摘要： A cordless telephone system is arranged for extending the operating range of a cordless telephone portable unit within such system. The cordless telephone system comprises a plurality of cordless telephone stations that plug into any available wall telephone jack and may share the intrapremises telephone wire-pair with one or more existing corded telephone stations without interference. Each cordless telephone station consists of a cordless telephone base unit and its associated cordless telephone portable unit. Although each of the portable units is associated with a particular base unit, all of the portable units are able to operate with any of the base units in the system. As a user of a portable unit with a call in progress roams about a premises, all base units monitor the quality of the radio frequency signal received from the portable unit. If the signal quality of a base unit actively communicating with the portable unit deteriorates to below an acceptable level, control apparatus in the system identifies another base unit and executes a hand-off of the communication link with the portable unit to this base unit that is then receiving the signal from the handset unit with an acceptable signal quality. Operational control for the base units is provided through a time division multiple access arrangement wherein a communications channel is imposed on the existing premises telephone wire-pair above the audio frequency band used for standard telephone service.

摘要： An extended operating range is provided for a portable or handset unit operating within a cordless telephone system. The system employs multiple base units and multiple handset units, with only one of the multiple base units being activated at a time for communicating with a given handset unit. Each of the multiple handset units has an assigned or dedicated base unit with which only it may communicate. Other shared base units with which all the multiple handset units may communicate are also located in the system which supports multiple simultaneous users. An associated radio link control unit controls the activation and deactivation of the base units which are dispersed through a premises. This control unit also controls the connection of a voice path to the base unit actively communicating with a handset unit. As a user of a handset unit with a call in progress roams around the premises, this base unit monitors the quality of the signal received from the handset unit. If this signal quality deteriorates to below an acceptable level, the base unit notifies the radio link control unit which, in turn, initiates a polling procedure to identify and hand-off the communications to another base unit that is then receiving the signal from the handset unit with an acceptable signal quality. With no calls in progress, both base unit and handset unit transmitters are off thereby avoiding interference to other nearby cordless telephones. All receivers are active, however, in order to respond to incoming calls and service requests. Channel cycling and base unit polling procedures are advantageously employed to insure that incoming or outgoing calls are completed quickly, even though the location of a roaming handset unit may be unknown.

摘要： In a resonator in which a ground plane and a patch sandwich a dielectric, a slot in the patch concentrates emanation of radiation from the slot. Shorting conductors form the ends of the resonator. A dielectric cover over the slot matches the dielectric constant of the substrate to that of free space. Quarter-wave chokes at the ends of the resonator suppress currents in the ground plane.

摘要： A telescoping antenna structure suitable for use in a portable transceiver for increasing the level of radiated or received r-f energy while in a collapsed position and also obtaining the maximum permitted level of radiated r-f energy while in an extended position. The increase in r-f energy in the antenna while in the collapsed position is obtained through use of a projectable sliding member affixed to the antenna which comes in contact with and makes electrical changes to antenna tuning circuitry when the antenna is adjusted from the extended position to the collapsed position.

摘要： The invention is a processor based analysis system with appropriate interface that includes multiple fish surrogates that each have a plurality of piezoelectric and triaxial accelerometer sensors for emulating sensory organs of a particular fish. The multiple fish surrogate array is immersed in flowing water intakes of a hydraulic structures such as intakes, intake bypasses, and diversion structures, and natural geological formation such as riffles, shoal areas, and pools. The invention is an interface system for data acquisition analysis and perspective display of acoustic and fluid dynamic data in or near these hydraulic structures and/or natural formations. To accomplish this, multiple sensors in each of the fish-shaped surrogate physical enclosures that form the array are deployed at the same time to describe a fish's aquatic environment at the hydraulic structure location. The gathered data can then be correlated with fish behavior for the purpose of developing methods of diverting fish from such areas of danger of a water intake or to attract them to a water bypass entrance system.

摘要： The effectiveness of a microstrip conductor antenna, such as a patch antenna, is improved at any particular frequency by making the thickness of the conductor sufficiently small to reduce shielding and losses caused by the skin effect and make currents at the upper and lower surfaces couple with each other and make the conductor partially transparent to radiation. In one embodiment the thickness is between 0.5.delta. and 4.delta.. Preferably the thickness is between 1.delta. and 2.delta. where .delta. is equal to the distance at which current is reduced by 1/e., for example 1.5 to 3 micrometers at 2.5 gigahertz in copper. According to an embodiment, alternate layers of dielectrics and radiation transparent patches on a substrate enhance antenna operation.

摘要： Dielectric components extend between top and bottom surfaces of a ground plane in a resonant microstrip patch antenna over a distance of one-quarter-wavelength of a resonant frequency of the antenna. The components form quarter-wave chokes within which waves cancel with reflected waves and reduce currents in the bottom surfaces of the ground plane. This reduces back lobe responses.
