  • Patent number: 7869801
    Abstract: An embodiment is a method for configuring a terminal (e.g., a radio) over a radio control channel. Instead of requiring on-site technicians to physically connect to the radios or error-prone and time consuming data calls to individual radios, an embodiment broadcasts software and configuration data as part of one or more radio control channel messages. As the radio control message or multiple messages are broadcast, any radio listening to the radio control message(s) may be configured. Additionally, radios of a particular type will be configured to use the same version of software and configuration data.

  • Patent number: 7831217
    Abstract: An external speaker/microphone apparatus for a radio transceiver includes a speaker, a microphone, a push-to-talk switch, and an emergency switch. The apparatus further includes an encoder module operatively coupled to the push-to-talk switch and the emergency switch and configured to generate a digital identification each time the push-to-talk switch is pressed, and a digital emergency signal and digital identification when the emergency switch is pressed. The apparatus also includes a connector configured to operatively couple audio to the speaker from the transceiver, a combination audio signal from the microphone and the encoder module to the transceiver. The connector is further configured to operatively couple the push-to-talk switch and the emergency switch to the transceiver so that the transceiver is switched to a transmit mode when either the push-to-talk switch or the emergency switch is pressed.

  • Patent number: 7830832
    Abstract: A distributed Internet Protocol (IP) voting system and method for use in Land Mobile Radio (LMR) Systems having a central send-and-receive site and one or more receive-only sites. In the distributed voting system, receive-only sites are directly linked to the control point using a network and associated packet transmission protocol. This may be a high-speed asynchronous data link such as a standard IP network link. Each remote site receiving digital data, calculates a bit error for that data. This error calculation is incorporated into the data header information. The data header information and data are placed in an IP packet and transmitted as a User Data Protocol (UDP) message to the control point. The control point selects the lowest bit rate data message, or the first control message, and retransmits it using a standard radio air interface protocol, such as the APCO Project 25 air interface protocol.

  • Patent number: 7801559
    Abstract: A method for transmitting and receiving digitally modulated wireless signals using an analog FM transceiver is provided. The analog FM transceiver has a transmit speech audio frequency band, a receive speech audio frequency band substantially equal to the transmit speech audio frequency band, a subaudible frequency band, a direct microphone audio input, and a direct speaker audio output. The method includes generating, in a baseband digital spectrum translator external to the analog FM transceiver, a baseband transmit signal occupying frequencies substantially within the transmit speech audio frequency band of the analog FM transceiver. The method also includes applying the generated baseband transmit signal to the direct microphone audio input to thereby transmit a digitally encoded RF TX signal having a constant envelope and using the analog FM transceiver to receive a digitally encoded RF RX signal with a constant envelope and to generate a baseband receive signal using the digitally encoded RF RX signal.

  • Patent number: 7791316
    Abstract: A system of optimally recharging a battery cell while powering a device connected to the battery pack, in which an electronic switch connects a battery pack power-output either to the battery cells or to a second power-input contact. When not recharging, the battery-pack power-output contact is connected to the battery cells, thereby powering the device from the cells. When recharging via a charging unit, the battery pack's power-output terminal is uncoupled from the cells and coupled to a power source of the charging unit, thereby powering the device from the charging unit. At the same time, a voltage is supplied to the battery cells, thereby recharging them. The switching may be activated by a voltage supplied by the charging unit to a temperature monitoring thermistor in the battery pack. In this way, the battery pack's power output may be automatically switched whenever it is placed in the charging unit.

  • Patent number: 7773710
    Abstract: A method and system is provided for improving bit error rate (BER) performance in delay spread fading conditions, such as the fading associated with simulcast systems. BER is improved through novel symbol synchronization that comprises oversampling an input signal and filtering the samples to determine a composite symbol sample point that converges toward the center of the signal's effective eye pattern. The composite symbol sample point may be an average of previous composite symbol sample points and an instantaneous sample point determined based on samples from a synchronization field of the signal. The updated composite symbol sample point may be utilized for future sampling of the incoming signal.

  • Patent number: 7711342
    Abstract: An apparatus includes a filter module, an amplification module, and an adjustment signal source. The filter module generates a filtered signal based on a received signal. This filtered signal has a level shift corresponding to a difference between a direct current (DC) level of the filtered signal and a DC level of the received signal. From the filtered signal and an adjustment signal, the amplification module generates an amplified signal. The adjustment signal, which is provided by the adjustment signal source, may control (e.g., diminish) an effect of the level shift on a DC level of the amplified signal.
