  • Publication number: 20210027214
    Abstract: The disclosed computer-implemented method may include identifying a personal mobility vehicle that is available to reserve for a trip, determining that at least one metric for a level of maintenance for the personal mobility vehicle indicates a need for performing the maintenance on the personal mobility vehicle, determining at least one metric for an operations effort for performing the maintenance at a current location of the personal mobility vehicle, and blocking use of the personal mobility vehicle, to facilitate the operations effort for the performing of the maintenance, based at least in part on the metric for the level of maintenance and at least in part on the metric for the operations effort indicating an advantage to performing the maintenance at the current location. Various other methods, systems, and computer-readable media are also disclosed.

  • Publication number: 20060223032
    Abstract: A method for detecting tooth decay and other tooth anomalies wherein a tooth is transilluminated with a near-infrared light source preferably in the range from approximately 795-nm to approximately 1600-nm, more preferably in the range from approximately 830-nm to approximately 1550-nm, more preferably in the range from approximately 1285-nm to approximately 1335-nm, and more preferably at a wavelength of approximately 1310-nm, and the light passing through the tooth is imaged for determining an area of decay in the tooth. The light source is a fiber-optic bundle coupled to a halogen lamp or more preferably a superluminescent diode, and the imaging device is preferably a CCD camera or a focal plane array (FPA).

  • Publication number: 20040221487
    Abstract: An article of footwear having an upper (10) with a rear portion (14) flexible enough to allow the rear part of the sole (16) to lie flat under the heel of the foot during the walking stride, and flexible enough to permit unimpeded hindfoot inversion; a level sole (16); an insole (20) with a gripping material (18) bonded to its upper surface; and a midsole (22) that provides shock absorption for the heel and forefoot without springiness. Full range of motion of the foot, balance of the foot and body, and proprioceptive and tactile sensitivity of the foot are achieved.

  • Patent number: 6522407
    Abstract: A polarization sensitive optical imaging system is used to detect changes in polarization in dental tissues to aid the diagnosis of dental disease such as caries. The degree of depolarization is measured by illuminating the dental tissue with polarized light and measuring the polarization state of the backscattered light. The polarization state of this reflected light is analyzed using optical polarimetric imaging techniques. A hand-held fiber optic dental probe is used in vivo to direct the incident beam to the dental tissue and collect the reflected light. To provide depth-resolved characterization of the dental tissue, the polarization diagnostics may be incorporated into optical coherence domain reflectometry and optical coherence tomography (OCDR/OCT) systems, which enables identification of subsurface depolarization sites associated with demineralization of enamel or bone.
