US Classification:

455424000, 455423000

Abstract:

There is provided a wireless network detector that easily and conveniently enables a user to scan and find access points for one or more wireless network present in a scanned location. The detector can provide visual and audio feedback about the detected wireless networks. The wireless network detector can provide information to a user, including, the strength of a signal, network identifying information such as network SSID, whether encryption is enabled, etc. The wireless network detector can translate technical network SSIDs or labels into descriptive and understandable text, symbols or names that can be displayed to the user. In one aspect, the wireless network detector scans for transmissions of IEEE 802.11 wireless access points to obtain configuration characteristics relating to a detected wireless fidelity network. The wireless network detector can be configured to detect selected wireless networks and to display detection results only for selected or related wireless networks.

Appl. No.:

8/846751

Inventors:

Mark A. Birchler - Roselle IL
Debra A. Jones - Schaumburg IL
Nicholas C. Oros - Schaumburg IL

Assignee:

Motorola, Inc. - Schaumburg IL

International Classification:

G01S 502
H04B 7185

US Classification:

342357

Abstract:

Signals comprising time of transmission indications relative to a common time base (302) are transmitted by at least two fixed transceivers (110-116). When the signals are received by a mobile unit (160), a time of reception indication relative to the common time base is calculated for each signal. Pseudo-ranges are calculated based on the time of transmission and time of reception indications, and a WLS solution location estimate is calculated based on the pseudo-ranges. Essentially the same procedure may be performed on signals transmitted by the mobile unit. Given the common time base between the fixed transceivers and the mobile unit, only two or more signals are required to determine the location estimate. Where GPS receivers are used to supply the common time base, location determinations can still be made when a GPS solution is unavailable.

International Classification:

G06G 778
G01S 302

US Classification:

701207

Abstract:

Signals exchanged between a fixed infrastructure (110-116) and a mobile unit (160) give rise to M channel quality metrics. The channel quality metrics are mapped, via predetermined relationships (501-503), in to M corresponding time of arrival variances, which in turn are used to derive M-1 time of arrival differential variances. A time of arrival differential weighting matrix including, in part, the time of arrival differential variances, is used to calculate a WLS solution, which solution is an estimate of a location of the mobile unit. This procedure may be implemented using an infrastructure-based location processor (130) operating in conjunction with the mobile unit, or may be performed by either the location processor or mobile unit alone.

International Classification:

G01S 7/35
G01S 7/40

Abstract:

A radar apparatus measures at least one characteristic of at least one object. A sweep generator generates a sweep signal to modulate an oscillator to generate a varying frequency signal. A transmitter transmits the varying frequency signal as a radar signal. A receiver receives a reflected radar signal to produce a received signal using the varying frequency signal. A compensation signal memory holds a previously stored compensation signal. A compensation circuit compensates the received signal based on the previously stored compensation signal to produce a compensated received signal. A quiet switch quiets the reflected radar signal and determines the previously stored compensation signal, during calibration of the radar apparatus, and the received signal is written into the compensation signal memory. Switched loads can be used to quiet the reflected radar signal. For field calibration, the compensated signal can be adjusted but not necessarily written back into the compensation signal memory.

Abstract:

A radar apparatus measures at least one characteristic of at least one object even in a near field. A sweep generator generates a sweep signal to modulate an oscillator to generate a varying frequency signal. A transmitter transmits the varying frequency signal as a radar signal. A receiver receives a reflected radar signal to produce a received signal using the varying frequency signal. A compensation signal memory holds a previously stored compensation signal. A compensation circuit compensates the received signal based on the previously stored compensation signal to produce a compensated received signal. A frequency transformation circuit transforms the compensated received signal to produce a frequency spectrum signal. A peak detector measures the characteristic of the object based on a peak of the frequency spectrum signal. When operating in a calibration mode and the reflected radar signal is quieted, the received signal is written into the compensation signal memory.
