  • Patent number: 11948220
    Abstract: The disclosed computer-implemented method may include dynamically selecting transportation options to present to a transportation requestor device based on current transportation network conditions and transportation requestor device history. In some embodiments, transportation network may have many different ways of arranging a transportation requestor's trip, such as private rides, shared rides, immediate rides, and delayed rides. In some examples, the requestor's choice of transportation option may have an impact on the transportation network. In anticipation of or in response to a transportation request, the method may determine which transportation options will better benefit the transportation network and determine which transportation options to display to the requestor and/or the prominence with which the transportation products are displayed. Various other methods, systems, and computer-readable media are also disclosed.

  • Patent number: 11376163
    Abstract: Disclosed are devices, systems, and methods for restoring vision to a subject. In one embodiment, the vision restoration device comprises a projector configured to project one or more digital images onto a central retina of the subject and one or more lenses coupled to the projector and configured to focus the one or more digital images. The vision restoration device can also comprise an extraocular component configured to be implanted within the subject and comprising one or more processors programmed to execute instructions stored in a memory to wirelessly receive the one or more digital images from an extracorporeal device. The intraocular projection component can be connected or coupled to the extraocular component by a trans-scleral communication wire configured to cross the sclera of the eye. The trans-scleral communication wire is configured to transmit digital data between the extraocular component and the intraocular projection component.

  • Patent number: 11002623
    Abstract: Tension monitoring is described using a sensor which may exhibit an offset for which compensation may be provided to produce a zero voltage amplified output or to increase dynamic range. An arrangement determines whether a power reset is responsive to a battery bounce such that an initially-measured system start-up parameter can be retained. The start-up parameter is automatically saved at start-up if the power reset is responsive to a start-up from a shut-down condition. The start-up parameter may be a zero tension amplified output responsive to the sensor offset at zero tension. Protection of a tension data set is provided such that no opportunity for altering the data set is presented prior to transfer of the data set. A housing configuration forms part of an electrical power circuit for providing electrical power to an electronics package from a battery.

  • Patent number: 10281347
    Abstract: A tension monitoring apparatus is used for installing an underground utility by retraction that is applied to the utility. The tension monitoring apparatus includes a sensor for inground sensing of the tension force that is applied to the utility to produce a sensor signal. A processor monitors the tension force in a series of measurement intervals such that a plurality of tension force readings is generated for each of the measurement intervals. The processor stores a data set including a maximum tension force selected from the plurality of tension force readings for each one of the measurement intervals and copies the data set to a different location to create a copied data set after installation of the utility for subsequent selection and presentation of an overall maximum tension force.
