Title: Direct digital synthesizer driven pll frequency synthesizer with clean-up pll
Inventor: GILMORE ROBERT P
IPC: H03L7/23
Filed: 1996-03-08
Abstract: A frequency synthesizer (200) which uses a direct digital synthesizer (DDS) (204) to generate a highly accurate periodic signal. The DDS (204) output signal is bandpass filtered utilizing a clean-up phase lock loop (PLL) (214) to produce a spectrally pure reference signal and promote overall fast settling time. A second or primary phase lock loop (220), having a much faster settling time than the first PLL (214), adjusts the frequency of the reference signal generated by the clean-up PLL (214). In one embodiment, the DDS frequency synthesizer (204) has a digital to analog converter (DAC) (206) coupled to the clean-up PLL (214). Another embodiment (300) feeds the most significant bit (MSB) (310) or overflow bit from the DAC accumulator (306) into the "clean-up" PLL (318). Yet another embodiment (400) uses a switching apparatus to bypass the "clean-up" PLL (410) while it is settling on a new frequency.

Patent CA-2217733-A1 (CA)
Inventor: KLAASSEN KLAAS BEREND
IPC: G11B5/60
Filed: 1996-02-09
Abstract: An integrated transducer-electronics interconnection suspension (12) for a disk drive having a high data transfer rate generally above (15) Mbytes/sec between the transducer (9) and the read/write electronics. A suspension (12) supports a slider (10) to which a transducer (9) is mounted and maintains the slider (10) in close proximity to the disk surface. An integrated transducerelectronics interconnection suspension is a laminate structure having electrically conductive traces as part of the structure and connecting the transducer (9) with the read/write electronics. It can support high data transfer rates between the transducer (9) and the read/write electronics by providing means for avoiding sudden changes in the characteristic impedance of the traces to minimize signal reflection on them. The width of the traces are shaped accordingly to prevent abrupt changes in the trace impedance caused by trace bonding areas, apertures and other mechanical obstructions in the suspension. Changes in the traces' direction are gradual to avoid signal reflection. Also, a patterned electrically conductive back plane may be provided in the laminate to better control the trace characteristic impedance. Where a trace crosses above a back plane opening, lateral extensions from the trace's side edges are formed to compensate for the resulting impedance change. In addition, the traces and bonding areas are grouped by signal type, with sufficient spacing between the groups, to minimize cross-coupling of the signals.

Title: System and method for telemarketing through a hypertext network
Inventor: O'NEIL JOSEPH THOMAS
IPC: G06Q30/06
Filed: 1998-03-12
Abstract: A system and method for providing telemarketing services through a hypertext network that interconnects a telemarketing server system with a customer computer and an agent computer.  The telemarketing server accepts a telemarketing request from the customer, and forwards the request to the agent if the agent is available, and to a queue if the agent is not available.  When an agent receives a request, communications are either established between the customer and agent at once, or else scheduled for a later time.  Telemarketing functions are implemented separately from media transport functions through a hypertext network such that the need for geographic centralization of telemarketing agents is eliminated.
