  • Patent number: 7482976
    Abstract: Measurements of frequency and/or phase are taken at the signal ports (S1-S4) of an ISS device (10). These measurements are used to determine phase errors within the ISS device, and phase errors due to the antenna cables (C1-C4). On port, (e.g., S1) is selected as the reference port and then, based on these determined phase errors, offsetting phase errors are determined to correct the phase for the other ports (e.g., S2, S3, S4) with respect to the reference port. The signals at the antenna ports (A1-A4) are then in phase when an omnidirectional antenna pattern is desired from the TCAS antenna array (16). One in embodiment the frequency of the calibration signal is fixed; in another embodiment two different, fixed frequencies are used; and in still another embodiment the frequency is swept to achieve a predetermined measured phase difference.

  • Patent number: 7362823
    Abstract: An arrangement where a transmitter has a plurality of transmitting antennas that concurrently transmit the same symbol, and where the signal delivered to each transmitting antenna is weighted by a factor that is related to the channel transmission coefficients found between the transmitting antenna and receiving antennas. In the case of a plurality of transmit antennas and one receiving antenna, where the channel coefficient between the receive antenna and a transmit antenna [I] i is hi, the weighting factor is hi* divided by a normalizing factor, ?, which is ( ? k = 1 K ? ? ? h k ? 2 ) 1/2 , where K is the number of transmitting antennas. When more than one receiving antenna is employed, the weighting factor is 1 a ? ( gH ) H , where g =[g1. . . gL), H is a matrix of channel coefficients, and ?is a normalizing factor ( ? p = l L ? ? ? q = l L ? ? ? ? k = l K ? ? h p ? ? k ? h qk * ? ) 1/2 .

  • Patent number: 7346360
    Abstract: A system for locating a device in a wireless network that caches a known location and sets an expiration time based on the location. The system correlates the location with known places, such as movie theaters, restaurants, etc. to set the expiration time. For example, if a device was known to be at a movie theater, the expiration time would be set to a longer period of time. However, if the device was determined to be in a moving location, the expiration time would be set to a shorter period of time. The system also includes a mechanism to query the cached location based on a current time of the query and a granularity variable the accounts for a geographic area in which the device is located. The system also accounts for special locations where the mobile device will likely not be moving for long periods of time, or locations where the mobile device may move great distances between determinations of actual location.

  • Patent number: 7328210
    Abstract: An attribute rule enforcer for evaluating the attributes of a call to add, modify, or delete information in a directory, such as a lightweight directory access protocol (LDAP) directory. The attribute rule enforcer determines if the attributes of the call comply with predetermined rules governing the directory's content. The directory attribute rule enforcer may be located at the front end of the directory's access server, and intercepts calls to the directory access server. If the directory attribute rule enforcer determines that the attributes of a call complies with the rules governing the content of the directory, it will forward the call to the directory's access server for action. If, on the other hand, directory attribute rule enforcer determines that the attributes of a call do not comply with the rules governing the content of the directory, the attribute rule enforcer will reject the call. Further, it may forward an appropriate error message to the source of the call.
