Patent CA-2296824-A1 (CA)
Inventor: BARDSLEY SCOTT
IPC: H04L27/18
Filed: 2000-01-25
Abstract: A DC offset correction arrangement compensates for DC offset introduced into a signal processing path of a device such as a data radio for application to a downstream digital data signal analyzer. During an off-line, calibration cycle, DC offset is measured by a successive approximation DC offset measurement circuit, which stores a multibit output digital code representative of the measured offset. This code is coupled to a DC offset correction circuit, which supplies selected signal processing components, such as a negative feedback low-pass filter coupled and a buffer amplifier, with a correction current that causes the supplied components to inject prescribed portions of a binarily weighted correction voltage that effectively cancels the measured DC offset.

Title: Method and apparatus for automatically controlled gain switching of monitors
Inventor: PRZYDATEK PIOTR B
IPC: G01R21/133
Filed: 2000-02-21
Abstract: A method and apparatus for automatically controlling gain switching of a monitor. To automatically control gain switching, an electronic circuit splits an input channel into a plurality of gain channels. The plurality of gain channels are simultaneously sampled. Thereafter, the processor accesses a present buffer of a first gain channel. The present buffer contains a predetermined amount of samples which represent the input channel. Next, the processor determines whether at least one of the samples contained in the present buffer is saturated. If at least one of the samples is saturated, the processor selects an alternate gain channel. Otherwise, if none of the samples is saturated, the processor determines whether a previous buffer of the first gain channel is saturated. If none of the samples from the previous buffer are saturated, the DSP selects the first gain channel. Otherwise, the DSP selects the alternate gain channel. Thereafter, the samples are processed from more than one of the plurality of gain channels to calculate power parameters.

Patent CA-2304170-A1 (CA)
Title: P53-induced apoptosis
Inventor: KINZLER KENNETH W
IPC: C12Q1/68
Filed: 1998-09-17
Abstract: The most well-documented biochemical property of p53 is its ability to transcriptionally activate genes. Many of the genes which are activated by p53 expression prior to the onset of apoptosis are predicted to encode proteins which could generate or respond to oxidative stress, including one that is implicated in apoptosis within plant meristems. p53 may result in apoptosis through a three-step process: (i) the transcriptional induction of specific redox-related genes; (ii) the formation of reactive oxygen species (ROS); and (iii) the oxidative degradation of mitochondrial components, rapidly leading to cell death. Transcription of other genes is decreased by p53. Examination of the level of transcription of p53-induced or -repressed genes can be used to determine p53 status, to diagnose cancer, and to evaluate cytotoxicity or carcinogenicity of a test agent.

Title: Distributed data storage and delivery in a cellular telephone network
Inventor: JOONG DONALD
IPC: H04M3/533
Filed: 1998-11-24
Abstract: Procedures are disclosed for supporting roaming subscriber mobile station (18) access to stored subscriber data messages. In one aspect, a received subscriber data message is routed for storage and subsequent forwarding/retrieval, not to a "home" message center (20(1)), but instead to a message center (20(2)) either optimally positioned with respect to a current known location of the subscriber mobile station or associated with an initially receiving mobile switching center (30(1)). In another aspect, a mailbox (46) established for a given subscriber mobile station in the home message center is transferred (210), perhaps on a periodic basis, for storage in a local mailbox of a proximate message center within a cellular telephone network (10v) where the subscriber is currently roaming. In either case, the storing message center thereafter performs any requisite operations needed to facilitate message forwarding to or retrieval by the addressee subscriber mobile station.
