Abstract: A powered golf bag cart (10) is shown which includes a frame assembly (20), a free wheel assembly (22), a drive wheel assembly (24), a power delivery assembly (26), a steering assembly (28), and a control assembly (30). For compact storage, the frame assembly (20) of the cart (10) further includes a base portion (32), central portion (34), and handle portion (36) which collapse into one another. The power delivery assembly (26) includes a drive motor (144), located in the drive wheel assembly (24). The cart (10) is steered by the steering assembly (28) changing orientation of the drive wheel assembly (24), under control of a user operating the control assembly (30). In this manner all control and motive force is applied via a single ground contacting surface in the drive wheel assembly (24).

Abstract: A cabin tent pole system (10) using side poles (14), gable poles (16), corner hubs (18), and roof hubs (20). The corner hubs (18) have two tubular members (50) which join forming a first obtuse angle (32), where a structural web (56) may be provided to help maintain the first obtuse angle (32) and strengthen the corner hub (18). Similarly the roof hubs (20) have tubular members (60) which form second obtuse angles (34) between any pair of the tubular members (60). The roof hubs (20) may include a series of webs (66) which act to maintain the angular relationships of the tubular members (60), including the second obtuse angles (34). Only larger embodiments of the tent pole system (10) require the use of ridge poles (40).

Abstract: A method for identifying the limits of an object (10) in a digitized video display (12) having a series of video frames (14). A seed (26) is introduced into an initial object (18a) in an initial frame (14b) and the seed (26) is expanded to define the limits of the initial object (18a). The modified seed (26a) is then superimposed upon a modified object (18b) and a common area (36) is identified. The common area (36) is modified to become yet another iteration of the seed (26) for continuing the operation into yet another frame (14) having a subsequent version of the object (18). The video seed fill over time method (10) proceeds until no common area (36) is identified for a specified number of frames 14.

Abstract: A hand held intra-oral video camera (10) is provided for capturing images from inside a dental patient's mouth which has a housing (24) having a distal end (26) and a handle portion (30). Within the distal end (26) a view port (32) is located and a sensor assembly (18) is mounted. The camera (10) may include a full featured objective assembly (14) and a main lens assembly (17), for suitably manipulating image content; a reflector (16) for capturing images from an angle substantially away from a longitudinal axis (12) of the housing (24); and, an illumination assembly (20) to illuminate the surface from which images are captured. The reflector (16) may provide mirrored or conventional image orientation. Wide angles of view, high resolution, and great depth of focus are provided by the camera (10) due to the absence within it of any purely image relaying optical elements. The camera (10) may integrate with other dental tools, either in permanent or temporary modular manner.

Abstract: A base bracket (10) for tents and poles is provide having a first orifice (14) for accepting a tent stake (20), a second orifice (16) for accepting an end (42) of a tent pole (24), and an tent fabric attachment mechanism (18). The tent fabric attachment mechanism (18) includes capability for adjusting tension and taking up slack in straps (26) attached to tent fabric (28). If desired, the bracket (10) 7 may be permanently attached to tent straps to prevent misplacement and loss. Options of the bracket (10) include a tent option attachment mechanism (34), for attaching common tent options like canopies and rain flies, and shaping and structurally enhancing the region (40) around the tent pole orifice (16) to better accept stresses transferred by an assembled tent into the bracket (10).

Abstract: A step motor and servo motor indexer (10) having an improved user interface (14) wherein an input capability for programming a full range of program parameters and values is provided, yet where the user input system (20) has few components. The user input system (20) for programming the indexer (10) is characterized by having a data entry unit (26) which includes only a toggle device (27) and a rotary device (28), both of which may be combined into a single component part. In addition to the typical turned clockwise and turned counter clockwise modes of the rotary device (28) the use of the rate of rotation permits an additional input mode which is used to accomplish rotational or software ballistics to input large ranges of values during programming of the indexer (10). The user interface (14) further includes a display (22), for presenting program choices and values to user during programming, and for reporting running parameters.

Abstract: A method and apparatus (10, 410) for testing magnetic media read/write head components such as a head element bar (46) and a slider assembly (546). The component to be tested is held in a head bar holding assembly (44) or an alternate head holding assembly (544), and positioned with a head gross positioning assembly (18) or a head fine positioning assembly (16) over a localized portion (50) of a flexible magnetic medium (28) which is caused to spin in relation to a stabilizer plate (20) by a media spin motor (28). The localized portion (50) is deformed to bring the localized portion (50) of the flexible magnetic medium (28) into proximity with the component under test.

Abstract: An optical convergence apparatus (10, 310) having a projection screen (12) with a plurality of display areas (14) for displaying a like plurality of images (16). The images (16) are viewed by a plurality of lens assemblies (18) placed between the projection screen (12) and the user's eye (20). Prisms (322) are optionally provided between the lens assemblies (18) and the user's eye (20) for directing the images (16) to the user's eye (20). A stereoscopic pair (424) of the optical convergence apparatus (10, 310) is provided to enable stereoscopic reference cues.
