Methods and apparatus for collecting a fluid sample using an integrated collection device are disclosed. The integrated collection device includes an analyte detector and a gradient means to actively and rapidly drive the transport of a sample fluid from the point of contact to the point of detection and reading. The analyte detector can include a visually-read colorimetric detector using a chemical or enzymatic detection process. The gradient means can include physical and/or chemical processes as described in more detail herein. In some embodiments, the device is provided as an occlusive patch. Preferably, the test device provides a reading immediately upon fluid contact with the analyte detector. Consequently, the time-to-result is sample volume and transport time dependent. By providing immediate or nearly immediate reading of results, the device is particularly useful in those applications in which immediate results are advantageous.

An electrographic sensor unit and method for determining the position of a user selected position thereon. The electrographic sensor unit includes a layer of a conductive material having an electrical resistivity and a surface, at least three spaced apart contact points electrically interconnected with a layer of conductive material, a processor connected to the spaced apart contacts and disposed to selectively apply a signal to each of the contact points, and a probe assembly, that includes either a stylus of a flexible conductive layer spaced apart from the layer, coupled to the processor with the stylus disposed to be positioned by a user in vicinity of a user selected position on the surface of the layer, or that position being selected with a user's finger on the flexible layer and to receive signals from the layer when the contact points have signals selectively applied thereto. The user selected position is determined by the processor from signals received from the stylus, or flexible layer, each in relation to a similar excitation of different pairs of the contact points under control of the processor. The conductive layer may be either two or three dimensional and may be a closed three dimensional shape. There may also be multiple layers with the processor being able to discern on which of those layers the user selected position is located. Further, provision is made to correct the calculated coordinates of the selected position for variations in contact resistance of each of the contact points individually. Additionally, a nonconductive skin having selected graphics printed thereon, such as a map, can be placed over the layer and the proces-sor further convert the calculated coordinates of the selected position to coordinates that relate to the graphical information printed in the skin, and even electro-nically (e.g., audio or visual) present information to the user relative to the graphical location selected as the selected position.

When the sight impaired become mobile, they often bump their heads on unseen objects and/or hazards that could result in injury. The object detection device uses signal emitting proximity sensors that alert the user to unseen objects. The object detection device notifies the user of detected objects. Stimulators contact the user to warn the user that an object has been detected and the distance between the object and the user. Each stimulator contacts the user at a specific contact point. The stimulator finger contacting the user at a specific contact point informs the user of the distance between the user and the detected object.

A rotatable circular crossection cervical pillow is manually rotated in a continuous fashion as desired by a person whenever a fresh clean contact spot is sought, or a contact spot of variable support is sought, while the pillow is still attached to a seat back. The rotatable pillow is a cylinder of medium and/or firm high density polyurethane foam. An axial through-hole in the center permits the snug insertion of a rigid length of tubing to give the pillow axial rigidity. Swivel fixtures are attached at each end of the pillow by virtue of the central tube. A fabric cover with an opening closure covers the entire polyurethane cylinder snugly. Optionally the cover may carry therapeutic imparting elements therein. Straps with adjustable buckles are attached to each swivel fixture. Therefore, the cervical pillow rotates easily while still strap-attached to the seat back.

A gear box assembly as used in an inverted portal axle or transfer case includes a drive gear and at least one driven gear in meshing engagement with the drive gear at a contact point. A gear housing closely surrounds portions of an outer circumference of the drive and driven gears to form a baffle area. The gear housing includes an discharge orifice that is located near the contact point and a fluid gallery that extends from the discharge orifice to other locations within the gear housing. As the drive gear drives the driven gear, fluid is pumped into the discharge orifice and through the fluid gallery to fluid outlets positioned at desired locations to lubricate other gear box components. Radial inlets with elongated chamfers and stator vanes can be formed within the gear housing to draw air ingested during pumping away from the discharge orifice. Additionally, a bypass loop can be used to scavenge unwanted air ingested into meshing gear teeth.
