| 20090322355 | OBJECT POSITION SENSING APPARATUS - An object position sensing apparatus including a substrate, a conductive crossbar, and a plurality of resistive elements coupled to the crossbar is described. The resistive elements are coupled to circuitry that can apply an excitation signal, such as a voltage change, to the resistive elements. For each resistive element, an electrical effect responsive to the excitation signal, such as a change in charge flowing to the resistive element, is determined. When an object is proximate to the plurality of resistive elements, the electrical effects change, and a position of the object in one or multiple dimensions can be determined from changes in the electrical effects. | 12-31-2009 |

| 20090021267 | Variably dimensioned capacitance sensor elements - A capacitance sensing apparatus includes capacitance sensor elements covered by a layer of material. The layer of material has an uneven effect on a measure of capacitance induced in the capacitance sensor elements when an object is in proximity to a sensing surface. For example, the layer of material may have a non-uniform thickness, or a property of the material may be non-uniform across the layer. The capacitance sensor elements are dimensioned to compensate for the effect. | 01-22-2009 |

| 20090154655 | RADIOLOGICAL SCANNING ORIENTATION INDICATOR - A radiological imaging orientation indicator includes a linear indication member having a substantially uniform cross-sectional shape and means for positioning the indication member adjacent a patient's body. When the indication member is located adjacent the patient's body and a sectional scanning image is produced, a cross-section of the indication member will appear in the scanning image, indicating an orientation of the patient's body with respect to the scanning image. The linear indication member is in the form of either of an extruded letter, number and symbol which may be hollow with one or more liquids trapped inside to indicate vertical orientation. The means for positioning the indication member include pants, vests, caps, visors, eyeglass frames, sandals, gloves and collars that can only be attached to a patient's body in one way, thereby preventing confusion in determining the orientation of a scanning image. The invention includes orientation indicators for standard X-rays. | 06-18-2009 |
