  • Patent number: 10131371
    Abstract: A cart is disclosed which is capable of being wheeled to a vehicle and mounted thereon through a mount secure coupling attached to the cart and a secure receiver attached to the vehicle. Upon secure attachment to the vehicle, the carts undercarriage assembly including wheels are capable of being retracted into the top deck assembly of the cart. Therefore, the vehicle maintains clearance from the road even after the cart is attached. Upon reaching a destination, the undercarriage of the cart is lowered and the cart is detached from the vehicle. The cart is then able to be wheeled away. The cart allows for transportation of loads without the need for the operator to actually carry either the load or the cart at any stage from start to finish or perform any additional steps to safe and securely attach the cart to the vehicle.

  • Publication number: 20180304035
    Abstract: A respiratory mask includes a mask frame and a soft mask pad. The mask frame includes a ring-shaped base which is disposed at the front end of the mask pad, and a pair of wing portions which are connected to two opposite sides of the ring-shaped base and each of which is formed with a free end face. The mask pad includes an abutting portion, and is transformable between a non-sealing state, where the abutting portion is separated from the free end faces, and a sealing state, where the abutting portion abuts against the free end faces.

  • Publication number: 20170299424
    Abstract: A computer system measures noise in an urban environment using data records providing a location of a noise, a time stamp associated with the noise, and a noise category. Such data records are sparse with respect to both locations and time. The computer system also accesses other information that defines correlations of among different locations and among different time slots. Such correlation data can include geographic information and historical sample data. By applying this correlated information to the sparse data records about noise, the computer system can derive noise level and noise category information over a larger geographical area. Such information can be provided continually based on received data records about noise, typically in a matter of minutes after receiving the noise data for any given time slot.

  • Publication number: 20170285181
    Abstract: A computer system measures traffic speed on a road network. Sensors provide location data, over time, for a sampling of vehicles on the road network, such as a fleet of vehicles. This location data from a sampling of vehicles is sparse with respect to both road segments in the road network and time. From the location data, the computer system generates sample data associating speed of sampled vehicles on the road segments to points of time in a plurality of time slots. The computer system accesses other information that defines correlations among different road segments and among different time slots. The computer system derives at least an average vehicle speed for each road segment in the road network for at least the current time slot using the correlation data and the sparse sample data. The computer system can infer traffic volume from average vehicle speeds, and then compute environmental data.

  • Patent number: 9622781
    Abstract: Described herein are external fixation systems for correcting bone deformities in adjacent bones or fragments thereof. The systems herein include first and second elongate rods that translate with respect to one another via rotation of an actuation member at an end of one of the rods. At least one housing is coupled along a length of one of the rods. The at least one housing includes at least one pin clamping member for clamping an end of a fixation pin therein. When the at least one pin clamping member is in an unlocked state, the fixation pin can rotate in polyaxial directions. When in a locked state, the angle of fixation wire with respect to the rods is set. The locked and unlocked state of the at least one pin clamping member is determined by the positing of a fixation member with respect to the housing it is coupled to.

  • Patent number: 9186180
    Abstract: Disclosed herein are external fixation devices including at least an elongate rod, a housing and an actuation member. The housing is coupled to the elongate rod and the actuation member is rotatably coupled to the housing such that a central longitudinal axis of the actuation member is angled and offset with respect to a central longitudinal axis of the elongate rod. Rotation of an actuation portion of the actuation member about the central longitudinal axis thereof in a first radial direction causes the housing to translate along the central longitudinal axis of the elongate rod in a first direction.

  • Patent number: 9071486
    Abstract: The disclosed embodiments provide a system that tracks and compensates for input signal noise at a receiver of a data communication channel. In particular embodiments, the receiver of the data communication link receives an input signal which comprises two signal levels. Next, for each of the two signal levels, the system generates an error signal by comparing the input signal value of the signal level with an expected signal value for the signal level. The system then updates a threshold signal value based on at least one of the two error signals associated with the two signal levels. Finally, the system compensates for input signal noise in the received input signal using the updated threshold signal value.
