Abstract: A movable bed liner hinged at the back end for converting a pickup truck into a dump truck. A pair of linear hydraulic rams disposed in respective compartments in front of the wheel wells is operable to raise and lower the dump body liner. This invention uses otherwise unusable, “dead” space in front of the wheel wells and preserves the appearance of a normal flatbed pickup truck.

Abstract: An attention performance test uses a visual display, a test subject input device, a memory and a programmed processor coupled to each of the above to administer a test to a test subject. A test target, which for example can be a word colored in a first color but meaning another color, is attempted to be matched by the test subject to one of a series of sequentially presented visual response targets. In one embodiment, a nonvisual test stimulus is also provided to the test subject, the test subject having previously been instructed to respond to the nonvisual test stimulus (such as a beep) in a particular way. The test also measures the response latency of the test subject, i.e., whether the test subject has assumed a correct position for entering a response. The responses from the test subject are recorded and may be compared with data derived from a test subject database in assessing whether an attention deficit disorder exists.

Abstract: A visual field test device (10) is disclosed which allows a larger area of the visual field to be examined and allows use of the device for testing for diseases of the eye and brain, for example, glaucoma. The device consists of a chart (12) which has visual target patterns (13) for the left and right eyes and which is foldable about fold line (45) so that the visual targets are on front and rear surfaces of the device (10). Each visual target consists of about 60 fixation targets (14), represented by sequential numbers, arranged to spiral outwards along lines (16) to facilitate use by test subjects. A plurality of test stimuli (21) are located on a rotatable disc (18) and the chart (12) has a central aperture (20) through which a selected test stimuli (21) can be viewed. Different test stimuli can be used as required and in one embodiment a moveable cover (22) can be used to obscure the test stimuli.

Abstract: Nubbed grips for hand-rotatable bicycle gear shifters have longitudinally elongated groups of nubs (50) that are angularly spaced apart by valley regions (44). Preferably, the elastomeric nubs are formed both on a cylindrical portion and an adjacent flanged portion of the grip.
