  • Patent number: 10635190
    Abstract: A three dimensional (3D) cursor maneuvering system for use by a computer or electro-mechanical system requiring 3D control, includes a tinted 2D planar or locally planar reference surface and a color sensitive mobile device that moves along the tinted reference surface and generates high sensitivity and high resolution absolute positional and motional data by accurately determining variations in the tint. Color index data (e.g. CIE 1931 RGB, etc.) on the tinted reference plane varies from place to place and methods are disclosed for imprinting the reference plane with that data in the form of dyes and pigments that may be reflective, refractive or emissive. When the mobile device moves on or over the reference surface, it captures a series of images whose data (e.g. CIE 1931 RGB) varies in correspondence with the movement of the device. The color index data measured by the mobile device can be mathematically converted into 3D positional and motional data.

  • Patent number: 10527417
    Abstract: A high-definition map system receives sensor data from vehicles travelling along routes and combines the data to generate a high definition map for use in driving vehicles, for example, for guiding autonomous vehicles. A pose graph is built from the collected data, each pose representing location and orientation of a vehicle. The pose graph is optimized to minimize constraints between poses. Points associated with surface are assigned a confidence measure determined using a measure of hardness/softness of the surface. A machine-learning-based result filter detects bad alignment results and prevents them from being entered in the subsequent global pose optimization. The alignment framework is parallelizable for execution using a parallel/distributed architecture. Alignment hot spots are detected for further verification and improvement. The system supports incremental updates, thereby allowing refinements of subgraphs for incrementally improving the high-definition map for keeping it up to date.

  • Patent number: 10482859
    Abstract: The inventions relate to the field of electric musical instruments, more particularly, to an optical sensor for a stringed musical instrument with a digital interface and to a stringed musical instrument with a digital interface equipped with said sensor (MIDI—Musical Instrument Digital Interface). Implementation of the disclosed inventions allows to obtain a signal corresponding to vibrations (deflections) of a string in two mutually perpendicular planes, with the influence of the device generating such signals on string vibration parameters being reduced, without signals generated by different strings being mixed and with dimensions of the optical sensor being reduced to allow for its compact placement on a stringed musical instrument.

  • Patent number: 10480964
    Abstract: An optical navigation device has a light-emitting unit, an optical navigation chip and a cover. The light-emitting unit provides a light to a surface of a displacement generating unit. The optical navigation chip has a sensing array, but excludes any optical lens for focusing a reflected light. The sensing array disposed opposite to the surface of the displacement generating unit receives the reflected light which the light provided by the light-emitting unit is reflected from the surface of the displacement generating unit. The cover has a first surface and a second surface, and an angle is formed between the cover and the optical navigation chip, to prevent another reflected light from the surface of the first surface of the cover from entering the sensing array. Particularly, the angle formed between the cover and the optical navigation chip is from 10 degrees to 15 degrees.

  • Patent number: 10481262
    Abstract: An optical sensor measures displacement of a haptic plate that provides haptic sensation to a user. The optical sensor comprises a light source, a plurality of optical detectors, and a controller. The light source is configured to illuminate a surface of the haptic plate in which a haptic wave propagates causing displacement of portions of the haptic plate in one or more directions. The plurality of optical detectors is configured to detect light reflected from the surface of the haptic plate. At least two optical detectors of the plurality of optical detectors are positioned relative to the light source such that an amount of light received at each of the optical detectors is based at least in part on a direction of displacement of the haptic plate. The controller is configured to monitor the haptic wave using the detected light from the plurality of optical detectors.

  • Patent number: 10477355
    Abstract: A surface within a facility, such as a floor, is equipped with electromagnetic sensors that generate data indicative of the presence of objects, such as the feet of users, at or close to the floor. The data may also be indicative of cross-coupling resulting from a transfer of an electromagnetic signal by the object, such as from one foot to another of a user. The data is processed to determine presence of individual object representations, such as representing a foot. Information about object representations such as their movement, cross-coupling, physical distance between, or features of the object representation may be determined. This data may be used to maintain the identity of particular object representations, track object representations over time, determine that particular object representations are associated with a single user and so forth. Adjacent object representations may avoid merging by using a top-down cross sectioning technique.

  • Patent number: 10474111
    Abstract: Apparatus for an alarm clock with one or more alarms that are challenging to deactivate are provided. The alarm clock is fixedly attached to a wall or other surface, and contains a power source such that the alarm cannot be deactivated by unplugging the alarm clock or by easily removing batteries. The alarm(s) may be programmed to activate for a first length of time. To deactivate the alarm, a user must take some action to interact with the alarm clock, for a second length of time, which second length of time is sufficient for the user to become fully awake. Aspects of the alarm clock may be digital or analog, may have manual or electronic or remote controls, may have one or more alarms of different types, and may require different types of user interaction with alarm deactivation components in order to deactivate the one or more alarms.

  • Patent number: 10472873
    Abstract: The present invention provides a door closer control system that includes a door closer having a rack and pinion mechanism connected to a pair of shafts with different length and a pair of springs. The shorter shaft is attached to the pinion of the door closer and will rotate in conjunction with the pinion as the door opens or closes. The shafts have correspondent gears connected to the shafts. The rotation of the first gear will be meshing with the second gear on the second shaft. Electronic sensors are placed on both sides of the door to detect a presence of an object and are activated by the movement of the solenoids. The movement of the solenoids cause a set of springs in the system to engage and disengage from a link to allow free motion of the door.

  • Patent number: 10459113
    Abstract: Apparatus and associated methods relate to activating a blanking programming mode, such as fixed blanking (FB) or floating blanking (FLB), for example, for at least one user-selectable light curtain segment proximally connected to a distal-most segment in a string of cascaded light curtain segments. In an illustrative example, the selective activation may be initiated in response to a request signal from a remote request generator. The remote request generator may, in some examples, communicate the request signal to initiate the programming mode via a wireless communication link. In some embodiments, a request interface module may receive the request signal while releasably plugged into a terminal end of the distal-most segment. In various implementations, the remote selective activation may advantageously empower operators to rapidly configure cascaded light curtain systems that require programming modes for functions such as, for example, FB, FLB, or reduced resolution.
