    摘要: An array antenna includes a dielectric substrate layer having opposing sides. A ground plane conductor is positioned on one side of the dielectric substrate layer. A plurality of antenna elements, such as slots, are formed within the ground plane conductor. The antenna elements are arranged to form an array. A plurality of signal tracks, such as striplines, extend along the side of the dielectric substrate layer opposing the ground plane conductor. The respective striplines extend under each antenna element. A plug-in card slot is operatively connected to the plurality of striplines and adapted for receiving a plug-in card and connecting to a plurality of striplines within the plug-in card to have a desired phase shift to scan the beam to a desired location.

    摘要: A system and method of remotely recording a telephone message at a selected recording device connected to a telephone receiver by an RF link may include a base station having an RF transmitter connected to a telephone receiver, and plural paging/recording devices, each with an RF receiver and a message recorder. The paging/recording devices may be contained within suitable children's toys, or within pager-like packages. A caller calls the telephone receiver and when the telephone connection has been made provides a first code signal to the telephone receiver to gain access to the RF transmitter, and then provides a second code signal to identify a particular paging/recording device that is to receive and record the message.

    摘要: In an oil well instrumentation system, the downhole sensor system is controlled by a computer which is powered-on only during sampling movement. An independent circuit, continuously powered, detects significant sensor rate-of-change values whereby the computer-sampling equipment is powered-on. A self-contained memory gauge includes either semiconductor or magnetic core memory for retaining downhole information related to sampled parameters, such as borehole temperature and pressure. A microprocessor-based computer manages the power utilization by independently and selectably energizing and deenergizing different sections of the gauge. The magnetic core memory is tested for operability, and the addressing of the magnetic core memory is adjusted in accordance with any inoperable memory locations. Samples of the monitored environmental conditions can be taken at variable rates dependent upon software monitoring of the condition, the remaining battery life and the remaining memory capacity and in response to hardware monitored pressure changes. Each sample can be taken to a selectable resolution. A watchdog circuit monitors the microprocessor to insure that it is operating within a preselected time limit.

    摘要: The power-conversing apparatus includes a plurality of independently energizable electrical circuits used in receiving electrical signals from a transducer which senses an environmental condition, in processing the electrical signals, and in storing information related to the detected environmental condition. The apparatus further includes a power control circuit for continuously providing electrical power to at least one of the electrical circuits and for independently switchably providing electrical power to selectable ones of at least two others of the separately energizable circuits.
