Systems, methods and apparatus for wireless charging are disclosed. A charging device has a plurality of charging cells provided on a charging surface, a charging circuit and a controller. The controller may be configured to cause the charging circuit to send pings from a plurality of charging coils using an analog ping process to scan for one or more ping responses from a receiving device in proximity to the charging surface. A subset of charging coils of the plurality of charging coils that received ping responses from the receiving device in response to the sending of pings with the analog process may be determined. Subsequently, the controller then sends pings from the subset of charging coils using a digital ping process. A combination of one or more charging coils of the subset of charging coils may then be selected based on ping responses from the receiving device.

Digital ping selection in a multi-coil wireless charging device

A wireless charging device has a controller and at least one coil that is positioned near the surface of the charging device and configured to transmit an electromagnetic field and a first driver circuit configured to drive the transmitting coil. The controller is configured to cause the driver circuit to provide a charging current to the transmitting coil, decode a request for lower transmission power from a modulation of the charging current, reduce the amplitude of the charging current in accordance with the request for lower transmission power when a temperature measured at a surface of the charging device is less than a threshold temperature, and initiate a cool down sequence when the temperature measured at the surface of the charging device equals or exceeds the threshold temperature. In one example, the request for lower transmission power may be provided in an ASK-modulated signal superimposed on the charging current.

Systems, methods and apparatus for wireless charging are disclosed. A charging device has a plurality of charging cells provided on a charging surface, a charging circuit and a controller. The controller may be configured detect the presence of a foreign object in proximity to at least one charging coil of a plurality of charging coils in the charging device that is selected for supplying charging energy to a receiving device. Additionally, the controller may be configured to determine whether one or more other charging coils is capable of supplying charging energy to the receiving device, and determine, for each of the one or more other charging coils, whether the foreign object is in proximity thereto. Further, the controller may be configured to select at least one of the one or more other charging coils not in proximity to the foreign object for supplying charging energy to the receiving device.

An apparatus and method for providing a water impenetrable barrier between an underground duct and an access opening. The apparatus may cover a secondary opening in a corrugated containment sump of an underground storage tank or the manway of a sanitary sewer, catch basin or other manhole system. The apparatus includes a cover, inflatable seal and a tank of compressed nitrogen to inflate the seal. When sealed to the access opening, the cover restricts the inflow of water or other debris into the interior of the underground duct and nitrogen may be released into the sealed access.

Supplemental lid for corrugated containment sump

An apparatus and method for providing a water impenetrable barrier between an underground duct and an access opening. The apparatus is particularly well suited to cover a secondary opening in a containment sump of an underground storage tank or the manway of a sanitary sewer, catch basin or other manhole system. The apparatus includes a lid, inflatable seal and pressurized tank contained within the lid to inflate the seal. When sealed to the access opening, the lid restricts the inflow of water or other debris into the interior of the underground duct and restricts removal of the lid.

A self-supporting bladder that can be installed into existing storage tanks, particularly into underground storage tanks and a method of forming a double walled tank using the same. This self-supporting bladder serves as the inner wall, utilizing the existing tank as the outer wall of a double wall system, or can provide a double wall system such as through the use of an insert placed in the bladder.

A conduit is connected to the interstice between an outer and inner wall of a storage tank or the liner thereof and may be used to monitor the integrity of the interstice. The conduit comprises a coupling in fluid communication with the interstice, a tube connected at one end to the coupling and having a length sufficient to extend into a riser pipe of the tank. The conduit may also include a bushing holding the tube apart from the tank and providing for the variable positioning of the tube with respect to the tank. A method of monitoring the integrity of the interstice uses monitoring equipment connected to the conduit.

The invention relates to a polyurethane obtainable by reacting a polyisocyanate and a polyol composition comprising a highly branched polysaccharide of randomly bonded glucopyranose units or an alkoxylated derivative of the same. The polysaccharide has an average number of 10&#x2013;100 glucose residues and said polysaccharide and derivative both have an average functionality of 30 or more. The invention also relates to a process for the production of such a polyurethane as well as a mix for the production of a polyurethane comprising a polyol composition, comprising 2&#x2013;100 % of a highly branched polysaccharide, at least one catalyst and at least one surfactant.

A motor vehicle data collection, monitoring and management system is provided for ready connection to the vehicle's onboard data network through the data interface provided by the vehicle manufacturer. The data collected includes data available on the manufacturer's network, such as network data traffic between control modules, as well as data from discrete components located outside of the motor vehicle network. The data collecting and monitoring system exhibits power saving features including automatic shutdown when the motor vehicle is switched off. A methodology for configuring the system is also disclosed.

A fluidized bed combustor or gasifier has a combustion chamber(s) with a non-symmetrical horizontal cross section. The chamber may be trapezoidal, hemispherical, or may have five or more side walls of at least two different lengths. The walls of the combustion chamber may be water tube panels. An external pressure vessel surrounds the combustion chamber(s) and associated particle separator(s), and may be spherical or cylindrical.
