  • Patent number: 11821224
    Abstract: A method and apparatus for providing residential care and health is disclosed. The method includes providing a residential unit which is transported to a location proximate a residence of a primary health provider. The residential unit is then positioned on a plurality of height adjustable pads which function to retain the residential unit in place and substantially restrict any horizontal movement of the residential unit relative to the underlying ground. The resident is then introduced into the residential unit. The unit is fitted with telemetric monitoring equipment adapted to monitor and relay information regarding the resident's health, vital signs, movement to a remotely located care provider. Upon the resident obtaining a condition which no longer requires the monitoring of his health and vital signs, the residential unit is transported away from the location.

  • Patent number: 10941824
    Abstract: An extended range, consistent force rail brake comprising an adjustable wedge assembly operatively situated between the main power spring(s) and the brake shoe(s) for selectively taking up the vertical distance that the brake shoe is required to travel between the brake release position and an initial railhead contact position. The adjustable wedge assembly is thus selectively expandable in the vertical orientation, and may comprise: an upper block that is operatively connected, either directly or indirectly, to the power spring; a lower wedge rigidly affixed to a replaceable brake shoe; and an intermediate wedge that is located by suitable bearings and/or linkages for transverse, generally horizontal slidable engagement between the upper block and the lower wedge.

  • Patent number: 10281926
    Abstract: A system for controlling vehicles in a platoon includes a lead vehicle controller on a lead vehicle in the platoon and a following vehicle controller on a following vehicle in the platoon. The lead vehicle controller is adapted to determine a braking distance, based on an initial speed of the lead vehicle and a percent of full service brake application of the lead vehicle, and transmit a braking distance signal indicating the braking distance. The following vehicle controller is adapted to identify the braking distance upon receiving the braking distance signal, determine a percent of full service brake application of the following vehicle based on an initial speed of the following vehicle and the braking distance, and transmit a signal to a following vehicle service brake to apply the following vehicle service brake at the determined percent of full service brake application.

  • Patent number: 8744652
    Abstract: The present invention relates generally to ground transportation systems, and more particularly to a fixed guideway transportation system that achieves a superior cost benefit ratio, is lower in net present cost and thus more easily justified for lower density corridors, and can provide passenger carrying capacities appropriate for higher density corridors serviced by mass rapid transit systems today. According to certain aspects, the present invention provides a braking control system and methodology that enables the implementation of related systems and methods that achieve safe headways at higher speeds than conventionally possible, while maintaining collision avoidance capabilities that support necessary MTBH criteria. In embodiments, a brake assembly for an axle of a vehicle provides redundancy and load-sharing such that failures are guaranteed to not occur above required safety criteria.

  • Patent number: 6907946
    Abstract: A direct braking of a drive shaft for a tracked vehicle that moves on rotating track(s). A disc brake is connected to the same drive shaft that has sprocket(s) for engaging the track(s). Upon activation by a vehicle driver, opposing pistons engage the disc to retard rotation of the drive shaft. This, in turn, causes slower rotation of the tracks and slower movement of the vehicle.

  • Patent number: 6199661
    Abstract: A lubrication system for a railroad locomotive applies a lubricant with great accuracy in computer-controlled, precise quantities behind the last axle of the last locomotive such that the lubricant is consumed by the time the entire train has passed under all track, speed, temperature and train size conditions. Hydraulic pulse-width modulation (PWM or %PWM) controls the quantity of lubricant delivered. Time is divided into a series of windows each consisting of a few seconds. Lubricant delivered from a pressurized tank through long hoses to a solenoid controlled valve is then metered by the duration within this time window for which the computer computes and opens the valve. Compensation is provided for train tonnage and lubricant temperature as well as track curvature and train speed.

  • Patent number: 5992575
    Abstract: The present invention relates to a Personal Rapid Transit system for transporting passengers along a pre-set guideway, and more particularly relates to a future Personal Rapid Transit vehicle braking system. A conventional braking system can not provide the large braking force required for very short headway operation under the effect of weather and environmental conditions due to variations in the available coefficients of friction at the running surfaces. In particular, the Personal Rapid Transit which is a public transportation system can not adopt the conventional braking system since the vehicles are powered by linear motors and are independent of traction. The PRT brake system comprises brake reaction rails (120) mounted on each inside of the guideway and brakes (300) acting on these brake reaction rails (120) as calipers. The brakes are automatically actuated when electric power supply is cut off, and thus can serve as parking brakes and emergency brakes.

  • Patent number: 5065845
    Abstract: A safety apparatus includes a safety device and a centrifugal force speed governor for preventing overspeed conditions of an elevator car in both the downward direction and the upward direction. A bracket attached to the elevator car slidably retains a shaft at right angle to a guide rail attached to an elevator shaft wall. A U-shaped frame is attached to an end of the shaft and rotatably carries a running wheel. A compression spring extends over the shaft between the bracket and the frame to bias the running wheel against the web of the guide rail. On each side of the running wheel, a pair of release levers are rotatably supported to rotate during travel of the car in normal operation. In response to an overspeed condition, the release levers pivot into engagement with a pair of stationary ratchet wheels which are connected with a pair of actuating levers. The ratchet wheels are rotated by the running wheel which movement rotates the actuating levers.
