Title: Non-invasive optical measurement of a blood constituent
Inventor: FINE ILYA
IPC: A61B5/00
Filed: 1999-06-16
Abstract: An over-systolic pressure is applied to a patient's blood perfused fleshy medium. The pressure causes a state of temporary blood flow cessation within a time period insufficient for irreversible changes in the fleshy medium. Release of the over systolic pressure causes a state of transitional blood flow terminating with the normal blood flow. At least two sessions of measurement, separated in time, are executed and at least one of these sessions is selected within the time period including the state of temporary blood flow cessation and the state of transitional blood flow. Optical non-invasive measurement of the concentration of at least one blood constituent are successively performed at these at least two sessions, and respective values of the concentration are obtained.
Patent CA-2333527-A1 (CA)
Inventor: REY CLAUDIO G
IPC: H04L25/02
Filed: 1999-05-25
Abstract: An interpolator (40) having a linear response has a first stage implemented with an IIR filter (42) to achieve the narrow transition bandwidth with relatively few filter coefficients. Zero-stuffing and filtering are used to achieve the interpolation. A forward-backward filtering methodology is then used to achieve a linear phase response for the IIR filter (42). The input sequence to be interpolated is zero stuffed and passed through the IIR filte r (42) a first time. Then the time order of the resulting sequence is reversed  and then passed through the IIR filter (42) a second time. After that, the resulting output sequence is reversed again. Guard blocks are added to both ends of the input sequence and then a block of zeros is appended to the zero - stuffed guarded input sequence. The appended zero block causes the startup a nd ending transient effect of the IIR filter's step response (42) to be equal a t both ends, which tends to improve the accuracy of the interpolation. Subsequent zero-stuffing and filtering by the FIR filter (44) stages are use d to further increase the interpolation. A linear interpolator may also be included after the FIR filter (44) stages.

IPC: H04N5/44
Filed: 1999-05-06
Abstract: An interactive television system configured to display an animated character which has an appearance indicative of a viewer's interaction and time spent watching a particular television program. In one embodiment, the character is a genie which appears more healthy when the viewer's watching/interaction increases and less healthy when it decreases. Various features of the genie, such as hair color, clothing and name, are viewer-selectable. The genie may prompt the viewer for responses, which responses result in the awarding of points to the genie, which in turn make it appear more healthy or give it certain powers or characteristics. The genie is implemented in an interactive application which is transmitted to a set-top box coupled to the viewer's television. Transmission of related data through a return path to the broadcast station which originated the application enables the viewer to participate in lotteries and other special promotions.

Title: Method for forwarding telephone calls and/or addressed files which are sent out electronically via local or global networks
Inventor: WISSING JOHANNES
IPC: H04M3/46
Filed: 2000-02-03
Abstract: The invention relates to a method for routing telephone calls and/or address ed data files which are electronically transmitted via local or global networks . According to the invention the call numbers of several receiving terminals a re memorized under a single identification number and incoming telephone calls and data files whose address contains said identification number as destination number are routed to at least one receiving terminal whose call number is memorized under said identification number. According to the invention each memory location for a call number is permanently assigned to a key of the keyboard of a telephone equipped for digital data transmission or  dual-tone multi-frequency dialing. The sequence in which the keys are actuat ed after activation by means of an input code defines a call routing sequence f or access to the memory locations. The input of the call routing sequence is memorized and terminated by pressing a telephone key which triggers a limiti ng signal. If a telephone call or data file is received under the identificatio n number the memory locations are interrogated in accordance with the defined call routing sequence and said telephone call or data file is routed to the call number memorized in the corresponding memory location.
