  • Publication number: 20110206022
    Abstract: A layer above the MAC and PHY layers of a wireless network employs a forward error correction (FEC) protocol extension with selective acknowledgement to reduce the likelihood of retries to enhance performance in, for example, home entertainment networking applications. In addition, certain system parameters of the wireless network are controlled so as to either i) align required bandwidth with particular sustainable channel parameters of the wireless network, or ii) modify the channel characteristics. One or more of three mitigation techniques might be employed with the FEC protocol extension to enhance maintenance of radio communication in the wireless network: Physical-layer Rate Adaptation, Dynamic Interference Avoidance, and Media-encoding Layer Adaptation.

  • Patent number: 6363146
    Abstract: A reset device is disclosed which may be used in electrical devices such as portable telephones. The reset device includes a source, such as a rechargeable battery, which provides an input voltage and a threshold voltage. The reset device also has a comparator with a first input which receives the input voltage and a second input which receives the threshold voltage. A voltage changing device varies the threshold voltage in response to the output level of the comparator and a rate of increase of the input voltage. The voltage changing device includes a capacitor which delays an increase of the threshold voltage when the input voltage increases. Further, the voltage changing device includes a positive feedback resistor for increasing the threshold voltage when the output level increases. Thus, the positive feedback resistor allows switching the threshold voltage from a first threshold level to a second threshold level when the output level switches from a low level to a high level.

  • Patent number: 6272327
    Abstract: A transceiver is disclosed for use in a wireless handset. The transceiver includes a switch for connecting an antenna, one at a time, to a receiver or to a transmitter. In a reception sub-frame, a limiting circuit switches the switch to an attenuated mode when an output signal of the receiver, such as a logarithmic RSSI signal, exceeds a predetermined value. The limiting circuit includes a comparator for comparing the logarithmic RSSI signal with the predetermined value. In addition, the limiting circuit also includes a transistor which shunts to ground a first control input of the switch when the RSSI signal exceeds the predetermined value. The limiting circuit further includes a shunt circuit to maintain the attenuated mode during a transmission sub-frame to reduce the level of a signal from the transmitter.

  • Patent number: 6111389
    Abstract: In the rapid charging of a Nickel Cadmium (NiCad) battery, the rapid charging is terminated and trickle charging is initiated when any of three conditions is satisfied: a first condition determined by comparing a sensed instantaneous battery voltage with a target voltage; a second condition which is determined by comparing the instantaneous battery temperature with minimum and maximum values; and a third condition determined by comparing an elapsed time of rapid charging with a maximum value. Because battery voltage versus rapid charging time is a function of ambient temperature, the target voltage is determined from an initial measurement of battery temperature, which is assumed to equal the ambient temperature. The target voltage, which is approximately a linearly declining function of ambient temperature, is determined by reading a stored lookup table using the sensed temperature as an index or address.

  • Patent number: 5388149
    Abstract: A public cordless telephone system includes an arrangement for informing a public handset unit when it is within the reception range of a public base unit even though all communication channels are then occupied or all public base units in the reception area are then busy communicating with other handset units. In operation, each public base unit while communicating with any public handset unit inserts in the communication channel it is then occupying spectrum energy such as is provided either by a pilot signal or a frequency shift keying (FSK) signal. By providing this additional spectrum energy along with normal voice signal energy in the communication channel, a public handset unit while searching for an available channel and interrogating this channel will be able to determine, even though the channel is occupied, that there is a public base unit within its reception range.

  • Patent number: 5386457
    Abstract: A cordless telephone public base unit employed in a public telephone system in close proximity with other public base units effectively avoids contention with these other base units for access to a cordless telephone handset unit generating a service request. Contention between the public base unit and the other public base units is resolved by assigning a specific one of a plurality of times during which the base unit may respond to the service request from the handset unit. The time in which the base unit responds to the service request may advantageously be determined by a randomly generated number, the received signal strength of the service request or a combination of these two parameters. Once access to the handset unit is acquired by a base unit and communications between these two units is established on a communications channel, all other handset units and base units are prevented from interfering with the communications between these two units.

  • Patent number: 5371782
    Abstract: In a public cordless telephone system, a cordless telephone handset unit requests and establishes a communications link with a public base unit served by a desired local service provider whenever possible. By generating a service request containing a specific carrier request code, the handset unit selectively identifies an available public base unit served by the desired local service provider and then establishes a communications link with this base unit. In response to receiving the service request from the handset unit, all public base units operated by the chosen service provider respond by providing a first acknowledgment signal. All other public base units respond by providing a second acknowledgment signal. When both such signals are received, the handset unit responds only to the first acknowledgment signal and establishes a communications link with the first base unit providing this signal.
