Patent CA-2313471-A1 (CA)
Title: Programmable linear receiver
Inventor: CICCARELLI STEVEN C
IPC: H04B1/10
Filed: 1998-12-08
Abstract: A programmable linear receiver (1200) which provides the requisite level of system performance at reduced power consumption.  The receiver minimizes power consumption based on measurement of the non-linearity in the ouput signal from the receiver (1200). The amount of non-linearity can be measured by the RSSI slope or energy-per-chip-to-noise-ratio (Ec/Io) measurement. The RSSI slope is the ratio of the change in the output signal plus intermodulation to the change in the input signal. The input signal level is periodically increased by a predetermined level and the output signal from the receiver (1200) is measured. The ouput signal comprises the desired signal and intermodulation products from non-linearity within the receiver (1200). When the receiver (1200) is operating linearly, the output signal level increases dB per dB with the input signal level. However, as the receiver (1200) transitions into non-linear region, intermodulation products due to non-linearity increase faster than the desired signal. By detecting the RSSI slope, the amount of degradation due to non-linearity can be determined. This information is then used to adjust the IIP3 operating point of the amplifiers (1234) and mixer (1230) to provide the requisite level of performance while minimizing power consumption.

Patent CA-2316509-A1 (CA)
Inventor: ZHANG PENG
IPC: H04B3/23
Filed: 2000-08-22
Abstract: An echo canceling system with self deactivation includes an echo canceller based on an adaptive filter, and an echo detector. The adaptive filter determines an estimate of an echo signal present in an untreated signal received from a "near" end of a communications channel. In order to produce an echo-canceled received signal, the echo canceller subtracts the estimated echo from the untreated received signal. The echo detector compares the energy of the untreated received signal and the energy of the echo-canceled received signal. The difference represents the energy in the estimated echo signal generated by the adaptive filter. If this energy is large, significant echo is present. The echo canceller remains activated, and the echo detector selects the echo-canceled received signal for output. If the estimated echo energy is small, little or no cancelable echo is present. The echo canceller is deactivated, and the echo detector selects the untreated received signal for output. Where plural channels of echo cancellation are provided, the deactivated echo canceller may be reallocated to service another communications channel.

Title: Method for replacing a device driver during system operation
Inventor: ASSELIN ALBERT ANDRE
IPC: G06F9/445
Filed: 2001-03-14
Abstract: A method and system for replacing a device driver during system operation provides for hot-swapping device drivers without shutting down a device driver stack.  Particularly useful with file system and file storage devices, the method and system utilize a shell device driver that replaces the physical device driver's entry point interface. The shell device driver has a device driver side interface that calls the physical device driver in response to operating system requests. When an update of the physical device driver is requested, either by an operating system utility or a special upgrade application, the shell device driver receives an update indication.  The shell device driver can then finish required tasks, uncouple and unload the existing physical device driver and couple to the new device driver without disrupting the operating system device interface.

Abstract: A system based on a series of data accumulation hubs, connected together by high speed communication backbone for routing a limited number of data and power cables is suggested. Each hub is connected to arrays of sensor pods which contain the actual sensor elements and minimal, if any, interface electronics. Preferably, as many as 20 sensor pods can be connected to each single hub element wherein a system including five hub elements with 20 sensor pods each would comprise a 100 element array. The data from the individual sensors are accumulated in the hubs, buffered, and conditioned for transmission to the surface data acquisition system through the high speed metal backbone comprising multiple paths of transmission for redundancy in the event of failure. Provisions are made within each of the hubs so that if a hydrostatic leak were to occur, the fault can be isolated and the remainder of the system will function as designed. A power delivery network is also preferably encased within the backbone along with the high speed data link.
