20110031040 | STATIC PRESSURE ANTI-STOW LOGIC FOR PLATFORM WHEELCHAIR LIFTS - A method for detecting weight on a platform lift having a platform, a hydraulic cylinder, and a hydraulic circuit including the steps of measuring a static pressure of the hydraulic circuit, and comparing the measured static pressure to a baseline pressure of the hydraulic circuit. The baseline pressure is a static pressure of the hydraulic circuit without external weight positioned on the platform. | 02-10-2011 |
20130327032 | Hydraulic System and Arrangement for an Access Arrangement - A hydraulic system for an access arrangement having a platform configured for movement between a deployed position and a stowed position, the hydraulic system including: at least one hydraulic power unit configured to urge hydraulic fluid through a hydraulic circuit; at least one hydraulic cylinder directly or indirectly connected to a portion of the platform and configured to urge the platform towards at least one of the stowed position and the deployed position, wherein the at least one hydraulic cylinder is in fluid communication with the hydraulic power unit; and a pressure regulating valve in a path between the at least one hydraulic power unit and the at least one hydraulic cylinder, wherein the pressure regulating valve is operable to prevent the at least one hydraulic cylinder from urging the platform to the stowed position if a load on the platform exceeds a specified threshold. | 12-12-2013 |
20150044006 | INSTALLATION METHOD AND ARRANGEMENT FOR A WHEELCHAIR LIFT ARRANGMENT - A wheelchair lift arrangement configured to be installed in a preexisting structure includes a lift base assembly including a lift base plate and two supports attached to the lift base plate; and at least one installation bracket connected to each of the supports, respectively. Each installation bracket includes a horizontal portion and a vertical portion. The horizontal portion and the vertical portion of each installation bracket are each configured to connect the respective installation bracket and the lift base assembly to the preexisting structure at a separate location. | 02-12-2015 |
20150107911 | LOAD SENSING SYSTEM FOR WHEELCHAIR LIFT ARRANGEMENT - A load sensing system for a wheelchair lift arrangement includes an elongated member that is rotatable about a longitudinal axis between an unloaded position and a loaded position; a biasing member that biases the elongated member toward the unloaded position; at least one contact member connected to the elongated member and configured to contact a bridge plate; and a switch assembly operatively connected to the elongated member, the switch assembly being configured to be activated to prevent operation of the wheelchair lift arrangement when the elongated member is in the loaded position. A method of regulating movement of a lift platform of a wheelchair lift arrangement is also provided. | 04-23-2015 |

20100219807 | METHODS AND SYSTEMS FOR TRANSMITTING AND RECEIVING DATA FROM POINTS ALONG VOLTAGE TRANSMISSION LINES - A method of receiving signals transmitted through a voltage carrying power line using an antenna module including the steps of: positioning a housing of the antenna module proximate to the voltage carrying power line such that an antenna being supported in the housing is oriented at an angle with respect to the voltage carrying power line, and receiving a signal via the antenna from the voltage carrying power line. | 09-02-2010 |
20100223018 | SYSTEMS FOR MONITORING DATA FROM POINTS ALONG VOLTAGE TRANSMISSION LINES - A transceiver module for monitoring a voltage distribution network that includes a voltage carrying power line and a transmitter along the voltage carrying power line for transmitting a first monitoring signal that includes information related to the condition of the voltage distribution network. The transceiver module comprises a receiver located along the voltage carrying power line at a distance from the transmitter, the receiver configured to receive the first monitoring signal; a sensor that monitors a condition of the voltage distribution network and produces a sensor signal that contains information related to the condition being monitored; and a monitor in communication with the receiver and the sensor thereby receiving the first monitoring signal and the sensor signal, the monitor configured to provide a second monitoring signal that includes the information contained in the first monitoring signal and the sensor signal. | 09-02-2010 |
20100294037 | GAUGE ASSEMBLY AND METHODS OF USING SAME - A gauge assembly measuring an amount of a liquid, for use with a float arm assembly including a float arm pivoting in response to a change in the level of liquid, and a flange housing a first magnet and coupled to the float arm where the movement of the float arm causes a displacement of the first magnet. The gauge assembly includes a support adapted to be attached to the flange, which includes a second magnet, spaced in relationship to the first magnet and having a different strength than the first magnet, and an electronic circuit positioned proximate to the first and second magnets to provide a signal representative of the position of the second magnet wherein the second magnet is displaced by the first magnet in response to the level of liquid. The gauge assembly includes a display associated with the second magnet for showing the level of liquid. | 11-25-2010 |
