  • Patent number: 11938326
    Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

  • Patent number: 11167967
    Abstract: A traction control system for a pallet truck includes a traction motor, an operator controlled input device configured to selectively accelerate the pallet truck in both a forward direction of vehicle travel and a reverse direction of vehicle travel, and an operator controlled actuation device configured to place the pallet truck in an auxiliary mode of operation. A vehicle controller may monitor a speed of the pallet truck and, in response to receiving an actuation signal, command the traction motor to maintain the speed of the pallet truck at an intermediate rate of travel without actuation of the operator controlled input device.

  • Patent number: 10233064
    Abstract: A load handling system for a vehicle includes a set of forks that concurrently supports two or more pallets including a first pallet and a second pallet linearly positioned along a length of the forks, and a lifting system to raise and lower the forks. A traction system moves the vehicle in a direction of travel associated with withdrawing the forks from the pallets. Additionally, an actuation device generates an activation signal in response to being actuated by an operator, and a vehicle controller places the vehicle in an automated mode of operation in response to receiving the activation signal. In the automated mode of operation, a front end of the forks moves from the second pallet to the first pallet, and the first pallet is raised while the second pallet remains on a transport surface. The first pallet is then spaced apart from the second pallet by a predetermined distance and then lowered to the transport surface.

  • Patent number: 9981837
    Abstract: In some embodiments, a lift actuator is added to a pallet truck to effect initially lifting a load and a traction command effects fully raising the load while a pallet truck moves. In other embodiments, an electronic controller is programmed to effect initially lifting a load when a lift actuator is engaged and to effect fully lifting the load while a pallet truck moves when a traction actuator is engaged.

  • Patent number: 9205882
    Abstract: In one embodiment, a handle is attached to a vehicle tiller arm. The handle includes a first pair of gripping portions and a second pair of gripping portions. A first throttle actuator is configured and located such that it is operable by either hand of an operator while the operator grasps each of the first pair of gripping portions while the tiller arm is substantially vertical. A second throttle actuator is configured and located such that it is operable by either hand of an operator while the operator grasps each of the second pair of gripping portions and the tiller arm is not substantially vertical.
