Abstract: An outdoor chair has a chair frame, two seat frames, a chair body and two flexible rods. The seat frames are mounted on the chair frame, and each seat frame has a C-shaped upper bent end segment, a C-shaped lower bent end segment and a mounting slot. The chair body is made of fabric, is mounted between the seat frames and has a C-shaped upper edge segment, a C-shaped lower edge and two tubes. The flexible rods are mounted respectively in the tubes of the chair body to tightly mount the chair body between the seat frames. The upper and the lower bent edges of the chair body prevent the chair body from slipping along the seat frames. The upper edge segment of the chair body keeps the upper edge of the chair body from pressing against the neck of a person sitting in the outdoor chair.

Abstract: The invention describes method and apparatus for reducing intermodulation interference caused by reception of undesired signals in wireless receivers. The apparatus comprises an antenna for receiving the desired signal, a low noise amplifier for amplifying this signal, an adjustable attenuator, and a transmitting antenna to transmit the amplified signal to the wireless receiver. By increasing the strength of the desired signal, the present invention eliminates intermodulation distortion caused by the undesirable signals. The invention also describes an apparatus further comprising an adjustable filter for limiting the spectral content of the transmitted amplified signal, and an apparatus for selecting the characteristics of the adjustable filter in accordance with the measured characteristics of the desired and undesired signals.

Abstract: A cellular telephone system is described of the type wherein a plurality of contiguous cells, each having an assigned set of identification codes, are arranged with means for maintaining continuous communication with mobile telephones moving from cell to cell. The system allows multiple access by including means for assigning at least one of the in the assigned set of identification codes to more than one mobile telephone. A unique identification code is assigned to a mobile telephone located in the cell. A signal having a unique identification code is generated for identifying the mobile telephone. The signal is coupled to the zones. A combiner is also provided for combining signals from all of the zones in the cell. A receiver is coupled to the combiner for retrieving the signals having the code.

Abstract: A computer-implemented modeling tool for cellular telephone systems predicts signal strength under real conditions within a building, by considering the effects of inter-building and intra-building structures on transmitted signals. The modeling tool gives more accurate predictions under line of sight conditions, when obstructions occur due to inter-building and intra-building structures.

Abstract: A computer-implemented modeling tool for cellular telephone systems predicts signal strength under real conditions by considering the effects of terrain and man-made structures on transmitted signals. The modeling tool gives more accurate predictions under line of sight conditions, when obstructions occur due to terrain contours, and when mobile or transmitter antennas are blocked by buildings or other structures.

Abstract: A mobile radio telephone communication systems provides for rapid system access and registration of mobile phones when the mobile phone operates in an area outside of its home service area. A preferred mobile phone system for a mobile phone is identified before the mobile phone originates a call by determining a location for the mobile phone and selecting the preferred system from a database stored in the mobile phone using the determined location.

Abstract: An integrated radio frequency communication system, known as a Location-Ruled Radio-Integrated Network (LORRAINE) system, provides integrated voice, data and location services. The radio frequency communications system combines time division multiplexing (TDM) techniques with optional time division duplexing (TDD) or frequency division duplexing (FDD) techniques to provide a plurality of time slot channels for these services. Spread spectrum techniques help reduce noise and interference in the system.
