  • Patent number: 10768615
    Abstract: The present invention is directed toward a system and method for effectively managing, transporting, and taking care of patients in a hospital facility. Primarily this is done through the use of an automated bed with corresponding controls and devices installed within the facility. Precautionary fail safes are implemented such that any medical profession can override the system should an error be detected. Constant monitoring and control of all automated beds may occur from a centralized system. These systems and methods will allow for better allocation of hospital resources, providing much more efficient care to all patients.

  • Patent number: 10760245
    Abstract: An area limit control part as a control section outputs a requested boost pilot pressure for driving a control valve, based upon a pilot pressure in accordance with an operating amount of an operating lever and a posture signal of a posture sensor. A drive permission determination part determines whether or not a drive of a hydraulic actuator is permitted based upon the pilot pressure in accordance with the operating amount of the operating lever. A pilot pressure selecting part selects the requested boost pilot pressure from the area limit control part in such a manner as to drive the control valve with the requested boost pilot pressure to the hydraulic actuator the drive of which is permitted, and not to drive the control valve to the hydraulic actuator the drive of which is not permitted.

  • Patent number: 10755117
    Abstract: A method of determining obstacles determines if a detected object detected outside a subject vehicle is an obstacle for the subject vehicle on the basis of a predetermined determination criterion. In this method, a determination is made whether or not the detected object detected outside the subject vehicle is a driver or passenger of the subject vehicle. When the detected object is not the driver or passenger, a determination is made whether or not the detected object is an obstacle for the subject vehicle on the basis of a first determination criterion. When the detected object is the driver or passenger, a determination is made whether or not the detected object is an obstacle for the subject vehicle on the basis of a second determination criterion with which the detected object is less likely to be determined as an obstacle for the subject vehicle than with the first determination criterion.

  • Patent number: 10754907
    Abstract: A method allowing a user confidentially to query a server including a database. The user builds, from an index of a desired entry, a vector encrypted by a homomorphic probabilistic cryptosystem, and transmits a request having the vector as an argument to the server. The server performs a scalar product between the vector of entries of the database and returns the result to the user. The user decrypts the scalar product to obtain the desired entry. The method can be used for example for querying a location-based service and for navigation by concealed routes.

  • Patent number: 10745014
    Abstract: An inter-vehicle calculation unit calculates a required inter-vehicle distance required between the own vehicle and forward/rear vehicles traveling in the lane to which the own vehicle moves during the lane change. The required inter-vehicle distance includes a first inter-vehicle distance and a second inter-vehicle distance. The first inter-vehicle distance is the distance required to allow the own vehicle or the forward/rear vehicles to adjust their velocity after the own vehicle changes lanes, and the first inter-vehicle distance is calculated by a first calculation unit. The second inter-vehicle distance is the distance required between the own vehicle and the forward/rear vehicles after the own vehicle or the forward/rear vehicles adjust their velocity, and the second inter-vehicle distance is calculated by a second calculation unit. A determination unit determines that the own vehicle can change lanes if the relative distance is equal to or greater than the required inter-vehicle distance.
