摘要： An optical sensor generates blood pressure data by obtaining two dimensional images of the surface of the patient's body, such as in the vicinity of the radial artery in the wrist area. Blood flow in the patient causes light to be reflected off a flexible reflective surface applied against the patient with a hold down pressure, and the scattering of light is sensed with a two-dimensional array of photo-detectors. The output of the photo-detectors during systolic and diastolic events is calibrated against known blood pressure measurements taken with a conventional air-cuff sphygmomanometer. Linear calibration relationships between output signal and blood pressure are obtained during calibration for some set of the photo-detectors. When blood pressure data is obtained from the patient, the linear calibration relationship between output signals and blood pressure is applied to the output signals from the set of photo-detectors, resulting in blood pressure data. The method provides for compensation for changes in hold down pressure and translation or rotation of the optical sensor relative to the patient. A preferred optical sensor arrangement for use in performing the method is also described.

摘要： An eye implant for treating glaucoma includes a main conduit and a plurality of anchor members formed from a first resilient material. The anchor members are formed such that they are biased to a relaxed condition in a non-aligned position relative to the conduit. To facilitate insertion of the implant into the eye in a minimally invasive surgical procedure, the anchor members are secured together in an aligned condition relative to the conduit with a bonding material. A cutting surface or element is also applied to the anchor members to allow the implant to be inserted directly through the wall of the sclera. The cutting surface is formed of a second material different from the first material. The second material is adapted to dissolve or melt after the implant has been inserted into the eye. Similarly, the bonding material holding the anchor members together in an aligned condition can be made from a dissolveable or heat sensitive material to allow the anchor members to relax to their non-aligned position after insertion into the eye. In the non-aligned position, the anchor members secure the implant to the wall of the sclera. Alternatively, the bonding material holding the anchors together could be made from a material that is ablated away with a laser after the implant has been inserted into the eye.

摘要： A measurement device (103) and method determines various metrics between a vehicle (101) and a ground surface (105) using a transmitter-antenna (109) for emitting energy including a portion directed down toward the ground surface. A receiving antenna (115), has a portion oriented facing toward the transmitter-antenna for receiving a portion of the emitting energy along a direct path (117), and a portion oriented facing downwardly toward the ground surface for receiving a portion of the emitting energy reflected from the ground surface along a reflected path (113). A decoder provides separate indications of forward (121) and sideward (123) velocity relative to motion of the vehicle along the ground surface. Furthermore, the decoder comprises means for determining vehicle height (125) dependent on a measured difference in path length, vehicle level (127), or front to rear tilt angle, dependent on polarization elliptical ratio changes, and road surface conditions (129) dependent on amplitude and phase changes that occur versus time.

摘要： A device and method for sensing linear displacements between a first member (101) and a second member (102) on a same axis (108). The second member (102) substantially encompasses the first member (101). To sense the linear displacements, an optical code pattern (103) is placed on the first member (101) and an encircling optical sensor (104) is placed on the second member (102). The encircling optical sensor (104) includes light transmitting (106) and receiving (107) paths that transmit and receive light to/from the optical code pattern (103). The light received from the optical code pattern (103) is sent to a displacement calculation device (105) that determines the linear displacement of the first member (101) with respect to the second member (102). Using this technique, linear displacements of the first member (101) with respect to the second member (102) can be accurately measured in high temperature environments without adversely affecting electrical components associated with the displacement calculation device (105).

摘要： Engine performance is optimized by storing a plurality of engine strategy maps (A, B, etc.), each such map containing desired engine performance characteristics, and selecting one such map by using fuzzy logic techniques to evaluate selected engine sensor output signals. Preferably, a new engine strategy map is not selected unless (1) additional fuel has been added to the vehicle's fuel tank; and (2) selected sensor output signals have experienced at least a minimum deviation from their nominal values, thus indicating that a different blend of fuel is being supplied to the engine.
