Patent CA-2310311-A1 (CA)
Title: Phase locked-loop using sub-sampling
Inventor: HAFEZ AMR N
IPC: H03L7/185
Filed: 2000-05-30
Abstract: A PLL-based frequency synthesizer is provided that includes a phase detector, a loop filter, a VCO, a sampler and filter system, and a frequency divider. This architecture reduces the high division ratio (N) necessary in a classical PLL-based frequency synthesizer while maintaining low phase-noise. This is achieved through sub-sampling the VCO output signal in the feedback path. The sampler is placed in the feedback loop following the VCO  and is clocked at a low frequency (sub-sampling). The output of the sampler is the beat frequency between the VCO frequency and the sampling clock (in addition to harmonics that are filtered-out by a low-pass filter (LPF)). The LPF in the feedback loop attenuates any tones resulting from the sampling operation. A frequency divider is then used to bring down the feedback signal to the frequency of the phase detector input. Since the feedback signal has already been reduced in frequency by the sampling operation, the division ratio (N) in this frequency divider is greatly reduced when compared to the classical PLL-based frequency synthesizer. The reduction of the division ratio is beneficial because it reduces the output phase-noise due to the phase detector and the reference signal. Also, if a DDS is used to drive the PLL, the reduced division ratio will also reduce the number of bits needed for the DDS, thus reducing its power consumption.

Title: Automated voice system for improving agent efficiency and improving service to parties on hold
Inventor: SZLAM ALEKSANDER
IPC: H04M3/487
Filed: 1992-05-14
Abstract: A method and an apparatus for improving agent efficiency by reducing non-productive time such as time on hold and time for wrap-up statements. After an agent has been connected to a call the agent may determine that automated handling of the call is appropriate. Depending upon the status of the call the agent may specify that the call has been essentially completed or that the agent is on hold. The agent may speak the name of the connected party and this will be recorded. Then the agent is disconnected from the call and a message playing device, which may also replay the spoken name, is activated. If the response from the connected party indicates that an agent's attention is again needed then the same or a different agent is connected to the call. In addition, a party on hold is provided an estimate of the time before an agent becomes available and/or the number of parties ahead in the holding queue.

Abstract: A method for obtaining an immune response to a non-enteric pathogen antigen (NEPA) such as hepatitis B surface antigen (HBsAg) by feeding the antigen in a plant material to an animal that is immunoreceptive to the NEPA. It has now been discovered that the animal may be made immunoreceptive to the NEPA such as HBsAg by administering the plant material containing the NEPA in conjunction with a suitable adjuvant. The plant material is a substance comprising a physiologically acceptable plant material, especially potatoes, containing the NEPA, e.g.  hepatitis B surface antigen (HBsAg). The NEPA, e.g. HBsAg in the plant results from expression by the plant of the NEPA due to genetic alteration.
