Patent number: 8373375Abstract: Embodiments of the invention comprise a multi-input range box driven by multiple electric drives. Range shifting involves momentarily increasing the current through all but a given motor, to a level that will carry the entire load, comprising specified constant power.

Patent number: 8288973Abstract: A telescoping mast with a cabling system configured to cover and store cable within the structure of the mast and able to efficiently extend and retract multiple telescoping sections without jar and minimal energy. The telescoping mast has a hollow mast housing. A telescoping section is nested within the interior of the mast housing. A set of upper pulleys affixed to the upper end of the mast housing, while a set of lower pulleys affixed to the lower end of the telescoping section. A cable is threaded through the first upper pulleys and first lower pulleys such that a first end of the cable is attached to the mast housing and the cable remains taut when the telescoping section is raised or lowered.Type: GrantFiled: January 26, 2010Date of Patent: October 16, 2012Assignee: NS MicrowaveInventor: Thomas Davidson Ford

Patent number: 8288981Abstract: A load control system provides for automatically controlling a position of a motorized window treatment to control the amount of sunlight entering a space of a building through a window located in a façade of the building in order to control a sunlight penetration distance within the space and minimize occupant distractions. The load control system automatically generates a timeclock schedule having a number of timeclock events for controlling the position of the motorized window treatment during the present day. A user is able to select a desired maximum sunlight penetration distance for the space and a minimum time period that may occur between any two consecutive timeclock events. In addition, a maximum number of movements that may occur during the timeclock schedule may also be entered. The load control system uses these inputs to determine event times and corresponding positions of the motorized window treatment for each timeclock event of the timeclock schedule.Type: GrantFiled: September 21, 2009Date of Patent: October 16, 2012Assignee: Lutron Electronics Co., Inc.Inventors: Walter S. Zaharchuk, Brian Michael Courtney, William Bryce Fricke, William H. Howe, Timothy S. Majewski, Joel S. Spira

Patent number: 8278863Abstract: A telescoping mast able to efficiently extend and retract multiple telescoping sections without jar and minimal energy. The telescoping mast has multiple telescoping sections, a position feedback sensor, a motor, a spring motor, and a computation unit. The position feedback sensor is coupled to at least one telescoping section and configured to identify a position of the telescoping sections. The motor is also coupled to the telescoping sections, and raises and lowers the telescoping sections. The computation unit controls the motor based on the position of the telescoping sections.Type: GrantFiled: June 16, 2009Date of Patent: October 2, 2012Assignee: NS MicrowaveInventor: Thomas Davidson Ford

Patent number: 8248005Abstract: A braking circuit is adapted to supply generatively produced energy of the motor as load resistance to a bipolar transistor. The braking circuit has a voltage regulator, which controls a voltage, applied to the base terminal of the bipolar transistor to achieve an associated controlled voltage based on a reference voltage. A first power supply connector of the electrical motor, in the generator mode of operation of the electrical motor, is coupled to a collector terminal of the bipolar transistor and to the voltage input of a voltage regulator. A second power supply connector of the electrical motor is coupled to an emitter terminal of the bipolar transistor and is coupled to a reference input of the voltage regulator via a resistive branch including at least one electrical resistor.Type: GrantFiled: June 23, 2010Date of Patent: August 21, 2012Assignee: Dorma GmbH + Co. KGInventor: Martin Römer
