摘要:
Chlorofluorocarbon replacement solvents include a main component (first solvent) and a property-modification component (second solvent). The resulting solvent mixtures meet or exceed the solvency, flammability, and compatibility requirements for CFC's while providing similar or improved environmental and toxicological properties. These solvent mixtures can be used in conjunction with refrigeration or heat pumps, electronics, implantable prosthetic devices, oxygen systems, and optical equipment.

There is provided a cellular antenna allowing mechanical azimuth adjustment in combination with adjustment of one or more other antenna attribute such as electrical down tilt, electrical beam width or electrical azimuth adjustment. An integrated control arrangement is provided which can utilise either serial, wireless or RF feed lines to convey communications. A multiband embodiment provides azimuth adjustment for both bands by utilising mechanical and electrical azimuth adjustment. Systems incorporating such antennas and methods of controlling them are also provided.

摘要:
A pouch to be worn by a user for displaying a document. A display window 14 is formed by a pair of flexible panels 16 and 18 joined along or adjacent at least two edges. The display window has an opening for removably displaying a document. Both panels may be transparent, enabling the pouch to be reversible. The panels may be of sufficient flexibility and length to largely circumscribe an extremity of a user; thereby providing for the convenient viewing of a large area of an underlying document. One or more ends 22,26 of the pouch may be tapered to emulate the tapering of the underlying extremity of the user. One or more pairs of complementary attachment elements 40 and 44 are provided for securing the pouch in an observable disposition on the user's body. A foldable attachment flap 128 may be provided to extend the length of the pouch.

A loudspeaker system has of a plurality of relatively small, closely spaced transducer elements, the acoustic outputs of which combine to create a sound field. The transducer elements are individually controlled by a distributed input control circuit, which includes digital signal processing, to synthesize a sound field in front of the transducer elements with a characteristic beam width and direction.

Various apparatus and related methods are disclosed that are capable of detecting surface defects on an optical storage media. One example of an apparatus is configured to direct at least one light signal, which may be from one or more lasers, on an outer surface of an optical storage medium, such as a CD, DVD or the like, which includes encoded data. The light encounters both the optical storage media surface as well as any smudges, scratches, dents, or other defects thereon. Some or all of the light reflected from the defects and the surface are detected by one or more detectors, which may be a photodiode. The detector(s) produce an output signal commensurate with the detected reflected light, which output is processed to determine whether the encoded data may be accurately read from the optical storage media.
摘要:
An electric drive for a vehicle or other machine having a rotatable drive mechanism, in which the torque output of an electric motor is coupled to drive a main generator through a planetary gear set, the electrical output of the main generator is supplied to the motor to drive the motor, and a reaction torque produced in the planetary gear set from the driving of the generator is coupled to drive the vehicle wheels or other motion means. The reaction torque produced in the planetary gear set in response to the generator torque is greater than the electric motor torque input. Start-up and make-up power for the electric motor are provided by an onboard battery recharged by an auxiliary onboard generator, or by the auxiliary onboard generator.

The invention provides a disc inspection and rejuvenation/repair system. The inspection system and rejuvenation/repair system may be provided as separate modules or may be combined in an integrated unit. The integrated unit may be manually operated, or may be an automated system comprising a controller and disk handling system Appertaining methods of operating the system and modules are also provided.

An angled wall cell divider. The invention provides a plurality of planar first walls and a plurality of second walls. The second walls are adapted for interlocking with the first walls such that the first walls are oriented in a spaced apart, parallel relation in a first direction and the second walls are oriented in a spaced apart, parallel relation in a second direction for defining the cells. At least one second wall comprises two acutely angled sides that are otherwise distinct from (a) one another, and (b) the sides of any other one of the second walls, so as to define two respective free edges of the at least one second wall.
摘要:
A bill payment system consistent with the invention comprises a biller generating at least one invoice for at least one customer, the invoice comprising a unique bar code comprising data identifying at least the customer and the biller, and a scanning apparatus configured to scan the bar code and, based on the identifying data of the bar code, to effect payment to the biller in a predetermined amount. In method form, a bill payment method consistent with the invention comprises: generating an invoice for at least one customer, said invoice comprising a unique bar code, said bar code comprising data identifying at least said customer and said biller; and permitting a third party to scan said bar code and, based on the identifying data of said bar code, to effect payment to said biller in a predetermined amount. In another embodiment, a bill payment network consistent with the invention comprises a plurality of billers, each biller generating an invoice for at least one customer, the invoice comprising a unique bar code comprising data identifying at least the customer and the biller, and a plurality of third parties in communication with the billers, each third party capable of scanning the bar code and, based on the identifying data of the bar code, effecting payment to the biller in a predetermined amount.
