  • Publication number: 20060010296
    Abstract: Exemplary embodiments of the present invention comprise a method for compressing data for storage in memory. According to one embodiment, the method forms a set of values based on a monotonically ordered series of look-up table values. For one or more paired values in the set, the exemplary method generates a difference of the values in the pair. After replacing one of the values in the pair with a value based on the differences to modify the set, the exemplary method stores final values based on the modified set in memory. The present invention also comprises memory for storing the look-up table values. One exemplary memory comprises a decoder, an encoder, and one or more patterns of crisscrossed interconnect lines that interconnect the encoder with the decoder. The patterns of crisscrossed interconnection lines may be implemented on one or more planar layers of conductor tracks vertically interleaved with isolating material.

  • Publication number: 20050273481
    Abstract: A method and ALU for implementing logarithmic arithmetic in a multi-stage pipeline is described herein. According to one embodiment, a master function is decomposed into two or more sub-functions. Memory associated with the pipeline stores a look-up table for each stage of the pipeline, where each table represents function values generated based on the corresponding sub-function, and where the look-up table associated with one stage differs from the look-up table(s) associated with at least one other stage. Each stage computes a stage output based on the stage input and the corresponding look-up table. By combining the stage outputs, the multi-stage pipeline outputs the logarithmic arithmetic output.

  • Publication number: 20050070320
    Abstract: A communication network supports push-to-talk communications with reduced dispatching delays by eliminating channel grant/request handshaking on the uplink and the downlink. A pool of communication channels can be associated with a group of nets that include one or more mobile terminals. Any terminal can send dispatch traffic immediately on an assigned uplink channel simply by seizing the channel. The network detects such traffic and retransmits it on a downlink channel monitored by the group of nets. Along with the retransmitted traffic, the network sends a net ID and a new downlink channel assignment. Terminals in the targeted net process the retransmitted traffic and non-targeted terminals switch to the new channel. Alternatively, the control channel can be multiplexed to signal traffic channel assignments as needed for all nets, and traffic can be transmitted on the indicated channels for reception by targeted terminals. The reduced delays particularly benefit networks incorporating satellite relays.

  • Publication number: 20050046507
    Abstract: Methods of modulating a radio transmitter. An amplitude modulation signal is generated based on in-phase (I) and quadrature (Q) components of an information signal, and so that it has a reduced predetermined characteristic compared to the magnitude of the I and Q components of the information signal. A complex signal is formed that has substantially the same phase angle variation as the I and Q components of the information signal so that the product of the complex signal and the amplitude modulation signal is substantially equal to the information signal.

  • Publication number: 20040191168
    Abstract: The present invention provides a method for treating cancer by promoting apoptosis and reducing clonogenic survival of cancer cells. The method encompasses co-administering 1) a cell cycle checkpoint abrogation agent (for example, UCN-01 or caffeine) and 2) an inhibitor of a compensatory cytoprotective pathway, such as an agent that inhibits the MEK 1/2 pathway (e.g. PD98059, U0126, or PD184352) or an agent that inhibits the PI 3 pathway (e.g. LIY294002 or wortmanin). In addition, because the co-administration step also radiosensitizes cancer cells, the method additionally encompasses the administration of radiation to further reduce clonogenic survival of cancer cells. The method promotes apoptosis and reduces clonogenic survival in many types of cancer cells, including leukemia cells, prostate cancer cells, breast cancer cells, myeloma cells, and lymphoma cells.

  • Publication number: 20030142234
    Abstract: Television receivers receieve a television signal and downconvert the television signal to generate a complex baseband signal. The complex baseband signal is differeniated and then integrated to reduce a direct current (DC) offset in the complex baseband signal. The television receiever may include a periodic known information field. The known information field is correlated with the integrated signal to determine a residual offset therein that is associated with a constant used in integrating the differentiated complex baseband signal. The residual offset is substracted from this constant when integrating the differeniated complex baseband signal.

  • Patent number: 6532290
    Abstract: In one way to improve the security of bilateral authentication procedures while keeping transmission overhead to a minimum, a first party wishing to initiate communications with a second party generates a random number having a first number of digits. The first party the enciphers the random number using a secret ciphering key to obtain an enciphered version of the random number that has a second number of digits greater or equal to the first number. A third number of selected digits of the enciphered random number are then transmitted to the second party, where the third number is less than the first number. The second party receives the digits transmitted from the first party and expands the third number of digits in a pre-agreed manner to obtain the second number of digits. The second party then deciphers the second number digits using the second party's secret key to obtain the first number of digits, which is not equal to the original random number chosen by the first party.

  • Patent number: 6330292
    Abstract: A matched filter for use in a radio telephone receiver that receives Code Division Multiple Access (CDMA) signals. The matched filter produces precombinations of input values to significantly reduce the number of multiplication and addition operations, compared to conventional matched filters, required to produce a correlation value. This reduced number of required operations, along with a reduced number of delay elements required to despread CDMA signals, significantly reduces the overall power consumption of the matched filter. The use of such a matched filter in a device like a cellular phone, for example, would thus lead to longer battery life.
