filter having an intake duct for receiving fluid for brewing, and an output duct for expelling a brewed beverage. The brewing chamber is positioned above a pressurizable container, or carafe, having an adjustable standpipe and containing the fluid. The carafe has a heated base, which when heated causes pressure to build up, forcing the fluid up the standpipe, through a check valve, through the intake duct and into the filter. Once substantially all of the fluid has been urged into the brew chamber, the heat is removed, creating a partial vacuum that pulls the brewed beverage back into the carafe. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures, and the claims.
