Patent number: 11917493Abstract: UE location determined by collecting and preprocessing signal data at a detector and sending extracted data to a remote locate server. The detector buffers samples from signals provided by receive channels, detects known reference signals from receive channels based on reference signal parameters, isolates symbols carrying the reference signal from frames, extracts data from symbols, and sends extracted data to locate server. The locate server receives the extracted data, estimates locate observables based on the extracted data and calculates the UE location based on the estimated locate observables, the reference signal parameters and the extracted data. The detector and/or the server may also generate correlation coefficients between reference signals carrying spectrum received from a serving cell and utilize the correlation coefficients to cancel a serving cell signal in symbols that include known in advance reference signals from the serving cell and one or more neighboring cells of the wireless system.Type: GrantFiled: June 10, 2022Date of Patent: February 27, 2024Assignee: QUALCOMM Technologies, Inc.Inventors: Felix Markhovsky, Truman Prevatt, Russ Markhovsky, David Goodwin Shaw, Tyler Matthew Smith

Patent number: 6628780Abstract: A network-based CODEC (coder-decoder) includes an echo canceler. This CODEC recognizes the presence of a data call by detecting predefined signaling portions of a modem handshaking process. For each detected data call, the CODEC uses a stored channel model for performing echo cancellation during the data call. The CODEC trains off-line during selected segments of the modem call and then stores the new channel model for use in a future data call.Type: GrantFiled: October 31, 1997Date of Patent: September 30, 2003Assignee: Lucent Technologies Inc.Inventors: Donald Lars Duttweiler, David Goodwin Shaw

Patent number: 5982950Abstract: A method and system for acquiring an optical target affixed to a surface of a package with an optical scanning device. Height information associated with the height of the surface of the package is sensed and a height signal representative of a scanning distance between the optical target and the optical scanning device is generated. The package surface is scanned with the optical scanning device to generate an optical target input signal. The optical target input signal is converted in accordance with a first sampling frequency to provide a converted input signal, and a second resampling frequency is adjusted in accordance with the height signal. The converted input signal is reconverted in accordance with the second resampling frequency to generate a frequency shifted optical target signal, and the optical target on the surface of the package is acquired in accordance with the frequency shifted optical target signal.Type: GrantFiled: October 28, 1994Date of Patent: November 9, 1999Assignee: United Parcel Services of America, Inc.Inventors: Govind Shah, David Goodwin Shaw, Donald Gordon Chandler
