Abstract: The disclosure relates to managing a fleet of autonomous vehicles. For instance, a method may include receiving, from a plurality of the autonomous vehicles of the fleet, reports identifying locations of detected puddles. A miles per puddle rate may be determined based on the received reports. An operating policy for the fleet may be determined based on the miles per puddle rate. An instruction may be sent to one or more of the autonomous vehicles of the fleet in order to implement the operating policy.

Abstract: An interactive system can utilize microtechnology (e.g., a micro-electromechanical system (MEMS)), such as miniaturized microphone (e.g., a bone-conducting microphone), audio output device, microprocessor, and signal conversion and propagation means to create a personal area network (PAN) for a user. The system can include a voice input device (e.g., worn on one or more teeth of the user) that outputs a near-field magnetic induction (NFMI) signal based on a whisper input by the user. The NFMI signal is either detected by the user's mobile device, or converted into a wireless signal (e.g., a Bluetooth RF signal) detectable by the user's mobile device, for receiving voice commands (e.g., to provide personal assistant services) via a designated application running on the mobile device.

Abstract: Methods and systems for measuring one or more properties of a sample are disclosed. The methods and systems can include multiplexing measurements of signals associated with a plurality of wavelengths without adding any signal independent noise and without increasing the total measurement time. One or more levels of encoding, where, in some examples, a level of encoding can be nested within one or more other levels of encoding. Multiplexing can include wavelength, position, and detector state multiplexing. In some examples, SNR can be enhanced by grouping together one or more signals based on one or more properties including, but not limited to, signal intensity, drift properties, optical power detected, wavelength, location within one or more components, material properties of the light sources, and electrical power. In some examples, the system can be configured for optimizing the conditions of each group individually based on the properties of a given group.

Abstract: A microtomy system includes a tissue chuck configured to accept a tissue block and a microtome blade configured to remove one or more tissue sections from the tissue block, the microtome blade being axially offset from the tissue chuck along a horizontal axis, where the microtome blade and the tissue chuck are axially displaceable relative to one another along the horizontal axis. The system also includes a control system configured to receive information indicative of a relative axial location of the microtome blade to the tissue chuck along the horizontal axis, and to use a control loop to control the relative axial location of the microtome blade to the tissue chuck such that the one or more tissue sections have a desired thickness.

Abstract: A machine detects a set of first control operations and, in response, causes a display screen to present a graphical interface in which a central window suggests first content by presenting a first preview and a first identifier superimposed on the first preview. The machine then detects a second control operation that indicates dismissal of the first content. In response to the second control operation, the machine causes the display screen to present a transition to an interest-improved version of the graphical interface. The transition includes sliding the first preview, the first identifier, a second preview, and a second identifier together in a shared direction and at a shared speed within the central window. The second preview and the second identifier correspond to second content. In the interest-improved version of the graphical interface, the central window suggests the second content by presenting the second preview and the second identifier.

Abstract: This relates to systems and methods for measuring a concentration and type of substance in a sample at a sampling interface. The systems can include a light source, optics, one or more modulators, a reference, a detector, and a controller.

Furthermore, the systems can be capable of detecting the substance along various locations and depths within the sample by mapping a detector pixel and a microoptics to the location and depth in the sample.

Abstract: Various embodiments are generally directed to techniques for crowdsourcing metadata, such as to create, maintain, utilize, and/or communicate metadata in a datastore. Some embodiments are particularly directed to collecting, managing, and/or distributing metadata via a user interface application (UIA), or an extension thereof. Many embodiments may facilitate collaborative creation of a repository for metadata, such as notes, characteristics, and/or statistics corresponding to data viewed with the user interface application. For example, the comments regarding websites may be collected from a first user via a first instantiation of the web browser extension and distributed to a second user via a second instantiation of the web browser extension. In several embodiments, the metadata may be collected and managed with instantiations of the web browser extension (herein after “WBE instants”) and a data manager may create, maintain, utilize, and/or communicate metadata in a datastore.

Abstract: A vehicle may include a pedal assembly, a motor assembly, and a drive unit that may be used to allow selective usage of one or both of the pedal assembly and the motor assembly to convey power to a driven wheel of the vehicle. The drive unit can include a gearbox that may enclose components which form at least part of a first power path between the pedal assembly and the driven wheel and a second power path between the motor assembly and the driven wheel. The first and second power paths can converge at a component within the gearbox. One-way bearings at points in the first and second power paths prior to the convergence of the power paths can inhibit or prevent the pedal assembly from being affected by operation of the motor assembly, and vice versa.
