Title: Radar distance measuring device
Inventor: BURGER STEFAN
IPC: H03D9/00
Filed: 1994-09-12
Granted: 1998-09-22
Abstract: A conventional radar module (1) for level measurements is designed for operation within a specific, narrowly restricted frequency range. To enable level measurements to be implemented at a substantially higher frequency without involving any change in the existing radar module (1) whatsoever, a frequency converter circuit (2) is inserted between the duplexer antenna (7) designed for said higher frequency and the antenna port (A) of the radar module (1). This frequency converter circuit (2) which can be realized at small expense converts the lower frequency into the higher frequency in the direction from the radar module (1) to the antenna (7) and the higher frequency into the lower frequency in the opposite direction.

Patent CA-2168204-C (CA)
Title: Improved pop-up towel dispensing system
Inventor: MUCKENFUHS DELMAR RAY
IPC: A47K10/42
Filed: 1994-07-25
Granted: 1999-03-23
Abstract: The present invention pertains to improved pop-up dispensing systems in which edge portions (40, 50) of adjacent towels are non-parallel when the individual towel sheets (10) are interleaved and folded.  This new configuration provides improved pop-up dispensing reliability by providing a predictable, repeatable separation process. The overlapped area (80) formed by the overlapping end edges (40, 50) is tapered such that there is a point across the sheet width with the greatest overlap in the direction of the pulling force and a point across the sheet width with the least overlap in the direction of the pulling force. This configuration allow s the area of maximum overlap to pull the next sheet through the dispensing aperture at the same time that the sheet separation process is starting to take place at the area of least overlap. The separation process begins at the point of least overlap (100) and proceeds across the overlapping area (80) along a "separation front" toward the point of greatest overlap. When the overlapping area (80) is reduced to the extent that there is insufficient overlapping area to sustain the shear forces exerted, complete separation of the two sheets (10) will occur. The area of overlap (80), length of the separation front, and amounts of overlap at the point of greatest overlap can all be tailored to provide desired separation characterized for a particular aperture size, substrate, moistening agent, and moisture loading.

Title: Method and apparatus for controlling bias levels
Inventor: LEWIS DAVID EARL
IPC: G11B11/10
Filed: 1996-02-15
Granted: 2007-04-10
Abstract: An apparatus for controlling the strength of a magnetic field, comprises a first controller (14), a second controller (15), a digital-to-analog converter (16), a current driver (17), and a bias coil (18). The first controller (14) determines the position of the focal point of a lens (29) and passes it to the second controller (15), which provides a digital signal related to the position. The digital-to-analog converter (16) converts the digital signal to a driver voltage and passes the driver voltage to a current driver (17), which provides to the bias coil (18) a bias current related to the driver voltage. The bias coil (18) produces a magnetic field having a strength related to the bias current. The second controller (15) accounts for stray magnetic fields in creating the digital signal. The stray magnetic fields may be constant or may vary in strength based on position of the objective lens (29), circumferential velocity of the storage medium (2, 4), or longitudinal velocity of the storage medium (2, 4). Furthermore, the apparatus may comprise a current sensor (26) for measuring the bias current, and a feedback device for providing to the current driver (17) a feedback voltage related to the bias current.

Title: Ecg filter and slew rate limiter for filtering an ecg signal
Inventor: DEPINTO VICTOR M
IPC: A61B5/308
Filed: 1996-11-26
Granted: 2000-11-14
Abstract: A linear phase high pass filter is disclosed using a slew rate limiter and a linear phase low pass filter in parallel with a delay for removing baseline wander from an ECG signal.  The linear phase low pass filter is preferably a digital Infinite Impulse Response (IIR) filter.  The slew rate  limiter preferably includes a clipper and a unit delay.  An input ECG signal is simultaneously presented to a slew rate limiter and  IIR low pass filter combination and an electronic delay.  Thereafter, the outputs from the slew rate limiter and IIR low pass filter combination and the delay are passed to a summer where the output from the slew rate limiter and the low pass filter is subtracted from the output of the delay to produce the output ECG signal representation.  The combination of the output from the  slew rate  limiter  and  the  low pass  filter being subtracted from a delayed input signal produces a high pass filter.  The resulting high pass filter has a relatively high  -3dB  cutoff  frequency  of  about  .5 Hertz  while providing a virtually constant group delay for the ECG signal passed through the filter.  In this way, distortion of the input ECG signal by the filter is minimized so that the baseline wander portion of the input ECG signals is removed  while  the  part  of  the  input  ECG  signal representative of the heart function is preserved.     The high pass filter is preferably implemented on a microprocessor which may be part of an ECG processing system.  The ECG system may also perform such functions as filtering muscle  artifact  signals  or  supplying  sample points to a video display system, or both.

Abstract: Apparatus and a method for establishing voice band telecommunications connections using a cross connect/switching system (CCSS) for establishing all or part of the connection setments required for individual calls.  The CCSS contains bundles of provisioned paths and also has facilities for establishing individual per call paths which do not use these bundles.  When a call is received, the CCSS switches the call through a combination of provisioned and unprovisioned paths.  In the preferred embodiment, the CCSS is an asynchronous transfer mode (ATM) switch enhanced with converters to communicate with pulse code modulation (PCM) facilities for communicating with other switches and with associated PCM switches. Terminal adapters are provided in either the CCSS or the associated switches or both for processing voice signals to perform functions such as echo cancellation or speech quality enhancement.  Advantageously, such a switch can support a very large node that carries extensive wideband and broadband signal traffic as well as the voice band traffic.
