Title: Method and installation for transforming a stream of flat articles conveyed in a held manner into an imbricated stream in which the arrangement of the articles is selectable
Inventor: GOSSLINGHOFF REINHARD
IPC: B65H29/04
Filed: 2003-02-25
Abstract: A supply stream (1) of flat articles (8), in particular of printed products, conveyed hanging and held by grippers is transformed into an imbricated stream (2, 3, 4, 5) or into sections of an imbricated stream, in which the articles are arranged in one of two or advantageously four possible ways. For the stream transformation, the articles (8) are selectively deposited on a conveying surface at a first or at a second depositing point (I, II), wherein the articles (8) deposited at the first depositing point (I) or to be deposited at the first depositing point (I) are additionally rotated by 180° (after or before deposition) and wherein the held article edges are, advantageously selectively, leading or trailing on deposition. The selective stream transformation as well as switching from one transformation mode (A, B/B', C  or D/D') to another one are very simple. The stream transformation is suitable in particular for supplying an imbricated stream of printed products selectively to either one of two stacking devices with opposing stacking directions, and for producing e.g. cross stacks (6, 7) in the stacking devices.
Patent CA-2422794-A1 (CA)
Title: Complex valued delta sigma phase locked loop demodulator
Inventor: RILEY TOM
IPC: H03D3/00
Filed: 2001-09-19
Abstract: The demodulator is a multiple stage demodulator. The first stage is a conversion stage which converts an incoming signal into a first complex representation. The second stage is a direct digital synthesizer (DDS)/mixer  which synthesizes a signal to be mixed with the first complex signal and performs the mixing operation to produce a second complex output. This secon d complex signal is controlled by a bitstream fed back from the third stage - a phase quantizer stage. The bitstream represents the quantized phase differen ce between the synthesized signal and the first complex signal. The DDS/mixer stage then measures the synthesized signal for any phase difference from the  incoming signal through the feedback inherent to a PLL, the bitstream thus provides an output that gives the frequency of the desired signal. As a side  benefit, the real component of the second complex signal, provides an amplitude estimate of the desired signal.

Patent CA-2426954-A1 (CA)
Inventor: SULLIVAN MARK C
IPC: G01S19/40
Filed: 2001-10-29
Abstract: A geographic tracking system (10) with minimal power and size required at the mobile terminal (18) collects observation data at the mobile terminal (18), forwards the data to a processor (11), which calculates the position. The mobile terminal (18) needs only to gather a few milliseconds of observation data (from 14-17), and to relay this observation data to the processor (11).  The range from the satellite (13) (or other airborne transponder) to the terminal (18) is determined using the known positions of an interrogating transmitter and a satellite (13), and a known terminal delay between the received signal and the transmission of the return signal, and the round trip time. An arc of locations is determined by computing an intersection of a sphere centered at the satellite (13) having a radius given by the calculated range with a model of the Earth's surface. The candidate points are considered and refined using code phase measurements from a set of GPS satellites (14-17). The candidate point having the lowest residuals or expected to measured code phases is chosen as the location of the mobile terminal (18). The measurements can be refined to account for various sources of error including measurement bias, relative motion and timing errors.
