    摘要: The present invention relates to a novel solar powered patio umbrella device which provides users with an improved patio umbrella capable of automatically expanding and retracting when exposed to sunlight. The device comprises at least one rotating solar panel that powers an automated opening and closing system; and at least one battery that receives power from the at least one rotating solar panel. Thus, the umbrella opens when the battery is at full charge and lowers when the battery is at a lower percentage. In this manner, the device simplifies use of the umbrella and eliminates the need to manually crank the umbrella open to use it.

    摘要: A tubular portion apparatus (10; 100; 300; 400) to be secured and sealed to another tubular (36) is described as is a method of securing and sealing a tubular portion (10; 100; 300; 400) to an existing downhole tubular (36) such as a casing string (36). The tubular portion (10; 100; 300; 400) comprises a central portion (14), an upper (16) and a lower (18) portion adjacent to the central portion (14) along a longitudinal axis of the tubular portion (10; 100; 300; 400). The tubular portion (10; 100; 300; 400) is formed from a main material and an additional material to strengthen the upper (16) and the lower (18) portion of the tubular portion (10; 100; 300; 400).

    摘要: A co-existence method is described. The method comprises setting a priority level of a slot based on the likelihood that the slot will be required by a first radio and signaling the priority level to radio which is co-located with the first radio and which shares a resource with the first radio. The slot may, for example, be a re-transmission slot following a primary transmission slot or may be a sniff anchor point. The likelihood may be determined based on one or more factors, such as historical data or knowledge of the activity of a peer of the first radio.

    摘要: Repeated data packets are generated from a first Bluetooth enabled device to a second Bluetooth enabled device to facilitate radio direction finding of the first device by the second device. A communication connection is established between the first and second devices in accordance with a Bluetooth protocol stack and in response to receiving at the second device a data packet transmitted by the first device the second device transmits an NACK data packet to the first device, whereby the first device is cause to retransmit said data packet, and causing the second device to process at least one of the transmitted data packet and the retransmitted data packet in accordance with a radio direction finding algorithm. The communication connection preferably comprises a remote name request.

    摘要: Sulphided ion exchange resins containing primary or secondary amino groups. They may be obtained by passing a non-aqueous liquid, e.g. a hydrocarbon, feedstock containing elemental sulphur or organic, or inorganic, di-or poly-sulphides through a bed of an ion exchange resin containing primary or secondary amino groups, and so unsulphided ion exchange resins containing primary or secondary amine groups may be used to remove such elemental sulphur or sulphur compounds from liquid, e.g. hydrocarbon, feedstocks. The sulphided ion exchange resins may be used to remove elemental mercury or organic mercury compounds from liquid, e.g. hydrocarbon, streams.

    摘要: A VAR generator is taught in which a thyristor controlled inductive element is used to provide lagging VAR's and a bank of parallel capacitors, each of which may be switched into and out of circuit cooperation independent of the other, is used to provide discrete levels of leading VAR's. The inductive element is utilized in conjunction with the discrete levels of leading VAR's to provide a continuum of VAR generation in the region between the discrete levels by providing continuously variable compensating or cancelling current for interaction with the discrete levels to provide an overall continuous range of VAR generation in the leading VAR region.

    摘要: An inverter circuit using transistors in the switch mode, suitable for induction heating for cooking and sonar applications. Diodes are used in the base circuit of the transistors to postpone conduction and prevent shoot-through, and diodes are used to limit diode recovery time closely to recovery time of transistor base while protecting against base-emitter avalanching.
