A pool or tank cleaner that is propelled by means of one or more water jets is directed in one or more predetermined systematic scanning patterns of either straight, curvilinear, or combinations of both, by an apparatus and method that controls and varies the directional discharge of one or more water jets that propel the cleaner in its translational movement. The direction of the discharge of the propelling water jet is changed by mechanical sensors, electrical sensors, or by interrupting the water pump. Further variations in the direction of translational movement of the cleaner are effected by activating at least one retractable depending member to periodically contact the pool surface below the moving cleaner, thereby causing the cleaner to pivot or otherwise change direction.

An aircraft conductor sandwich assembly configured to be embedded in a composite aircraft structure. The conductor sandwich assembly comprises a plurality of carbon conductors disposed between two sheets of insulating layers and an adhesive resin bonding the plurality of carbon conductors and the two sheets of insulating layers into a carbon sandwich assembly such that (i) the conductors are electrically isolated and (ii) structural loads can be passed through said conductor sandwich assembly.

A portable communication device including a first wireless transceiver operable under a first communication protocol for transmitting and receiving signals and a second wireless transceiver operable under a second communication protocol for transmitting and receiving signals and a method for controlling transmission of signals from an access point to the first wireless transceiver by limiting transmission of information from the associated access point to the first wireless transceiver to time slots or sub-frames associated with the second wireless transceiver in which the second wireless transceiver does not transmit.

Arrangements (e.g., methods) for manufacturing a display device, including irradiating an amorphous semiconductor film formed on a substrate with an excimer laser beam to convert the amorphous semiconductor film into a polycrystalline semiconductor film; and irradiating predetermined areas of the polycrystalline semiconductor film intermittently with a continuous wave laser beam while a position of the substrate with respect to the continuous wave laser beam is scanned, crystal grains larger than those of the polycrystalline semiconductor film other than the predetermined areas are formed in each of the predetermined areas locally in the polycrystalline semiconductor film, wherein first thin film transistors are formed in the predetermined areas while second thin film transistors are formed in the polycrystalline semiconductor film other than the predetermined areas thereof.
