摘要： An improved proximal cable-less communications system using at least two receivers is described. The system is significantly improved by utilizing an intentional signal path for the local oscillator signal to be radiated while maintaining the architecture of each receiver and the proximal cable-less communications system. The effectiveness of radiation can be increased by extending the length of the electrical interconnect which connects the local oscillator to the mixer. In addition, the effectiveness of radiation is increased by magnetically coupling the electrical interconnect which connects the local oscillator with the mixer with the electrical interconnect which connects the antenna and the mixer. By coupling the two electrical interconnect, the signal output by the local oscillator is induced on the electrical interconnect between the antenna and the mixer. The coupling is set such that the signal induced travels along the electrical interconnect and is radiated out of the antenna.

摘要： An antenna assembly is formed as a thin, unitary element with parallel leads laminated to an insulator. The unitary antenna element includes an integral attachment portion for connection to a printed circuit board. The antenna assembly is usable in electronic devices, such as a cordless telephone radio transceiver. A molded cover, which is directly attached to the electronic device rather than the antenna assembly, is provided to encase and protect the antenna.

摘要： A locator system includes two main components, namely, (1) a beacon tag that is readily attached to a person or article, and (2) a transportable finder or receiver/processor for sensing the relative position of the tag and indicating changes in that relative position to a user. The method for locating a person or article preferably uses an audible feedback signal to the user for informing the user, when moving, whether the relative position of the beacon tag is getting closer to the finder or farther from the finder. The locator system includes at least one beacon tag comprising a transmitter programmed to transmit a unique coded pulse signal. The beacon tag is housed in a lightweight portable envelope or container and includes a battery, an antenna, a large programmed gate array and a frequency reference (e.g., a crystal oscillator).

摘要： An improved proximal cable-less communications system using at least two receivers is described. The system is significantly improved by eliminating the sidetone which can occur in full duplex systems. Components are placed in the receivers, between the mixer components and the components which detect the information encoded in the signal at the intermediate frequency, which function to cancel out the detrimental affect of those signals containing information derived from the modulation of the local oscillator of the receiver device.

摘要： A transmission system or apparatus includes a transmitter or source of transmitted RF or microwave power which is selectively connectable via a transmitter connector to an antenna having an antenna feed via an antenna connector so that a variety of antennas with differing characteristics can be used with a given transmitter. Each antenna preferably has a marker or indicating element incorporated into the antenna feed. The marker or indicating element includes a physically measurable property or parameter corresponding to a physical characteristic of the attached antenna. In the preferred embodiment, the indicating element is a resistance connected in parallel with the antenna feed and having a selected resistance value (e.g., in ohms) which indicates the physical characteristic of gain for antenna. The transmission system also includes an indicating element sensor configured to sense or measure the marker or indicating element and generate a transmitter control signal in response to that measurement. The method for automatically generating the control signal can be implemented in programmable steps as computer software and may include use of a Look Up Table (LUT) having a range of indicator element characteristic values and a range of corresponding transmitter control signal values or, alternatively, can include use of a computation sequence which takes an indicator element characteristic value as an input variable and generates a control signal value in response thereto.

摘要： A video surveillance system includes a video surveillance camera and a frequency hopping spread spectrum (FHSS) transmitter for efficiently and economically transmitting high resolution video signals from the video signal source in the license-free ISM bands (e.g., at 900 MHz, 2.4 GHz, or 5.2 GHz) to a FHSS receiver adapted to receive and demodulate the FHSS signal and generate a complete, intact composite analog video signal directly therefrom. Complete and intact means that all of the composite analog video signal is transmitted and received, including the original line sync and frame sync signals, without requiring any further processing. The FHSS hop duration (or dwell time) and tuning frequency of each frequency hop are selected to permit sensing and modulation of the complete, intact composite analog video signal directly from the analog video signal source, whereupon that complete, intact composite analog video signal is transmitted, hop by hop, to a FHSS receiver, preferably using only the vestigial side band portion of the complete, intact composite analog video signal, to provide a high-resolution, narrow-bandwidth video surveillance system.

摘要： An economical, reliable, robust and easy to use multi-user voice communication system and method suitable for use in rapidly evolving tactical or hazardous situations continuously permits each user to hear every voice communication occurring among the other users, no matter when each user speaks, and no matter how many users try to speak at once. One may characterize this as a wearable party-line radio network, because it works like a wireless party-line telephone service in that all users continuously hear every speaker, even when speaking simultaneously. The system is transportable and operable without requiring any set-up procedure or installation of a central hub or router for controlling a varying number of users when moving. Each user carries a transceiver handset with one transmitter and two or more transceivers tuned to the other transmitters in a group.

摘要： A frequency hopping, spread spectrum transceiver for wireless data telemetry directly modulates data for transmission using minimum shift keying (MSK) modulation; the transceiver includes a transmit Voltage Controlled Oscillator (VCO) to provide an input to a modulator. A programmable attenuator circuit is used between the source of transmit data, the micro processing unit (MPU), and the transmit phase locked loop (PLL) summing junction. The programmable attenuator provides a selectively attenuated data signal that is coupled to the PLL summing junction to generate a modulated data signal for transmission and dynamically adjusts the transmit data stream voltage level as required to achieve a fixed level in frequency deviation based on the present VCO operating frequency. A complete set of VCO characterization measurements is obtained beforehand. The VCO characterization measurements are stored in memory and the MPU controls the attenuation circuit to provide the exact Transmit Data signal level required for optimum modulation depth.

摘要： An economical, compact wireless data telemetry transceiver is adapted to establish and maintain communication links at 2.4 GHZ. The wireless transceiver includes RF and computer control components in a compact package approximately the size of a deck of cards and is adapted to be built into original equipment manufacturer (OEM) products to support a wide range of wireless data telemetry applications. Each transceiver includes a shielded RF board or module with a frequency hopping transmitter and receiver, an antenna, and a digital control board or module. The transceiver functions as a half duplex, bi-directional communication device; transmit and receive functions are time interleaved in a non-overlapping fashion. The RF Board consists of a transmitter, receiver, frequency synthesizer and T/R Switch, each controlled by an external microprocessor to either transmit serial data or receive serial data.
