Patent CA-2270739-A1 (CA)
Inventor: BRUBECK DAVID W
IPC: H04N7/16
Filed: 1999-04-29
Abstract: A system and method allow for the periodic re-configuring of broadcast receivers to control their storage of responses to interactive applications during a polling period. A broadcast server maintains a database of interactive applications each preferably associated with a program that will be broadcast. When the program is broadcast, an interactive application is inserted into the broadcast feed and delivered to a broadcast receiver such as a television set-top box. The broadcast receiver includes a processor, memory, and other hardware necessary to execute the interactive application. When executed, the interactive application generates a response which is transmitted to a local data center at, for example, the cable head-end. Generated responses have specific types. To manage the number and capacity of the system to receive responses, priority values are assigned to responses of different types. The priority values are based on the value of the responses to the provider of the interactive application, and established with respect to total response capacity, and an estimated response volume during a palling period. These priority values are assigned or updated preferably once each polling period, and transmitted to and stored in the broadcast receivers. teach broadcast receiver uses the priority value assignments to determine if it will execute and store responses for a currently received interactive application, or reserve memory capacity for higher priority responses.

Title: Radio environment analysis apparatus
Inventor: KUWAHARA YOSHIHIKO
IPC: H04W24/08
Filed: 1999-06-01
Abstract: A radio environment analysis apparatus includes a receiver and signal processor. The receiver receives a signal modulated by phase shift keying (PSK) using a pseudo noise (PN) code sequence by an array antenna at a plurality of fixed points on the plane, converts the received signals into intermediate frequencies or demodulated signals, and outputs them.      The signal processor processes a signal output from the receiver to analyze the arrival angle, delay time, and relative power of the signal incoming to the receiver.      The signal processor has a plurality of normalization units, first estimation unit, arithmetic unit, and second estimation unit. The normalization units individually normalize signals from the receiver and output them as a normalized signal group. The first estimation unit calculates a covariance matrix, and estimates the arrival angle of each incoming signal.      The arithmetic unit calculates a weight of the array antenna for suppressing incoming signals except for an incoming signal having the estimated arrival angle, and calculates the product of the weight of the array antenna and the normalized signal group. The second estimation unit calculates a covariance matrix and estimates the delay time and relative power.
Patent CA-2273999-A1 (CA)
Inventor: GEDCKE DALE A
IPC: H03M1/06
Filed: 1998-09-25
Abstract: A method for improving the speed of convergence to sub-least-significant-bit accuracy and precision in a digital signal averager when the measurements are averaged over many samples where the noise inherent in the signal is not large compared to 1 LSB. A slider offset circuit (10) implements the method which adds offsets to an analog input signal acquired from an analog sensor (20). The slider offset circuit (10) compensates for limitations in the resolution of an analog-to-digital converter (28) by adding a sub-least-significant-bit offset to the input signal. Similarly, the slider offset circuit (10) compensates for the differential non-linearity using a Gatti offset which are whole number multiples of the average voltage bin width. Speed of convergence to sub-LSB accuracy is further improved by employing non-consecutive increments in the two sliders (22, 24).
